Calnexia keeps your information on your device. There are no accounts, no sign-up, and no Calnexia server that stores your data.
We do not track you, show ads, build advertising profiles, or sell data. The full policy below simply explains this in detail.
Calnexia ("Calnexia", "the app", "we", "us") is a nutrition and weight-tracking application. The app is operated by Ciprian-Alexandru Frăsinescu, based in France. Once our company is formed, this operator will be updated to the registered legal entity.
For any privacy question, contact us at support@calnexia.com.
Because the personal information you enter stays on your device and is not transmitted to us, Calnexia acts as a data controller only for the limited processing described in sections 4 to 8 below.
Everything you log in Calnexia — your profile, weight entries, meals, food logs, goals, water intake, and progress — is stored locally on your device using your browser or device storage. This information:
Calnexia has no sign-up, no login, and no password. We never ask for your name, email address, or phone number in order to use the app. Any name shown in the app (for example, in a greeting) is stored only on your device.
If you choose to scan a product barcode, Calnexia asks your device for camera permission. The camera is used only while the scanner is open, and only to read a barcode.
When you scan a product barcode or type a food name into search, Calnexia sends that barcode number or the words you typed to Open Food Facts, a free public food database, in order to retrieve nutrition information.
This request contains the barcode number or search text and standard technical information (such as your device's IP address) that is part of any internet request. It does not include your profile, your logs, or any other personal data. Open Food Facts handles this request under its own privacy policy — see openfoodfacts.org/privacy.
Calnexia offers an optional feature that connects to Apple Health. If you choose to turn it on and grant permission, Calnexia reads your Active Energy Burned from Apple Health and uses it to adjust your daily calorie budget so it reflects how much you have actually moved.
If you buy a subscription or a one-time upgrade, the purchase is processed entirely by Apple through the App Store. Calnexia never sees or stores your card number or billing details.
We receive only a confirmation that a purchase is valid, so the app can unlock the relevant features. Apple's handling of payment data is governed by Apple's own privacy policy.
Calnexia does not include any third-party analytics or crash-reporting tool (such as Google Analytics, Firebase, Crashlytics, or Sentry). If you have chosen, at the iOS level, to share analytics and crash data with app developers, Apple may provide us with anonymous, aggregated crash reports through its own systems — for example, the device model, the iOS version, and where in the code an error occurred. These reports are collected and anonymized by Apple, are not linked to your identity, and are used only to fix bugs.
Calnexia is intended for people aged 16 and over and is not directed at younger children. If you believe a child has used the app, simply remove the app and its data from the device, as described in section 12.
If you are in the European Union, the United Kingdom, or another region with similar laws, you have rights over your personal data, including the rights of access, correction, deletion, and portability.
Because Calnexia stores your information only on your device and we hold no copy, you can exercise these rights directly and immediately:
If you have a question or a complaint, contact support@calnexia.com. You also have the right to lodge a complaint with your local data protection authority — in France, the CNIL (cnil.fr).
You are always in control. To erase everything Calnexia has stored:
Once deleted, the data cannot be recovered, because no backup exists outside your device.
Your information is protected by the security of your own device and operating system. We recommend keeping your device updated and protected with a passcode or biometric lock. Connections the app makes to the internet (for barcode lookups and purchases) use encrypted HTTPS.
We may update this policy as the app evolves. When we do, we will change the "Last updated" date above. Significant changes will be communicated within the app where appropriate. Continuing to use Calnexia after an update means you accept the revised policy.
