A weight of zero pauses a variant without losing its history. ### Parameters passed on UTM parameters added to the short link reach the destination, without overwriting its own. ### Tags File your links by client, campaign or channel, and filter your analytics with them. ### Checked destinations Every destination is checked against Google Web Risk when saved, then regularly. A link that turns dangerous is blocked. ## What does not change ### No cookies Your visitors receive no cookie and no ad ID, and their IP address is never kept. ### Hosted in the EU The servers are in Germany, and the data is never sold. ### Built in public Klyk’s deployments are visible live on the [Behind the scenes](https://getklyk.io/en/built-with) page. ## Frequently asked ### Is Klyk free? Yes, today: everything on this page is included, no card required. An hourly creation limit keeps abuse at bay, with no monthly quota. ### Can I change where a shared link leads? Yes, at any time, and that is what the product is for. The short address never changes, what it points to does. ### Do I need to install anything? No. Klyk works in the browser, on a computer as on a phone, and your links work everywhere. ### What happens if I leave? Your links are yours. You export your analytics, and if your links are on your own domain, you redirect them wherever you like without breaking what is already printed. ## Try it on your next link. Free, no card required. The first numbers arrive with the first click. [Create a free account](https://getklyk.io/en/signup) · [About](https://getklyk.io/en/about)
