Hello chimzera, the simplest and most dependable way is to use your phone’s built-in parental controls. Go to Settings > Digital Wellbeing & Parental Controls. Set up a child account or use the app timer to block TikTok permanently. Alternatively, install a reputable third-party app blocker with password protection. Avoid just uninstalling TikTok, as it can be reinstalled easily. Keep the password to yourself, so the block really sticks. Simple steps, steady results.
