Cookies and technical data

The contact form cookie

Interacting with the Russian contact form on tezra.ru creates tezra_contact, a technical cookie used to verify the session and protect against forged requests. It contains a random value, a timestamp and a cryptographic signature, not your name or message.

Lifetime

30 minutes; a new session request can renew the expiry.

Scope

tezra.ru, only requests to /api/contact.

Protection

Secure, HttpOnly and SameSite=Strict.

Purpose

Form submission and abuse prevention, without advertising tracking.

Opening the English homepage or these documents does not create this cookie. Blocking cookies may prevent form submission; you can still email info@tezra.ru.

Your choice and how it is saved

“Accept all” permits Vitaliy Mishin to enable optional anonymous blog view statistics. “Necessary only” and “Reject” disable them. Both refusal options retain the essential cookies needed for the functions you request and to remember your choice. There are no advertising trackers.

Statistics are off before you choose. You can change your choice or withdraw permission at any time using “Cookie settings” in the footer. Withdrawal stops new view submissions; previous aggregates cannot be linked to an individual visitor.

The tezra_privacy cookie stores your choice, terms version 2026-10-05.1 and choice time for 180 days. Its scope is .tezra.ru, including the main website and blog, with Secure, SameSite=Lax and Path=/. It contains no unique visitor identifier. Expiry or a new terms version prompts a fresh choice. Blocking cookies may prevent your choice from persisting across pages.

Permission for statistics does not consent to enquiry processing, which has a separate checkbox.

Optional blog statistics

Only after “Accept all”, the first-party counter on blog.tezra.ru sends the opened page path and permission version. The server increments an aggregate daily count. Statistics store no IP address, contact, choice cookie or individual browsing history. The counter uses no localStorage, fingerprinting or persistent identifiers.

Do Not Track and Global Privacy Control take precedence: views are not submitted when either is enabled, even after “Accept all”. The ?analytics=off parameter also excludes the current opening; it is not a persistent preference for subsequent pages.

Logs and external services

Network and HTTP information is transmitted when a browser connects to a server. The main website maintains technical request logs. The blog does not keep a normal visit access log, although infrastructure may record diagnostic errors. Logs differ from cookies and are not disabled by blocking cookies.

Public pages use no Yandex Metrica, Google Analytics, advertising pixels, embedded social widgets or third-party fonts. External links lead to services governed by their own rules; displaying a link does not load that service’s code.

The banner controls optional statistics. It does not switch off the server’s technical security logs.

Managing browser data

You can remove tezra.ru and blog.tezra.ru data in your browser settings or block cookies. The website does not save your name, contact or message in localStorage or sessionStorage. Your browser may retain autofill and history according to your own settings.

For cookie and data questions, contact Vitaliy Mishin at info@tezra.ru. See the privacy policy for processing purposes and your rights.
