Calvio

Calvio privacy policy

Calvio, the AI calorie tracker for iPhone, by JARAMAH INC. Last updated November 4, 2026.

What stays on your iPhone

Everything you log or save: foods and meals, saved meals, workouts, water, weight, goals, height, age and sex, and your settings. API keys you add are kept in your iPhone's Keychain. Settings → Delete account and all data, or deleting the app, removes it.

Your account

You can use Calvio without an account. If you choose Sign in with Apple, Apple shares a private ID and, the first time, your name and email if you allow it. These are kept on your iPhone only; we don't run an account server. Settings → Delete account and all data removes the account and everything with it.

What the AI receives

To estimate nutrition, the app sends our server (run on Cloudflare) the text you typed or said, a photo you chose of a meal, nutrition label or menu, or the name and address of a restaurant you picked. Our server passes it to OpenAI, which may search the web for published nutrition (for example USDA FoodData Central or a restaurant's nutrition page), and returns the answer with the pages it used. To estimate a workout, the app also sends your approximate body weight; to suggest dishes from a menu, how many calories you have left today and your goal (lose, keep or gain weight).

We ask OpenAI not to store these requests, and they aren't used to train AI models. OpenAI may keep requests for up to 30 days to detect abuse, then deletes them. Our server keeps no copy. It keeps only daily request counts for an anonymous device ID (a random number made by the app, or an Apple App Attest key), deleted after two days, to stop abuse and keep costs in check.

If you add your own Claude or OpenAI key in Settings, requests go straight from your iPhone to that company under your own account and their privacy terms. If you choose Apple Intelligence, it runs on your iPhone (or Apple's Private Cloud Compute) and nothing is sent to us.

Other services Calvio uses

• Apple Health (only if you turn it on): foods you log are saved to Health, and weight, height, age and sex are read to set your goals. Health data is never used for advertising, never sold, and never stored on our servers.
• Speech (when you tap the mic): Apple's speech recognition turns what you say into text, on your iPhone when possible. Only the text is used after that.
• Location (only when you look for places nearby): used on your iPhone with Apple Maps to list restaurants and stores. Your location is not sent to our server.
• Barcodes: only the barcode number is sent to Open Food Facts, a free food database, to look up the product.
• Nutrition labels and menus are read on your iPhone with Apple's text recognition before anything is sent.
• Subscriptions: Apple processes Calvio Pro payments, trials, renewals and refunds. We only learn from the App Store whether your subscription is active.

Estimates, not medical advice

Calvio's numbers are estimates and can be wrong. Calvio doesn't give medical advice; talk to a doctor or dietitian about your diet, especially if you have a health condition or a history of disordered eating.

Children

Calvio isn't directed to children under 13, and we don't knowingly collect their information.

Your choices

You can turn off sending to AI companies, or switch to Apple Intelligence, in Settings → AI at any time; stop Health sharing in the Health app; and delete everything in Settings → Delete account and all data. Because we don't keep your journal on our servers, there is nothing else to delete; daily counts expire on their own. Cancel a subscription in your Apple Account settings.
