The name
縁文
Enufumi
Remember how good a letter felt?
- 縁 en — Connection — the encounter between people.
- 文 fumi — Writing, a letter, words set down by hand.
Enufumi (縁文) joins two Japanese characters with a special meaning. Together the name stands for connecting people through personal letters.
In an age of fast messages, Enufumi reminds us that genuine words and handwritten thoughts let relationships form and grow.
The app
EnuFumi is a letter-writing app for iPhone, iPad and Android. You write by hand, seal the page, and send it to someone who invited you to correspond. There is an address book, a mailbox, a stamp album, and a drawer for the letters you want to keep.
Slow on purpose
We did not build a faster way to talk — there are enough of those. We built a slower one. A letter costs you a little time and attention, and that is exactly what the person opening it will feel.
Not another message to type. Real handwriting — on digital paper — sealed and sent like mail that still means something.
Nothing here is public
There is no feed, no follower count, no reach to chase. A letter has exactly one reader. Nobody else sees it — not other users, not an algorithm, and not us.
EnuFumi is for people who miss writing — not tapping. Friends, family, penpals: anyone who would smile opening an envelope with their name on it.
Discover
A desk that fits in your pocket
Open EnuFumi and you do not land in a feed. You land at a desk: paper with a texture, a stack of envelopes, a sheet of stamps, and a pen that waits for your hand.
The desk
The whole app is one quiet surface. Warm paper, a little grain, ink that settles as you write. Nothing blinks, nothing counts down, nothing asks you to come back tomorrow. When you close it, it stays closed.
Writing by hand
You write with your finger or with a stylus. Strokes carry speed and pressure, so the line thickens where you press and thins where you lift — it looks like your hand, because it is your hand.
Take your time. Cross a word out and write it again. Draw a small map in the margin. Add another page when one is not enough. There is no character limit and no typing indicator watching you think.
Envelopes and stamps
Before you write, you choose the envelope and place a stamp. It is a small decision, and it changes the letter: you are already thinking about who will open it. Stamps are collected over time, so an envelope can carry a little history of its own.
The mailbox
Letters arrive as post, not as a notification storm. You open the mailbox when you want to, take the envelope out, and unseal it — the paper unfolds in front of you and the handwriting is simply there, the way it was written.
The stamp album
Stamps you collect live in an album you can page through. You place one on an envelope before you write — a small ritual that already belongs to the person who will open it.
The collection
Photos and drawings that arrive with a letter can be kept in a collection of their own. They stay with the correspondence they belong to, not in a camera roll that forgets why they were sent.
The drawer
Letters you want to keep go into a drawer. They stay readable on your device, in order, with the envelope and stamp they arrived in. Re-reading an old letter is half the reason to write one.
The address book
People you write to sit in an address book, not a follower list. Correspondence starts with an invitation or a QR code, can be paused, and can start again when both of you want it to. Nobody writes to you uninvited.
What is deliberately missing
- No feed, no likes, no comments, no reach.
- No read receipts and no typing indicators.
- No advertising, and no data sold to anyone.
- No streaks, no badges, nothing that nags you to return.
How it works
How a letter leaves your hand
A few quiet steps. The interesting part is what happens between sealing and opening.
- Meet Someone invites you, or you share a QR code. Correspondence is never unsolicited.
- Prepare Choose an envelope, pick who it is for, and place a stamp — then the page is yours.
- Write Take your time. Scratch out a line. Add another page. This is writing, not messaging.
- Seal One tap seals it — encrypted on your device — and off it goes with the post.
- Arrive They open an envelope, not a notification storm. And maybe write back.
What stays on the desk
Letters you want to reread go in the drawer. Stamps you collect go in an album you can page through. Pictures that arrived with a letter can be kept in a collection. None of it is a feed.
Sealed means encrypted
When we say seal, we mean it. Your letter is encrypted on your device before it leaves, with a key only your recipient can use. What travels through our servers is a sealed envelope we cannot open.
That also means we cannot recover a letter for you, and we cannot read one on request — not for advertising, not for statistics, not for anyone who asks politely.
Delivery takes a moment
A letter is not an instant message, and it does not pretend to be. It leaves your desk, travels, and arrives in the other mailbox — usually within a moment, and always as a whole letter rather than a stream of fragments.
If you lose your phone
Your keys live on your device, so keep your recovery information somewhere safe. Letters already stored in your drawer belong to that device — treat them like paper, because that is roughly what they are.

- A mailbox of real envelopes, opened when you choose.
- An address book of people you actually write to — invited, never unsolicited.

What it costs
Writing and receiving letters is free. There is no subscription that unlocks your own handwriting, and there is no paywall between you and someone waiting to hear from you.
No ads tucked into your envelope. EnuFumi grows with donations — so letters can stay letters.
Feedback
Letters from the desk
Handwritten notes from people who use EnuFumi. The pen fetches each letter — it does not copy them out.
Donate
Help keep the ink flowing
If EnuFumi makes you want to write again, a donation helps us keep that desk open for everyone — without ads, and without a paywall in front of a letter.
Where it goes
- Servers that carry sealed letters and store nothing they could read.
- Paper, envelopes and stamps — the ones you can see, drawn by hand.
- Development, so the app keeps working on next year's phones.
Quiet letters. No ads. Just room for handwriting. A donation is a one-off thank-you, not a subscription — nothing is unlocked by it, and nothing is taken away without it.
Thank you — genuinely. Every letter that gets written is partly your doing.
Privacy
Sealed is private
Seal means encrypt: your letter is locked on your device before it travels. We never hold a readable copy of your handwriting.
Your letters
Letters are encrypted end to end. They are sealed on your device and opened on your recipient's device. On the way they pass through our servers as ciphertext, and we have no key that would open them.
Your email address
We ask for an email address once, to send you a confirmation code. Once your account is confirmed, that address is deleted from our servers by default — it is not kept, not used for profiles, and not searchable.
If you would like to be told by email that a letter is waiting, you can switch that on yourself during sign-up or later in the app. Only then is an address stored, and you can remove it again at any time.
What we do store
- Your account and its public key, so letters can be addressed to you.
- Sealed letters in transit, until they are delivered.
- The minimum needed to keep the service running and secure.
What we never do
- We do not show advertising and do not sell or share your data.
- We do not build profiles and do not track you across other apps or sites.
- We do not read your letters, because we cannot.
This website
The marketing site itself has no advertising, no analytics trackers, and no third-party widgets. A signed session cookie keeps the page working; we do not use it to profile you.
Age
EnuFumi is for people aged 18 and over.
Your rights
You can ask what is stored about you, correct it, or have your account and its data deleted. Deleting your account removes it from our servers; letters already delivered live on the recipient's device, exactly like paper post.
