The goal of the noSpy project is to provide you with an app that does not explore any data or store it for further use on the internet. In order to use services of your mobile phone, it is sometimes necessary to claim certain permissions. NoSpy apps only use the permission required for each feature and no more. So you can be sure that your personal privacy is always the top priority.

No permissions, no ads and all for free. What more do you want. If you have questions or improvements write us an email. If you like the app, we would appreciate a review.
