Terms of Service

Last updated: November 12, 2026

Welcome to Aster. These terms govern your use of the Aster personal assistant — a beta product that works through Telegram and this website. By requesting access, signing up, or chatting with the assistant, you agree to them.

1. What Aster is

Aster is an AI-powered personal assistant. It can hold conversations, remember preferences, manage reminders and tasks, search the web, work with your connected email and calendars, prepare purchases, and place phone calls on your behalf. It is software, not a human, and it may be wrong. Do not rely on it for medical, legal, financial or safety-critical advice.

2. Agent authority

Aster acts on your behalf only within limits you set. Actions with external effects — sending email, writing to your calendar, making a purchase, placing a phone call — are presented to you for approval first. By approving an action, you authorize Aster to perform it as your agent and you are responsible for its consequences, including any commitments, reservations or purchases made in your name. Review approval details carefully; what you approve is what happens.

Draft emails, memories, reminders and tasks are internal actions and do not require approval.

3. Purchases and payments

• Payments are processed by Stripe. Saving a card stores a reference with Stripe; Aster never holds your full card number.
• Charges occur only after you approve a specific purchase. Saved cards may be charged off-session at the moment you approve, or you may complete a checkout link yourself.
• When Aster or its fulfillment partner completes a booking on a third-party site, the transaction is with that vendor under their terms. Their cancellation, refund and change policies apply.
• If a fulfillment attempt fails after payment, contact us and we will refund or release the charge.

4. Phone calls

Calls are placed through telephony providers (Twilio). Aster identifies itself as an AI assistant calling on your behalf at the start of every call. You are responsible for ensuring calls you request are lawful in your jurisdiction, including call-recording consent rules.

5. Connected accounts

Connecting Google, Microsoft or iCloud grants Aster the access shown on the provider's consent screen. Tokens are stored encrypted. You can disconnect any provider in the dashboard or revoke access from the provider's side at any time.

6. Acceptable use

You agree not to use Aster to break the law, spam, harass, defraud, violate third-party terms, attempt prompt-injection or abuse of the service, or have it contact people who did not consent. We may suspend or terminate accounts that abuse the service.

7. Beta status and availability

Aster is a beta. Features may change or break, uptime is best-effort, and third-party bookings, calls and purchases may fail. We do not guarantee any particular outcome — a failed reservation or purchase attempt will be reported honestly, not concealed.

8. Your data

Your data is governed by our Privacy Policy. You can export or delete everything from the dashboard at any time.

9. Disclaimers and liability

The service is provided as is, without warranties of any kind. To the fullest extent permitted by law, we are not liable for indirect, incidental or consequential damages, or for losses exceeding the fees you paid us in the three months before the claim. Nothing in these terms limits liability that cannot be limited by law.

10. Changes

We may update these terms as the product evolves; material changes will be posted here with a new date. Continued use after changes means acceptance.

11. Contact
