Cookie Policy
Last updated: May 18, 2026
Managing your preferences
On your first visit, Pricelyzer shows a cookie consent banner that lets you accept all cookies, reject everything except strictly-necessary cookies, or pick per-category. Your choice is stored locally in your browser under the key pricelyzer_consent for 12 months. You can change your choice at any time by clicking — or by clearing site data, which resets the choice and re-shows the banner on your next visit.
Strictly-necessary cookies cannot be disabled because the service cannot function without them (you can't sign in if the auth session cookie is blocked).
1. What are cookies
Cookies are small text files placed on your device by a website or application. They allow the site to remember your session, preferences, and interactions across page loads. Pricelyzer uses cookies and similar technologies (local storage, session storage) on pricelyzer.app and app.pricelyzer.app.
2. Strictly necessary cookies
These cookies are essential for the service to function. They cannot be disabled. No consent is required for strictly necessary cookies under GDPR (Recital 66) or CCPA (the "operational" exemption).
- Authentication session cookies. When you sign in, Pricelyzer issues an HTTP-only, Secure session cookie. The cookie name is managed by our authentication provider (Supabase Auth) and typically takes the form
sb-<project>-auth-token. We use theSameSiteattribute to mitigate cross-site request forgery. Duration: session, or up to 30 days if you select "stay signed in." pricelyzer_ui— Stores small UI preferences (e.g. dismissed banners, last-used tool). HTTP-only is not required because this cookie contains no authentication data. Duration: up to 30 days.
3. Analytics
We do not load third-party client-side analytics scripts on Pricelyzer pages (no Google Analytics, no Mixpanel, no Plausible script, no Segment). We rely on server-side aggregates — request counts, latency percentiles, error rates — tied to an anonymised session identifier. No analytics cookie is set on your browser.
You may request that your account be flagged to exclude any usage telemetry by emailing privacy@pricelyzer.appwith subject line "Opt out of analytics."
4. Affiliate attribution
Pricelyzer does not currently set or share third-party affiliate-attribution cookies. If we add affiliate networks in the future, we will update this page and our sub-processors list at least 14 days before any customer personal data is shared, and we will provide opt-out instructions for the relevant networks here.
The Pricelyzer server-side affiliate redirect (/api/affiliate/redirect) does not set any cookie on your browser. No affiliate tracking cookie is set on the pricelyzer.app domain.
5. Browser extension
The Pricelyzer Browser Extension does not set cookies on any domain. The extension uses Chrome's chrome.storage.local API to persist your last-used lookup result locally on your device. This data never leaves your browser except as part of the lookup API request described in the Privacy Policy.
6. Browser controls
All modern browsers allow you to view, delete, and block cookies. Instructions for popular browsers:
- Chrome: Settings → Privacy and security → Cookies and other site data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Safari: Preferences → Privacy → Manage Website Data
- Edge: Settings → Cookies and site permissions
Important:blocking Pricelyzer's authentication session cookie will prevent you from signing in. Strictly necessary cookies cannot be functionally disabled without preventing the service from working.
7. Changes to this policy
We may update this Cookie Policy to reflect changes in the cookies we use or applicable law. Material changes will be communicated via email or in-app notice. Continued use after the effective date constitutes acceptance of the updated policy.
