Guidelines
Please do
- Report to security@marketsizer.io as soon as you find an issue.
- Give us reasonable time to investigate and fix before any public disclosure.
- Provide enough detail to reproduce (steps, URLs, request/response, and a proof of concept).
- Test only against your own account or data.
Please do not
- Do not access, modify, or delete data that is not yours.
- Do not run denial-of-service, spam, or social-engineering attacks against our staff or users.
- Do not use automated scanners that degrade the service for others.
- Do not publicly disclose an issue before we have confirmed it is resolved.
Our commitment
If you report in good faith and follow these guidelines, we will not pursue or support legal action against you. We will acknowledge your report, keep you updated on our progress, and - with your permission - credit you once the issue is resolved. We do not currently operate a paid bug-bounty programme.
