Privacy Policy
ChibyooAlarm
Last updated: August 15, 2026
1. Introduction
ChibyooAlarm ("we", "our", "the app") is developed by Chibyoo, an independent developer. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your personal information.
By using ChibyooAlarm, you agree to the practices described in this policy.
2. Data We Collect
2.1 Data You Provide
- Nickname and avatar — set voluntarily in your profile
- Date of birth — used solely to determine your zodiac sign for the optional horoscope feature
- Barcodes and NFC tags — stored locally on your device
2.2 Data Collected Automatically
- Device identifier (Install ID) — a randomly generated anonymous identifier stored on your device. Used to identify your device for security verification (App Attest) and optional social features. This identifier is not linked to your Apple ID or personal identity.
- Wake-up statistics — time of alarm dismissal, mission completion time, snooze count. If you enable Global Stats or Wake-up Partners, aggregated anonymous statistics are sent to our server.
- Alarm schedule — alarm time and weekdays, sent to our server only if Wake-up Partners is enabled.
- Crash reports and diagnostics — collected via Firebase Crashlytics to improve app stability.
- App launch events — anonymous telemetry to understand general usage patterns.
2.3 Health Data
- Sleep data — read from Apple Health (HealthKit) with your permission. Used only to display sleep statistics within the app. This data is never transmitted to our servers or any third party.
2.4 Location Data
- Approximate city — determined via your IP address using the ipapi.co service when you open the Morning screen. This is used solely to fetch local weather. We do not store your IP address or precise location. You can manually set your city in the app to avoid this.
- If you grant location permission, your device's GPS coordinates are used to fetch weather via Apple WeatherKit. Location data is not stored or transmitted to our servers.
