Part 1. How to block porn on Chrome on Mac & Windows PC
There are two types of porn blocker for Chrome on computers: apps and browser extensions. In this part, I will discuss both and show you how to set them up.
1. Use Cisdem AppCrypt (app)
Compatibility: Mac, Windows
If you are looking for an effective tool to prevent yourself or a loved one (such as your spouse or children) from accessing porn, Cisdem AppCrypt can be the best choice. It's easy to set up, feature-rich, and difficult to bypass due to password protection and other measures.
As a porn blocker for Chrome, it offers the following:
- Restrict websites by category, such as Porn
- Block specific adult sites added by you
- Filter URLs by keyword, such as "porn", "adult", and "nude"
- Block specific search terms on search engines, YouTube, and social media, such as "sexy"
- Allow you to create a completely porn-free environment by restricting all sites except allowed ones
- Apply blocking to Chrome along with other browsers in both normal and incognito browsing
- Protect blocking with a password
Here's how to set up this tool.
1. Download and install AppCrypt on your or a family member's Mac or Windows computer.
Free Download macOS 10.12 or later
Free Download Windows 10 or later
2. When you open this tool for the first time, set a password.

3. On a Mac, click the AppCrypt icon in the menu bar, then choose Open Main Window. On a Windows PC, simply click this icon on the taskbar.

4. Enter the password to access the tool's main window.

5. In the Web Block tab of the main window, do one or more of the following as needed:

- Click the Import dropdown menu, then choose the Porn Sites option. This will automatically add all popular adult sites to the block list.
- Add a specific porn site in the URL field, then click Add.
- Add specific porn-related keywords. Any URL containing a blocked keyword will be automatically detected and blocked.
- In the Import dropdown menu, choose the TXT file option to import your own list of porn sites to block.
The blocking is permanent as long as AppCrypt is running. Since a password is required to quit or uninstall this porn blocker, change its settings, or do other kinds of bypassing, it's difficult to get around the blocking.

| Keyword | Number of websites with this keyword |
|---|---|
| porn | 1,324 |
| sex | 1,064 |
| xx | 577 |
| webcam | 384 |
| tumblr | 324 |
| adult | 219 |
| amateur | 188 |
| nude | 170 |
| mature | 135 |
| hentai | 104 |
2. Use BlockerX (extension)
Compatibility: Mac, Windows
There are extensions specially designed to block porn on Chrome. BlockerX is one of the most popular options, with a 4.5-star rating on the Chrome Web Store. After testing, I found it is effective in blocking porn sites for self-control. But I don’t recommend it for parental controls, as extensions can be easily bypassed.
This porn blocker Chrome extension can do the following things.
- Block tons of adult websites with one click.
- Let you add specific adult sites to the block list (limited to 1 site in the free version).
- Let you block websites by keyword (limited to 1 keyword in the free version).
- Automatically turn on Safe Search to filter adult content.
- Allow you to block Incognito mode in Chrome.
Below are the steps.
1. Open your Chrome browser. Go to the Chrome Web Store.
2. Search for BlockerX. Click Add to Chrome > Add extension.

3. Wait for the download to complete. Click Get Started. Select your situation, such as “I want to get rid of my porn addiction”. Click Continue.

Select additional details, such as how often you watch porn and what triggers it.
Click I am in.
4. Sign in with your Google account.
5. Enable Block Adult Content in the upper left corner.

3. Use Porn Blocker (extension)
Compatibility: Mac, Windows
I searched for “block porn” in the Chrome Web Store and found this porn blocker extension - Porn Blocker by Relay Health Inc, which is ranked first. I tested it on my computer and found it very easy to use. Highly recommended for users who are trying to quit porn.
It can do the following things.
- Automatically block most popular porn sites (although a few newer porn sites may still be accessible).
- Redirect you to a different site when you try to visit a porn site.
- Provide free resources such as PDF guide, top-rated podcast to help you quit porn addiction.
Below are the steps.
1. Search for Porn Blocker in the Chrome Web Store. Select the first one from the result list.
2. Click Add to Chrome > Add extension to install it.

Then most adult websites will be blocked in Chrome. It’s very easy to setup.

Quick facts
I’d also like to share a few quick facts that you may find useful.
- Mac’s Screen Time does help users limit access to adult websites. But it doesn’t support non-Safari browsers like Chrome.
- It’s possible to block specific adults websites on Chrome by editing the hosts file on a Mac or PC. But it isn’t efficient at all and not easy to use.
- If your router has parental controls or something similar that allows you to block web content, you can set your router to block porn-related content on certain or all devices (like a computer or phone) connected to its network. Find the detailed information on how to set on the router manufacturer’s website.
Part 2. How to block adult websites on Chrome on Android
I tested three popular porn blocker apps in the Google Play Store and picked Cisdem AppCrypt. It is compatible with Android 8.0 and up. It can do the following things.
- One tap to block adult sites
- Let you add specific adult sites to the block list
- Support Chrome, Chrome, Samsung Internet, Opera, and other popular browsers
- Provide password protection
Below are the steps.
1. Install AppCrypt on your device.
2. When you launch it for the first time, set a PIN or pattern.

3. In the Web Block tab, type the domain name of the adult site that you want to block and then tap Add. Repeat this step to block other adult sites.

4. In the same tab, add certain keywords (such as porn, adult, or xxx) to the block list. This will automatically block all URLs that include any of these keywords.
Because of the PIN or pattern you set, the blocking is not easy to bypass.
Quick facts
- Some other popular Android porn blockers that support Chrome are BlockerX, BlockP and Pure Web.
- The four apps mentioned in this part are designed to help adults block access to porn. If you are a parent who is looking for a way to block inappropriate sites on Chrome on your child’s Android device, you can use Google Family Link.
- Chrome extensions only work with the Chrome app on a computer (like a desktop or laptop). They don’t support the Chrome mobile app. So the two porn blocker extensions mentioned in the first part don’t work on Android.
Part 3. How to block adult websites on Chrome on iPhone
Built into Apple devices, Screen Time is a set of settings that can be used for restricting web content. As mentioned, Screen Time on Mac doesn't support Chrome. The good news is that Screen Time on iPhone actually works with Chrome along with other web browsers.
- Provide an option to block almost all adult sites
- Block specific sites added by you
- Protect the blocking with a PIN
1. Open the Settings app an iPhone.
2. Tap Screen Time.

3. Tap Turn On Screen Time.
4. Tap This is My iPhone or This is My Child's iPhone when asked.
5. Tap Use Screen Time Passcode and set a passcode.
6. Tap Content & Privacy Restrictions, then turn it on. Enter the passcode when prompted.

7. Select Content Restrictions > Web Content.
8. Select Limit Adult Websites.

From now on, websites that Apple considers adult and explicit will be blocked on Chrome.
Quick facts
- Cisdem AppCrypt is also available for iPhone. It can filter most porn sites and support Chrome as well as other browsers. You can get it from the App Store.
- You can block explicit content like pornography from appearing in Google search results using Google SafeSearch feature. To enable SafeSearch on Google app on phone, click the profile photo on the upper right corner. Click Settings. Scroll down to find the SafeSearch option. Turn it on.
