Please check the following:

• Ask the other person to open Sealcho too. You can only find each other while the app is open.
• Turn on Wi‑Fi on both devices. You don't need to be connected to the same Wi‑Fi network, because the devices connect to each other directly.
• In the Settings app, go to Privacy & Security → Local Network and make sure Sealcho is turned on.

Make sure the other person is nearby and that you both have the app open, then try again.

Try keeping just one subject in the shot, fitting it inside the guide frame, and keeping it apart from the background. Busy backgrounds or a subject that appears small can make cutouts fail.

In the Settings app, go to Privacy & Security → Camera and allow Sealcho. You can also make a sticker by choosing a photo from your library instead of using the camera.

Tap the gear button at the top right of the sticker book to open Settings, where you can change your name under “あなたの名前” (Your name).

You can delete a sticker in either of these ways. Deleted stickers can't be restored.

• Touch and hold the sticker to enter edit mode, then tap the delete button at its top-left corner.
• Tap the sticker to open its details, then tap “削除する” (Delete).

Not at this time. There is no cloud sync or backup feature, and stickers are stored only on the device.

Use “画像として共有” (Share as Image) in the sticker's details to send it as an image. Because it's only an image, it won't be added to the other person's sticker book.

An Android version is planned. For now, Sealcho is available only for iPhone and iPad (iOS / iPadOS 26.0 or later).
