Frequently Asked Questions
How do I restore my subscription?
Open the app and go to Settings > Restore purchases. Your subscription is tied to your Apple ID, so it will restore automatically on any device signed in to the same account.
How do I cancel my subscription?
Subscriptions are managed by Apple. On your iPhone, go to Settings > your name > Subscriptions, select PipePrep AI, and tap Cancel Subscription. Cancelling stops future renewals — you keep access until the end of the current billing period.
Is the first test really free?
Yes. The first full-length practice battery is completely free — no subscription required. Upgrade only if you want the full set of batteries and unlimited access to Piper.
Do you offer refunds?
Apple handles all App Store billing, so refunds go through Apple's standard process. That said, contact us and we'll help you sort it out.
Which test does this prepare for?
PipePrep AI prepares you for the aptitude battery used by union plumbing and pipefitting apprenticeships — the timed test covering reading comprehension, numerical computation and reasoning, spatial folding, and mechanical comprehension.
How do I delete my data?
The app stores your practice data on your device — deleting the app deletes it. Email us for anything else and we'll take care of it.
Still stuck? Email pipeprepai@gmail.com with a short description of the issue (and your device model, if it's a bug) and we'll get you fixed up.
