Lunio alerts your emergency contacts if you miss a daily check-in — no GPS, no location data, no surveillance. Safety through trust, not tracking.
Most personal safety apps work by broadcasting your GPS coordinates — to a server, to an emergency service, or to your contacts directly. Lunio works differently. You set a daily check-in interval and tap once when you're fine. If you miss the window, your emergency contacts are automatically notified by email or SMS. Your location is never involved. Not requested, not collected, not stored.
This is called a check-in model. The alert is triggered by silence — a missed check-in — not by coordinates on a map. It provides the same essential outcome (your people know something is wrong) without the privacy trade-offs that come with continuous location sharing.
52% of people don't feel safe using location-tracking apps. Here's why that concern is well-founded — and what Lunio does instead.
Continuous GPS data reveals your daily patterns — where you sleep, work, and spend time. That information is dangerous in the wrong hands, even when shared with good intentions.
Live location sharing is frequently used as a tool for control in unhealthy relationships — framed as "care" but functioning as surveillance. An app that never holds your location can't be weaponised this way.
Many free safety apps monetise by selling location data to brokers. That data is aggregated, profiled, and resold — often to advertisers, insurers, or parties you've never consented to.
Location data stored by apps can be accessed by law enforcement, subpoenaed in legal proceedings, or exposed in data breaches — without your knowledge or consent.
Lunio eliminates these risks at the source: by never collecting location data in the first place, there is nothing to expose, sell, or misuse.
The check-in model is simple: silence triggers the alarm, not your location.
Choose daily, every 48 or 72 hours. Add trusted contacts — they confirm once before they can receive any alerts.
That's the entire check-in. Lunio records the timestamp, resets your next due window, and nothing else is transmitted.
If you miss your window, contacts receive an email — followed by SMS on paid plans. No location shared. Just the fact that you didn't check in.
Privacy isn't a setting in Lunio — it's the default. Here's exactly what is and isn't collected.
Lunio never requests location permissions. It doesn't know where you are, and it never tries to find out. No GPS, no cell tower data, no IP geolocation stored.
Lunio has no advertising SDK and collects no behavioural data. There is no profile built from your usage, and nothing is sold to third parties.
Lunio is not a health or wellness app and collects no health metrics, biometrics, or device sensor data.
Data is stored on Google Firebase servers in Belgium. Lunio is operated by a German company and subject to EU data protection law. Read our Privacy Policy.
No one is added to your contact list without confirming their invitation. They can unsubscribe at any time from any notification they receive.
