Terms of Service

Last revised: September 27, 2026 (effective October 11, 2026)

These Terms set out the conditions for using the iPhone app “Time with My Parents,” including buying Premium, where data is stored, and how to contact us.

These Terms of Service (the “Terms”) set out the conditions for using the iPhone app “Time with My Parents” (the “App”; shown as “Time with Parents” on iPhones set to a language other than Japanese) provided by the Time with My Parents Secretariat (the “Secretariat”). These Terms also set out the rights and obligations between the Secretariat and people who use the App (“Users”). Users must agree to these Terms on the App’s consent screen before using the App.

This English version is a translation. The Japanese version is the original, and if the two differ, the Japanese version prevails.

Article 1. Application

  1. These Terms apply to all relationships between the Secretariat and Users regarding the use of the App.
  2. If anything shown in the App or any description of the App on the Secretariat’s website differs from these Terms, these Terms prevail.

Article 2. Definitions

In these Terms, the words below have the following meanings.

  1. “Agreement” means the agreement for the use of the App that is formed between the Secretariat and a User on the terms of these Terms when the User agrees to these Terms on the App’s consent screen.
  2. “Premium” means the paid features purchased within the App.
  3. “Secretariat’s website” means the website operated by the Secretariat (https://oyatonojikan.com).

If the App’s name or content changes, “App” includes the App after the change.

Article 3. Features of the App

  1. The main features of the App are:
    • registering profiles of the User, the User’s family members, and others, showing a list of their ages (the Age Chart), and saving or sharing the Age Chart as an image;
    • registering events, showing them in the App’s calendar, and receiving event notifications;
    • browsing example events in Suggestions and adding them to the User’s own events;
    • estimating how many more times things can be done together (How Many Times Left?);
    • exporting and importing data; and
    • the Premium features set out in Article 4.
  2. The Secretariat may change the names or content of features through updates to the App. However, the Secretariat will remove a feature shown as Premium on the purchase screen, or change it in a way unfavorable to Users, only in a case described in Article 16, paragraph 1. In that case, the Secretariat will set the change and the date it will release the App update containing the change, and will announce both on the Secretariat’s website at least two weeks before that date.
  3. The App can be used on iPhones running a supported iOS version as shown on the App Store. Some features may be temporarily unavailable because of iOS updates or the device model.
  4. Users pay for the devices and data connection needed to use the App.
  5. The App shows ads when Premium is not available. Any transaction on a site or app reached from an ad is between the advertiser and the User.

Article 4. Premium

  1. Users can buy Premium from More > Premium in the App. Premium is unlocked by a one-time purchase, and there are no recurring charges. The price and the features included in Premium are shown on the purchase screen.
  2. Features added to Premium after a User’s purchase are also available to that User at no additional charge.
  3. Payment is charged to the User’s Apple Account through the App Store at confirmation of purchase. Refund requests are handled and decided under Apple’s procedures.
  4. On an iPhone signed in with the same Apple Account used for the purchase, tapping More > Premium > Restore Purchases makes Premium available again.
  5. If a Premium feature does not work as described on the purchase screen, the Secretariat will fix it through an update to the App within a reasonable period.

Article 5. Relationship with App Store terms

  1. The App is provided through Apple’s App Store. In addition to these Terms, the terms set by Apple (the Apple Media Services Terms and Conditions and the license agreement that applies to the App on the App Store) apply to obtaining the App, paying for Premium, refunds, and re-downloading.
  2. The Secretariat, not Apple, handles matters concerning the content of the App and provides support for it.

Article 6. Where data is stored

  1. Data entered in the App is stored on the User’s iPhone and is not kept by the Secretariat. The Secretariat cannot see the data and cannot restore lost data.
  2. As needed, Users should export their data with More > Data Management > Create Export Data and save the exported file themselves.

Article 7. Prohibited conduct

When using the App, Users must not:

  1. violate laws or public order and morals;
  2. use the App to infringe the copyright, portrait rights, privacy, or other rights of others;
  3. modify the App or interfere with its operation; or
  4. place an excessive load on systems the Secretariat operates, such as the contact form.

