Effective date: July 13, 2026
Artisan of Glass ("the app") is made by Curly Doggo Limited. This policy explains what data the app handles and why. The short version: there is no account, there are no third-party ads, we never sell data, and the little we do collect is pseudonymous.
Your puzzle progress, solved-window history, best times, hint counters, and settings are stored only on your device (and in your device backups, which Apple manages). We cannot see them.
When you tap "Save to Photos", the finished window image is written to your photo library after you grant permission. The app never reads your photo library — it only adds images you explicitly save.
The daily reminder, if you turn it on, is a local notification scheduled on your device. It involves no server and sends nothing anywhere.
We use PostHog, hosted in the European Union, to understand how the app is used — which puzzles get played, where players get stuck, whether the tutorial works. This data is tied to a randomly generated identifier, not to your name, email, or Apple ID, and includes:
We do not use analytics data to track you across other companies' apps or websites, and we do not sell it.
Payments are processed entirely by Apple. We never receive your name, card number, or billing address.
To unlock premium features after a purchase (including on a new device, via Restore Purchases), we use RevenueCat, a subscription-management service. RevenueCat receives the Apple purchase receipt, your purchase history for this app, and the same kind of random pseudonymous identifier used for analytics. RevenueCat processes this data on our behalf and does not sell it.
You can manage or cancel a subscription anytime in Settings → Apple Account → Subscriptions on your device.
The app currently shows no third-party ads. If a future version adds them, this policy will be updated first and the app will ask for any consent the law and Apple require before any ad data is collected.
Data goes only to the processors named above (PostHog, EU; RevenueCat, US — under standard data-protection agreements) and to no one else. We do not sell or rent data, and we do not combine it with data from other sources.
