Privacy Policy

Last updated: June 8, 2026

PaperDeck is a free, open-source project built and run by Tim Huynh. It’s a reader for publicly available AI/ML research papers — you can browse them, save them to a library, and read them in-app with your place remembered. This page explains, in plain terms, what data the app stores and why. The full source code is on GitHub. Questions? Email me at timhuynhwork@gmail.com.

What PaperDeck stores

Your account.If you sign in with Google, the app receives your name, email address, and profile picture. If you use an email magic link instead, it’s just your email address. Sign-in and account records are handled by Supabase.
Your activity.The papers you save (“stars”) and your reading progress for each paper — scroll position, last-read and highlighted spots, reader type, and a status (to-read, reading, done).
Basic technical data. The host (Vercel) processes standard request info like IP address, browser type, and timestamps to serve and protect the site. One essential cookie keeps you signed in.

That’s it. No payment info, no ads, and no third-party analytics or tracking cookies.

How papers load

Paper text is fetched and cleaned up by the server from sources like arXiv and ar5iv. The figures and images inside a paper, though, load straight from those sources in your browser when you open the reader — so, like any external image on the web, those servers may see your IP address. Your PaperDeck account isn’t shared with them.

Who else touches your data

I don’t sell your data. It’s only handled by the services that keep PaperDeck running:

Supabase — database and sign-in; stores your account and activity.
Google— only if you choose “Continue with Google”, as your sign-in provider.
Vercel — hosting; serves the app and keeps request logs.

Deleting your data

Email me at timhuynhwork@gmail.com any time and I’ll delete your account along with your saved papers and reading progress. You can also ask for a copy of what’s stored about you.

Security

Everything is served over HTTPS, and per-user data is protected with row-level security so each account can only reach its own records.

A few more things

PaperDeck isn’t aimed at children under 13, and I don’t knowingly collect their data.
The services above may store data in the United States and other countries.
If this policy changes, I’ll update the date at the top. Material changes will be called out where reasonable.
