Have you seen products on Instagram and realised that you had previously searched for them on Google? This happens because companies use free apps and cookies to collect your data and then sell it to advertisers.
They are only too glad to know what you are interested in at the moment, in order to then hit you with targeted advertising and influence (often subconsciously) your buying behaviour and opinions.
It’s wrong to think that nobody is interested in your data, because all data is interesting. All data is collected, analysed and sold.
It’s not only in real life that we leave traces behind us; it happens on the internet too. It is essential to learn how to handle data and devices properly.
- Choose the right settings on your device and think carefully about which apps and websites you allow to access your data (e.g. location).
- If you want to prevent things like airline websites from showing you more expensive fares the next time you visit, delete your cookies regularly.
- Be aware what data you share where, when and with whom.
