What we keep
Written to match what the code actually does, rather than to cover every eventuality. Last updated 2026-09-05.
The short version
The Lawn Tells takes photographs of your lawn and a location, and returns a ranked guess at what is wrong with it. To do that it sends your photographs to an AI model and your coordinates to several weather and soil services. It keeps the result so the app can be measured against reality, which is the whole point of the project.
There are no accounts, no advertising, and nothing is sold. We do not know who you are.
Your photographs are only stored if you tick the box. The diagnosis itself, your approximate location and anything you typed are stored either way, and you can delete all of it whenever you like.
What is stored
| Your photographs | Only if you ticked the box. Otherwise they are never written down. |
| Where the lawn is | Coordinates, to within about a metre, and the nearest town name. |
| What you told us | Grass type and any notes you typed. |
| The diagnosis | The ranked candidates, the plan, and the weather and soil at the time. |
| How it went | How long it took and how much the model wrote, so cost and speed can be watched. |
| Your answer, if you give one | Whether the diagnosis was right, and what it turned out to be. |
| Your email address | Only if you asked to be reminded. |
| Which screens were used | Anonymous counts tied to a random id for the browser, not to you. |
Who else receives it
The app cannot work without sending some of this to other services. Your coordinates in particular leave here four different ways, and it would be misleading not to say so.
| Who | What they get | Why |
|---|---|---|
| Anthropic | Your photos, your notes, and the weather and soil summary | Producing the diagnosis. This is the model that reads the photographs. |
| Open-Meteo | Your coordinates, or a place name you typed | Recent weather, soil temperature and rainfall for your location. |
| OpenStreetMap (Nominatim) | Your coordinates | Turning coordinates into a town name, so the result says where it was about. |
| United States Department of Agriculture | Your coordinates | The soil series under your lawn. |
| phzmapi.org | Your postcode, when you give one | The plant hardiness zone. |
| Resend | Your email address, only if you asked for the follow-up | Sending the one message asking how the diagnosis turned out. |
| Supabase and Vercel | Everything stored, as the database and the hosting | Running the service. They process it for us and do not use it themselves. |
How long it is kept
Until you delete it. There is no automatic expiry, because the value of the record is that it can be checked against what the lawn turned out to have, and that can be months later. If that is not what you want, delete it: the link below does it immediately and completely.
Deleting it
Open the result you want removed and use Delete this diagnosis. It removes the photographs, the record and the usage counts together, and it cannot be undone.
Because there are no accounts, the link to a diagnosis is the only proof that it is yours. That cuts both ways, and it is worth being plain about it: nobody can delete your diagnosis without your link, and nobody, including us, can find it for you if you lose it.
On your device
No tracking cookies. The browser keeps a short list of your recent diagnoses so the app can ask how they turned out, your access code if you were given one, and a random id used only to count how the screens are used. Clearing your browser storage removes all of it, and none of it identifies you.
Children
This is a tool for people who look after a lawn. It is not intended for children and asks nothing of them.
