NumberFlow Privacy Policy

Last updated: July 2026

NumberFlow (“the app”) is developed by Neobile LLC. This policy explains what happens to your data when you use NumberFlow.

The short version

NumberFlow does not collect your data. There is no account, no analytics, no advertising, and no tracking. Your progress, coins, streaks, and stats stay on your device. The game plays fully offline; the only optional online features are Apple’s own Game Center and App Store purchases, described below.

What NumberFlow stores, and where

Your progress, daily records, and stats are stored in a local database on your device, using Apple’s SwiftData framework.
Your coin balance and streak-savers are saved in a local file and mirrored to your device’s Keychain, so reinstalling the app does not erase items you have purchased.
The puzzles are generated on your device from a date seed. No board data is downloaded or uploaded.

Purchases

Any in-app purchases are handled entirely by Apple through the App Store. The developer never receives your payment details; the app only learns whether a purchase completed, validated on-device.

Notifications (optional)

If you turn on the daily reminder, NumberFlow schedules a local notification on your device. There is no push server and no message is sent over the network.

What NumberFlow does NOT do

No account or sign-up of any kind.
No analytics, crash reporting, or advertising SDKs.
No ads in this version, and therefore no App Tracking Transparency prompt.
No tracking across apps or websites.
No data is sold, rented, or shared with third parties.

Children’s privacy

NumberFlow is not directed at children and does not knowingly collect data from anyone, including children, because it does not collect data at all.

Changes to this policy

If this policy changes, the updated version will be posted at this same URL with a new “Last updated” date.
