We all know cookies as those tasty round things you dunk in your tea.
But on the internet? Cookies are less chocolate chip and more digital breadcrumb trail.
Every time you visit a website, little bits of data called cookies get dropped onto your device. Some are harmless (and even useful). Others? Not so much.
What Are Cookies, Really?
Cookies are small text files websites store in your browser.
They can:
• Remember your login details
• Keep items in your shopping basket
• Save your language or region preferences
Sounds handy, right? And it is… until marketers and trackers get involved.
The Good, the Bad, and the Creepy
- Good cookies – make life easier
• Example: you don’t have to log into Netflix every time. - Bad cookies – too clingy
• Example: they follow you across different sites, building a profile on what you click, like, and buy. - Creepy cookies – the stalkers
• Example: you look at shoes once, and now they’re haunting your Facebook feed for weeks.
Real Example
Ever searched for a holiday online, then suddenly every website you visit is showing you ads for flights and hotels?
That’s retargeting cookies at work. They’re not psychic — they’re just tracking you relentlessly.
Do This Today
- Check your browser settings
Most browsers let you block third-party cookies (the stalker type) while keeping useful ones. - Clear cookies regularly
It’s like spring cleaning — wipe out old trackers and start fresh. - Use “incognito/private” mode
Stops cookies being stored for that session (but doesn’t make you invisible online). - Look out for cookie banners
Don’t just click “Accept All” — choose “Manage” and turn off unnecessary ones. - Install privacy-friendly extensions
Tools like uBlock Origin or Privacy Badger can help block the worst offenders.
Key Takeaway
Cookies aren’t evil — but they’re not all sweet treats either. Some help your browsing, others quietly sell your habits to advertisers.
Knowing the difference gives you the power over what crumbs you leave behind.
At The Cyber Workshop, our Cyber Hygiene Workshop dives into things like cookies, trackers, and how to keep your online privacy without needing a computer science degree. Simple steps, big impact.
Till next time,
Remember: not all cookies go well with tea.
