1What is PreceptorOS?

Your AI on your machine, no cloud required. Persistent memory that belongs to you, and a Privacy Gateway that sanitises context before it reaches any external AI. No accounts, no telemetry.

2Your privacy, your control

The filter is the one that crosses out what is private. Paste your context and see what comes out before you hand it to anyone: it happens in your browser, nothing to install, and it also tells you where it does NOT reach.

3Download the app

The web is the shop window. The app is the workshop: that's where the companion you choose works on your real files, without them leaving your machine.

NO_DATA — Android runs through Termux today, following this site's guide; the APK is declared future work and does not exist yet. The desktop installers point at their final address on GitHub Releases and will return 404 until the first version ships. Windows and macOS are NOT tested on this rack: there is no machine of either system here.

4Your pairing code

Your identity is generated in the browser and the private key never leaves it. This pairing code is derived from your public key: always the same for you, and it carries no secret inside.

This code IDENTIFIES you, it does not authenticate you: anyone who knows your public key can compute it. Real linking will also require a signature, and that arrives with the backend.
