Leafday Privacy Policy

English version of the policy above. If the two differ, the Japanese text is authoritative.

Your data

Leafday ("the app") stores your plants' names, photos, watering intervals and when you watered them only on your device, in the app's own container. The app does not send them to the developer's servers and does not share them with third parties. There is no account and no advertising.

Weather-based watering adjustments

Only if you turn on "Weather adjustments" in Settings, the app uses your device's approximate location (rounded to about 11 km) to get local rainfall and temperature from Apple's weather service (WeatherKit). The location is sent to Apple only to look up the weather and is never sent to the developer's servers. The rounded location and the weather are stored only on your device. You can revoke location access at any time in Settings › Leafday › Location.

Anonymous usage

To improve the app, the following anonymous records are sent to the developer's server.

The kind of action taken, such as opening the app
Which screen showed the Pro offer, and which feature triggered it
That a widget was displayed, and its size
The number of plants (never their names or photos)
App version, OS version and language setting
A random identifier generated on the device (deleted when you delete the app)
The country of the connection (IP addresses are not stored)

The following are never sent:

Your content — plant names and photos
Contact details such as name, email address, phone number or postal address
Advertising identifier (IDFA) or device identifier (IDFV)
Location
IP address

These records are not used to serve or measure advertising, are not sold or given to data brokers, and are not linked with any third party's tracking data. No third-party analytics SDK is included.

You can stop sending at any time from Settings (gear) > Privacy > "Share anonymous usage". Stopping also deletes any records not yet sent from the device.
