Frequently asked questions
How do the searches work?
The GrailTrakr extension runs in your own Chrome browser. Every night, or when you click Run update, it searches your Marketplaces with your own login in a background window, then saves matches to your account. Chrome needs to be open on your computer for it to run.
Which browsers does it work in?
The site works in any browser, on your phone too. The searches need the GrailTrakr extension, which runs on a desktop or laptop in Chrome and browsers built on it, such as Edge, Brave, Arc and Opera. Safari and Firefox aren't supported yet.
Where does FMV come from?
FMV comes from the price service you choose as your primary, read with your own login. GPA Analysis or GoCollect today, with more on the way. Connect a second and its value shows beside the first as a cross-check, so you can see when they disagree.
Which marketplaces does it search?
Facebook Marketplace in Canada and the US today. eBay and auction houses such as Heritage are next, and new connectors arrive with each release.
What are flagged grails?
Flag up to five grails and GrailTrakr searches them every hour while Chrome is open, from 7 AM to midnight. When a new find fits your spec, you get one alert on your phone and computer, and by email if you turn that on in Settings.
Why does Facebook say a listing no longer exists?
Check which profile the Facebook app or site is using. Marketplace only works on your personal profile, so if you are switched to a business Page, every listing shows as gone. Switch back to your own profile and the link opens.
Will it message sellers or buy for me?
No. GrailTrakr only reads listings. It never messages, offers or buys. You decide what to do with every find.
Which graders are supported?
CGC universal grades are valued today. CBCS and PGX copies are found and flagged. PSA comes next.
Is my data private?
Your grails, finds and settings belong to your account and nobody else can see them. Your marketplace and price service logins never leave your browser.
What does it cost?
Two plans. Start is $5 USD a month or $50 a year for up to 5 grails. Grow is $15 USD a month or $150 a year for unlimited grails and every connector. GrailTrakr is free and invite only during beta.
Can I share my account?
Accounts are single use only. You can connect the extension in up to two of your own browsers.
