Privacy

The car seat checker runs entirely in your browser. The age, height, and weight you enter are never sent to a server and are not stored.

SeatChecker is a static site. We do not require an account and we do not sell personal data.

We keep simple, aggregate analytics to understand what gets used: a count of which page paths are viewed, which outside websites embed our widget (their domain only), a coarse device type (desktop, mobile, or tablet), and a country, both derived at our edge from the request. We do not set cookies, do not store IP addresses, and do not use any cross-site or advertising identifiers. None of the age, height, or weight you enter is ever collected.
