Does LumiCalc collect my personal data?

No. LumiCalc does not collect any personal information. All settings and theme data are stored locally on your device only. We use App Group to share data between the app and keyboard extension, but this data never leaves your device.

Why do I need to enable "Allow Full Access" for the keyboard?

Full Access is required for the custom keyboard to function properly. This allows the keyboard to access necessary system functions. We do not collect or transmit any data - all information stays on your device.
