Cookies are small text files placed on your device when you visit a website. We also use browser local storage, which works similarly but stores data locally on your device without sending it to a server. This page explains exactly what we store, why, and for how long.
We store a session token in your browser's local storage to keep you signed in between visits. This token expires after 30 days and is never shared with third parties. It contains no personal information other than a reference to your account.
We use a privacy-first analytics tool to understand general usage patterns, such as which pages are most visited, which countries visitors are from, and which device types are used. Our analytics sets no cookies, collects no personal data, and cannot identify you individually. All analytics data is self-hosted on our own server and is never shared with third parties.
This site is funded in part by advertising, and advertising is the one place where cookies from another company are involved. We ask before any of it loads.
If you accept advertising in our consent banner, we load Google AdSense. Third-party vendors, including Google, then use cookies to serve ads based on your prior visits to this website or other websites. If you decline, or have not answered the banner yet, no advertising script is loaded and no advertising cookie is set. Declining costs you nothing: every calculator and guide on this site works exactly the same either way.
You can opt out of personalised advertising through Google Ads Settings, or opt out of third-party vendors' use of cookies for personalised advertising at aboutads.info/choices. To change your answer on this site, clear your site data for tax-calculator.nl and the consent banner will appear again.
You can clear browser local storage at any time. Note that doing so will sign you out of your account.
