Privacy Policy.

Effective date: October 3, 2026   Last updated: October 11, 2026

This Privacy Policy applies to Gold Purity Lab (package name com.zetarank.goldpurity), listed on Google Play under the developer account name Outsource.

1. Information collected by the app

Gold Purity Lab provides workflows for gold-laboratory calculations, buying and selling records, receipts, reports, and related business tasks. According to the developer-provided Google Play Data safety disclosure, the app does not declare collection or sharing of user data. The app’s actual handling of entries depends on the storage, account, backup, and synchronization features included in the installed version. The current developer disclosure also says the app does not use advertising or analytics services.

Information entered for calculations and business records may be retained by the app so those features can work and records can be reviewed later. If an enabled feature transfers, backs up, or synchronizes information beyond the device, its handling should follow the behavior described in the app and the applicable Google Play Data safety disclosure.

2. How information is used and shared

The developer does not sell personal information. The current Google Play Data safety disclosure does not declare collection or sharing of user data. Any transfer associated with an account, backup, restore, or connected workflow must be considered in accordance with the behavior of the installed version and the relevant in-app disclosures.

3. Accounts, advertising, and analytics

The published feature description includes user-management features, roles, and controlled access where available in the installed version. Any user or account details entered for those features may be processed to provide the selected workflow. The developer’s current disclosure says the app does not display advertisements and does not use analytics or advertising SDKs.

4. Data storage and deletion

Calculation values and business records may be stored in the app so users can return to their work. Clearing app storage or uninstalling the app may remove locally stored records. Exported, printed, or backed-up copies may exist separately and may need to be removed from the relevant device or backup location. Back up important records before clearing storage or uninstalling. Information separately submitted through the website contact form is handled as described in Section 8.

5. Permissions and security

The app should request only permissions needed for the features being used. Review Android permission prompts and the app’s current information before connecting a compatible weighing scale or using an optional account, backup, or related workflow. Users should keep their device and operating system up to date and protect any credentials used in supported features.

6. Children’s privacy

Gold Purity Lab does not knowingly collect personal information from children or other users. If you have a concern about privacy, please contact us using the details below.

7. Third-party services

The current developer disclosure says the app does not use advertising or analytics services. If you follow an external link, such as a link to Google Play, that service is governed by its own privacy policy. Features that connect to a compatible Bluetooth scale or other selected service should be used in accordance with the relevant service and device information.

8. Website contact form

This policy describes the app. If you voluntarily contact us through the website, we receive the information you submit (such as your name, email address, subject, and message) so we can respond. Website contact messages are separate from data collected by the app.

9. Changes to this policy

We may update this Privacy Policy when the app or its data practices change. The latest version will be published on this page with an updated date.
