Cookie Policy
Version of 20 September 2026
How we use cookies
Cookies are small files a site stores in your browser. Some are needed for the site to work; the rest are not. We set the necessary ones immediately and load nothing else until you tell us we may. If you decline, the analytics and marketing scripts are never added to the page.
Strictly necessary
Always set. No consent required.
| Cookie | Purpose | Lifetime |
|---|---|---|
sessionid | your session | up to 2 weeks |
csrftoken | protects forms against cross-site request forgery | 1 year |
tekvel_consent | remembers your cookie choice | 1 year |
tekvel_region | remembers which regional site you chose | 1 year |
django_language | interface language | 1 year |
Analytics
Loaded only after you accept.
| Service | Provider | Purpose |
|---|---|---|
| Google Analytics | Google LLC, United States | how the site is used |
| Yandex Metrica | YANDEX LLC, Russian Federation | traffic statistics, click maps, referral sources |
[TO CONFIRM] Whether Yandex Metrica should run on the international site at all. It is a transfer of visitor data to the Russian Federation, which needs a transfer mechanism and is worth a deliberate decision rather than inheriting it from the shared codebase.
Marketing
Loaded only after you accept.
| Service | Provider | Purpose |
|---|---|---|
| Facebook Pixel | Meta Platforms Inc., United States | measuring our advertising |
Embedded content
Some pages embed third-party content that may set its own cookies when you interact with it: YouTube videos (Google LLC), the Calendly scheduling widget (Calendly LLC), Mapbox maps (Mapbox Inc.) and reCAPTCHA form protection (Google LLC). reCAPTCHA is required for the download form to work and is treated as strictly necessary.
Changing your mind
You can also delete or block cookies in your browser settings. Blocking the strictly necessary ones will stop parts of the site working.
