Cookie policy

No cookies are currently set for analytics or advertising. What changes at launch, and how to manage your consent, is set out here.

In short: this website currently sets no cookies — neither for analytics nor for advertising. The only thing stored is a small, technically necessary entry in your browser's local storage recording whether you dismissed the notice about the other available language. It carries no identifier and is never transmitted.

What a cookie is — and what local storage is

A cookie is a small text file a website places in your browser, and which is sent back with every subsequent request. Local storage is a second, similar place to keep something — with one important difference: it is NOT sent to a server automatically. An entry in local storage stays on your device until you delete it. Legally, § 25 TDDDG treats both cases the same in principle unless the storage is strictly necessary, which is why the one case that occurs here is named explicitly below.

What this website currently stores

Language notice dismissed — a yes/no entry in local storage so the notice about the other language version does not come back after you close it. It is strictly necessary for the function you asked for (§ 25(2) no. 2 TDDDG), carries no identifier, permits no inference about you, and is not transmitted.
Nothing else. No analytics cookies, no advertising cookies, no tracking pixels, no external scripts, no external fonts. The fonts are served from this server, so not even they open a connection to a third party.

The calculators do not store your inputs — not even locally. Reload the page and the initial values are back. That is deliberate: details from a fine notice should not be left lying around in a browser.

If and when the site launches

At launch the intention is to measure reach and to fund free operation through advertising. Both would require consent: for visitors from the EU, the EEA, the United Kingdom and Switzerland, analytics and advertising cookies would only be set after your consent (art. 6(1)(a) GDPR together with § 25(1) TDDDG). Until you decide, nothing would be set and nothing personalised. Refusing would have no effect on the calculators — they run entirely on your device and need no cookies.

Cookie table: as soon as cookies are actually set, a table will appear here with the name, provider, purpose, lifetime and legal basis of each one. While nothing is set, such a table would be a claim about something that does not exist.

How to control cookies

Independently of this website you can view, delete individually or entirely, and block cookies in your browser settings at any time. You can also clear local storage there; the language notice will then reappear. If you block cookies completely, the calculators on this site work exactly as before.
