Cookie-free analytics
We also use Umami, hosted on our own server. It doesn’t set cookies or store anything on your device and doesn’t collect data that identifies you, so it doesn’t need your consent.
Amazon links
Our site doesn’t set Amazon cookies. If you click an affiliate link, Amazon.com may use its own cookies on its website to attribute the purchase, under its own cookie policy.
