Terms of Service

Last updated: October 9, 2026.

1. Acceptance

These Terms are an agreement between you and Sybo.ai ("Sybo", "we", "us"). They cover the Sybo.ai apps, sybo.ai and app.sybo.ai. Our Privacy Policy is part of these Terms. You accept these Terms when you create an account, continue as a guest, or use Sybo. If you do not agree, do not use Sybo.

2. Eligibility and accounts

  • You must be at least 18 years old and able to enter a binding contract.
  • You can sign in with email or phone (using a one-time code), Apple, Google or Facebook. You can also try Sybo as a guest. Guest accounts have limited features, such as no Memory, no Topic Agents and limited free time. Guest data may be lost if you don't sign up.
  • Keep your login secure. You are responsible for everything done through your account. Tell us at support@sybo.ai if you think someone else has used it.
  • One person per account. Do not create accounts to get extra free trials or credits.

3. Using Sybo

Sybo lets you talk with AI companions and Topic Agents by text, voice, and live video avatar. You can create personal avatars and cloned voices, upload files, generate images and documents, and let Sybo remember your preferences with Memory.

AI output can be wrong. Replies are generated by AI. They may be inaccurate, incomplete, out of date, or made up, and web search results may come from unreliable sources. Topic Agents are AI personas, not doctors, lawyers, financial advisers or therapists. Nothing Sybo says is professional advice. Check anything important with a qualified person. In an emergency, contact local emergency services.

AI companions are not people. Sybo's companions and avatars are AI. They have no feelings, and any persona is fictional.

The service changes. We may add, change or remove features, agents, avatars and AI models. We may also set fair-use limits, for example on how many avatars you can generate.

4. Subscriptions and billing

  • Where you pay. On iOS, you pay through Apple In-App Purchase. On Android, you pay by card through Stripe. Store purchases also follow Apple's or Google's terms.
  • Card payments. Stripe processes card payments, including 3-D Secure checks, and stores your card details. We never receive your full card number. You authorise Stripe to charge your payment method for your plan, renewals and top-ups.
  • Prices. Prices, taxes and what each plan includes are shown before you pay and may differ by platform and country. If a price changes, we tell you before your next renewal.
  • Invoices. You can download invoices in the app.
  • Refunds. Refunds for App Store purchases follow Apple's policy. For Stripe purchases, contact support@sybo.ai. We give refunds where the law requires it or where the plan says so.

5. Auto-renewal and cancellation

Subscriptions renew automatically, monthly or yearly, until you cancel. By subscribing, you agree to these recurring charges.

  • When we charge. Each renewal is charged up to 24 hours before the current period ends, at the plan's current price.
  • How to cancel.
    • iOS: Settings › your name › Subscriptions.
    • Android: Google Play › Payments & subscriptions, or in the Sybo app for Stripe plans.
    • Deleting the app, or deleting your Sybo account, does not cancel a subscription.
  • Deadline. Cancel at least 24 hours before the period ends to avoid the next charge.
  • After you cancel. You keep paid features until the end of the period you paid for. Then your account moves to the free plan, and text chat stays free.
  • Upgrades. An upgrade takes effect as soon as payment goes through. Apple or Stripe works out any proration. You get the new plan's credits and features straight away.
  • Downgrades. A downgrade takes effect at the end of your current billing period. There is no charge when you request it.
  • Same platform. You can change or cancel a plan only on the platform where you bought it (Apple or Stripe).
  • Free trials and introductory offers. The length and price are shown at checkout. When the trial ends, it becomes a paid subscription unless you cancel at least 24 hours before. Each person can use only one trial or introductory offer.
  • Failed payments. If a renewal payment fails, we may try again and pause paid features until it succeeds. If payment keeps failing, the subscription ends.
  • Refunds on renewal. Cancelling stops future charges. It does not refund a charge already made, unless the law requires it.

6. Credits

Sybo uses credits, not minutes. Each paid plan includes a monthly allowance. Yearly plans include the same monthly allowance each month.

The monthly allowances are:

  • Starter: 1,000 credits per month
  • Plus: 2,200 credits per month
  • Pro: 5,000 credits per month

What uses credits:

