Instagram Checker by Berkat Tua Siallagan

Instagram Checker helps you quickly identify who doesn't follow you back on Instagram — safely, privately, and without compromising your account credentials.

Unlike third-party tools that ask for your password, Instagram Checker runs entirely locally in your Firefox browser. Your data stays on your device.

• No passwords required: Never asks for your Instagram password or login credentials.
• No server storage: No external database or cloud storage for your data.
• No tracking: No telemetry, analytics, or user activity tracking.

• Comprehensive Relationship Analysis: Identify Not Following Back, Fans, Mutual Followers, and 8 Meta connection categories.
• Full-Page Dashboard: Enjoy a dedicated browser tab experience instead of a small popup that can accidentally close.
• Cross-Tab Detection: Automatically communicates with your active Instagram tab.
• Direct Unfollow Workflow: Open Instagram profiles with one click and track your unfollow progress.
• Hide Unfollowed Filter: Keep your lists organized by hiding accounts you've already unfollowed.
• CSV Export: Export your results to a clean CSV file with protection against formula injection.
• Bilingual Interface: Switch between English and Bahasa Indonesia.

1. Make sure you're logged in to instagram.com in your Firefox browser.
2. Click the Instagram Checker extension icon to open the full-page dashboard.
3. Click Check to start reading your followers and following lists.
4. Review your results and export them to CSV whenever you need.

Your credentials and Instagram data never leave your device. All data processing and calculations happen locally inside your browser using standard browser APIs.

No account credentials are collected, and no external server is involved in processing your results.
