When initially downloaded, a free keypad of 12 Roald Dahl characters is presented, allowing the user to choose their own Picture Password sequence based on four of the image buttons. Each time the user wakes up their Android phone, the same 12 images appear on the keypad, but in a randomised order. When the correct four characters are chosen in the same order the device is unlocked. Alternative Roald Dahl keypads are available to collect via In-App purchasing.

The free App is based on the idea that it is easier to remember pictures than numbers. The App is also more secure than using a traditional keypad because the images shuffle and appear in a different order each time, instead of a static layout like almost all other keypads.

****Remember your keypad by telling yourself a story with the images****

During the set up process we ask for your details (email address) and give you a choice of a password reset options - either answer 3 control questions or use a button combination on the device. These can be used to help you reset your Picture Password.
Please note that if you forget your answers to the control questions or the button combination, YOUR DEVICE WILL BE LOCKED. We will send you an email with the answers to the questions and therefore you will need to access your email account via an alternative way in order to read this email.

The main reason to have this information is to help you reset your Picture Password. We will never provide this information to anyone else for marketing purposes, but we may (if you allow us to) send you emails about any new updates or new Apps we may launch.
The App will be available on Google Play for the following handsets sizes 4.6" to 10.5" and Android OS 4.1 TO 6.0. Full functionality may not occur on handsets outside of these sizes and Android OS software.

If you are not using your device, Roald Dahl Lock Screen will timeout at the time chosen in the ‘Screen timeout’ setting in your Settings – Display menu.
