Tickd helps maths teachers mark handwritten exam papers. This page says, in plain words, what we collect, why, who handles it, and when it is deleted.
What we collect
- When you request access: your name, email, school or university, role, what you teach and a rough class size.
- When you have an account: your email and login details, your page limit and how many pages you have used.
- For each exam: the markscheme file, the scanned pages with the name area blacked out, the marks and remarks Tickd suggests, your changes, and a history of those changes.
- To stop abuse: a scrambled (hashed) version of your network address, kept for at most two days.
Student names
You choose the name area on the scans. Your browser blacks it out before anything is uploaded, on every page unless you choose otherwise. Please check the preview: if a student writes their name somewhere else, it is uploaded with the page. Students appear in Tickd as numbers (Student 01, Student 02) in scan order.
Why
Only to mark your papers, show you the results, and run your account. We do not sell data or use it for advertising.
Who handles it
- Supabase stores accounts, exams and files, and runs logins.
- Vercel hosts the website.
- Resend sends our emails (invites, login links, replies to requests).
- Anthropic’s Claude reads the scanned pages and the markscheme through Anthropic’s API. Anthropic says it does not use this data to train its models without permission, and does not keep the pages or its answers after replying, unless its safety systems flag a request or the law requires it. See Anthropic’s data retention page.
Who can see your exams
Only your account. Each teacher’s exams are kept apart by rules in the database. The person who runs Tickd can reach stored data to fix a problem or when the law requires it, and does not look at your exams otherwise.
How long we keep it
- Exams, with their scans, marks and history, are deleted automatically 30 days after upload. You can delete an exam sooner.
- Your account stays while you use Tickd. Ask us and we delete it, with everything in it.
- Access requests are kept while we decide, and with your account if we invite you.
Cookies
Only the cookie that keeps you logged in. No tracking or advertising cookies, and no analytics.
Your rights
You can ask to see, correct or delete your data at any time. Use the contact form and say what you need.
Your school
Before uploading, you confirm that your school allows you to upload this student work. Your school decides what students and parents are told.
