No Cloud Sync: We do not upload your data to any servers.
No Account Required: You can use VocaFlip without creating an account.
Technical Data
We may collect anonymous, aggregated analytics data through Apple's App Analytics to improve app performance. This data does not identify individual users.
Third-Party Services

Children's Privacy
VocaFlip is suitable for users of all ages. We do not knowingly collect information from children under 13.

⚙️ Your Privacy Choices
VocaFlip does not collect, store, or share any personal data.
What This Means For You

Your Data Rights
Access: All your data is stored on your device. You can view it anytime within the app.
Export: Use the Export feature to download your vocabulary sets.
Delete: Delete any study set, folder, or individual item within the app. Uninstalling the app removes all data.

No Tracking
VocaFlip does not use:
Analytics tracking
Advertising identifiers
Third-party SDKs that collect data
Cookies or web beacons
Apple App Analytics
Apple may collect anonymous, aggregated app usage statistics through App Analytics if you have opted in on your device. This is controlled by your device settings, not by VocaFlip. To manage this:
