This Privacy Policy describes how SlabROI ("we", "us", or "our") handles data when you visit our website.
We respect your privacy. Because our calculator operates entirely within your browser using basic JavaScript, we do not collect, store, or transmit any personal data or calculator inputs to our servers. Your financial inputs and card values remain completely private on your device.
While we do not collect personal data directly, our website uses third-party affiliate networks to monetize the platform:
These third parties have their own privacy policies and data collection practices. We do not have access to the personal data or payment information you provide to eBay or Amazon.
Our website is hosted on a third-party platform (GitHub Pages) which may automatically collect standard web server logs. This typically includes non-identifiable information such as your IP address, browser type, referring pages, and timestamps. This data is used solely by the host for security and ensuring site reliability.

By using SlabROI, you agree to the following terms and conditions. If you do not agree, please do not use our tool.
SlabROI is a participant in the eBay Partner Network and the Amazon Services LLC Associates Program, affiliate advertising programs designed to provide a means for sites to earn advertising fees by linking to eBay.com and Amazon.com. When you click on links to various merchants on this site and make a purchase, this can result in this site earning a commission.
The calculations provided by SlabROI are estimates based on user-provided inputs and assumed costs. They are for informational and entertainment purposes only.
Under no circumstances shall SlabROI, its creators, or its affiliates be held liable for any direct, indirect, incidental, or consequential damages resulting from the use of, or inability to use, this calculator. This includes financial losses incurred from grading fees, shipping damages, or cards selling for less than anticipated.
We provide this tool "as is" and without any warranty or condition, express, implied, or statutory. We do not guarantee that the tool will be error-free, that the math will be updated to reflect recent grading fee changes, or that the site will always be available.
