Liver Volumetry Privacy Policy

Effective date: 14 May 2026

Liver Volumetry is a clinical calculator app for estimated standard liver volume and PDF report preparation.

Information We Collect

The calculator can be used without creating or signing in to an account. If you choose to sign in, the app uses Firebase Authentication to support email, Google, and Apple sign-in. Authentication may provide account identifiers such as user ID, email address, display name, and provider information.

The calculator fields and generated reports are entered by the user for calculation and report output. Do not enter unnecessary personally identifiable information unless it is required for your own clinical workflow.

How Information Is Used

Account information is used to authenticate access and maintain basic user account records. Calculator values are used to calculate liver volume estimates and generate local PDF output.

Data Storage

Firebase may store user account metadata for authenticated users. Generated PDF reports are produced at the user's request and handled by the device, browser, print, share, or download flow.

Signed-in users can open the in-app Account screen to view the active account, sign out, or permanently delete the account.

Medical Disclaimer

Liver Volumetry is an aid for calculation and documentation. It is not a substitute for professional medical judgment, institutional protocols, or independent verification of clinical measurements.

Third-Party Services

The app may use Firebase services from Google for authentication, hosting, and account metadata. Sign-in providers may include Apple and Google.
