Frequently Asked Questions
Is it safe to use this Instagram unfollower checker?
Yes, completely safe. The analysis runs locally in your browser. The JSON files you upload are never sent to any server. We don't ask for your password or account access, so it's impossible for your account to be hacked or suspended.
How long does Instagram take to send my data?
Instagram usually takes between a few minutes and 48 hours to prepare your data. You'll receive an email with a download link when it's ready. For accounts with many followers, it may take longer.
Where do I find the followers.json and following.json files?
After downloading and extracting the ZIP file from Instagram, look in the 'connections' folder, then in 'followers_and_following'. There you'll find the required JSON files.
Can I use this tool on my phone?
Yes! It works perfectly on mobile devices through your browser. Download your Instagram data, save the JSON files to your phone, and upload them here.
Why is this safer than apps that ask for my password?
Instagram suspends third-party apps that access its API without authorization. Apps that ask for your password risk getting your account permanently blocked. Our tool is safe because we never access your account - we only analyze files you download yourself.
Can my Instagram account be blocked for using this?
No, it's impossible. We only work with JSON files you officially download from Instagram. There is no interaction with the platform. Instagram doesn't even know you're using this tool.
How often should I check my unfollowers?
We recommend once a month, or every 2 weeks for influencers or businesses. Remember that losing some followers is normal - focus on creating quality content.
Does this work for business and creator accounts?
Yes, it works for all account types: personal, business, creator, or influencer, regardless of follower count. Our system handles data efficiently even with millions of followers.
Can I recover followers who unfollowed me?
You can try to reconnect, but we don't recommend sending bulk messages or repeatedly following/unfollowing. Focus on improving your content and engaging authentically with your audience.
Is this tool really free?
Completely free with no tricks. No premium versions, hidden payments, subscriptions, or usage limits. We're supported by advertising to keep the service free for everyone.
