The short version
- You can use every challenge without an account. Your progress is then stored only in your browser.
- Challenges run entirely in your browser. The commands you type are never sent to us.
- Resumes checked with the ATS checker are analysed in your browser and never uploaded.
- We don't sell your data and we don't show ads.
If you sign in with Google
Sign-in is optional. If you use it, we receive your name, email address and profile picture from Google, and we store them together with your challenge progress (solved challenges, XP, streak and badges) so it syncs across devices. Accounts and progress are stored with our database provider, Supabase. You can ask us to delete your account and data at any time (see Contact).
Analytics
We use PostHog to understand how the site is used: pages viewed, challenges started and solved, and which link brought you here. This helps us decide which challenges to build next. If you sign in, these events are linked to your account.
Your rights
Under India's Digital Personal Data Protection Act, 2023 you can ask to access, correct or delete your data. Message us and we'll handle it within 30 days. You can also clear your local progress any time by clearing this site's data in your browser.
