BOB Chat — Privacy Policy

Last updated: 2 June 2026

BOB Chat ("the app", "we", "us") is an Android Telegram client with an on-device AI assistant, published by Bob Tools LLP. This policy explains what data the app handles and how. The guiding principle is simple: your Telegram messages and contacts are never stored on our servers.

What we collect

• Email address — when you sign in to your bob.tools account (used to identify your account and manage your subscription). This is the only personal identifier we store on our servers.

What stays on your device

• Your Telegram data — chats, messages, contacts and media are handled directly between your device and Telegram's servers (via TDLib). We do not receive, store, or proxy this content on our servers.
• AI processing — reply suggestions, summaries and task extraction run on-device through BOB Brain. The content of your messages is not sent to us for these features.
• On-device databases — tasks, contact notes and the local search index live only in the app's private storage on your device.

Subscriptions and payments

Paid subscriptions are processed by Google Play Billing (in-app) or by Stripe (on the web). We do not receive or store your full card details; payment processing is handled by those providers under their own privacy policies.

How we use your email

To create and authenticate your account, to associate your subscription entitlement, and to contact you about your account if needed. We do not sell your data, and we do not share it with third parties except the service providers needed to run the service (e.g. Google Firebase for authentication, Stripe for web payments). Data is encrypted in transit.

Data retention and deletion

You can request deletion of your account and associated email at any time by contacting us at the address below. Telegram content is not stored by us, so there is nothing for us to delete on that front — managing your Telegram data is done through Telegram itself.

Children

BOB Chat is not directed at children and is intended for adults.

Changes

We may update this policy; material changes will be reflected on this page with a new "Last updated" date.
