Calculator. The numbers you enter are processed in your browser and are not sent to us.

Email alerts. If you sign up, we store your email address with our email provider and use it only to send price-change alerts and a monthly roundup. We do not sell or share it. Every email has a one-click unsubscribe link, and you can ask us to delete your address at any time via the contact page.

Outbound links. When you click to a vendor, that vendor's own privacy policy applies, and a referral link may tell the vendor you came from us.

Analytics. We may use privacy-friendly, aggregate page-view statistics.
