Privacy Policy

This policy describes how Mark That Paper collects, uses and protects personal information. It applies to teachers who hold an account and to the student work they upload, and to students who hold their own account for feedback on their own drafts.

What we collect

Account data: your email, name and billing status. Content data: the rubrics, student labels, uploaded PDFs and extracted text, and the marks and comments you create.

How we use it

To provide the marking service: storing your classes and assessments, extracting text from PDFs, producing AI first-pass suggestions, and generating reports. We do not sell personal information, and we do not use student work to train AI models.

AI processing

De-identified submission text is sent to Anthropic's Commercial API with Zero-Data-Retention solely to generate marking suggestions. See How we handle student data.

Storage, retention and your rights

Data is stored with Supabase under row-level security. You can access, correct, export or delete your data from within the app, and deletion cascades to related records. Contact us to exercise any privacy right.

Sub-processors

Anthropic, Supabase, Vercel and Stripe. See the trust page for details.

Children's data

Student work may relate to minors. For teacher accounts we act as the school's processor, minimise data, de-identify before AI processing, and support deletion.

For student accounts, we deal with the student (and their parent or guardian) directly. Under-18s need a parent or guardian's permission to sign up. The same protections apply: drafts are de-identified before AI processing, are never used to train AI models, and can be deleted at any time. A parent or guardian can contact us to access or delete their child's data.
