Salvus

About this app

Salvus is an anonymous safety network for drivers. It aims to warn you in
real time about dangerously speeding vehicles, crash black-spots and hazards
other drivers just passed — before they reach you.

HOW IT WORKS
Start a session and Salvus runs quietly in the background, sharing only your
anonymous position and speed. When a vehicle nearby moves dangerously fast
for the road, drivers in its path get a heads-up. Alerts never identify the
vehicle or its driver — just "too fast, nearby."

WARNINGS YOU CAN HEAR
Salvus warns you out loud, so you can keep your eyes on the road. Pick a
sound, a spoken warning or silence — separately for each kind of warning.
Speed alerts reach you during a session even if you never allowed
notifications.

CRASH BLACK-SPOTS, EVEN OFFLINE
Salvus also warns you as you approach historically dangerous crash sites,
drawn from hundreds of fatal-crash zones in official Bulgarian road-safety
records and bundled into the app. These warnings run entirely on your device
— no connection and no other drivers needed. See them around you on the map.

SLOW-DOWN ZONES
Tap the hazard button when you pass something drivers behind you should know
about — a crash, debris, standing traffic. A zone goes live once a second
driver marks the same spot, warns everyone approaching it, and clears itself
within the hour. Reporting, warnings and the live map are free for everyone.

ANONYMOUS BY DESIGN
• No account, email or phone number needed
• Alerts carry no names and no plates
• Hazard reports are anonymous, with no way to trace who marked a spot
• Only your latest position is stored, cleared within about 10 minutes of
you stopping
• Sensitive app data is sealed in your phone's hardware-backed secure storage

SALVUS PRO
Every safety feature is free, forever. When a country gets busy, free
sessions wait briefly in a queue; Pro skips it, lets you choose how often
each kind of warning repeats, and puts every alert you've sent and received
on your own map. Salvus Pro is €6.49 per month or €49.99 per year, with a
7-day free trial.

IMPORTANT
Salvus is a best-effort assistant, not a substitute for careful and lawful
driving. It cannot detect every vehicle or every danger, and warnings may be
late, incomplete or inaccurate. Always drive to the conditions and obey the
law. Never interact with your phone while driving.
