Privacy Policy

Last updated: May 8, 2026

This page describes what data Studio Buddy collects, where it lives, and how to remove it. The product handles audio-mixing conversations for individual Logic Pro users on macOS; the footprint is deliberately small.

What we collect

  • Account data — email address, a Supabase-managed password hash, and a Stripe customer ID once you subscribe.
  • Chat content — the messages you send to the agent and the assistant replies, stored locally on your Mac only. The server never persists them beyond the in-flight request.
  • Usage counters — per-billing-period token counts and request counts, used to enforce the monthly plan budget.
  • Crash / bug reports — if you flag an assistant reply or submit a bug report, the flagged text (and any note you add) is stored server-side so we can investigate.
  • Shared conversations (default on; opt-out in Settings)— your messages, the assistant replies, and the tool-call summaries from each completed turn are uploaded so we can review them and improve the product. Audio and screenshots are never included. This is on by default for new accounts so we can learn what works and what doesn't while the product is early. You can turn it off any time in the Companion app under Settings → Privacy; once off, no further turns are uploaded.

Where it lives

  • Supabase — account credentials, subscription state, usage counters. US region.
  • Stripe — billing identifiers and invoices. Stripe-owned infrastructure.
  • Anthropic— message content is forwarded to Anthropic's Claude API at request time to generate replies. Anthropic's retention policy applies; we do not store the content ourselves.
  • Vercel— runs the `/api/ai/chat` proxy and serves this website. Request metadata (IP, user-agent) passes through Vercel's edge logs per Vercel's standard retention.
  • Your Mac — chat threads, conversation history, song briefs, and the plugin-streamed audio analysis live entirely on-device at `~/Library/Application Support/StudioBuddy/`.

Audio data

The JUCE plugin computes metrics (loudness, spectral balance, stereo width, phase correlation) on your tracks and sends only those metrics — numbers, never raw audio — to the companion on `localhost:51234`. None of your actual audio ever leaves your machine.

Analytics and cookies

This site uses Vercel Analytics for anonymous page-view counts. No tracking cookies. Only the Supabase session cookie is set after you sign in, and it's required for the site to recognize you across pages.

Deleting your data

Email support@studiobuddy.ai from the address on your account. We remove your Supabase account, subscription record, usage history, and any flagged-reply notes within 7 days. Local on-device data you control directly — delete `~/Library/Application Support/StudioBuddy/` to wipe it.
