*Introductory pricing applies for a limited time only. Pricing is based on image files supplied files in JPG format, and audio files supplied as MP3. However, a nominal surcharge may apply if format conversion is required (i.e. if files are not in JPG or MP3). We will advise if any such surcharges apply, prior to configuring your image-audio pair to work with the BookPlayAR app. Once your configured files are downloaded by the BookPlayAR app, they are stored locally on the device. However, included in your setup cost is 24 months of storage of your configured files on our server, as a temporary backup of your configured BookPlayAR files. During this period, the BookPlayAR app can download them again, if ever they are needed.
