Summary

Number Sense is designed to be privacy-friendly. The App stores your game progress locally on your device. The App uses TelemetryDeck for anonymous, cookie-less analytics to understand general usage (for example, which screens are used and whether the app is stable).

  • No accounts. You do not need to sign in.
  • No user profiling. We do not try to identify you.
  • No selling of data. We do not sell your data.

Information the App processes

1) Local data on your device

The App stores gameplay-related information locally on your device (for example, progress and preferences). This data is used to provide the game experience and is not uploaded by default.

2) Analytics (TelemetryDeck)

The App uses TelemetryDeck to collect privacy-friendly analytics. This helps improve the App by understanding aggregated usage patterns and detecting issues.

  • Example events: app launches, screen views, button taps, level progression (in aggregate).
  • Technical context: device and OS information in a form typically used for diagnostics (for example, iOS version).
About identifiers: TelemetryDeck may use a pseudonymous, app-generated identifier to count unique devices or sessions. It is designed to avoid tracking individuals and does not provide us with a way to directly identify you.

How we use information

  • To operate the App (local progress and preferences).
  • To understand general usage and improve the App (TelemetryDeck analytics).
  • To diagnose crashes or unexpected behavior based on aggregated signals.

Sharing

We do not sell your data. We share limited analytics information with our analytics provider: TelemetryDeck, solely for the purpose of operating and improving the App.

Data retention

Local data remains on your device unless you delete the App. Analytics data is retained according to TelemetryDeck’s retention settings and policies.

Children’s privacy

The App is intended for a general audience and is not specifically directed to children. We do not knowingly collect personally identifiable information from children. If you believe a child has provided personal information, contact us and we will address it.

Your choices

  • You can delete the App to remove locally stored data from your device.
  • If the App provides an in-app analytics toggle in the future, you will be able to opt out there.
