Terms of service

Version 2.0 · Published 27 October 2026. For new customers these Terms apply from that date. For customers who signed up earlier, they apply 30 days after we emailed them this version. Earlier versions are available on request.

Who we are. SirenDM, a software business in the Czech Republic. Email: support@sirendm.app. In these Terms, "SirenDM", "we" and "us" mean SirenDM.

These Terms are for businesses that use SirenDM CRM: agencies, creators, partners and their team members. They do not apply to fans.

Key terms

These are the terms that put the most risk on you. The full text is in the sections named.

  1. You disclose AI. We provide the AI and the tools; you decide how your agents reply. We strongly urge you to say that AI is used in your bio and first message, and you must tell the truth when a fan asks. We cannot check or guarantee what you do. (Section 6)
  2. Platforms can ban you. Automating a Telegram user account, or connecting 4Based or f2f.com through your own login session, may break those platforms' rules. They can limit or ban your accounts, freeze balances or change their systems at any time. Unless we caused it, that is not a fault in our service and we are not liable for it. (Section 10)
  3. AI makes mistakes. You set the persona, prices and rules and you supervise your agents. We do not check each AI message before it is sent. (Section 11)
  4. We are not liable for lost profit or sales, Platform bans, the content of AI messages, or fines for your own breach. Any other liability is capped at the fees you paid us in the 12 months before the claim. The only exception is where the law does not allow liability to be limited. (Section 19)
  5. Your use of the Service is your responsibility. Your accounts, content, chats, prices, fans and team, and following the law and Platform rules, are on you. If something goes wrong because of how you use the Service, you carry it, including any claim or cost it causes us. (Sections 4.2 and 18)
  6. Claims against us must be brought within one year. (Section 19.6)

1. The contract

1.1 These Terms are a contract between us and the business that opens the SirenDM account ("you"). It is made when you accept these Terms at signup and we open your account.

1.2 The contract is made of:

Our Privacy Policy explains how we handle your own personal data. It is information, not contract terms. If these Terms and the DPA conflict on personal data, the DPA wins. A written agreement signed by both of us (for example a partner agreement) wins over these Terms on the points it covers.

1.3 These Terms are in English. Translations are for convenience only. The English text prevails.

2. Words we use

3. What the Service does

3.1 The Service lets you run AI agents that chat with your fans, send free teasers and offer locked photos and videos at prices you set. It connects to:

3.2 You choose how each chat runs: Full AI (the AI replies on its own), AI Assist (a person reads and sends AI drafts), manual, or paused.

3.3 Other features include media vaults, follow-ups, mass messages, AI voice notes, fan analytics, payments in chat and an API for partners. AI voice notes run on a Fish Audio or ElevenLabs account that you connect with your own key. Your contract with that provider governs it, and you must hold the voice owner's written consent (section 7.1(b)).

3.4 To run the Service we connect to your accounts from our servers, through proxy providers we choose, and we send fan messages and context to AI model providers. Our providers are listed in the DPA.

3.5 Changes. We may add, change or remove features at any time.

3.6 Beta features. Features marked "beta", "preview" or "coming soon" are provided as they are. They may change or stop at any time and are excluded from any commitment in these Terms.

3.7 No uptime promise. We work to keep the Service running, but we do not promise any level of availability. The Service depends on Platforms and providers we do not control.

4. Who does what

SirenDMYou
EU AI ActProvider of the AI agent system. We design it, write its core instructions and choose the AI models behind it.Deployer of your agents. You decide to use them, on which accounts, with which persona, content, prices and mode.
GDPR, fan dataProcessor, acting on your instructions under the DPA.Controller of your fans' personal data.
GDPR, your account dataController (see the Privacy Policy).—
Selling to fansNot the seller.The seller. Your fans buy from you.

4.1 We write the system's default instructions, safety rules and default replies. You choose and change the persona, scripts, example replies, media, prices, follow-ups, languages and mode. You are responsible for what you choose.

4.2 You are solely responsible for how you use the Service: your accounts, Your Content, your agents' settings, your chats and sales, your fans, your team and your API users, and for following every law and Platform rule that applies to you. The Service is a tool. What you do with it, you do at your own risk. Everything sent from your accounts is yours, whether you, your team or the AI wrote it.

