Your privacy

Privacy Policy

This is a translation of the Japanese original. If there is any difference between the two, the Japanese version takes precedence.

1. Introduction

This policy explains how information is handled in the iOS / iPadOS app “Sealcho” (the “App”) and on this website (the “Site”). Because the App is intended to be used by teenagers as well, we've tried to keep this policy as easy to understand as possible.

2. The App does not collect personal data

The operator ({{OPERATOR_NAME}}) does not collect any personal data from users through the App.

• There is no server run by the operator.
• There are no accounts and no sign-in.
• The App uses no analytics, advertising, tracking, or third-party SDKs.

This corresponds to “Data Not Collected” in the App Store privacy details.

3. Information stored only on your device

The App stores the following information only on your device. None of it is sent to the operator.

• Sticker images (PNG)
• Sticker layout (page, position, angle, size, and stacking order)
• The date and time each sticker was created or received
• For stickers you received, the name of the person who gave it and a random ID for each transfer (used to avoid adding the same sticker twice)
• The name you registered
• A random per-device ID (used only to keep you out of your own list of people nearby)
• Whether usage tips have been shown

The App does not sync with iCloud or any other service. If you delete the App, this information is removed from your device.

4. How photos are handled

• Cutting out the subject of a photo happens entirely on your device, using Apple's Vision framework. Photos are never sent anywhere.
• The App does not use metadata such as the location where a photo was taken.
• When you choose from your photo library, the App uses the system photo picker and receives only the one photo you select. The App does not ask for permission to read your photo library.

5. What the other person receives when you give a sticker

When you give a sticker to someone nearby, only the sticker image and the name you registered are sent. No date, location, or other information is included. A random ID created for each transfer is also sent so the same sticker isn't added twice; it doesn't identify you.

• If you give away a sticker you received, the name of the person who originally gave it to you is not passed on. The other person receives the name of whoever is giving it now (you).
• Stickers travel directly from device to device (Bonjour over the same peer-to-peer Wi‑Fi that AirDrop uses). They do not go through the internet or any server run by the operator.
• The connection is encrypted with TLS using a pre-shared key.

6. Who can see your name

While the App is open on screen, the name you registered appears in the list of people nearby for anyone close by who has Sealcho's giving screen open. A random per-device ID, used to keep you out of your own list, is also announced to nearby devices at the same time.

• When the App moves to the background, you no longer appear in that list.
• You can change your name at any time in the App's settings.

7. Permissions the App uses and doesn't use

The App does not use location, contacts, or photo library read access.

8. Sharing as an image

Images exported with “画像として共有” (Share as Image) are passed to whatever destination you choose in the share sheet (Photos, Messages, third-party services, and so on). How they are handled there is governed by that service's terms and privacy policy.

9. Children's privacy

The App is intended to be used by teenagers as well. The App does not collect personal data from anyone, regardless of age. Because your registered name is shown to people nearby and sent to people you give stickers to, we recommend using a nickname rather than your real name.

10. This Site and the contact form

This section is about the Site, not the App.

• The Site does not use cookies, analytics, tracking, or web fonts from external services.
• The contact form on the Support page collects your name (optional), email address, device and iOS version (optional), and message.
• Submissions are stored using the forms feature of Netlify, the Site's hosting provider.
• We use what you send only to respond to your inquiry, and for no other purpose.
• If you'd like your submission deleted, please contact us.
• The hosting provider may record access logs (such as IP addresses) to operate its service.

11. Changes to this policy

We may update this policy when needed. If we do, we'll announce it on this page and update the “Last updated” date.

12. Contact
