MealBrain Privacy Policy

Effective: [SET DATE AT LAUNCH] · Contact: houstonsmail@gmail.com

MealBrain is built privacy-first. Here is the whole picture, in plain English.

What stays on your device

• Your food log — every meal you log lives on your phone.
• Personal Food Memory — the foods MealBrain has learned from your corrections. On-device.
• Your goals, streak, and settings.

Deleting the app deletes all of this. An account is optional (see below) — without one, nothing here is kept anywhere but your phone.

What leaves your device (and why)

• Meal photos, only when you request an AI estimate. The photo is sent to MealBrain's secure server (our proxy), which asks an AI model for a calorie/macro estimate and returns the answer. Photos are processed, not stored. No AI vendor key exists in the app; the server holds it.
• Barcode numbers are looked up against the Open Food Facts public database.
• Restaurant lookups query MealBrain's menu library (read-only).

Global learning — disclosed up front, off in one tap

When you set up MealBrain, we ask whether to "Improve LogAI for everyone" (shown pre-selected; untick it and nothing is ever shared). While it's on:

• We receive your corrections anonymously: the food name, your corrected numbers, and (if you tagged one) the restaurant.
• Identified only by a random install token — no name, no email, no account, no device fingerprint.
• Never your photos.
• Aggregated corrections improve estimates for every user. Turn it off any time; nothing already shared can be traced back to you (we couldn't if we wanted to).

Apple Health / Health Connect

If you enable sync, MealBrain writes your logged calories and macros to Apple Health or Health Connect on your device. We read nothing back, and health data never touches our servers.

Beta feedback

If you tap the beta feedback button, your message and an optional screenshot go to our team to fix bugs. That's their only use.

What we never do

• We never sell your personal data. Ever.
• Free tier may show clearly-labeled sponsored suggestions chosen by context (like the screen you're on) — never by selling your profile, and with no third-party ad trackers. Pro is ad-free.
• We may publish or sell aggregate, anonymized trends (e.g. 'protein orders rose 30%') that can never identify you.
• No training AI on your photos.
• No regional price games — one flat price, stated up front.

Your account (optional)

Email sign-in with one-time codes, no password required. An account is only needed if you want to use Photo food diary backup (Pro). Otherwise, MealBrain works completely offline.

Photo food diary backup (Pro)

Pro members can enable cloud backup of their photo diary — you choose which photos to back up. Your photos are stored in your private, encrypted space and never shared, sold, or used for training. You can delete backed-up photos anytime; they're gone immediately. We never look at your diary photos except to restore them to your devices.

Community menu & dish photos (optional)

If you choose to snap a restaurant's menu or share a dish photo, that photo is contributed anonymously (a random install token, never your identity) to improve MealBrain's restaurant data for everyone. Menu photos are read by AI to extract item names and nutrition estimates. Only contribute photos you took yourself; don't include people in them. This is always an explicit button/toggle — nothing is ever shared automatically.

Location

When you log a meal, MealBrain asks permission to see your location momentarily — only to suggest the restaurant you're at right now. Your GPS coordinates are never stored on our servers and never attached to any meal entry or correction. Only the restaurant name gets saved with your log. Location is never used to build a profile of where you go, and you can deny permission any time.

Payments

Subscriptions are processed by Apple/Google and RevenueCat. We see your entitlement status, never your payment details.

Changes

Material changes to this policy will be shown in-app before they take effect.