5. Who may use the Service

5.1 You may use the Service only:

5.2 By signing up and by using the Service you confirm that the above is true and that you have authority to bind your business.

5.3 Give us true and current details about who you are. We may ask for proof of identity or of your business, and our payment partners may run their own checks. We may refuse or close an account where we cannot verify you.

5.4 You are solely responsible for all activity under your account, and for securing and backing up Your Content. This includes everything done by your team members and with your API keys and connected Platform sessions. Keep logins and keys secret. Tell us at once at support@sirendm.app if you think someone has misused them.

5.5 Team members must be 18 or older and must follow these Terms. You are responsible for them as for yourself.

6. Telling fans about AI

6.1 Our part. We are a technology provider. We provide the AI and the tools to run it; you decide whether to use AI, on which accounts and chats, and how your agents reply. We built tools so you can tell fans about AI: you set the reply your agents send when a fan asks whether they are talking to AI, or have such chats handed to a person, and you can review, pause or switch off AI on each account and chat. We strongly urge you to disclose AI in your bio and in your first message to each fan. We do not control how you set up or use these tools and cannot guarantee that you or your agents disclose AI.

6.2 Your part. You run your accounts and decide how AI is used on them. On every account where AI writes or helps write messages, you must:

  1. say clearly in the bio or profile that AI is used to write messages;
  2. tell the truth when a fan asks whether they are talking to AI, a bot or a real person, through the Service's AI reply or by answering yourself;
  3. never set up your agents, personas or team to make fans believe AI is a real person;
  4. label AI-made images, video and audio as AI-generated;
  5. add any other notice the law or a Platform requires where your fans are.

6.3 AI Assist. If a person on your team reads and sends every message, those messages are your team's messages. Approving drafts without reading them does not count.

6.4 If you do not do what 6.2 asks, that is your breach, and we may suspend the agent or your account.

7. Your content and the people in it

7.1 You promise that, for all Your Content:

  1. everyone shown is 18 or older and was 18 or older when it was made;
  2. you hold written consent from every person shown to be filmed or photographed, to have the content sold and sent to fans, and, for voice models, to have their voice used;
  3. you keep age and identity records for every person shown (for US-facing content, records that meet 18 U.S.C. § 2257 where it applies), and you name a custodian of those records;
  4. you own the content or have a licence to use it as you do through the Service;
  5. it is lawful where you are and where your fans are.

7.2 You must give us copies of the records in 7.1 within 2 business days of our request. We may ask whenever a Platform, a card scheme, an authority or a complaint requires it, or when we have doubts.

7.3 You must not upload or send:

7.4 Other people in your content. If anyone other than you appears in Your Content, or contributed to it, you must first get their fully informed written consent, signed and dated, and keep a copy of their government-issued ID and that consent on file. We may ask for these records for anyone in your content at any time. You alone are responsible for rights, permissions, joint authorship and any revenue split with them, and any claim about such content must be brought against you or the person featured, not us.

7.5 If you break this section, we may remove the content, restrict what you can upload or sell, suspend or end your account, bar you from opening new accounts, and refer serious cases to the authorities.

7.6 Records law. We are not a "producer" of Your Content under 18 U.S.C. § 2257 or similar laws. You are, and you keep the required records and name their custodian.

7.7 We do not check all content and we are not obliged to. We may review any content at any time, ask for the records in 7.1, refuse to make content available for sale, and remove it.

8. Fans' age and safety

8.1 You must not knowingly let your agents chat with, flirt with, or sell to anyone under 18. Where the law in your fans' countries requires age verification before sexual content is shown (for example the UK Online Safety Act, US state age-verification laws or Australian codes), you must meet that duty on the channels you run.

8.2 Checking fans' age is your responsibility. Fanvue, 4Based and f2f.com run their own checks on their users. On Telegram and web chat, any age check the law requires is yours to run.

8.3 Under 18. When a fan says or strongly signals that they are under 18, you must at once stop all sexual content and all sales in that chat and block the fan. The Service may stop the agent and hand such chats to a person.

8.4 Web chat. Our web chat does not check age. You must not use it to send sexual photos or video to people in the UK, Australia, or US states whose laws require an age check before such content is shown.

