🟢 Introduction

Your personal information is valuable. From shopping habits to your location and private conversations, everything can be collected, sold, or even stolen.
This course helps you take back control of your privacy—without needing any technical skills.

📘 1. Why Privacy Matters

Most people underestimate how much data they share.
Even basic actions—browsing a website, installing an app, or using Wi-Fi—can leave a trail.

Hackers, advertisers, and even public databases may collect this data.
If misused, it can lead to:

Identity theft
Financial fraud
Targeted scams
Personal or professional reputation damage

Protecting your privacy protects your freedom.

📘 2. What Is Your Digital Footprint?

Your digital footprint includes everything you do online:

Websites you visit
Purchases you make
Posts you like or share
Emails and chats
Location data from your phone

The more information exposed, the easier it becomes for others to profile or attack you.

📘 3. Clean Up Your Online Presence

Start by reducing your online exposure:

Delete old, unused accounts
Avoid using your full name or birthdate publicly
Search for your own name to see what’s already exposed
Use a search engine like DuckDuckGo instead of Google for private searches

These steps help limit the amount of personal data linked to you.

📘 4. Secure Your Social Media

Social media is one of the biggest privacy risks.

Set your profiles to private
Don’t post your location, daily routines, or travel plans
Avoid tagging yourself in real-time events
Limit who can message or tag you

Think before you post—once shared, it’s often permanent.

📘 5. Lock Down Your Devices

Keep your phone, laptop, and tablet protected:

Use strong, unique passwords
Turn on full-disk encryption (available on most devices)
Keep your software and operating system up to date
Set auto-lock when idle

If your device is lost or stolen, this prevents data exposure.

📘 6. Review App Permissions

Apps often request more access than they need.

Check your device settings and:

Revoke location access for apps that don’t require it
Disable microphone and camera permissions unless necessary
Block background data collection

Only allow access that makes sense for the app’s purpose.

📘 7. Protect Your Browsing

Make your browser more private:

Use incognito/private mode for sensitive searches
Install trusted extensions like uBlock Origin or Privacy Badger
Disable third-party cookies in settings
Log out of websites when you’re done

Your browser is a window into your life. Keep it clean.

📘 8. Practice Smart Sharing Habits

Avoid oversharing:

Don’t publish your home address, phone number, or ID number
Think twice before clicking on “free giveaways” that ask for too much personal info
Always read the privacy policy before giving away data
Use anonymous or secondary emails for untrusted websites

Once data is collected, it’s often shared or sold.

📘 9. Use Two-Factor Authentication (2FA)

Passwords alone are not enough.
2FA adds an extra layer of security by asking you to verify your identity with a second method:

SMS code
Email confirmation
Authenticator app (more secure) like Google Authenticator or Microsoft Authenticator

This protects your accounts even if someone steals your password.

📘 10. Summary: Quick Wins for Privacy

Start with these simple actions today:

Use a VPN on public Wi-Fi
Install a password manager
Review your phone and app permissions
Use private search engines
Turn off location tracking where unnecessary
Enable 2FA on all important accounts

Protecting your digital life doesn’t require expensive tools—just awareness and good habits.
