The basics

What is MSRX Calorie AI?

A private food, portion and calorie-burn tracker. You log what you eat and what you do, and it shows your day as food in, resting burn and activity burn, with the balance at the top. It comes as an iPhone app and as a web app at calorie.msrx.co.in/app.

What does it cost?

Nothing. There are no ads, no subscriptions and no in-app purchases.

Who makes it?

Mrinal Singh Raja, an individual, under the brand "MSRX". MSRX is not a company. See msrx.co.in for the other MSRX apps.

Privacy

Where is my data?

On your own device. The web app keeps it in your browser's storage. The iPhone app keeps it on the phone. There is no account and no server copy. Read the Privacy Policy.

Does anything get sent to MSRX?

No. There is no analytics, no tracking and no advertising. Opening the page sends the usual request to the hosting provider to fetch the app's files, but not your diary.

Can I use it without an account or internet?

Yes. After the first visit the web app works offline, and you can install it from your browser like an app.

Web app and iPhone app

What is different on the web?

The web app has food search, portions with hand measures, describing a meal, saved meals, activity and burn, the daily balance, insights, weight, water and fasting. Photo and voice logging, Apple Health, reminders, widgets and Siri need the iPhone app. Describing a meal on the web is a food-list lookup, not an AI model, and you review it before saving.

Can I move data between them?

Yes. In the web app open Me, then Export JSON. The iPhone app exports and imports the same format. Importing only adds records that are missing and never deletes anything. There is no automatic sync.

Will my data be lost if I clear my browser?

Clearing site data removes it, and a browser may clear it when storage runs low. Export a backup now and then.

Numbers and accuracy

How is the daily target set?

From the Mifflin–St Jeor formula, your activity level and your goal. After about a week of logs and weigh-ins it can learn your real expenditure from your own data. A safety floor stops targets from going too low.

How is calorie burn worked out?

Resting burn is 1.2 times your estimated resting energy, counted through the day, even while you sleep. Activity burn is (MET − 1) × weight × hours, so resting burn is never counted twice. Balance = eaten − resting − activity.

How accurate are the food values?

They are approximate values per 100 g from public tables, and home cooking varies. Treat every figure as an estimate.

Is this medical advice?

No. It is a general wellness tool. Talk to a clinician before changing your diet, especially if you are pregnant, under 18, managing a medical condition or have a history of disordered eating.

Your data

How do I delete everything?

Web: Me, then Erase all data. iPhone: Profile, then Erase all data. We hold none of your data, so there is nothing to delete on our side.

Where are the legal terms?

In the Terms of Use, which include the disclaimer and the zero-liability clause.