9. Personal data and messages to fans

9.1 You are the controller of your fans' personal data. You must:

  1. give your fans a privacy notice that covers the Service, including AI processing and the AI providers listed in the DPA;
  2. have a lawful basis for all processing. Sexual chat reveals data about a person's sex life, which the GDPR treats as special-category data. In practice the lawful basis is the fan's explicit consent, and you are responsible for getting it;
  3. handle your fans' requests (access, deletion and so on). We help as the DPA says.

9.2 Marketing messages. You must not use the Service (mass messages, cold DMs, outreach, follow-ups to people who never wrote to you) to send marketing messages to people who have not agreed to receive them, where the law requires consent. In the EU and the UK it almost always does, for individuals and businesses alike (ePrivacy Directive Art. 13; Czech Act 480/2004 Sb. § 7; UK PECR reg. 22). Telegram's anti-spam rules also apply.

9.3 Do not use the Service to collect fans' data for any purpose other than chatting with and selling to those fans, and do not export it in breach of the law or of a Platform's rules.

9.4 Your terms with fans. Your sales to fans are between you and your fans. You are responsible for your own terms with them, including, where the law allows, getting the fan's consent to immediate supply of digital content and their acknowledgment that this ends any right to cancel, and for refunds you owe them.

9.5 The DPA sets out how we process fan data for you, including security, providers, international transfers, breach notices, audits and deletion.

10. Platforms

10.1 Platforms are independent of us. Each can at any time limit, suspend or ban your accounts, delete chats, freeze or revoke balances (including Telegram Stars and Fanvue creator balances), change or close its API, or block our connectors.

10.2 You connect your accounts knowing that:

  1. running a Telegram user account through automation, and sending messages in bulk, may break Telegram's Terms of Service, API Terms and anti-spam rules;
  2. the 4Based and f2f.com connectors use your own login session. Those platforms have not given us a published API, and may treat automated access as a breach of their rules;
  3. Fanvue's rules require AI-generated media to be clearly labelled and ban falsely depicting live interactions.

10.3 You are responsible for following each Platform's rules on your accounts, including rules on AI disclosure, adult content, payments and advertising. We do not promise that any Platform or ad network allows your use.

10.4 A ban, limit, lost account, lost balance, withheld payout, API change or outage caused by a Platform is not a defect in the Service, does not entitle you to a refund, and we are not liable for it. This does not apply to the extent the loss was caused by our own breach of these Terms.

10.5 Telegram Stars and Platform payouts go to your own Platform accounts. We do not hold them.

11. AI output

11.1 AI replies are generated automatically. They can be wrong, off-tone, repetitive, out of character, or not what you would say. They can make claims about the persona that are not true.

11.2 We do not review any message before it is sent. You choose the mode, persona and rules and you must supervise your agents and chats. Use AI Assist wherever you want a person to check each message.

11.3 We are not liable for the content of AI messages, or for sales won or lost because of them.

11.4 We do not promise any level of sales, revenue or results.

11.5 The Service is provided as it is and as available. We do not promise that it will suit your needs or be secure, error-free or always available.

12. Acceptable use

12.1 You and your team members must not use the Service to:

  1. chat with, sell to, or target minors;
  2. send or store anything listed in section 7.3;
  3. pretend to be a specific real person who is not you, unless you have that person's written permission;
  4. deny being AI, or work around section 6;
  5. offer or suggest in-person meetings, escort services or other sexual services;
  6. use false hardship, fake deadlines or emotional pressure to get fans to pay, or target fans who appear vulnerable, distressed or dependent;
  7. send marketing messages without a lawful basis (section 9.2);
  8. defraud fans, launder money, evade sanctions, or break any law;
  9. break into, overload, reverse-engineer or resell the Service, or share accounts or API keys outside your business;
  10. evade a Platform's ban or limit by using the Service;
  11. promote your accounts in a misleading way, impersonate SirenDM, or suggest that we endorse you.

12.2 Under the DPA, you instruct us to access your account, agents, media and chats where needed to give support, fix problems, keep the Service secure, and check content for legality and compliance with these Terms.

