Grinox 1.0

Quick answers for the yellow teeth selfie video maker. Everything below happens on your device, so most fixes are local.

Recording a prank video

Open Studio, pick a teeth shade, tap Start Camera, then tap the shutter to record up to 15 seconds. Review the take, tap Confirm & Generate Video, and save the finished clip to your photo library.

The shade is not showing on my teeth

Grinox draws on the mouth area of the frame and only when a mouth is detected. Keep your face toward the front camera, smile with your teeth showing, and watch for the “Mouth locked” pill before you record. Frames without a detected mouth are recorded untinted, and the viewfinder tells you so.

What costs a Creation Credit?

Only the final generation. Changing shades, moving the density slider and auditioning sounds are free. If a render fails or you cancel it, no credit is used. Re-saving or exporting a finished video is always free.

My credits are gone after reinstalling

Creation Credits are consumable items that live inside this app's storage on this device. Removing the app or clearing its data removes them, and they cannot be restored. Generate and save the videos you want to keep first.

Camera, microphone or photos are blocked

Open the iOS Settings app, find Grinox, and turn on Camera to use the viewfinder, Microphone to keep live sound, or Photos to save finished videos. Grinox never replaces the camera with the photo library, so a missed camera permission is never worked around.

Delete my data

Settings has Clear All Data. It shows what will be erased and asks you to confirm before it wipes your videos, takes, looks and remaining credits from this device. Videos already saved to your photo library are not touched.

Refunds

All purchases are handled by Apple. Refund requests are made through your App Store account, and if a purchase is refunded only the unused part of that purchase is removed.
