Terms of Service

Effective date: August 2, 2026

These terms cover the Casola app and website you use as an individual. If you are a business building on the Casola API, the Developer & API Terms apply to you instead.

Section 12 requires most disputes to go to arbitration and gives up your right to a jury trial and to class actions. You have 30 days to opt out. Read it before you sign up.

1. Who We Are, and Who Can Use This

Casola (“we”, “us”) provides the Service described below. Registered address: 440 N. Wolfe Rd, Sunnyvale, CA 94085. Questions: legal@casola.ai.

You must be 18 or older to create an account or use the Service. There is no version of this Service for children, and we do not knowingly let anyone under 18 use it. If we learn an account belongs to someone under 18, we close it and delete the data.

By creating an account or using the Service you accept these Terms, the Acceptable Use Policy, and the Privacy Policy. If you do not accept them, do not use the Service.

2. What the Service Is

Casola gives you real-time voice conversations with AI avatars: a synthetic face, a synthetic voice, and a character that responds to what you say. The avatars are software. Everything they say is generated, including anything that sounds like memory, feeling, opinion, or advice.

What it is not. The Service is entertainment and general assistance. It is not medical, psychological, legal, or financial advice, and it is not a substitute for professional care, therapy, or a relationship with another person. Do not use it to make decisions about your health, safety, money, or legal position. If an avatar tells you otherwise, the avatar is wrong.

Output can be inaccurate, out of date, or plainly false. Check anything that matters.

3. Subscriptions and Billing

Some parts of the Service are free. Others need a paid plan.

• Plans and prices are shown before you buy, along with the billing period. Prices exclude tax unless stated; tax is added at checkout where it applies.
• Automatic renewal. Paid plans renew automatically at the end of each billing period, at the then-current price for your plan, charged to your payment method, until you cancel. We will tell you the renewal date and amount before your first renewal, and we send a reminder before renewal where the law requires one.
• Cancelling. You can cancel at any time from your account settings, in the same number of steps it took to subscribe and without talking to anyone. Cancellation takes effect at the end of the current billing period. You keep access until then, and you are not charged again.
• Price changes. We tell you before a price change takes effect, and the change applies from your next renewal. If you do not want the new price, cancel before it starts.
• Free trials, where offered, convert to a paid plan at the end of the trial unless you cancel first. We say so at sign-up and tell you when the trial ends.
• Failed payments. If a charge fails we may retry, suspend paid features, or close the plan.

4. Your Right to Cancel (EU, UK, and Similar)

If you live in the EU or the UK, you have a statutory right to withdraw from a purchase of digital services within 14 days, without giving a reason.

By starting a paid plan you ask us to begin supplying it immediately, during the 14-day period, and you acknowledge that once we have fully supplied it you lose the right to withdraw. If you withdraw while we are part-way through supplying it, you pay for what you used up to that point, in proportion to the whole plan.

To withdraw, email legal@casola.ai within 14 days of the purchase, or use the cancellation control in your account settings and tell us you are exercising the withdrawal right. We refund what is due within 14 days of being told, using the payment method you paid with.

Nothing here limits any withdrawal or cancellation right your local law gives you.

5. Refunds

Outside the statutory rights in Section 4, payments are non-refundable, including for periods you did not use. We may still give a refund or credit where something went wrong on our side, at our discretion, and doing so once does not oblige us to do it again.

Your rights under consumer law, including any right to a remedy for a service that is faulty or not as described, are unaffected by this section.

6. Recording

We record your conversations with the avatars. That includes the audio from your microphone, turn by turn, along with video of the avatar’s replies and a recording of the session as a whole.

We use recordings to run and support the Service and to investigate safety problems. We do not sell them and we do not use them to train third-party foundation models. Improving our own avatar and safety models is separate, and uses aggregated, de-identified logs — not your voice or these recordings (Section 3 of the Privacy Policy).

Recordings are deleted automatically 30 days after the session. You can ask us to delete a session’s recordings sooner, or all of them, by writing to privacy@casola.ai, and closing your account deletes them. You can also object to our using your recordings to improve our models, without closing your account — Section 3 of the Privacy Policy explains how.

Section 5 of the Privacy Policy sets out exactly what is captured, why, how long we keep it, and how to have it deleted. Read that section before your first conversation; if you do not want to be recorded, do not start one.

7. Your Content

You can put your own material into the Service: a face image for a custom avatar, a voice sample to clone from, a written brief that gives an avatar its character, scripts, and everything you say in a conversation. All of that is “your content” below.

You keep it. Building an avatar or cloning a voice transfers nothing to us. As between you and us, what you upload stays yours, and so does the avatar or voice you build from it.

What you let us do with it. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, transmit, and display your content, for these purposes and no others:

• running the Service for you, which includes generating an avatar’s speech and video from your material,
• showing your content back to you inside your own account,
• keeping the Service safe and lawful (Sections 9 and 10 of these Terms), and
• the model evaluation and tuning described in Section 3 of the Privacy Policy — which uses de-identified logs, and which you can opt out of in your account settings.

Nothing you make is published. We do not show your avatars, voices, scripts, or conversations to other users, and the licence above gives us no right to. The avatar catalogue we offer publicly is our own; your workspace is yours alone. If we ever want to feature something you made, we will ask, and you can say no.

What you promise us. That you hold the rights to what you upload and that it does not break the Acceptable Use Policy. If it is another person’s face or voice, you need their express, written consent before you upload it.

