Frequently asked questions
What is PHV Prep UK?
It's a study app that helps drivers prepare for West Midlands private hire vehicle ("taxi badge") licensing exams (Wolverhampton, Birmingham, Solihull, Coventry, Tamworth, Sandwell, Dudley and Walsall), with practice questions, timed mock exams, progress tracking, and an AI Tutor.
Is Premium a subscription?
No. PHV Prep Premium is a one-off payment that gives you lifetime access. There is nothing to cancel and no recurring charge.
How do I restore my purchase?
If you've already bought Premium — for example on another device, or after reinstalling — open the Premium screen in the app and tap Restore purchase. Make sure you're signed in with the same Apple ID or Google account you used to buy it.
I paid but Premium isn't showing
First try Restore purchase on the Premium screen. If it still doesn't unlock, email support@yongchivo.com with the email address on your account and we'll sort it out.
How do I delete my PHV Prep UK account and data?
In the app: open the dashboard, go to Preferences, tap Delete account and enter your password. Your account is deleted straight away.
Without the app: email support@yongchivo.com from the email address linked to your account and ask us to delete it. We'll delete it and confirm by email within one month.
What we delete:
- your sign-in details (email address and password);
- your progress and exam history;
- your ratings and reports of AI Tutor answers.
What we keep, and for how long:
- Purchase record (if you bought Premium): kept with no personal data and no link to your account, for as long as we need it to handle refunds, prevent fraud and let you use "Restore purchase" on a new account.
- Server logs: deleted after up to 30 days.
- Database recovery data: deleted after up to 7 days.
- Usage analytics: not linked to your account; they expire on Google Analytics' schedule (event data after 2 months, user-level data after 14 months).
Your AI Tutor conversations are not stored on our systems, so there is nothing else to delete. Full details are in our Privacy Policy.
