Built for the research rabbit hole
See a park.
Keep the idea.
From an official team guide to a ticket listing or travel article, the companion turns browsing into a cleaner ballpark short list.

Mark the park as visited with a date, or add it to the places you want to chase next.

A discreet page button and the extension popup bring you back to Ballpark Passport whenever you want the full guide.
Privacy, without the fine-print fog
Your browsing history is not the product.
The companion has no analytics, no ads, no account requirement, and no permission to read every site all the time. It checks only the active page after you open it and stores your ballpark list locally in Chrome.
- Active tab only No background browsing surveillance.
- Local storage Your saved parks stay in this browser.
- No data sale Nothing is collected or sent to us.

Chrome visit and wish-list statuses do not yet sync to the iPhone app. That connection will arrive only after there is a secure sign-in and extension-safe API. Until then, the companion is deliberately simple and honest about where your data lives.
Every ballpark. One tab away.
