As part of our commitment to protecting your privacy, we collect information in a way that does not directly identify you.

Also, all data can be deleted from the Application settings menu at any time.Under the General Data Protection Regulation (GDPR)We recognize the rights of individuals under the GDPR, including the right to erasure (“the right to be forgotten”).

Should you choose to stop using our Application, any data previously collected and anonymized cannot be individually assessed or deleted, except by the user themselves through the Application, as it does not constitute personally identifiable information under the GDPR.Under the California Consumer Privacy Act (CCPA)Similarly, the CCPA provides California residents with specific rights regarding their personal information. This includes the right to request the deletion of personal information. However, because our Application only processes anonymized data that cannot be linked back to any individual, these rights do not apply to the information processed by our Application. The anonymized data is beyond the scope of information that can be requested for deletion under the CCPA, as it cannot be associated with any consumer or household. However the user themselves can delete all data from within the Application settings menu.Our CommitmentPlease be assured that our use of anonymized data is aimed at improving user experience and enhancing our Application without compromising individual privacy.
