Privacy Policy
Last updated: August 25, 2026
Introduction
Slugger ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our graded baseball card tracking service.
Information We Collect
- Your account name and email, if you sign in to keep a watchlist. Sign-in is handled by Clerk, our identity provider, which holds the account and any password. We never see a password.
- Information you provide directly (watchlists, preferences)
- Usage data and analytics to improve our service
- Device and browser information
How We Use Your Information
- To provide and maintain our card research service
- To send notifications you request
- To analyze market trends and improve our data
- To communicate updates about our service
Data Security
We implement appropriate security measures to protect your personal information. However, no method of transmission over the internet is 100% secure.
Third-Party Services
We may use third-party analytics tools to understand how our service is used. These services may collect information about your visit.
Your Rights
You have the right to access, correct, or delete your personal information. Contact us to exercise these rights.
Every Type of Data We Collect
The full list. If it is not on this table, we do not collect it.
| Data | Why | Who else sees it | Kept |
|---|---|---|---|
| Your account name and email | Only if you sign in, so your watchlist follows you between devices | Clerk, which handles the sign-in itself | Until you ask us to delete it |
| Watchlists and preferences you set | To keep the site useful to you | Nobody outside our own systems | Until you ask us to delete it |
| Pages viewed, referring site, approximate region, device and browser type | Aggregate traffic measurement | Cloudflare Web Analytics, which is cookieless | Aggregate only, never tied to you |
| Which outbound link was clicked, and from which page | To see which pages are useful and to attribute commission | The retailer or marketplace you land on, under its own policy | Not linked to your email or account |
| Server logs, including IP address | To run and secure the site | Our hosting provider | Short-term, per the host's retention |
No passwords, because Clerk handles sign-in and never shares one with us, and no payment details, because SluggerData sells nothing directly. We do not sell, rent, or trade any of it.
Deleting Your Data
Stopping the emails. The unsubscribe link in any email marks your subscription inactive. The emails stop right away, but the record stays in our database.
Deleting the record. Email [email protected] from the address you signed up with and we will erase it, including any account and saved list. Requests are handled by hand, so allow up to 30 days, and we will confirm once it is done.
