A cookie is a small file a site stores in your browser. This page lists every cookie and measurement script yandef.com can set, and what each one is for.
Nothing optional loads before you agree. Analytics scripts are injected only after you press Accept analytics in the notice at the bottom of the page. If you reject them, or simply ignore the notice, they are never downloaded at all.
1. Strictly necessary
These are required for the site to work, and are not optional.
| Name | Set by | Purpose | Expires |
|---|---|---|---|
yandfsess |
yandef.com | Holds the anti-forgery token that protects the contact and newsletter forms from being submitted from another site on your behalf. | When you close your browser |
yandf_consent |
yandef.com | Remembers whether you accepted or rejected analytics, so we stop asking. Stored in your browser's local storage, not sent to our server. | Until you clear your browser data |
2. Analytics — only with your consent
| Service | Provider | Purpose | Typical lifetime |
|---|---|---|---|
Google Analytics 4 (_ga, _ga_*) |
Google Ireland Ltd. | Counts visits, tells us which pages are read and where people leave. IP addresses are anonymised. | Up to 2 years |
| Google Tag Manager | Google Ireland Ltd. | Loads the measurement tags above. Sets no cookie of its own. | - |
| Ahrefs Analytics | Ahrefs Pte. Ltd. | Cookie-free traffic measurement, used to see which pages attract visitors from search. | No cookie set |
With analytics enabled we also record a small number of interaction events - contact form viewed, contact form submitted, newsletter submitted, phone / e-mail / WhatsApp link clicked, case study opened, call-to-action clicked - so we can tell how well the site actually works. These events contain no personal data.
3. Embedded content
Our contact page embeds a Google Maps frame. Loading that page means your browser contacts Google directly and Google receives your IP address; Google may set its own cookies in that frame under its own policy. No other page on this site embeds third-party content.
4. Changing your mind
- Use the link above at any time.
- A rejection takes effect immediately for future page loads; scripts already running in the current tab stop when you reload the page.
- You can also block or delete cookies in your browser settings. The site keeps working, minus the forms' anti-forgery protection if you block all cookies.
5. More information
How we use the data these tools produce is described in our Privacy Policy.
