FAQ

Does Waveform Generator send my data to a server?↓

No. Waveform Generator runs entirely in your browser. Your inputs, results, and any uploaded files stay on the device, never reach our servers, and are not used for analytics or advertising. The only network traffic is the page itself loading.

Are there usage limits or rate caps?↓

No. There is no account requirement, no daily quota, no rate limit, and no paywall. Use Waveform Generator as often as you need across as many sessions as you want — outputs are not throttled and the tool does not nudge you toward a paid plan.

Can I use Waveform Generator on mobile?↓

Yes. The interface is responsive and works in mobile browsers (iOS Safari, Android Chrome) without an install. Touch targets are sized for finger input and the layout adapts to portrait orientation. Performance depends on your device, but most modern phones handle the workload comfortably.

Is Waveform Generator free for personal and commercial use?↓

Yes. There is no licensing fee, no required attribution, and no advertising on results. Use the tool and its outputs freely in personal projects, internal tooling, freelance work, agency deliverables, and product launches. No terms restrict commercial use.
