Privacy policy

Last updated 2026-10-19

This page explains what Combat Sports Network ("CSN", "we") collects when you use https://csnfights.com, why, and the choices you have.

What you can use without an account

You can read every page without signing in. Picks, your profile name and settings you make while signed out are stored only in your browser (local storage). They never leave your device unless you sign in.

Accounts

If you sign in with Google or an e-mail link, our account provider (Supabase) stores your e-mail address and, for Google sign-in, your name and profile picture. We store your picks, XP, leaderboard name, favourite fighter and division, your watchlist and the leagues you join. Your leaderboard name, XP, record and picks are visible to other users on leaderboards and in leagues. Your e-mail address is never shown publicly.

If you subscribe, we store your e-mail address to send fight-week e-mails. Every e-mail has an unsubscribe link, or you can ask us to delete your address at the contact address on the site.

AI analyst

When you ask for an AI breakdown, the request (the fight, the model's numbers and your question) is sent to Anthropic's API to generate the answer. We record how many requests each account makes per day to enforce limits. We do not send your e-mail address to Anthropic.

Payments

CSN Pro payments are handled by Stripe. We never see or store your card details. Stripe tells us that a payment succeeded so we can switch Pro on for your account.

Analytics

We use Cloudflare Web Analytics, which counts page views without cookies and without tracking you across sites. Our hosting provider (Cloudflare) keeps standard server logs for security.

Cookies and storage

We don't use advertising or tracking cookies. Signing in stores a session token in your browser's local storage. The site also stores your settings and offline copies of pages so it loads fast.

Your choices

You can sign out at any time from your profile. To delete your account and everything linked to it, or to get a copy of your data, contact the contact address on the site. We delete account data within 30 days of a request.

Children

CSN is meant for adults. Accounts are for people aged 18 and over.

Changes

If this policy changes, we'll update the date at the top of this page.
