About this app

🔐 Secure Text — 100% offline. 100% secure.
Truly offline AES-256 encryption.
Everything runs locally on your device — no internet, no server, no accounts, no tracking. Your data never leaves your phone.

Why it's secure: No network needed, works anywhere; no cloud storage, nothing uploaded; no sign-up or tracking; zero data collection.

How to use: Paste or type any text, set a password, encrypt to get an unreadable cipher string, share it through any app, and only someone with the password can decrypt it.

Under the hood: AES-256-CBC encryption with PBKDF2 (65,536 iterations), random salt and IV per encryption, and self-contained Base64 output.

Use it for: Sending sensitive messages, storing private notes, sharing credentials, or keeping personal writings private.

🌍 Available in 15 languages — English, Spanish, Portuguese, German, French, Japanese, Korean, Italian, Simplified Chinese, Traditional Chinese, Turkish, Hindi, Indonesian, Vietnamese, and Thai.
