Terms of Use

1. Service and acceptance

Hopena Speak provides speaking, listening, vocabulary, Reels, exercises and AI feedback. By using the service after these Terms are made available, you agree to follow them to the extent permitted by law. If you disagree, you may stop using it and request account deletion.

The Privacy Policy explains data processing. Accepting these Terms is not unlimited consent to every processing activity; activities requiring separate consent remain subject to that requirement.

2. Eligibility and accounts

You must be authorised to use your sign-in method and have capacity to accept these Terms under applicable law. A legal representative must be involved where required. Gemini API features are restricted to people aged 18 or older under the provider's terms, even with parental permission.

Protect your account, device and information. Do not impersonate others, share access to bypass limits or use another person's account without permission. Report suspected unauthorised access.

3. Permitted and prohibited use

You may use available features and content for lawful learning purposes. This does not transfer ownership of software, branding or third-party assets.

Do not harass, defraud, infringe privacy or intellectual-property rights, submit unlawful content or malware, access data without permission, bypass authentication, limits or safety measures, or automate requests to overload systems. Security testing requires appropriate authorisation beforehand.

4. Your content

You retain legally recognised rights in your content and are responsible for the right to submit it. You permit us to process, transmit to necessary providers and store content as needed for the features you use, operation and support under the Privacy Policy. These Terms do not transfer ownership of your voice or identity to us.

Words, meanings and pronunciations extracted from practice may enter the shared library as described in the Privacy Policy; dictionary import does not add personal folders or conversation-example sentences to shared records. You may report an entry or content needing removal to support.

Do not provide secrets or unnecessary personal information about yourself or others; submit only material you are authorised to provide.

5. AI limitations

AI information, translations, pronunciation feedback and grammar assessments can be incorrect, incomplete or inappropriate. Output may resemble output provided to others; it is not guaranteed exclusive or free of intellectual-property disputes.

Verify important information and treat feedback as a learning aid. Hopena Speak does not promise examination scores, qualifications, a specific level or time to reach goals. In-app results do not replace official assessment; the service does not provide professional medical, legal or financial advice.

Report errors or inappropriate content to [email protected] with enough information to identify the lesson or incident, without passwords or tokens.

6. Plans and payments

Benefits, limits and prices are those shown when you choose a feature or confirm a purchase. A plan preview, test screen or button without a completed transaction is not proof of payment or paid entitlement.

If subscriptions are sold through App Store or Google Play, the store transaction screen determines price, billing period and renewal terms. Manage subscriptions, cancel renewal, restore purchases and request refunds under store procedures and applicable law. Deleting an app or account does not automatically cancel a store subscription.

Applicable store terms govern transactions and app licensing. These Terms do not remove mandatory refund, warranty or consumer rights.

7. Availability, changes and suspension

The service depends on devices, connections, maintenance, technical limits and third parties; continuous or error-free operation is not guaranteed. Features, AI models and content may change for improvements, system protection or applicable requirements.

Access may be restricted or suspended on grounds of abuse, security risks, a Terms violation or legal requirements. Where appropriate and safe, we will provide notice and an opportunity to contact support. Discontinuation does not extinguish data rights or rights in existing transactions under law.

8. Account deletion and stopping use

You may stop using the service at any time and use Profile → Delete account or email [email protected]. Data is handled under the Privacy Policy and Account deletion page; some shared content and legitimate logs may remain as explained there.

Provisions about content, ownership, legitimately retained data and disputes continue to apply as necessary after use ends.

9. Responsibility and resolving concerns

To the extent permitted by law, the service is provided as available, without a guarantee of fitness for a particular goal or absolute AI accuracy. Use judgment before relying on AI for important decisions.

These limits do not exclude liability that cannot legally be excluded, liability for intentional misconduct or mandatory consumer and data-subject rights. Contact support to investigate and address concerns; you retain the right to complain or seek action from a competent authority under applicable law and are not required to waive those rights.

10. Updates and operator details

The version and update date appear on the document. Material changes affecting rights or obligations receive notice or renewed acceptance where required by law and platform rules. If a provision cannot apply, the others apply to the extent lawful.
