Privacy is partly about limiting collection and partly about controlling who can reach information after it has been collected.
Review what you share
Provide only information needed for the task. Optional profile fields, public posts, location details, contact lists, and photo metadata can reveal more than expected. Privacy settings help, but copies and screenshots may persist.
Browser and application permissions
Websites and apps may request access to location, camera, microphone, notifications, files, or contacts. Grant access only when the feature requires it, and review permissions periodically. Remove extensions and apps you no longer use.
Private browsing reduces local history but does not make activity anonymous.
Using public Wi-Fi
Confirm the network name with the venue; attackers can create look-alike networks. Prefer encrypted websites, keep file sharing off, and avoid sensitive account changes on an untrusted shared network when a safer connection is available.
Mobile data or a personal hotspot can be preferable for banking or confidential work. A VPN can encrypt traffic to the VPN provider, but it does not make unsafe sites trustworthy.
Shared and public computers
Avoid saving passwords or payment details. Sign out fully, close the browser, and do not leave downloaded files behind. For highly sensitive work, use a trusted personal device instead.
