By downloading and using CallOne ("the App"), you agree to be bound by these Terms of Service. If you do not agree, please do not use the App.
CallOne is a simple habit-tracking and reminder utility designed to help users remember to call personal contacts on a weekly basis. The App is provided "as is" and intended strictly for behavioral tracking (reminders and streaks).
CallOne is a productivity tool. We make no medical, emotional, or therapeutic claims. The App is entirely behavioral and neutral. It is not designed to treat loneliness, depression, or provide emotional therapy.
Since the App operates locally on your device, you are solely responsible for managing its content and maintaining your device's security. If you uninstall the App or lose your device, your streak data will be lost, as we do not offer cloud synchronization.
To the absolute maximum extent permitted by law, CallOne and its developers shall not be liable for any direct, indirect, incidental, or consequential damages resulting from the use or inability to use the App, missed calls, or lost data.
