Discover who's around you
CampuSiren finds people nearby using Bluetooth — no GPS tracking, no location data. Ever. Discover, ping anonymously, and chat when both of you are ready.
A warm signal on campus
Not a scanner.
How it works
Three steps to connect
No profile creation marathons. No swiping through hundreds of strangers across the country. Just real people who are actually near you.
- STEP 01
Open & Discover
Open CampuSiren and see floating bubbles — each one is a real person within 50 meters of you. Works in cafés, campuses, events, parks — anywhere people gather.
- STEP 02
Ping Anonymously
Tap a bubble to send an anonymous ping. They'll know someone nearby is interested, but not who — until they choose to connect.
- STEP 03
Match & Chat
If they ping you back, you match! Start chatting instantly. Your identity stays hidden until you're both ready.
Privacy
Your privacy is not a feature.
It's the foundation.
No GPS Tracking
Proximity is detected using short-range Bluetooth and Wi-Fi Direct signals. No coordinates are ever sent to our servers.
Anonymous Until You Choose
Your identity is hidden behind an avatar. You control when and to whom you reveal yourself.
Delete Everything, Instantly
Your account, messages, photos, and all data can be permanently deleted in one tap from Settings. Irreversible. No data retained.
Block & Report
Instantly block anyone to prevent all contact. Report inappropriate behavior — our team reviews every report.
