I have used Ibotta for about 10 months and have received about $200 in cash back. That's the good news.
The bad news is I made my first online purchase through Ibotta recently and within six hours, my bank was contacting me because someone hacked my credit card info. The hacker made an unauthorized purchase and attempted to make two ATM withdrawals.
I have been exchanging emails with Ibotta's customer service about the hacking issue. They apparently don't have anyone who investigates cyber security issues because they just keep telling me they take your personal data seriously and have a 256-bit bank level encryption. So... that doesn't explain how my credit card info got hacked and how they are going to prevent it from happening again to me or someone else. I will NEVER make an online purchase through the Ibotta again.
