Your digital footprint: how what you post can be used

Your digital footprint is the trail of information you leave online: posts, photos, comments, searches, accounts and even the apps you use. Some of it you create on purpose, and some is collected quietly. Employers, scammers and strangers can all use it, so it is worth managing.

What forms your footprint

• Social media posts, photos and tagged locations.
• Comments and reviews you write.
• Accounts you create on websites and apps.
• Information from online forms, such as your phone number and address.
• Data collected by apps and websites about your behaviour.

How it can be used against you

• Scammers use details such as your birthday, town, school and relatives' names to guess passwords or to make a believable trick.
• Thieves can learn when you are away from home from travel posts.
• Employers and clients may look at your profiles before they hire you.
• Fraudsters may copy your photos to create fake profiles.

How to check your footprint

Search for your name and phone number in a search engine and note what appears. Look at your own social media pages as a stranger would see them. Check old accounts you no longer use.

Reduce the risks

1. Review your privacy settings on each platform and choose the most restricted options you are comfortable with.
2. Think before you post. Avoid sharing your address, ID documents, boarding passes, bank details or children's school information.
3. Turn off location tagging for photos you share publicly.
4. Delete old accounts and posts you no longer need.
5. Use different emails for important accounts and for newsletters or casual sign-ups.
6. Be careful with quizzes and games that ask for personal facts, since they may collect answers to common security questions.

Build a positive footprint

Share useful knowledge, celebrate achievements and be respectful. A helpful, professional presence can open opportunities.

Teach younger family members

Children and teenagers may not realise that deleted posts can still be saved by others. Talk to them about privacy and respectful behaviour online.

A simple test

Before you post, ask: Would I be comfortable if my parents, my employer and a stranger saw this in five years? If not, think again.

Managing your footprint is not about hiding. It is about choosing what you share and with whom.
