Tuga's GPG Tool

Lock it. Send it. Sleep.

In a world where your toaster has a privacy policy, your TV watches you back, and "free" apps quietly sell your soul in 14 languages, GPG Tool does something genuinely radical: nothing with your data. No accounts. No cloud. No "we care about your privacy" email that somehow proves the opposite. Just you, your file, a password, and math that not even we can undo. Security stopped being optional somewhere around the time your fridge got Wi-Fi — this is the boring, bulletproof basic everyone should already have.

The human explanation

Pick a file. Pick a password. Tap Encrypt. Your file becomes a wall of unreadable gibberish that only your password can open. Email it, back it up, leave your phone in a taxi — doesn't matter. Without the password, it's noise to thieves, snoops, carriers, and cloud providers alike. Forget the password, and, fair warning, it's noise to you too. There's no "reset password" link, no support line, no backdoor. That's not a missing feature — that's the entire point. The whole app has three buttons. Your grandmother could use it; your adversaries can't.

The spec-sheet explanation

For those who read the cryptography before the reviews: GPG Tool uses AES-256 in OpenPGP's symmetric mode with an integrity-protection packet, so tampering gets caught, not silently passed through. Your passphrase is run through a salted, iterated key-derivation function — no raw passwords touching keys. Output is bit-for-bit compatible with the gpg command line, so you can encrypt here and gpg -d it on a server, or vice versa. There is zero network code in the app. No analytics SDKs, no trackers, no telemetry, and on modern Android it doesn't even request storage permission — it works entirely through the system file picker. The app couldn't phone home if it wanted to, because nothing inside it knows how to dial.

The part where you tap Install

GPG Tool is, and always will be, 100% free — no ads, no "pro" tier, no premium unlock holding your privacy hostage. It's also fully open source: read every line, compile it yourself, trust but verify. And it doesn't stop at your phone. Get it for Windows (7 and up), Linux (.deb), and even older Android devices — same simple app, same strong crypto, everywhere you keep things that matter.

Every version, plus the complete source code, lives at darthtuga.com/gpg — free forever.

Encrypt like nobody's watching. With this app, nobody is.
