Hangry Privacy Policy
Last updated: September 2026
Consumer health data we collect
Hangry is an iMessage-based nutrition coach. To coach you, we collect:
- Phone number (your identifier with us). If you subscribe, our payment processor collects your email and payment details.
- Self-reported body data: weight, height, age, sex, goals
- Meal logs you send via text, photo, or voice
- Wearable data from devices you connect (Whoop, Oura, Fitbit, Withings, Apple Health): recovery, strain, sleep, heart rate, activity, weight
- Conversation history with the Hangry agent
How we use it
We use your data solely to: (a) generate personalized coaching messages, (b) compute calorie and protein targets, (c) detect adherence patterns, (d) detect when to back off or push, (e) measure and improve the product (for example, whether coaching gets used and whether people subscribe). We do not sell your data, do not use it to train third-party models, and do not share with advertisers.
Third parties that process your data
- Sendblue (iMessage delivery)
- Supabase (database)
- Vercel (hosting + cron)
- Google (Gemini AI for message generation and meal extraction)
- Stripe (payments)
- Your connected wearable providers (only when you authorize them)
- PostHog (product analytics: in-app events are keyed to an internal ID, never your phone number or message content; on our website it uses a cookie, your IP address and approximate location, and session recordings with form inputs masked)
Each is bound by their own privacy commitments. Wearable authorization tokens are encrypted at rest with AES-256.
Our website
When you visit hangry.chat we use PostHog to measure visits and clicks. It sets a first-party cookie, receives your IP address (used for approximate location), and may record your session with form inputs masked. We don't collect your phone number on the website, and we don't use advertising pixels.
