tn07 is the publisher name for a set of personal software projects, including Switchboard. They are built and maintained by one person. There is no company, no analytics, and no advertising.

The short version

These apps run on your own devices and talk to your own machines. No server operated by tn07 receives your data, because there is no such server.

Google sign-in and the data it touches

The Switchboard mobile app can sign in with Google. When it does, it requests these OAuth scopes:

• https://www.googleapis.com/auth/cloud-platform - used solely to open Google Cloud IAP tunnels to Compute Engine instances you already have access to, so the app can reach your own development machines without a VPN.
• openid and email - used solely to display which account is signed in.

The app does not read, modify, or store any other Google Cloud resource. It does not enumerate your projects, billing, or storage. The access is a network tunnel to a host you name.

Where credentials are stored

OAuth tokens are stored in the operating system keychain on your device (iOS Keychain or Android Keystore) and never in plain application storage. They are sent only to Google, to obtain tunnel access, and to no other party. They are not transmitted to any server operated by tn07.

What is not collected

• No analytics, telemetry, crash reporting, or advertising identifiers.
• No contact list, location, photos, or microphone access.
• No chat content, source code, or terminal output leaves your machines. Those live on hardware you control, and the app connects to it directly.

Revoking access

Sign out in the app to delete the stored tokens from your device. To revoke the grant entirely, visit myaccount.google.com/permissions and remove access. Either action takes effect immediately.

Third parties

Google Cloud is used for authentication and IAP tunnelling, subject to Google's own privacy policy. Source is published on GitHub. Nothing is shared with anyone else, and nothing is sold.
