AdLock Review 2025: A Truly Free Ad Blocker

AdLock is a high-performing app that works well against ads, trackers, and other online nuisances. Our testing proved this as AdLock received a perfect score with Adblock Tester and a near-perfect score with Cover Your Tracks.

With its dedication not selling your data and highly effective test results, AdLock is one of our favorite ad blockers. Even the pricing structure is affordable, and it comes with extras like filters to block spyware and social media tracking.

If you want a product that’ll reduce never-ending YouTube ads, AdLock might be the best ad blocker for you.

Overview

We last tested AdLock on March 18, 2025.

Our experience

We opted to purchase AdLock Premium so we could test its full capabilities. The Windows app provided an easy setup process, with tips and explanations on some of its features.

Once we installed the extension, it was pretty fun to test. We visited sites populated with ads like Forbes and YouTube to find a much more straightforward browsing experience. 

We also tested AdLock on iOS, which had a similarly thorough setup process. We were also pleased to find that you can block YouTube ads by streaming them from directly within the app. 

All you have to do is hit share on the video you're watching and select Ad-free YouTube with AdLock.

We were disappointed that AdLock struggled with some types of ads. For instance, it failed to block the interstitial ad during the Can You Block It test. 

These aren't the results we would expect from a paid product. But otherwise, we were happy with AdLock's performance. 

AdLock paid plan

AdLock offers free browser extensions and paid apps for $1.05-$3.50/mo. The payment options are monthly, yearly, or five years. 

• 1 month/5 devices: $3.50/mo
• 1 year/5 devices: $2.80/mo
• 5 years/5 devices: $1.05/mo

Overall, the yearly and five-year plans have the most value and are definitely worthwhile considering the extra protection you’re receiving.

The free plan can block some ads but not all, and it can't block ads in apps either.

The paid plans promise no forced whitelisting, no tracking, a 30-day money-back guarantee, and 24/7 support. All payment options include the same features and are only different depending on what type of subscription you want.

AdLock only accepts Visa, Mastercard, and PayPal; it has no options for other forms of payment like other credit card issuers and cryptocurrency.

Main features

Like most ad blockers, AdLock has features to block ads and trackers. It also has unique features like filters for languages and social media widgets. 

We'll break down AdLock's features below.

Ad blocker

AdLock’s browser extension gave us an easy view of what ads were blocked on the individual webpage and how many have been blocked overall. 

But unlike other products, AdLock functions only within your system, which means it isn’t outsourcing your requests. You can easily toggle the ad-blocking software off or on depending on the site you’re visiting. 

If you open the app, AdLock will also list out the number of blocked requests and the amount of saved traffic from using the app. For more details, you can click through the Ads reports tab, which breaks down ads blocked by app and domain, or Adblocking statistics, which provide detailed information on blocked commercial content. 

Protection

On the app you'll find the Protection tab, which is where you can keep taps on AdLock's anti-tracking and anti-phishing features. 

AdLock can hide your online presence and personal data from advertisers as well as protect you from phishing, scammers, and malware. All you need to do is turn the toggles on from this tab. 

You can also select Protection statistics for detailed information on blocked trackers, suspicious requests, and intrusion attempts.

Ad filters

If you go to AdLock's settings, you'll find a list of filters for various purposes. There's a spyware filter to help stop websites from tracking your activity, a social media filter to protect your from social media tracking, and annoyances filter to block site elements like online chats and notifications.

AdLock also provides filters for multiple languages to block ads on international websites. 

Unfortunately, the spyware filter and social media filter are only included with the paid tier.

Allowlist

With allowlist, you can distinguish that your favorite creator sites or other sites should run only without an ad blocker. This is also known as whitelisting. 

If you want to make sure your favorite creators get credit for their work, you can easily toggle off the blocker so they receive the ad revenue.

AdLock's test results

A product can tell you all day it’s good, but is it actually? Third-party sites like AdBlock Tester, Cover Your Tracks, and Can You Block It? put those claims to the test.

AdLock scores

Adblock Tester checks a variety of different ways that ads can be displayed to see how your ad blocker performs. AdLock blocked all the ad types that AdBlock Tester threw at it, acheiving a perfect score.

Cover Your Tracks checks tracking ads and your digital fingerprint to see if you’re browsing anonymously. The more unique your fingerprint, the easier it is to connect information from tracking ads to you. 

AdLock was successful at blocking tracking ads and invisible trackers. Our fingerprint was listed as nearly unique, so it wasn't a perfect score, but its better than most ad blockers we've tested.  

Finally, Can You Block It? tests ad blockers against self-hosted ads, including banner ads, interstitial ads, and ad blocker detection warnings. AdLock could only block banner ads and ad blocker detection warnings, though.

The interstitial ad appeared, but AdLock blocked the content of the ad, so it was just a blank page with text. We're glad AdLock blocked the bulk of the ad but were annoyed we still had to deal with it rather than be able to skip it altogether. 

YouTube ad test

AdLock blocked YouTube ads seamlessly and with no lag. We tested this by watching an episode of Chicken Shop Date. 

First, we opened the video with AdLock turned off. We got the usual preroll ads and banner ads lurking in the area. 

Once we turned on the AdLock extension and refreshed the page, the ads were gone. The video never tried to load video ads before or during viewing, and there were no page-loading issues. AdLock even gave us a breakdown of how many ads it blocked on the site.

Just remember that channels run ads specifically to pay the creator for their time and effort. If you have favorite content creators, disabling your ad blocker will allow them to receive revenue from ads. A lot of work goes into content creation, so choosing to see a few ads in return for the value you receive is definitely worth it.

Bypassing paywalls test

We're on the hunt to find an ad blocker that can tackle paywalls. It can be frustrating when an article grabs your attention, only to be blocked from reading it when you click through.

Unfortunately, AdLock doesn't include bypassing paywalls with its arsenal of features. We checked The Wall Street Journal, Bloomberg, and The Atlantic, but all three sites prompted us to sign up for a subscription.

What browser and software is it compatible with?

AdLock has two different types of products. The first is the free version for Chrome, Firefox, and Safari browsers, which block ads when you're using your browser. The second is a paid version for operating systems. The paid version increases privacy across your machine. But don’t sleep on the free browser extension; it’s pretty powerful, proven by our test results.

The ad-blocking apps can be found in the Apple App Store or at the links below.

Browser extensions/add-ons:

• Google Chrome
• Safari
• Mozilla Firefox

Operating system apps:

• Android
• iOS
• Windows
• macOS

AdLock privacy policy

Reviewing the privacy policy for products you use is important to make sure your data isn't shared or sold. We were pleased that AdLock "doesn't sell or share [usage information] with third parties."

It mentions collecting anonymous usage information, like browser language and number of blocked ad requests, but it's not sold or shared with third parties. All AdLock extension users will receive a unique ID that's assigned anonymously upon installation. It'll be stored on AdLock's servers until you uninstall the extension from your device.

The privacy policy also breaks down how your data is used by third parties for analytics, handling payments, hosting and backend infrastructure, and other uses. Although your email may be used for promotional and informational purposes, you do have the option to opt out.

Overall, we liked how easy to read AdLock's privacy policy is and we feel good about its data usage.
