Experiment Data Sharing

Updated February 26, 2026

Experiment Data Sharing lets you opt in to send anonymized experiment snapshots that help improve aggregate supplement science.

Turn sharing on

Open App Preferences, then select Experiment Data Sharing.

Turn on Share anonymized experiment data.

When sharing is enabled, the page will show connection and sync details.

Check sharing status

Use the Experiment Data Sharing screen to confirm connection status, last sync time, and queued uploads.

If queued uploads are greater than zero, the app is waiting to send pending snapshots when network conditions allow.

Preview what is shared

Select Preview shared data to inspect the payload shape before upload.

This view is intended to make shared fields transparent before they are sent.

Turn sharing off and reset anonymous ID

Select Stop sharing and reset anonymous ID to disable future uploads and create a new anonymous sharing identity.

After reset, any future participation uses the new anonymous ID.

What is included and excluded

Included data can contain anonymized experiment structure, outcomes, dose and check-in timing quality, and Apple Health trend context used for experiment interpretation.

Excluded data includes direct identifiers such as name, email, profile photo, and exact birth date.

If sync looks stuck

If connection is offline or queued uploads do not clear, reopen the app and verify network status first.

If the issue persists, continue with Troubleshooting and review Privacy and Data.
