Tabs That Appear Conditionally

  • The Inventory tab appears when you own at least one item.
  • The Stamps tab appears when you have personal stamps made with Make a Stamp.
  • Explore, Messages, and Shop are always visible.

Start Screen

When you open the app, it starts on Inventory if you own items, or on Explore if you don’t.

💡 On desktop, you can switch tabs quickly with the Ctrl key plus a number key.

📦 Paper

Paper is a currency used when you copy (scrap) a base item to make it your own.

How to Get Paper

Method Amount Note
Link a Google · Apple account 10 sheets Once per linked account
Shop purchase 10 sheets In-app purchase
Recycling reward 1 sheet Delete 10 unused sheets of paper to get 1 new sheet

Using Paper

  • 1 sheet is consumed when you copy a base item.
  • If you run out of paper, you can buy more in the Shop or link an account to receive some.
  • Paper not yet used for copying can also be transferred to other users.

🔖 Stamps

A stamp is an item that lets you create your own info page and transfer it to other users.

Make a Stamp

  1. In your inventory, select a blank stamp that has not been made into a stamp yet.
  2. Select “Make a Stamp” and enter a name for the stamp. (Up to 32 characters)
  3. Once you confirm the name, the stamp is finalized, and afterwards the name can no longer be changed.
  4. In the editor that opens next, arrange images, text, and elements to build the info page, then save.

⚠️ The moment you confirm the name, making the stamp is complete. In the editor you can only change the page layout and images — the name is fixed.

Managing in the Stamps Tab

Personal stamps you have finished making are gathered in the Stamps tab. Tap the ≡ button on the right of each stamp to open its menu.

Menu Description
Edit Edit the info page and images (only for originals you created)
Ownership Check Check whether a specific user owns an item made from this stamp
Transfer Transfer an item to another user
  • Swipe an entry sideways in the list to confirm (mark as read) or abandon management.

Copying (Scrap)

When you find a base item you like in Explore, use the Scrap button on its detail screen to bring it into your inventory.

  • Copying consumes 1 sheet of paper.
  • Each base item can be copied only once.
  • A copy preserves the information exactly as it was at the moment of copying — it does not change automatically even if the original is edited later.

Get Latest Info

When the original is updated, a “Get Latest Info” button appears on your copy. Tap it to update to the latest content, and you can also keep auto-update turned on.

Transferring

Items made from your stamps can be transferred to other users. Specify the recipient by entering their email or domain name, or by scanning their QR code.

When you send a transfer, the recipient gets a toast notification, and when they tap Receive, the transferred copy enters their inventory.

Abandoning Management

For stamps you no longer want to manage, swipe them in the list to abandon management.

  • The pages and conversations of users who have already copied it remain intact.
  • It disappears from your list and cannot be undone.
  • When 10 stamp fragments from abandoned or deleted stamps are collected, you get 1 new stamp back.

🔍 Explore

Discover public base items in the Explore tab.

Browsing

  • Topic categories such as Games · Tech · Movies · Food are shown at the top.
  • Check the Trending Now · New Arrivals rows for popular and fresh content.
  1. Enter a keyword in the search bar at the top.
  2. Suggested keywords and results appear in real time as you type.
  3. Tap a result card to open its detail screen, where you can scrap it.

💬 Direct Messages

You can have direct 1:1 conversations with other users.

Starting a Conversation

There are three ways to start a conversation.

  1. Tap the author of a comment on Explore content and choose Start Message in the profile popup
  2. Enter the other person’s email or domain name in the Messages tab search bar
  3. Find them with a QR scan (scanning fills the search bar automatically)
  • When you reach out, the conversation starts once the other person accepts. If you have both sent requests, or have talked before, it continues right away without acceptance.
  • If the email belongs to someone not yet using the app, you can send an invitation email containing an app install link and QR code.

Messages Tab

  • Your conversations are shown as a list, and unread messages are indicated by a count badge.
  • Swipe an entry sideways to mark it as read or delete the conversation. (It is deleted only on your side — the other person’s history is kept.)

Report · Block

You can report or block someone from their profile popup. Unblocking is done in the blocked list in Settings.

🖼️ Chat Photos & Videos

You can attach photos and videos to messages and community chats.

Sending

  1. In the Media tab of the input bar, tap the Photo or Video button.
  2. Selecting multiple files places them on the stage, where you can drag to reorder or delete them individually.
  3. Tap send to start the upload — the message appears in the conversation immediately, without waiting.

💡 On desktop, only photo attachments are supported.

  • You can bundle up to 16 into a collage in one message.
  • Tap a cell to open the viewer for a larger view, and you can also save them all.

Video Editing

  • Videos can be sent up to 25MB · 60 seconds.
  • If a video exceeds the limit, use video editing to trim the section you want. A size gauge shows the estimated file size.

Links placed in chat are shown as preview cards with a title and image. For video links, tap the card to play right there on the spot.

😊 Emoticons

Add emoticons to conversations to express your feelings.

  1. Open the Emoticon tab in the input bar.
  2. Pick the emoticon you want from a category. (Recently used emoticons are also gathered for you.)
  3. Send it together with text, or send the emoticon on its own.

💡 An emoticon sent on its own is displayed large without a speech bubble, so it stands out more.

🔒 Privacy Protection

Your email address is protected from being exposed as-is.

  • Users wearing a badge are displayed by their domain name instead of their email, and their QR code is also generated from the domain.
  • The email of a user without a badge is represented as a color QR, recognizable only to someone who scans it directly.
  • In community chats seen by many people, the latter part of the email (after the @) is hidden for users without a domain badge.

Name display is reflected in real time — equipping or removing a badge is applied automatically across conversation lists, profiles, and elsewhere.

🏷️ Badges

Engrave a domain name on a badge, and you will be displayed by that name in the app instead of your email.

Engraving

  1. Purchase a badge in the Shop, then select a badge that has not been engraved yet.
  2. Enter the domain name you want. (Up to 32 characters, letters and numbers only, no special characters or emoji)
  3. Use duplicate check to confirm it is available.
  4. Optionally attach a 128×128 image and engrave.

⚠️ Caution: An engraved domain name is permanent and cannot be changed. If you engrave with an image, you can edit the image and keywords afterwards; if you engrave without an image, it cannot be edited later.

Equip / Remove / Edit

  • Equip it to be displayed by your domain name in your in-app activity. Only one can be equipped at a time.
  • Remove it to be displayed by your default email again.
  • Edit lets you change the image and keywords.

📂 Folders

When your items pile up, you can organize them into folders.

  • Drag an item onto the “Create New Folder” area at the bottom to create a folder.
  • Rename a folder by long-pressing its header. (Up to 16 characters)
  • Use the arrow on the folder header to collapse or expand it, and tap the header to select all items in the folder at once.

💡 Folders are stored only on the device you are using. The items themselves are visible on all devices, but folder organization may differ per device.

🛒 Shop

You can purchase the items you need in the Shop.
