Terms of Use

Last updated: July 2026

By downloading, installing, or using Urilog（うりログ, the "App") on iOS, iPadOS or Android, you agree to all provisions of these Terms of Use. If you do not agree, please stop using the App and remove it from your device.

Plain-language note. Urilog stores everything on your device only. Nobody — including us — holds a copy of your data, so back it up with the App's export feature before switching or wiping devices. Profit and fee figures are calculated from what you enter; they are bookkeeping aids, not tax advice.

1. Acceptance

By downloading or using the App, you are deemed to have agreed to all provisions of these Terms. If you do not agree, please uninstall the App.

2. Grant of License

Subject to your compliance with these Terms, we grant you a non-exclusive, non-transferable, non-sublicensable right to install and use the App on devices you own or control, for your personal bookkeeping purposes.

3. Prohibited Conduct

You shall not:

  • Violate any law, court order, or legally binding administrative measure
  • Act contrary to public order or morals
  • Reverse engineer, decompile, disassemble, or attempt to extract the source code of the App, except to the extent that such activity is expressly permitted by applicable law
  • Copy, modify, adapt, create derivative works of, or translate the App into other languages without our prior written consent
  • Infringe the intellectual property, privacy, publicity, or other rights of any third party
  • Interfere with the operation or security mechanisms of the App

4. User Responsibility and Data

You use the App at your own risk and bear full responsibility for the consequences of your use. All data you enter is stored only on your device; we hold no copy of it. You are responsible for creating backups using the App's export feature — losing or replacing the device, or uninstalling the App, without a backup means the data cannot be recovered by anyone, including us.

5. No Tax, Accounting or Legal Advice

The profit, fee and expense figures the App displays or exports are calculated from the amounts and fee rates you enter. Marketplace fee schedules change over time, and the App's built-in rates may not reflect the rates actually applied to your transactions. The App is a bookkeeping aid: it does not provide tax, accounting or legal advice, and its output does not replace the official statements of the marketplaces you sell on. Verify all figures against official records before using them in a tax return or any other filing.

6. Disclaimer of Data Warranty

We make no warranty of any kind regarding loss, corruption, or alteration of data arising from your use of the App. You are responsible for backing up important data at your own discretion using the App's export and backup features.

7. Intellectual Property

The App, together with all trademarks, copyrights, database rights, and other intellectual property rights related to it, belongs to us. Third-party marketplace names referenced in the App belong to their respective owners; the App is an independent tool and is not affiliated with, endorsed by, or connected to any marketplace operator. The copyrights of open-source software incorporated into the App belong to their respective authors.

8. Changes to the App and these Terms

We may modify or discontinue any feature of the App at any time. We may also amend these Terms. Material changes will be announced via an in-app notice or on this page before they take effect. Continued use of the App after the effective date of revised Terms constitutes your acceptance of the revisions.

9. Termination

If we determine that you have materially violated these Terms, we may suspend or terminate your right to use the App without prior notice. Upon termination, you must uninstall the App; the on-device data remains under your sole control.

10. Disclaimer

The App is provided "as is" and "as available." To the maximum extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, accuracy, and non-infringement of third-party rights.

11. Limitation of Liability

To the maximum extent permitted by law, in no event shall we, our officers, employees, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or data, arising out of or in connection with your use of the App — including any tax assessment, penalty, or loss resulting from reliance on figures produced by the App.

12. Governing Law and Jurisdiction

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