Tuga's GPG Encryption — a circuit-shell turtle guarding a padlock

Tuga's GPG Encryption Your files, sealed in the shell.

Offline file encryption with AES-256. No accounts, no cloud, no nonsense — just you, a password, and a very private turtle. The whole app is three buttons.

No internet No ads No tracking AES-256 Open source 100% free
Three taps

Slow is smooth. Smooth is secure.

1

Pick a file

Any file, any size. Photos, documents, that folder you don't talk about.

2

Set a password

A strength meter nudges you away from "password123." Choose something only you know.

3

Encrypt

Out comes a sealed .gpg file. Unreadable to everyone without the password — including us.

Two Android builds, nobody left behind. The newest build targets modern Android (8.0 through 16) and is live on Google Play. The legacy build still runs on a 2013 phone on Jelly Bean. Source for both is right here.
🍎 No iOS build — and that's on purpose. Apple's walled garden decides what's allowed on your iPhone; you don't. A tool built around you owning your keys doesn't fit a platform built on asking permission. The turtle prefers to roam where it's free.
No catch

Why you can actually trust it

It's open source. Every line is readable. Don't trust a security app you can't inspect — so inspect this one, or build it yourself from the source above.

It can't phone home. There's no network code in it. No analytics, no trackers, no "anonymous usage data." The app literally doesn't know how to reach the internet.

It's real cryptography. AES-256 in OpenPGP's symmetric mode with integrity protection. Output is compatible with the gpg command line — encrypt here, decrypt anywhere, or the other way around.
