Privacy
Last updated: 10 September 2026
This page states plainly what Green Hub does with your data: what is kept, who else receives it, and how to erase everything.
In short: without an account, nothing leaves your device except the photo you send for identification. With an account, your garden is visible to you only. No data is sold or passed on for advertising.
Without an account: your trial stays on your device
You can identify a plant without creating an account. Your trial (the plant, its sheet, your photos) is then stored in this device's browser, and nowhere else. It is not sent to us, we cannot read it, and it disappears if you clear the site's data.
One necessary exception: the photo you submit goes to the identification services listed below, for as long as it takes to recognise the species and write the sheet.
With an account: what is stored
- your e-mail, name and profile picture, passed on by Google at sign-in;
- the region and hardiness zone you enter, to tailor the advice;
- your plants, their care sheets and their calendar;
- your photos, with the month and year stamped at the bottom of the image;
- your care log (watering, pruning, and so on);
- your conversations with the gardener.
Who else receives your data
Green Hub cannot recognise a plant on its own: it relies on outside services. Here is the complete list.
| Recipient | What it receives | Why |
|---|---|---|
| PlantNet (France) | your plant's photo | recognise the species |
| Google Gemini (Ireland / United States) | the photo and the plant name | write the care sheet, answer in the chat |
| OpenRouter, Anthropic | the same data, only if the first one fails | keep the service running when Gemini does not answer |
| Google (sign-in) | your e-mail, your name, your profile picture | sign you in, and tie your garden to your account |
| Google Analytics | anonymised visit statistics | count visits — only if you accept |
The three AI services are listed together because they stand in for each other: if the first does not answer, the request goes to the next. We cannot guarantee which one will handle a given photo.
For how long
Your data stays for as long as you keep your account. There is no automatic deletion after X months: you decide, and you can erase everything whenever you want from the section below.
Getting your data back, or deleting it
- Retrieve: from your account, “Export my data” hands you a JSON file with your plants, sheets, log and conversations, plus links to your photos.
- Delete: “Delete my account” erases the account, the plants, the photos (files included), the log and the conversations. It takes effect at once and cannot be undone.
- Delete a trial without an account: clear the site's data in your browser, or use “Delete my trial” on the trial page.
You can also write to the contact address in the legal notice with any question, or to exercise your rights of access, correction and objection.
