Hi there! It sounds like you accidentally removed the Happy Color app icon and when you re-downloaded it, you lost all your colored photos. Let me clarify a bit—is the app installed again now and you can open it, but none of your previous progress or colored pictures show up?

If that’s the case, it’s usually because the app’s local data was deleted during the uninstall, and your progress needs to be synced back from the cloud. Happy Color saves your completed pictures and progress only if you’ve logged in using an account like Facebook, Google, or Apple ID before uninstalling.

Here’s what to do step-by-step on your Mac using OS X 10.15.7:

1. Open the Happy Color app again.
2. Go to the app’s Settings menu.
3. Under General, look for Log in to sync data (or similar wording).
4. Sign in carefully using the same Facebook, Google, or Apple ID account you used previously.
5. Allow some time for the app to sync your data. You’ll see a cloud icon that disappears once syncing is complete.

Important note: Only the pictures you fully completed and synced before uninstalling can be recovered this way. If you had not logged in previously or your progress was only saved locally, unfortunately those will be lost1.

Could you let me know if you had logged in with any account before? Also, are you seeing the login option inside the app’s settings? This info will help me guide you further.