When the licence ends. It lasts as long as the content is in your account. Delete an avatar, a voice, or your whole account and it ends, apart from backup copies that age out on the schedule in Section 8 of the Privacy Policy and anything we must keep under Section 7 of it.

Removal. We can remove content that breaches these Terms or the AUP. Section 10 says what happens then and how to challenge it.

Feedback is separate. If you send us a suggestion about the Service, we can use it freely, with no obligation and no payment owed to you. That covers ideas about the product. It gives us no further right over your content.

8. Acceptable Use

The Acceptable Use Policy is part of these Terms and binds you directly. It prohibits, among other things, sexual content involving minors, non-consensual intimate imagery, using a real person’s face or voice without their consent, harassment, and content that encourages self-harm.

You are responsible for what you say to the Service and what you do with what it produces. Do not use the Service to break the law or to harm anyone, including yourself.

9. Safety

The avatars are not a crisis service and cannot help in an emergency.

If you are in danger or thinking about harming yourself, contact your local emergency number. In the US, call or text 988 for the Suicide & Crisis Lifeline. In the UK, call 116 123 for Samaritans. A list of international helplines is at findahelpline.com.

We would rather be exact than reassuring: the Service is not a crisis, emergency, or mental-health service, and you must not rely on it as one. An avatar is a language model holding a conversation. If you are at risk, use the numbers above.

Do not rely on the Service for medical, mental-health, legal, or financial decisions. See Section 2.

10. Suspension, Termination, and Appeals

You can close your account at any time from your account settings. Closing it deletes your recordings and the rest of your data as described in Section 9 of the Privacy Policy. Cancelling a paid plan does not close your account, and closing your account does not by itself refund the current period.

We may suspend or close your account if you breach these Terms or the AUP, if we are required to by law, or if keeping it open would create a security or safety risk. Where a violation is severe, including the absolute prohibitions in the AUP, we act immediately and without notice. Otherwise we give you notice and, where it is appropriate, a chance to put it right.

If we close your account without cause, we refund the unused part of any prepaid period.

If we act against you, you can challenge it

We tell you why. When we suspend or close your account, or remove something you made, we send you the reason, what we acted on, whether a person or an automated check flagged it, and how to challenge it. The one exception is where telling you would itself break the law, which in practice means an active law-enforcement matter.

You can appeal. Email legal@casola.ai with “Appeal” in the subject, the address on your account, and anything you want us to weigh. No form and no fee.

If we got it wrong, we undo it. We reinstate the account, restore the content, or both.

What we will not put back. Where we have reported material to NCMEC or another authority under Section 7 of the Privacy Policy, the material and the account stay down. You can still appeal and we still answer, but that duty is not ours to set aside.

If you are in the EU: this is our internal complaint-handling process. Nothing in it stops you from taking the dispute to court, or to any dispute-resolution body available to you under your local law, and appealing to us first does not affect that.

11. Disclaimers and Liability

Nothing in these Terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, for fraud, or under any non-excludable consumer guarantee. If you are a consumer in the EU, the UK, or another place with mandatory consumer protection, this section applies only so far as your local law permits, and your statutory rights come first.

Subject to that:

• We provide the Service with reasonable care and skill, but we do not promise it will be uninterrupted, error-free, or that its output will be accurate or suitable for a particular purpose.
• We are not liable for losses that were not reasonably foreseeable when you accepted these Terms, or for loss arising from your using the Service in a way it is plainly not meant for (see Section 2).
• Where liability can lawfully be capped, our total liability to you for any claim is limited to the greater of the amount you paid us in the 12 months before the claim and USD 100.

12. Disputes

Please email legal@casola.ai first. Most problems are resolved this way. Both of us agree to try for 30 days before starting formal proceedings.

Arbitration. If that does not work, and unless an exception below applies, you and we agree that any dispute will be resolved by binding individual arbitration administered by JAMS under its Consumer Arbitration Minimum Standards and applicable rules, seated in Santa Clara County, California, or in your home county if you prefer. Arbitration means a single arbitrator, not a judge or jury. Where JAMS rules make us responsible for the filing fee, we pay it.

Class-action waiver. Claims are brought individually. Neither of us may bring a class, collective, or representative action, and the arbitrator may not consolidate claims without both parties’ agreement. If this waiver is held unenforceable for a particular claim, that claim goes to court and the rest of this section still applies to the others.

How to opt out. You can opt out of arbitration and the class-action waiver by emailing legal@casola.ai with the subject line “Arbitration opt-out” within 30 days of first accepting these Terms. Include the email address on your account. Opting out costs you nothing and affects nothing else in these Terms.

Small claims. Either of us may bring a qualifying claim in small-claims court instead of arbitration.

Coordinated filings. If 25 or more similar claims are filed against us by or with the help of the same counsel, JAMS’ mass-arbitration procedures apply, and both sides agree to the staged process and fee schedule set out in them.

Governing law and forum. These Terms are governed by the law of the State of California, without regard to conflict-of-law rules, and the courts of Santa Clara County have jurisdiction over anything not sent to arbitration.

If you are a consumer in the EU or the UK: none of the above takes away the protection of the mandatory law of the country you live in, or your right to bring proceedings in your local courts. EU consumers can also use the European Commission’s online dispute resolution platform.

13. Changes and Contact

We may change these Terms. For material changes we give notice by email and in the app before they take effect, and the change applies from the date stated in that notice. If you do not accept a change, cancel before it takes effect. Continuing to use the Service after that date means you accept the new terms.
