Privacy Policy

Last updated: March 2026

Overview

CheckFirst is a free price comparison tool. We collect as little data as possible and do not sell or share your information with third parties.

What we collect

  • Product URLs and ZIP codes: submitted when you run a search. Used only to fetch price results. Search results are cached for up to 7 days to speed up repeat searches.
  • IP address: used for rate limiting to prevent abuse. Not logged or retained after the request.
  • Email address: only if you opt in to price-drop notifications. Used solely to notify you if we find a lower price. You can unsubscribe at any time by emailing info@checkfirst.shop.

We do not create accounts, track sessions, or build profiles on users.

Analytics

We use a privacy-friendly analytics tool that collects no personally identifiable information, uses no cookies, and does not track you across websites. Only aggregate counts (page views, search totals) are collected.

Cookies

CheckFirst does not use cookies. Your preferences (ZIP code, Prime status) are held only in your browser session and are never stored on our servers.

Advertising

CheckFirst plans to display ads via Google AdSense in the future. When enabled, Google AdSense may use cookies to serve personalized ads. You can opt out at Google Ads Settings. Currently, no ad network is active on this site.

Affiliate links

Some links on CheckFirst are affiliate links. We are a participant in the Amazon Services LLC Associates Program and may earn commissions from other retailers. This never affects the prices you see or how results are ranked, we sort by total cost only. Commissions come from the retailer, not from you.

Children’s privacy

CheckFirst is not directed at children under 13. We do not knowingly collect information from children under 13.

Changes to this policy

We may update this policy from time to time. The “Last updated” date above reflects the most recent revision. Continued use of CheckFirst after changes constitutes acceptance of the updated policy.