  • voice sessions, per minute;
  • avatar sessions, per minute (standard or premium quality);
  • creating a personal avatar (one-time);
  • cloning a voice (one-time);
  • image generation;
  • document processing, extra document questions, and document generation.
  • What is free. Text chat is free. Any free avatar seconds included with your plan are used before credits.
  • Prices. The current credit cost of each feature is shown in the app under My Credits › How credits work. We may change these costs, and we show the change in the app before it takes effect.
  • Monthly reset. Plan credits reset at the start of each billing period. Unused plan credits do not carry over.
  • Top-ups. You can buy extra credits as a one-time purchase that does not renew. Top-up credits are used only after your plan credits run out, and they do not expire while your account exists.
  • If your subscription ends. Your remaining credits are kept and become usable again if you resubscribe.
  • Running out. When you run out of credits, paid features pause until your next renewal, a top-up or an upgrade. Text chat keeps working. File uploads may also be refused if you have no credits or your storage is full.
  • Credits are not money. Credits are a licence to use features. They have no cash value, cannot be transferred, sold or exchanged, and are not refunded, except where the law requires it.
  • Failed sessions. If a session fails because of a problem on our side, contact support. We will review it and may give back the credits. If image generation fails, the credits are returned automatically. This is your only remedy for credits lost to faults or outages.
  • Misuse. We may remove credits gained through bugs, promotion abuse, chargebacks, multiple accounts, or automated use. If we close your account for breaking these Terms, you lose your credits without a refund.

7. Voice cloning

Voice cloning is optional. It builds a private voice model from a recording you make in the app or a file you upload, so your avatar can speak in that voice. Before cloning, you must tick the consent box. By doing so you promise that:

  • the voice is yours, or you have clear, provable permission from the person recorded;
  • the recording is not of a child, a celebrity or public figure, a performer, a person who has died, or anyone who has not agreed;
  • you will not use the cloned voice for impersonation, fraud, scam calls, or audio that passes itself off as a real recording;
  • you understand the cloned voice is synthetic and may not sound exactly like the original.

You give us a limited, revocable licence to process the recording and voice model only to provide this feature to you. Delete the voice at any time from the avatar screen, and the licence ends. We may delete a voice that we reasonably believe was created without permission. See our Privacy Policy for how voice data is handled.

8. Avatars and facial data

You can pick an avatar from our library, describe one in words, or create a personal avatar ("AI Twin") from a photo.

  • Photos. Upload only your own face, or one you have clear permission to use. Never upload a photo of a child, a celebrity or public figure, or a stranger. You must tick the consent box before we process a photo.
  • Safety checks. We check every photo and description automatically. We may reject one that has no clear face, shows explicit or harmful content, appears to show a public figure, or does not meet our guidelines. If we reject your upload, we tell you why. If you think we got it wrong, contact support@sybo.ai.
  • Text descriptions. Describe only a fictional, respectful, safe-for-work adult portrait. Do not try to recreate a real person.
  • Licence. You give us a limited, revocable licence to process the photo and the avatar created from it, only to provide this feature to you. Delete the avatar from your profile and the licence ends.
  • Our rights. We may remove an avatar that we reasonably believe uses someone's likeness without permission. Repeated misuse ends your account.

See our Privacy Policy for how facial data is handled.

9. AI video

Avatar mode creates live AI video of an avatar speaking in real time. Sybo may also create a short intro video that you can save or share.

  • Rights you need. Every face and voice in your videos must be yours, or one you have permission to use. Video is the easiest format to mistake for a real recording, so section 10 applies to it in full.
  • Using your videos. As long as you follow these Terms and pay what you owe, you may use, download and share videos Sybo makes for you, including for commercial purposes. We do not claim ownership of them.
  • Labelling. When you share AI video publicly, you must say it is AI-generated wherever the law or the platform requires it. Do not remove, hide or falsify any AI label on your videos.
  • No guarantee of quality. Videos may have visual glitches, imperfect lip-sync, or wrong speech. Quality depends on your photo, your network and our providers. Sessions may end early.
  • Not a real event. AI video shows something that never happened. Never present it as evidence, news, or a genuine recording of anyone.

10. Impersonation and deepfakes: zero tolerance

Never use another person's face or voice without their permission. This is the rule we enforce most strictly. You must not use Sybo to:

  • clone a voice, or build an avatar from a face, of anyone who has not agreed (friends, colleagues, celebrities, politicians, performers, or people who have died);
  • create any face or voice content of a child;
  • impersonate a real person or organisation, or make content suggesting someone said or did something they didn't;
  • present synthetic audio or video as a real recording, or remove or fake AI labels;
  • create sexual, intimate, defamatory, harassing, or politically misleading content about a real person;
  • use a generated likeness for fraud or scams, or to suggest someone endorses something.

A first breach is enough for us to remove the content, delete the voice or avatar, and permanently ban the account without notice or refund. We cooperate with lawful requests from the person whose likeness was misused and from law enforcement.

Report misuse. If someone has used your face or voice on Sybo without permission, email legal@sybo.ai. You can also report any message in a chat. We act on reports promptly.

11. Your content and AI output

You keep the rights you already have in what you submit: messages, photos, audio and files. You give Sybo a worldwide, non-exclusive, royalty-free licence to host, store, send and process that content, only to run Sybo for you. That includes generating replies, building avatars and voices, reading your files, and saving Memory if it is on. The licence ends when you delete the content or your account, apart from backups on their normal cycle.

