Privacy

The short version

Prompto Sumo is local-first and BYOK (bring your own key). Your prompts, songs, and library live in your own browser. Your API keys go straight from your browser to the AI providers you choose — we never see or store them. The only data that reaches us is anonymous usage telemetry and any bug reports you choose to send (via TesterPayKit), which we use to improve the app.

What we process — and where it goes

• Your API keys (BYOK):stored only in your browser's local storage and sent directly to the OpenAI-compatible / Suno endpoints you configure. They are never transmitted to or stored on our servers.
• Prompts, songs & library: stored locally in your browser (local-first). We do not keep a copy on a server.
• Generation requests: your prompt text is sent directly to the AI provider you chose, under their privacy policy — not through us.
• Sign-in (optional): if you sign in with LinkedIn, we receive the basic profile info you authorize, solely to identify your session.
• Usage telemetry & bug reports: the app embeds the TesterPayKit SDK. It sends anonymous session/screen events and any bug report or feedback you submit to TesterPayKit (api.testerpaykit.com), operated by the same provider, to help us fix and improve the app.

Hosting
