This website and app allow you to encrypt and decrypt text directly in your browser or on your device – no server, no tracking, completely local. You enter a text, we generate a random key, and encrypt it using the modern AES-GCM algorithm.
AES-GCM stands for Advanced Encryption Standard – Galois/Counter Mode. It is a highly secure method that not only encrypts the content but also protects its integrity. This means: any manipulation of the encrypted text is detected and blocked.
Every encryption needs a key. We generate a unique, random key for each message. This key is part of your link and is never stored on our server – it only exists in the URL you share.
Once the encrypted message is viewed, it is permanently deleted from the server. There is no "read again" – the data is gone. This ensures maximum privacy.
We don't log who encrypts what, we don't track IPs, and we don't analyze usage patterns. The only thing we save temporarily is the encrypted text – and that's deleted after the first view.
