Free and Pro share every feature. The only gap is account capacity — and this isn't a privilege for sale, it's this round's offering.
One-time buy, on the books for good. Two routes — take either.
Install PFEx from Google Play or the APK download and open your account.
Subscribe right in the store, one-time payment. If the store isn't an option, buy a redemption code on Xianyu and enter it in the app.
Back it once, grow the branch for good, and keep the books open.
Leave PFEx a review on Google Play, screenshot it, and email tech@greyglow.cn. Once verified, we send back a permanent redemption code.
Rate PFEx and say a few words on its Google Play page. A short note is plenty.
Capture the page showing your review went live, with your account and the text readable.
Mail it to tech@greyglow.cn with the subject "PFEx review code". We reply once it checks out.
Codes never expire, one per account. Seats already purchased on Pro are not issued twice.
