Know before the headline.
Tremor watches public signals around the world. When something starts, it tells you, and counts the minutes until the news catches up.

Eight kinds of public signal.
Any one of them can be noise. Tremor alerts when several move in the same place at the same time.
-
Local posts
Public posts that pile up in one place within minutes.
-
Outage reports
Power, network and service outage maps that anyone can open.
-
Internet measurement
Open measurements of how much of an area is still online.
-
Roads and cameras
Public traffic data and cameras: closures, jams, feeds going dark.
-
Flight tracking
Public aircraft positions: holds, diversions, airspace that empties.
-
Ship tracking
Public vessel positions: ships that stop, turn back or queue.
-
Satellite heat and light
Open satellite passes: new heat points, city lights that go out.
-
Ground sensors
Open sensor networks: ground motion, wind, water level, air quality.
Quiet until something starts.
Pick regions and topics once. Tremor stays silent until enough kinds of source move together there. Then you get one notification, with the sources linked.

It says the signals agree and links them. Checking them is your job.
Four straight answers.
The short version: public data only.
00:01Sources
What does Tremor read?
Public feeds that anyone can open: public posts, outage maps, flight and ship positions, open satellite data, public cameras and sensor networks. Nothing that needs a login.
00:02Privacy
Can it see anything private?
No. It has no access to private accounts, closed groups, direct messages or leaked data, and it does not try to get any. If a source is not open to everyone, Tremor does not read it.
00:03Storage
Where do my alerts go?
They stay on your PC. The watchlist and the alert history are stored locally. An alert goes to a Windows notification and, if you switch it on, to your own email.
00:04Rules
Is this allowed?
Reading public information is what anyone can do by hand. Tremor does it around the clock. Follow each source’s terms and your local law, and do not use it to harass anyone.
Catch the next one early.
For newsrooms, security teams, investigators and due-diligence desks.
