Cookie policy

The site's own code sets no cookies. It saves your theme and measurement system in your browser's local storage, which stays on your device.

Yandex Metrica, our analytics tool, sets cookies on this site and keeps some data in your browser's local storage. The main cookies:

• _ym_uid and _ym_d identify a returning browser and remember the date of its first visit, for one year.
• _ym_isad notes whether an ad blocker is on, for 20 hours.
• _ym_visorc_* lets Session Replay work, for 30 minutes.
• yandexuid, yuidss, i, ymex and usst identify the browser and keep its ID in step across Yandex domains, for one year.
• gdpr, is_gdpr and is_gdpr_b note whether the visitor falls under the GDPR, for up to two years.
• yabs-sid holds a session ID until you close the browser.

Yandex keeps the full list. You can stop Yandex Metrica with its opt-out add-on for Chrome and Firefox.

Ads from Google AdSense may use cookies and similar technologies, for example to limit how often you see an ad or, with your consent, to show ads based on your interests. In the UK, the European Economic Area and Switzerland, these are used only after you agree in the consent message.

The consent platform also stores your choice, so it does not ask again on every page. For the current list of Google's cookies and what they do, see how Google uses cookies.

You can review or change your consent at any time with the "Privacy choices" link in the footer of every page. You can also block or delete cookies in your browser settings; the converters keep working without them.
