PLEASE READ THESE TERMS CAREFULLY. They include important provisions, such as a binding arbitration agreement (for U.S. users), a class action waiver, disclaimers of warranties, and limitations of liability, that affect your legal rights and obligations.


Quick Summary

This summary is provided for convenience only and does not replace the full Terms below.


1. Acceptance of Terms

By downloading, installing, accessing, or using dekitayo (the "Service"), you agree to be bound by these Terms of Use ("Terms") and our Privacy Policy. If you do not agree, you must not use the Service.

If you are accepting these Terms on behalf of a minor, you represent that you are the parent or legal guardian.


2. Definitions


3. Description of the Service; CDC Attribution

The Service is a mobile application that allows users to record and look back on their child's developmental milestones as a personal "growth album." It is a personal record-keeping and informational reference tool.

The Service includes milestone examples adapted from publicly available materials published by the U.S. Centers for Disease Control and Prevention ("CDC") under its "Learn the Signs. Act Early." program, along with our own additions, translations, illustrations, and arrangements. We may modify, translate, summarize, or reformat such materials, and may incorporate additional content from other publicly available sources, for use in the Service.

The CDC has not reviewed, approved, sponsored, or endorsed the Service, and we are not affiliated with the CDC, the U.S. government, or any health authority. References to the CDC are for source-identification purposes only. We do not use CDC logos, seals, or trademarks except as permitted by applicable law.


4. Eligibility; Parental Supervision; Not Directed to Children

  1. The Service is intended for use by adults (parents, guardians, or caregivers) recording the development of children in their care.
  2. The Service is not directed to children and is not intended for direct use by children under 13. You must not allow children under 13 to use the Service directly.
  3. If you are under the age of majority in your jurisdiction (typically 18), you may use the Service only with the involvement and consent of a parent or legal guardian.
  4. We do not knowingly collect personal information directly from children under 13. If you believe a child under 13 has provided personal information to us, please contact us so we can take appropriate action. See our Privacy Policy for details.

5. License Grant

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the Service on devices you own or control, solely for your personal, non-commercial use.

You may not: - Copy, modify, distribute, sell, lease, sublicense, or create derivative works of the Service; - Reverse engineer, decompile, disassemble, or attempt to derive source code from the Service; - Remove, alter, or obscure any proprietary notices; - Use any automated means to access or interact with the Service.


6. Data Handling; Analytics; Backups

  1. Information you enter in the Service (including your child's name, date of birth, milestone records, photos, and comments) is stored locally within the app on your device and is not transmitted to servers operated by us.
  2. Depending on your device settings, operating system features, and Apple services you use, such information may be included in iCloud backups, device backups, device transfers, or other services provided by Apple or your device platform. We do not control those services.
  3. We and our analytics providers may collect limited usage, performance, and crash information, such as app events, device type, operating system version, approximate region, app version, and pseudonymous app or device identifiers. We do not use this information to identify you or your child, and we do not receive the child profile information, photos, milestone entries, or comments that you store in the app. See our Privacy Policy for details.
  4. You are solely responsible for backing up your data. We bear no responsibility for any loss of data, including but not limited to losses due to device changes, app deletion, device failure, software bugs, or operating system updates.

7. Not an Official Record; No Professional Use

  1. The Service is not intended to be the sole or official record of your child's health or development. You should separately maintain any records that are important to you or that you may need for healthcare, educational, legal, or other purposes.
  2. The Service is intended for personal and family use only. It is not intended for use by healthcare providers, childcare facilities, schools, early intervention programs, researchers, or other professionals as a clinical, educational, regulatory, or official record-keeping system.

8. Prohibited Activities

You agree not to:


9. Intellectual Property

  1. All intellectual property rights in the Service, including but not limited to software, design, illustrations, text, graphics, logos, and trademarks, are owned by us or our licensors. These Terms do not grant you any rights to such intellectual property except for the limited license expressed in Section 5.
  2. The CDC milestone content is based on publicly available U.S. government materials, which are generally not subject to copyright protection. However, our translation, presentation, illustrations, and arrangement of such content are our proprietary work.
  3. You retain all rights to photos, comments, and other content you enter into the Service. Because that content is stored locally and is not transmitted to servers operated by us, we do not claim any ownership of or broad license to that content. You are responsible for ensuring that you have the necessary rights and permissions to store any photos or other content in the Service.

10. DISCLAIMER OF WARRANTIES

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE.

WE EXPRESSLY DISCLAIM ALL WARRANTIES, INCLUDING WITHOUT LIMITATION:

WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT (i) THE SERVICE WILL FUNCTION UNINTERRUPTED, SECURE, OR AVAILABLE AT ANY PARTICULAR TIME OR LOCATION; (ii) ERRORS OR DEFECTS WILL BE CORRECTED; (iii) THE SERVICE IS FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS; OR (iv) THE RESULTS OF USING THE SERVICE WILL MEET YOUR REQUIREMENTS.

Nothing in this Section is intended to limit any non-waivable rights you may have under applicable consumer protection laws. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.


