+## Frequently Asked Questions
+
+## Can I use this app completely offline?
+
+Currently, you only need the network connectivity to load the application. Once it's loaded, it can be used without access to the network.
+
+In the future it may evolve in a [progressive web application](https://en.wikipedia.org/wiki/Progressive_web_app) so it can be installed and used completely offline.
+
+## Where does this app stores my data?
+
+Your data is exclusively stored in your browser's local storage. Nothing is sent over the network.
+
+## I use multiple devices, how do I synchronize my data?
+
+Currently, because it is stored exclusively locally, you cannot synchronize your data.
+
+This is a deliberate choice. In the future there may be a way to export it, but not automatically and in no circumstances over the network.
+
+## Do I have to write my secret-key by hand?
+
+Not at all! If your key is represented by a QR code, you can scan it.
+
+## How do I generate a QR code with my key?
+
+From the command line you can use the [qrencode](https://fukuchi.org/works/qrencode/) tool. Most Linux distributions and BSD systems have this tool in their packages or ports.
+
+You can generate a new secret key and display it both in a base64 string and a QR code using the following command:
+
+```
+secret_key="$(openssl rand -base64 16)" && echo "Secret key: ${secret_key}" && qrencode -t utf8 "${secret_key}" && unset secret_key
+```
