Information the app handles

Mystela does not receive the information that Mystela's watch faces (the "App") read to display your watch face. This information is processed on your watch only. Purchases and license checks, which involve KiezelPay, are described below.

To display the watch face, the App reads the following information on your watch and shows it on the screen:

This information is used only to show it on your watch screen. The App does not save it or send it outside your watch. For location, the App only reads the position your watch already has (its last known position and the location attached to Garmin's weather data); the App does not start GPS or location tracking on its own.

Your settings (such as color theme and data fields) are synced between your watch and your smartphone through Garmin's apps (Connect IQ, Garmin Connect). The operator of the App does not receive your settings. The App saves your settings on your watch. KiezelPay's library may also save licensing data on your watch, such as your trial or purchase status, a payment code, and an identifier used to recognise your device.

Purchases (KiezelPay)

The App offers a 24-hour free trial, after which a one-time purchase is required. Purchases, license checks, and refunds are provided by KiezelPay LLC ("KiezelPay").

The App includes KiezelPay's library, which communicates with KiezelPay's servers through your smartphone from time to time to check your trial or purchase status. For this, the library sends KiezelPay an identifier of your device, your watch model's part number, the App's product ID, and the library version. Neither the App nor KiezelPay's library sends your heart rate, location, settings, or other health and activity data to KiezelPay. If you make a purchase, KiezelPay also handles the email address you enter on its website. KiezelPay handles all of this information under its own privacy policy. Mystela does not control how KiezelPay handles it. For details, please see KiezelPay's Privacy Policy. For requests about purchase-related information, please contact KiezelPay.

Mystela can see basic purchase records in KiezelPay, such as the date and amount of a purchase, only to receive payouts and to help with support and refund requests.

Contact

If you contact Mystela by email, Mystela receives your email address and the information you include in your message. We use it only to respond to you and provide support, and keep it only as long as needed for that purpose or as the law requires. Please do not include health data or precise location information in your message.

For questions or requests about personal information that Mystela holds, please contact:
