The mechanics of private text storage, explained plainly.
TextSafe stores encrypted text that only you can read. The encryption key is created from two things you provide:
Together, these form the key to your locker. Without both pieces, the content is unreadable.
Type or paste your text into the editor. Format it if you like-bold, lists, links all work.
Click "Save" and choose a security color. This color is part of your encryption key.
Pick how long to store: 2 days, 7 days, or 30 days. Data is deleted after expiration.
Note your access code and color. You will need both to retrieve your text.
From any device:
Important: The server never sees your passcode or color. It only stores encrypted data. If you forget either credential, your data cannot be recovered.
Encryption: AES-256-GCM (Galois/Counter Mode)
Key Derivation: Argon2id (memory-hard, GPU-resistant) with 64MB memory cost
Storage ID: SHA-256 hash of the derived key (we never see your credentials)
All encryption happens in your browser. The server stores only ciphertext.
