By accessing or using CalcVault, you acknowledge that you have read, understood and agreed to these Terms of Service. If you do not agree with these terms, please discontinue using the application.

2. Description of Services

CalcVault provides a private storage application that allows users to organize and protect personal content, including photos, videos, documents, files, notes, passwords and card information.

Features may include calculator-style access, encrypted storage, biometric authentication, Intruder Selfie, Screenshot Protection, Recovery Mode, Recycle Bin and Stealth Mode.

Features may vary depending on the device, Android version and application version.

3. User Responsibilities

You are responsible for maintaining the security of your device and protecting access to your CalcVault application.

You agree not to use CalcVault for illegal activities, unauthorized access, or storing or distributing content that violates applicable laws.

You are responsible for the content you store within the application.

4. Private Vault and Data Storage

CalcVault is designed to store private content locally on your device rather than uploading it to an online storage service operated by CalcVault.

You are responsible for maintaining your device and ensuring that important files are backed up where appropriate.

Uninstalling the application, resetting your device, clearing application data or experiencing device failure may result in permanent data loss.

5. Encryption and Security

CalcVault uses encryption to provide an additional layer of protection for supported files stored in the private vault.

Although we implement security measures, no application or storage system can guarantee absolute security.

Users should keep their device secure and avoid sharing their vault credentials or access methods.

6. Photos, Videos and File Management

CalcVault allows users to import, organize and manage supported photos, videos and other files inside their private vault.

Users are responsible for ensuring they have the necessary rights to store and manage the content they import.

7. Recovery Mode and Recycle Bin

CalcVault provides Recovery Mode and Recycle Bin features to help users recover supported data when available.

Recovery functionality may depend on the device, application version, storage conditions and availability of the original data.

We cannot guarantee successful recovery of every deleted, corrupted or lost file.

8. Biometric Authentication

CalcVault may support biometric authentication using the device's available biometric security features.

Biometric functionality depends on device compatibility and the security settings configured on the device.

9. Intruder Selfie and Stealth Mode

CalcVault may provide Intruder Selfie functionality under configured conditions to capture images during certain unauthorized access attempts.

Stealth Mode allows users to change the visible application icon to supported alternatives.

Users are responsible for complying with applicable laws when using these features.

10. Data Loss and Recovery Limitations

CalcVault is not responsible for data loss caused by device damage, factory resets, application uninstallation, operating system failures, unauthorized access, user actions or other circumstances beyond reasonable control.

Users are encouraged to maintain independent backups of important information.

11. Disclaimer of Warranties

CalcVault is provided on an "as is" and "as available" basis without warranties of uninterrupted operation, error-free performance or guaranteed data recovery, to the extent permitted by applicable law.

12. Limitation of Liability

To the extent permitted by applicable law, the developer shall not be liable for indirect, incidental or consequential damages resulting from the use or inability to use CalcVault, including data loss.

Nothing in these terms excludes liability that cannot legally be excluded under applicable law.

13. Changes to These Terms

We reserve the right to update these Terms of Service when necessary. Updated terms will be published on this page, along with a revised effective date.

Continued use of CalcVault after changes become effective constitutes acceptance of the updated terms, where permitted by applicable law.
