RYTHERORythero is designed to work without accounts or a cloud project library. Most creation tools run in your browser. When a feature needs external AI analysis, it says so before anything is sent.
Your form choices are processed in the browser. Style DNA is stored only if you choose “Save on this device”; up to five profiles can be kept in local browser storage. The latest Song Blueprint may also be kept locally so you can reuse it. Rythero does not receive those saved profiles.
Your selections and generated prompt are assembled in the browser. Rythero does not create an account or cloud copy of the prompt.
Technical measurements such as duration, estimated BPM, level and dynamics are calculated locally. In local mode, the audio file does not leave your browser.
Technical analysis stays in the browser. A reusable Signature can be stored locally on your device so you can compare later results. It is not public.
Only when you choose AI analysis, Rythero creates a short derived excerpt from early, middle and late parts of the audio and sends that excerpt through the Rythero backend to Google Gemini for analysis. The complete original file is not intentionally stored by Rythero. Provider-side processing is governed by the provider’s API terms and project settings.
Local profiles are tied to this browser and device. Clearing site data or using another browser can remove or hide them because Rythero has no account-based cloud library.
