How Millibar Nitrox is built
- HTTPS only. The site is served exclusively over HTTPS; plain HTTP requests are redirected.
- No accounts. There is no sign-up, login or password, so there are no credentials to steal.
- Calculations stay in your browser. Everything you type into the calculator is processed on your device and is not sent to our servers or stored by us.
- No stored personal data. We keep no database of users. The only data involved are short-lived hosting logs and, if you accept, Google Analytics, as described in the privacy policy.
Reporting a vulnerability
If you believe you have found a security issue, please email hello@millibar.io with a description, the steps to reproduce it and the affected URL. We will acknowledge your report and keep you updated while we fix it.
Please give us reasonable time to fix the issue before disclosing it, and do not access other people's data or disrupt the service while testing. Our contact details are also published in security.txt.
