Slabvio ("we," "us," "our") is a sports card portfolio tracking tool. It helps collectors record their inventory, estimate market value, and get automated Hold/Consider/Sell guidance based on the numbers they enter. Slabvio does not buy, sell, hold, authenticate, insure, or take custody of any physical cards, and it is not a marketplace, broker, dealer, or grading service.
Estimated values, comp data, Sell Zone recommendations, and any other figures shown in Slabvio are informational estimates only, generated from third-party market data (including eBay listings and sold-comp services) that can be incomplete, delayed, or inaccurate. Nothing in Slabvio is financial, investment, or trading advice, and we are not responsible for the outcome of any decision you make to buy, hold, or sell a card.
You need an account to use Slabvio. You're responsible for keeping your login credentials secure and for all activity under your account. Provide accurate information when you sign up, and let us know if you believe your account has been compromised.
Slabvio is offered on a monthly subscription with a 14-day free trial. If you don't cancel before your trial ends, your subscription automatically continues and you're billed the then-current monthly price through our payment processor, Stripe. You can view current pricing on our Pricing page.
Slabvio is provided "as is," without warranties of any kind. To the maximum extent permitted by law, we are not liable for indirect, incidental, or consequential damages arising from your use of the service, including losses related to card values, missed sale windows, or inaccurate market data.
We may update these terms as Slabvio evolves. We'll update the "Last updated" date above when we do. Continued use of Slabvio after a change means you accept the updated terms.
To operate your account, calculate your portfolio stats and Sell Zone guidance, process your subscription billing, and — only if you've opted in — send you product updates.
Slabvio relies on a small number of third-party services to operate, each of which processes a limited slice of data on our behalf:
We keep your account data for as long as your account is active. If you'd like your account and data deleted, contact us using the info below and we'll take care of it.
Slabvio uses a session cookie to keep you logged in. We don't use third-party advertising or tracking cookies.
Slabvio isn't directed at children, and we don't knowingly collect information from anyone under 13.
We may update this policy as Slabvio evolves. We'll update the "Last updated" date above when we do.
Every new subscription starts with a 14-day free trial. If you cancel before the trial ends, you won't be charged anything.
You can cancel anytime from inside Slabvio (Manage Billing in your account menu), which opens Stripe's secure billing portal. Cancelling stops future billing — you'll keep full access through the end of your current paid period.
Because Slabvio bills monthly with no long-term contract, we generally don't offer refunds for partial billing periods. If you believe you were charged in error, contact us — we review these on a case-by-case basis and want to make it right.
