BOB Chat — Privacy Policy

Last updated: 27 July 2026

BOB Chat ("the app", "we", "us") is a Telegram client for mobile devices (Android and iOS) 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, and never leave your device for AI features unless you explicitly choose the cloud model.

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, except transiently when you invoke the optional cloud AI model (see below).
• AI processing (on-device model) — when you use the on-device model, reply suggestions and summaries run locally through BOB Brain, and the content of your messages is not sent to us for these features. If you choose the optional cloud AI model, the messages needed to answer that request are sent to our servers (and on to our AI provider) to generate the response; they are processed to generate that response and are not stored by us. Our AI provider may retain API logs for a limited period for abuse monitoring under its API terms.
• On-device databases — AI chat history, AI memory and local caches live only in the app's private storage on your device.

Subscriptions and payments

Paid subscriptions are processed by Google Play Billing (in-app on Android), Apple In-App Purchase (in-app on iOS), 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. In-app subscriptions auto-renew and can be managed or cancelled in your Google Play or App Store account settings.

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

We keep your email address for as long as your bob.tools account exists, and delete it on request. 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.

Your rights

Bob Tools LLP (England and Wales) is the data controller. Depending on your jurisdiction (including under the UK and EU GDPR), you may have the right to access, correct, delete, or restrict the use of personal information we hold about you, and to lodge a complaint with the ICO or your local supervisory authority. Our service providers (e.g. Google Firebase, our AI provider) may process data in countries outside your country of residence, under the safeguards those providers maintain.

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.
