These terms of use apply to the use of the "90-Minute Sleep – Sunrise Alarm Clock" app, provided by LinguaFlow e.U. By downloading and using the app you accept these terms.
The app calculates optimal sleep and wake times based on 90-minute sleep cycles. It reminds you in time to go to bed and wakes you with a real system alarm. Optionally it simulates a natural sunrise through Philips Hue bulbs to wake you gently at the end of a sleep cycle. The sunrise automation runs directly on the Hue Bridge and works even when your device is switched off at night.
The alarm and reminders also work without Philips Hue.
The app offers an optional premium subscription:
The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Cancellation is possible at any time via the subscription management in the App Store (iPhone settings) or Google Play. An unused free trial expires when a subscription is taken out. The displayed prices may vary by country and store.
The app provides information and calculations based on the concept of 90-minute sleep cycles. This is for general orientation and does not constitute medical advice. The sleep review shown comes from Apple Health or Health Connect and is retrospective. If you have sleep disorders or health problems, please consult a doctor.
The app is provided "as is". LinguaFlow e.U. makes no guarantee of uninterrupted availability or freedom from errors. Compatibility with Philips Hue products depends on the respective firmware and hardware.
