GlassBook Privacy Policy

GlassBook is designed as an on-device app. This policy explains how the app handles project data, backups, and purchases.

Support Home
What we collect
Project content
Project names, dimensions, materials, labor entries, photos, and notes are stored locally on your device so GlassBook can work offline.
App settings
Preferences such as unit system, currency, pricing defaults, and Pro status are stored locally on device.
Backup files
Backup export files are created at your request and remain under your control.
Purchases
In-app purchases are handled by Apple through StoreKit and App Store services.
What we do not do
No account required
You do not need to create an account or sign in to use GlassBook.
No ad tracking
GlassBook does not use advertising identifiers or cross-app tracking.
No server profile
GlassBook does not maintain a server-side user profile for project data.
No unnecessary sharing
The app does not share your project data with third parties beyond Apple's required purchase infrastructure.
Photos and files

If you import photos into a project or export a PDF, CSV, or backup package, those files stay wherever you choose to save them. GlassBook does not upload them to a GlassBook-owned server.

Changes

We may update this policy when the app changes. The latest version will always live at this URL.
