FAQ
What do I actually get after payment?

We try to unlock the current environment first, while keeping your order record and backup activation key available for recovery if you ever need them.

Do future Pro features require another purchase?

No. Paid users continue to receive future Pro features within the same tier.

Will future pricing or promotions affect what I already bought?

No. New pricing or promotional changes apply to future purchases and do not rewrite completed orders or already active entitlements.
