Stulch is a thatching sandbox that runs entirely on your device. This page explains, plainly, what the app does and does not collect.
Stulch does not create an account for you, does not use analytics or advertising, and makes no network calls while you play. Everything you do in the app — laying courses, cutting a ridge, filling the scrapbook — stays on your device. Nothing is sent anywhere unless you deliberately use the Share button.
So the app can remember your lane and your scrapbook between visits, it keeps the following locally, in the app's own Application Support folder and in standard preference storage. None of it is transmitted to us or to anyone else.
| What | Where | Why |
|---|---|---|
| Lane and cottage progress | JSON file, Application Support | So each cottage stays thatched between sessions |
| Scrapbook cards and ledger counts | JSON file, Application Support | So your collection of finished and spotted roofs is kept |
| Photos you choose to pin | JPEG file, Application Support | So a spotted-thatch photo stays with its scrapbook card |
| Settings (sound, haptics, day length, morning bell) | UserDefaults | So your preferences persist |
Stulch asks for the camera only when you tap "Take a photo" inside Spot a thatch, to photograph a real thatched roof you have come across and add it to your scrapbook. It asks for your photo library only when you tap "Choose a photo" in the same screen, using Apple's picker. A photo you take or choose is saved only inside the app's own storage on your device. It never leaves your device unless you use the Share button yourself to send a card elsewhere.
Stulch can offer an optional local "morning bell" reminder. Permission is requested only at the moment you switch this on in Settings, never before, and the reminder is scheduled entirely on your device.
Stulch contains no user-generated content shared with others, no chat, and no purchases, and is suitable for a general audience. We do not knowingly collect personal information from anyone, including children.
If Stulch's data practices ever change, this page will be updated and the date above will change accordingly.
Questions about this policy can be sent through the support page.
