Datenschutzerklärung

What Bordcheck stores about you, why, for how long, and what you can do about it. Required by Art. 13 GDPR.

Last updated 3 Oct 2026

The principle this site is built on

Bordcheck asks for no sign-in, no email address and no account. You can plan your system, have it checked and export it without telling us who you are. There is no Google Analytics, no Facebook pixel, no advertising cookie and no tracking across other websites. That is also why you see no cookie banner here: we set nothing that would need your consent.

We have not appointed a data protection officer; we are not required to.

What is stored, and why

Every kind of data Bordcheck holds is in this list. Nothing beyond it is collected.

Language preference

Where it comes from
A cookie on your device, set only once you choose a language
Why it is needed
So the page opens in the language you chose, not the one guessed for you
Legal basis
Art. 6 (1) (f) — a preference you asked for
Kept for
400 days from your choice, or until you clear your browser

Visitor identifier

Where it comes from
A random number in a cookie, and the matching row in the database
Why it is needed
So this browser finds the designs it made, without an account or a password
Legal basis
Art. 6 (1) (b) — providing the service you asked for
Kept for
400 days from the visit on which it was set

Your design

Where it comes from
What you put on the canvas: components, cables, lengths and the name you gave it
Why it is needed
So it survives a reload, a new device and a link you share
Legal basis
Art. 6 (1) (b) — providing the service you asked for
Kept for
As long as the design exists

Feedback you send

Where it comes from
The message you type, and your email address only if you add one
Why it is needed
So the problem you reported can be understood and answered
Legal basis
Art. 6 (1) (f); Art. 6 (1) (a) for the email address you chose to give
Kept for
The message stays; the email address is erased after 180 days

Usage events

Where it comes from
What happened and when — no IP address, no browser, no link to you
Why it is needed
So it is visible which parts of the tool work and which do not
Legal basis
Art. 6 (1) (f) — improving the tool
Kept for
180 days

IP address

Where it comes from
The address your request arrives from
Why it is needed
So one machine cannot flood the site with requests
Legal basis
Art. 6 (1) (f) — keeping the service available
Kept for
In memory only, for one rate-limit window, then gone

Export survey answers

Where it comes from
The three questions asked when you export, if you answer them
Why it is needed
So it is known who the tool is actually being used for
Legal basis
Art. 6 (1) (a) — you chose to answer
Kept for
Kept without a time limit: the answers are joined to nothing else and cannot be traced to a person

Cookies

Exactly two cookies, both set by us, neither for statistics and neither for advertising.

loadmap_visitor ties your designs to this browser so your work is not lost — a random identifier, no name, no email address. It is httpOnly and SameSite=Lax, so scripts on the page cannot read it, and it expires 400 days after the visit on which it was set. Legal basis: § 25 (2) no. 2 TDDDG (strictly necessary for the service to work) and Art. 6 (1) (f) GDPR.

loadmap_locale remembers whether the site is shown to you in German or in English. It is written only when you choose a language yourself — make no choice and we set nothing — and then lasts 400 days. Legal basis: § 25 (2) no. 2 TDDDG, Art. 6 (1) (f) GDPR.

Your designs

When you plan a system we store the document on our server so you can open it again from another device and share it over a link. It holds what you entered — components, values, cable lengths and the names you give them. We assume nothing personal about you is in there; if you give your design your own name, your name is in there.

A design is reachable only over its link. Whoever has the link can read it. The edit link is a second secret: whoever has it can change the design. Treat both like a password.

Legal basis: Art. 6 (1) (b) GDPR — without storage there is no service. Kept for: as long as the design exists.

Usage measurement

We measure how Bordcheck is used, but without recognising you. The evaluation runs on our own server. What is recorded is what happened — a component was added, an export was opened — and when.

Not recorded: your IP address, your browser (user agent), the page you came from (referrer), the visitor cookie or any hash of it, and no identifier of your designs. Events within one visit are tied together by a random number that lives only in the memory of your browser tab and reaches neither a cookie nor localStorage.

Legal basis: Art. 6 (1) (f) GDPR. Kept for: 180 days, after which the entries are deleted.

Feedback you send

When you write to us through the feedback function we store your message and — if you tick the boxes — the design it is about and the findings Bordcheck showed for it. You may give an email address, but you do not have to. It is used only to answer you. No account, no newsletter, no list.

Not stored: your IP address, your browser and the page you came from.

Legal basis: Art. 6 (1) (f) GDPR, and for the email address Art. 6 (1) (a) GDPR — consent you may withdraw at any time. Kept for: we keep the message to improve the product; your email address is erased after 180 days.

Sending email

When you send us feedback, it reaches us as an email we send through Brevo (Sendinblue SAS, Paris, France). Brevo processes the content of the message, the attached design and, if you gave one, your email address on our behalf, under a data processing agreement pursuant to Art. 28 GDPR. Brevo may have data processed outside the European Economic Area; Standard Contractual Clauses pursuant to Art. 46 GDPR apply to that.

IP address

To prevent abuse we briefly count how many requests come from one address. That count lives in memory alone, for at most the length of one window, and is neither stored nor logged anywhere. Legal basis: Art. 6 (1) (f) GDPR.

Hosting

Bordcheck runs at Codesphere GmbH, in a data centre in Frankfurt am Main, Germany. A data processing agreement pursuant to Art. 28 GDPR is in place. No transfer to a third country takes place.

Accounts and payment

There are at present neither accounts nor payment. The full export is free and needs no sign-in.

Your rights

You have the right of access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction (Art. 18), data portability (Art. 20) and objection (Art. 21).

In practice: because Bordcheck does not know you, an email asking us about your data usually cannot be matched to a stored person — there is none. If you want a particular design deleted, send us its link.

Complaining to a supervisory authority

You may also complain to a data protection supervisory authority (Art. 77 GDPR), in particular in the country where you live or work, or where you believe something went wrong.

Changes

This statement describes the position as of the date at the top of this page. When what Bordcheck stores changes, we change it.
