What we do with your email
Last updated 22 August 2026
We keep your address and the city you asked for, so we can email you once — when that city goes live. That is the whole purpose. We don’t sell it, share it, or send you anything else.
What we collect
The request form collects two things: your email address and the city you requested. It asks for no name, account, password or profile.
We don’t run advertising trackers, and there is nothing on this site that follows you to other sites. We do count visits, with a cookie, and we do record a replayable version of the visit itself — what that means is set out below, in full.
One more thing, only when you actually send a request: we store a scrambled, one-way version of your IP address for a couple of hours. It is what stops a script filling the register with addresses nobody typed. It is kept apart from your request, so it says nothing about which city you asked for, and it cannot be turned back into an address by us or by anyone who obtained it.
What we use it for
- To email you when the city you asked for is indexed and live on crudo.guide.
- To count how many people asked for each city, which is what decides the order we work in. The register on the front page shows those counts. It never shows who asked — only how many.
We won’t use your address for a newsletter, marketing, or anything you didn’t ask for. If we ever want to, we’ll ask you first.
Who can see it
Not the website. The addresses live in a table that the public site has no permission to read at all — the page can add a request and read the per-city counts, and that is the entire extent of what it can do. Your address is not reachable from anyone’s browser, including yours.
Behind that, the people running CRUDO can read the list through the database’s admin console in order to actually send the emails. Nobody else.
Where it’s kept
In a Postgres database hosted by Supabase, in the EU (Frankfurt). Requests are stored with the address, the city and a timestamp.
How long we keep it
Until we’ve emailed you about your city, or until you ask us to remove it — whichever comes first. If a city turns out to be one we’ll never cover, we delete the requests for it rather than sit on the addresses.
Getting it deleted
Ask, and we’ll delete it. No form, no conditions, no “are you sure”. Message @crudo.guide on Instagram or @crudoguide on X, or reply to any email we’ve sent you. You can also ask us for a copy of what we hold about you, which will be a short list.
Other companies this site talks to
Loading a page fetches things from a few services. They see your IP address the way any website’s asset host does. None of them are given your email address.
| Netlify | Hosts and serves the site. Keeps ordinary server logs. |
| Supabase | The database the form writes to and the register reads from. |
| PostHog | Counts visits, records them, and notes which cities get asked for, on their EU servers. See below. |
| Google Fonts | Serves the typefaces the pages are set in. |
| unpkg | Serves the drawing library the globe on the front page is built from. |
| OpenFreeMap | Serves the map on the guides — only those pages, and only once a map is drawn. |
Counting visits
We use PostHog, hosted in the EU, to see how many people reach this page and how many of them get as far as asking for a city. It records the pages you open, what you click, and the usual things a browser tells any website — rough location from your IP, screen size, referrer. When a request goes through, it also records which city it was for. That is the number the register is built on.
It also records that you started filling in the form and, if you left without sending it, whether each box had something in it and how long you were there. That is how we find out where the form is losing people. It is told whether the boxes were filled, never what you filled them with.
It keeps a replayable recording of the visit for 30 days: the page as it was drawn, where the pointer went, what was clicked and in what order. We watch those to see where people get stuck instead of guessing. Two things are deliberately kept out of it — what you type into the two boxes, which is masked in your browser before any of it is sent, and the suggestion list, which would otherwise repeat the city back as ordinary text on the page. So a recording shows a box being filled in, never what went into it.
It is never told your email address, and we never ask it to build a profile of you. It sets a cookie so a second visit isn’t counted as a stranger. If you’d rather not be counted or recorded, use a browser set to Do Not Track or a content blocker; nothing on the page stops working when you do.
The guides
Six guides are public: the Warsaw, Kraków, Wrocław, Poznań and Gdańsk city guides, and the Poland country guide that shows all five cities in one index. There is no form on any of them, no account and nothing to sign into. They ask the database for nothing: every restaurant, badge and source link is already in the page when it arrives.
A saved list is encoded in the address bar so it can be copied and shared. Share-safe filters and the open venue can travel with that link too. Search text and map position stay only in the open tab.
Two things on a guide reach outside. The map is drawn from tiles served by OpenFreeMap, fetched as you pan and zoom; they receive your IP address and can infer the rough area shown by the requested tiles. Near me asks your browser for location permission. If you agree, the coordinates are used inside the page to position the map and sort places by distance; CRUDO does not explicitly send them to PostHog or to its own server.
Counting and replay work on the guides as described above. Form inputs are masked. As a defensive safeguard, search and camera parameters are removed from current, initial and session-entry URL and referrer properties before analytics are sent.
Map credit
The map is served by OpenFreeMap, and the data drawn in it is © OpenStreetMap contributors, used under the Open Database Licence. The streets, the place names and the shape of the city are theirs; CRUDO only puts restaurants on top of them.
Changes
If this changes, we’ll change this page and move the date at the top. There’s no version of this where the answer becomes “we sold your address”.
