 TikTok is, for most children, the first social network they want and the last one parents feel confident about. That instinct is not misplaced. In 2026, the answer to "is TikTok safe for my child?" is: **it depends on your child's age, what you are willing to set up, and how much you are prepared to talk to them about what they see**.

 - **Our category layer** — on top of the ad/tracker baseline, the Child profile adds social media (including TikTok), adult, gambling, dating, and gaming categories, and enforces safe search on Google, Bing and DuckDuckGo.
 
 We trim the raw upstream lists from around 119,000 domains down to roughly 15-30,000, because a smaller, curated list is faster on mobile, uses less memory, and produces fewer accidental blocks on regional German and European sites. This trimming is the work that matters — the raw lists are public, the curation is the product.

 Online safety is not a switch. It is a stack of seven layers, each covering something the others don't. When parents struggle, it is almost always because they have set up one or two layers and assumed that was enough. It never is.

 There is no single "parental control" that works. Every family eventually learns this the same way — they set up Screen Time on an iPad, watch their ten-year-old bypass it in an afternoon, and start searching for a better answer. The better answer is not a different product. It is a layered setup that plays each tool to its strengths.

 - **Router filtering only.** Protects the house, fails the moment they're on mobile data or friends' Wi-Fi.
 - **VPN only.** Doesn't limit time spent in the apps that *are* allowed. You still need device-level limits.

 "My child just wants to play Roblox with her friends. It's rated 7+. What's the fuss?" Every child safeguarding lead hears this sentence weekly, and the answer is that age ratings measure the wrong thing. PEGI and ESRB rate *the mechanics* — cartoon violence, in-game purchases, user-generated content. They do not rate **who your child is going to talk to** while they play. That is where the actual risk sits.

 For younger children, device-level DNS filtering is the one control that doesn't depend on them having the correct age on their account, not having a second account, or not installing a different app. When `roblox.com`, `fortnite.com` or `discord.com` do not resolve, the app and the website both fail to load.
 
 The Agiliton VPN Child profile blocks the **gaming** and **social media** categories by default, which covers all three of these platforms. Our curated blocklist — built from HaGeZi Multi, OISD, and a Cloudflare top-10k safety allowlist, trimmed to around 15-30k domains optimised for German traffic — adds the specific platform domains on top of the baseline ad/tracker filter.
