Terms of Use

These Terms of Use (the “Terms”) govern the children’s creative app SayDraw (the “Service”) provided by GREATEARTH CO., LTD. (the “Company,” “we,” or “us”).

• Effective date: October 20, 2026
• Version: 2026-10-20

Article 1 (User and Application)

1. The account user and contracting party is the guardian (legal representative), not the child. The guardian reads and accepts these Terms and the Privacy Policy and manages and supervises the child’s use.
2. A child uses the Service only through a profile under the guardian’s account and cannot independently create an account, accept terms, make a purchase, or delete the account.
3. The guardian confirms that they have legal authority to accept these Terms and permit the child to use the Service.
4. Initial availability is limited to the countries and regions enabled by the Company in the app stores. We do not offer the Service as a child-directed service in the United States until separate controls required there, including verifiable parental consent where applicable, are implemented.

Article 2 (Service)

1. The Service converts a child’s spoken creative request to text, screens it for safety and personal information, creates images such as coloring-page line art, and lets the child color, store, and view the work.
2. The voice recording is sent through our server to OpenAI for transcription, and our server does not persist the original audio in a database or artwork store. If identifying information is detected after transcription or safety cannot be determined with confidence, generation stops without further AI processing or storage by us.
3. We send OpenAI the voice recording, recognized text, constrained generation instruction, and generated image for speech transcription, safety screening and child-appropriate interpretation, image generation, and output safety review. A coloring artwork being posted to the artwork board, and feedback-board posts and comments, are sent only to OpenAI Moderations for safety screening. Account and profile identifiers are not included. The Privacy Policy and guardian consent screen explain the items sent, purposes, retention conditions, and third parties.
4. AI output is probabilistic and may differ from the guardian’s expectations or resemble another output. We take reasonable steps not to provide output whose safety cannot be confirmed, but do not guarantee a particular result, accuracy, or completeness.
5. The Service provides an artwork board and a feedback board under Article 8.

Article 3 (Account, Consent, and Guardian Responsibility)

1. The guardian must keep account information accurate and secure the sign-in method and device.
2. The guardian must use only a nickname for the child profile and guide the child not to enter or say a real name, school, address, contact details, or other unnecessary personal information.
3. A child profile, artwork generation, AI transfer, and payment are available only after the guardian actively consents to the current Privacy Policy and these Terms. The server verifies the consented versions and timestamp.
4. We request renewed consent after a material document change and may block related features until renewed consent is given.
5. Payments, data deletion, and account management are available only in the guardian area and behind an adult-verification step.

Article 4 (Privacy and Third-Party Services)

1. The Privacy Policy governs the categories collected, collection methods, purposes, recipients, international processing, retention, deletion, and guardian rights.
2. Before any transfer, the guardian can review and consent to each item sent and each third party, including OpenAI, on the consent screen.
3. We do not use children’s data for advertising, behavioral tracking, or sale, and do not provide a feature that publishes it on the web (such as public links or public profiles). However, under Article 8, coloring artworks the guardian chooses may be shown to other families in the app, without the child’s name, once they pass automated safety screening. In addition, in the guardian area of the app, the guardian may choose an artwork (a coloring page or a colored picture), one at a time, and send it directly through the device’s share feature (such as messaging or social media apps). This feature is not available on the child’s screens, no other information, such as the child’s name, is sent with the picture, and it does not pass through our servers. Any forwarding or posting after sending is the guardian’s own action, and we cannot control or reverse it.
4. The guardian may withdraw consent and request account deletion in the guardian area or by contacting dev@g-e.biz. Future processing stops when the request is made, and final deletion of account and child data follows the 30-day grace procedure in Article 10.

Article 5 (Safety and Prohibited Conduct)

1. We apply server-side safety checks to every generation path. If safety cannot be confirmed or processing fails, no output is delivered and the credit reserved for that generation is not consumed or is returned.
2. A user must not:
   • bypass or disable a safety control, guardian gate, authentication, usage limit, or payment verification;
   • intentionally seek violent, sexual, hateful, self-harm, illegal, or otherwise child-inappropriate content;
   • enter personal information about themselves or another person, including a real name, address, school, contact details, or credentials;
   • infringe another person’s copyright, trademark, publicity, privacy, or other rights;
   • interfere with or exploit the Service through automation, excessive requests, reverse engineering, malware, or fraudulent payment; or
   • violate law or public order.
3. If a violation is reasonably suspected, we may block the request, limit account use to the extent necessary, and cooperate with authorities where required by law.

Article 6 (Credits and Payment)

1. Some generation features use credits. Credit packs are sold through Apple App Store in-app purchase. Price, tax, currency, and billing time are shown in the App Store purchase sheet.
2. Credits are granted to the guardian account after server-side verification of the store transaction or receipt. A child cannot make a purchase.
3. Credits may be used only within the Service and may not be redeemed for cash or transferred to another account or service. Purchased credits have no separate expiration date while the account remains open, but all remaining credits expire, regardless of type, when final account deletion under Article 10 is completed.
4. If a generation is not completed because of a safety block, provider error, or our processing failure, the credit reserved for that generation is returned.
5. Cancellations and refunds follow applicable law and the applicable app store’s policy and procedure. Except where those procedures or applicable law require otherwise, we generally do not provide direct cash refunds. If a service failure is attributable to us, we may grant separate goodwill credits, but goodwill credits do not replace or limit any cancellation, refund, or rescission right under app-store policy or mandatory law. If the store approves a refund, we may reclaim the corresponding credits or adjust the balance, but we do not separately charge a shortfall.
6. If we discontinue the Service, we give reasonable advance notice, stop selling new credits, and take measures required by applicable law for unused purchased credits.

