Privacy Policy

1. Basic Policy

The App lets users manage information, photos, and care records for the plants they register. All features of the App are available without signing in, and in that case the data you enter is stored only on your device and is never sent to or stored on our servers or any third party's servers. Only if you optionally sign in (via Google, Apple, Facebook, or LINE) will your data also be synced to the cloud, as described in Section 3, so that it can be carried over when you change devices.

2. Information We Collect and How

The App does not collect contacts, device identifiers, or any other information not listed above.

3. Sign-In and Cloud Sync

The App lets you optionally sign in using a Google, Apple, Facebook, or LINE account. Signing in is not required, and if you do not sign in you can continue to use all features of the App as before.

If you sign in, your plant information, care records, and photos are stored on the servers of the cloud service "Supabase" (provided by Supabase, Inc.) that we use, separated per user, so that your data can be carried over even if you change devices or reinstall the App. Stored data is protected by access controls (Row Level Security) so that no third party other than us can access it. For information on how Supabase handles data, please see Supabase's Privacy Policy (https://supabase.com/privacy).

To provide the sign-in feature, information necessary for authentication (such as your email address) is sent to Google, Apple, Facebook, or LINE's authentication service. Please refer to each provider's own privacy policy for how they handle this information.

If you sign out after having signed in, cloud syncing stops, but the data already stored in the cloud is not deleted. If you would like your cloud data deleted, please use the "Delete Account" option in the App's settings screen, or contact us using the information in Section 10.

4. Disclosure to Third Parties (AI Features)

4-1. AI Plant Identification

Only if you use the App's "Identify with AI" feature, the photo of the plant you took is sent to the plant identification service "Pl@ntNet" (run by the Pl@ntNet project). This is necessary to obtain identification results, and we do not store or otherwise reuse the images sent for this purpose. For information on how Pl@ntNet handles data, please see Pl@ntNet's Privacy Policy (https://plantnet.org/en/privacy-policy/).

4-2. AI Health Check

Only if you use the App's "AI Health Check" feature, the photos you take (up to three) and a summary of how that plant has been cared for are sent to an API provided by OpenAI, Inc.

The care summary is limited to a predefined set of items: the species name, days since you added the plant, whether it is kept indoors or outdoors, the name of its location, the watering interval, days since the last watering, fertilizing and repotting, the number of waterings in the last 30 days, the season, light check readings, and the description of symptoms you enter on that screen. Your name, email address, address, information about your friends, the nickname you gave the plant, its purchase price, and notes unrelated to the check are not sent.

Photos sent for a health check are not stored on our servers (cloud storage). They are saved as ordinary plant photos, as described in Section 3, only if you choose "Save as a growth record" on the result screen. The text of the result is stored in the cloud only if you are signed in.

For information on how OpenAI handles data, please see OpenAI's Privacy Policy (https://openai.com/policies/privacy-policy).

4-3. Weather-Based Watering Adjustment

Only if you enable the "adjust watering interval based on the weather" setting for a plant you keep outdoors, your location (latitude and longitude) at the time you save that setting is sent to the weather information service "OpenWeatherMap" (provided by OpenWeather Ltd.). This is necessary to retrieve the rainfall forecast for that location and reflect it in the watering interval.

Your location is retrieved only once, at the time you save the setting; we do not continuously track it. We do not store or otherwise reuse the location data that is sent. For information on how OpenWeatherMap handles data, please see OpenWeather's Privacy Policy (https://openweather.co.uk/privacy-policy).

If you do not use these features, no photo data or location data is sent externally.

5. Information Related to Subscriptions (Pro Plan)

Subscribing to the Pro plan is handled through Apple's App Store payment system. We do not collect or retain payment information (such as credit card numbers); it is managed by Apple Inc.

We also use RevenueCat, Inc.'s service to manage subscription status (such as expiration dates). Purchase-related information (purchase date, expiration date, an anonymous device identifier, etc. — not including credit card information) is sent to RevenueCat, Inc. For information on how RevenueCat handles data, please see RevenueCat's Privacy Policy (https://www.revenuecat.com/privacy).

6. Cookies, Tracking Technologies, and Usage Analytics

The App is a native application and does not use cookies. We do not perform any tracking for advertising purposes.

To improve the App, we use services provided by Amplitude, Inc. to analyze how features are used. The information sent consists of the type of action taken in the App (signing in, registering a plant, recording care, viewing the subscription screen, making a purchase, and similar actions), attributes accompanying that action (the sign-in method used, the type of care recorded, the name of the screen used, and the plan type selected), and device and app information (app version, OS version, device model, language, country or region inferred from your IP address, and an anonymous identifier). We also send your current plan (Free or Pro), the number of plants you have registered, your notification permission status, and whether you are signed in, in order to categorize usage.

Content you enter or capture yourself — plant nicknames, photos, notes, purchase amounts, and places of purchase — as well as your name, email address, and any information about your friends, is not sent. We also do not perform screen recording (session replay).

For details on how Amplitude handles this information, please see Amplitude's privacy policy (https://amplitude.com/privacy).

7. Disclosure and Deletion of Information

If you are not signed in, your plant information and photos are stored only on your device, so deleting (uninstalling) the App also deletes this information from your device. If you are signed in, you can delete the information stored in the cloud by using the "Delete Account" option in the App's settings screen. For information sent to external services under Sections 4 and 5, please contact each provider using the method described in their own privacy policy.

8. Use by Minors

The App is provided in accordance with the age rating assigned on the App Store.

9. Changes to This Policy

Except where otherwise required by law or by this Policy, we may change the contents of this Policy without notifying users individually. The revised Privacy Policy will take effect once it is posted within the App or at a location we designate.
