We use a payment service called Adyen for all the payments and for storing the payment details. Adyen is a trusted service used by many global companies such as Spotify and Uber.
The payment details are always encrypted, and the ResQ servers have only access to the basic card identifying information (name of the cardholder, expiry date, and the last 4 digits of the card).
If you’re interested in reading more about Adyen and their security certificates, you can find additional information here: https://www.adyen.com/legal
