## What is postin?

A little love, in a postcard.

“Thank you for today.”
“I can’t wait to see you again.”

With postin, turn your favorite photos and a few heartfelt words into a digital postcard for the person you love.

Share it through LINE. Your partner can open it in their browser—no app download or account needed.

After a date. On a day you wish you could be together. For a birthday or anniversary.
Give them a little something to open, smile at, and cherish.

■ Make it yours
Add a photo, write a message, and decorate your postcard with handwriting, drawings, and stickers.
A stamp is already in place, so you can start creating right away. You can swap it for another one, too.

■ Share through LINE
Create a link to your postcard and send it through LINE.
Your partner simply opens the link to view the card in their browser—even if they don’t use postin.

■ Open now, or save the surprise
Let your partner open the card right away, or choose the date and time it becomes available.
Make it a surprise for midnight on their birthday or the morning of your anniversary.

Note: Scheduling sets when the postcard can be opened. It does not automatically send a LINE message. Please share the link with your partner in advance.

■ Try your first postcard
Create and send a postcard in the tutorial without using a stamp.
Start with a photo you love and something you’ve been meaning to say.

■ Stamps and subscriptions
Regular postcard sending and share-link creation use stamps.
Additional stamps are available through in-app purchases.
An optional subscription includes unlimited sending, subscriber-exclusive stationery, and desk backgrounds.
Receiving and viewing postcards is free.

Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours before the current period ends.
You can manage or cancel your subscription in your App Store account settings.
See the in-app purchase screen for pricing and subscription periods.
