Privacy policy

BugHunt is a free tool for practising debugging. This policy describes exactly what happens to your data. It is written to be read, not to be skimmed past.

You can use most of it without an account

Browsing and solving challenges works without signing in. If you never create an account, we store nothing that identifies you — no account, no attempt history, no profile.

What we store if you create an account

• Your email address, so you can sign in and recover your account.
• Your name and profile picture, only if you sign in with Google and Google provides them. They are used to show who is signed in.
• The code you submit when you check a solution. This is what powers the attempt timeline, which lets you compare your attempts and see how your fix evolved.
• Your progress: which challenges you attempted, whether they passed, how many hints you used, and how long you took.
• Your bookmarks, and a username if you choose to create a public profile.

Your code runs in your browser

Python runs through WebAssembly and JavaScript runs in a sandboxed web worker — both inside your own browser tab. No server ever executes your code.

To be precise about the part people usually assume: when you press Run & Check while signed in, the code you submitted is saved to your account so your attempt history works. It is never run on our servers, and it is only ever visible to you — unless you turn on a public profile, which shows your solved count and badges but still never shows your code.

Analytics

We use Vercel Web Analytics to count page views and see which challenges people use. It is aggregate only: no cookies, no cross-site tracking, no advertising profile, and no attempt to identify individual visitors.

Who else touches your data

• Supabase — hosts the database and handles sign-in.
• Vercel — hosts the site and serves the pages.
• Google — only if you choose to sign in with Google, and only to confirm who you are.

We do not sell your data, share it with advertisers, or send you marketing email. There are no advertising or tracking cookies on this site. The only cookie is the one that keeps you signed in.

Deleting your account

Email devfixdaily@gmail.com from your registered address and we will delete your account and everything attached to it — attempts, submitted code, progress and bookmarks. Deletion cascades in the database, so nothing is left behind. You can also ask for a copy of your data.

Students and younger users

BugHunt is built for students. It is not directed at children under 13, and we do not knowingly collect their data. If you believe a child under 13 has created an account, email us and we will remove it.

Changes

If this policy changes in a way that affects you, the date at the top will change. See also the terms of use.
