Acceptable Use Policy

This policy applies to all users of lesso.app. It supplements our Terms of Service and Community Guidelines. Violations may result in account suspension or termination.

• Unauthorised access — attempting to access accounts, systems, or data that you are not authorised to access.
• Circumventing paywalls — attempting to access course content without a valid subscription, including through sharing credentials or technical exploits.
• Scraping and automated access — using bots, scrapers, crawlers, or automated tools to access or extract content from the platform without our written permission.
• Reverse engineering — attempting to decompile, disassemble, or derive source code from any part of the platform.
• Malicious code — uploading, distributing, or attempting to execute malware, viruses, or any code designed to harm systems or users.
• Impersonation — impersonating other users, creators, or Lesso staff.
• Interference — attempting to disrupt the platform's availability, security, or performance through DDoS attacks, flooding, or similar means.
• Illegal activity — using the platform for money laundering, fraud, or any other illegal purpose.
• Data harvesting — collecting personal data about other users without their consent.

We reserve the right to implement rate limiting on API access and content requests to ensure fair platform performance for all users. Abnormally high usage volumes may be investigated and, if necessary, restricted.

If you discover a security vulnerability, please report it responsibly to security@lesso.app before disclosing it publicly. We will acknowledge your report within 48 hours and work to resolve verified issues promptly. We do not operate a formal bug bounty programme at this time but may offer recognition for significant responsible disclosures.

Violations of this policy may result in immediate account suspension, permanent banning, and, where appropriate, referral to law enforcement authorities. For access-related violations, we reserve the right to pursue civil remedies under the Computer Misuse Act 1990.
