Each of these apps has a Family Center. Each is genuinely useful. Each is meaningfully underused by parents. Takes about 25 minutes to set up all three.
On your Snap: Profile → ⚙️ Family Center → Invite. Your teen accepts. You now see who they're messaging (not the contents) and can flag issues to Snap.
Teen's Profile → ⚙️ → See Me in Quick Add → Off. Snap Map → Ghost Mode → On. These two changes dramatically limit contact from strangers.
Snap's built-in AI chatbot is pinned at the top of chats. You can't fully remove it without Snap+, but you can choose not to use it. Have a conversation about why.
TikTok Settings → Family Pairing → Parent. Scan your teen's QR code. Now you control Screen Time Limit, Restricted Mode, Direct Messages, and Discoverability from your own phone.
Family Pairing → Direct Messages → No one (under-16) or Friends (16+). Comments → Friends.
Family Pairing → Daily Screen Time → 60 min (or your number). Kids can request more via you.
Your IG: Settings → Supervision → Set Up. Your teen accepts. Now you see who they follow, their weekly time, and can set daily limits.
Teen account (under-16): Settings → Privacy → Private Account → On. Messages → Message requests → From no one for unknowns.
Reduces algorithmic pull toward stranger accounts. Instagram: Settings → Content → Suggested posts → Off. TikTok: For You tab → long-press → "Not Interested" is the real control. Snap: Discover → Hide this channel.
Open the Family Center together once a week. "Anyone new?" "Any messages that felt weird?" Five minutes. Builds the habit without it feeling like surveillance.
