The SharinPix mobile app has a Settings screen accessible from the app's Home screen using the gear icon on the top right:

The Settings screen includes:

• The Clock icon at the top right is used to access your device's history of jobs/batches/pictures.
• The version of the app currently installed.  This example shows that version 2.6.15568 has been installed on the device.
• The Device ID is an essential piece of information when reaching SharinPix Support for assistance or troubleshooting. The support team uses the Device ID to identify the device and its corresponding logs.
• The Send feedback button is used to send feedback or report bugs. When reporting, please also include your email and a brief description of the issue.
• The Clear cached files button will delete all cached files downloaded online, such as PDFs. The device should be online to download again. 
• The Delete synchronized jobs button deletes all images and form checklist data already uploaded to Salesforce. This can be done at any time without any risks as long as the upload has been completed since a copy of those images already exists on SharinPix servers.
• The Delete all jobs button is used to delete all the data from the device (including the images, form checklist data not yet uploaded, and cached files). WARNING: DO NOT USE THIS OPTION UNLESS REQUIRED OR INSTRUCTED BY YOUR ADMIN OR SHARINPIX SUPPORT.
• The Export all files button exports all files from every job to the device's internal storage.
