Data Deletion

Marcus AI runs as a local Docker application on your machine with your knowledge graph stored in your own Supabase project. That means there are three places your Marcus data can live, and you control all of them. This page walks through each.

1. Delete your local Marcus container

Marcus runs in Docker on your machine. Tear it down with one command:

cd ~/.marcus/compose && docker compose down -v

The -v flag removes the container volumes too, wiping any cached conversation history. To remove the install entirely:

rm -rf ~/.marcus

2. Delete your Supabase knowledge graph

Your Marcus brain — knowledge graph, memory, conversation history, OAuth tokens — lives in a Supabase project you created during install. To wipe it:

  • Go to supabase.com/dashboard
  • Pick your Marcus project (the one whose URL you pasted during install).
  • Settings → General → Pause project (data stays but inaccessible) or Delete project (data permanently destroyed).

If you used a fresh Supabase project just for Marcus (the recommended path during install), Delete project is the cleanest reset. If you reused an existing project, drop the marcus_test schema:

DROP SCHEMA marcus_test CASCADE;

3. Revoke OAuth tokens at each platform

Marcus stores access tokens in your local Supabase, but the authorization itself lives at each platform. Revoke there to prevent any chance of reuse:

Google (Gmail, Calendar, YouTube)

Meta (Facebook + Instagram)

  • Go to Facebook Business Integrations (Settings → Business Integrations).
  • Find "Marcus AI", click → Remove.
  • This revokes both Facebook Page and linked Instagram Business access in one action.

X (Twitter)

  • Go to X Connected Apps (Settings → Security and account access → Apps and sessions).
  • Find "Marcus AI", click → Revoke app permissions.

TikTok

  • Open the TikTok app → Profile → Menu (☰) → Settings and privacy.
  • Security and login → Authorized apps (or Manage account → Apps on web).
  • Find "Marcus AI", tap → Remove.

4. Request manual deletion

If you cannot complete the steps above for any reason — lost access to your Supabase project, can't find the authorization in a platform's settings, or want confirmation in writing — email us at [email protected] with the subject "Data deletion request" and the email address you used to sign up. We will:

  • Remove your row from the Build With Eman waitlist database within 7 business days.
  • Confirm the deletion in writing. If we cannot delete something (e.g., financial records under retention requirements), we will tell you what stayed and why.
  • Send you instructions tailored to your situation if any of the self-serve steps above don't apply.

What we retain after deletion

We may retain anonymized, aggregate usage logs (no personal data, no email addresses, no token contents) and any records required by US tax / financial regulations (typically up to 7 years for invoiced services). Everything else is destroyed.
