This Privacy Policy aims to explain to you the relevant rules and practices of our company (hereinafter referred to as "we") regarding the collection, use, storage, sharing and protection of your personal information when we help you establish a secure environment to manage and protect your two-factor authentication (2FA) codes while fully protecting your privacy through the iOS software Authenticator App-MFA&2FAAuth (hereinafter referred to as "this Software") developed by us. Please carefully read and understand the content of this Privacy Policy before using this Software. If you do not agree to any条款 of this Privacy Policy, please do not use this Software.

We need the following mobile phone permissions:

The above information is processed locally and we will not upload it to the server.
The data you add during the use of the Software, including but not limited to account information, keys, passwords, etc., is locally encrypted by the application on your device. Only you can access your data, and we cannot read or decrypt it.
We use Firebase services provided by Google:
• Firebase Crashlytics: Collect anonymous crash logs to help locate and fix problems

Your encrypted data will be securely stored on your device, and you can delete the application at any time and clear the data generated during your use of the Software.
Before deleting the application, if necessary, please be sure to back up or transfer your two-factor authentication accounts, because deleting the application may prevent you from accessing the stored verification codes.
