## 1. Executive Summary

InstaExtract solves the fundamental challenge of Instagram follower audits:
Finding out who does not follow you back without violating Meta's terms or triggering automated account checkpoints.

Most third-party mobile tracker apps in the iOS App Store or Google Play Store violate user security by:
1. Collecting plain-text Instagram credentials.
2. Sending API calls from server datacenters (AWS, DigitalOcean, Linode) across disparate geographic IP ranges.
3. Rapidly issuing unthrottled requests that trigger Meta's edge heuristic security filters (resulting in `checkpoint_required`, phone verification challenges, or permanent account locks).

InstaExtract eliminates these risks by running all extraction logic locally in the user's browser, communicating with Instagram via their authentic session cookie and residential ISP address.

## 2. Core Relational Terminology

InstaExtract classifies Instagram relationships into 5 distinct categories:

1. **Don't Follow Back (`not_following_back`)**:
   - Accounts where `followedByViewer == true` and `followsViewer == false`.
   - These represent accounts the user is following who do not reciprocate the follow. These are prime unfollow candidates.

2. **Fans / Admirers (`fans`)**:
   - Accounts where `followedByViewer == false` and `followsViewer == true`.
   - Accounts following the user that the user has not followed back.

3. **Mutual Friends (`mutuals`)**:
   - Accounts where `followedByViewer == true` and `followsViewer == true`.
   - High-trust reciprocal connections.

4. **All Followers (`followers`)**:
   - The complete set of accounts following the user (`mutuals` + `fans`).

5. **All Following (`following`)**:
   - The complete set of accounts the user follows (`mutuals` + `not_following_back`).

## 3. The "Method B" Mobile Hand-off Protocol

Mobile browsers lack developer tools and cannot easily access session headers. To provide an optimal mobile experience without security compromises, InstaExtract implements **Method B**:

1. **Extraction on Desktop**: The user initiates a 1-click Bookmarklet or pastes their paged cURL query on `https://instaextract.in` on their laptop.
2. **Analysis in Browser**: The browser engine traverses paginated edges with humanized jitter (1.5s - 2.5s) and computes set intersections in JavaScript.
3. **Ephemeral Sync**: If the user clicks "📱 Scan to Review on Mobile", the client creates an ephemeral session in AWS S3 (`POST /api/sessions`).
4. **QR Code Display**: A dynamic QR code is displayed pointing to `https://instaextract.in/dashboard.html?session=<uuid>`.
5. **Mobile Review & Native App Deep-Link**:
   - The user scans the QR code with their smartphone camera.
   - The mobile browser loads the responsive single-column card view.
   - Tapping "Open ↗" executes the mobile URI scheme: `instagram://user?username=<username>`.
   - This opens the exact user profile inside the native Instagram mobile app, allowing the user to tap "Following" -> "Unfollow" with one thumb press.
6. **Automatic 24-Hour Purge**: The AWS S3 bucket enforces an S3 Lifecycle Rule that permanently purges all session objects after 24 hours.

## 4. In-Browser Automation Safety Model

For users who wish to unfollow non-mutuals automatically, InstaExtract provides a client-side JavaScript runner:
- Executed directly inside the user's active `instagram.com` tab.
- Paced with realistic human delays: 30 to 45 seconds between unfollow actions.
- Includes a floating on-screen HUD with Start, Pause, Stop, and live progress bars.
- Zero credential transmission: uses the browser's existing CSRF token (`csrftoken` cookie) and origin headers.
