Third Party Services

Third-Party Services

This plugin communicates with the following third-party services:

Nostr Relays (CLINK Protocol)

• Purpose: Request and receive Lightning invoices from the merchant's CLINK-compatible wallet.
• When: At checkout, when a customer places an order using the CLINK payment method.
• Data sent: Merchant's noffer offer data, payment amount in satoshis, order description, and ephemeral public keys.
• Relay URL: Determined by the merchant's noffer string (configured in the gateway settings).
• Privacy note: No personal customer data (name, email, address) is transmitted to Nostr relays. Only the payment amount and a short order description are shared. Customers choosing wallet-based auto-renewal (ndebit) authorize the merchant to pull future subscription payments; the ndebit string and subscription amount are known to the Nostr relay.

CoinGecko

• Purpose: Fetch the current BTC-to-fiat exchange rate for price display.
• When: On checkout page load, every 5 minutes (result cached in WordPress transients).
• Data sent: The store's currency code (e.g., usd, eur).
• Privacy policy: https://www.coingecko.com/en/privacy
• Note: If configured, a fixed exchange rate in the plugin settings bypasses this service entirely.

ShockWallet.app

• Purpose: Informational links for customers to generate CLINK noffer/ndebit strings.
• When: When the customer clicks the link (no data sent by the plugin automatically).
• Privacy policy: https://docs.shock.network/privacy
