Privacy & Cookies
What we collect, how we use it, and the cookies we set.
Surplus Inventory is maintained by Mantissa Technologies. This page explains what information the site collects, how it is used, and the cookies we set — including the analytics cookie governed by the consent choice you make when you first visit.
Information we collect
- Account details. When you create an account, sign-in is handled by our identity provider (Auth0). We store your email address, name, role, and subscription status to operate your account. We never see or store your password.
- Listing data. Parts you publish — including the manufacturer, part number, description, quantity, price, and the contact email and phone number you choose to display — are stored so buyers can find and contact you.
- Payment data. Subscriptions are processed by Stripe. Card details are handled by Stripe directly; we do not store them.
- Usage data. If you consent to analytics, we collect aggregate information about how the site is used (see below).
Cookies and analytics
We use Google Analytics to understand how visitors use the site so we can improve it. Google Analytics sets cookies and collects aggregate usage data such as pages viewed and approximate location.
Analytics is governed by Google Consent Mode: until you accept, no analytics cookies are set and no usage data is collected. When you first visit, a banner lets you Accept or Decline. Your choice is remembered in your browser so you are only asked once. To change it, clear your browser's site data for Surplus Inventory and the banner will appear again.
We also use a Cloudflare Turnstile check on listing pages to keep scrapers and spammers from harvesting sellers' contact details. This is a security measure, not advertising tracking.
How we share information
We do not sell your personal information. We share data only with the service providers that make the site work — our identity provider (Auth0), payment processor (Stripe), email provider (Resend), analytics provider (Google), bot protection (Cloudflare), and our hosting and database infrastructure. Contact details on a listing are shown publicly by design, after a bot check, so buyers can reach you.
Your choices
You can decline analytics at any time using the consent banner as described above. For questions about your data, or to request access to or deletion of your account information, reach out through our Contact Us page.
