Privacy

This site keeps very little about you, and it is worth saying exactly what.

One thing here comes from somewhere else

Every font, script and image on this site is served from its own server, with a single exception: Microsoft Clarity, which measures how the site is used and is described below. There is no advertising network and no social widget, and nothing here is sold or handed over for marketing.

The four things that are kept

1. An access log, 14 days

Like almost every web server, this one records each request: the address it came from, the moment, what was asked for, whether it succeeded, and which browser asked. It is what makes it possible to see an attack, find a fault, or block whoever is hammering the site. It is deleted after fourteen days.

2. A usage record, without your address

Separately, the application keeps a record of what was looked at: which racquet or string page, in which language, and which country the visit came from. Your address is never written to it. It is converted into a code using a secret key held only by this server, mixed with the date, so that two visits on the same day can be told apart without anyone — including us — being able to work out whose they were, or connect them to the day before.

The country is worked out on this server, from a copy of a public database stored here. Your address is not sent anywhere to look it up.

These records are deleted after thirty days. What outlives them is a daily count — how many people, from which countries, which racquets they opened, which buy links were followed — which contains no code, no address, and nothing that points at a person.

3. One cookie, for your saved setups

When you save a racquet setup to compare later, it is stored in a cookie named racquetStylerSetups that lasts a year. It holds what you chose: a racquet, strings, tension, lead tape, colours, and which two of your saved setups you were comparing. It exists so your work survives closing the tab.

It is written by the page in your browser, and your browser sends it with each request, as it does with any cookie. The server reads exactly one field of it — which racquet you had open — so that the page arrives already showing that racquet instead of a blank one that fills in a moment later. It reads nothing else in the cookie and records none of it: the request log described above holds paths and counts, never this. Deleting the cookie in your browser loses your saved setups and nothing else. The only other cookies are Clarity's two, described next, and nothing here is used to follow you to other sites.

4. Microsoft Clarity, to see how the site is used

A script from Microsoft Clarity runs on each page and records how the page was used: what was clicked, how far it was scrolled, where the pointer went. That is replayed as a session and added up into heatmaps. It exists to answer the one question the records above cannot — whether the racquet configurator is actually understandable to someone seeing it for the first time — and it is read as patterns across visits, not as individuals.

It sets two cookies, _clck and _clsk, which hold the pages of one visit together and recognise a browser that comes back. Because the script is Microsoft's, Microsoft receives what it collects and handles it under its own privacy statement rather than this page — the only place on this site where that is the case.

Worth keeping in proportion: there is no account here, nothing to log in to and nothing to pay for, so none of this is attached to a name, an email or a payment. If you would rather it did not run, any tracker-blocking extension stops it and the rest of the site behaves exactly the same.

Buy links

Links to shops pass through this site first, so that we can count how often they are followed — which racquet, which shop, and nothing about who followed it. You are then sent straight to the shop, and what happens there is covered by that shop's own privacy policy, not this one.

Some of these links may earn a commission. Where they do, they are marked, and a note appears beside them.

Why we are allowed to keep any of it

Under the LGPD, the logs rest on legitimate interest (Art. 7, IX): running a site securely and knowing whether it is useful. The cookie exists to provide a feature you asked for by using it. Clarity rests on the same legitimate interest: knowing whether the site works for the people using it. Nothing here is used for advertising or profiling, and nothing is sold.

Your rights, and an honest limit

The LGPD gives you the right to know what is held about you, to correct it, to have it deleted, and to know who it has been shared with (Microsoft, through Clarity, and nobody else). To ask, write to [contact address].

There is a limit worth being straight about. Because the usage record holds no address, we genuinely cannot find your entries in it — there is nothing to match you against, which is the point of building it that way. The access log does hold addresses for its fourteen days, and that we can search if you tell us the address and roughly when.

Changes

If what is kept changes, this page changes with it, and the date below moves.
