Privacy
Local matching. Optional analytics.
The checker processes selected camera and card attributes in your browser. CardFit does not send or store these selections, and does not ask for an account, serial number, file, photo, video or location permission. It cannot access or format your memory card.
Off until you allow it
Yandex Metrica is not loaded until you choose “Allow analytics”. A choice is stored in this tab’s session storage, not sent as a profile. “No analytics” keeps it off; choosing this after enabling analytics reloads the page to unload the tag. You can make either choice below. If storage or analytics is unavailable, the checker still works.
What optional measurement means
When allowed on a public tool page, Metrica receives a page visit and the event names selector_start, selector_complete or unknown_result. No selected models or free-text payload accompany these events. Each event is counted at most once per page in this tab. Events before consent are not replayed.
This is not anonymous-only processing: the analytics provider may receive your IP address, browser/device information and cookies. Session Replay, click maps and automatic link tracking are disabled. Our manual page-view call sends the canonical page path with an empty referrer; it does not send URL query parameters or fragments. Analytics is disabled entirely on query/fragment URLs, preview/local hosts, automated browsers and browsers requesting Do Not Track or Global Privacy Control.
Read the Yandex privacy policy and Metrica opt-out information. Disabling analytics here stops future page collection; it does not erase information already received by Yandex or existing provider cookies.
Hosting and limitations
The hosting service necessarily receives requests for pages and assets and may keep operational logs, including IP addresses. The consent choice controls optional CardFit analytics, not those hosting requests. Consent-based tool counts omit visitors who decline analytics or use blockers; they are not the total number of search visits and do not prove that every counted visitor is human.
