Privacy Policy

CoMarker is an Australian AI-assisted essay marking tool designed for teachers and students in K–12 education. For privacy enquiries, contact us at hello@comarker.com.au.

Account information. When you register, we collect your name, email address, and authentication credentials. If you sign in with Google, we receive your name and email from Google.

Student work and rubrics. Teachers upload student essays, task sheets, and rubrics to receive AI-generated feedback. This content is processed solely to provide the grading service.

Grading history. Completed grading results (marks, feedback, teacher notes) are stored in your account so you can review and export them.

Usage data. We collect standard server logs including IP addresses, browser type, pages visited, and timestamps for security and performance monitoring.

Payment information. Subscription payments are handled by our payment processor. We do not store full card numbers.

We use the information we collect to:

• Provide, operate, and improve the CoMarker grading service
• Process student submissions through our AI grading pipeline
• Store and display your grading history within your account
• Send transactional emails (account verification, billing receipts)
• Respond to support requests
• Monitor for abuse, security threats, and service reliability

We do not use student work to train AI models, sell data to third parties, or send marketing without your consent.

CoMarker uses the following third-party services to operate:

• Anthropic (Claude API) — student submissions and rubrics are sent to Anthropic's API to generate grading feedback. Anthropic's API data is subject to their usage policies; Anthropic does not use API inputs to train their models.
• Supabase — stores user accounts and grading history in encrypted databases hosted in cloud infrastructure.
• Vercel — hosts the CoMarker web application.

These processors only receive data necessary to perform their specific function and are bound by appropriate data processing agreements.

CoMarker is used by teachers to mark student work. Teachers are responsible for ensuring they have appropriate permission to submit student work to third-party services, in accordance with their school's policies.

We treat student work as sensitive data. It is not shared with other users, not used for advertising, and not retained beyond what is needed to provide the service. Teachers can delete individual grading entries or request full account deletion at any time.

We retain your account data and grading history for as long as your account is active. If you delete your account, your data is permanently removed within 30 days. Individual grading records can be deleted at any time from within the app.

All data is encrypted in transit (TLS) and at rest. Access to production systems is restricted to authorised personnel. We follow industry-standard security practices and conduct periodic reviews of our data handling procedures.

Under the Australian Privacy Act 1988, you have the right to:

• Access the personal information we hold about you
• Request correction of inaccurate information
• Request deletion of your account and associated data
• Complain to the Office of the Australian Information Commissioner (OAIC) if you believe we have breached the Privacy Act

To exercise any of these rights, email hello@comarker.com.au. We will respond within 30 days.

CoMarker uses session cookies necessary for authentication. We do not use advertising cookies or third-party tracking cookies. You can disable cookies in your browser but this will prevent you from signing in.

We may update this policy from time to time. We will notify registered users of material changes by email. Continued use of CoMarker after changes take effect constitutes acceptance of the updated policy.
