Terms of Use

Effective: 2026-10-09
Updated: 2026-10-09

1. Scope and operator
もじあつめ (Moji Atsume, the App) is a Japanese-letter learning aid for people of all ages, provided by Nexus Inc. (we/us). These Terms set out the conditions for using the App. The terms of your app store and operating system also apply to those services.

2. Use by minors
When a minor uses the App, a parent or guardian should review these Terms and the Privacy Policy and manage the device and use according to the minor's needs. A parent or guardian should handle purchases for minors and support inquiries about a minor. The simple arithmetic parental gate is not identity or age verification and does not replace legally required consent.

3. Current features and requirements
The App offers letter examples, handwriting practice on supported iOS and Android devices, local photo capture and storage, a dated gallery, Sticky Art and home-screen widgets. Using Apple Pencil on iOS requires a compatible iPad or other supported device and Pencil. Consult the store listing and in-app information for supported systems and features. Learning progress and results vary from person to person.

4. Prices, purchases and optional support
Downloading the App and some practice content and designs are free. Additional practice content and designs are available as one-time purchases. Each purchase screen shows the included content and price. Purchased content and designs remain available without a time limit. Ads are limited to optional videos explicitly started from the Hiragana purchase screen. Completing an optional rewarded video unlocks the remaining Hiragana for 72 hours from completion. If Hiragana has not been purchased, the video remains available even when other packs have been purchased. The video reward provides 72 hours of access to the remaining Hiragana. Ads and videos may be unavailable depending on ad availability or connectivity.
“Support this app” is an optional purchase to support the App’s development and operation. The displayed amount is charged each time you choose to purchase. It is separate from purchases of practice content and designs, and past support purchases cannot be restored.
The purchase screen and the store's final confirmation show the price, currency and applicable taxes. You pay any device or network costs. Apple App Store or Google Play handles payment; we do not receive payment-card details. Payment methods and billing timing follow your terms with the store. Purchased features become available after confirmation, which may be delayed by connectivity or pending store transactions.
Restore one-time packs using the same store and account used to buy them. Purchased packs are available through the store and account used to buy them. Request refunds from the store where you purchased; approval follows store policies and applicable law. A confirmed refund or revoked transaction may change access to the affected pack. Statutory cancellation and refund rights remain unaffected.
A parent or guardian must make purchases for a minor. Using free content or opening the App does not incur purchase charges.

5. Drawings and storage
Handwriting and letter-image tiles are handled as follows. Tapping “Done!” makes an image of your ink, without the guide, and places it in the collection grid. “Clear all” clears only the current drawing. Placed tiles are saved on this device as your collection, remain after you leave the screen or close the app, and let you continue next time. Writing a letter again replaces its tile. You can share a collection as an image once it contains at least one collected character, even before it is complete. Sharing happens only when you tap “Share”, through your device's operating-system sharing feature, and what happens after sharing is governed by the destination you choose. We do not receive or store your collection. You can delete a saved collection with “Start over” after completing it, by clearing the App's data, or by deleting the App. Completed letters and practice counts are saved separately on your device for progress display on subsequent use. See the Privacy Policy for language settings, progress and diagnostic information.
The App processes a captured or selected photo locally and adds it to the dated photo gallery only when you choose to save. You can save selected letter images from practice sheets to your Sticky Art hand and letter gallery. We do not alter or receive the original photo. Sticky Art drafts and completed artwork are also stored locally. Widget images are handled on your device. Saving to Photos occurs only when you choose it, and those copies are managed by the photo library. Device failure, data clearing or App deletion may remove your artwork; share or save images you need beforehand.

6. Intellectual property and prohibited conduct
The software, design and materials we provide belong to us or their lawful rights holders. Rights in your drawings remain with you.
Do not use the App unlawfully, infringe others' rights, deliberately disrupt its operation or security, or obtain purchases or entitlements fraudulently. Activities protected by applicable law are not prohibited.

7. Changes, interruption and discontinuation
We may change or temporarily interrupt features for maintenance, bug fixes or security. Except in emergencies, we will endeavor to give advance notice of significant changes or discontinuation in the App or on its public pages. The sales terms and applicable law govern modification or discontinuation of paid features.

8. Responsibility
The App is a learning aid and is not promised to work without errors in every environment. Our responsibility for loss attributable to us is governed by applicable law, including Japan's Civil Code and Consumer Contract Act. This clause does not broadly exclude our liability or limit rights where the law does not permit it.

9. Changes to these Terms
We will explain changes, their reasons and their effective date in the App or on its public pages. Changes will comply with applicable legal requirements; we will seek separate consent where required. Unfavorable terms do not automatically apply retroactively to past use.

10. Governing law and disputes
Japanese law governs these Terms without overriding mandatory protections available to you. Please contact us first to seek a resolution. If a dispute remains unresolved, jurisdiction is determined by applicable law.
