Two layers. Only one is your health record.

Controller

Meridian, livewithmeridian.com. Contact: hello@livewithmeridian.com. Jurisdiction follows the host of the public website. Health-diary content is not stored by that host in this version.

1. Core health vault

Diary, notes, experiments, Pattern Card answers kept after you open the companion, and on-device chat live in an encrypted vault in this browser (IndexedDB, AES-GCM). Optional PIN wraps the key. Idle lock runs when a PIN is set. Clearing site data or Wipe deletes this device’s vault. Meridian does not keep a copy.

Typed companion answers are generated on this device. Voice is offered only if the browser exposes on-device speech recognition. Otherwise the microphone stays off.

A backup file is yours. No PIN: the file contains the key. With a PIN: the file is only as strong as that PIN.

2. Website technical infrastructure

Visiting the marketing site or loading the PWA shell is not the same as uploading a menopause diary. Ordinary web hosting still sees request metadata.

The public host or CDN may process, for security and uptime: IP address; browser / user-agent; date and time; requested URL and referrer if sent; TLS and error logs.

Purpose: operate TLS, stop abuse, debug outages. Not used to build a health profile. Retention: the host’s access-log default (typically days to a few weeks). Processor: the VPS or CDN operator on your hosting invoice. We do not sell this data. The companion does not load a marketing analytics SDK.

3. Optional future Advanced AI

Off today. If it ships, only fields you tick leave the device. Diary, notes, name, and consultation pack stay. Emergencies are not sent to a model.

4. Wearables / Signals

Planned local processing through a native HealthKit / Health Connect shell. Daily derived fields would stay in the vault. No Meridian sensor cloud in this design.

5. Work pilots

A future employer pilot receives anonymised cohort counts, not identifiable series.

6. Rights

Access and deletion of health content is on your device (export, Wipe, clear site data). For website-log questions write hello@livewithmeridian.com.
