Privacy Policy
Last updated: August 24, 2026
This Privacy Policy explains how BidDown LLC ("BidDown," "we," "us") collects, uses, and shares information when you use the BidDown marketplace.
Information we collect
Account information from Clerk (name, email, profile image) when you sign up; listings, bids, messages, and reports you create; payment and subscription information processed by Stripe (BidDown does not store your card details); referral/affiliate attribution when you arrive via a referral link; and usage data such as pages viewed and actions taken on the platform.
How we use it
To operate the marketplace: creating your account, posting listings, matching bids, processing coin and membership purchases, sending want-match notifications, reviewing reports and flagged activity to keep the marketplace trustworthy, and maintaining marketplace security. We do not sell your personal information.
How we share your information
Other users can see information that's inherently public on the platform: your username, listings, bids, and public profile. If you signed up through a First Edition shop's referral link, that shop is notified (with your name and listing details) when you post a want listing, as part of that referral program. We share information with the service providers listed below so they can perform services on our behalf, and may disclose information when required by law or to protect BidDown's or users' rights and safety. If BidDown is involved in a merger, acquisition, or sale of assets, information may be transferred as part of that transaction.
Service providers
We rely on Clerk for authentication, Supabase for data storage, Stripe for payments, Resend for transactional email, and Vercel for hosting and analytics. Each processes data under its own privacy policy and security practices.
Cookies and analytics
BidDown uses cookies required for authentication and session management (via Clerk), plus a first-party referral/affiliate attribution cookie (30-day expiry) when you arrive via a referral or outreach link. We use Google Analytics and Vercel Analytics to understand aggregate site usage; these are not configured for cross-context behavioral advertising. We don't use third-party advertising cookies.
AI-assisted features
BidDown does not currently offer AI-powered chat or prompt features. If we introduce them, we'll update this policy to name the provider(s) used (for example, Anthropic) and describe how your inputs are processed. We'll contractually require any such provider to maintain appropriate data protection safeguards and prohibit them from using your data to train their own general-purpose AI models.
Your privacy choices
You can update your profile information at any time, and can request account deletion by contacting support. We don't sell your personal information or share it for cross-context behavioral advertising, and we don't use interest-based advertising on BidDown. Some browsers let you send a "Do Not Track" or Global Privacy Control signal; we currently don't respond to Do Not Track, but if we ever do sell or share personal information as defined by state privacy law, we'll honor Global Privacy Control as a valid opt-out. Some information (like transaction records) may be retained as required by law.
State privacy rights
If you're a resident of California, Colorado, Connecticut, Virginia, Nevada, or Indiana, state privacy law may give you additional rights over your personal information: the right to know what we've collected, the right to access a copy of it, the right to correct inaccuracies, the right to delete it, and the right to opt out of its sale or use for targeted advertising or certain profiling. BidDown doesn't sell personal information or use it for targeted advertising or profiling today, so most of these opt-out rights have nothing currently to opt out of, but you can still exercise your right to know, access, correct, or delete by contacting us below. California residents can also reach the Complaint Assistance Unit of the California Department of Consumer Affairs at 1625 N. Market Blvd. Suite N112, Sacramento, CA 95834, or (800) 952-5210. We may ask you to verify your identity (typically from the email on your BidDown account) before acting on a request, and reserve the right to decline a request where state law permits.
Data security and retention
We rely on our service providers' security practices (Clerk, Supabase, Stripe) and access controls to protect your information, though no online service can guarantee perfect security. We retain account and transaction information for as long as your account is active and as needed to comply with legal, tax, and dispute-resolution obligations after that.
Children's privacy
BidDown requires users to be at least 18 (consistent with our Terms of Service) and is not directed at anyone younger. We do not knowingly collect personal information from anyone under 18. If you believe we've collected information from a minor, contact us and we'll delete it.
Changes to this policy
We may update this policy as the product evolves. Material changes will be reflected here with an updated date.
