Contact support
Email support@kyltherm.com. Include the email address connected to your Kyltherm account and a short description of the issue. Do not email passwords, full payment-card details, or heart-rate export files unless we specifically ask for them through a secure process.
Subscriptions and billing
Kyltherm subscriptions are billed by Apple’s App Store or Google Play. The price and trial eligibility shown by the native store purchase screen are the controlling terms.
- Use Restore Purchases in Kyltherm if paid access is missing.
- Use Manage subscription in Kyltherm or your store account to cancel or change the subscription.
- Deleting the app or your Kyltherm account does not cancel a store subscription.
- Refund requests are normally handled by the store that processed the purchase.
Bluetooth heart-rate monitor
Wake or wear the sensor before scanning, allow Bluetooth permissions, and make sure another fitness app is not already holding the connection. Kyltherm supports monitors that broadcast the standard Bluetooth Heart Rate Service. Recording heart rate is optional; the timer works without it.
Exporting your data
Open Profile → Your data to export a summary CSV or full JSON file. Each session with recorded heart rate also offers a heart-rate CSV. Structured exports do not include photo files, so save any photos you want to retain separately.
Privacy requests
You can export data or delete your account directly in Kyltherm. For access, correction, restriction, objection, portability, or another privacy request, email support@kyltherm.com. We may verify that you control the account before acting on a request.
