Learning information
Privacy for your study record
What is saved
When enabled, Clerk handles sign-in and account details. The learning database stores your Clerk user identifier, lesson status, notes, revision numbers and save times. Exercise submissions contain your answers, objective check results, ungraded written responses, marking-version identifiers and submission times. It does not need a copy of your name or email address.
Who can access it
The application authorises each request to the signed-in learner. Other learners cannot read or edit your record. The site operator and service providers with authorised technical access may process stored information. Notes are not end-to-end encrypted. Avoid sensitive personal information and information about other people.
History and retention
Current progress is kept until erased. The latest 500 saved note versions are retained; saving more removes the oldest note text. Compact daily status milestones and save counts remain until you erase your learning record, so an older learning trajectory is not silently lost. These daily summaries do not keep historical notes. The service also retains save identifiers, payload hashes and response metadata to recognise a repeated save safely; these contain no note text and are erased with your learning record.
The latest 500 full exercise attempts are retained. Older attempts lose their answer text, while answer-free outcome receipts remain until erasure to recognise retries without counting or scoring them twice. The service limits submissions to 10 per minute and 100 per 24 hours. It retains answer-free submission timestamps for that rolling window; expired timestamps are removed on your next account operation. Cleanup for inactive accounts must be configured before collection opens.
Export and erase
My learning provides a JSON export of retained information and an erase action. Exports include retained exercise attempts and answer-free outcome receipts. Erasing removes progress, notes, recent versions, daily summaries, exercise answers and outcome receipts. Recent answer-free submission timestamps remain for the 24-hour anti-abuse window so erasure cannot bypass checking limits. Signed provider-account deletion removes these timestamps immediately. A minimal identifier and revision marker remain to reject delayed writes from old tabs. Erasing learning data does not delete your Clerk sign-in account.
Once account-deletion delivery is enabled and verified, deleting the sign-in account triggers removal of its learning information. A minimal deleted-account marker, containing the provider user identifier and deletion-receipt time, prevents an already-issued token from recreating the data. It does not retain notes, email, name or webhook payloads. Account-deletion delivery can be delayed; an issued token can otherwise remain valid until its short expiry.
In this browser
This application keeps private notes and exercise answers in page memory rather than local storage. Signing out, changing accounts or leaving the page clears its private state. A downloaded export remains on your device until you remove it. Use sign out when sharing a device.
Before accounts open
Account collection remains disabled until the operator confirms a privacy contact, applicable age and regional requirements, data-retention and backup-erasure policy, the minimal deletion-marker retention period, and the configured service providers. Those launch decisions are still required before a public account service opens.
