Privacy Policy

Last updated: August 16, 2026

HeyCoach is operated by MassivelyParallelSystems LLC ("we", "us"). HeyCoach is a nutrition-coaching service delivered through WhatsApp. This policy explains what we collect and how we use it, in plain language.

What we collect

Your WhatsApp phone number and profile name — this is how your account is identified. We never see your WhatsApp password or your other chats.
What you send the coach: messages, food photos, voice notes, and documents you choose to share (such as lab results), plus the profile details you provide during setup (age, height, weight, activity, goals).
Derived coaching data: your meal log, calorie/macro estimates, weight entries, the coach's notes about your preferences and goals, and daily summaries.
Payment data: subscriptions are processed by Stripe. We never see or store your card number.

How we use it

Solely to provide the service: estimating your meals, tracking your progress, and personalizing the coaching. Photos, voice notes and documents are processed by AI providers (Google Gemini for analysis, Cloudflare Workers AI for voice transcription) as data processors on our behalf. Messages are delivered through the WhatsApp Business Platform (Meta). We do not sell your data, and we do not use it for advertising.

Health information

If you share lab results or health goals, we store them to tailor your nutrition coaching. HeyCoach is not a medical service, does not diagnose or treat anything, and is not a substitute for professional medical advice. Share only what you are comfortable sharing — the coach works fine without it.

Where your data lives

Your data is stored in your own isolated record on Cloudflare's infrastructure, keyed to your phone number. Conversation transcripts are kept for 7 days for context; your meal log, profile and coach notes are kept while your account is active.

Your controls

Message "memories" to see what the coach remembers, and "forget" to remove any of it.
Email hello@heycoach.chat to request a copy of your data or full deletion — we complete deletions within 30 days.
