On your device, in the app's own storage. There is no cloud copy, because there is no cloud. Include the app in your iPhone backup (iCloud Backup or a computer backup) and your records travel with the phone when you replace it.
No, and this is worth being blunt about: we have no copy of anything. Restore the device from a backup. If there was no backup, the records are gone. This is the trade-off that comes with an app that never uploads your clients' details anywhere.
Open Your business and tap Restore purchases. As long as you are signed in with the same Apple account it will come back. Your jobs do not come back that way — those come from a device backup.
In the Settings app on your iPhone: tap your name, then Subscriptions, then Sitecase. We have no account system and cannot cancel it for you.
Yes. That is most of the point. Nothing in the app needs a connection except the App Store, and only to take a payment.
No. Sharing needs a server, an account, and a copy of your clients' details on somebody else's machine, and Sitecase is built to have none of those. If you have grown to the point of needing a second seat, a platform like Jobber or Housecall Pro is the honest answer.

Paper size follows your region rather than your language, so a report printed in the UK is A4 and one printed in the US is Letter without either of you setting anything.
That happens on a device with no camera, and in the Simulator. Use Add from photo library instead.
Tell us what you did, what happened, and which iPhone and iOS version you are on: minhnd410@gmail.com. There are no analytics in the app, so your description really is all we have to go on — the more specific, the better.
