The App requires no account and does not request your name, phone, e-mail or other contact details.

4. Data stored on your device

The information you create (tasks, notes, tags, timer settings, statistics, history) is stored locally on your device and is not transmitted to the Operator. It is deleted when you uninstall the App or clear its data.
