Legal notice and privacy

The pages that are opened. The site counts them with Vercel Web Analytics. That tool sets no cookie and stores no identifier that would follow you between visits or between sites; it computes a session identifier server-side from a technical fingerprint renewed daily. What is measured: which pages are opened, from which country, with which kind of browser — never who opens them. A page address may contain the observation place you chose; those parameters are removed in your browser before anything is sent, so the measurement receives the page and never the place. Legal basis: legitimate interest (art. 6(1)(f)) — knowing whether the site is read, and which of its pages are.

Your IP address. Like every site, this one receives it with each request; without it the answer would not know where to go. On our side it serves one purpose: capping the number of calls one visitor can trigger on the widened search and on the cloud forecast, so that a loop or a script cannot take the site down for everyone. It is written to no database and to no file: it is held in memory, in a table where the count attached to it is forgotten after a minute, which is capped at two thousand addresses and emptied when that cap is passed, and it disappears when the server restarts. It also appears in the host's technical logs, for the period the host applies, over which we have no control and which we do not use. Legal basis: legitimate interest (art. 6(1)(f)) — the security and availability of the service.

What you type into the search box. Nothing, unless you ask for it: thirty-four thousand towns ship with the site, and your search is answered from your own device first, with no request at all. That list stops at towns of fifteen thousand inhabitants; if yours is not in it, an “Étendre la recherche” button offers to ask Open-Meteo, and it is that button — never the site of its own accord — that sends the text you typed. It goes as it stands, without your IP address and without any identifier, and nothing of it is kept by us. Legal basis: performance of the service you request by pressing (art. 6(1)(b)).

It never fires on its own. Until you press it, nothing asks for your location and your browser asks you nothing. If you do press it, it is your browser that asks for permission, and you can withdraw it at any time in its settings.

Your coordinates are sent to our server, and it has to be put that way: that is how a point on the globe gets an elevation, a time zone and a cloud forecast. Its name does not leave: it is found in the list of towns that ships with the site, on your own device. The coordinates are handled for the length of the request and written to no database and to no file. We link them to nothing: the site assigns you no identifier, so it cannot know that two positions came from the same person.

They are rounded before they leave, and that is a deliberate choice. A total eclipse turns on a few kilometres: between the edge of the path and four kilometres further in, there are twenty seconds of totality on one side and none on the other. Which is why the calculation itself runs entirely on your device, at your exact position. What travels to our server is deliberately coarser: about a hundred metres for the elevation and the time zone, about a kilometre for the clouds — which the weather model works out on an eleven-kilometre grid in any case. The page address carries that same hundred metres. A point picked by hand on the globe, or found by search, is handled in exactly the same way.

The point is then kept in your browser and written into the page address, so that you can reload it or share it. That address appears in the host's technical logs like any other; it is however removed from the audience measurement, as said above.

Legal basis: your consent (art. 6(1)(a)), given through the browser's permission prompt.

None of this is a cookie: nothing below travels with your requests, and nothing here is readable by another site. In local storage:

• the last observation place, and the six most recent ones — the first is what reopens the site where you left it, and it goes back to our routes whenever an answer is needed that we do not already have: a cloud forecast in the fortnight before an eclipse, or the name and time zone of a place that was missing them;
• whether times are shown local or universal;
• whether cloud cover is drawn;
• the rendering quality tier — the one you chose, or the one your device turned out to manage;
• the fact that you have already declined an offer to change language.

And in the site's caches, which are what let it work offline: the pages, the fonts, the images, and a small number of responses from our own routes kept for twenty-four hours. Their index is held in a local browser database.

And one reading rather than a writing — article 82 covers both, which is why it belongs here. On first paint the page asks your device what it can do: how many cores, how much memory, whether it is in data-saving mode, and the name of its graphics chip. That is what allows a choice between three rendering qualities instead of serving everybody an animation half the devices cannot hold. None of it leaves the device and none of it is sent anywhere: only the resulting tier is remembered, and that is the one in the list above.

All of it remembers either choices you made or what is needed for the site to open without a network — that is, to deliver the service you asked for. On that basis the whole of it falls under the consent exemption of article 82 of the French Data Protection Act, which is why you are shown no banner — exemption from consent not being exemption from information, hence this section. Clearing the site's data in your browser settings erases all of it, immediately and for good.

Cookies: there are none. Neither ours nor anybody else's.

One data provider only, Open-Meteo, in Germany and therefore in the European Union. It answers the questions the site cannot settle on its own: a point's elevation, its time zone, the cloud cover expected there, and the widened search when you ask for it. It is never called by your browser — our server asks it. It receives neither your IP address, nor your browser, nor any identifier whatsoever. It cannot know how many people are behind the requests it receives, nor link those requests to one another.

And one provider fewer. Naming a place used to go through an Australian service; it has been removed, and the list of towns that replaces it ships with the site. No coordinate leaves your device to be given a name any more, and there is no transfer outside the European Union left in this arrangement.

Our processor. Vercel hosts the site and provides the audience measurement. It is the only recipient that processes an IP address, as a processor and under the data processing addendum Vercel incorporates into its terms. The application's server functions run in the Paris region; transfers to the United States entailed by running the service rely on the EU—US Data Privacy Framework and on standard contractual clauses.

For how long. IP address, rate limiting: in memory only. IP address in the logs, and audience measurement: the periods set by Vercel. What is on your device: until you erase it.

And one period better named than left to be guessed at. The responses from our routes are cached at the host, in a cache shared by every visitor, and the key to such a cache is the address requested — which contains the coordinate, or the text you typed into the search box. That is what stops a question somebody else has already asked from going back out to a provider, and it is also the longest retention in the whole arrangement: eight days for a widened search, a week for elevation and time zone, a day for cloud cover. None of those entries carries an identifier or your IP address: they are questions and their answers, not visitors. A page address containing a place also appears in the host's logs like any other address.

The data controller is CROOZY, the site's publisher — full identity below. You have rights of access, rectification, erasure, restriction and portability. Write to contact@croozy.fr.

Right to object. Two of the processing operations described here — the audience measurement and the rate limiting — rest on our legitimate interest. You may object to them at any time, on grounds relating to your particular situation, by writing to the same address.

An honest note on what those rights can yield here: the site assigns you no identifier and keeps nothing that designates you. We are therefore unable to find “your” data in order to send it to you or delete it, because there is none to find — the situation article 11 of the GDPR provides for. What concerns you is on your device, and you alone can erase it, in one operation.

No automated decision-making and no profiling take place. If an answer does not satisfy you, you may lodge a complaint with the French supervisory authority, the CNIL.

Next Eclipse computes the local circumstances of each eclipse itself, from Besselian elements published by NASA's Goddard Space Flight Center, whose publications are in the public domain. The towns come from GeoNames and the coastlines from Natural Earth; elevation, time zone and cloud cover come from Open-Meteo. The first two are under the CC BY 4.0 licence or in the public domain, and the same attribution appears in the site's settings. Everything else — the code, the text, the illustrations and the animation — is the publisher's own work.

The times and conditions shown are the result of a computation and are given for information; known deviations from reality are documented in the project's repository. Observing the Sun is the observer's own responsibility: this site describes what happens in the sky, it gives no eye-protection instructions and does not replace the guidance of health authorities and astronomical societies.
