The short
of it.

Your account email, what you log as meals, and any continuous-glucose readings you connect from third-party devices (Dexcom, Libre, others, via Terra). Photos you take of meals are stored to render your history. If you grant HealthKit or Health Connect access, we read steps, sleep, weight and glucose locally — what we transmit to our servers is documented in our data-flow specification, available on request.

We use it to predict your glucose response to meals — that's the product. We use de-identified aggregates to improve the model. We do not sell your data. We do not run third-party advertising on it.

Engineering and support staff under access controls. Our backend providers (Firebase / Google Cloud) per their published terms. Nobody else.

For as long as your account is active. Delete your account in-app and the user record plus its associated meals, predictions, and connections are removed. CGM data forwarded to us via Terra is governed by Terra's retention terms in parallel.

Access, correction, deletion, portability. Email us at privacy@glucoserepublic.com and we'll respond within a working week.

This is the short, plain-language version of our privacy posture. The long-form, GDPR/APP-compliant version is in revision and is available on request from legal@glucoserepublic.com. When it ships publicly, the date at the top of this page will update.
