Privacy Policy.

UIMessage is an end-to-end encrypted messenger. Your one-to-one and group messages, calls, status updates, and media are encrypted on your device and can only be read by you and the people you send them to. We do not have the keys, so we cannot read your conversations — and we never sell your data or show you ads.

Account information: your phone number, which we use to create your account and help your contacts find you. You may optionally add a display name, profile photo, and an “about” line.

Contacts: if you grant permission, we use your address book to show you which of your contacts already use UIMessage. Contact matching is performed using transformed (hashed) identifiers wherever possible.

Technical and delivery data: limited metadata required to deliver messages and calls (such as device tokens for notifications, timestamps, and routing information). We minimize and retain this for only as long as needed to operate the service.

Because UIMessage uses end-to-end encryption by default, we cannot read the content of your messages, listen to your calls, or view your media and status updates. Encryption keys are generated and stored on your devices, never on our servers in a form we can use to decrypt your content.

We use the limited information we collect to operate, maintain, and secure the service: registering your account, delivering messages and notifications, connecting calls, preventing abuse and spam, and improving reliability and performance.

We do not use your information for advertising, and we do not sell or rent it to third parties.

We share information only with service providers who help us run UIMessage (for example, push-notification delivery), under contracts that require them to protect it, or when required by law. We will always seek to limit any disclosure to the minimum necessary.

Encrypted messages are stored only as needed to deliver them to your devices and are removed from our servers once delivered. Account information is retained while your account is active. When you delete your account, we delete the associated account data and your conversations stop being reachable on our systems.

You can edit your profile, manage privacy settings (such as who can see your profile photo, last-seen, and status), and delete your account at any time from within the app. You can also revoke contacts, notifications, camera, and microphone permissions in your device settings.

UIMessage is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect information from children below that age.

We may update this policy from time to time. When we make material changes, we'll update the date above and, where appropriate, notify you in the app.

UIMessage is built by Silicon Visions. If you have questions about this policy or your data, reach us at privacy@uimessage.com.
