Cookie policy
1. The short version
The website itself works without cookies. The only optional tool is Google Analytics 4, which we use to see which pages are read. It is not loaded at all until you click «Accept analytics» in the banner, and you can change your mind at any time with «Cookie settings» at the foot of every page.
2. Cookies and similar technologies
| Name | Provider | Purpose | Duration | Consent |
|---|---|---|---|---|
bca_consent_v1 (browser storage) | This website | Remembers your choice in the banner | Until you clear it | Not required — strictly necessary |
_ga, _ga_TJCKMWMHWZ | Google Ireland Ltd. (Google Analytics 4) | Distinguishing visits and counting page views, scrolls and outbound clicks | Up to 2 years | Only if you accept |
__cf_bm | Cloudflare | Telling people from bots | 30 minutes | Not required — strictly necessary |
3. Other third parties
Google Fonts sets no cookies, but your browser sends its IP address to Google when loading the typefaces. FormSubmit is involved only when you send the contact form.
4. Local calculations
The calculators work in your browser and do not store or send what you type; Google Analytics does not receive the values you enter.
5. Withdrawing consent
Click «Cookie settings» at the foot of any page and choose «Reject»: analytics stops and its cookies are deleted. You can also block cookies in your browser settings. More on personal data in the privacy policy.