As long as you follow these Terms and pay what you owe, you may use the text, images, documents, audio and video Sybo generates for you, including for commercial purposes. AI output is not unique, so other users may get similar results. You are responsible for making sure your use is lawful.

12. Sharing and your responsibility

You can save media to your device or share it through other apps. Shared avatar videos get a link that anyone with the link can open.

  • You are solely responsible for what you generate, download, post or share.
  • You confirm you have the rights to every face, voice, image and piece of text you share.
  • You must follow the rules of the platform you post to, including any AI-labelling rules.
  • We do not review or endorse what you share, and it does not represent our views.
  • We are not liable for any claim, loss, reputational harm, takedown or legal consequence arising from media you chose to share. You will cover our costs if anyone affected by it brings a claim against us.
  • Deleting something in Sybo cannot remove copies already shared elsewhere.

13. Acceptable use

You must not:

  • use Sybo for anything unlawful, harmful, harassing, hateful, or abusive;
  • upload faces, voices, files or content you don't have the right to use;
  • create sexual content involving minors, non-consensual intimate images, or deceptive deepfakes;
  • use Sybo to plan or carry out self-harm, violence, weapons, or other dangerous acts;
  • rely on Sybo instead of professional medical, legal, financial, or mental-health help;
  • probe, scrape, reverse engineer, or get around security controls, credit limits, free-trial limits or App Check, or extract API keys from the app;
  • resell, sublicense, or use Sybo or its output to build a competing model or dataset;
  • use bots or automated scripts, or open multiple accounts to get around limits.

14. Data and deletion

Our Privacy Policy explains how we collect, use, store and keep your data. In the app you can delete conversations, Memory, files in Storage, cloned voices, avatars, or your whole account. We process deletions within 30 days, and backups are overwritten within a further 30 days. We keep some records, such as invoices, where the law requires it. Deleting your account does not cancel a store or Stripe subscription.

15. Third-party services and uptime

Sybo relies on other companies, including AI model, speech, voice and video providers, LiveKit, Firebase, Stripe, Apple, Google, Meta, AppsFlyer and Smartlook. Their own terms cover their services.

Sybo is provided "as available". Voice, avatar and video depend on AI servers and networks we don't own. We are not responsible when a provider is slow, limited, changed, discontinued or down. We are also not responsible for problems caused by your network, your device, maintenance, or anything else beyond our reasonable control. We may change or replace the AI models behind Sybo, and this can change how replies sound or behave. If an outage stops you using a paid feature for a long time, contact support. We may restore the affected credits, and that is your only remedy for downtime.

16. Our intellectual property

Sybo, its software, avatar library, agents, designs and brand belong to us or our licensors. We give you a personal, non-transferable, revocable licence to use the app under these Terms. All other rights are reserved. We may use any feedback you give us without owing you anything.

17. Removing content, bans and termination

You can stop using Sybo or delete your account at any time.

If you break these Terms, depending on how serious it is and your history, we may:

  • remove content;
  • delete a voice or avatar;
  • restrict features;
  • suspend your account;
  • permanently ban you, including blocking your devices and payment methods.

Impersonation, deepfakes, content involving minors, and illegal activity lead to an immediate permanent ban. We may also suspend access when the law requires it, to protect people, or if you don't pay. Where we can, we will explain why. For smaller breaches, we will give you a chance to fix the problem. You can appeal any decision at legal@sybo.ai.

We don't refund fees or credits when we close an account for a breach. Some sections continue to apply after termination: licences already granted, your responsibility for shared media, disclaimers, limits on liability, your obligation to cover our costs (indemnity), and governing law.

18. Disclaimers and limitation of liability

Sybo is provided "as is" and "as available", without warranties of any kind. This includes warranties of accuracy, fitness for a purpose, non-infringement, and availability of AI output. As far as the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, data or goodwill. Our total liability is limited to the greater of what you paid us in the 12 months before the claim, or USD 50. Some places don't allow these limits, and nothing here limits liability that cannot legally be limited.

You agree to cover our costs and losses from claims caused by your content, your use of Sybo, or your breach of these Terms. This especially includes claims that you used a voice or likeness without permission.

19. Changes and governing law

We may update these Terms. If a change is significant, we will tell you in the app or by email before it takes effect, and continuing to use Sybo means you accept it. These Terms are governed by the laws of the country where Sybo.ai is established, and disputes go to the courts of that country. This does not take away the mandatory consumer rights you have in the country where you live, including the right to bring a claim in your local courts.

20. Contact

For questions about these Terms, or to report misuse of a face or voice, email legal@sybo.ai. For privacy questions, email privacy@sybo.ai. For help with the app, email support@sybo.ai.