Article 7 (Artwork and Intellectual Property)

1. Rights in the Service software, trademarks, designs, characters, user interface, and Company-provided materials belong to us or the applicable rights holder.
2. Existing rights in content directly entered or drawn by the guardian or child remain with the applicable rights holder. We receive only a non-exclusive right to process it as necessary to provide, store, display (including display to other users on the boards under Article 8), safety-check, support, and delete it at the guardian’s request.
3. Depending on the jurisdiction, creative contribution, and generation process, generative-AI output may not qualify for copyright or exclusive rights. To the extent we acquire rights in an output, we permit the guardian to use those rights for the child as allowed by applicable law.
4. We do not guarantee that an output is unique or non-infringing. If the guardian publishes, sells, or commercially uses an output outside the Service, the guardian is responsible for checking applicable law and third-party rights.

Article 8 (Boards)

1. In the guardian area of the app, the guardian may choose an artwork that was made from app-generated line art, colored in the app, and saved, and post it to the artwork board. A child cannot post, and device photos, screenshots, or pictures from other apps cannot be posted. A post is the picture as it was when posted; later coloring is not reflected.
2. A posted picture is shown to other families in the app as soon as it passes the line-art match and automated safety screening. The artist is shown by an automatically assigned nickname instead of the child’s name, and other families can leave only heart, star, and clap reactions. Our operators may review published pictures and reports and hide or delete them.
3. Only guardians we invite may use the feedback board. Posts and comments are visible to the other guardians taking part in the feedback board and to our operators, and the author is shown by an author number such as “Guardian 12.” Posts and comments go through automated safety screening each time they are written or edited, and must not include information about a child or contact details.
4. The guardian may withdraw an artwork post and delete their own feedback posts and comments at any time. Deleting the original artwork, the child profile, or the account also deletes the related post.
5. A guardian may report a post that is inappropriate or exposes personal information. After a report, the reported guardian’s posts are hidden from the reporting guardian’s screen, and we review the report.
6. We may reject, hide, or delete a post, and add or remove feedback-board participants, where necessary because of a breach of these Terms or for safety or privacy. Posts and comments already written remain after a participant is removed.
7. The Privacy Policy governs the processing and retention of board information.

Article 9 (Changes, Suspension, and Account Restrictions)

1. We may change or suspend a feature for safety, security, legal, provider, or operational reasons. We give reasonable advance notice of a material adverse change. For an urgent safety or security reason, we may act immediately and notify afterward.
2. We may temporarily limit a request or account to the extent necessary if we reasonably suspect a breach of these Terms, fraudulent payment, security risk, or infringement of another person’s rights.
3. A guardian may challenge a restriction by contacting dev@g-e.biz.

Article 10 (Account Deletion and Termination)

1. The guardian may request account deletion and begin termination of the agreement at any time in the guardian area or by contacting dev@g-e.biz.
2. When the guardian finally confirms the deletion request, the account is signed out and suspended immediately. To allow an accidental request to be reversed, we retain the authentication account, child data, artwork, and remaining credits for 30 days from the request. The Service cannot be used with that account during the grace period.
3. If the guardian completes a new sign-in during the grace period and a new authentication session is issued, the deletion request is automatically cancelled and the account restriction is lifted. Retained data and remaining credits become available again. The session that existed when deletion was requested, or a mere token refresh for that session, does not cancel the request.
4. If no new sign-in session is issued within 30 days after the request, the next daily deletion job after the deadline permanently deletes or revokes child profiles, artwork, recognized text, generation instructions, support threads, private-storage objects, and the SayDraw authentication account and active sessions managed by Supabase. At that time, the right to use all remaining purchased, free, and goodwill credits expires; credits cannot be restored or transferred to another or newly created account. It does not delete the guardian’s Apple ID itself. Transaction records required by law are disconnected from account and child content and kept only for the required period. Final deletion and credit expiration do not affect refund rights under applicable law or app-store policy.
5. If part of final deletion fails, the deletion request remains recorded and is retried until completion. Completed final deletion cannot be undone.

Article 11 (Scope of Warranty)

1. The Service is a tool for children’s creative play and does not provide educational, medical, legal, or other professional services.
2. We operate the Service with reasonable care, but to the extent permitted by law do not warrant uninterrupted availability, compatibility with every device, any particular output, permanent data storage, or uninterrupted third-party services.
3. The guardian may save important artwork separately and must provide appropriate supervision of the child’s use.

Article 12 (Limitation of Liability)

1. To the extent permitted by applicable law, we are not responsible for loss caused by communications failure, app-store, AI, or cloud-provider failure, natural disaster, or another event outside our reasonable control.
2. No limitation in these Terms applies to our willful misconduct or gross negligence, death or personal injury, or liability that cannot be limited under the Consumer Contract Act or another mandatory law.
3. Nothing in these Terms excludes rights or remedies that the guardian has under mandatory consumer law in the guardian’s place of residence.

Article 13 (Changes to These Terms)

We may change these Terms to reflect legal, safety, Service, or privacy changes. We announce a material change before its effective date and request the guardian’s consent to the new version. If the guardian does not agree, the guardian may delete the account, and related features remain unavailable until renewed consent is given.

Article 14 (Governing Law and Disputes)

1. These Terms are governed by Japanese law.
2. To the extent permitted by applicable law, courts with jurisdiction in Tokyo have exclusive jurisdiction in the first instance over disputes concerning the Service.
3. Mandatory law in the user’s place of residence concerning consumers, privacy, minors, or jurisdiction prevails where applicable.
