Terms of Service

1. About the Service

MOJIKEY is an Android keyboard application that provides Chinese and English input together with user-triggered text AI features, including Reply, Rewrite, Super Talk, Opening, and Translate, as well as AI personas that adapt suggestions to different conversational contexts. The Service includes the mobile app, the on-screen keyboard, account and sign-in infrastructure, and the online services required to operate them. Some features are processed on your device and work without an account; features that transmit text to our online service require a network connection and may require you to be signed in.

2. Eligibility and Accounts

You must be old enough to enter into a binding agreement in your jurisdiction, or have your parent or guardian accept these Terms on your behalf. MOJIKEY does not independently offer accounts or text AI services to children below the applicable age; see the Privacy Policy for details.

When you register or sign in, you agree to provide accurate information, keep your credentials secure, and not share them in a way that lets others access your account. You are responsible for activity that occurs through your account. We may suspend or terminate accounts that are created in violation of these Terms, or that we reasonably believe have been compromised or misused.

3. Free Access and Future Fees

The first public release of MOJIKEY is free — no subscription and no paywall. We may introduce paid features, subscriptions, or usage limits in the future. Any fees will be clearly described before you incur them, and you will not be charged for a paid feature unless you agree to the applicable price and terms. If we discontinue a paid feature, we will provide reasonable notice in accordance with applicable law.

4. Acceptable Use

You agree not to misuse the Service. In particular, you will not:

(a) use the Service to generate, store, or transmit content that is illegal, infringing, defamatory, hateful, sexually explicit, harassing, or that violates the rights of others or our content rules;
(b) attempt to gain unauthorized access to the Service, our servers, or other users' accounts or data, or bypass any security, authentication, or rate-limiting measure;
(c) interfere with the operation of the Service, including by sending automated, excessive, or abusive traffic, or by probing, scanning, or testing the infrastructure without authorization;
(d) reverse engineer, decompile, or extract the source code of the Service except as permitted by applicable law or by the licenses of the open-source components we use;
(e) resell, redistribute, or provide the Service to third parties except as permitted by these Terms;
(f) submit content that you do not have the right to submit, or use the Service to process the personal data of others without a lawful basis;
(g) use the Service in a way that violates applicable law or the terms of any third-party service involved in providing the Service.

We may suspend or terminate access for conduct we reasonably determine violates these Terms, without limiting other remedies available to us.

5. Text AI Features

Text AI features (Reply, Rewrite, Super Talk, Opening, Translate, and similar features) are invoked deliberately by you: text is transmitted to our online AI service only when you choose to use a feature. When you invoke a text AI feature, the text you enter, select, or choose from the clipboard, together with related context such as tone or persona, may be processed by our service and by the third-party AI provider we use for inference, as described in the Privacy Policy.

AI output is generated by machine learning models and may be inaccurate, incomplete, outdated, or otherwise unsuitable. You are responsible for reviewing AI-generated text before sending, publishing, or relying on it, and for deciding what to do with it. Do not submit passwords, verification codes, payment-card details, identity numbers, medical data, trade secrets, or other sensitive information that you do not want a third party to process. If you encounter AI-generated content that you believe is illegal or violates our content rules, you can report it from the More tab of the app as described in the Privacy Policy.

6. Your Content and Intellectual Property

You retain all rights in the text and other content you enter into the Service. To operate the Service, you grant us a non-exclusive, royalty-free, worldwide license to process, transmit, and store that content to the extent reasonably necessary to provide the requested features, operate the Service, and comply with law. We do not sell your personal information.

The Service, including its trademarks, branding, artwork, software, and documentation, is owned by us or our licensors. The keyboard application incorporates open-source components that remain subject to their respective open-source licenses; nothing in these Terms restricts your rights under those licenses.

7. Availability and Changes

We work to keep the Service available, but we do not guarantee uninterrupted or error-free operation. The Service may be temporarily unavailable for maintenance, updates, or reasons beyond our reasonable control. We may change, suspend, or discontinue any feature, including AI features, models, or providers, with reasonable notice where practicable. Features that are not enabled in a particular release are described as such and are not part of the agreed scope of the Service.

8. Privacy

Your use of the Service is subject to the Privacy Policy, which describes what information we collect, how we use it, and the choices available to you. The Privacy Policy is incorporated into these Terms by reference. If there is a conflict between these Terms and the Privacy Policy regarding the handling of personal information, the Privacy Policy controls for that subject matter.

9. Third-Party Services

The Service depends on third-party infrastructure and providers, including Cloudflare for network access, hosting, and security, DeepSeek for language-model inference, and Android, Google, or an app-distribution platform for installation and updates. Your use of those services may also be governed by their own terms and privacy policies. We are not responsible for the acts or omissions of these third parties, except as required by law.

10. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT THE SERVICE WILL MEET YOUR REQUIREMENTS. AI-GENERATED CONTENT IS PROVIDED WITHOUT ANY WARRANTY AS TO ITS ACCURACY, COMPLETENESS, OR SUITABILITY FOR ANY PURPOSE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NEITHER WE NOR OUR OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR LICENSORS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF OR INABILITY TO USE THE SERVICE, INCLUDING DAMAGES RESULTING FROM AI-GENERATED CONTENT, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED US DOLLARS (US$100). NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED UNDER APPLICABLE LAW.

12. Indemnification

To the maximum extent permitted by applicable law, you agree to indemnify and hold harmless us and our officers, directors, employees, agents, and licensors from and against any claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or relating to (a) your use of the Service, (b) content you submit or generate through the Service, (c) your violation of these Terms, or (d) your violation of the rights of any third party. You will cooperate with us in defending any claim to the extent reasonably required.

13. Termination

You may stop using the Service at any time and may delete your account as described in the Account Deletion page. We may suspend or terminate your access to the Service, or delete your account, if you breach these Terms, if we reasonably believe your use poses a security or legal risk, or as required by law. When your account is deleted, your account data is deleted or anonymized as described in the Privacy Policy. Provisions of these Terms that by their nature should survive termination — including sections on acceptable use, intellectual property, disclaimers, limitation of liability, indemnification, and governing law — will survive.

14. Changes to These Terms

We may update these Terms from time to time to reflect changes in the Service, the law, or our business. For changes that materially affect your rights or obligations, we will provide reasonable notice through the app, the website, or another appropriate channel before they take effect. Your continued use of the Service after the updated Terms take effect constitutes acceptance of the updated Terms. If you do not agree to the updated Terms, you should stop using the Service.

15. Governing Law and Disputes

These Terms are governed by the laws of [Governing jurisdiction], without regard to conflict-of-law rules. Any dispute arising out of or relating to these Terms or the Service will be subject to the exclusive jurisdiction of the courts of [Governing jurisdiction], except where applicable law requires otherwise. Nothing in these Terms limits any rights you have under mandatory consumer-protection law in your jurisdiction.

16. General Provisions

If any provision of these Terms is held to be invalid or unenforceable, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect. These Terms, together with the Privacy Policy and the Account Deletion page, constitute the entire agreement between you and us regarding the Service and supersede any prior agreements. Our failure to enforce any provision is not a waiver. You may not assign these Terms without our prior written consent; we may assign these Terms in connection with a merger, acquisition, or reorganization. We may provide notices to you through the app, the website, or the email address associated with your account.
