What they are
Cookies are small files that a website stores in your browser to remember something about your visit. Here we also use the word cookies for other ways of storing data in the browser, such as local storage.
The ones we always use
These are the ones essential for the website to work or to remember what you choose. They do not need your consent.

Statistics without cookies
We count visits with Umami, which does not use cookies or store data that identifies you.
The ones we only use if you accept them
There are two types: statistics, to find out how the website is used and improve it, and advertising, to measure our ads and show you Synentor ads on other websites. Until you accept them, the website does not load these tools.

Your choice
The first time, we ask you with a notice: you can accept them all, reject them all or choose. The three options are equally easy to reach and none is preselected.
You can change your mind at any time with the “Cookie settings” button in the footer. If you withdraw your consent, we delete the cookies of those tools that are on our domain and the website stops loading them; the ones those companies place on their own domain you can delete from your browser.
Your choice is valid for 12 months; after that we ask you again. We keep proof of it without your IP address, as explained in the privacy policy.
From your browser
You can also block or delete cookies from your browser:
Review
We review this policy at least once a year and whenever we change the tools on the website.