11. MEDICAL DISCLAIMER

THE SERVICE IS NOT A MEDICAL DEVICE AND DOES NOT PROVIDE MEDICAL ADVICE, DIAGNOSIS, OR TREATMENT.

The Service is a personal journaling and informational reference tool only. It is not designed or intended to make individualized medical assessments, screen for or detect developmental delay, autism spectrum disorder, neurological conditions, or other health conditions, or recommend a course of medical care.

The age ranges and progression order shown in the Service are general references derived from public CDC materials and do not reflect what any particular child "should" be doing. Children develop at their own pace, and natural variation is normal.


12. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

(a) IN NO EVENT SHALL THE OPERATOR, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, REVENUE, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO: (i) YOUR ACCESS TO, USE OF, OR INABILITY TO USE THE SERVICE; (ii) ANY CONDUCT OR CONTENT OF ANY THIRD PARTY ON OR THROUGH THE SERVICE; (iii) ANY UNAUTHORIZED ACCESS, USE, OR ALTERATION OF YOUR DATA OR DEVICE; (iv) ANY DEVELOPMENTAL, MEDICAL, OR HEALTH OUTCOME OR DECISION INFORMED BY THE SERVICE; (v) ANY ERRORS, INACCURACIES, OR OMISSIONS IN THE SERVICE'S CONTENT.

(b) IN NO EVENT SHALL THE OPERATOR'S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE EXCEED THE GREATER OF (i) THE TOTAL AMOUNT YOU HAVE PAID TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (ii) ONE HUNDRED U.S. DOLLARS (US$100).

(c) YOU ACKNOWLEDGE THAT THE SERVICE IS PROVIDED FREE OF CHARGE AND THAT THE LIMITATIONS IN THIS SECTION REPRESENT A REASONABLE ALLOCATION OF RISK, AND THAT WE WOULD NOT PROVIDE THE SERVICE WITHOUT THESE LIMITATIONS.

(d) Non-excludable liability. Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable law, including liability for fraud, intentional misconduct, gross negligence, or personal injury where such limitation or exclusion is prohibited by law.

Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages, so some of the above limitations may not apply to you.


13. Indemnification

You agree to defend, indemnify, and hold harmless the Operator, its affiliates, officers, directors, employees, agents, and licensors from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or in connection with:

(a) your misuse of the Service; (b) your violation of these Terms; (c) your violation of any applicable law or regulation; (d) your violation of any third-party right, including any intellectual property or privacy right; (e) any content you submit, post, or transmit through the Service.

This indemnity does not require you to indemnify us for claims caused by our gross negligence, willful misconduct, or violation of applicable law.


14. Apple App Store Additional Terms

If you downloaded the Service from the Apple App Store, the following terms also apply:

  1. These Terms are between you and the Operator only, and not with Apple Inc. ("Apple"). Apple is not responsible for the Service or its content.
  2. The license granted to you is limited to a non-transferable license to use the Service on any Apple-branded products that you own or control and as permitted by the Apple Media Services Terms and Conditions.
  3. Apple has no obligation to provide maintenance or support services for the Service.
  4. To the extent any warranty exists under applicable law that has not been disclaimed, in the event of any failure of the Service to conform to such warranty, you may notify Apple, and Apple may refund the purchase price, if any, for the Service. To the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the Service.
  5. Apple is not responsible for addressing any claims by you or any third party relating to the Service or your use of the Service, including product liability claims, legal or regulatory compliance claims, or claims under consumer protection, privacy, or similar laws.
  6. In the event of any third-party claim that the Service or your possession and use of the Service infringes that third party's intellectual property rights, Apple is not responsible for investigating, defending, settling, or discharging the claim.
  7. You represent and warrant that you are not located in a country subject to a U.S. government embargo or designated by the U.S. government as a "terrorist supporting" country, and that you are not listed on any U.S. government list of prohibited or restricted parties.
  8. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce these Terms against you.

15. Service Modifications and Termination

  1. We may, at our sole discretion and without prior notice, modify, suspend, or discontinue all or any part of the Service, temporarily or permanently.
  2. We may terminate or suspend your access to the Service at any time, without prior notice or liability, for any reason, including if you breach these Terms.
  3. Upon termination, your right to use the Service ceases immediately. Provisions that by their nature should survive termination (including without limitation Sections 6, 7, 9–14, 16–22) shall survive.
  4. We are not liable for any modification, suspension, or termination of the Service.

16. Export Control

You agree to comply with all applicable export and re-export control laws and regulations, including without limitation the U.S. Export Administration Regulations ("EAR") and the sanctions programs administered by the U.S. Office of Foreign Assets Control ("OFAC"). You represent and warrant that: (a) you are not located in, under the control of, or a national or resident of any country embargoed by the U.S. government; (b) you are not on any U.S. government list of restricted or prohibited persons; (c) you will not use the Service in violation of any U.S. or other applicable export laws.


17. Copyright Concerns

If you believe content in the Service infringes your copyright, please contact us using the contact information in Section 22.


