Effective date: October 27, 2026

This Privacy Policy applies to the app MultiCal ("the App"), published on Google Play by Doan Chon Ha ("I", "me", "the developer"). Contact: mrhatony@hotmail.com

Information I collect

I do not directly collect your name, email, or other personal information. Calculations are processed on your device only. However, third-party services used by the App (listed below) may collect certain data.

Advertising (Google AdMob)

MultiCal shows ads using Google AdMob. AdMob may collect and use your device's advertising ID, IP address, device and OS information, and app usage data to show ads, including personalized ads where permitted. You can reset your advertising ID or opt out of personalized ads in your device's Google settings.

• AdMob and Google privacy: https://policies.google.com/privacy

Other third-party services

The App also uses Google Play Services, which has its own privacy policy: https://policies.google.com/privacy

Log data

If the App has an error, third-party tools may collect technical data like IP address, device model, OS version, and time of use.

The App does not use cookies itself, but third-party ad services may use similar technologies to deliver and measure ads.

Security

I use reasonable means to protect your data, but no method of electronic storage is 100% secure.

Children's privacy

MultiCal is not directed at children under 13, and I do not knowingly collect personal information from them.

Changes to this policy

I may update this policy from time to time. Changes will be posted on this page.
