ScienceHairStack collects limited usage data to improve routine quality, page clarity, and reliability. We do not sell personal data.

- Analytics events in production via Google Analytics (for example: CTA clicks, product toggles, routine submissions, FAQ interactions).
- Basic page-view and interaction metadata from Google Analytics.
- Local browser storage values (`shs:user-profile`, `shs:inventory`) so your form selections persist on your own device.
How data is used
- Measure feature usage and identify unclear flow steps.
- Evaluate whether warning patterns reduce routine conflicts.
- Prioritize content updates and trust-page improvements.
Third-party processors
Google Analytics is used as a third-party processor in production environments. Review the Google data policy for details on their processing terms.
