Privacy Policy
Last Updated: May 13, 2026
Effective Date: May 13, 2026
At Kingpin (operated by Shmaplex), we take your privacy seriously. This Privacy Policy explains how we collect, use, disclose, and protect your information when you use our global marketplace platform for used fingerboard gear.
By using Kingpin, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree, please do not use our Service.
Quick Summary: We collect information you provide (account details, listings, messages) and automatically (usage data, cookies). We use this to operate the platform, process transactions, and improve our services. We share data with service providers (Stripe, hosting) and as required by law. You have rights to access, correct, and delete your data.
1. Information We Collect
1.1 Information You Provide
We collect information you voluntarily provide when you:
- Create an Account: Email, password, username, full name, profile information
- Create Listings: Item descriptions, photos, pricing, shipping information
- Make Purchases: Shipping addresses, payment information (processed by Stripe)
- Communicate: Messages to other users, support inquiries, feedback
- Seller Information: Business details, tax information, bank account details (via Stripe Connect)

1.2 Information Collected Automatically
When you use Kingpin, we automatically collect:
- Device Information: IP address, browser type, operating system, device identifiers

1.3 Information from Third Parties
We may receive information from:

1.4 Encrypted Messages
Our platform uses end-to-end encryption for user messages. We store encrypted message content but cannot access the decrypted contents. Encryption keys are derived from your PIN and stored securely.
1.5 Analytics and User-Provided Data
We use analytics tools, including Google Analytics, to understand site usage, marketplace funnels, campaign performance, and service reliability. We do not send message contents, payment credentials, age-verification documents, government IDs, or sensitive profile details as standard analytics event data.
If we enable Google Analytics user-provided data features in the future, we will only use approved first-party information where we have the required rights, notices, and consent choices. Any such use must follow our privacy controls and may use hashed or otherwise limited identifiers rather than plain personal information.
We treat Google Analytics Advertising Features, such as Google signals, remarketing audiences, advertising reporting, demographics and interests, and ads personalization, as separate privacy choices. We do not enable those features unless our disclosures, consent controls, and compliance review support the intended use. If enabled, Google and linked advertising products may use first-party cookies or identifiers together with Google advertising cookies or identifiers for approved measurement, attribution, audience, or advertising reporting purposes.
