This policy applies to the Weight Gain Calculator app and website (“the app”).
We do not have user accounts and we do not collect your personal information on our servers. The details you enter (age, weight, height, target weight and similar) are used only to calculate results on your own device.
If you use the Diet Plan and Progress features, the app saves the profiles you create (name, age, height, target weight), your weight entries and your saved diet plans in your browser or device storage (localStorage). This data stays on your device. It is not sent to us or to any server by the app. You can create a backup file, restore it, or delete all data inside the app at any time. If you clear your browser data, uninstall the app or change your device, this data will be lost unless you have made a backup.
The app may show ads served by a third-party advertising network. These providers may use cookies, device identifiers or similar technologies to show and measure ads. We do not control the data they collect. Please refer to the privacy policy of the ad provider for details. The app does not use analytics tools of its own.
The app saves its own files in your browser or device cache so that it can work offline.
Results, diet plans and workout suggestions are estimates for general information only and are not medical advice. Food prices and nutrition values are approximate. Please consult a doctor or a qualified dietitian before changing your diet or exercise, especially if you have a medical condition, are pregnant, or are under 18.
The app is not directed at children under 13 and we do not knowingly collect any data from children.
If this policy changes, the new version will be posted on this page with an updated date.
