These Terms of Use (the "Terms") set out the conditions for using the app "Battery Memo" (the "App"). By downloading or using the App, you are deemed to have agreed to these Terms.
The license to use the App is governed by the Licensed Application End User License Agreement of Apple Inc. ("Apple") that applies through the App Store (the "Apple Standard EULA"). These Terms supplement the Apple Standard EULA. In the event of any conflict between these Terms and the Apple Standard EULA, the Apple Standard EULA prevails.
The App is a memo app for recording, by yourself, the battery types used by your household devices, your battery stock, and where you keep your batteries.
The App is intended to assist your own record keeping, and the accuracy of the records depends on what you enter. You are responsible for managing the information you register.
The App has no account registration, no advertising, no data sharing with other users, and no automatic cloud synchronization.
The App is for iPhone only and requires iOS 17.0 or later.
The App is free to download, and its core features are free to use. Free use includes up to 5 device entries; there is no limit on the number of battery stock entries.
Only if you wish to register a 6th device or more, the feature that removes the limit is offered as a one-time (non-consumable) in-app purchase through the App Store.
The App has no monthly or annual subscription and no automatic renewal of any kind. Once you have paid, no further payment is required for that same feature.
The price is shown on the App Store screen before you buy. Prices may differ by country and over time, and may be changed by Apple.
Purchase, payment, refunds, and all other transaction terms are governed by the conditions set by Apple. The developer does not process payments and cannot process refunds. Refund requests must be made to Apple.
Once purchased, the feature is available via "Restore Purchase" in the App on a new or reinstalled device, as long as you are signed in with the same Apple ID.
Users who are minors should purchase only with the consent of a parent or guardian. If "Ask to Buy" is in use, the purchase is not completed until the organizer approves it.
Users who obtained the App during the period when it was offered as a paid app may use the above feature without any additional payment. This is determined using the "app version in which you originally obtained the App" information provided by Apple.
What you register in the App is stored only on your device. It is not stored on any server operated by the developer, and the App has no automatic cloud synchronization.
As a result, your entries may be lost if your device is lost, breaks, or is reset, if you delete the App, or when you switch to a new device.
If you use iOS backup features such as iCloud Backup, the App's data may be included in your device backup, but whether it can be restored depends on Apple's features and your own settings. The developer cannot guarantee that data can be restored.
For information you cannot afford to lose, we recommend keeping a separate copy rather than relying on the App alone.
In addition, when purchasing or replacing batteries, always check the labels on the actual device and battery as well. Treat the App's records as a guide.
All rights in the photos, device names, memos, and other content you register in the App belong to you or to the third parties holding legitimate rights. The developer acquires no rights whatsoever in them.
Because this content is stored only on your device, the developer cannot obtain, view, or use it.
If you register content that involves the rights of others — for example a photo in which another person appears — you are responsible for handling it appropriately.
All copyrights, trademarks, and other intellectual property rights in the App itself, its program, design, logo, icon, and on-screen text belong to the developer or to third parties holding legitimate rights.
You may not copy, modify, distribute, reverse engineer, or otherwise analyze the App beyond the scope of the license granted by the Apple Standard EULA.
When using the App, you must not:
The App is provided "as is."
The developer makes no warranty that the App is free of bugs, errors, or other defects, that its operation will be uninterrupted, or that it will fit any particular purpose.
To the extent permitted by law, the developer assumes no liability for the following damages incurred in connection with using, or being unable to use, the App:
This does not apply where the damage is caused by the developer's intentional misconduct or gross negligence.
Furthermore, where the Consumer Contract Act of Japan or any other mandatory law does not permit a complete exclusion of liability, this Article does not apply to that extent.
The developer may change the App's contents, add or remove features, or discontinue the App. Where a change is significant, the developer will give advance notice within the App as far as reasonably possible.
The developer may amend these Terms when deemed necessary. Amended Terms take effect when displayed within the App, and material amendments will be announced within the App. If you continue to use the App after an amendment, you are deemed to have accepted the amended Terms.
These Terms are an agreement between you and the developer. Apple is not a party to these Terms.
The developer, not Apple, is responsible for the App and its content.
Inquiries, support, and defect handling relating to the App are provided by the developer. Apple has no obligation whatsoever to furnish any support for the App.
Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms they have the right to enforce these Terms against you.
Your use of the App is also subject to the App Store and Apple Media Services Terms and Conditions.
These Terms are interpreted and applied in accordance with the laws of Japan.
However, if the laws of the country or region where you reside as a consumer contain provisions that apply mandatorily for your protection, these Terms do not prevent those provisions from applying.
For questions about these Terms, please use the contact address below. The App is developed by an independent developer, so replies may take some time.
