Rune

Rune is a calm, fast notes app for people who don't want to trust an app with

their data. Your notes never leave your device, they are encrypted at rest, and

the app makes no network connections at all. There is no account, no cloud, and

no sign-up.

Privacy by construction, not by promise:

* No telemetry, no analytics, no crash reporting, no advertising, no tracking —

none, not "anonymised", not "aggregated".

* No networking code. Put your device in airplane mode and everything still

works. If anything ever tries to reach the network, that is a bug.

* No account and no server. There is no "we" that could hold your data.

Real encryption:

* Your passphrase derives a key with Argon2id; notes are sealed with

XChaCha20-Poly1305 authenticated encryption. Only ciphertext is ever written

to disk.

* The passphrase is never stored and is not recoverable. If you forget it, your

notes are gone — no reset, no backdoor. That is the price of real privacy.

* A wrong passphrase simply cannot decrypt your notes.

What you can do:

* Create, edit, search, and organise plain-text notes with an Apple-Notes-style

layout that adapts from phone to desktop.
