Privacy Policy

Effective date: July 17, 2026

Stained Glass Calculator runs its project calculations locally and does not require an account.

Information We Collect

The app does not ask for your name, email address, location, contacts, photos, or login credentials. Project inputs and material presets are stored on your device.

Purchases

In-app purchases are handled by Apple. RevenueCat may process purchase identifiers, entitlement status, app identifiers, platform metadata, and an anonymous customer identifier needed to unlock Pro and restore purchases.

Exports

When you export a CSV estimate, the file is created on device and passed to the iOS share sheet. You choose the destination. We do not upload the file to a Mindsle server.

Remote Configuration

The app may request non-personal configuration such as legal links, feature availability, or warning text. Core calculations continue to work from bundled defaults if that request is unavailable.
