Privacy
Your data stays with you
Marcelo Fit has no accounts and keeps none of your information on a server. Here's exactly where it goes.
Saved on your phone
Your meals, workouts, weight and sleep are saved in the browser on your own device. Nobody else can see them.
What goes online
Food searches and barcode scans go to Open Food Facts, a free public food database. Meal photos, if you use them, go to Google’s free AI to recognise the food, and Google may use them to improve its services. Fridge photos for recipe ideas go to Google’s free AI in the same way. Walk maps load street pictures from OpenStreetMap; your route itself stays on your phone. Questions to the AI coach, if you ask any, go to Google’s free AI with a summary of what you logged. Walk weather, if you switch it on, sends your rough location (about 1 km) to Open-Meteo, a free weather service. No names or accounts are sent.
Back up any time
Download a backup file from Settings and restore it on a new phone. Clearing your browser data without one erases your log for good.
FAQ
Questions? We've got answers
Is Marcelo Fit really free?
Yes. There are no paid plans, no trials and no ads.
Do I need to create an account?
No. Tap Get Started and you can log your first meal right away.
Where is my data stored?
Everything is saved in your own browser on this device. When you search online or scan a barcode, only that search is sent to Open Food Facts, a free public food database, and a meal photo (if you take one) is sent to Google’s free AI. Fridge photos for recipe ideas go to Google’s free AI in the same way. Walk maps load street pictures from OpenStreetMap, but your route stays on your phone. Questions to the AI coach, if you ask any, go to Google’s free AI with a summary of what you logged. Walk weather, if you switch it on, sends your rough location (about 1 km) to Open-Meteo, a free weather service. If you clear your browser data, your log is cleared too, so download a backup from Settings now and then.
How do the activity rings work?
Move fills up with the calories you burn in workouts, Exercise with your workout minutes, and Stand with the hours you got up and moved. Close all three for a perfect day. You can change each goal in Settings.
How does the barcode scanner work?
Tap Scan next to the food search and point your camera at the barcode. You can also take a photo of it, or type the number printed underneath. Marcelo Fit then looks it up in Open Food Facts. If a product isn't there, add it to My foods once and it will be recognised every time after that.
Can I put it on my phone's home screen?
Yes. On iPhone, open it in Safari, tap the Share button, then "Add to Home Screen". On Android, open it in Chrome and tap "Install app" (or Menu, then "Add to Home screen"). It then opens full screen like any other app, and works without internet.
What if I get a new phone?
On the old phone, open Settings, then Backup & data, and tap "Download a backup". Send the file to your new phone (by email or messages, for example), open Marcelo Fit there and tap "Restore from a backup".
How many calories should I eat per day?
It depends on your age, size, activity level and goals. 2,000 is a common starting point, but a doctor or dietitian can help you pick the right number.
Ready to start tracking?
No sign-up and nothing to buy. Your first meal takes less than a minute to log.
