A calorie tracker with no account.

Why people want one

Why “no sign-up” is such a common search.

Type “calorie tracker no” into a search box and it finishes the sentence for you: “…no account”, “…no sign up”, “…no login”, “…that doesn’t sell data”. The reasons people give are sensible:

• Privacy. A food diary says a lot about your health, your routine and where you spend your evenings.
• Fewer leaks. Data that never sits on a server can’t leak from one.
• Speed. Open the app and start. No email, no password, no verification code at the table.
• No pressure. No marketing emails about how your week went.

Before you trust it

Seven questions to ask any “private” calorie app.

• Can I use it without signing in? Not “sign in later” — never.
• Where does my diary live? On the phone, or on their server?
• What goes over the network when it reads a photo? The whole photo? Your location? Faces in the background?
• Do my numbers go to analytics? Usage events are common; your actual entries shouldn’t be.
• Does it write to Apple Health or Health Connect? Handy for some people, unwanted by others — you should get to choose.
• Can I back up and move phones without an account? Look for an export or a backup to storage you own.
• Can I delete everything in one go?

The options

Calorie trackers with and without an account.

A word on OpenNutriTracker: its README says food searches go to Open Food Facts and its own backend, so it isn’t silent on the network — but nothing about you is tied to an account. Full trackers with accounts aren’t wrong, either: the account is what lets them sync across devices and the web.

How we do it

How PlateDiary works without an account.

To be complete: like most apps, PlateDiary uses limited usage and crash diagnostics, and purchases go through your app store. The privacy policy lists every provider. We make PlateDiary, so weigh that in.

• No PlateDiary account, ever. Your saves, notes, places and companions stay on your device.
• Calories are off unless you turn them on. When they’re on, a read sends small pictures of the cut-out dishes, with the place’s name as a hint — never the table photo, faces or your location. You agree once first, and nothing is kept on the server.
• Type it yourself. You can type your own number on any save without any AI at all.
• Calorie values never go to analytics, and nothing is written to Apple Health or Health Connect.
• Backups you own. A daily backup on the phone, an export you can save anywhere, and a copy in your own iCloud Drive or a Google Drive file you pick.
• Delete everything from Settings when you want a clean slate.

The trade-off

What you give up without an account.

• No web version and no sync between devices — the diary lives on one phone.
• If you lose the phone with no backup, the diary goes with it. Turn on the safe copy.
• Membership is restored through your app store, not a login.
• PlateDiary is not a full calorie tracker: there is no barcode scanner, no food database to search, no exercise and no weight.
