Short version: Glasshouse collects nothing. It has no server, no account, and no network. Everything it reads stays on your device. The developer has no access to any of your data.
Glasshouse is an on-device privacy education tool. With your permission, it reads signals that already live on your iPhone — such as Photos metadata, Calendar, Contacts, Health, Location, and Motion — and analyzes them locally, using an AI model that runs on your phone's own chip (Apple Intelligence). The result is shown only to you, on your device.
Nothing. Glasshouse contains no networking code. It does not transmit, upload, sell, share, or store your data anywhere outside your device. There is no server to receive it, no analytics, no advertising, no tracking, and no user account. You can verify this yourself: turn on Airplane Mode and the entire app still works.
Glasshouse asks for access to sensitive data (Photos, Calendar, Contacts, Health, Location, Motion, and your advertising identifier) only to demonstrate, on your device, what that data can reveal. iOS requires you to explicitly allow each one, and you can grant only what you choose — the app simply explains less if you share less. You can revoke any permission at any time in Settings ▸ Privacy & Security.
Glasshouse also checks (read-only) whether certain apps are installed, to show you that any app can do this without permission. This check is displayed only to you and is never recorded or transmitted.
None. The only time any data leaves your phone is if you choose to export a report as a PDF and share it yourself via the iOS share sheet. That action, and where it goes, is entirely your choice.
Glasshouse is not directed at children and collects no data from anyone.
If this policy ever changes, the updated date above will change. Because the app collects nothing, any change would only ever clarify, not expand, data use.
Questions about privacy in Glasshouse can be sent to the developer via the support link on the App Store listing.
