How it works
You write a letter. You seal it. You send a link. The other person opens it like an actual envelope — turns it over, breaks the wax, pulls out the pages. No account needed, on either side. The letter lives online for 72 hours, then it's gone.
The four steps
- Write. Pick a paper style — classic, note, telegram, postcard, elegant or vintage — and write as many pages as you want. You can throw in photos, stickers and a song too.
- Seal. Choose colours for the background, the envelope, the lining, the wax. Address it, add a stamp. It ends up looking like something you'd actually want to open.
- Lock it (or don't). By default, the letter will only open on the first device that clicks the link — so if they open it on their phone, that's the only phone that can read it. You can turn this off if you want. You can also set a secret word.
- Send the link. Copy it, or hit the WhatsApp button. The preview in the chat shows a sealed envelope in your colours — never the words or photos inside.
When they open it, they get the full experience: turning the envelope, cracking the seal, pulling out pages. And when they're done, they can write back — a reply letter, with the names already filled in.
Privacy, without the fine print
- We don't know who you are. No sign-up, no email, no phone number. Ever.
- Your draft stays on your phone (or computer) until you decide to create a link. Before that, nothing leaves your device.
- 72 hours, then deleted. The letter is wiped from our server and the link stops working. We don't keep backups of it.
- Secret words are real encryption. If you set one, the letter gets locked on your device before it's uploaded. We only ever see the scrambled version — so even we can't read it.
- The person reading your letter never sees ads. Ads only show up while you're writing. They never touch the letter itself — no tracking, no data, nothing. Details in our privacy policy.
Frequently asked questions
Is it free?
Completely. Writing and sending letters costs nothing. We keep the lights on with ads shown to people while they write — the person receiving the letter never sees any.
Does the other person need an account or an app?
Nope. They just tap the link and it opens in their browser. Works on phones, tablets, computers — anything with a browser.
What does "first device only" actually mean?
Whichever phone or computer opens the link first gets to keep the letter. After that, it only works on that device, in the same browser. This is on by default to make sure only the person you wrote to reads it. One thing: don't open the link yourself to "check" — use the "Test Receiver View" button instead, or you'll lock yourself out of your own letter. You can turn this off before sending if you'd rather not use it.
How does the secret word work?
You pick a word (and optionally a hint). Tell it to the other person separately — not in the same message as the link, obviously. Upper and lower case don't matter. If the word gets lost, the letter is gone too, because we genuinely never have it on our end. Ten wrong guesses in an hour locks the letter for a while to stop brute-force attempts.
Can I keep a letter longer than 72 hours?
The online link always expires at 72 hours — that's the whole point. But before you send, there's a "Download Receiver .HTML" button in the send window. That gives you a file you can keep forever, open offline, even email as an attachment. Same envelope, same seal, no internet needed.
What can I put inside?
Handwritten-style pages (as many as you want), photos, stickers, and one song (MP3, up to 12 MB). The whole letter can be about 20 MB total.
Is it really private?
The link contains a long random code that can't be guessed — only someone with the exact link can open it. Add a secret word and not even we can read it. That said, no online service can stop someone from taking a screenshot, so the same rule as paper applies: write for someone you trust.
My link says the letter expired. Can you get it back?
No, sorry. Once it's gone, it's gone — that's by design. If you still have the draft saved on your device, you can create a fresh link from it.
Can I delete a letter before the 72 hours are up?
Yes. Send us the link using the contact on our privacy page and we'll delete it right away.
