Privacy Policy — Nonalys
Effective date: 2026-09-21 Last updated: 2026-09-21
Nonalys ("the app") is a Sudoku game, published by Balin Corp (Belo Horizonte, Brazil).
This policy explains what the app does with your data. The short version: nothing leaves your device.
What we collect
Nothing. The app has no user accounts, no sign-up, no analytics, no advertising, no crash reporting and no third-party SDKs that collect data. It makes no network requests, so there is no server that could receive your data in the first place.
Permissions
The app asks for no permissions. It does not use the microphone, the camera, your location, your contacts, your photos or your files, and it cannot read them.
Puzzles, progress and settings stored on your device
Puzzles are generated on your device. Your progress in them, your statistics and your preferences — theme, haptics, input and assistance settings — are saved locally on your device so the app remembers them between sessions. They stay on the device, are not readable by us, and are removed when you uninstall the app.
If you have device backup turned on (iCloud Backup or Google's Android backup), your operating system may include this app's data in your own backup, under your Apple or Google account. That backup is controlled by you and is never accessible to us.
Sharing, retention and deletion
We do not collect any data, so there is nothing to share, sell, retain or delete. No data is sold or shared with third parties, and no data is used for advertising or tracking. Uninstalling the app removes everything it has stored.
Purchases
Nonalys is a paid, one-time purchase sold through the Apple App Store and Google Play. Payment is handled entirely by Apple or Google under their own privacy policies. We receive no payment details and no personal information about you from your purchase.
Children
The app is not directed at children and does not knowingly collect data from anyone, of any age, because it does not collect data at all.
Your rights
Privacy laws such as the GDPR, the CCPA and Brazil's LGPD give you rights of access, correction and deletion over personal data held about you. We hold no personal data about you, so there is nothing to access, correct or delete. You are welcome to contact us to confirm this.
Changes to this policy
If this policy changes, the updated version will be posted at this same URL with a new "last updated" date. Material changes will also be noted in the app's release notes.
