Privacy Policy
Chinese Antiquities Jigsaw · Last updated 8 October 2026
Chinese Antiquities Jigsaw does not collect, store, or transmit any personal data.
What we collect
Nothing. Specifically:
- No account. There is no sign-in, no login, and no user profile.
- No analytics. No analytics SDK is included. We do not know how you use the app.
- No advertising. No ad SDK is included. There are no ads.
- No tracking. The app does not track you across apps or websites.
- No server. The app does not talk to any server of ours. Apart from Apple's own purchase check, it never uses the network at all.
What stays on your device
Two kinds of data are written to your device's local storage, and they never leave it:
| Data | Purpose |
|---|---|
| Puzzle progress | Which artifacts you have completed, your best times, and any puzzle you left half-finished, so you can continue later |
| Preferences | Your language choice and whether sound is on |
Uninstalling the app deletes all of it. We have no copy and no way to obtain one.
Purchases
The one-time “Unlock Everything” purchase is processed entirely by Apple through the App Store. We never see or receive your name, payment card, or billing address. Apple provides the app only with a yes/no answer to “has this Apple ID purchased the unlock”, which is why the app can restore your purchase on a new device.
Apple's own handling of that transaction is governed by Apple's Privacy Policy.
The artwork and the facts
Every illustration in the app is an original hand-drawn work made from a real museum object. They are not photographs of museum objects, and no museum image is reproduced. Each artifact card states exactly which object the drawing was made from, so the claim can be checked.
Periods, materials, dimensions, holding institutions and excavation sites come from published museum and archaeological sources.
Children
The app is suitable for all ages and collects no data from anyone, including children under 13.
Changes
If this policy ever changes, the date at the top will change with it. Because the app collects nothing, we do not expect it to.
