Eir — Personal Health Sync

A single-user personal integration with the Oura API.

This is not a product. It is one person's private script that reads their own Oura Ring data into their own health records. There are no other users, no sign-up, no service, and nothing to install.

What it does

The owner of this application wears an Oura Ring and is tracking a metabolic condition with an endocrinologist. Clinical lab panels arrive a few times a year; the ring produces data nightly. This integration bridges that gap.

It reads the owner's own sleep, heart-rate variability, resting heart rate, readiness, activity, and self-authored tags, and records them alongside the owner's lab results so trends are visible between blood draws.

Who can use it

One person: the account owner. The application is not distributed, not published to any app store, not offered as a service, and cannot be connected to by anyone else. It runs locally on a personal computer.

Data handling

Data is read only from the owner's own Oura account, with the owner's consent.
It is stored locally on the owner's personal machine and nowhere else.
It is never sold, shared, redistributed, or transmitted to any third party.
It is never used to train, fine-tune, or evaluate any machine-learning model.
Credentials are encrypted at rest.

Not medical advice

Nothing produced by this integration is a medical device, a diagnosis, or medical advice. Clinical decisions belong to the owner's physicians.
