Cookie Policy
Last updated: April 17, 2026
This Cookie Policy explains what cookies and similar technologies Dealyzer uses on our web application at app.dealyzer.ai and marketing site at dealyzer.ai, and why. It should be read together with our Privacy Policy.
What are cookies?
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work, to make them work more efficiently, and to provide information to the website owner. Similar technologies (such as local storage) serve related purposes; we refer to all of these collectively as "cookies" in this policy.
Cookies we use
Essential cookies
We use a small number of cookies that are strictly necessary for the Service to function. You cannot opt out of these without losing access to the app.
- Supabase authentication cookies. When you log in, our authentication provider (Supabase) sets cookies that identify your session. These are required to keep you logged in between page loads. They expire when your session ends or when you log out.
- Local storage (browser-side). The Dealyzer Chrome extension uses your browser's built-in storage to remember your saved position for the overlay panel and to keep a local copy of recently viewed deals. This data stays in your browser and is not transmitted to us unless you are signed in and have enabled sync.
Cookies we do not use
As of this writing, we do not use analytics cookies, advertising cookies, or social media tracking pixels on our site. If we add any of these in the future, we will update this policy and, where required by law, seek your consent first.
Third-party cookies
Some cookies are set by third parties that power parts of the Service:
- Supabase (authentication) — see Supabase's privacy policy.
- Vercel (hosting) — may set cookies for traffic routing and security. See Vercel's privacy policy.
- Stripe (when payments go live) — may set cookies on checkout pages for fraud prevention. See Stripe's privacy policy.
How to control cookies
Most browsers let you refuse or delete cookies through their settings. Instructions for the major browsers:
Blocking essential cookies will prevent you from logging in to the Service.
