Section 03
PWA and notifications
If you install BCSD as an app, the service worker may cache logos, scripts, styles, and pages so the home-screen app opens quickly. Push notification permission is optional and can be turned off in the browser or OS and in Notification settings. Sounds for alerts play only if you enable the sound channel.
Section 04
Third-party cookies
Some features are provided by other companies. Using them may allow those companies to set cookies or read identifiers:
- Google Sign-In — to authenticate with a Google account
- Facebook Login — to authenticate with a Facebook account (Facebook SDK may use cookies)
- Razorpay Checkout — to complete UPI, card, net-banking, or wallet payments
- Google Fonts — to load Inter and Raleway typefaces
Those companies process data under their own policies. We do not control their cookies. If you block them, social login or checkout may not work.
Section 05
Your choices
You can:
- Change language and theme from the header — this updates essential cookies/storage
- Sign out to clear session tokens on this device
- Revoke location, camera/microphone (for instructor video), and notification permissions in the browser
- Clear site data in your browser or installed PWA settings
- Use browser controls to block third-party cookies (checkout or social login may then fail)
Because most BCSD cookies are essential, there is no separate “optional analytics” toggle at this time. If we add non-essential analytics or advertising cookies later, we will update this page and, where required, ask for consent.
