Frequently asked questions
The short version of how Calvero counts calories from a photo, what it costs, and how your data is protected.
How does Calvero count calories from a photo?
Take a photo of your meal or upload an existing one (JPG, PNG or HEIC). The AI recognises the foods and portion size and estimates calories, protein, fat and carbs. The result goes straight into your daily diary.
How accurate is counting from a photo?
Calvero gives an estimate from the image, not a lab analysis. If the AI gets a dish or portion wrong, correct it in words — for example "that was 200 g of buckwheat" — and Calvero recalculates. The clearer the food is in the photo, the better the estimate.
Do I need to weigh my food?
No. The AI estimates portion size from the photo. But if you want more precision, you can specify the weight or ingredients in text and Calvero will take it into account.
What are macros and the progress rings?
Macros are calories, protein, fat and carbs. Calvero shows them for the day in clear rings: you can see how much you've eaten and how much is left to reach your goal.
Can I use Calvero in Telegram?
Yes. Link your account to the Telegram bot and send photos of your food right into the chat — you can count calories without opening the app.
Is there a free trial?
Yes. There's a free trial with a few analyses so you can judge the accuracy. No card is required to start.
How much does the subscription cost?
After the trial, Calvero runs on a monthly subscription with no hidden fees. See the current price in the Pricing section on the home page.
How do I pay and how do I cancel?
Payment goes through Tribute in Telegram. You can turn off auto-renewal in the @tribute bot — access stays active until the end of the period you've already paid for.
What devices does Calvero work on?
Calvero works in the browser on any device and in Telegram. There's no separate app to install.
What happens to my photos and data?
Photos are used to recognise the dish and count macros. How we process and store data is described in detail in the Privacy Policy on the site.
Is Calvero suitable for losing or gaining weight?
Calvero is a tool for tracking calories and macros, not medical or dietary advice. It helps you see what and how much you eat. Discuss weight goals, diets and any health questions with a doctor or a certified dietitian.
