The app

BubbleGrade makes no network connections at all: no upload, no account, no analytics, no update check and no online licence check. Answer-sheet images, student responses, roll numbers and marks stay on your computer.

It stores, in the .bubblegrade folder of your Windows user profile: your settings (theme, window size), your licence key if you enter one, and an automatic copy of the exam you are working on (layout, answer key, marking scheme and the graded responses, with the file paths of the sheets you graded) so your work survives a restart. Files you save or export (PDF sheets, templates, exam files, Excel/CSV results) go only where you choose. Uninstalling leaves the .bubblegrade folder in place so a reinstall keeps your licence; delete it yourself to remove everything.

You are responsible for handling your students' data under the laws that apply to you, including the Digital Personal Data Protection Act, 2023 (India).

This website

The website uses no cookies, analytics, trackers or third-party fonts or scripts. If you switch between light and dark mode, that choice is stored only in your browser. Our hosting provider may keep standard server logs (such as IP address and pages requested) for security and operations.

Purchases

Payments are handled by our payment partner, which collects the billing details needed to process your order and calculate tax. We receive your name, email address and order details so we can issue your licence key and provide support. The name or email you give is written into your licence key.
