Health data is special category personal data under GDPR Article 9. We access Google Health Connect only on Android devices, only with your explicit permission, and only to read the signals necessary to calculate your Sleep and Vitality pillar scores within The System.
What we read: sleep duration, sleep stages, step count, and active energy expenditure. These are used to produce a numeric score (0–100) for the relevant pillar. The raw data records themselves are processed on-device and are never transmitted to or stored on SystemOS servers.
Your control: You can revoke Health Connect access at any time via Android Settings → Health Connect → App permissions → The System. Revoking access will cause affected pillar scores to fall back to manual check-in values. It will not delete your account or other data.
Google Health Connect is provided by Google LLC and governed by Google's own privacy policy. SystemOS is not responsible for Google's data practices within the Health Connect platform itself.
