Terms of Use

End User License Agreement · Last updated 31 August 2026

This End User License Agreement (the “Agreement”) is a legal agreement between you and GUC Inc. (“we”, “us”) for the copipi application, including the main app, its custom keyboard, and any accompanying components (together, the “App”).

By downloading, installing, or using the App, you agree to this Agreement. If you do not agree, do not use the App.

This Agreement is between you and us only. Apple Inc. and Google LLC are not parties to this Agreement and are not responsible for the App or its content, except as set out in Section 12.

1. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control, for your own personal or internal business use.

• iOS — this licence is limited to Apple-branded devices, and is subject to the Usage Rules in the Apple Media Services Terms and Conditions.
• Android — this licence is subject to the Google Play Terms of Service.

We retain all rights in the App that are not expressly granted to you. The App is licensed, not sold.

2. What you may not do

You may not:

• copy, redistribute, sell, rent, lease, sublicense, or lend the App;
• reverse engineer, decompile, or disassemble the App, except where that restriction is prohibited by applicable law;
• remove or obscure any notice of ownership;
• use the App to store or transmit content that is unlawful, or that you do not have the right to store;
• attempt to bypass the limits of the free tier or the subscription checks.

3. Free tier and copipi Pro

The App is free to use with a limit on the number of saved entries. The current limit is 20 entries. We may change this limit for future releases; a change will not remove entries you have already saved.

copipi Pro removes the limit. It is an auto-renewing subscription offered on a monthly or annual basis.

• Payment is charged at confirmation of purchase — iOS to your App Store account, Android to your Google Play account.
• The subscription renews automatically at the end of each period unless you cancel at least 24 hours before the period ends.
• Your account is charged for renewal within 24 hours before the end of the current period, at the price then in effect.
• You can manage or cancel your subscription in your account settings — iOS App Store, Android Google Play. Deleting the App does not cancel a subscription.
• Prices are shown in the App before purchase and may vary by region.

Refunds are handled by the store you bought from, under Apple’s or Google’s refund policies. We cannot issue refunds directly.

Subscriptions purchased on one platform do not carry over to the other. An iOS subscription does not unlock Pro on Android, and vice versa, because the two stores manage entitlements separately.

4. Your content

The text you save in the App is yours. We do not claim any ownership of it.

Your entries are stored on your device. We do not operate a server for the App and we cannot read, retrieve, or restore your entries.

A copy may leave your device through iCloud (iOS), Android’s backup (Android), or a file you export yourself. Those are operated by Apple and Google under their own terms, and are described in the Privacy Policy.

You are responsible for keeping your own backups. If you delete the App, reset your device, or lose access to your store account, your entries may be lost permanently.

5. The keyboard

The App includes a custom keyboard that inserts text you have saved.

The keyboard does not record, collect, or transmit what you type. What it reads and writes, and why your device shows a warning when you enable it, are set out in the Privacy Policy, which forms part of this Agreement.

6. Privacy

Our handling of data is described in the Privacy Policy, which forms part of this Agreement.

In short: the App does not include analytics, advertising, or third-party tracking, and does not send your entries to us.

7. Updates and changes

We may release updates that change, add, or remove features. Where an update removes a feature you rely on, we will try to say so in the release notes.

We may amend this Agreement. If we make a material change, we will update the date above and, where reasonable, note it in the App or its release notes. Continuing to use the App after a change means you accept the amended Agreement.

8. Term and termination

This Agreement applies for as long as you use the App.

You may end it at any time by deleting the App. We may end it if you materially breach it. On termination, the licence in Section 1 ends and you must stop using the App. Termination does not by itself refund a subscription; see Section 3.

9. No warranty

The App is provided “as is” and “as available”, without warranty of any kind, to the fullest extent permitted by law. We do not warrant that the App will be uninterrupted, error-free, or compatible with every device or every other application.

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this Section may not apply to you. Nothing in this Agreement limits rights you have as a consumer that cannot be limited by law.

10. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages, or for lost data, lost profits, or business interruption, arising out of your use of or inability to use the App.

Our total liability arising out of or relating to the App will not exceed the greater of (a) the amount you paid us for the App in the twelve months before the event giving rise to the claim, or (b) JPY 1,000.

Again, nothing here limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, or for fraud.

11. Support

Support is provided by us, not by Apple or Google. How to reach us is set out on the Support page. We aim to reply, but we do not guarantee a response time or that any particular issue will be resolved.

12. Terms that apply to the App Store version

The following apply where you obtained the App from the Apple App Store. They are required by Apple and take precedence over conflicting terms elsewhere in this Agreement.

1. This Agreement is between you and us only, not with Apple. We, not Apple, are solely responsible for the App and its content.
2. Scope of licence. The licence granted in Section 1 is a non-transferable licence to use the App on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
3. Maintenance and support. We are solely responsible for providing maintenance and support for the App. Apple has no obligation to provide any maintenance or support.
4. Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent they are not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are our sole responsibility.
5. Product claims. We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your use of it, including product liability claims, claims that the App fails to conform to a legal or regulatory requirement, and claims arising under consumer protection or similar legislation.
6. Intellectual property claims. In the event of a third-party claim that the App infringes that party’s intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement, and discharge of that claim.
7. Legal compliance. You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
8. Third-party terms. You must comply with any applicable third-party terms of agreement when using the App.
9. Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of this Agreement, and upon your acceptance, Apple has the right (and is deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary.
10. Contact. Questions, complaints, or claims about the App should be directed to [email protected].

13. Terms that apply to the Google Play version

The following apply where you obtained the App from Google Play.

1. This Agreement is between you and us only, not with Google. Google is not a party to it and is not responsible for the App or its content.
2. Your use of Google Play is also governed by the Google Play Terms of Service and any other terms Google applies.
3. Billing, renewals, and refunds for copipi Pro are handled by Google under Google’s policies.
4. Support is provided by us, not by Google. See Section 11.

14. Governing law

This Agreement is governed by the laws of Japan, without regard to its conflict of law rules. The Tokyo District Court will have exclusive jurisdiction as the court of first instance for disputes arising out of this Agreement.

If you are a consumer resident in a country whose law gives you the protection of mandatory local rules, those rules continue to apply to you.

15. General

If any provision of this Agreement is held unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver of it. This Agreement, together with the Privacy Policy, is the entire agreement between you and us regarding the App.
