DidYet Terms of Service

1. Application

1. These Terms govern all matters relating to the use of the application “DidYet” (the “App”) provided by dekinai (the “Operator”).
2. By downloading, installing, or using the App, you are deemed to have agreed to these Terms. If you do not agree, please do not use the App and uninstall it promptly.
3. Any notices or guidelines the Operator posts from time to time within the App or on this page form part of these Terms.

2. Definitions

1. “Member” means a person or pet you register in the App as the subject of a record.
2. “Item” means a type of activity being recorded, such as medication, meals, bathing, or walks.
3. “Logged Data” means the Members, Items, history entries, and derived totals you create in the App.

3. Description of Service

1. The App is a personal logging tool for recording and checking “when you last did something.” You select Items for each Member and tap to record, then see the last time, elapsed time, and counts for the current day and other periods.
2. The App provides features including listing and deleting records, exporting to CSV, exporting and importing settings and history as JSON backups, switching the display language, and restoring the App to its initial state.
3. Logged Data is stored only in local storage on your device. The Operator does not receive or retain Logged Data.
4. The App requires no account registration and provides no feature for sharing or syncing data between users. To use the same Logged Data on more than one device, use the backup export and import features.
5. The features offered by the App may change as set out in Section 9. Where a feature is marked as “coming soon” or similar within the App, the Operator does not guarantee when, or whether, it will be released.

4. Fees

1. The App is provided free of charge. The Operator does not offer in-app purchases or subscriptions, and does not serve advertising in the App.
2. You are responsible for the device, network connection, and any associated costs required to use the App.
3. If paid features are added in the future, the Operator will revise these Terms in advance and state the details. Features currently provided free of charge will not retroactively be made paid.

5. App Store Terms

The App is distributed through app distribution platforms (each, an “App Store”). In addition to these Terms, you must comply with the terms of the App Store you use. Where these Terms conflict with those of an App Store, the App Store's terms prevail in respect of obtaining and using the App through that App Store.

6. Logged Data and Backups

1. Logged Data belongs to you. The Operator does not view, obtain, or make use of its contents.
2. Because Logged Data is stored only on your device, it may be lost through uninstalling the App, resetting the device, device failure, loss or theft, OS updates, insufficient storage, or your use of the App's “factory reset” or “delete all history” functions.
3. Backing up Logged Data is your own responsibility. The Operator accepts no responsibility for preserving or restoring Logged Data.
4. The App separates history older than a certain period from the main display while continuing to retain it. You can obtain your records for all periods using the export features.
5. History entries store the Member and Item names as they were at the time of recording, so renaming a Member or Item later does not change how past entries appear. This is intentional, so that past records remain readable as they were.

7. Device Permissions

The App may request access to your device's photo library or similar resources to the extent necessary to provide its features, for example when you set an image you have chosen as an Item icon. You may decline these permissions, but some features may then be unavailable.

8. Prohibited Conduct

When using the App, you must not:

1. Violate any applicable law or public order and morals
2. Engage in conduct connected to criminal activity, or infringe the rights or interests of third parties
3. Decompile, disassemble, reverse-engineer, or otherwise analyze the App
4. Copy, modify, adapt, create derivative works from, redistribute, transfer, lend, or sell the App
5. Infringe the copyrights, trademarks, or other intellectual property rights of the Operator or any third party
6. Interfere with the operation of the App or damage its reputation
7. Rely on the App as the sole means of management in medical, nursing, childcare, or other professional settings
8. Engage in any other conduct the Operator reasonably deems inappropriate

9. Changes, Suspension, and Discontinuation

1. The Operator may change, add to, or discontinue all or part of the App without prior notice to you.
2. The Operator may cease providing the App. In that case, the Operator will endeavor to give advance notice where reasonably possible.
3. If the App ceases to be provided, any copy already installed and the Logged Data on your device are not thereby deleted. However, continued operation may no longer be assured, for example after an OS update.
4. The Operator is not liable for any damages arising from changes, suspension, or discontinuation under this Section.

10. Disclaimer

1. The App is not intended to provide medical treatment, medical diagnosis, or medical advice. Records of medication and other activities are supplementary only; actual health management and medical decisions remain your own responsibility and that of a physician or other qualified professional. Do not defer necessary care or medication on the basis of what the App does or does not show.
2. The Operator makes no warranty, express or implied, that the App is fit for any particular purpose, that it has the expected functionality, accuracy, or usefulness, or that it will always be available.
3. The Operator does not warrant the accuracy, completeness, or currency of Logged Data. Entering, deleting, and verifying records is your responsibility.
4. To the extent permitted by law, the Operator is not liable for any damages arising in connection with your use of the App, including defects, incompatibility with your environment, or loss of Logged Data.
5. The preceding paragraph does not apply where the Operator has acted with intent or gross negligence. Where you are a consumer and applicable mandatory law does not permit a full exclusion of liability, the Operator is liable to the extent that law provides.

11. Intellectual Property

1. All intellectual property rights in the App and in the programs, designs, text, images, logos, trademarks, and other information it contains belong to the Operator or their rightful holders.
2. The Operator grants you a non-exclusive, non-transferable right to use the App for personal purposes in accordance with these Terms. These Terms do not transfer any other rights.
3. Rights in the Logged Data you create are reserved to you.

12. Third-Party Services

The App may use analytics services provided by third parties to understand how it is used, and may open external websites from links within the App. The Operator is not responsible for the content of those third-party services and websites. For the scope of information collected and how it is handled, please see the Privacy Policy.

13. Use by Minors

If you are a minor, please use the App with the consent of a parent, guardian, or other legal representative. A minor who uses the App with such consent is deemed to have agreed to these Terms.

14. Changes to These Terms

1. The Operator may change these Terms without prior notice where deemed necessary.
2. Any revised Terms take effect once posted on this page.
3. If you continue to use the App after a revision, you are deemed to have agreed to the revised Terms.

15. Severability

If any provision of these Terms, or part of one, is held invalid or unenforceable under applicable law, the remainder of that provision and all other provisions remain in full force and effect.

16. Governing Law and Jurisdiction

These Terms are governed by the laws of Japan. Any dispute arising in connection with the App or these Terms shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.
