Privacy-first personal safety

Personal safety without location tracking

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.

Why location tracking carries real risks

Safety apps shouldn't create new dangers

52% of people don't feel safe using location-tracking apps. Here's why that concern is well-founded — and what Lunio does instead.

Routine exposure

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.

Coercion and control

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.

Data broker sales

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.

Third-party data access

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.

How it works

Safety through check-ins, not coordinates

The check-in model is simple: silence triggers the alarm, not your location.

Set your interval

Choose daily, every 48 or 72 hours. Add trusted contacts — they confirm once before they can receive any alerts.

One tap when you're fine

That's the entire check-in. Lunio records the timestamp, resets your next due window, and nothing else is transmitted.

Silence triggers the alert

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 by design

What Lunio never collects

Privacy isn't a setting in Lunio — it's the default. Here's exactly what is and isn't collected.

No location data — ever

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.

No advertising profiles

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.

No health data

Lunio is not a health or wellness app and collects no health metrics, biometrics, or device sensor data.

GDPR compliant, EU-hosted

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.

Contacts must consent

No one is added to your contact list without confirming their invitation. They can unsubscribe at any time from any notification they receive.

Delete everything, any time

Go to Settings → Delete Account. All your data — check-in history, contacts, everything — is permanently and immediately deleted from our servers.

Common questions

About privacy and safety without tracking

How do safety apps without GPS tracking work?
Instead of broadcasting your location, a check-in app asks you to confirm you're okay at set intervals. If you miss the window, your emergency contacts are automatically notified. Your location is never involved — the alert is triggered by silence, not by coordinates. Lunio uses this model: one tap per day to confirm you're fine, automatic alerts if you don't.
Can you alert emergency contacts without sharing your location?
Yes. Lunio does exactly this. You set a daily check-in interval, confirm you're okay with one tap, and if you miss the window, your contacts receive an email or SMS alert. No location data is shared, collected, or stored at any point.
What apps don't track your location?
Most personal safety apps use GPS as a core feature. Lunio is an exception — it is a check-in app that never requests or stores location data. Other non-GPS options include Kitestring (text-based check-ins) and basic timer-and-call setups with a trusted person. Lunio offers the most automated version of this with built-in email and SMS escalation.
Why should I avoid location-sharing safety apps?
Location-sharing apps carry several real risks: GPS data can be sold to data brokers or accessed by third parties; continuous sharing reveals daily routines that can enable stalking; and live location can be used as a tool for control in unhealthy relationships. A check-in app like Lunio provides the same core safety outcome — alerting contacts when something is wrong — without creating these risks.
Is Lunio actually private — what data does it collect?
Lunio collects only what is needed to run the service: your account credentials, check-in schedule, and your contacts' email addresses. No location data, no health data, no advertising profiles. Data is stored on EU servers in Belgium under GDPR. We do not sell data to third parties. Full details in our Privacy Policy.
Does Lunio work without giving it location permissions?
Yes. Lunio never requests location permissions. The only permissions it needs are push notifications (for check-in reminders) and internet access (to sync your signal). No location permission is ever asked for.