13. Fees, credits and payment

13.1 Prices. The prices and fees on our Pricing page when you buy apply. They are made of a monthly subscription per connected account, credits for AI usage, and a fee on your fans' purchases. The fee is worked out on the price the fan pays, at the rate shown on the Pricing page when the sale is made. Free or bonus credits have no cash value. We may offer, change or withdraw signup credits, discounts and other promotions at any time.

13.2 How you pay. Subscriptions and credit packs are charged to your card through Stripe. Crypto top-ups go through CoinGate. The subscription renews every month until you cancel it.

13.3 Credits.

  1. Credits are a revocable, non-transferable licence to use the Service. They have no cash or stored value, are not money, and cannot be exchanged for cash, sold, given away or moved to another account.
  2. We may change the price of credits, the packs on offer and how many credits each feature or fee uses.
  3. Free, signup and bonus credits are given at our discretion. We may reduce or cancel them at any time, and they expire 90 days after they are given unless we say otherwise.
  4. Bought credits expire after 24 months in which no credits were added or used on your account. Expired credits are not refunded and we do not have to remind you before they expire.
  5. We may suspend, cancel or remove credits for a breach, suspected fraud, chargebacks or where the law requires it, without giving reasons unless the law requires them.

13.4 Auto top-up. If you switch on auto top-up, we charge your saved card for the pack you chose when your credit balance runs low. You can switch it off at any time in the dashboard.

13.5 How we collect the sales fee. We deduct credits equal to the fee from your credit balance. Your credit balance can go below zero.

13.6 Card sales.

  1. We do not process your fans' card payments or hold money from your sales. Card payments for your content are processed by our payment partner Lustify under its own terms. Your fans buy your content from you. You must follow Lustify's terms and pass any check it requires.
  2. Refunds, chargebacks, chargeback fees and fines that the card schemes or Lustify charge because of your sales are yours.
  3. We may stop card sales for an agent or for you at once if Lustify, a card scheme or an acquirer asks us to, or if continuing would put our relationship with Lustify at risk.

13.7 Negative balance. A negative credit balance is an amount you owe us. We may charge it to your saved card or deduct it from credits you buy later.

13.8 Late payment. If a payment fails or your balance is negative, we may pause your agents at once until it is paid.

13.9 Refunds. Fees and credits are not refundable, including when credits expire, when your account is suspended or closed, or when we discontinue the Service or a feature, except:

  1. when you end the contract because of a change to these Terms (section 21);
  2. when we end the contract without your fault: we refund prepaid subscription fees for the unused period;
  3. where the law requires it.

13.10 Taxes. Prices include or exclude VAT as the Pricing page says. Where the reverse-charge rule applies, you account for the VAT. You pay any taxes on your own sales to fans. We are not responsible for your taxes and do not give tax advice.

13.11 Price changes. We may change prices with at least 14 days' notice by email. The change applies from your next billing period after the notice ends. If you do not accept it, cancel before then.

14. Suspension

14.1 We may suspend or restrict all or part of the Service for you (for example one agent, card sales or outreach), with or without notice, where we reasonably believe that:

  1. you or your team broke section 6, 7, 8, 9.2 or 12;
  2. continuing would break the law, a court or authority order, or a Platform's or card scheme's rules, or put fans, minors, other customers or us at risk;
  3. a Platform, Lustify, a card scheme or an authority asks us to;
  4. there is a security threat to your account or the Service; or
  5. you have not paid (section 13.8).

14.2 A suspension can last as long as we need to review the facts.

14.3 We usually tell you why, but we may withhold reasons, for example to protect an investigation, unless the law requires them. Lifting a suspension is at our sole discretion.

14.4 Fees keep running during a suspension caused by you. We are not liable for loss caused by a suspension made in good faith under this section.

15. Ending the contract

15.1 You may cancel your subscription at any time in the dashboard. It ends at the end of the paid month.

15.2 We may end the contract:

  1. with 7 days' notice, for any reason, with a refund under section 13.9(b);
  2. at once, by notice, if you breach section 6, 7, 8, 9 or 12, keep breaching these Terms after a warning, do not give records under section 7.2 on time, or do not pay within 30 days of our notice, or if a Platform, Lustify or an authority makes it unlawful or impossible for us to serve you.

