22:15Privacy and fairness
What we never do, at any hour.
Everyone is home and the map has gone quiet. What follows holds for the person on that map, tonight and every night: they always see who is looking, they choose how precisely they’re seen, and they can step away without asking anyone.

01The mirrorFree
You always see who is looking at you.
A live “looking now” eye on your own pin, and a ledger of who found you, set alerts on you or checked your speed.
Your mirror · today
- Dad is looking at your location right nownow
- Mum found you at the mallShe asked first. The search began only after you agreed.
- Mum checked your speedIt landed here as it happened.
- Dad set an arrive alert on you · SchoolIt came to you as a card, approved once.
02The sharing ladderFree
You choose how precisely they see you.
Per group, one of four steps: Exact, Neighbourhood, City or Paused. Each step can be time-boxed, and it shows on your avatar, so nobody is left guessing.
What the Family group sees
Exact
Your dot, with its accuracy ring, and the place name: Home.
For how long?
Exact is the everyday step. Pick another step to put a time on it.
03Pause and leaveFree
Pause is quiet. Stopping everything sends nothing.
For adults, pause is a calm, visible state: no push goes to the family. And when you need to step away from everyone at once, there is one exit, “Stop sharing now”, and it sends nothing at all.
Nothing. Pausing sends no notification.
Stop sharing now.
One quiet exit, with a quick-exit button. It sends nothing.
Leaving a group never needs anyone’s approval.
04Your data
Never sold. No ads. No insurers.
No ads, ever — the subscription is the business.
No analytics or ad code in the app.
Your circle’s locations travel encrypted through our server and are not sent to any other company. The map itself is drawn by Apple Maps on iPhone and Google Maps on Android, so Apple or Google receives the map area you are looking at.
Your history lives on your phone.
7 days on Free, 30 days with Plus — on your phone, not on our server.
Your places are checked on your phone.
Arrive and leave alerts are worked out on the phone itself, not on our server.
Delete your account, any time.
It is deleted from our live server at once, and our encrypted backups age out within 15 days. What your family’s phones already received stays on their phones.
05What our server sees
Don’t take our word for it. The app shows you what our server sees.
A screen in the app shows you exactly what our relay receives for a location update: who it’s from, when it arrived, how many people it’s for, its size, and the location itself as an opaque envelope.

What our relay can see about it: who it’s from, when it arrived, how many people it’s for, and its size.
The location itself, as an opaque envelope. This is what our server stores for it.
Redrawn from the app’s “What our server holds” screen. The values are an example.
Why the careful words about encryption?
We’ll only use the words “end-to-end encrypted” after an outside security review. Until then, the app shows you exactly what our server receives.
06Never built
Things TZX Locate will never build.
Not on any plan, not as a hidden setting, not later.
- No stealth or hidden tracking
- No fake or frozen location
- No remote listening
- No uninstall blocking
- No monitoring of one adult by another
- No ads or data partnerships
- No public profiles or friend leaderboards
- No face recognition
Can I use it to watch another adult?
No.
TZX Locate has no adult-over-adult monitoring, and never will: not of a spouse, a driver, a nanny or a maid. Every adult on the map sees who is looking, chooses how precisely they’re seen, can pause quietly, and can leave any group without anyone’s approval.
