However, you always have the right to delete your data by clearing app data or uninstalling the app.

12. International Users

Alculator is designed for use in the United States. State DUI laws and BAC limits are specific to US jurisdictions. If you use the app outside the United States, please be aware that laws in your jurisdiction may differ.
