We use the Stripe platform to securely process payments. No credit card or other payment information is retained on localendar.com servers.
All submissions of payment info initiated at localendar.com are made via a secure HTTPS connection. The payment pop-up box is created by Stripe dynamically in an embedded iframe: you are not entering any credit card information into localendar.com but directly into Stripe over a secure connection.
Stripe has been audited to conform to the highest level of certification (PCI Service Provider Level 1) by the The Payment Card Industry (PCI).
