Anonymous, location-verified campus discussions — powered by trust, not followers.
================================================================
Jump straight in — no setup, no installs. Works on any modern browser (desktop & mobile).
- Open the link → You'll land on the login/register page
- Register a new account → Pick any username & password (no email needed)
- Select your campus → Choose "Manipal University Jaipur" or any listed campus
- Allow location access → The app will verify your GPS position
- Explore! → Browse the feed, vote on posts, check the jury system
Temporary hackathon workaround — these options will be removed in production.
Since GPS verification is required and you may not be at a supported campus, here's how to still access everything:
| Method | Steps |
|---|---|
| Test Account | Username: testuser · Password: test1234 |
| New Account | Register normally — the hackathon build has relaxed GPS checks so evaluators outside campus can still get full access |
| Demo Mode | Append ?demo=true to the Feed URL to inject live visual simulations of the 3-Tier AI moderation pipeline directly into the feed. |
Proximity is an anonymous, real-time campus discussion platform where your physical presence on campus earns you the right to speak. No emails, no phone numbers, no usernames tied to your identity — just GPS-verified trust.
Think of it as the campus bulletin board reimagined for the digital age: a space where students can share thoughts, confessions, questions, and events — completely anonymously — while a multi-layered moderation system keeps the community healthy.
| Problem | Proximity's Answer |
|---|---|
| Trolls flood anonymous platforms | Trust Tiers — newcomers earn participation over time through verified check-ins |
| Harassment goes unchecked | 3-Tier AI Moderation — keyword filters → ML toxicity scoring → LLM contextual analysis |
| Moderation is opaque & biased | Jury System — community members vote blindly on flagged content |
| Fake accounts from off-campus | GPS Geofencing — only verified campus residents gain full access |
| Privilege never expires | Trust Decay — stop showing up, lose your voice |
Tiered access based on campus presence:
| Geofenced polygons validate campus attendance using the Ray Casting algorithm — no third-party location APIs, fully self-contained. |
Flagged posts go to a blind jury of verified campus members. 3 votes, majority wins. No single person decides what stays or goes. |
|
Nested reply chains with voting, color-coded depth indicators, and GIF support via Tenor. | Create polls, browse campus events, search across all posts — all anonymous, all verified. |
Proximity uses GPS polygon geofencing to verify that users are physically present on campus before granting participation rights.
📍 User checks in → Ray Casting Algorithm → ✅ Inside polygon · Check-in recorded / ❌ Outside · Denied
| Rule | Detail |
|---|---|
| Check-in cooldown | Max 1 check-in per 4 hours |
| GPS accuracy | Must be < 500m |
| Campus zones | Each campus is a unique polygon |
| Campus | Location | Status |
|---|---|---|
| Manipal University Jaipur (MUJ) | Jaipur, Rajasthan, India | ✅ Live |
Proximity is built to scale. Adding a new campus is as simple as defining a polygon of GPS coordinates — no code changes needed, just configuration. We plan to onboard more universities and colleges in the near future. If you'd like your campus added, reach out to us!
