Privacy Policy

Sudoku Kids: Learn & Play · Last updated November 6, 2026

The short version: Sudoku Kids does not collect, store or share any personal information. There are no accounts, no ads, no analytics, no tracking and no in-app purchases.

What the app stores

To remember progress, the app saves the following only on your device:

Player names and avatars you choose (for example "Maya 🦊")
Stars, trophies, puzzles solved, best times and lesson progress
The puzzle currently being played
Settings such as sounds, vibration and the break reminder

This information never leaves the device. We cannot see it, and it is deleted when the app is removed. A grown-up can also reset or remove a player in the app's Grown-ups area.

What the app does not do

It does not collect names, email addresses, locations, photos, contacts or device identifiers.
It does not use the internet. Puzzles are created on the device.
It contains no advertising, analytics or third-party software development kits.
It does not link to websites or social media from areas children use.

Children's privacy

Sudoku Kids is designed for children. Because no personal information is collected, the app is designed to meet the Children's Online Privacy Protection Act (COPPA) and similar laws such as the GDPR. Settings meant for adults sit behind a parental gate.

Read-aloud hints

When "Read hints out loud" is on, the app uses Apple's built-in speech voice on the device. No audio is recorded and nothing is sent anywhere.

Changes

If this policy ever changes, the new version will be posted on this page with a new date.
