Terms of Service

1. Acceptance of Terms

By downloading, installing, or using the Ledger mobile application (the "App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the App.

We may update these Terms from time to time. Continued use of the App after changes are posted constitutes your acceptance of the revised Terms. We encourage you to review these Terms periodically.

2. Description of Service

Ledger is a community-powered AI video detection tool. Users can submit video URLs from supported platforms (TikTok, Instagram, Facebook, and X) to check whether content has been flagged as AI-generated. The App provides two primary modes:

• Check Mode allows you to paste a video URL and view the community's verdict on whether the content is AI-generated.
• Swipe Mode allows you to review videos in a queue, cast votes (AI, Not AI, or Skip), and select evidence tags to support your assessment.
• Upload-to-Earn allows you to submit videos you believe should be reviewed by the community.

Ledger does not host, download, or store the video content itself. The App only processes URLs, metadata, and community votes.

3. Eligibility

You must be at least 13 years old to use the App. By using Ledger, you represent that you meet this age requirement. If you are under 18, you should review these Terms with a parent or guardian before using the App.

4. Account Registration

Certain features of the App (such as voting, reporting, and participation tracking) require you to create an account using email/password, Apple Sign In, or Google Sign In.

You are responsible for:

• Maintaining the confidentiality of your account credentials.
• All activity that occurs under your account.
• Notifying us promptly if you suspect unauthorized access to your account.

We reserve the right to suspend or terminate accounts that violate these Terms.

5. Acceptable Use

You agree to use the App only for its intended purposes. You may not:

• Submit false, misleading, or spam reports or votes with the intent to manipulate detection results or community consensus.
• Use automated tools, bots, scripts, or other means to interact with the App in ways not intended by Ledger.
• Attempt to circumvent rate limits, trust scoring, participation gates, or other abuse-prevention measures.
• Use the App to harass, defame, or target any individual or entity.
• Reverse-engineer, decompile, or attempt to extract the source code of the App or its backend services.
• Interfere with or disrupt the App's infrastructure, servers, or networks.
• Use the App for any purpose that violates applicable law or regulation.

6. Trust Score and Participation

Ledger uses a trust-based scoring system. Your votes carry weight based on your accuracy and consistency. Key aspects of this system include:

• Your trust score is calculated based on your voting history and accuracy relative to community consensus and known ground truth.
• Certain features (such as "Report Account") are gated behind minimum participation thresholds (e.g., a minimum number of rated videos).
• Daily usage limits and rate limits apply to prevent abuse and ensure data quality.
• We reserve the right to adjust trust scores, recalibrate scoring models, or reset participation metrics as needed to maintain the integrity of the platform.

7. Content and Verdicts

Ledger's detection results and community verdicts are informational only. They represent the collective assessment of the Ledger community and should not be treated as definitive proof that any video is or is not AI-generated.

You acknowledge that:

• Verdicts may be inaccurate, incomplete, or subject to change as more votes are collected.
• Ledger does not guarantee the accuracy of any AI detection result.
• You should not rely solely on Ledger verdicts for decisions with legal, financial, or other significant consequences.

8. Intellectual Property

All content, design, code, graphics, logos, and trademarks associated with the App are the property of Ledger or its licensors and are protected by applicable intellectual property laws.

You may not reproduce, distribute, modify, or create derivative works from any part of the App without our prior written consent.

By submitting votes, reports, evidence tags, and other contributions through the App, you grant Ledger a non-exclusive, worldwide, royalty-free, perpetual license to use, aggregate, and analyze that data to operate and improve the service and for research purposes.

9. Third-Party Platforms and Content

Ledger allows you to submit URLs from third-party platforms (TikTok, Instagram, Facebook, X). Your use of those platforms is governed by their respective terms of service. Ledger is not affiliated with, endorsed by, or responsible for the content, policies, or practices of any third-party platform.

You are responsible for ensuring that your use of Ledger in connection with third-party content complies with applicable laws and the terms of those platforms.

10. Disclaimer of Warranties

The App is provided on an "as is" and "as available" basis without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

We do not warrant that:

• The App will be available at all times or free from errors or interruptions.
• Detection results or community verdicts will be accurate or reliable.
• The App will meet your specific requirements.

11. Limitation of Liability

To the fullest extent permitted by applicable law, Ledger and its operators, developers, and affiliates shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the App, including but not limited to:

• Reliance on detection results or community verdicts.
• Loss of data, revenue, or reputation.
• Unauthorized access to your account.
• Any interruption or cessation of the service.

In no event shall our total liability exceed the amount you have paid us in the twelve (12) months preceding the claim, or $50 USD, whichever is greater.

12. Indemnification

You agree to indemnify and hold harmless Ledger, its operators, and affiliates from any claims, damages, losses, or expenses (including reasonable legal fees) arising from your use of the App, your violation of these Terms, or your violation of any rights of a third party.

13. Termination

We may suspend or terminate your access to the App at any time, with or without cause, and with or without notice. Reasons for termination may include, but are not limited to:

• Violation of these Terms or the Acceptable Use policy.
• Patterns of abusive, manipulative, or fraudulent activity.
• Extended periods of inactivity (where applicable).

You may stop using the App at any time. Upon termination, your right to use the App ceases immediately, though provisions that by their nature should survive (such as limitations of liability, indemnification, and intellectual property) will remain in effect.

14. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles. Any disputes arising from these Terms or the App shall be resolved in the courts of competent jurisdiction.

15. Severability

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions will continue in full force and effect. The invalid provision will be modified to the minimum extent necessary to make it valid and enforceable.
