光显 · Support

Free trial & purchase

光显 offers a 7-day free trial with watermark-free exports during the trial. After the trial, exports include a watermark. A one-time purchase of the “Pro” version removes the watermark permanently, and future features are free upgrades.

I got a new phone — how do I restore my purchase?

Open “Membership” and tap “Restore Purchase,” then sign in with your original Apple ID to restore your lifetime access — no need to pay again.

My exported video has a watermark?

Exports include a watermark after the trial ends if you haven’t purchased. Once you buy the “Pro” version, exports are watermark-free in full HD.

Which devices are supported?

iPhones running iOS 17.0 or later (iPhone XS / XR and newer).

Will my footage be uploaded?

No. All color grading, editing, and exporting happen locally on your device. The app never uploads any photos or videos — your privacy is safe.

How do I uninstall the app?

On the Home Screen, press and hold the “光显” icon and choose “Remove App → Delete App.” Your Pro purchase is tied to your Apple ID; after reinstalling, tap “Restore Purchase” in “Membership” to recover it — nothing is lost.

How do I request a refund?

In-app purchases are handled by Apple, so refunds must be requested from Apple: go to reportaproblem.apple.com, sign in with the Apple ID used for the purchase, find your “光显” purchase, choose “Request a refund,” enter a reason, and submit. You can also start from iPhone “Settings → Apple Account → Media & Purchases → Purchase History.” Whether a refund is granted is decided by Apple.
