Privacy

Privacy policy

Short version: no accounts, no ads, no selling data, analytics only with your consent. Your designs stay on your device.

This website

Analytics. We use Google Analytics 4 to count page views and a few events (for example, which tool was used). It loads only after you choose “Allow analytics”, and never if your browser sends Global Privacy Control. Advertising features are off.
Local storage. Your analytics choice and your ticks on the safety checklist are kept in your browser’s local storage. They never leave your device.
The cost calculator runs entirely in your browser; the sizes and prices you type are not sent anywhere.
No accounts or forms. Email links open your own mail app.
Hosting logs. Our host (Google Firebase App Hosting) keeps standard request logs for security and reliability.

Saved in your browser. Designs are stored in your browser on your device. There is no account and designs are not uploaded.
Analytics follows the same consent rules as this website and never includes your design, its name, its location or the contents of a link.
Share links carry the design inside the link itself; nothing is stored on a server.
Back up by exporting. Clearing site data for app.opencatio3d.com removes local projects.

No account. Projects, photos and scans are stored on your device.
Permissions when you need them. Camera, photo library and location access are requested only when you use a feature that needs them, with an explanation.
Raw scans stay private unless you export them, and can be deleted in the app.
The App Store privacy details will be published with the app and this section updated to match.
