Plant Mood · 2026-09-29
Plant Mood identifies your plant from the photos you take, reads its health and suggests how to care for it. This page explains what data we process and why.
Account
There is no sign-up. On first launch the app creates a random identifier and keeps it in your device's secure keychain. Our server stores only a one-way hash (SHA-256) of it. We do not ask for your name, email or phone number.
Photos
- Photos you take are used only to analyze your plant.
- Photos are sent to OpenAI for analysis, which processes them to provide the service.
- Scan photos are deleted after 60 days. The cover photo of a plant you save to your garden, and your readings, stay until you delete them.
- We do not use your photos for advertising or model training, and we do not sell them.
AI and your consent
Readings and Fern's answers are produced by OpenAI. Before any data is first sent to OpenAI, the app shows once what will be shared and asks for your permission; if you decline, no photo or message is sent. Your choice is kept on your device and is asked again if you reinstall the app or delete your data.
Ask Fern
- Messages you write to Fern are sent to OpenAI, together with the plant's name, placement (indoors/outdoors) and latest reading, to produce the reply.
- Chats are stored on our server until you delete them; Settings → Delete my data removes them all.
- With Premium Plus, once a week your plants' names, placements, latest health results and watering status are sent to OpenAI to write your weekly garden report.
- We do not use your messages or reports for advertising, and we do not sell them.
Weather guardian and location
- Location is used only if you turn on the weather guardian (frost, heat and storm alerts), and only for it. "Use my location" asks for approximate location while the app is in use; you can type a city instead (your device's own maps service turns the city name into a point).
- The location is rounded to 0.1° (about 11 km) before it leaves your device. Our server keeps that rounded point and the city name until you change it or delete your data (Settings → Delete my data).
- To get the forecast, only that rounded point is sent to the Norwegian Meteorological Institute (MET Norway, api.met.no); your identifier, plants and other data are not.
- Weather data comes from MET Norway and is used under the CC BY 4.0 licence.
Notifications
Watering reminders are scheduled on your device. If you allow it, Firebase Cloud Messaging is used to tell you a reading is ready.
Analytics
Firebase Analytics and Crashlytics help us understand how the app is used and fix crashes; Tenjin measures ad campaigns. If you decline tracking (ATT), your advertising identifier is not used.
Purchases
Subscriptions are handled by the Apple App Store or Google Play; we never see payment details. RevenueCat is used to verify subscription status.
Deleting your data
In the app, go to Settings → Delete my data to permanently delete your photos, plants and readings. An active subscription is cancelled through your store account.
