The simple answer is yes. In fact, no data is actually moved outside your device. Currently, we don’t use cloud storage or any external data storage to handle your information. The information you put into the application is stored within the browser in something called Local Storage. With local storage, web applications can store data locally within the user’s browser. Before HTML5, application data had to be stored in cookies, included in every server request. Local storage is more secure, and large amounts of data can be stored locally, without affecting website performance.
What about in the future? In the future, we would like to add the option of storing your data in the cloud so that you can share the information across devices. This way, you can see the same information on your laptop as you do on your mobile phone. We will do everything to keep this data safe, secure and most importantly anonymous. We will never ask for names, accounts, passwords, or anything of that nature so rest assure, your data is secure.
