Privacy policy
Last updated: 5 October 2026
Gnomie is a small app made by Glide Marketing Ltd (UK), run by Mike McDonnell. We collect as little data as possible. This page is an honest account of what leaves your phone, when, who processes it and why.
In short
- Your plants, photos, care logs and preferences are stored on your phone.
- When you use an AI feature, the photo is sent to the Gnomie API (
landscapes-api.vercel.app), which asks OpenAI and Pl@ntNet on your behalf. To answer common cases faster, a short written description of the photo (never the photo itself) may also go to TypeSafe AI. None of it is stored after the answer comes back. - Sign in with Apple is optional. If you use it, we keep an anonymous Apple identifier so we can recognise you.
- No analytics, no advertising, no tracking across apps.
- You can wipe everything on your phone in More, then Account & data, then Reset all data.

What we collect, when, and why
Location
If you grant location permission, the app reads your coordinates once and turns them into a UK postcode for the weather. You can type a postcode instead and skip the permission. The postcode stays on your phone and is used to ask Open-Meteo (api.open-meteo.com) for your local forecast. They receive only coordinates and a date range. Their terms: https://open-meteo.com/en/terms.
We do not track your location, and we do not store coordinates on any server we control.
Photos and the AI features
When you take or pick a photo, the app resizes it to 1024px wide, compresses it to JPEG and keeps it in its private storage on your phone. The photo only leaves your phone when you use an AI feature: identifying a plant, adding a plant from a photo, Health Check or Spot Check. It then goes to the Gnomie API, which uses these services to answer:
| Service | What it receives | Why |
|---|---|---|
OpenAI (api.openai.com) | The photo | To identify the plant, judge its health and write the advice you see. Also to write the short description used by TypeSafe AI. |
Pl@ntNet (my-api.plantnet.org) | The photo | A specialist plant identification service, used as a second opinion on the species when you identify a plant or run a Health Check. |
TypeSafe AI (api.typesafe.ai) | A short text description of the photo (for example “lobed leaves, yellow flowers, black spots on the lower leaves”), Pl@ntNet's species guesses, and the list of plants or problems to choose from. Never the photo, your device token or anything about your account. | A fast decision model that picks the plant or problem from our list, so common cases are answered in seconds. |
We do not write your photo, or the description of it, to any database, log or storage we control. For each request we keep a short technical record (which plant or problem was picked, how confident each step was, and how long it took) so we can check the fast answers are accurate. That record holds no photo, no description, no device token and no account details.
Each service's own terms apply to what it receives: OpenAI https://openai.com/policies/api-data-usage-policies, Pl@ntNet https://my.plantnet.org, TypeSafe AI https://typesafe.ai.
Plant names for care plans
When you add a plant, its name (for example “Monstera, houseplant”) is sent to the Gnomie API to fetch a care plan. Care plans are stored per plant type, not per person, so the stored plan says nothing about you.
Device identifier
The app creates a random token on first launch and sends it with each request to the Gnomie API, which uses it to count your daily AI allowance and to block abuse. It is not linked to your identity unless you sign in with Apple (see below).
Sign in with Apple (optional)
If you sign in (More, then Account & data), Apple gives us an anonymous identifier unique to Gnomie, and, the first time only and only if you agree, an email address (which may be Apple's private relay address) and your name. We store these in a Supabase database in the EU, linked to your device token, so we can recognise you and so Gnomie Pro follows your Apple ID to a new phone.
We never pass your Apple identifier, email or name to an advertiser, analytics service or data broker. Signing out removes the session from your phone. To delete the server record, email us from the address linked to your Apple ID.
Gnomie Pro
Apple handles every purchase through the App Store. RevenueCat, which checks your subscription, receives your anonymous device token, not your name or email.
Feedback
If you send feedback (More, then Send Gnomie feedback), we store what you write, the name you choose to give, any screenshots you attach and, if you are signed in, your Apple identifier, in the same EU Supabase database, so we can read it and reply.
Notifications
Reminders are scheduled by iOS on your phone. No push token is sent to any server.
What we don't collect
- No advertising IDs (IDFA) and no tracking across apps or websites.
- No analytics events (screen views, taps, sessions).
- No crash reports.
- No name, email, address or phone number, unless you sign in with Apple and Apple shares them, or you put them in feedback.
