Privacy — Casellina
Last updated 17 October 2026
The principle
Casellina brings nine logic puzzles together in one app for iPhone and iPad. It asks for no permissions at all — not one — and it has no account and no server of ours. It arrives as the 2.0 update of Pareggio, whose games it keeps. 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
Casellina records what you put into it:
- the games you have played, in each of the nine puzzles: the grid, what you placed and your moves, so you can undo them, the size and level, how long it took and how many hints you used, when you started and when you finished
- which daily challenges you have played
- your settings, how many free games you have started today, and whether you bought Pro — these three stay on the device and never sync
- two numbers per game for the friends’ ranking of Cerchia, if you use it — games finished and daily challenges solved — and a short summary of today’s challenges, both written on the device, in a folder only Nidello apps and their widgets can read
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. Casellina 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 sync through your own private iCloud, in the container that Pareggio already used, in your Apple Account. We have no way to open it. Turn iCloud off for the app and everything stays on the device.
- Your Stelletta games, on the same device
- If the Stelletta app is installed, Casellina reads a copy of its games, on the device, from the folder the two apps share, and adds them to its own. Nothing is sent anywhere, and Stelletta’s own data is left untouched.
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 App Store. If you buy Casellina 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. From the About screen the app can also offer another Nidello app; tapping through opens an App Store card, and the counters that decide when to offer it stay on your device. When you share a daily challenge result or export your games, the file or short text goes only where you send it.
Your data is yours
Your games are on your device and in your own iCloud, where you can delete them whenever you want, without asking us. Three of the games can also export all their games to a file, from their settings. Delete the app and what was only on the device is gone; what synced to iCloud goes when you remove the app 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.
