Privacy Policy

Fairline is operated by Fairline LLC, a Connecticut limited liability company. For anything in this policy, contact legal@fairline.io.

• Account details. Email address, name, and profile picture, provided through our sign-in provider (Clerk), including via Google sign-in if you use it. We never see your password.
• Things you save. Bets you log, units and notes on them, your sportsbook and notification preferences, and your theme setting.
• Technical data. Server logs (IP address, request paths, timestamps) kept for security and debugging, error reports when something breaks, and aggregate, cookieless page analytics from Cloudflare.
• Email events. If you opt into notifications: delivery and bounce events from our email provider, so we can stop sending to dead addresses.

We do not collect payment information (there is nothing to pay for today), precise location, or contacts, and the service is not directed to anyone under 18.

To run the product: authenticate you, show your bet log and its performance, send the notifications you asked for, answer support requests, keep the service secure, and understand aggregate usage. That is the whole list. No advertising, no profiling, no sale or rental of personal data to anyone.

Fairline sets only what sign-in requires: session cookies from Clerk that keep you logged in. Your theme preference is stored with your account profile, not in a tracking cookie. Our page analytics (Cloudflare Web Analytics) are cookieless. There are no third-party advertising or cross-site tracking cookies.

Fairline runs on a small set of infrastructure providers that process data on our behalf:

• Clerk (authentication and account management)
• Railway (application hosting and database)
• Cloudflare (DNS, network security, cookieless analytics, spam protection on the contact form, and encrypted database backups)
• Resend (transactional and notification email)
• Sentry (error reporting)

Each receives only what its job requires. Beyond these processors, we disclose personal data only if required by law or to protect the service, and, if Fairline LLC is ever acquired or merged, to the successor under this same policy.

If you connect Fairline to an AI assistant (for example, Claude via our MCP connector), the assistant retrieves data from your account on your instruction: slates, odds, your bet log. What that assistant's provider does with data it receives is governed by its own privacy policy, not this one. We receive from the connection only what is needed to authenticate it and serve its requests, and you can revoke its access at any time from the assistant's settings.

Account data and your bet log are kept while your account exists. Encrypted database backups are kept on a rolling window and age out automatically. Server and error logs are kept on short provider-default windows. To delete your account and its data, email legal@fairline.io or support@fairline.io from your account address; we will delete personal data within 30 days, except what we must keep for legal or security reasons.

You can request a copy of your data, correction, or deletion at any time via legal@fairline.io. We honor these requests for all users regardless of jurisdiction. Depending on where you live (including under Connecticut's Data Privacy Act), you may have additional statutory rights; nothing in this policy limits them.

All traffic is encrypted in transit (TLS). Database backups are encrypted at rest. Access to production systems is limited to Fairline LLC. No system is perfectly secure; if a breach affects your personal data, we will notify you as the law requires.

If this policy changes materially, we will announce it on the site or by email and update the effective date above. Questions, requests, and complaints: legal@fairline.io.
