Anonymized usage data may be stored securely on Firebase servers. This data is aggregated and cannot be used to identify individual users.
We implement appropriate technical and organizational measures to protect your information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.
We may share information with trusted third-party service providers who assist us in operating the App, conducting our business, or servicing you, provided those parties agree to keep this information confidential.
We may disclose your information if required to do so by law or in response to valid requests by public authorities, such as a court or government agency.
In the event of a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you of any such change.
We do not sell, rent, or trade your personal information to third parties for marketing purposes.
