Users cannot grant granular, app-specific permissions or provide dummy profile data when signing in with GitHub, forcing an all-or-nothing choice between not using the service or exposing all requested real data.

Existing GitHub OAuth permissions are too broad and binary; users cannot selectively grant access to specific real data fields or substitute dummy values, which forces privacy compromises.

App Concept

PhantomProfile OAuth Proxy

A privacy middleware that intercepts OAuth requests and lets users create app-specific virtual profiles with granular data controls. It allows users to decide which real data fields to share and which to replace with dummy values, without the app knowing. This restores user control and privacy without requiring changes from service providers.

Key Features

Granular permission toggles for each OAuth data field (e.g., real email, dummy name)
App-specific virtual profiles with persistent dummy identities
Transparent proxy layer that works with existing OAuth flows
Dashboard to manage and revoke per-app data access

Target Users: Privacy-conscious end users who frequently authenticate with GitHub or other OAuth providers for third-party apps and services.

Revenue Model: Freemium with $5/mo premium tier for unlimited profiles and advanced controls
