Important Note!
To block exact keyword matches and avoid over-blocking, add underscores around the word.
  • Example: Adding _bra_ blocks only “bra”.
  • Without underscores bra, the program will also block any word containing that sequence: brand, bravo, brake, zebra, etc.

In addition to full blocking, HT Parental Controls allows you to set time limits for websites that contain specific keywords in their URL or title.

  1. Go to Rules → Website Limits.
