Payment Security

PaddleGurus uses Stripe as our 3rd party processing.

Using the Stripe API, PG redirects you to Stripe when you click "Register"

The Stripe popup for payment, is as secure as any payment system on the web. Here is a link to their security info as well as their below documentation.


Security is one of the biggest considerations in everything we do. If you have any questions, or encounter any issues, please contact us at


Stripe has been audited by a PCI-certified auditor, and is certified to  PCI Service Provider Level 1. This is the most stringent level of certification available.


Stripe forces HTTPS for all services, including our public website. We regularly audit the details of our implementation: the certificates we serve, the certificate authorities we use, and the ciphers we support. We use  HSTS to ensure browsers interact with Stripe only over HTTPS. Stripe is also on the HSTS preloaded lists for both Chrome and Firefox.
For more about implementing SSL on your own website, read our  SSL guide.


All card numbers are encrypted on disk with AES-256. Decryption keys are stored on separate machines. None of Stripe's internal servers and daemons are able to obtain plaintext card numbers; instead, they can just request that cards be sent to a service provider on a static whitelist. Stripe's infrastructure for storing, decrypting, and transmitting card numbers runs in separate hosting infrastructure, and doesn't share any credentials with Stripe's primary services (API, website, etc.).


We rapidly investigate all reported security issues. If you believe you've discovered a bug in Stripe's security, please get in touch at (optionally using our PGP key at the bottom of this page). We will respond as quickly as possible to your report. We request that you not publicly disclose the issue until it has been addressed by Stripe.

Vulnerability Reward Program

We understand the hard work that goes into security research. To show our appreciation for researchers who help us keep our users safe, we operate a reward program for responsibly disclosed vulnerabilities. Stripe rewards the confidential disclosure of any design or implementation issue that could be used to compromise the confidentiality or integrity of our users' data (such as by bypassing our login process, injecting code into another user's session, or instigating action on another user's behalf). A minimum reward of $500 USD may be provided for the disclosure of qualifying bugs. At our discretion, we may increase the reward amount based on the creativity or severity of the bugs.
If you report a vulnerability that does not qualify under the above criteria, we may still provide a minimum reward of $100 USD if your report causes us to take specific action to improve Stripe's security.
As with most security reward programs, we ask that you use common sense when looking for security bugs. Vulnerabilities must be disclosed to us privately with reasonable time to respond, and avoid compromise of other users and accounts, or loss of funds, which are not your own. We do not reward denial of service, spam, or social engineering vulnerabilities. Although Stripe itself and all services offered by Stripe are eligible, vulnerabilities in third-party applications which use Stripe are not.
And finally, as with most security reward programs, we have a couple restrictions. We will only reward the first person to responsibly disclose a bug to us. Any bugs that are publicly disclosed without providing us a reasonable time to respond will not be rewarded. Whether to reward the disclosure of a bug and the amount of the reward is entirely at our discretion, and we may cancel the program at any time. Your testing must not violate any laws. We can't provide you a reward if it would be illegal for us to do so, such as to residents of countries under current U.S. sanctions (e.g. North Korea, Libya, Cuba, etc.).
Thank you for helping keep Stripe, our users, and their customers safe!
