Secure Email by UZYTAK — privacy policy

Updated 13 November 2026

In short

The app connects directly from your phone or computer to your mail servers (IMAP/SMTP). We do not read, collect, store or sell your mail, contacts or passwords. There is no UZYTAK server for your mail, no ads and no advertising identifiers.

What stays on your phone

Mailbox settings, a cache of your letters and the search index stay inside the app on your phone. Saved letters are encrypted with AES-256-GCM and the database with SQLCipher; the key is kept in the Android Keystore. Mailbox passwords are kept in the Android Keystore. The app's data is excluded from phone backups and device transfer.

What reaches the internet

Your mail servers, over encrypted connections (SSL/TLS), to fetch and send your mail. Pictures from the internet in letters load only when you allow it. Purchases of Pro are handled by Google Play or the Microsoft Store. If you type a partner code, it is checked on partners.uzytak.com. If you buy Pro with a partner code, the code and the store's purchase number (no name, no e-mail) are sent to partners.uzytak.com so the partner gets paid.

On Windows

The Windows version can keep an archive of your letters as ordinary .eml files in a folder you choose on your computer (on Windows the archive and the mail cache are not encrypted, so protect that folder like any other documents). Its optional AI helpers run on your own computer (a local model at 127.0.0.1) — nothing is sent outside.

Protection settings

You can lock the app with fingerprint, face or PIN and hide it from screenshots and the recent-apps preview. While the lock is on, notifications show only the number of unread letters per mailbox.

Your rights

Everything the app stores is on your phone: uninstalling the app deletes it. For questions write to support@uzytak.com.
