the secret-letter app encrypts your message and decrypts encrypted text back.
The encrypted message is destroyed after a day. This ensures that your message stays safe.
The Encryption algorithm (Latest KI algorithm) encrypts the text offline. No data is stored on the server. No internet connection is required.
Share your three-digit PIN with someone with whom you want to exchange encrypted messages.
The app shows you the remaining time when the encryption changes itself and becomes unusable.
You can copy the encrypted text or send directly to someone, using whatsapp, email, sms, mms, clipboard etc.
Its easy, fast and save. Try it.