15.3 After the contract ends:

  1. agents stop and access ends;
  2. you can ask for an export of your data under section 16 within 30 days;
  3. we delete fan data and Your Content as the DPA says, except what the law requires or allows us to keep;
  4. sections that by their nature should survive do so, in particular sections 13 (amounts owed, chargebacks), 16, 17, 18, 19, 20 and 23.

15.4 After a breach. If we suspend you or end the contract because of your breach, unused credits are forfeited unless the law requires a refund, and you must not open a new account or use someone else's to get around it.

15.5 Deleting your account. Deleting your account is permanent. Cancel your subscription and export what you need first. We may keep billing records, the record that you accepted these Terms, and data needed to establish or defend a legal claim, for as long as the law allows.

16. Leaving and taking your data with you

16.1 You may switch to another provider at any time. Tell us at support@sirendm.app. The notice period is at most 2 months, and you can choose a shorter one.

16.2 Within 30 days of your request we give you an export of your exportable data that we still hold (agents and their settings, scripts and texts, fan lists, conversation history, sales records and your media) in a common machine-readable format.

16.3 This section follows the EU Data Act (Regulation (EU) 2023/2854, Arts. 23–31).

17. Intellectual property

17.1 Your Content stays yours. You give us a non-exclusive, worldwide, royalty-free licence to host, copy, transform (for example thumbnails, transcriptions and AI descriptions), send to AI providers, and send to your fans Your Content, only to provide the Service to you, keep it secure and comply with the law. The licence ends when Your Content is deleted, except for copies we must keep by law or that sit in backups until they expire.

17.2 The Service is ours. The software, prompts, models, defaults and documentation belong to us or our licensors. You get a non-exclusive, non-transferable right to use the Service during the contract, for your business.

17.3 AI output. As between you and us, you may use the messages your agents produce. We do not promise that AI output is original, protected by copyright, or free of third-party rights.

17.4 Feedback. If you send us ideas, we may use them freely.

18. Claims caused by you

18.1 You defend, indemnify and hold harmless us and our owners, staff and contractors against any claim, loss, fine, damages, settlement and cost (including reasonable legal costs) arising from:

  1. Your Content, and the chats and sales on your accounts;
  2. a breach of these Terms, the DPA, a Platform's rules or the law by you, your team members or your API users;
  3. your processing of personal data, including your fans'; or
  4. instructions you gave us.

18.2 This applies whoever brings the claim, for example a fan, a rights-holder, a Platform, a payment partner or an authority.

18.3 If someone makes a claim against us that falls under this section, we tell you promptly, and you cooperate with us. We decide how to handle and settle the claim.

19. Our liability

19.1 Cap. Our total liability to you under or in connection with these Terms and the DPA is limited to the fees you paid us in the 12 months before the event that caused the claim.

19.2 Exclusions. We are not liable for:

  1. lost profit, lost revenue, lost sales or lost business opportunity;
  2. indirect or consequential loss;
  3. loss caused by a Platform (section 10.4);
  4. the content of individual AI messages (section 11.3);
  5. loss to the extent it results from your failure to meet your own duties under sections 6 to 9 or the law, including fines imposed on you for your own breach;
  6. loss of data you could have exported or backed up;
  7. loss caused by other users, fans or third parties;
  8. loss caused by inaccurate account details or poor security of your logins, keys or devices;
  9. unauthorised access to, or deletion of, data caused by you or by systems outside our control;
  10. loss that was not a foreseeable result of our breach when the contract was made.

19.3 What the cap and exclusions do not cover. Sections 19.1 and 19.2 do not apply to harm we cause intentionally or by gross negligence, to harm to a person's natural rights (such as life, health, privacy or dignity), or anywhere else the law does not allow liability to be limited.

19.4 Force majeure. We are not liable for failure caused by events outside our reasonable control that we could not have foreseen or overcome. Platform actions are covered by section 10, not by this section.

19.5 The Service is provided for business use. Apart from what these Terms say, we give no other promises about it, to the extent the law allows.

19.6 Time limit. Claims against us must be brought within one year from the day they could first be raised. This does not apply to claims for harm to life, health or freedom, or from intentional breach.

20. Confidentiality

20.1 You keep our non-public information (including our prompts, scripts, defaults, prices and how the Service works) confidential and use it only to use the Service. This does not cover information that is public or that must be disclosed by law.

