Keeper of Paintings and the Mischievous Masterpieces App  

Terms and Conditions for Adults

Using the app  

The app will require camera and motion and orientation permissions from your device to use the basic functions.   

All photos taken as part of this experience are only stored on the device and within the app for the session of painting creation and only processed for this purpose. After the painting exercise is completed, the raw photo is deleted by the device and not stored anywhere on your personal or provided device.  

Any painting that you choose to create is stored locally on the app memory and can be downloaded to your device. If you choose to reset the app then all painting data will be deleted, and progress reset.   

Anonymised data about user’s experience of the app will be collected via Firebase (Google Analytics). You can view all of the anonymised data areas that the app collects on the App Store pages for this experience. If you would like to check ARCADE XR’s privacy policy for the kinds of data that we collect as part of our experiences, you can do so here:   

Submitting your paintings to the National Gallery

You can choose to share your created painting with the National Gallery via a secure submission process. You must consent before sharing your paintings via a tick box which asks if you have read and understood the attached terms and conditions. You can completely skip the whole submission process if you wish.

All paintings that are submitted will have to be accompanied with an 'Artist Nickname' and 'Painting Name' of your own invention. The paintings and the two names should not contain any personal data, i.e. you/your child should not be identifiable on the painting, and you/your child should not share a real name or any other personal information.  Children are requested to ask their parents or guardians or an Art Road Trip facilitator to verify no personal data is given before submission.

The paintings are transferred via https directly from the app to a secure back-end dashboard which can only be accessed by National Gallery or ARCADE XR personnel via unique password protected credentials.  ARCADE XR will provide hosting services for the backend dashboard using a scalable and secure server configuration. Paintings will not be accessible or visible outside of this database.  

Using your paintings  

The National Gallery reserves the right, at its sole discretion, to choose to include or not include submissions for use in the Gallery, on its website or social media. You agree to grant the National Gallery the non-exclusive, worldwide, perpetual, royalty-free right to reproduce, modify, edit, publish and distribute your artwork/the artwork of your child(ren) in the National Gallery, on its website and social media for any length of time.   

You must own all the rights to any material submitted. You may not submit any painting that defames any person, invades their privacy, infringes their trademark or other rights, or which is otherwise unlawful.  

The National Gallery will ensure it complies with the requirements of all legislation and regulatory requirements in force from time to time relating to the use of the Paintings. Especially, the National Gallery will delete any painting or Artist Nickname or Painting name that might contain personal data.   

For more information on how the National Gallery will process and delete or anonymise all personal data that might be submitted through the app, please read the privacy notice:

Terms and Conditions for Children  

Make sure you read these Terms and Conditions with a parent/guardian so you know all the rules and understand what we do with the information you send us.  

If you decide to submit your painting to the National Gallery, it might be used by the Gallery, for example, in displays within the Gallery or on its website or social channels. It means that you are happy for the National Gallery to use them and for any length of time (or not use them at all). If your parents/guardians are with you, please ask their permission before you submit your work!  

The National Gallery will check everything you send before they publish it so please try and make sure that your painting isn’t rude or upsetting.

Do not share any personal information! 

If you are taking a photo of yourself or someone else to create your painting, make sure you and they are OK to be included. Be creative and let your imagination run wild! The National Gallery won't publish your paintings if the people on them look too much like their photos.   

We want you to invent an Artist's nickname and give your work a Painting name, so please don’t share your real name or surname with us or any other details about yourself (school name, home address…).   

Please ask you parent/guardian or, if they’re not there, an Art Road Trip facilitator, to check there’s no personal data in your artwork before you submit it.
