Veylum
Your words. Yours alone.
What it is
Veylum is an end-to-end encrypted notes app where your text never leaves the device in readable form. It uses the Web Crypto API: a passphrase is stretched with PBKDF2 into a non-extractable AES-256-GCM key, and storage only ever holds ciphertext. It is a from-scratch, dependency-light build where "a wrong passphrase can't decrypt" is a tested invariant, and you can download and run it locally.
Web Crypto E2E: passphrase → PBKDF2 → non-extractable AES-256-GCM; storage holds only ciphertext, and 'a wrong passphrase can't decrypt' is a tested invariant.
