1. Acceptance

By downloading, installing, or using R-Guard (the “App”), you agree to these Terms of Service. If you do not agree, do not use the App.

These terms are published by Rosario Group LLC. The official web version at rosariogroupllc.com prevails when an updated version is published.

2. Service description

R-Guard is a two-factor authentication (2FA) application that generates TOTP/HOTP codes locally on your device, may store secrets in the system Keychain, offer biometric or hardware-key lock (e.g. YubiKey via NFC), a codes widget, encrypted export, and optionally push-based login approval for Rosario Group SSO when the device is paired.

The App does not replace your organization’s security judgment and does not guarantee that third-party accounts cannot be accessed without authorization.

3. Permitted use

You agree to use the App only for lawful purposes and in accordance with the policies of the accounts and services to which you link 2FA codes.

You must not attempt to bypass the App’s security controls, interfere with its operation, unlawfully reverse engineer it, or use it to facilitate fraud or unauthorized access.

4. Responsibility for secrets and codes

You are solely responsible for safeguarding TOTP/HOTP secrets, backup codes, export passwords, and associated hardware keys.

Rosario Group LLC cannot recover lost secrets if you lose the device, delete the App without an encrypted backup, or lose recovery material. We recommend exporting with a strong password and keeping backup codes offline.

5. Optional SSO pairing

If you pair the App with a compatible SSO server, certain features (push approval, limited sync of SSO backup codes) depend on network and server availability.

Pairing can be removed in Settings. Misuse of paired devices may compromise corporate accounts; protect the device and the App lock.

6. Availability and changes

The App is provided “as is.” We may modify, suspend, or discontinue features, including beta or trial features, with or without reasonable prior notice when feasible.

We may update these terms. Continued use after reasonable notice of material changes constitutes acceptance of the updated version.

7. Limitation of liability

To the maximum extent permitted by applicable law, Rosario Group LLC and its affiliates shall not be liable for indirect, incidental, special, consequential, or lost-profit damages, nor for loss of data, account access, or benefits arising from use or inability to use the App.

Nothing in these terms excludes liability that cannot be limited by law.

8. Intellectual property

R-Guard, its name, logos, and original content are owned by Rosario Group LLC or its licensors. These terms grant only a limited license to use the App on compatible devices.

9. Governing law

Unless mandatory law provides otherwise, these terms shall be interpreted under the laws of the Commonwealth of Massachusetts (United States), without prejudice to non-waivable consumer rights.

Subject to the foregoing, state or federal courts located in Massachusetts shall be the competent forum for disputes arising from these terms or use of the App, to the extent permitted by applicable law.

10. Contact

For questions about these terms: contact Rosario Group LLC through official channels published on the company website (rosariogroupllc.com) or the App’s store listing.
