For teenagers going out at night, solo trips, first dates with strangers, and anywhere you want someone watching out for you.
Set a check-in timer before you head out. Miss it, and Defcon5 quietly escalates on its own — the people you trust find out, without you having to make a call or send a text at the worst possible moment.
A missed text gets explained away. With a safety app built around check-ins, a missed one triggers something automatically — nobody has to notice, or worry, or wonder.
Your teenager sets a check-in timer before going out at night. You get real peace of mind without calling every hour — and a real alert, automatically, if something's wrong.
Meeting a stranger, walking through an unfamiliar area, a first date from an app — set a timer for when you expect to be done, and a guardian is already watching without having to ask.
No signal doesn't mean no protection — Defcon5 already knows your last known position by the time anyone needs it.
A daily check-in habit means a missed one gets noticed the same day — not days later.
No accounts to configure for the people watching over you — they just get a username and a code.
Choose how often Defcon5 checks on you. Miss one and the level drops on its own — nobody has to notice for you.
You invite someone by name. They confirm with a share code. Nobody can link to you silently, ever — not even with the code alone.
Save a safe-arrival position. Get back to it and the session ends on its own — that's the only way it ends, by design.
If someone is standing over you, forcing you to check in, you don't reach for your real code. You use the other one.
Your screen shows exactly what a normal check-in looks like. Nothing about it gives anything away.
What is Defcon5?
A safety app that works by check-in instead of by panic button. Miss a scheduled check-in and it escalates on its own through five alert levels, notifying the guardians you've invited.
Who is it for?
Teenagers going out at night and their parents, solo travelers, first dates with strangers, anyone entering an unfamiliar area, lone workers — anyone who wants someone to notice automatically if something's wrong.
Does it track my location all the time?
No. Location is only collected during an active alert (Defcon 3, 2, or 1), and only if you've turned it on. At a safe level, nothing is tracked.
How does a session end?
By physically arriving at a safe-arrival position you set in advance — that's the only way, aside from a parent PIN override in Parent Mode.
No name, email, or phone number is required to create an account — just a username.
Your location is invisible to us at a safe level. It's only ever collected during an active alert, and only if you turned it on.
We don't sell data, run ads, or share anything with anyone besides the guardians you've explicitly invited.
Everything is deleted on a schedule — location trails 48 hours after an alert ends, whether anyone asks or not.
