Terms of Service

1. Information Collection

When you log in through Google or GitHub, we collect the following information: username, email address, user ID, and profile picture. This information is used solely for authentication purposes and sending product-related communications.

We also store the sentences you upload and record your actions within the application. These are fundamental components of our service functionality and are used solely to provide the service.

All information we collect is used only to provide the service and is not shared with third parties or used for model training purposes.

For more details about how we handle your information, please refer to our Privacy Policy.

You can request termination of your account by contacting our customer support team. After terminating your user account, we will immediately and permanently delete all personally identifiable information you provided to us (including your account information), though we may retain non-personally identifiable demographic information, data we collected during your use of the service, and your user content for as long as we deem appropriate.

2. Service Usage License

Unless otherwise stated, we or our licensors own the intellectual property rights in the service and service content. You may only use the service and service content for personal language learning, subject to the restrictions set out in these terms and other limitations.

You may not copy, redistribute, sell, rent, sublicense, publicly display, publicly perform, provide, modify, transmit, or otherwise exploit the service content outside of the service, whether for commercial purposes or not. If we specifically allow use of service content outside the service, such use requires adherence to additional licensing.

You must not use the service in any way that causes, or may cause, damage to our website or impairment of the availability or accessibility of the service; or in any way which is unlawful, fraudulent or harmful, or in connection with any unlawful, fraudulent or harmful purpose or activity.

You must not use the service to copy, store, host, transmit, send, use, publish or distribute any material which consists of (or is linked to) any spyware, computer virus, Trojan horse, worm, keystroke logger, rootkit or other malicious computer software.

You must not conduct any systematic or automated data collection activities on or in relation to the service without our express written consent.

You must not use the service to transmit or send unsolicited commercial communications. "Bunn" and all other trademarks, service marks, graphics and logos used in connection with the service (collectively, "Marks") are trademarks or service marks of Bunn or their respective owners, some of which may be registered. Nothing in these terms grants you any right to copy or otherwise use these Marks.

3. User Generated Content

In these terms, "your user content" means material (including without limitation text, images, audio material, video material, and audio-visual material) that you submit to the service, for whatever purpose.

User Content
All content you upload or provide to this service (including but not limited to text, images, audio, etc.) remains your property. This service will not use your content for commercial purposes or make it available to other users.

License Grant
You grant us a non-exclusive, worldwide, royalty-free license solely for storing, processing, and providing the service. This license terminates when you delete your content or account.

Content Deletion
You can delete your content at any time, or delete all data through account management. We will delete the relevant data within a reasonable timeframe, though there may be brief storage delays due to technical reasons such as backups.

Your user content must not be illegal or unlawful, must not infringe any third party's legal rights, and must not be capable of giving rise to legal action against you, us, or a third party (in each case under any applicable law).

You must not submit any user content that is or has been the subject of any threatened or actual legal proceedings or other similar complaint.

4. Payment and Refunds

You can cancel your subscription at any time. After cancellation, you can continue using the service until the end of the current month, but refunds are not allowed.

All paid plans require a valid credit card. Free accounts do not require a credit card number.

Upgrading from the free plan to any paid plan will result in immediate billing.

Service fees are charged monthly or annually in advance. We do not provide refunds or credits for partial months of service, upgrades/downgrades, or unused months.

All fees are exclusive of all taxes, levies, or duties imposed by taxing authorities, and you shall be responsible for payment of all such taxes, levies, or duties, excluding only United States (federal or state) taxes.

Downgrading your service may cause the loss of features or capacity of your account. Bunn does not accept any liability for such loss.

5. Changes to Terms

We may modify these terms from time to time. Modified terms will apply to your use of the service from the date the modified terms are posted on our website, or from such later date as may be specified in the modified terms.

If we modify these terms, we will notify you (for example by email or when you next use the service). If you do not agree to the modified terms, you may request termination of your user account.

6. Entire Agreement

These terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding your use of the service and supersede all prior agreements regarding your use of the service.

7. Exclusion of Third Party Rights

These terms are for the benefit of you and us and are not intended to benefit any third party or be enforceable by any third party. The exercise of our and your rights in relation to these terms is not subject to the consent of any third party.
