Privacy Policy
Last updated: September 28, 2026
This policy explains what information Linebook (and its sister products SharpLens and Grid Ledger) collects, how it is used, and the choices you have.
Information we collect
- Account details: your email address, an optional username and profile photo, and a securely hashed password.
- Google sign-in: if you choose "Continue with Google", we receive your Google account ID, email address and whether it is verified. We do not receive your Google password or access to any other Google data.
- Content you add: bets, bankroll settings, notes, tags and bet slip screenshots you upload or send to your Telegram bot.
- Billing: subscription status from our payment provider (Whop). We never see or store your card details.
- Technical data: session cookies to keep you signed in and IP addresses used for security and rate limiting.
How we use it
- To create and secure your account, including sending verification and password reset codes by email.
- To provide the service: tracking bets, calculating results and settling bets against match data.
- To read bet slip screenshots with an AI vision provider, only to extract the bet details.
- To manage your trial and subscription.
We do not sell your personal information and we do not use it for advertising.
Service providers
We rely on trusted providers to run Linebook: Railway (hosting and database), Resend (transactional email), Google (optional sign-in), OpenAI (bet slip reading), Telegram (optional bot) and Whop (payments). They process data only as needed to provide their service to us.
Retention and deletion
We keep your data while your account is active. You can ask us to delete your account and its data at any time by emailing linebook.stats@gmail.com.
Security
Passwords and one-time codes are stored hashed, connections use HTTPS, and sign-in endpoints are rate limited. No system is perfectly secure, but we work to protect your information.
Changes
If we change this policy we will update the date above.
