Privacy Policy

Last updated: 6 October 2026

The short version

Qwartz does not collect any data. It has no account, no analytics, no telemetry and no third-party tracking. Your models stay where you save them.

What Qwartz does on your device

• Saves .qwartz files to wherever you tell it (Files app, iCloud, local disk).
• Imports models from FBX or OBJ files you open.
• Exports to glTF, OBJ, STL, GIF, or MP4 to wherever you tell it.
• Stores app preferences (lighting, grid, snap, extrude depth) in standard iOS / macOS preferences.

Network access

Qwartz contacts Apple's servers only to verify your purchase via StoreKit. That request is between your device and Apple; Qwartz does not see who you are. The app itself makes no other network requests.

Crash reports

If you've enabled "Share with App Developers" in your system settings, Apple may forward anonymized crash reports. We use these only to fix bugs. We can't identify you from them.

Your files

.qwartz documents are standard ZIP archives stored wherever you save them. They stay on your device, or in the iCloud Drive or other storage you choose, and leave it only when you share them yourself. We have no access to them.

Children

Qwartz is suitable for users of all ages. It collects no personal data, so the same protections apply to everyone.
