Where is my data stored?
Everything you log stays on your device. Macrion has no accounts and uploads nothing.
See the Privacy Policy for details.
The barcode scanner didn't find my product.
Barcodes are looked up in the Open Food Facts community database, which doesn't have
every product. You can still add the item manually, or use “Look Up Food” to search
the USDA database by name.
How are my macro targets calculated?
Macrion estimates your daily calories from the Mifflin–St Jeor formula and your
activity level and goal, then splits them into protein, carbs, and fat. These are
general wellness estimates, not medical advice — check with a healthcare professional
before making dietary changes.
Will my data sync to other devices?
Not currently — data lives on the single device where you entered it.
