Cookie policy
Last updated: 11 October 2026
What a cookie is
A cookie is a small file that a website stores in your browser to remember information between pages or between visits.
Alongside cookies there are other ways of storing data in the browser — local storage (localStorage) and session storage (sessionStorage). This policy applies to all of them.
Strictly necessary cookies
No consent is required, because the site does not work without them.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| csrftoken | cookie | protects forms against fraudulent submissions | 1 year |
| sessionid | cookie | keeps staff signed in to the administration panel; not set for visitors | 2 weeks |
| messages | cookie | shows notices inside the administration panel; not set for visitors | until the browser is closed |
| cookie-soglasie | local storage | remembers your choice in the cookie notice | until you clear browser data |
| izbrannoe | local storage | stores the properties you mark as favourites; never sent to our server | until you clear browser data |
Analytics cookies: only with your consent
These tell us how many people visit the site, which pages they read, and whether they contact us through the form, WhatsApp, phone or email. We use this to improve the site.
They are not installed until you accept them. Until you make a choice, the site loads no analytics tool and sends no data to third parties.
We use two tools.
Google Analytics 4, provided by Google Ireland Ltd. / Google LLC.
| Name | Purpose | Duration |
|---|---|---|
| _ga | distinguishes visitors | 2 years |
| _ga_<identifier> | keeps the state of the visit | 2 years |
We have turned off Google signals and ad personalisation, and denied storage for advertising purposes. According to Google, Google Analytics does not log or store the IP addresses of visitors from the European Union.
Yandex Metrica. Under Yandex's terms of use, for sites subject to the GDPR the service is provided by Air Smart Advertising Solutions FZ-LLC.
| Name | Purpose | Duration |
|---|---|---|
| _ym_uid | distinguishes visitors | 1 year |
| _ym_d | stores the date of the first visit | 1 year |
| _ym_isad | detects ad blockers | 20 hours |
| other cookies starting with _ym_ | technical operation of the counter | from the length of the visit to 1 year, depending on the cookie |
| entries starting with _ym in browser storage | technical operation of the counter | Yandex does not state a duration |
Session recording (Webvisor) is turned off.
Yandex may also set cookies on its own domains (for example yandexuid or i). Our site has no access to them; you can delete them in your browser.
The full list of cookies for each tool is in its provider's documentation: support.google.com/analytics/answer/11397207 (Google) and yandex.ru/support/metrica/general/cookie-usage.html (Yandex).
Advertising cookies
We do not use advertising or behavioural advertising cookies. Should that change, we would update this policy and ask for your prior consent.
Who receives the data
Analytics data is processed by Google and Yandex on our behalf, under their data processing agreements. Google may process data in the United States; that transfer relies on the EU–US Data Privacy Framework adequacy decision. Yandex Metrica is governed by Yandex's terms of use. Details are in our Privacy Policy.
Third-party cookies from embedded services
When you scroll to the map on a property page, your browser connects to OpenStreetMap Foundation servers, which may log your IP address under their own policy. The map does not load if you never reach it.
Accepting, rejecting or withdrawing consent
On your first visit, the cookie notice lets you accept, reject or configure analytics cookies. Rejecting is as easy as accepting.
You can change your decision at any time through the "Cookie settings" link at the foot of every page. If you withdraw consent you had given, the site deletes the _ga, _ga_… and _ym_… cookies and the Yandex Metrica entries in browser storage, and reloads the page. From then on no analytics tool is loaded.
You can also delete or block cookies in your browser:
- Chrome: Settings → Privacy and security → Cookies
- Firefox: Settings → Privacy & Security
- Safari: Settings → Privacy
- Edge: Settings → Cookies and site permissions
Blocking strictly necessary cookies may prevent the site from working properly.
