Effective date: November 16, 2025
1. Introduction
zv calculator (“we”, “our”, or “us”) provides the zv calculator mobile application (“App”). This Privacy Policy explains how we collect, use, disclose, and protect information when you use the App.
2. Information we do NOT collect
The App is designed to work offline and does not require a user account. We do not collect personally identifiable information (PII) such as name, email address, phone number, or precise location.
3. Information we may collect automatically
To improve the App and monitor stability, we may collect limited, non-identifying technical information such as:
Device type and operating system version
App version and crash logs
Anonymous usage statistics (e.g., how often features are used)
This information does not identify you personally.
4. Analytics and third-party services
If you choose to enable optional services (for example, crash reporting or analytics), those services may collect anonymous usage and crash data. Examples of such third-party providers include Google Firebase / Google Analytics. Their collection is governed by their own privacy policies.
5. Permissions
The App requests only the permissions needed for its basic function. If the App requests any additional permissions (for example, access to storage), these will be clearly explained to you at runtime and only used to support the requested feature.
6. Advertising
The current release of zv calculator does not display ads. If ads are added in future versions, we will update this policy and disclose the ad networks used and what information they collect.
7. Children
The App is not intended for children under 13. We do not knowingly collect information from children under 13. If we learn we have inadvertently collected such information, we will take steps to delete it.
8. Your rights
Depending on your location, you may have rights to access, correct, or delete your personal data. Since we collect little or no personal data, most requests can be fulfilled quickly. To exercise your rights, contact us (see Section 10).
9. Data retention and security
We retain technical and analytics data for as long as necessary to improve and support the App. We implement reasonable security measures to protect data, but no transmission or storage is fully secure. We cannot guarantee absolute security.
