Terms of Service

Last updated: June 2, 2026 Effective date: June 2, 2026

These Terms of Service ("Terms") govern your access to and use of the LexSee mobile application and related services (the "Service") provided by Leo Yang ("we," "us," or "LexSee"), an individual sole proprietor based in Nashville, Tennessee, USA.

By creating an account or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 13 years old to use the Service. If you are between 13 and 17, you represent that your parent or legal guardian has reviewed and agreed to these Terms on your behalf.

You also agree that:

You will not use the Service if doing so is prohibited by the laws of your country.
The information you provide during sign-up is accurate.

2. Your Account

You are responsible for keeping your account credentials confidential. You are responsible for all activity that occurs under your account. If you believe your account has been compromised, contact us immediately.

You may delete your account at any time via Settings → Identity → Delete account. Once you delete your account, your data is removed within 30 days as described in the Privacy Policy.

We may suspend or terminate your account if you violate these Terms, abuse the Service, attempt to harm other users, or for any reason at our reasonable discretion. We will provide notice where reasonable.

3. Subscriptions and Payments

Some features of LexSee may require a paid subscription. Subscription details are presented in-app before purchase.

3.1 Billing

Subscriptions are billed through your Apple App Store or Google Play account. Payment is charged to your store account at the time of purchase and at the start of each renewal period.

3.2 Renewal

Subscriptions auto-renew at the end of each billing period unless you cancel at least 24 hours before the renewal date. The renewal price is the price displayed at the time of subscription, subject to any future price changes communicated at least 30 days in advance.

3.3 Cancellation

You can cancel your subscription at any time via your Apple App Store or Google Play subscription settings. Cancellation takes effect at the end of the current billing period — you retain access until then.

3.4 Refunds

We do not directly issue refunds. Refund requests for in-app purchases are handled by Apple or Google according to their refund policies. To request a refund, follow Apple's process at reportaproblem.apple.com or Google Play's refund flow.

3.5 Free trials

If you start a free trial, we will not charge you until the trial ends. To avoid being charged, cancel before the trial period ends. Trial eligibility may be restricted (one trial per Apple ID or Google Play account, typically).

4. Acceptable Use

You agree NOT to:

Use the Service for any unlawful purpose.
Upload images that infringe third-party copyrights, depict illegal acts, contain nudity or sexually explicit material, harassment, hate speech, or graphic violence.
Attempt to access another user's account or data.
Reverse-engineer, decompile, or disassemble any part of the Service.
Scrape, mirror, or otherwise extract data from the Service in bulk without our written permission.
Interfere with the operation of the Service (denial of service, automated abuse, etc.).
Use the Service to send spam or unsolicited messages.

We reserve the right to remove content and suspend accounts that violate these rules. Repeated or severe violations may result in permanent termination.

5. Your Content

You retain ownership of any content you upload (images, notes, etc.).

By uploading content to the community image gallery, you grant us a worldwide, non-exclusive, royalty-free license to host, display, and distribute that content within the Service, including showing it as a possible image for the relevant word to other users. This license persists for as long as the content remains on the Service.

You represent that:

You own the content you upload, OR you have a valid license to upload it (e.g., the photo is yours, or it is licensed under Creative Commons or public domain with attribution honored), AND
The content does not violate the Acceptable Use rules in Section 4.

You may delete your uploads at any time via the My Uploads tab.

6. Our Content

The Service, including all software, design, text, graphics, and the bundled dictionary, is owned by us or our licensors. Definitions in the bundled dictionary are derived from Wiktionary (Wiktextract project) and are available under the Creative Commons Attribution-ShareAlike 3.0 Unported License (CC BY-SA 3.0). AI-generated content (definitions, translations, audio) is generated by third-party AI providers (OpenAI, DeepSeek) — we make no warranties about its accuracy.

You may use the Service for your personal, non-commercial language learning. You may not reproduce, distribute, or create derivative works of the Service itself without our written permission.

7. AI-Generated Content Disclaimer

LexSee uses AI services (OpenAI, DeepSeek) to generate definitions, translations, and pronunciations for words not covered by the bundled dictionary. AI output may contain errors, inaccuracies, or biases. You should not rely on AI-generated definitions for academic, professional, or critical-decision contexts without independent verification.

If you find an inaccurate AI-generated definition, please report it via the Contact form so we can correct or remove it.

8. Modifications to the Service

We may modify, update, or discontinue any part of the Service at any time. We will give reasonable notice for changes that materially affect your experience or any paid features you depend on.

If we discontinue a paid feature you are actively paying for, we will provide a prorated refund or alternative access at our discretion.

9. Disclaimers and Limitation of Liability

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.

We do not guarantee that:

The Service will be uninterrupted or error-free.
AI-generated definitions or translations will be accurate.
Your data will never be lost (though we maintain backups — see Section 8 of the Privacy Policy).

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM ARISING FROM OR RELATED TO THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU HAVE PAID US IN THE 12 MONTHS PRECEDING THE CLAIM, OR (B) USD $50.

We are not liable for indirect, incidental, special, consequential, or punitive damages, including lost profits, lost data, or business interruption, even if we have been advised of the possibility of such damages.

Some jurisdictions do not allow the exclusion of certain warranties or limitations of liability. To the extent prohibited by applicable law, the above limits do not apply to you.

10. Indemnification

You agree to indemnify and hold us harmless from any claims, liabilities, damages, losses, and expenses (including reasonable attorney's fees) arising out of:

Your use of the Service in violation of these Terms,
Your violation of any rights of another person or entity, or
Content you upload that infringes third-party rights or violates Section 4.

11. Governing Law and Dispute Resolution

These Terms are governed by the laws of the State of Tennessee, USA, without regard to its conflict-of-laws principles.

Any dispute arising out of or related to these Terms or the Service shall be resolved as follows:

Informal resolution first. Contact us at the address below. We will attempt to resolve any dispute in good faith within 60 days.
Binding arbitration. If informal resolution fails, any remaining dispute will be resolved by binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. The arbitration will be held in Davidson County, Tennessee, or remotely if both parties agree.
Class action waiver. You agree to bring any dispute solely in your individual capacity, not as part of a class or representative action.
Exception. Either party may bring a claim in small-claims court if it qualifies, or seek injunctive relief in court to protect intellectual property rights.

This arbitration provision does not preclude you from filing a complaint with a government agency.

12. Apple-Specific Terms (iOS users)

These additional terms apply if you obtained the Service from the Apple App Store:

These Terms are between you and us, not Apple. Apple is not responsible for the Service or its content.
Apple has no obligation to provide maintenance or support for the Service.
If the Service fails to conform to any applicable warranty, you may notify Apple, who will refund the purchase price; otherwise, Apple has no warranty obligation.
Apple is not responsible for product liability claims, third-party intellectual property claims, or claims under consumer protection law arising from the Service.
Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them.

13. Changes to These Terms

We may update these Terms from time to time. When we do, we will post the updated Terms here with a new "Last updated" date. For material changes, we will notify you in-app the next time you open LexSee.

Continued use of the Service after a Terms update constitutes acceptance of the updated Terms. If you do not agree to the updated Terms, you may close your account.

14. Miscellaneous

Entire agreement. These Terms and the Privacy Policy constitute the entire agreement between you and us regarding the Service.
Severability. If any provision of these Terms is held unenforceable, the rest remain in effect.
No waiver. Our failure to enforce a provision does not waive our right to enforce it later.
Assignment. You may not assign your rights under these Terms. We may assign our rights, e.g., in connection with a sale of the business.
