What’s the best way to limit the data a company can gather on you? Use privacy settings to limit their reach.
Personalized advertising: Microsoft uses your searches and purchase history to serve you with customized ads. You can turn this off in the privacy dashboard.
Select Privacy. Next, scroll down to Personalized ad settings and click on Review ad settings. Toggle the slider next to See ads that interest you to the left to disable it.
Accessing diagnostics from other apps: Unless you turn it off, Microsoft collects diagnostic data from apps you use “to help improve our products and make them work better.”
To delete the data, select Privacy. Scroll down and click the App and service activity tab.
Click Clear all app and service activity to delete it.
Access to your location: There might be instances where your location is essential for apps and services to work correctly. But you don’t want Microsoft always to know where you are located.
Select Privacy. Click the Location activity tab. This displays all the places where Microsoft tracked you. Click Clear location history, then Clear to remove the data.
Browsing history: If Microsoft’s Bing is your preferred search engine, you can delete your data through the privacy dashboard.
While in the Privacy dashboard, click Browsing history and delete the data by clicking Clear all browsing activity.
Search History: Bing and Cortana use your search history for more personalized results.
Open the Search history tab in the Privacy dashboard and click Clear all search history, then Clear to remove the data.
Back to Start
You can also manage the data that Microsoft has right from your desktop.
Go to Start > Settings > Privacy & security.
Select General.
Toggle the switch to the left under Let apps show me personalized ads by using my advertising ID. Review the other options and change whatever you like.
What about Apple Mac users?
You use an Apple ID to log in on a Mac (or iPhone or iPad). When you create one, Apple says it might collect any of the following:
Your email, devices (and info on them like serial numbers), account status and age.
Contact info like your name, physical address and phone number.
Your billing address, bank details or card info.
Your browsing history, search history, product interaction, crash data, performance and other diagnostic data and other usage data.
Health info relating to physical or mental health or conditions.
Salary, income and assets information if you provide it, and information related to Apple-branded financial offerings.
Want a copy of what they know?
From your computer, go to privacy.apple.com and sign in with your Apple ID. You may have to complete two-factor authentication.
Under Get a copy of your data, select Request a copy of your data.
Choose what you’d like to download from the list or Select all. Note that downloading your iCloud files, Mail and Photos will take a long time.
Click Continue.
Choose your preferred file size. Apple will divide your data into folders that size or smaller.
Select Complete request.
You’ll get an email when your data is ready. The process takes up to 7 days, and you will need to verify again that you are the one who requested the info.
