Who runs GradeLens

GradeLens is run by Ayussh Dussani, a student at Mahindra International School, as a personal project. It is not an official service of the school or of the International Baccalaureate. Questions about your data: [email protected].

What we collect

• Account details: your name and e-mail address. If you sign in with Google, we also receive your Google account id and profile name; we never see your Google password.
• Work you ask us to grade: drafts, task sheets, rubrics and any files you upload, plus the teacher you choose and the prediction we produce.
• Marked work you contribute: the piece of work, the mark, the criterion scores and the teacher's written feedback, if you choose to add them.
• Technical data: standard server logs (IP address, browser type, time of request) kept briefly for security and debugging, and a login cookie so you stay signed in.

We do not collect payment details, location, contacts, or anything from your device beyond what the browser sends with every web request.

What we use it for

• To produce a predicted level and written feedback for the work you submit.
• To show, on a teacher's page, aggregate patterns about what scores well with that teacher. A pattern is only shown once at least six pieces of marked work from three different students support it, and it describes the work, never the teacher or any student. Raw teacher comments and individual submissions are never displayed.
• To show a teacher's GradeLens track record on that teacher's public page and on the grade and result pages: of the newest 10 real marks students added for that teacher, how many times the level GradeLens had shown was at or below the real mark and how many times it was above it (pieces where GradeLens showed no number are left out; where GradeLens showed a level for each criterion and the teacher marked only some of them, the piece is compared on the criteria the teacher marked; where it showed only an overall range and the teacher marked only some criteria, the piece is left out). It is counted strictly: a range whose top is above the real mark counts as above, even when the real mark was inside the range. Only predictions GradeLens made from 15 October 2026 on are counted, and only work from accounts with the “improve GradeLens” box ticked. Nothing is shown until there are at least 5 real marks from at least 3 different students. Once shown, the record changes only when real marks from at least 3 more students have arrived, so one student's new mark never changes it on its own; it still shows how the newest predictions went together, so when they all went the same way, that is true of each of them. If a student whose mark was counted unticks the box, the record is hidden until real marks from 3 more students have arrived. It shows counts only, never a student's name, a piece of work or a mark.
• To improve GradeLens, unless you opt out. On the review step of a submission the box “allow my anonymised work to improve GradeLens” is ticked by default; untick it and nothing from that account is used. While it is ticked, a copy of that submission (your work, the task sheet, the rubric, the predicted level and, later, the real mark) is first stripped of names, e-mail addresses, phone numbers, identifiers and school or class names, both by rules and by a screening model, and given a short summary; anything the screening model is unsure about is held back. That anonymised copy is stored separately, with no link to your account in it, and is what we use to train the grading model; the reading model that picks out themes for the teacher patterns above also reads only that copy. The link that lets us delete it again is kept in our database only. While the box is ticked, your marked work and its real mark also count toward the teacher patterns and the track record above: which work counts, and the counts themselves, are worked out from the submissions in the accounts of students who left the box ticked (simple checks of the submission stand in for the reading model where it has not read the copy yet). Both are only ever shown as aggregates, and stop using your work as soon as you untick the box.
• To keep the service secure and working.

We do not sell your data, show advertising, or share your work with other students, parents or teachers.

Who can see your work

Only you can open your submissions, uploaded files and predictions. Teachers are not rated, ranked or notified. If you are a teacher and want anything about you removed, e-mail us.

Where it is kept and who helps us process it

• Neon hosts our database in Singapore and handles sign-in (including the e-mail code and Google sign-in).
• Amazon Web Services (AWS) runs the website and grading-worker infrastructure, and stores encrypted uploaded files in S3 in Mumbai. AWS Key Management Service manages the encryption keys.
• RunPod runs the grading model on GPU servers in the United States. The text of the work you submit, and any images in it, are sent there to be graded and are not kept there afterwards.
• Cloudflare carries traffic to the site and may collect anonymous, cookie-free performance statistics.
• Google, only if you choose “Sign in with Google”.

All connections use HTTPS, and stored data is encrypted by these providers. Access to the database is limited to the person running GradeLens.

How long we keep it

Your account, submissions and files are kept while your account exists so you can reopen your results. Server logs are kept for a short period only. When you ask us to delete your account, everything linked to it (account details, submissions, predictions, uploaded files and contributed marked work) is deleted within 30 days, except where we must keep a record by law.

Your choices and rights

• You can ask to see, correct or delete the data we hold about you at any time by e-mailing [email protected] from the address on your account.
• You can untick “allow my anonymised work to improve GradeLens” at any time on the review step (it is on by default); every anonymised copy made from your submissions is deleted when you do, and your work stops counting toward teacher patterns and track records.
• You can withdraw consent entirely by deleting your account; the site keeps working for the data already deleted only in anonymous, aggregate form.
• You can sign out on any page; this ends the session on our servers, not just in your browser.

Students under 18

GradeLens is made for MYP students, most of whom are under 18. If you are under 18, use GradeLens only with the agreement of a parent or guardian. Parents and guardians can ask for a child's account and data to be deleted at any time by e-mailing us. We do not track children across other websites, and we do not use their data for advertising or profiling.

Changes

If this policy changes in a way that matters, the date at the top will change and signed-in users will see a notice. Continued use after that means you accept the new version. The Terms of Use say how the service may be used.