Article 8. Termination and end of the Agreement

  1. If a User violates these Terms, the Secretariat may terminate the Agreement with that User only if the Secretariat has asked the User to correct the violation within a reasonable period and it has not been corrected within that period, or if the violation is serious and the Agreement cannot continue.
  2. Users may end the Agreement at any time by deleting the App from all of their devices.
  3. Articles 11, 12, 14(2), 18, and 19 remain in effect after the Agreement ends.

Article 9. Ending the service

The Secretariat may stop distributing, updating, or supporting the App. If it does, it will announce this on the Secretariat’s website at least 30 days in advance.

Article 10. Figures shown in the App

The age highlighted in the Age Chart and the counts shown in “How Many Times Left?” are estimates based on statistics and the information the User enters. They do not show how long the User or the User’s family members will live, or how many times they will actually be able to do those things.

Article 11. Liability

  1. If a User suffers damage in connection with the App for reasons attributable to the Secretariat, the Secretariat will compensate for that damage. However, except in cases of willful misconduct or gross negligence by the Secretariat, the amount of compensation is limited to the greater of the amount the User paid for Premium or 1,000 yen.
  2. The limit in the preceding paragraph does not apply to damage to the User’s life or body.
  3. The Secretariat is not liable for damage arising from causes not attributable to it, such as natural disasters, outages of Apple’s services, or failures of communication lines.

Article 12. Rights

  1. Copyright and other rights in the text, images, design, programs, and other content of the App belong to the Secretariat or to third parties who hold the rights.
  2. Except as permitted by law or by the license agreement referred to in Article 5(1), Users must not copy, modify, distribute, or sell the App.
  3. Rights in the text and photos Users enter in the App remain with the User or the third party who holds them.

Article 13. Handling of User information

The Secretariat handles User information in accordance with the App’s Privacy Policy.

Article 14. Feedback and surveys

  1. Users can send feedback through More > Feedback in the App or through surveys conducted by the Secretariat.
  2. Users permit the Secretariat to use the feedback they send, free of charge, to improve the App and the Secretariat’s website.

Article 15. Contact and notices

  1. Inquiries about the App are accepted through the form on the contact page of the Secretariat’s website or by email at oyatonojikan@gmail.com.
  2. The Secretariat gives notices to Users by posting them on the page of these Terms or the App’s introduction pages (https://oyatonojikan.com/app/ in Japanese and https://oyatonojikan.com/en/ in English) on the Secretariat’s website, or by showing them in the App through an update.

Article 16. Changes to these Terms

  1. The Secretariat may change these Terms when:
    • the change is in the general interest of Users; or
    • the change does not go against the purpose of the Agreement and is reasonable in light of the need for the change, the appropriateness of the new content, and other circumstances of the change.
  2. When changing these Terms, the Secretariat will set the date the change takes effect and, before that date, post on the Secretariat’s website that these Terms will change, the new content, and the effective date. Changes unfavorable to Users will be posted at least two weeks before the effective date.
  3. The Secretariat may ask Users to agree to the revised Terms on a screen in the App after an update.

Article 17. Transfer

  1. Users may not transfer their status as a party to the Agreement or their rights and obligations under these Terms to a third party.
  2. If the Secretariat transfers the business related to the App to a third party, it may transfer its status as a party to the Agreement and its rights and obligations under these Terms to that party.

Article 18. Severability

If any provision of these Terms is held invalid under law, the other provisions remain in effect.

Article 19. Governing law, jurisdiction, and language

  1. These Terms and the Agreement are governed by the laws of Japan.
  2. The Tokyo District Court has exclusive jurisdiction as the court of first instance over any dispute between the Secretariat and a User arising out of or in connection with these Terms or the use of the App.
  3. Paragraphs 1 and 2 do not take away any protection that a User who is a consumer living outside Japan has under the mandatory laws of their country of residence, including laws that protect consumers and laws on which courts can hear a dispute.
  4. These Terms are written in Japanese. If this English translation differs from the Japanese Terms, the Japanese Terms prevail.

  1. These revised Terms apply from October 11, 2026.
  2. Until the day before that date, the previous Terms apply (Terms of Service established February 13, 2025, in Japanese).
