Your data stays on your device

GradLens is a fully client-side application. There is no backend server, no database, and no external API that receives your academic data. Everything you enter — module names, grades, credits, and semester plans — is stored exclusively in your browser's localStorage.

No account, no tracking

GradLens does not require an account or login of any kind. We do not set cookies, run analytics scripts, or track usage in any form. Your browsing behaviour within GradLens is entirely private.

Export & import system

When you export a PDF or JSON backup, that file is generated entirely in your browser and downloaded directly to your device. No data passes through any server during this process. JSON backups can be re-imported to restore your data across devices — this transfer happens directly between your devices with no intermediary.

Transcript parsing

Any transcript or file you import into GradLens is parsed fully in-browser using JavaScript. The file is never uploaded to or processed by an external server.

Feedback form

The in-app feedback form sends your message via Web3Forms directly to us. If you attach screenshots, they are uploaded to Cloudinary — a third-party image host — solely to include them in the feedback email; they are not used for any other purpose. If you choose to contact us directly via email, that communication is governed by your email provider's privacy policy.

Data deletion

You can delete all your data at any time from the Export & Backup page using the "Clear All Data" option. This permanently removes everything from your browser's local storage.

Summary

• Academic data is never collected or stored externally — only feedback messages (and optional screenshots) are transmitted when you choose to send them
• No cookies or tracking scripts
• No account or login required
• All processing happens in your browser
• You can export or delete your data at any time

The problem we saw

Most Singapore students manage their GPA through a frustrating combination of mental math, scattered spreadsheets, and digging through old semester emails. Existing GPA calculators either feel outdated, overly simplistic, or disconnected from how students actually think about their academic journey.

We found ourselves repeatedly asking the same questions: "What do I need next semester to hit a Merit?" or "Is it even realistic to recover from this semester?" There was no good tool to answer these clearly.

What GradLens is

GradLens is a modern, privacy-first GPA tracker and academic planner built specifically for Singapore students. It supports all major polytechnics, universities, and ITE — with accurate grading scales for each. You can also add your own custom school if yours isn't listed.

The goal is simple: give every student a single place to understand their standing, project their future, and plan smarter — without needing to create an account or trust a third party with their data.

Our core values

• Privacy first — your academic data never leaves your device
• Accessible to all — free, no login, works in any browser
• Simple by design — no clutter, no unnecessary features
• Built to grow with you — from first semester to graduation
• Educationally transparent — we explain how calculations work

Who made this

GradLens was built by Zeth Leong as a passion project for Singapore students. If you have ideas, spotted a bug, or just want to share feedback, the Contact & Feedback page is the best way to reach out.

What's next

GradLens is actively evolving. Planned improvements include richer export formats, PDF transcript import with auto-parsing, and smarter projection models. Feature requests from students directly shape what gets built next — so please do reach out.
