Frequently asked questions
How do I report a bug or request a feature?
Send us an email at guoyingtao@outlook.com describing what happened or what you'd like to see. Screenshots and your device model help a lot.
Is my data collected?
No. Our apps don't collect personal information, don't track you, and keep your data on your device. See our Privacy Policy for details.
How do I get an app back after reinstalling or on a new device?
Everything you've paid for is tied to your Apple Account. For a paid app, just re-download it from the App Store — you won't be charged again. For apps with in-app purchases, open the app and use its "Restore Purchases" option. Either way there's no extra cost.
Do the apps work offline?
Most of our apps run entirely on your device and don't require an internet connection. Check the individual app for any features that need to be online.
How do I request my data be deleted?
Because we don't collect your data, there's nothing on our servers to delete. To remove data stored on your device, simply delete the app.
