Privacy Policy

For the iOS app Napf (public name to follow). As of 10 November 2026.

In short

The app has no account, no advertising and no analytics. Everything you record stays on your device: cats, weights, foods, photos and feedings. The developer receives no data.

What is stored on your device

The app stores the data you record locally on your device. It does not leave the device, except in the cases below that you start yourself.

Camera and photos

The app analyses photos of labels and barcodes only on the device. A photo is only saved if you keep it with the food. The app asks for camera access at the first scan.

Barcode lookup at Open Pet Food Facts

The barcode lookup is off by default. If you turn it on in the settings and a scanned barcode is not yet recorded, the app asks Open Pet Food Facts, an open database run by the Open Food Facts association in France. The barcode and the usual technical details of an internet connection go to this service, in particular your device's IP address. The app sends no other data about you and no personal identifier. How Open Food Facts processes these details is described in their privacy policy.

Backup and sharing

A backup or a shared file is only created when you create it. You decide in the iOS share sheet where it goes. A backup contains all your data with photos. Backups of your device by iOS, for example in iCloud, also contain this app's data; Apple's terms apply to them.

Deleting

If you delete an entry, it is gone. If you delete the app, iOS deletes all its data on this device. The developer holds no data that would need deleting.

Future features

A later sync between your devices via iCloud will extend this policy before it is released.

Your rights and questions

Under the Swiss Federal Act on Data Protection you have a right to information. As the developer holds no data about you, there is nothing to disclose. Questions: support@lab1337.ch.
