What we collect
This tool does not store or upload your original audio or image files. All processing happens in your browser — audio decoding, waveform rendering and video export are performed entirely on your device.
With your consent, we collect anonymous usage behavior data only, including:
- Event counts such as “audio uploaded”, “video generated”, “video downloaded”
- Parameter adjustment trajectories (parameter names only, never values)
- Aggregated generation results: success rate, rendering duration, export format
- Design configuration of downloaded works (colors, aspect ratio, animation style) used to improve future templates
- A random session identifier generated in your browser (
aud_prefix), page path, device type and a hashed/bucketed referrer category
We never collect: audio or image file contents, title/author text you type, or any personally identifiable information in original form.
How we use it
Anonymous, aggregated data is used to improve the tool (e.g. which waveform styles and color combinations are most useful) and for product improvement and industry insights. Data is never sold or used to identify individuals.
Retention
Anonymous event data is kept locally in your browser for 90 days; on the server side it is archived for 30 days and then deleted. Your “My history” records are stored only in your browser’s local storage and never uploaded.
How to withdraw consent
Open the tool’s home page and use the “My history” panel → “Withdraw consent & clear all local data”. This clears your local history, withdraws your consent and resets the session identifier. You can also clear site data in your browser settings at any time.

Compliance statement
This tool does not store or upload your original audio or image files. All processing happens in your browser. Anonymous statistics are only collected after you press “Accept” in the consent banner, and refusing consent never limits any feature.
