Privacy Policy
Last updated June 22, 2026
This Privacy Policy describes how MainMarket, Inc. (“MainMarket,” “we,” “us”) collects, uses, and shares information when you use MainMarket Sports (the “Service”). We keep this short and plain because the Service is simple: you give us an email and the teams you care about, and we send you sports updates.
Information we collect
- Your email address: to create your account and send the updates you ask for.
- Your follows: the teams and leagues you choose, so we can personalize what we send.
- Email engagement: whether emails are opened and which links are clicked, so we can improve what we send and report aggregate performance to advertisers.
- Usage and device data: basic analytics such as pages viewed, approximate location, browser, and device, collected when you visit our site.
We do not ask for, or store, payment information; the Service is free.
How we use it
- To send and personalize the emails you subscribe to.
- To operate, maintain, and improve the Service.
- To measure engagement and support advertising that keeps the Service free.
- To protect against fraud, abuse, and security issues, and to comply with the law.
How we share it
We do not sell your personal information. We share data only with service providers who help us run the Service, under contract and only as needed, for example our email delivery provider (Resend), our database and authentication provider (Supabase), and analytics tools. We may share aggregated, de-identified metrics (such as overall open and click rates) with advertisers. We may also disclose information if required by law.
Cookies and tracking
We use cookies and similar technologies for analytics and to keep you signed in. Our emails may include a tracking pixel and link redirects to measure opens and clicks; you can limit this in most email clients, and turning on Apple Mail Privacy Protection (or similar) reduces what we can see.
Your choices
- Unsubscribe any time, in one click, from any email, or manage which emails you get in your account.
- Access or delete your data by emailing us; we’ll honor verified requests as required by law.
- Update your follows at any time from your account.
Data retention and security
We keep your information for as long as your account is active or as needed to provide the Service, then delete or de-identify it. We use reasonable technical and organizational measures to protect your data, though no method of transmission or storage is completely secure.
Children
The Service is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we’ll delete it.
Changes to this policy
We may update this Privacy Policy from time to time. If we make material changes, we’ll update the date above and, where appropriate, notify you by email.
