Take the MBTI once
48 questions, seven-point scale. It's the only questionnaire here — your type and interests become the address on your envelope.
Campus-verified · Students only
Every week,
Every week,
a letter on your wavelength.
Take the MBTI once. Each week you send out one letter — and at Friday's opening time, the post office delivers you one compatible fellow student. No swiping. No feeds. One letter.

Slow down. It's just one letter.
Three steps, once a week. The rest of the time belongs to your life.
✉️
Send this week's letter
Verify your student identity, attach a stamp, and send out the letter that is this week's you. One letter goes out, one comes back.
🕘
Friday, opening time
At the weekly opening time the post office delivers one compatible student from your campus — with why you two were matched.
Built against the swipe.
🎓
Everyone is verified
Campus check-in or school email — every account carries a real student postmark. No bots, no strangers from nowhere.
🧬
Matched, not browsed
MBTI, shared interests, gender preference — the algorithm writes the address. You never scroll through faces.
📮
One a week, on purpose
Scarcity is the feature. One letter deserves a real reply — not an inbox of openers.
🔒
Contact only after a match
Your contact handle is sealed until the letter arrives, and visible only to that one person.
🛡️
Report & block, built in
Block someone and you will never be matched again — enforcement lives inside the matching algorithm itself.
🌏
Three languages
Simplified & Traditional Chinese, and English — including the full 48-question test.
Privacy first
Your letter card is for one reader.
There is no public profile and no public feed. What you write is shown only to your weekly match. Location is used momentarily for campus verification and never shown to anyone. Delete your account any time, in the app.
