Z-Text holds your keys and your messages, so the app you install matters. Copies on other websites or third-party APK mirrors can be altered to steal funds or read your chats — the only safe sources are this site and the official app stores (Apple App Store and Google Play) once the apps land there.

A direct download here is the safest, cleanest option: every build is signed by our CI pipeline, and you can confirm the SHA-256 checksum shown on each file below.

Could not load downloads. Please try again shortly.

Builds are produced by GitHub Actions and uploaded directly to this site. Each download lists its SHA-256 checksum above — after downloading, run sha256sum (or shasum -a 256) on the file and confirm it matches.
