Glean is a soft journal for your gut. To do its quiet work it holds some sensitive information about you — so we want to be exact about what we keep, why, and the control you have over it. No dark patterns, no fine print that says the opposite of the headline.
The short version: your entries are yours. We don't sell them, we don't show ads, you can export or delete everything — including your whole account — from inside the app, and the one outside service that ever sees your logs (Anthropic's Claude) does not train on them.
Health information and genetic (DNA) results are special-category data under UK and EU data-protection law — the most protected kind. We collect and use them only with your explicit consent, which you give by choosing to log this information and connect your health app, and which you can withdraw at any time by removing a permission, deleting the data, or deleting your account. We use it for one purpose only: to show you patterns in your own body.
We keep the list of companies that ever touch your data short, and each is bound by a data-processing agreement to handle it only on our instructions:
Some of these process data outside the UK/EU (for example, in the United States) under appropriate safeguards such as Standard Contractual Clauses.
Everything Glean surfaces — every pattern, every gentle suggestion — is built only from your own entries. We process your logs to find rhythms across food, sleep and how you feel, and to show those back to you with their confidence in plain sight. Our lawful basis is your consent for the sensitive data, and our legitimate interest in running the account you asked for. That processing serves you, and no one else.
The microphone is used only while you are recording a voice log, and the camera only while you are photographing a meal. Neither is ever accessed in the background. You can revoke either permission in your phone's settings at any time, and the rest of Glean keeps working.
Your data is encrypted in transit and at rest, and access is limited to the systems needed to run the app. We keep what you've logged for as long as your account exists. When you delete your account — from You → Delete account — we remove your account and everything tied to it.
Wherever you live, and in particular under UK/EU GDPR, you can:
Glean isn't intended for anyone under 16, and we don't knowingly collect data from children.
Glean is not a medical device and what it surfaces is not medical advice. It exists to help you notice patterns and have a better conversation in the doctor's office — not to diagnose, treat, or replace professional care.
