Vulnerability Disclosure Policy

Last Updated February 28, 2022

At TaxBit, Inc., we take security of our users' data very seriously. If you've discovered, or believe you've discovered, potential security vulnerabilities in the TaxBit product, we encourage you to disclose your discovery to us as quickly as possible in accordance with this Responsible Disclosure Program.

We'll work with you to validate and respond to security vulnerabilities that you report to us. Because public disclosure of a security vulnerability could put the entire TaxBit community at risk, we require you to keep such potential vulnerabilities confidential until we are able to address them. We won't take legal action against you or suspend or terminate your access to any TaxBit services, provided you discover and report security vulnerabilities in accordance with this Responsible Disclosure Program. TaxBit reserves all of its legal rights in the event of any noncompliance.

Capitalized terms that aren't defined in this Responsible Disclosure Program shall have the meaning set forth in our Terms of Service.
