Privacy and cookies

Last updated 4 November 2026

In short

This site uses Google Analytics only if you say yes. Nothing is used for advertising, and nothing tracks you across other sites. You can change your answer at any time with Cookie settings.

Who is responsible

Chernov Consulting OÜ, registry code 16023463, Sepapaja tn 6, 15551 Tallinn, Estonia. Write to info@chernov.io about anything on this page.

Analytics, if you accept

We use Google Analytics 4, loaded through Google Tag Manager, to count visits and see which pages are read. Google Ireland Limited processes the data for us under its data processing terms.

• What is collected: pages viewed, how you arrived (for example a search or a link), browser and device type, and an approximate location (country and city). Google Analytics 4 does not log or store IP addresses for visitors in the EU.
• Cookies: _ga and _ga_*, set on this domain to tell one visit from the next. They are only set after you accept, and are deleted when you decline.
• Kept for: 14 months, then deleted by Google Analytics.
• Not used: advertising features, Google signals, remarketing, or sharing with other Google products.
• Legal basis: your consent (Article 6(1)(a) GDPR). Withdrawing it does not affect what was collected before.

If you decline, Google Tag Manager still loads, but Consent Mode keeps Google Analytics from loading or setting cookies.

What happens anyway

• Your choice is remembered in your browser's local storage (consent) for 12 months, so we don't ask on every page. It is not a cookie and is never sent to us.
• Hosting: the site is served by GitHub Pages. Like any web server, GitHub sees your IP address when it delivers the page, and may log it for security.
• Fonts: the typefaces are served from this site itself, so showing a page sends nothing to Google Fonts.
• Email: if you write to us, we use your message and address only to reply.

Your rights

You may ask to see, correct or delete personal data we hold about you, or object to its use. Write to the address above. You may also complain to a data protection authority; ours is the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon).
