This privacy policy applies to the Cost Per Use app (hereby referred to as "Application") for mobile devices that was created by Yapeng Li (hereby referred to as "Service Provider") as a Free service. This service is intended for use "AS IS".
The Application does not obtain any information when you download and use it. Registration is not required to use the Application.
We do not collect, store, or share any of your personal information.
This Application does not collect precise information about the location of your mobile device.
Since the Application does not collect any information, no data is shared with third parties.
All data created by you (items, prices, usage logs) is stored locally on your device. If you enable iCloud Sync (Pro feature), your data is securely stored in your private iCloud container to sync across your devices. This data is managed by Apple and we do not have access to it.
The Application is not used to knowingly solicit data from or market to children under the age of 13.
The Service Provider does not knowingly collect personally identifiable information from children. If you have reason to believe that a child has provided personally identifiable information to the Service Provider through the Application, please contact the Service Provider so that they will be able to take the necessary actions.
This Privacy Policy may be updated from time to time for any reason. The Service Provider will notify you of any changes to their Privacy Policy by updating this page with the new Privacy Policy. You are advised to consult this Privacy Policy regularly for any changes, as continued use is deemed approval of all changes.
If you have any questions regarding privacy while using the Application, or have questions about the practices, please contact the Service Provider via email at: costpreuse@gmail.com
