Last updated: June 8, 2026
Your privacy is fundamental to our design. Lịch Việt - Vietnam Calendar ("the App") is built to ensure that your personal data remains private and local.
Privacy at a Glance
1. Information Handling
Local-Only Information
The following information is stored exclusively on your device. We have no access to this data:
- Events & Reminders: Personal lunar anniversaries and custom scheduled notes.
- Work & Leave Planning: Your "Plan Day Off" selections and custom Leave Type configurations.
Data Collected by Third Parties
We work with certain service providers to support the App's functionality:
- Google AdMob: Collects Device Identifiers (IDFA) and Advertising Data to deliver personalized ads. This is only done with your permission via the App Tracking Transparency prompt.
- Apple StoreKit: Manages purchase history to unlock Premium features. Transactions are linked to your Apple ID but we do not see your payment details.
- Support Content: If you contact us via email, we collect your email address and message content to assist you.
2. Advertising & Measurement
The free version of the App uses AdMob. AdMob may collect and use certain data (such as Device Identifiers) for ad targeting, frequency capping, and measurement. If you upgrade to Premium, all ads are removed and tracking for advertising ceases.
