Google Health Coach (Gemini) CAIHL draft report

Google Health Coach (Gemini): CAIHL reassessment

September 8, 2026. Published AI-assisted draft.

Google Health Coach describes adjustable goals, optional research participation, and controls for disabling the coach and deleting conversations. Enabling it grants broad account-data access. Disconnecting a feature and deleting information already used in conversations are separate actions.

Scope and agency posture

Consumer Google Health Coach in the Google Health app, powered by Gemini and requiring Premium. This is separate from the Gemini apps.

Posture: Mixed, patient-chosen but ecosystem-gated.

Axis: 66/100, retained provisionally. No numerical recalibration was performed.

Sources and documented findings

• Google's current product page says users can set goals and adjust plans through conversation. It describes fitness, sleep and health guidance, including integrated medical records, and says the service is not intended for medical use. https://healthapp.google/google-health-coach/

• Google's help page says enabling Coach gives it access to all health and activity data in the account. Revoking a feature or deleting a data category does not automatically remove information from conversation history. Those conversations must be deleted separately. https://support.google.com/googlehealth/answer/17055092

• The help page documents turning Coach off, removing Today insights, deleting individual or all conversations, and optional research consent. Human review is described for submitted feedback or research participation. Location permission can be withdrawn in device settings. These are documented controls, not independently tested behavior. https://support.google.com/googlehealth/answer/17055092

Patient authority

Inference from the documented workflow: Users choose goals and can adjust plans or disable the coach. Broad account access limits selective permission once enabled. No current evidence establishes a compulsory treatment or adherence path.

Critical capacity

Editorial assessment: Conversation and record context can help users prepare questions and interpret trends. Public pages do not establish consistent source citations for individual suggestions or correction of underlying medical records.

Informed control

Editorial assessment: The help page explains data categories and deletion limits unusually specifically. Feature revocation and conversation deletion are separate actions. Optional research and feedback review should not be described as default training or unrestricted human review.

Assessment and limits

The existing Mixed placement is supportable. Patient chosen guidance and goal adjustment coexist with broad data access and a proprietary ecosystem. Subscription cost alone is not an agency penalty.

Confidence: Moderate for documented controls and positioning. No account or coach interaction was tested..

Remaining uncertainty: Actual recommendation provenance, correction behavior, and the usability of separate deletion controls remain unverified.

Published documentation is evidence of stated conditions, not proof of actual implementation. Unknowns did not receive automatic negative points. Funding, sponsorship, and public code do not determine agency by themselves.

Review provenance

• Reviewer/model: OpenAI Codex / GPT-6.
• Method: Focused public-source reassessment using CAIHL: patient authority, critical capacity, and informed control. Existing evidence plus one focused primary-source pass and at most one targeted follow-up. No live product testing. Numerical scores remain provisional editorial placements, not a new calculation.
• Human review: Hugo Campos authorized publication of these AI-assisted draft reassessments on September 8, 2026. This does not claim comprehensive human verification of every finding.
• Earlier review: 2026-06-10. Historical assessment. Earlier claims are not automatically reverified by this publication.
