Privacy Policy – Lịch Âm Việt
This Privacy Policy explains how CellHubs ("we", "us") handles information in connection with Lịch Âm Việt (the app). Lịch Âm Việt stores your events on your device and, if you choose, in your calendar accounts. It asks only for permissions its features need.
Information we handle
- Calendar events you create or choose to sync
- Basic device and app diagnostics (crash reports, usage statistics)
- Notification token used to deliver reminders
We do not sell your personal information. Information is used only to provide, maintain and improve Lịch Âm Việt, to show relevant advertising where the app is ad-supported, and to diagnose crashes.
Permissions
- Calendar – read, create and edit on-device events
- Notifications – deliver reminders for important dates
- Background refresh – keep dates and widgets up to date
Permissions are requested only when needed by a feature you use.
Third-party services
Lịch Âm Việt uses third-party services that may collect information used to identify you. Their handling is governed by their own privacy policies:
- Google Play Services
- Firebase Analytics
- Firebase Crashlytics
Account & sync
If you enable cloud synchronisation, your event data is stored securely so it can be available across your devices. You may request deletion at any time by emailing us.
Log data
If an error occurs, third-party tools may collect log data such as your IP address, device model, operating system version, app configuration, and the time and date of use.
Cookies
Lịch Âm Việt does not use cookies itself. Embedded third-party code may use cookies or similar identifiers to improve its own services.
Security
We use commercially reasonable measures to protect information. No method of transmission or storage is 100% secure, so we cannot guarantee absolute security.
Data retention & deletion
Data stored on your device is removed when you uninstall Lịch Âm Việt. To request deletion of any data we hold, email cellhubsapp@gmail.com.
Children’s privacy
Lịch Âm Việt is not directed to children under 13 and we do not knowingly collect their personal information. If you believe a child has provided us information, contact us and we will delete it.
Links to other sites
The service may link to sites we do not operate. We have no control over and assume no responsibility for their content or practices.
Changes to this policy
We may update this policy from time to time. Changes are effective when posted on this page, and the “last updated” date above will change.
