How does billing work in the PercenX iOS app?

Subscriptions purchased through the PercenX iOS app are processed by Apple through the App Store.

Your purchase, renewal, payment method, and applicable billing details are handled through your Apple Account.

If you need to manage or cancel an Apple subscription, you can do so through your Apple subscription settings.

Tip: Make sure you're signed in to the same PercenX account you normally use so your subscription can be associated with the correct account.
