Privacy Policy

CypherCrescent (“we”, “us”) provides Sepal Solver and the associated learning platform, documentation, and support channels. This Policy applies to our websites, web applications, and related online Services.

For privacy requests, contact privacy@cyphercrescent.com.

We may collect:

• Account data : name, email, organization, role, and credentials if you register or redeem access
• Usage data : pages viewed, curriculum progress signals, feature usage, and approximate timestamps
• Runner data : code you submit to the interactive runner, execution metadata, and error diagnostics needed to operate the service
• Device & log data : IP address, browser type, referring URL, and security logs
• Communications : messages you send to support or legal/privacy contacts

We use information to:

• Provide, secure, and improve the Services
• Authenticate users and enforce licenses
• Operate the code runner and prevent abuse
• Respond to support and legal requests
• Analyze aggregate usage to improve curriculum and product quality
• Send service-related notices (and marketing only where you opt in or as otherwise permitted by law)
• Comply with legal obligations

If you are in a jurisdiction that requires a legal basis for processing (for example the EEA/UK), we rely on: performance of a contract; legitimate interests (securing and improving the Services); consent where required; and legal obligations.

We do not sell your personal information. We may share data with:

• Infrastructure and hosting providers that process data on our instructions
• Analytics or error-monitoring tools configured for product reliability
• Professional advisors (legal, accounting) under confidentiality
• Authorities when required by law or to protect rights and safety
• A successor entity in connection with a merger, acquisition, or asset transfer

We use cookies and similar technologies for essential session management, security, and (where enabled) analytics. You can control cookies through your browser settings; disabling essential cookies may break sign-in or runner features.

We retain personal data only as long as needed for the purposes described above, including legal, accounting, and security requirements. Runner submissions may be retained for a limited period for abuse prevention and debugging, then deleted or anonymized.

We implement administrative, technical, and organizational measures designed to protect personal data. No method of transmission or storage is completely secure; please use strong passwords and protect your account.

We may process and store information in countries other than where you live. Where required, we use appropriate safeguards for cross-border transfers.

Depending on your location, you may have rights to access, correct, delete, or export your personal data, object to or restrict certain processing, and withdraw consent. To exercise these rights, email privacy@cyphercrescent.com. We may need to verify your identity before responding.

The Services are directed to professionals and learners and are not intended for children under 16. We do not knowingly collect personal data from children under 16. If you believe we have, contact us and we will take appropriate steps.

We may update this Policy periodically. We will revise the “Updated” date and, for material changes, provide additional notice where appropriate.
