GridReady privacy notice

GridReady is an early-stage project run by Jan Rosetzky, ahead of incorporation. This notice explains what a screening records and why, in plain terms. Questions or removal requests go to privacy@gridready.eu.

Notice version 1.0, last updated 26 July 2026.

What we use your data for

We process the data behind a screening for three purposes: to run the screening you asked for, to build an honest benchmark of Dutch battery readiness over time, and to operate and secure the service. We do not use it for anything else.

What a screening records

When you screen a site we store the address you entered, the coordinates it resolves to, the municipality and grid operator, the technical inputs you gave (power, storage, direction), the role you picked if you gave one, and the full readiness result. We keep this to build an honest benchmark of Dutch battery readiness over time. The benchmark is how the score gets better.

A screening that fails is recorded too. If we cannot resolve the address you typed, or the screening breaks on our side, we store the address as you entered it together with the reason it failed. Knowing which addresses we cannot read is how we fix the gaps, and hiding those attempts would leave the benchmark flattering itself.

We also count how the portal page itself is used. We record that the page was opened, and a few in-page actions, such as which example site you opened, which tab you switched to, which button you pressed, and whether a deep dossier finished. If the page hits a script error we record the error message. Each of these carries the same per-visit id as a screening and nothing more. It is our own counting, on our own server, with no cookies and no third party involved, and we delete it after twelve months. The other pages on this portal, including this one, run no script and record nothing. Our public landing page sits on a separate site and does two things worth naming: it carries a small block of descriptive markup that search engines read, and it remembers your light or dark preference in your own browser, in the same way this portal does. It counts nothing, sets no cookie, and sends nothing about you anywhere.

On what legal basis

Storing a screening record and using it to measure the benchmark rests on our legitimate interest in improving the service, weighed against your right to privacy. The record carries no name, no IP address and no browser details, and it is kept only as long as it is useful. Until the scrub described below runs, it does hold the address you typed and the exact coordinates, so we treat the whole record as personal data throughout. Where you choose to leave contact details with feedback, that rests on your consent, which you can withdraw at any time.

What we never store

We never store your name, your IP address, your browser details, or any tracking cookie on the public portal. We never store who owns the land. The only identifier attached to a screening is a short per-visit id that lets us count visits without knowing who you are. The one exception is the feedback form: if you tick the box and leave an email address, we store that address, and only then.

Who can see it

The service runs on a small set of servers operated by a European hosting provider, named on this page once one is chosen for public testing. Nobody else receives your data: GridReady runs no third-party analytics and no advertising trackers, and shares nothing with a data broker. If error monitoring is switched on we will only use a monitor hosted in the European Union, configured not to send personal data. No name, contact detail, IP address, browser detail or cookie is attached to a report. It does receive the text of the error itself, and an error caused by an address we could not read can carry that address in its text. A public screening is never sent to an AI model provider: the score itself is computed by fixed rules on our own server, not by a model, so no model provider ever sees your address or your inputs.

Automated decisions

The score is worked out automatically, by a fixed, versioned set of rules, not by a person reviewing your case. It is decision support, not a legal or financial decision about you: it carries no automatic consequence, and we do not use it for profiling. Read our how it works page for what the score does and does not claim.

How long we keep it

After twelve months we scrub the detail from older screenings. The exact address is deleted, the coordinates are truncated to the kilometre square they sit in, and the full dossier is removed. What is left is the benchmark signal, which includes the municipality and grid operator, that kilometre square, the technical inputs, the role and any declarations you gave, the per-visit id, and the scores. That is what the benchmark needs, and it no longer points at a single address.

What we store in your browser

The public portal sets no cookies. It keeps two small values in your browser's own storage, never sent anywhere but back to us: your colour mode preference (light or dark), under the key gr-mode, kept until you clear it or change browsers; and an anonymous, randomly generated per-visit id, under the key gr-vid, which exists only for that browser tab and disappears the moment you close it. Neither value can be used on its own to identify you.

Feedback and contact

If you leave feedback it is anonymous, unless you tick the box to share your email and ask us to get in touch. We store an email only when you have ticked that box. That email is the one thing we hold that identifies you directly. We keep it until you ask us to delete it, or until the public test ends, whichever comes first. The twelve-month scrub above does not reach it, so if you want it gone sooner, email us and we will remove it.

Where it runs

The service runs on servers in the European Union.

Your rights

Giving us this data is voluntary: you can use the service without a screening being stored only by not running one, and nothing about using the site is conditional on it. You have the right of access to what we hold about you, rectification of anything inaccurate, erasure, a restriction on how we use it, a right of objection to our use of it, and a right to portability, a copy in a machine-readable format. To use any of these rights, or to ask a question, email privacy@gridready.eu. If you are not satisfied with our answer, you can also lodge a complaint with the Autoriteit Persoonsgegevens, the Dutch data protection authority.
