桃月 Momotsuki
Privacy Policy
Effective date: 2026-11-04
This policy explains how the Momotsuki app (iOS, iPadOS, Android) and this website, momotsukiapp.com, handle your information. In short: the app has no accounts, we run no server that stores user data, and we do not collect your personal data.
What we don't collect
The app has no sign-up or login, no ads, no analytics and no crash reporting. We cannot see your events, journal, photos, health and cycle records, birthday or location.
Data stored on your device
Events, journal entries (text, photos, mood, place names), women's health and cycle records, birthday and zodiac settings, and your weather city list are stored only on your device.
Women's health and cycle data is never included in backups, exports or sharing, notifications, or sync.
System backup: if you have iCloud or Google device backup turned on, events and journal entries may be backed up with your device and kept by Apple or Google under their policies, without passing through us. Health data, birthday settings and weather cities are excluded.
Journal export files are saved and shared by you.
Weather and hazard information (off by default)
The app connects to the internet only after you turn on the switch on the Weather tab. Turning it off stops all requests immediately and deletes downloaded weather caches.
Forecasts: the approximate coordinates of a city (about 10 km precision) are sent to the weather provider Open-Meteo to fetch local weather — only for the city you are viewing and the two next to it. No account or device identifier is sent, but the provider can see your IP address.
City search: the city name you type is sent to Open-Meteo's place-name search.
Alerts and earthquakes: complete public feeds are downloaded from official agencies such as the Japan Meteorological Agency, the US Geological Survey (USGS), the Hong Kong Observatory, Taiwan's Central Weather Administration and the Met Office, and filtered on your device; your location is not sent. US National Weather Service (NWS) alerts can only be queried by location, so for US cities the same approximate coordinates are sent to the NWS.
These agencies are independent data providers and handle request logs under their own policies.
Device features we use
Location: obtained once, approximately, only when you tap the location button, for a journal place or a weather city; it is rounded to about 10 km before it is saved.
Microphone and speech recognition: used only while you tap the microphone, to turn speech into journal text; recordings are not kept. Recognition runs on the device where supported; otherwise the system speech service (Apple or Google) processes it under their privacy policy.
Camera and photos: used only when you add a photo; photos are kept inside the app.
System calendar: read or written only after you turn it on, processed on the device.
Notifications: event reminders are local notifications on the device, with no server involved.
Deleting your data
There is no account, so there is nothing to request. Uninstalling the app deletes all of its data on the device, and you can delete individual records in the app. Copies in system backups are managed in your iCloud or Google account settings.
Children
The app is not directed to children under 13, and we do not knowingly collect children's information.
This website
momotsukiapp.com uses Google Analytics 4 to count visits (page views, approximate region, device type and similar), and Google uses cookies for this. The site is served through Cloudflare, and the server keeps standard access logs (IP address, time, page visited, browser information) for security and statistics. You can refuse analytics through your browser settings or the Google Analytics opt-out add-on.
Changes and contact
If this policy changes in substance, we will update this page and its effective date; if a new feature needs additional data, the app will ask for your consent first.
