Bug Bounty Program

We take the privacy and security of our clients seriously and are always interested in finding security vulnerabilities so that we can address and fix them. If you find a bug, we encourage you to submit your findings, which may be rewarded as part of a bug bounty.

Your contribution not only protects our users but also makes you an important partner in the continuous improvement of our security standards.

The following test methods are not permitted, among others:
