AnonFeedback's answer:
Employees in toxic workplaces, students under strict administrations, or junior staff members. Travelers with delayed flights, diners with bad service, or customers with slow internet. Job hunters checking a company's "red flags," parents looking for honest school reviews, or impulsive buyers checking product sentiment.
AnonFeedback's answer:
The Story of AnonFeedback It started with a completely different goal: I was building a standard, paid survey tool for businesses.
But during development, I realized something while talking to my friends. We all had feedback we wanted to share about our workplaces—frustrations, ideas, and honest critiques—but we were too afraid to say them. We realized that as long as a platform requires an account, there is a paper trail. If your details are in a database, you aren't truly anonymous.
So, I scrapped the original business plan. I removed the payment model and, most importantly, I deleted the login system entirely.
I built AnonFeedback.app to be the safe space I wished I had. A place where anyone can check, comment, and review the institutions in their lives without signing up, without tracking, and without fear.
