Frost Alert Privacy Policy

Last updated: October 8, 2026

Data controller

Frost Alert is published by Yumozu. For any question concerning your personal data, contact .

Data we use

When you set up a location to monitor, its name, geographic coordinates, selected alert thresholds, language and temperature unit are sent to and stored on our server to perform weather checks and send alerts even when the app is not open.

A Firebase technical token unique to the app installation is also stored to deliver notifications to your device. The app does not access your phone’s GPS location and does not create a user account.

Purpose and legal basis

This information is used only to show the forecast for the selected location and send the frost alerts you request. Processing is necessary to provide the service you configure.

Service providers

Data is processed by a server hosted by OVHcloud. Forecasts and location searches are provided by WeatherAPI.com, which receives the coordinates or location search required. Notifications are delivered through Firebase Cloud Messaging, a Google service, which processes the technical token and notification content to deliver it to your device.

Retention

The alert configuration associated with the Firebase token is retained while the app remains active on the device so that requested alerts can be delivered. It is deleted when a token becomes invalid and may be deleted on request using the contact address. Weather responses may be cached for up to 90 minutes. Technical hosting logs may contain the IP address, date and requested URL, depending on the host’s settings and security obligations.

Local app data is removed when you clear the app’s data or uninstall it.

Security and sharing

Communication between the app, our server and providers uses HTTPS. No data is sold, used for advertising or shared for profiling purposes.

Notifications

Notification permission is used solely for frost-risk alerts. You can withdraw it at any time in Android settings.

Your rights

You may request information about the processing of your data or exercise applicable rights of access, rectification, erasure, restriction and objection by contacting the address above. If you are in the European Union, you may also lodge a complaint with your local data protection authority.

Changes to this policy

This policy may be updated if the application’s operation or service providers change. The date shown at the top of this page will be updated accordingly.
