In short

Everything you enter (salary, tax class, canton …) is calculated in your browser and never sent to us. We use no cookies, no tracking or analytics tools and no advertising, and we load no third-party content such as web fonts.

Hosting

The site is delivered by Cloudflare Pages (Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA). When you visit, Cloudflare processes technically necessary connection data (e.g. IP address, time, requested page, browser type) to deliver the site securely and fend off attacks. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in secure and stable operation). A data processing agreement is in place; Cloudflare is certified under the EU-US Data Privacy Framework. On the home page only, the country Cloudflare derives from your IP address and your browser’s language setting are used to forward you to the matching calculator; nothing is stored and no cookie is set.

Contact by email

If you email us, we process your address and message only to answer you (Art. 6(1)(f) GDPR) and delete them once no longer needed. Mail to [email protected] is forwarded to our mailbox via Cloudflare Email Routing.

Partner links

Under “Next steps” we link to third-party offers. Links marked “Ad” are partner (affiliate) links: if you sign up through them we may receive a commission. We do not pass on anything you enter. Only when you click such a link does the provider or affiliate network process data about the click on its own website (e.g. with cookies) to attribute the referral; its own privacy policy applies.

Local storage

If you choose the light or dark theme, or click a result (year, month or hour) to highlight it, these settings are saved in your browser’s local storage. They never leave your device and can be deleted at any time in your browser settings.

Your rights

You have the right of access, rectification, erasure, restriction, data portability and objection (Art. 15–21 GDPR), and the right to lodge a complaint with a supervisory authority.
