FAQ

How do I add or rename a habit?

Tap + to add. To rename, enter Edit Mode (pencil icon), select the habit, change the name, and save.

How does the progress grid work?

The grid shows the last 12 months. Each cell reflects how many habits you completed that day:

Level 0: Gray (0% complete)
Level 1: Very light green (1-20%)
Level 2: Light green (21-40%)
Level 3: Medium green (41-60%)
Level 4: Dark green (61-80%)
Level 5: Darkest green (81-100%)

Can I back up or migrate my data?

Data is stored in UserDefaults. iCloud device backups may include this data. If you reinstall on the same device and restore from iCloud backup, your data can return. The app does not currently export/import data.

Does the app track or share my data?

No. The app keeps data on your device and does not transmit it. See the Privacy Policy for details.

How do I report a bug or request a feature?

Email greenluck3.14159@gmail.com with steps to reproduce, your iOS version, and screenshots if possible.

Troubleshooting

Progress not saving? Ensure you’re not in Low Data Mode/Storage critically low; then force-quit and reopen the app.
Widgets not updating? Open the app once to refresh data; verify Background App Refresh is enabled.
After reinstall, data missing? Restoring from an iCloud device backup may recover UserDefaults data. If not, there is no server backup.
App crashes on launch? Reboot the device. If it persists, contact support with crash details and your iOS version.
