Responsible disclosure

Data security is a top priority for Colabra, and we believe in working with skilled security researchers to identify any weaknesses.

Security audit

If you believe you've found a security vulnerability in Colabra's service, please notify us; we will work with you to resolve the issue promptly.

Disclosure policy

Provide us a reasonable amount of time to resolve the issue before disclosing it to the public or a third party. We aim to resolve critical issues within one week of disclosure.

Make a good faith effort to avoid violating privacy, destroying data, or interrupting or degrading the Colabra service. Please only interact with domains you own or for which you have explicit permission from the account holder.
