Privacy Policy

Comparison corpus. To detect plagiarism, submitted code may be retained and compared against other users' submissions and publicly available sources.

Product demonstration. We may publicly display brief, de-identified excerpts of submitted code to illustrate how the Service works. We take commercially reasonable steps to remove or blur identifying details — including student and institution names, file paths, comments, string literals, and secrets — and we do not publish information intended to identify the student, the source submission, or the institution. You may contact us at any time to opt out of this use.

Rapid / single-tenant privacy. Code submitted on our isolated, single-tenant (Rapid) plan is kept private to your account: both during and after your subscription, it is never added to the shared comparison corpus, never used to check other customers, and never shown in our public examples. This applies to code submitted while Rapid is active. Code uploaded before Rapid was activated entered the shared corpus at the time of upload and is not withdrawn from it retroactively by activating Rapid.

Deletion of uploaded code requires Rapid. The ability to delete submissions, checks, and courses is a capability of the Rapid add-on. While Rapid is active you can delete this content on demand, including content uploaded before you activated Rapid, and we stop using deleted content for cross-account matching. On every other plan, including free trials, free accounts, and paid base plans that do not include Rapid, uploaded code cannot be deleted by you, by our support staff, or by closing your account, and it remains in the anonymized comparison corpus indefinitely. This is a condition of those plans and is set out in full in Section 5.1.1 of our Terms of Service. For the same reason, self-service account deletion is available only while your account holds no uploaded code, or while Rapid is active: if your account holds uploaded code on another plan, the dashboard will ask you to activate Rapid before the account can be deleted. None of this affects the statutory rights described under Your Rights below, which apply to your personal data and which you can exercise by contacting us at any time.

This includes transactional emails, service updates, newsletters, and promotional communications. You may unsubscribe from marketing emails at any time via the link in any email or your account settings.

Deletion and the comparison corpus. Your right to have personal data erased applies to the personal data we hold about you, such as your account, profile, billing, and contact records. It is not a general right to withdraw uploaded code from the anonymized comparison corpus. Code contributed to that corpus on a non-Rapid plan is retained in de-identified form, is no longer linked to you as an identifiable person, and is therefore outside the scope of an erasure request. Where we can honor an erasure request only in part, we tell you which part and why.

If you need on-demand deletion of your uploaded code, the Rapid add-on provides it, and keeps your submissions out of the shared corpus entirely. See Terms of Service, Section 5.1.1.

Closing your account. Because closing an account deletes the code it holds, self-service account deletion is available only when your account holds no uploaded code, or when Rapid is active. Otherwise, activate Rapid first, or contact us: we will action the personal-data rights above (access, correction, erasure of your account, profile, billing, and contact records) without the de-identified corpus content needing to be deleted.
