Cookies and technical data
Essential storage and optional services, explained.
01. Essential storage
PHPSESSID is a session cookie used for secure session and form functions; its lifetime depends on the session and browser settings. A form security token is stored in the server session. The emg_privacy_receipt cookie holds a random preference identifier for 180 days, with HttpOnly and SameSite=Lax and, on HTTPS, Secure.
The emg_privacy_v1 LocalStorage key holds optional categories, consent revision, choice time and random confirmation number. The site honours it for at most 180 days. These values do not contain a name, phone number, message or health information and are not used for advertising profiling.
02. Optional services
Yandex Metrica counter 61682980 runs only after analytics consent. It may set _ym_uid, _ym_d, _ym_isad and other provider-controlled values to distinguish visits and produce statistics. Provider cookie lifetimes vary; permission on this site lasts at most 180 days. Session Replay, click maps and link tracking are disabled; form contents are not added to counter parameters. Google Analytics is not loaded.
Google Maps and externally embedded videos are paused until the external-media category is allowed. Providers may then receive an IP address, browser and device information and their own cookies. Locally hosted videos do not require an external player. Following an external link opens another service, whose own rules apply.
03. Managing your choice
Use “Privacy settings” in the footer to select analytics and external media independently, or choose “Essential only”. Both optional switches are off initially. “Allow all” expresses consent for both categories under the separate technical-data consent. Closing the dialog or scrolling is not consent.
On withdrawal, the site stops analytics, clears accessible _ym_* cookies and reloads without analytics. External embeds are unloaded. The site cannot clear cookies on another domain. Browser settings provide additional controls. If LocalStorage is blocked, the preference may be requested again. If server confirmation fails, optional services remain disabled.
04. Confirmation and contact
The minimal preference log records a random receipt, a hash of a random identifier, consent revision, categories and time. These records are kept for up to three years for evidence and rights protection, not marketing. Questions: mail@evotech-mg.com. See the personal data policy for rights and request handling.
