Privacy Policy

BioSignal Health builds a public knowledge platform, not an advertising product. Our default is to collect the minimum needed to run the site well and improve it — nothing more.

• No sale of personal data. We do not sell, rent, or trade personal information.
• No behavioral ad targeting. BioSignal does not serve ads or build advertising profiles.
• Minimal by default. We prefer aggregate, privacy-preserving measurement over anything that identifies an individual.

When you visit BioSignal, we collect limited, privacy-preserving usage analytics — such as which pages are viewed and general performance metrics — to understand what is useful and to keep the site fast. This measurement is aggregate and is not used to identify you personally.

We store a small amount of information in your browser to make the site work — for example, your light or dark theme preference. This stays on your device and is not a tracking identifier. If you send feedback through the site, we receive the message you choose to share so we can act on it.

We do not require an account to read BioSignal, and we do not ask for health information about you. Please do not send us personal medical details through feedback or email — BioSignal is educational and cannot provide individual medical advice (see our Medical Disclaimer).

You can browse without providing personal information. Most browsers let you clear local site data and block or limit analytics at any time. If you have a question about your data or a request regarding it, contact us at hello@biosignal.health.

As BioSignal grows, this policy may be updated to reflect new features or legal requirements. Material changes will be noted here with a revised “last updated” date. This page is a plain-language summary of our practices and does not yet constitute legal advice; it should be reviewed by qualified counsel before public launch.
