User Reviews

Users consistently praise the extension for protecting real card details with virtual cards, easy cross-device autofill, and blocking/resolving unwanted charges. Recurrent complaints focus on new or broad permissions that collect device/browsing data, UX problems on some sites (and recent regressions), intrusive startup behavior, and limited customer support.
Pros
  • Creates and autofills virtual cards so you don't expose your real card number
  • Convenient and easy to use on desktop and mobile (including iOS), speeding checkout
  • Helps block unwanted charges and resolve disputed merchant charges
  • Features like monthly spend limits and a reasonable free tier were praised
Cons
  • Requires broad permissions and appears to collect device/browsing data (anti-fraud), raising privacy concerns
  • Recent UX regressions and site-specific autofill issues (some forms inaccessible)
  • Some users report intrusive behavior (opens a tab on browser start) and poor customer support/website reliability

I've been using this for about 4 years on both mobile, and desktop. It is hands down the best app I have. Some people say that they have some UX issues, for some websites that don't have accessible forms, I just paste the numbers manually. I love the functionality to limit the monthly spend per card and it has a very reasonable free tier... which I appreciate. I have never had any issues with the plugin being intrusive or constantly opening up pages, as other users have stated. A lot of the reviews here are concerning privacy... but of course you will have to allow the extension to see what you have on screen for it to autofill the card information. I have a separate Gecko based browser so that I can use extensions like this.

After ex-wife sues you for your bank records while hers are "privileged information" you really learn the value of an app like this. Been using it for years since.
