Cisdem AppCrypt is a website blocker and app lock rolled into one. When working as a porn blocker for Windows, it stands out for being easy to use and effective and can offer the following features.
1. Download and install AppCrypt on a Windows computer.
Free Download Windows 11/10/8/7
2. When you open it for the first time, set a password.
To prevent your own access to porn, it's recommended that you ask someone else, such as a family member, to set the password for you.
3. Click the AppCrypt icon on the taskbar. Alternatively, right-click this icon and then choose Open Main Window.
4. Enter the password to access the main window of this porn blocker.
5. Click the Web Block tab and install the extension on the browser(s) of your choice.
There's an extra step. Here I use Chrome as an example. Go to chrome://extensions/, find this extension, click Details, and then turn on Allow in Incognito.
6. In the extension, select the Block Porn checkbox. This will automatically block all porn sites.
Alternatively, you can decide which porn websites to block yourself. In the Web Block tab, do any or all of the following things.
7. If some apps on the computer contain adult content, you can add them to the block list under the App Lock tab.
Note: Unlike some Windows porn blockers, AppCrypt works with both administrator accounts (typically used by adults) and standard accounts (often used by children). This makes it usable for preventing porn access on computers for people of all ages.
There are several ways to permanently or temporarily unblock an item on the block list, such as removing the item from the block list or quitting AppCrypt. But any of the ways requires the password. In addition, if one attempts to unblock a porn site by turning off or uninstalling the extension, AppCrypt will immediately lock that browser with a password. This makes the blocking hard to bypass, ensuring the tool’s effectiveness.
