Privacy policy
This privacy policy applies to the Q Calendar app (the “Application”) for mobile devices, provided by Regnum Digital Company (the “Service Provider”).
Q Calendar is designed to be a local-first calendar. Your calendar content, stickers, and most app data are stored on your device.
What the Application collects
The Application may collect limited analytics information about how the app is used. This may include:
- app opens
- screen usage
- limited feature usage events such as sticker import, sticker management, and event save or delete actions
- device and app information provided by the platform or analytics SDK
The Service Provider does not use analytics to collect the contents of your events, notes, sticker names, category names, or other user-written text.
The Application does not collect precise location data.
Photos, files, and local access
The Application may ask for access to photos or files when you choose to import stickers.
This access is used only to let you:
- pick images from your photo library
- pick image files from your documents or Files app
- import images from the local
/stickersfolder used by the Application
Imported sticker images are copied into the Application’s local storage on your device so they can continue to work inside the app.
How your data is used
The Service Provider uses information only for purposes such as:
- operating core app features
- storing and organizing your local calendar and sticker data on your device
- improving stability and product quality
- understanding broad usage patterns through limited analytics
Third-party services
The Application uses third-party services that may process limited technical or analytics data according to their own policies.
Current third-party services include:
If the Application adds or removes third-party services in the future, this page will be updated to reflect that.
Data sharing
The Service Provider does not sell your personal data.
The Service Provider may disclose limited information only:
- as required by law
- to protect rights, safety, or security
- to service providers acting on the Service Provider’s behalf under appropriate obligations
Data retention
Most Application data is stored locally on your device.
Limited analytics data collected through third-party services is retained according to those providers’ policies.
If you uninstall the Application, locally stored app data may be removed from your device, subject to your platform’s normal uninstall behavior.
Children
The Application is not directed to children under the age of 13, and the Service Provider does not knowingly collect personal information from children under 13.
If you believe a child under 13 has provided personal information, please contact the Service Provider so appropriate action can be taken.
Security
The Service Provider takes reasonable steps to protect information processed through the Application and to keep the Application’s data handling limited and practical.
Because much of the Application’s data is stored locally, the security of your device also matters.
Changes
This Privacy Policy may be updated from time to time. Updates will be reflected on this page.
This privacy policy is effective as of 2026-04-20.
