A glossary of campus social app terms

Campus social apps come with their own vocabulary, and a lot of it gets used loosely. This glossary defines the terms in plain English, with notes on how each one works in practice. Where it's relevant, we've added how Tide approaches it, since Tide is built around meeting real people rather than anonymous gossip.

.edu verification

Confirming someone is a real, enrolled student by checking their college email address (the part ending in .edu) before they can use an app. Some apps verify with a one-time code sent to that email; others let you sign in directly through your school's Google or Microsoft account. The point is to keep the space students-only — no bots, no random strangers, no adults pretending to be undergrads. On Tide, every account is .edu-verified, which is the difference between a campus feed and the open internet. More on how we handle it on the trust page.

Students-only

An app where the only people who can get in are verified students, usually gated behind .edu verification. It's a design choice, not just a tagline: when everyone in the room is a student at a real college, the conversation, safety, and trust all change. This is the core idea behind Tide and the reason it feels different from a public app where anyone can register.

Anonymous feed

A shared stream of posts where authors' names aren't shown. Anonymity can make it easier to ask an awkward question, vent, or share something vulnerable without it being attached to you forever. The downside is that full anonymity also lowers the bar for rumors, harassment, and pile-ons, because there's little accountability. Tide has an optionally anonymous campus feed — you choose post by post whether your name shows — so you get the freedom without making anonymity the default mode. We dug into the trade-offs in are anonymous campus apps safe.

Pseudonymous

Posting under a consistent username or handle that isn't your legal name. It sits between full anonymity and real identity: people can't necessarily tell who you are off-platform, but your posts are tied to one persistent identity, so there's still some accountability and you can build a reputation. A handle like "saltyotter" is pseudonymous; "Anonymous" is not.

Daily match

A feature that suggests one new person to you each day, usually based on shared interests, classes, or campus. The "one per day" cap is intentional — it nudges you to actually message that single person instead of endlessly swiping and never reaching out. Tide's Daily Tide shows you one interest-matched student from your campus per day. It's the opposite of an infinite feed: small, low-pressure, and built to turn into a real conversation.

Friend code

A short code (Tide uses 5 digits) that you share with someone so they can add you directly, instead of searching your name or scanning a profile. It's handy when you meet someone in person — in a lecture, at a club, in line for coffee — and want to connect without exchanging phone numbers. They type your code, you're connected. Simple, and it keeps your contact info private until you decide otherwise.

Hyperlocal

Content and connections limited to a very specific place — in this case, your single campus. A hyperlocal feed shows you posts from people at your school, not a national firehose, so an event, a lost-and-found post, or a "anyone in ECON 1 want to study?" message actually reaches the people it's for. Campus events, class chats, and the daily match are all hyperlocal by design. You can see which schools are live on the campuses page.

Karma

A running score tied to your account that goes up when other people upvote or react positively to your posts and comments. On some apps karma unlocks features or signals that someone is a trusted, active member. It can encourage good contributions, but chasing karma can also push people toward whatever gets the most reactions rather than what's actually useful. Tide deliberately leans on real connection and meeting people over a points game.

Doxxing

Publishing someone's private information — full name, dorm, class schedule, phone number, photos — without their consent, usually to harass or intimidate them. It's one of the real dangers of anonymous campus apps, because anonymity protects the person doing it while exposing the target. Doxxing is against the rules on any responsible platform and is a removable, often reportable offense. Tide's optional-identity design and active moderation are meant to make it harder to do and faster to deal with.

Moderation

The people, rules, and tools that keep a community safe — reviewing reports, removing posts that break the rules, and acting on harassment, threats, or doxxing. Good moderation is a mix of clear guidelines, user reporting, and a team that actually responds. It's the unglamorous backbone of any app where strangers talk to each other. Combined with .edu verification, it's how a campus app stays a place you'd actually want your friends to be.

Why the words matter

Most of these terms describe a trade-off between openness and safety. A fully anonymous, ungated feed is open but easy to abuse. A students-only, verified, moderated app gives up some of that anonymity in exchange for a place where the person on the other end is a real classmate. Loneliness on big campuses is a documented problem, and the tools you use to meet people shape how that goes.

Tide's bet is that you make more real friends when identity is optional but real, the people are verified students, and the app points you at one person a day instead of an endless scroll. If that sounds like what you're after, you can open the web app or grab the iOS beta on TestFlight. Still have questions? The FAQ covers the rest.

Frequently asked questions

What does .edu verification mean on a campus app?

It means the app confirms you're a real, enrolled student by checking your college email (the address ending in .edu) before letting you in. Some apps send a one-time code to that email; others let you sign in through your school's Google or Microsoft account. The goal is to keep the app students-only, with no bots or random strangers.

What's the difference between anonymous and pseudonymous?

Anonymous means your posts have no name attached at all. Pseudonymous means you post under a consistent username or handle that isn't your legal name. The key difference is accountability: pseudonymous posts are still tied to one identity you can build a reputation under, while anonymous posts aren't tied to anything.

What is a daily match on a social app?

A daily match is a feature that suggests one new person to you each day instead of an endless feed of profiles. The single-per-day cap is meant to get you to actually message that one person. On Tide, the Daily Tide shows you one interest-matched student from your campus each day.

What does hyperlocal mean for a campus app?

Hyperlocal means content and connections are limited to one specific place — your single campus. A hyperlocal feed shows posts from people at your school only, so events, study requests, and announcements reach the people they're actually meant for instead of a national audience.

What is doxxing and is it allowed on campus apps?

Doxxing is publishing someone's private information — like their full name, dorm, schedule, or phone number — without consent, usually to harass them. It's against the rules on any responsible platform and is a removable, often reportable offense. It's also one of the main reasons fully anonymous campus apps can feel unsafe.

What does karma mean on a social app?

Karma is a score tied to your account that rises when other people upvote or react positively to your posts. Some apps use it to signal a trusted, active member or to unlock features. It can encourage good contributions, but chasing karma can also push people toward whatever gets reactions rather than what's genuinely useful.
