Privacy Policy

Grimeton for iPhone, iPad and Mac · Last updated November 10, 2026

In short: Grimeton collects no data. We have no servers, no accounts, no analytics and no ads. Your Mac's screen, sound, microphone and camera travel directly between your own devices.

Who we are

Grimeton is published by Orichalque SAS, 26 rue Bosquet, 75007 Paris, France (RCS Paris 983 937 731). Contact: support@grimeton.app.

What goes where

• Screen, sound, keyboard, trackpad, microphone and camera. They are streamed directly between your Mac and your iPhone or iPad, over your own Tailscale network, encrypted end to end by Tailscale. They never go through a Grimeton server, and nothing is recorded.
• Microphone and camera. The iPhone or iPad turns them on only while an app on your Mac is using the Grimeton Microphone or Grimeton Camera, and you can switch them off at any time in the app.
• Your list of Macs. Each Mac publishes its name, network address and a public key to your private iCloud database, so that your iPhone and iPad find it. This data stays in your iCloud account; we cannot read it.
• Pairing codes and keys stay on your devices, in the system keychain.
• Donations. Grimeton is free. If you choose to leave a donation, it is handled by Apple through the App Store. We receive no payment or personal information, and a donation unlocks nothing.
• Connections. The Mac only accepts connections that come through your Tailscale network.

What we don't do

We do not collect, store, sell or share personal data. There is no tracking, no advertising, no third-party analytics and no crash reporting beyond what you choose to share with Apple.

Third parties

Grimeton relies on services you use under your own accounts: Apple (iCloud, App Store) and Tailscale, which connects your devices. Their own privacy policies apply to them. The grimeton.app website is hosted by Cloudflare, which may keep standard technical logs; the website uses no cookies.

Children

Grimeton is not directed at children and collects no data from anyone.

Your rights

Because we hold no personal data, there is nothing for us to access, correct or delete. You can remove a Mac with "Forget this Mac" in the app, or remove Grimeton's data from iCloud in your device's settings. For any question, write to support@grimeton.app. You may also contact the French data protection authority (CNIL).

Changes

If this policy changes, the new version will be published on this page with a new date.
