Memberful Security.

Measures we take to protect you and your customers.

We take security seriously. This document outlines the measures we take to protect you and your customers when you use Memberful.

We don't store credit card data.

We don't store credit card data on our servers. All payment processing is handled by Stripe, a certified Level 1 PCI Service Provider (the most stringent level of certification available). When credit card data is submitted via Memberful it is sent directly to Stripe via JavaScript over a secure SSL connection. The payment data never touches our servers. We use Stripe's latest technology to support SCA and 3D Secure 2.0.

We use SSL everywhere.

We force HTTPS on our website and across our application. This creates a secure connection between client and server and protects all the data transmitted over the connection.

We host in a secure environment.

Memberful runs on AWS (Amazon Web Services) via Heroku. AWS utilizes state-of-the art electronic surveillance and multi-factor access control systems. Data centers are staffed 24x7 by trained security guards, and access is authorized strictly on a least privileged basis. Multiple geographic regions allow them to remain resilient in the face of most failure modes, including natural disasters or system failures.

We keep geo-redundant offsite backups.

We take twice daily offsite geo-redundant backups of all critical application data with an enterprise level backup provider. These backups are securely hosted on hardware RAID arrays that provide RAID-6 protection.

Responsible disclosure

We rapidly investigate all reported security issues. If you've discovered a security bug, please send an email to We will try to respond within 24 hours (usually faster). We request that you not publicly disclose the issue until we can address it.
