Privacy Policy for CalcVault

Last Updated: September 1, 2026

CalcVault (“we,” “our,” or “us”) respects your privacy. This Privacy Policy explains what information CalcVault collects, how we use it, and how your files and media are protected when you use the CalcVault application.

1. Information We Collect

CalcVault is designed to work primarily offline and does not require you to upload your personal files or media to our servers.

We may collect the following information in specific circumstances:

App Crash Information

We may collect information related to application crashes and errors. This may include technical information such as:

• Crash logs and error reports

• Device information

• Android/API version

• App version

• Other technical information necessary to diagnose and fix crashes

This information helps us identify problems, improve app stability, and provide a better experience for our users.

Feature Requests and Bug Reports

If you voluntarily choose to submit a feature request, bug report, feedback, or contact us through the app, we may collect:

• Your email address

• Your feature request, feedback, or bug report

• Device API/Android version

• Device name

• Other technical information that you choose to provide or that is automatically included with your report

We use this information solely to understand reported issues, respond to your request when necessary, improve CalcVault, and make the app more reliable for our users.

Providing a feature request or bug report is voluntary.

2. Your Videos, Photos, Files, and Media

Your private content stays on your device.

Any videos, photos, files, documents, or other media that you lock or protect using CalcVault are not uploaded to our servers or stored online by us.

CalcVault is designed to keep your protected content locally on your device and available offline.

We do not use your locked videos, photos, files, or media for advertising, analytics, or any other purpose.

We do not have access to the contents of your locked files or media through CalcVault's normal operation.

3. Offline Operation

CalcVault is designed to provide its core vault functionality locally on your device. Your protected content does not need to be stored in an online cloud service operated by us.

If you use a feature that requires sending information to us, such as submitting a bug report or feature request, only the information necessary for that communication is sent.

4. Encryption and Security

CalcVault uses encryption and security mechanisms to protect the files and media that you choose to lock within the application.

The protected content is intended to remain securely stored on your device rather than being uploaded to our servers.

However, no security system can guarantee absolute protection under every circumstance. Users should also maintain appropriate security on their device, including a secure device lock, and avoid sharing their device credentials or vault credentials with others.

5. How We Use Collected Information

Information collected through crash reports and voluntarily submitted feedback may be used to:

• Fix crashes and bugs

• Improve app performance and stability

• Develop and prioritize new features

• Understand technical problems affecting users

• Respond to feature requests or bug reports

• Improve the overall CalcVault experience

We do not sell your personal information.

6. Data Sharing

We do not sell or rent your personal information.

We do not intentionally share your locked photos, videos, files, or other protected media with third parties because this content remains stored locally on your device and is not uploaded to our servers through CalcVault.

Technical information associated with crash reports or voluntarily submitted feedback may be processed by services used to help us diagnose crashes and improve the application, where applicable.

7. Data Retention

We retain crash information and information submitted through feature requests or bug reports only for as long as reasonably necessary to fulfill the purposes described in this Privacy Policy, improve CalcVault, resolve issues, and maintain appropriate records.

Your locked files and media are not retained on our servers because we do not store them online.

8. Your Responsibility

Because your protected files and media are stored locally on your device, you are responsible for maintaining access to your device and CalcVault.

If your device is lost, damaged, reset, or the CalcVault application data is deleted without an appropriate backup, your protected content may become inaccessible or may be lost.

We strongly recommend maintaining a secure device and following any backup instructions provided within CalcVault.

9. Children's Privacy

CalcVault does not knowingly collect personal information from children in violation of applicable privacy laws. If you believe that a child has provided personal information to us, please contact us so that we can review and take appropriate action.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to CalcVault, our practices, or applicable legal requirements.

When we make changes, we will update the “Last Updated” date at the top of this Privacy Policy.

We encourage you to periodically review this Privacy Policy to stay informed about how CalcVault handles information.
