Privacy

This site stores nothing about you. No account, no database, no cookies, no tracking, no third parties. What you enter is in the address of this page — and nowhere else.

What you enter

Body height, inseam and frame measurements are in the query part of the address. They are worked out on the server and forgotten with the answer: there is no database and no session they could be written to. To keep your entries, save a bookmark — the link is the storage, and it is yours.

If you download your entries as a file (radhaltung.json), the file ends up with you and nowhere else. When you open it again, it goes to the server once, is read, turned into an address and discarded right away — it is not stored. The file contains only your entries, in plain text; pass it on the way you would pass on a link.

Light or dark

If you switch to the dark theme in the sidebar, your browser remembers this in its local storage (localStorage) — a single word, "dunkel". It never leaves your browser and is neither read nor received by the server. Switch back and it is deleted. Without this choice nothing is stored.

What the server logs

Every page request on the internet leaves a trace on the server. Here it is deliberately trimmed: the query part of the address is removed before writing (your body measurements would otherwise be in it), the referrer likewise, the user agent is never written at all, and of the IP address only the network remains, not the connection. What is left is enough to spot an attack and not enough to recognise you.

The legal basis is the legitimate interest in secure and trouble-free operation (Art. 6(1)(f) GDPR). The entries are overwritten after a short time.

If you write to me

There is a form on the feedback page. What you write there is forwarded to me by email and not kept afterwards: there is no database for it to go into, and it is not written to the access log. If you give an email address, I use it for the reply alone.

What happens to the mail after that depends on my mailbox — it sits there until I delete it. The legal basis is your wish to write to me (Art. 6(1)(b) and (f) GDPR). So that the form is not buried by programs, the server counts per network range how many messages arrived in the last hour; that count lives in memory and is gone at the next restart.

Preview image of shared links

When you share a link to your result, messengers and forums show a picture of your riding position with it. The server draws that picture when the messenger asks for it, from the measurements in the address. It then stays in memory for a short while so it does not have to be drawn again and again, and is gone at the next restart. It is not written to disk, and as everywhere, the query part of the address is not in the access log. Whoever gets the link sees your measurements in the address and in the picture, so only share it where you are happy to show them.

Cookies and third parties

None. This site sets no cookie, embeds no font, script or image from a foreign address, and measures nothing. The 3D view loads its files from the same server. That is also why there is no consent banner here: there would be nothing to consent to.

Two places lead outside, and both only on a click: the links to the manufacturers' geometry tables and — if configured — the donation button. Both are set so that your browser does not send the address of this page along; otherwise your measurements would end up in someone else's log. What happens there is governed by their privacy policy.

Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and objection, and you may lodge a complaint with a data protection authority. An access request will get a short answer, though: apart from the trimmed log lines there is nothing that could be attributed to a person.