20.2 Personal data is covered by the DPA, not by this section.

21. Changes to these Terms

21.1 We may change these Terms at any time, for example because of a change in the law, a Platform's rules, our features or our providers.

21.2 We post the new version here with its date and email you about important changes. A change takes effect 14 days after we email you, or at once if the law or a Platform requires it or if it is only in your favour.

21.3 If you do not agree, you may end the contract before the change takes effect, and we refund prepaid subscription fees for the unused period. If you keep using the Service after that, you accept the changed Terms.

22. Reports, takedowns, complaints and appeals

22.1 Reports. Anyone can report content on the Service they believe is illegal or breaks these Terms at support@sirendm.app. Include your contact details, where the content is, what is wrong, and any evidence. We assess each report and may ask the reporter or you for more information.

22.2 Intimate images shared without consent. The person shown, or someone authorised to act for them, can ask us to remove intimate images, including AI-made "digital forgeries", by sending: their signature (typed is fine), where the content is, a short statement that it was published without consent, and their name and email (or the representative's name, email and relationship). We act as soon as reasonably practicable and in any event within 48 hours of a valid request, take reasonable steps to remove copies, and may remove content before we finish reviewing it. We tell the uploader without revealing who asked.

22.3 Copyright. A rights-holder can send a copyright notice (in English) with: a signature, the work concerned, where the infringing material is, their address, phone and email, a statement of good-faith belief that the use is not authorised, and a statement that the notice is accurate and they are authorised to act. We may remove or disable the material without notice and without liability to you, and tell you. If you think it was a mistake, you can send a counter-notice with the same details and your consent to the jurisdiction of the courts; we pass it on and may restore the material if the rights-holder does not start legal action within 10 to 14 business days. We may end the accounts of repeat infringers.

22.4 What we may do. We may warn you, remove or disable content, restrict features, stop card sales, or suspend or end your account, as we consider appropriate (sections 7, 14 and 15). We may keep content and records as evidence and refer matters to the competent authorities without telling you first. Where the law requires us to report, we do. We are not obliged to share detailed findings with anyone unless the law requires it.

22.5 Appeals. If we act against your content or account, you can appeal by email within 14 days of our notice. Say which decision you challenge, why it is wrong, and add any new evidence. We decide within a reasonable time. We may look at late appeals but do not have to. Our decision on an appeal is final, without affecting any right the law gives you.

22.6 Misuse. Knowingly false, abusive or bad-faith reports, takedown requests, copyright notices, counter-notices or appeals break these Terms.

22.7 Points of contact (EU Digital Services Act, Arts. 11 and 12), for authorities and for users: support@sirendm.app. Languages: English and Czech.

23. Governing law and courts

23.1 Czech law governs these Terms and the contract, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.

23.2 The Czech courts with jurisdiction for Prague decide disputes. We may also bring a claim in the courts where you are established.

24. Other terms

24.1 Notices. We send notices to your account email, and they count as received the next business day. You send notices to support@sirendm.app.

24.2 Transfer. You may not transfer the contract without our written consent. You agree in advance that we may transfer the contract to a company we control or that takes over the SirenDM business. The transfer takes effect when we notify you.

24.3 Partners and the API. If you use our API, these Terms apply to that use too, together with any API documentation and rate limits we publish. A signed partner agreement takes priority on the points it covers.

24.4 Subcontractors. We may use subcontractors.

24.5 Invalid clauses. If a clause is invalid, the rest stays in force, and the invalid clause is replaced by a valid one that comes closest to its purpose.

24.6 No waiver. If we do not enforce a right at once, we do not give it up.

24.7 Entire agreement. These Terms, the DPA and the Pricing page are the whole agreement on the Service, unless we sign something else.

24.8 Referrals. If you take part in our referral programme: you may not refer yourself or businesses you control, spam, run paid search ads on our name, use bots or misleading claims, or pretend to be SirenDM; you must label your promotion as an ad where the law requires it; rewards are reversed for refunds, chargebacks or fraud and do not accrue while your account is suspended or closed; and we may change or end the programme, or your participation, at any time. Taking part does not make you our agent, partner or employee.

24.9 Trade usages. Between us as businesses, trade usages do not take priority over these Terms (§ 558(2) Czech Civil Code).
