Privacy policy

What we collect

When you sign up, we store your email, username, league memberships, bets, and balances in our database (Supabase). Authentication is handled by Supabase Auth.

How we use it

Data is used to run leagues, show leaderboards, settle bets, and keep your account secure. We do not sell your personal information.

Third parties

We use Supabase for hosting and authentication, Vercel for the website, Polymarket’s public API for odds, and Google AdSense to show advertisements. Those services have their own privacy policies.

Google may use cookies or similar technologies to serve personalized or non-personalized ads. You can learn more and manage ad settings at Google’s Ad Settings and review how Google uses data for ads.

Cookies and local storage

The app uses browser storage for session tokens and UI preferences. Advertising partners (including Google AdSense) may also set cookies or local identifiers related to ad delivery and measurement.

Where required, Google’s certified consent platform asks for your choices before advertising cookies are used. You can review or withdraw those choices at any time using “Privacy & cookie settings” in the site footer.

Support feedback

If you submit feedback or a complaint, we store the message, category, priority, and optional contact email in our database. When configured, a copy is also written to an internal support spreadsheet and emailed to our support inbox (support@stackedsports.online). We use this only to investigate and improve the product.

Your choices

You may stop using the service at any time. To delete your account and data, use “Delete my account” on the Account page. You can also contact support@stackedsports.online.
