Cookie notice
One technical cookie and nothing else.
What we set
A single cookie — lang — holding your language choice (ru or en) so the site opens in your language next time. It is kept for one year.
What we do not set
There are no advertising or analytics cookies, no social-media pixels and no third-party trackers on this site. That is why you do not see a cookie banner: a strictly necessary cookie does not require consent under PECR.
How to remove it
Clear cookies for a1-is.tech in your browser settings — the site keeps working and simply detects the language from your browser again.
