FAQ

Frequently asked questions

Why is Safari required for purchasing?

Device identification and installation rely on iOS system capabilities. The purchase journey therefore runs in Safari on the target iPhone or iPad. Public pages remain available in every modern browser.

Do quarterly and annual plans renew automatically?

No. The first release uses one-time purchases for fixed service periods.

Will a reinstall use an older signing app?

No. New installs, replacement signing, and reinstalls use the single current signing-app release.

Can I check signing progress?

Yes. Your order shows payment confirmation, certificate preparation, signing, and install readiness as readable steps.

Are English and Chinese customer records mixed?

No. They share infrastructure, while sessions, orders, device links, pricing, and notifications are separated by market.

Ready to manage more than one account on your iPhone?

Start with the Safari check, then choose your app and service period.
