Optional Google Analytics
Google Analytics is blocked by default and is loaded only after you choose Accept. It is used to understand site usage and improve Rythero. Advertising storage and ad personalization remain disabled.
Privacy
Privacy, without the noise.
Rythero tries to process on your device anything that does not need to leave it. When a feature requires advanced AI music analysis, that is disclosed before data is sent.
Cloudflare
Rythero is delivered through Cloudflare and uses Cloudflare Web Analytics for traffic and performance measurement.
Local technical analysis
Audio Analyzer and Signature Lab's technical mode decode and measure the selected file inside your browser. In this mode, audio is not sent to the server. Reusable profiles may be stored in your browser's local storage.
AI music analysis
If you explicitly choose Analyze music with AI, the browser creates a smaller derived excerpt from early, middle and late parts of the track. That excerpt — not the complete original file — is sent to Rythero's backend and then to the configured AI provider to interpret general musical traits. Rythero does not intentionally store those analysis files after processing the request.
AI provider
The advanced version is prepared for the Google Gemini API. Provider-side processing and technical retention are governed by its API terms and project configuration. Rythero requests non-conversational storage to be disabled where the API supports it. Before this feature is offered broadly in production, it is intended to use a billing-enabled API project with appropriate privacy controls.
What Signature Lab does not try to extract
Signature Lab is designed to describe transferable high-level musical traits. It does not aim to recover an original prompt, identify artists, transcribe lyrics, clone voices or return melodies from a reference work.
Your choice
AI music analysis starts only when you press its button. You can use local technical measurements without invoking it. You can also accept or reject optional website analytics without losing site access.
Cookies and local storage
For details about Google Analytics cookies and the local preference used to remember your choice, see the Cookie policy.
Controller information still required
This pre-launch notice is not the final legal privacy notice. Before Rythero is actively promoted as a public service, it must include the full legal identity and contact details of the data controller.
