How can we help?
Answers to the most common questions — and a real inbox if yours isn't here.
Is Nox free?
Yes. Nox is free to download, with no ads and no account required. The free tier lets you mix up to 2 sounds at once from the full 30-sound library. A single one-time purchase — "Nox Premium" — unlocks background/lock-screen playback, mixing up to 6 sounds, longer custom timers, all ready-made atmospheres, Nightstand mode, and unlimited saved mixes. It's a one-time purchase, never a subscription.
I bought Premium on one device — how do I get it on another?
Open Nox on your new device, go to Settings, and tap "Restore Purchases." As long as you're signed into the same Apple ID or Google account you originally purchased with, Premium unlocks instantly.
How do I get a refund?
All payments are processed by Apple or Google — we don't handle billing directly, so refunds go through their standard process: Apple's refund request page or Google Play's refund policy.
Does Nox collect my data?
No. Nox has no account, no analytics, and no tracking. Everything — your mixes, timer settings, theme — stays only on your device. See our Privacy Policy for the full details.
A sound isn't playing, or the app is acting up — what do I do?
Try force-closing and reopening Nox first. If that doesn't help, email us with your device model and iOS/Android version — we read every message.
