Cookies and Browser Cleanup

Learn what cookies do, how websites track you, and how to safely clear your browser history without deleting your saved passwords.

What are cookies? (Explained simply)

Imagine visiting a coat-check room. You hand over your coat, and the attendant gives you a small numbered ticket. When you return later, you show that ticket, and they hand your exact coat right back. An internet cookie is that small ticket[cite: 9]!

Important Fact: Cookies are not computer viruses, malware, or programs[cite: 9]. They are tiny text files stored by your browser (such as Chrome, Safari, or Edge) to help websites remember useful preferences, shopping items, and logins[cite: 9].
1. You Visit a Site You browse an online store or sign into your school portal[cite: 9].
→
2. Ticket Saved The website gives your browser a small token remembering your session[cite: 9].
→
3. Welcome Back Next time you open the site, you remain logged in and your cart stays full[cite: 9].

Helpful cookies vs tracking cookies

Not all cookies do the same job. Here is how to understand the difference between cookies that assist your session and cookies that track your habits[cite: 9]:

First-Party Cookies (Helpful)

Created by: The actual website you are visiting (like YouTube or Amazon)[cite: 9].

What they do: Keep you signed into your profile, remember your preferred language or dark mode theme, and keep items inside your basket as you browse different pages[cite: 9].

Third-Party Cookies (Tracking)

Created by: Outside advertising agencies and tracking networks[cite: 9].

What they do: Follow you from one site to another to see what shoes, games, or tech gadgets you look at, using your browsing history to show targeted adverts across the web[cite: 9].

The truth about Incognito / Private Browsing

Many people believe opening an Incognito or Private Browsing window makes them a ghost who cannot be seen by anyone. That is a myth[cite: 9]! Here is what private mode actually does:

What Private Mode DOES do

1. Automatically deletes all cookies, browsing history, and temporary files the exact moment you close the private window[cite: 9].

2. Prevents family members or friends who use the same computer from seeing what websites you visited[cite: 9].

3. Allows you to sign into two different email accounts at the exact same time without logging out of the first one.

What Private Mode DOES NOT do

1. It does not hide your internet activity from your school network, employer, or internet service provider (BT, Virgin, Sky)[cite: 9].

2. It does not stop websites from knowing your approximate city or location.

3. It does not protect you if you download infected files or enter passwords into fake scam links.

Double Check Before Deleting: Never wipe your passwords! When clearing browsing history, always look closely at the checkboxes[cite: 9]. If you tick "Saved Passwords", your browser will delete all your memorized logins[cite: 9]! Use a dedicated password manager (like Bitwarden, Google Password Manager, or Apple Keychain) so your credentials remain protected even after a browser cleanup[cite: 9].

Browser cleanup checklist

  • Clear cookies once a month to remove accumulated tracking networks[cite: 9].
  • Never clear "Saved passwords" or "Autofill form data" during routine cleanups[cite: 9].
  • Be prepared to sign back into common accounts with your two-factor authenticator app after clearing[cite: 9].
  • Use Private / Incognito browsing when booking flights, shopping for surprise presents, or using shared computers[cite: 9].
  • Turn on "Block Third-Party Cookies" inside your browser settings to stop advertising trackers automatically.
