Privacy policy

Overview

Most Thermia data stays on your device. Data leaves the device only when you enable an Apple service such as iCloud or Apple Health, use TestFlight feedback, or choose to contact support.

Data stored by Thermia

Thermia may store the following information to provide app features:

• Mug name, identifier, model, firmware information, and connection state.
• Temperature, target temperature, battery, and liquid-state readings.
• Presets, schedules, temperature history, drink sessions, caffeine estimates, and app preferences.
• Pending commands used by companion features such as Apple Watch.

Bluetooth

Thermia uses Bluetooth to find and control compatible Ember mugs. Bluetooth communication occurs locally between your Apple device and your mug. Thermia does not use Bluetooth to track your location.

Apple Health

Apple Health support is optional and write-only. If you enable it, Thermia can write a caffeine entry that you confirm after a completed drink session. Thermia does not request Apple Health read access and does not import Health records into the app.

You can review or revoke Health permission through the Health app or iOS Settings.

iCloud sync

iCloud sync is optional and uses your Apple ID. When enabled, supported presets, schedules, temperature readings, drink sessions, and preferences may sync through Apple’s iCloud infrastructure. Apple Health records are not read or synced by Thermia.

Support, diagnostics, and TestFlight

Thermia does not automatically send diagnostics to the developer. If you choose to contact support, the information you include may contain app version, device model, OS version, Bluetooth state, and mug state.

During beta testing, TestFlight feedback may include screenshots, comments, crash information, app version, build number, device and OS details, and tester contact information when available. Apple processes that feedback under its own terms and privacy policy.

Export and deletion

Thermia can export supported data such as temperature history and drink sessions. Removing Thermia from a device deletes its local app data. If you enabled iCloud sync, you may also need to remove synced Thermia data through your iCloud settings.

Tracking, advertising, and children

Thermia does not track you across apps or websites, sell your data, or use advertising tools. Thermia is not designed for children and does not knowingly collect personal information from children.

Independent app and policy changes

Thermia is not affiliated with, endorsed by, or sponsored by Ember Technologies, Inc. Ember is a trademark of its owner. This policy may be updated as Thermia changes; the effective date above will change when material updates are made.
