Privacy
Glass Power Tools collects nothing about you. It has no account, no analytics, no advertising and no tracking, and no server of ours sits between you and your machines. This page lists what the app keeps and where, and everything it sends and to whom.
Last changed 18 October 2026. Every change to this page is recorded in the public repository's history.
What the app keeps, and where
- Your library (hosts, their services and their settings) is kept on your device and, with iCloud on, in your own private iCloud database. Only your Apple Account can read it. The developer cannot.
- Secrets (passwords, private keys, database credentials and the host keys you have trusted) are kept in the Keychain, and sync through iCloud Keychain. Keys made in the Secure Enclave never leave the device that made them.
- Favorites, workgroups, projects and terminal settings sync through iCloud's key-value storage. So do each device's name, how many connections it made per day to each machine, and how many minutes it was in use on each, with no times of day, for the library's overview of the last 30 days.
- On the device only: query history (with literal values removed unless you turn that off), SQL drafts, session recordings you choose to make, and the app's diagnostic logs. Files you download stay where you put them.
What leaves your device
- The connections you make. Terminal, database and remote-desktop traffic goes between your device and the machines you add, directly or through the SSH machines you choose to route it through.
- iCloud. The library and settings above sync through your iCloud account, under Apple's privacy policy.
- Tailscale, if you connect it. If you connect a Tailscale account to find your devices, the app asks Tailscale's API for your tailnet's devices, with the credentials you give it, which are kept in the Keychain.
- Links you open. A link a terminal prints opens only after you confirm it. A link to a 3D model is then downloaded from that address, and kept only if it is a model.
- Nothing from the on-device assistant. The database assistant runs on your device through Apple Intelligence. What it is given is not sent to a server.
- Update checks on the Mac. The Mac app checks glasspowertools.com for updates and downloads them from GitHub. On its second launch it asks whether to check automatically. These are ordinary web requests that carry nothing about you. On iPhone, iPad and Vision Pro, updates come from the App Store.
- Crash reports, if you share them. If you choose in your device's settings to share analytics with app developers, Apple may pass crash reports for this app to the developer. That choice and those reports are Apple's.
Permissions the app asks for
- Local Network (iPhone, iPad and Vision Pro), to reach machines on your network.
- Face ID, Optic ID or Touch ID, only to use an SSH key kept in the Secure Enclave.
