Privacy Policy

Zyn Minimalist Bookkeeping App highly values your privacy. Our core philosophy is: complete data privatization, and we never collect your personal financial information. All data is stored only on your local device, and the developer cannot access your billing details.

We only collect a minimal amount of anonymous technical statistics to improve product quality and user experience, specifically as follows:

What We Collect

App crash information (automatically collects unhandled exceptions)
Feature usage statistics (success and failure rates of each feature)
App lifecycle events (startup, foreground, background switching)
Page open times
Error logs (such as non-critical errors like database operation failures)
Device information (basic info such as platform and version)

What We Do Not Collect

Specific amounts or contents of your bills

Purpose of Data Collection

Only for analyzing and improving product features and performance
To ensure app stability and security
To identify and fix potential issues

All data is collected anonymously and will never be sold, rented, or disclosed to third parties. Your billing data is always stored only on your local device. If you uninstall the app, all local data will be deleted and cannot be recovered by the developer.

If you have any questions, feel free to contact us.
