straight from the app.
Grumzi reflects your day. Never your worth.
Your health data never leaves your phone.
- Meals & workouts are stored on-device only — never uploaded.
- Apple Health access is read-only — and the code that reads your steps has no internet access.
- Meal photos are parsed once and deleted the moment the result arrives — never stored.
- An account is optional — it syncs only your profile, streak, and ⚡ summary. Never meals, never steps, never calorie values.
- No ads, ever.
Free feeds the hamster.

Fair questions.
Is grumzi a diet app?
No. We're not a calorie tracker, not a diet app, not a nutritionist. It's a game that makes you more aware — a pet that reflects your balance, never a judge.
So where do the calories go?
They exist — backstage. AI estimates them to compute Grumzi's vibe, but no calorie, target, or percentage ever appears on screen.
What do I actually see?
Severity tags (light / regular / heavy / feast), what a meal equals in movement, ⚡ energy that only goes up, the vibe pill, and Grumzi's scenes.
What if I go overboard?
Grumzi might lounge on the recliner for a bit. That's the whole consequence. "Worth it 🥹 Tomorrow we reset 🌱" is an actual line from the app.
Is my data private?
Yes: on-device storage, read-only Apple Health, photos parsed once and deleted, no ads. See the Privacy section above.
iPhone only?
At launch, yes. Android is next — join the waitlist and we'll ping you.
Grumzi's waiting.
Free to start. Kind by default.
