Privacy policy

1. Who this notice covers

H1Soft provides the Nonogram Trip website and is preparing the Android and iOS app for release. This notice describes the website as currently published and the app’s current local-data design. Store availability will be shown separately when verified.

The website and the installed app handle information differently. You do not need to create a Nonogram Trip account to browse the site or play in the app.

2. The website

The website introduces the app, its city routes and collections. It does not collect app progress or provide an account-based journey service.

This version of the Nonogram Trip website does not install analytics scripts or set cookies. When you choose a language or dismiss the language suggestion, the site saves only that preference in this browser’s localStorage. Your browser may also cache ordinary page files as part of loading the site.

The site may read your browser’s language setting to offer a Korean page. It does not automatically redirect you. To remove the saved language and suggestion preferences, clear this website’s site data in your browser.

3. Data inside the app

The app keeps puzzle progress, completed-flight records, collections, play time and preferences in its private storage on your device. It does not send these records to an H1Soft server. Puzzle play does not require an account or an internet connection.

Reminders are optional and use your operating system’s local notification service. Sharing a postcard or exporting a backup happens only when you choose that action and a destination in the system interface.

4. Backups, sharing and deletion

An exported backup contains your journey and preferences. Keep it somewhere you trust. If you save it in a cloud drive or send it to another person, that destination handles the copy under its own rules. A shared postcard similarly goes to the destination you select.

Your device’s normal operating-system backup may include app data, depending on your settings. H1Soft does not operate an account-based sync service or keep a separate recovery copy of your journey.

Resetting records in the app removes its journey records while retaining preferences. Uninstalling the app normally removes its local app data; it does not delete backup files you exported, postcards you shared or copies held by an operating-system backup. Manage those copies through their respective apps or device settings.

5. Website hosting

GitHub Pages hosts this website. Delivering a page involves a request to GitHub, which may process technical information such as your IP address, browser information and request time for its service and security purposes. GitHub’s General Privacy Statement describes its processing.

The website does not access your local app progress. When you follow an external link, the destination’s own privacy practices apply.

6. When you email us

If you choose to email h1.soft.x001@gmail.com, H1Soft receives your email address and whatever message or attachments you send. We use this information to answer your request, investigate a reported problem or respond to a collaboration enquiry. The email providers involved also process the message to deliver and store it.

Please include only what is needed for your question. Do not send passwords, identity documents or unrelated personal information. A screenshot may reveal information outside the game; crop or hide it before sending. We keep correspondence as needed to handle the request and any necessary follow-up. You can contact us to ask about correction or deletion of your correspondence.

7. Your choices and requests

You control the app’s local records, exported files, sharing destinations and notification permission. H1Soft cannot view or change a local journey remotely.

For questions about information you have sent to H1Soft, or a request to access, correct or delete it, email h1.soft.x001@gmail.com. Tell us which correspondence you mean without including unnecessary personal details. Requests about GitHub’s own hosting records should be directed to GitHub.

8. Children’s information

Playing does not require a name, age, profile or account. We do not ask children to submit personal information to play. A parent or guardian can contact us if a child has included personal information in a support message and they would like help removing it.

9. Updates to this notice

If the website or app introduces a different way of handling information, this notice will be updated to explain it. Any relevant store privacy disclosures will also need to reflect the released app. The date above identifies the current notice.

• September 20, 2026 — Updated the website’s scope and support information.
• September 19, 2026 — Initial notice for the pre-release website, user-chosen language preferences, local app records, user-chosen backups and support email.
