Privacy Policy

What We Collect

Usage analytics (everyone). We use Google Analytics 4 to understand which pages get traffic and which affiliate links get clicked — page views, session duration, approximate location (city/country level, derived from IP), device and browser type, and events like clicking through to a retailer or opening a price alert form. This data is not tied to your name or email unless you separately give us one (see below).

Email address (only if you opt in). If you use the bell icon on a product page to set a price alert, we store the email address you enter, the product and target price you asked to be notified about, and add that email to our mailing list (via our email provider, Resend) so we can send you the alert. You can unsubscribe at any time using the link included in every alert email, or by emailing us (see Contact below).

If you use the “report an issue” tool on a listing or product page to flag a wrong price or bad data, the email field there is optional — we only use it if we need to follow up on your report.

What We Don't Do

• We don't run display or programmatic ads on the site.
• We don't use ad-retargeting or cross-site ad-tracking networks.
• We don't sell, rent, or share your data with data brokers.
• We don't share your price-alert email with Amazon, Best Buy, or Newegg — it only exists in our own alert system and mailing list.

Cookies & Similar Technology

Google Analytics 4 sets its own cookies in your browser to distinguish sessions and return visits. If you submit the price alert form, Cloudflare Turnstile (our bot filter) may set a short-lived cookie to verify the submission is human. Neither is used for advertising.

When you click an outbound product link to Amazon, Best Buy, or Newegg, that retailer sets its own affiliate-tracking cookie so we can be credited for the referral if you buy something — that cookie belongs to the retailer and is governed by their privacy policy, not ours.

To opt out of Google Analytics tracking, you can install the Google Analytics Opt-out Browser Add-on or enable “Do Not Track” / block third-party cookies in your browser settings — the site works the same either way, since analytics is not required for any core feature.

Data Retention

Analytics data follows Google Analytics 4's standard event-retention settings — see Google's documentation for current defaults, since Google can change them.

Price alert emails are kept until the alert triggers, you unsubscribe, or you ask us to delete them. Issue reports are kept as long as needed to investigate and correct the underlying data.

Requesting Deletion

To stop receiving price alerts, use the unsubscribe link in any alert email. To request that we delete your email address and any associated alerts entirely, email [email protected] and we'll remove it from our alert system and mailing list.

Children's Privacy

BuyPerUnit is a general-audience price-comparison tool and is not directed at children. We don't knowingly collect personal information from anyone under 13.

Changes to This Policy

If what we collect or how we use it changes materially, we'll update this page and the “Last updated” date above.
