Terms of Use

Last Updated: March 5, 2026

These Terms of Use (hereinafter referred to as "Terms") constitute a legally binding agreement between you (hereinafter referred to as "User" or "You") and the service provider (hereinafter referred to as "We" or "Us") regarding the use of the Authenticator Pro mobile application (hereinafter referred to as "the App" or "the Service").

IMPORTANT NOTICE: By downloading, installing, using, or subscribing to this App, you acknowledge that you have read, understood, and agreed to be bound by these Terms. Please read the sections regarding [Subscription Fees], [Nature of Digital Goods], [Disclaimer of Warranties], and [Class Action Waiver] carefully. If you do not agree to any part of these Terms, please discontinue using the App immediately.

1. Nature of Service and Subscription

The App provides Two-Factor Authentication (2FA) code generation and related data management services. The App operates under a "Free Download + Paid Subscription" model.

Subscription Services: Certain core features of the App (e.g., Cloud Backup, Multi-device Synchronization, Unlimited Accounts) are Premium services that require an active paid subscription.
Payment and Authorization: Upon confirmation of purchase, payment will be charged to your Apple ID (iTunes) account. You confirm that the subscription action via your Apple ID is an expression of your true intent.
Nature of Digital Goods:
- Immediate Delivery: The subscription service provided by this App is classified as digital content and online service. Once you initiate the subscription and the service is activated (payment completed), the service is deemed to have been delivered.
- Availability equals Service: The subscription payment covers the availability of Premium features and server resources. Regardless of whether you actually open or use the App, subscription fees apply. No refunds will be granted for "non-use," "forgetting to cancel," or "lack of knowledge."
Auto-Renewal: The subscription automatically renews unless auto-renew is turned off in your Account Settings at least 24 hours before the end of the current period.
Subscription Management: You can manage or cancel your subscriptions at any time after purchase in your Apple ID Account Settings. Deleting the App does not automatically cancel the subscription.
Free Trial: If a free trial period is offered, it will automatically convert to a paid subscription at the end of the period. This is a standard mechanism of the Apple App Store. Please monitor your subscription status before the trial ends.

2. User Responsibilities and Account Security

Data Security: You are solely responsible for maintaining the security of your device and access to the App. We strongly recommend enabling the App Lock (Passcode or FaceID) feature to prevent unauthorized access.
Backup Responsibility: You acknowledge and agree that it is your responsibility to perform regular backups of your authentication data. Although the App offers an iCloud Cloud Backup feature, we are not liable for data loss caused by iCloud service failures, network issues, user errors, or failure to retain recovery codes. It is strongly recommended to ensure data has been successfully backed up or exported before deleting the App or changing devices.
Prohibited Activities: You agree not to "jailbreak" or "root" your phone, as this may compromise the App's security and lead to data leaks. Attempting to extract source code, reverse engineer, or create derivative versions of the App is strictly prohibited.

3. Intellectual Property

The App and all its content (including but not limited to source code, databases, software, designs, audio, video, text, photographs, and graphics), as well as the trademarks, service marks, and logos contained therein, are owned by or licensed to the service provider and are protected by copyright and trademark laws.

5. Updates and Modification of Service

You agree that performing regular self-backups (e.g., iCloud backup or export to file) is your sole responsibility. We assume no liability to you or any third party for data loss or inability to access resulting from service termination, App removal, or feature changes.

6. Third-Party Links and Costs
