A video failed. Do I lose my credits?

No. Credits for a video that fails to render are returned to your balance automatically.

How do credits work?

Each video costs credits based on the model, length and resolution. The exact cost is shown on the Generate button before you tap it. Subscription credits refresh every period; credit packs never expire.

How do I cancel my subscription?

On iPhone: Settings → your name → Subscriptions → H3 Max. On Android: Google Play → Payments & subscriptions.

I got a new phone. How do I get my purchases back?

Open H3 Max and tap Restore on the paywall, signed in with the same App Store or Google account.

How do I delete my data?

In the app: Settings → Delete my data. This removes your account, uploads and videos permanently.
