Privacy & Security

By joining this study, you agree to share the specified data metrics from your datastore on an anonymized basis with the study, including study investigators, and for the purposes of creating public reporting based on data contributed on an anonymized basis by all study participants.  Only data from the study time range will be accessible by the study.

All participant data will be anonymized, including location data.  Location data will only be used to group participants into large geographic areas using a spatial indexing algorithm (h3).  It will not be possible to de-anonymize or identify you based on data shared with or published by the study.

Reporting

Intermediate samples for the study (post-anonymization) are stored encrypted at rest on Nillion's SecretVault. Participation in this study is entirely voluntary, and you can leave at any time.  If you choose to leave/opt out, we will not include any of your data in any subsequent study reporting or analysis.

After final analysis, all raw samples will be deleted.
