NumZen – Privacy Policy

Last updated: July 15, 2026

Your data stays on your device

NumZen is designed to be private. Your puzzle progress, streaks, statistics, and preferences are stored locally on your device. We do not operate any servers, and we never collect, transmit, or have access to your data. NumZen does not require an account.

Daily challenges work offline

The daily challenge is generated on your device from the date itself, so everyone in the world gets the same puzzles without any network connection. NumZen never sends anything to the internet.

No ads, no tracking

This version of NumZen contains no third-party advertising, no analytics SDKs, and no tracking of any kind. If a future version introduces ads, this policy will be updated before release and any tracking will require your explicit consent through Apple's App Tracking Transparency prompt.

In-app purchases

NumZen Unlimited is a one-time purchase processed entirely by Apple. We do not receive or store any payment information.

Children's privacy

NumZen does not collect personal information from anyone, including children. There are no accounts, no social features, and no data leaves the device.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated date.
