1. Introduction ​

Rule of Three is an educational app that helps users learn and calculate proportions using the Rule of Three method.
We care about your privacy. This policy explains what data the app collects, how it is used, and your rights.

2. Information We Collect ​

Rule of Three is designed to operate without collecting any personal data from users.

2.1 Data NOT collected ​

  • Contacts
  • Photos or media from your device
  • Location data
  • App usage analytics
  • Device identifiers
  • Advertising IDs

2.2 Optional Share Feature ​

If you choose to use the share card feature, the app generates a temporary image based on the calculation result.

  • This image remains only on your device.
  • It is only shared if you choose to send it through another app (WhatsApp, Facebook, Messages, Email, etc.).
  • We do not access, collect, store, or transmit these images.

  • Analytics platforms
  • Advertising networks
  • Tracking services
  • External servers

All functionality happens locally on your device.

6. Data Security ​

Because no data is collected or stored, there is no risk of personal data exposure.
All calculations and generated images occur locally on the user’s device.

7. Your Control and Choices ​

You remain in full control of:

  • Whether to use the optional share feature
  • Where any generated image is shared

The app does not store or retain any data.
