This checkout stores an anonymous entitlement key as a hash, the product and amount, PayPal order/subscription/payment identifiers, payment state, and paid-period expiry. PayPal handles payment account details; this service does not store card numbers or passwords. The checkout stores the entitlement key in this browser session to verify your purchase. Payment records support entitlement checks, refunds, and duplicate-event prevention. No browsing history is collected. Contact chatterboxapps@gmail.com for support, access, or deletion requests. Deleting active entitlement records can prevent purchase verification. Cloudflare hosts this service and may process connection and security logs under its own policies.
