Privacy — Incastro
Last updated 14 October 2026
The principle
Incastro is a logic game for iPhone and iPad. It asks for no permissions at all — not one — and it has no account and no server of ours. Its daily challenges ship inside the app, so it never downloads them. We never receive, store or see any of your data. There is nothing for us to sell, lose or hand over, because there is nothing on our side to begin with.
What the app keeps
Incastro records what you put into it:
- the games you have played: the grid, the numbers you placed, the level, the daily challenge it belongs to if any, how long it took and how many hints you used
- your settings: mistakes flagged or not, haptics, the timer and the colour theme
Where it lives
On your device. If you turn iCloud on, it also syncs through your own private iCloud database, which Apple encrypts and which we cannot open, read or list. We have no key and no access of any kind.
What it asks permission for
Every one of these is optional. Refuse any of them and the rest of the app keeps working.
- None of the usual ones
- No camera, no microphone, no location, no contacts, no photos, no notifications. Incastro declares no usage description because it needs none — iOS will never show you a permission prompt for it.
- iCloud, if you leave it on
- Your games and settings sync through your own private iCloud, in a container that belongs to Incastro alone, in your Apple Account. We have no way to open it. Turn iCloud off for the app and everything stays on the device.
What leaves the device
Nothing. The app makes no network request of its own: no analytics, no crash reporting, no advertising, no third-party kit of any kind. It works in airplane mode.
The one exception is the purchase itself: if you buy Pro, your device talks to the App Store, as it does for any purchase, and the purchase is checked on the device. That exchange is between you and Apple. We are told a sale happened; we are never told who you are. The App Store also opens if you tap the occasional suggestion of another Nidello app, which you can turn off in the settings. When you share a daily challenge result, the short text — the shape of your grid, without the numbers — goes only where you send it.
Other Nidello apps
If you also use Cerchia, Incastro leaves it two numbers on your device, through the storage Nidello apps share there: how many games you have played and how many daily challenges you have solved. Nothing else about your games. Cerchia shows them only in the circles where you choose to show your statistics, for the ranking among friends. None of it leaves the device this way.
Your data is yours
Export your games as a JSON file from the settings, whenever you want, without asking us. Delete the app and what was only on the device is gone; what synced to iCloud goes when you remove Incastro from your iCloud settings. We cannot recover any of it for you, because we never had it.
Children
The app is not directed at children and collects nothing about anyone, of any age.
Changes to this page
If the app ever starts doing something this page does not describe, this page changes first. The date at the top says when it last did.
Your rights
Quebec’s Law 25 and similar laws elsewhere give you the right to access, correct and delete the personal information a business holds about you. In our case the answer is the same every time: we hold none. Your information is on your device and in your own iCloud, where you can already read, change and delete all of it yourself.