18. DISPUTE RESOLUTION; BINDING ARBITRATION; CLASS ACTION WAIVER

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES U.S. USERS TO ARBITRATE DISPUTES AND LIMITS THE MANNER IN WHICH YOU CAN SEEK RELIEF.

(a) Informal Resolution. Before filing any formal claim, you agree to first contact us at the address in Section 22 and attempt to resolve the dispute informally for at least 30 days.

(b) Binding Arbitration (U.S. Users). Except for claims that qualify for small claims court, all disputes, claims, or controversies arising out of or relating to these Terms or the Service ("Disputes") by U.S. users shall be resolved exclusively through final and binding individual arbitration. Arbitration shall be administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules. The arbitration may be conducted by telephone, video conference, written submissions, or, if required by the AAA Consumer Arbitration Rules, in a location reasonably convenient for you. To the extent the AAA Consumer Arbitration Rules require us to pay arbitration filing, administrative, or arbitrator fees beyond the amount you would pay to file a case in court, we will do so, unless the arbitrator determines that your claim is frivolous or brought for an improper purpose.

(c) Non-U.S. Users. For users residing outside the United States, these Terms are governed by the laws of Japan, except to the extent local mandatory consumer protection laws apply. Nothing in these Terms limits your right to bring claims in your local courts where applicable law gives you that right.

(d) Class Action Waiver. YOU AND THE OPERATOR AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, OR REPRESENTATIVE PROCEEDING. Unless we and you both agree otherwise in writing, the arbitrator may not consolidate more than one person's claims and may not preside over any form of representative or class proceeding.

(e) Public Injunctive Relief. Nothing in this Section prevents either party from seeking public injunctive relief in court to the extent such a waiver is prohibited by applicable law (including, without limitation, California's McGill rule).

(f) Severability of Class Waiver. If the class action waiver in subsection (d) is found unenforceable as to a particular claim, then that claim (and only that claim) must proceed in court and not in arbitration.

(g) Equitable Relief Carveout. Either party may seek temporary or preliminary injunctive relief in court to protect intellectual property, confidential information, or security interests, without waiving arbitration for the underlying dispute.

(h) Jury Trial Waiver. TO THE EXTENT PERMITTED BY LAW, YOU AND THE OPERATOR WAIVE ANY CONSTITUTIONAL AND STATUTORY RIGHTS TO A JURY TRIAL.

(i) Opt-Out. You may opt out of this arbitration agreement and class action waiver by sending us a written notice (via the contact channel in Section 22) within 30 days of first accepting these Terms.

(j) Exceptions. Notwithstanding the above, either party may bring an individual action in small claims court for any dispute within that court's jurisdiction.


19. Governing Law and Venue

For users in the United States: These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, USA, without regard to its conflict of laws principles. Subject to Section 18, you submit to the personal jurisdiction of the federal and state courts located in Delaware for any non-arbitrable disputes.

For users outside the United States: These Terms shall be governed by and construed in accordance with the laws of Japan, without regard to its conflict of laws principles. The Tokyo District Court shall have non-exclusive jurisdiction of first instance for any disputes; this does not affect your right to bring claims in your local courts where applicable law gives you that right.

Notwithstanding the above, consumers may have mandatory rights under their local consumer protection laws that cannot be waived by contract, and nothing in these Terms limits such rights.


20. Severability; No Third-Party Beneficiaries; Force Majeure; Entire Agreement

Severability. If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court or arbitrator of competent jurisdiction, the remaining provisions shall continue in full force and effect, and the invalid provision shall be modified to the minimum extent necessary to make it enforceable.

No Third-Party Beneficiaries. Except as expressly provided in Section 14 (Apple App Store Additional Terms), these Terms do not and are not intended to confer any rights or remedies upon any person or entity other than you and us.

Force Majeure. We shall not be liable for any failure or delay in performance caused by circumstances beyond our reasonable control, including without limitation acts of God, war, terrorism, riots, embargoes, acts of civil or military authorities, fires, floods, earthquakes, pandemics, accidents, network outages, or denial-of-service attacks.

Entire Agreement. These Terms, together with our Privacy Policy and any in-app notices, constitute the entire agreement between you and us regarding the Service and supersede all prior or contemporaneous agreements, representations, or understandings.


21. Changes to These Terms

We may modify these Terms at our discretion. Material changes will be communicated through in-app notice or by posting an updated version on this page. Your continued use of the Service after such changes constitutes your acceptance of the revised Terms. If you do not agree to the revised Terms, you must stop using the Service.

Material changes to Section 18 (Arbitration) will not apply to any dispute of which either party had actual notice before the effective date of the change, unless both parties agree.

Revision History


DISCLAIMER: These Terms have been prepared based on legal best practices and reviewed via AI legal counsel (GPT-5.5). They are not a substitute for review by a qualified attorney licensed in each relevant jurisdiction. The Operator should obtain independent legal review before final adoption, particularly for FDA software-as-a-medical-device positioning, COPPA compliance, and enforceability of arbitration clauses in target jurisdictions.
