Privacy

Health data is as personal as it gets. Here is exactly how Human Metrics treats yours — in plain language.

Effective 2 August 2026 · humanmetrics.health

What we collect

Human Metrics stores what you give it, and nothing more: your account details (name, email, and a salted hash of your password — never the password itself), your food diary, custom foods you create, health readings you log (weight, blood pressure, stress, symptoms, and any metrics you define), your daily targets, and your region preference.

We use no advertising trackers, no third-party analytics, and no fingerprinting. The only cookie is a single session cookie that keeps you signed in; it is HTTP-only and never readable by scripts.

Photo estimates

When you use a photo to estimate a dish's macros, that photo is sent to Anthropic's Claude API for analysis and the estimate is returned. Photos are not stored by Human Metrics — only the resulting estimate you choose to log is saved. Anthropic does not use API inputs to train its models; see Anthropic's privacy documentation for their retention practices. If you never use photo estimates, no image ever leaves your device.

Connected devices

If you connect a wearable such as Whoop, we store the access tokens needed to sync and the health data the sync retrieves (recovery, HRV, sleep, strain). You can disconnect at any time from Settings, which removes the tokens immediately; already-synced readings remain yours and stay in your account until you delete them. We only request read-only scopes.

Where your data lives

Your data is stored in a private database operated by Human Metrics — not on third-party analytics platforms. Access to it in transit is encrypted. Health data is only ever visible to your own signed-in account: custom foods, diary entries and readings are scoped to you and are not visible to other users.

What we never do

We do not sell your data, share it with advertisers, or use it for any purpose other than showing it back to you and computing the insights you ask for. The only third parties that ever receive anything are the ones you explicitly invoke: Anthropic when you submit a photo for estimation, and your wearable's provider when you connect it.

Your data, your call

You can delete individual entries and readings anywhere in the app. To delete your account and all associated data, or to request an export, contact privacy@humanmetrics.health and it will be actioned promptly.

Food database sources

The food database is built from public sources: Food Standards Australia New Zealand (AFCD and AUSNUT, used with attribution), the USDA FoodData Central (public domain), and Open Food Facts (© Open Food Facts contributors, licensed under the Open Database License). These sources describe foods, not you — none of your personal data is ever contributed back to them.
