The Recipe Box version 6.0 and later does not collect or transmit any of your personal information. It does not include any third party libraries which collect or transmit user data, nor any third party tools at all. To delete the data The Recipe Box does store, simply delete the app. (This will also delete all your recipes and app settings).
Previous versions of the app used the third party tool Fabric to analyze poor app behavior. No version of the app has asked for or made use of personally identifying information.
Your recipes are your recipes. Your data is your data. We don't need to know anything about how you use our app to run our business. You buy it, it's yours.
