Support

Need help with purchases, backups, export, or project data? Start here.

Restore Purchases
Use the standard App Store restore flow. If Pro does not appear after restore, make sure you are signed into the same Apple ID that made the purchase.
Backups and restore
Backups are user-owned `.glassbook` package files. Keep a copy in Files, iCloud Drive, or another location you control.
Photos and PDFs
Imported project photos stay on the device unless you export them. PDFs and CSVs are generated on device and remain under your control.
Languages
GlassBook follows the system language and supports English and Simplified Chinese.
Privacy

GlassBook is designed to work without an account and without a server-side profile.

On-device by design
Project data, settings, photos, and milestones are stored locally on your device using the app's on-device data model.
No ad tracking
GlassBook does not use an advertising profile or cross-app tracking system.
Apple handles purchases
In-app purchases are processed by Apple through StoreKit and App Store infrastructure.
Backups are user controlled
Exported backup files, PDFs, and CSVs stay wherever you choose to save them.
Need more help?

If you still need assistance, check the App Store listing and include your device model, iOS version, and a screenshot so the issue can be reproduced quickly.

For review
