Cookie Policy

This Cookie Policy explains how WebSpeed (operated by KO Data) uses cookies and similar technologies on webspeed.pro, the audit tool and the account area. It should be read together with our Privacy Policy.

1. What cookies are

Cookies are small text files stored on your device by your browser. Local and session storage are similar browser features that keep data on your device. They let a site remember your choices and function correctly. Everything below is first-party — stored for webspeed.pro itself — and nothing is used for advertising.

2. Strictly necessary

These keep the Service working and are set without asking.

Name	Purpose	Where	Retention
ws_lang	Remembers your chosen interface language.	Cookie	~1 year
ws_key	Remembers an audit access key so you can reopen a private report and proxy links within a session.	Cookie	~1 year (session-scoped)
kc-consent	Remembers whether you allowed or declined analytics, so we do not ask on every page.	Local storage	12 months after “Allow”, 6 months after “Decline”
ws-theme	Remembers the theme you switched the site to. Set only when you use the theme toggle or open a link that picks a theme.	Local storage	30 days
ws-currency	Remembers whether you chose to see prices in euros or US dollars. Set only when you use the currency switch.	Local storage	12 months

3. Analytics — only if you allow it

We measure how the site and the audit tool are used with KO Data’s own analytics counter. KO Data is the company that runs WebSpeed, so this is not a third-party service. The counter is not loaded at all until you choose “Allow” in the cookie banner; if you decline, none of the entries below is set.

With your consent, it records the pages you view, time on page and activity, the page you landed on and the referring address (including campaign tags), events in the audit tool (for example, that an audit started or finished, with the scores it produced), and — when you submit a form on the site — the contact details you entered, so a request can be matched to the visit it came from. The data is sent to KO Data’s servers at Hetzner in the EU.

Name	Purpose	Where	Retention
_ko_uid	Pseudonymous visitor ID, so repeat visits count as one visitor.	Cookie and local storage	5 years
_ko_visit_id	ID of the current visit, tying its page views together.	Cookie and local storage	5 years
_ko_session_id, _ko_touch_id__session	The current browser session.	Cookie	Until you close the browser
_ko_client_id, _ko_touch_id	Link your visits to a request you send us.	Cookie and local storage (ko.user.*)	5 years
ko.metrika.*	The first page and referrer of your visit, activity timers, and the last form submitted (so it is not sent twice).	Local and session storage	Until cleared / end of session
ws_ev:*, ws_run:*	Keep one event — such as “audit finished” — from being counted twice when the page reloads.	Session storage	End of session

4. Changing your choice

Use Cookie settings in the footer of any page to see the banner again and change your answer. Choosing “Decline” also deletes the analytics entries listed in section 3 from your browser. Your choice is not a condition for using the Service — everything works the same either way.

You can also control or delete cookies through your browser settings, and set most browsers to block them. Blocking strictly-necessary cookies may mean parts of the Service (like remembered language or report access) no longer work.

5. Changes

We may update this Cookie Policy as the Service evolves. The “last updated” date above reflects the current version.
