Effective: August 11, 2026 · Version: 1.4 · Owner: James Kang, Founder (hello@nudgelearn.app)
Published pursuant to the Children's Online Privacy Protection Act (16 CFR Part 312) as amended effective April 22, 2026. This policy is binding on NudgeLearn and is referenced from our public Privacy Policy.
NudgeLearn collects personal information from account holders (teachers and parents) and from the student work they upload, to operate the NudgeLearn Grader: a photo-based grader for worksheets, tests and essays. This policy specifies, for each category of personal information we collect: (a) the purpose of collection, (b) the specific business need that justifies continued retention, and (c) the timeline after which the information is deleted or anonymized.
No personal information is retained indefinitely. No personal information is retained longer than reasonably necessary to fulfill the purpose for which it was collected.
| Category | Purpose | Business need | Timeline |
|---|---|---|---|
| Account holder email, Stripe customer ID, subscription status | Account management and billing | Required to service the account and to meet tax and accounting obligations | Active subscription + 7 years after cancellation |
| Uploaded image of student work + grading results (transcribed problems, the student’s answers, correct answers, score) | Grade the work and let the account holder review past grades | Available while the account is active for the account holder to revisit | Free plan: each graded paper is automatically deleted 90 days after upload, and only the 50 most recent are retained. Pro / Organization plans: retained while the account is active. Any graded paper can be deleted on demand from grading history, and all grader data is permanently deleted when the account is deleted. |
| Teacher-entered roster (student names, optional notes, optional student email for returning work, class/assignment labels) | Organize a teacher’s grades by student and class, and return marked work | Needed to group grades for class analytics | Retained while the account is active; permanently deleted when the account is deleted |
| Application error logs | Operational debugging and abuse investigation | Short-term reliability | 30 days |
| Resend email delivery metadata (sign-in codes, returned work) | Deliverability monitoring | Operational | 90 days |
Any category not listed above is not retained.
From students we do not collect: account credentials, ages, addresses, phone numbers, geolocation, audio, video, biometric identifiers, government IDs, cookies, IP addresses, or persistent identifiers used for cross-site tracking. Students have no accounts and never sign in. The only student information we hold is what a teacher or parent uploads or enters: the photo of the written work, which may carry a name, and the roster labels in the schedule above. We do not sell or license any student data, we do not use it for advertising, and we do not load advertising trackers on pages that display student work.
An account holder may, at any time, in the app or via email to hello@nudgelearn.app:
Where a school is the account holder, parent and student requests go through the school, since the school holds the education record. We complete our part within 15 business days of the school's request.
This policy is reviewed at least annually and whenever (a) data practices materially change, (b) a new regulation takes effect, or (c) a new collection category is introduced. The Founder approves revisions in writing.
