Privacy Policy
Your study data (progress, scores, bookmarks) stays entirely on your device. We don't have accounts or servers that store your personal information.
Advertising & Analytics
We use Meta (Facebook) SDK to measure the effectiveness of our advertising campaigns. When you allow tracking through Apple's App Tracking Transparency prompt, the following may be collected:
- IDFA (Identifier for Advertisers) — used to attribute app installs to ad campaigns
- Basic app events — such as app installs and purchases, shared with Meta for ad measurement
You can opt out of tracking at any time by declining the App Tracking Transparency prompt or by going to Settings > Privacy & Security > Tracking on your device.
Purchases
Purchases are handled entirely by Apple's App Store. We do not receive or store your payment information. See Apple's Privacy Policy for details.
No Data Selling
We do not sell your personal data. We do not serve ads within the app. The only third-party data sharing is with Meta for ad attribution as described above.
