Salvus
Speeding vehicle nearby
Driver warned in real time
Crash black-spot ahead
Offline safety warning
Anonymous by design.
Salvus aims to warn you in real time about dangerously speeding vehicles and crash black-spots nearby — no names, no plates, no sign-up.
Why Salvus exists
Every year, Bulgaria's roads take hundreds of lives.
This map is real: every point marks a place where someone died in a traffic crash. Salvus was built to give drivers a timely warning as they approach dangers like these.

How it works
A warning before the danger reaches you.
Salvus turns every driver into an anonymous sensor. When someone speeds dangerously, everyone nearby gets a heads-up.
- 1
Drive normally
Salvus runs quietly in the background and shares only your anonymous position and speed — never your identity.
- 2
Danger is detected
When a vehicle moves dangerously fast for the road, Salvus spots it in real time across the network.
- 3
Nearby drivers are warned
Everyone close by gets an anonymous alert — “a vehicle is moving too fast near you.”
Privacy by design
Anonymous to other drivers.
Safety should never cost your privacy. Your identity is never shown to other drivers — Salvus uses only your position and speed, kept briefly, to deliver alerts.
No names, no plates
Alerts never identify the speeding vehicle or its driver. Just “too fast, nearby.”
No sign-up
No account, no email, or phone number needed to use Salvus. On our network you're just an anonymous app ID.
Kept only briefly
Only your latest position is stored, and it's cleared within about 10 minutes of you stopping.
Encrypted on device
Sensitive app data is sealed in your phone's hardware-backed secure storage.
Works even when no one's around
Built-in crash black-spot warnings.
Salvus also warns you as you approach historically dangerous crash sites — fully offline, with no other drivers needed.
Real crash data
Hundreds of fatal-crash zones from official Bulgarian road-safety records, bundled right into the app.
No signal required
Black-spot warnings run entirely on your device — even with no connection and no one else nearby.
A timely heads-up
When you're heading toward a known danger zone, Salvus gives you a calm, early warning.
Free for everyone
Free is the whole app. Pro is the fast lane.
Every safety feature works free, forever — the alerts, the crash-zone warnings, all of it. When a country gets busy, free sessions wait briefly in a queue; Pro skips it, lets you set how often you're alerted and how often crash-zone warnings repeat, and puts every alert you've sent and received on your own map. €49.99/year (≈ €4.16/month) or €6.49/month, and the first 7 days are free.
Common questions
The things drivers ask before installing.
Short answers to the four questions we get most.
Does Salvus drain my battery?
Salvus uses your phone's built-in background location service and sends a small position update every few seconds — but only while a driving session is running. There is no map to render, no video and no screen time. End the session and it stops completely.
Is Salvus a radar or speed-camera detector?
No. Salvus never shows police, speed cameras or checkpoints, and holds no data about them. It compares how fast vehicles are moving with the speed limit of the road they are on, and it knows where crashes have happened in the past. It is a road-safety warning, not a tool for avoiding enforcement.
Do you see my location? Can anyone identify me?
No one can identify you from an alert — it says only that a vehicle is moving too fast nearby, never who, and never which car. No name, email or plate number is attached to you: on our network you are an anonymous app ID. We keep only your latest position, and it is cleared within about 10 minutes of you stopping.
Read the privacy policyDoes it work with no mobile signal?
Black-spot warnings do — they run entirely on your device, with no connection needed. Live alerts about nearby speeding vehicles need a data connection, because they are delivered across the network the moment they happen.
