Notes

If the policy changes, the Company will notify you on the application at least 14 days before the material changes take effect. Continued use of the service after the effective date constitutes acceptance of the updated policy.

Chem Limiter is currently a consumption recording tool for general consumers and is not registered as a medical device with the Food and Drug Administration (FDA). Measured values are estimates for awareness purposes only, not for disease diagnosis. If Chem Limiter is registered as a medical device in the future, this policy will be updated and you will be asked for new consent before data processing begins in a medical device capacity.
