Phones, websites and online services can collect information through account details, device permissions, cookies, advertising identifiers and activity logs. The amount and type of data vary by service. You cannot eliminate every form of collection, but a few routine checks can reduce unnecessary exposure.
Review permissions and connected accounts
On your phone, check which apps can access location, contacts, microphone, camera, photos and Bluetooth. Remove permissions that are not needed for the app’s core function. Review connected-app access in important accounts and revoke services you no longer use.
Strengthen account security
- Use a unique password for each important account, ideally managed with a reputable password manager.
- Enable multifactor authentication, preferably a passkey or security key where supported.
- Keep your operating system, browser and apps updated.
- Review recovery email addresses, phone numbers and active sessions.
Limit tracking where practical
Review browser privacy settings and block third-party cookies or cross-site tracking where the browser offers those controls. Understand that private browsing mainly limits what is stored locally; it does not make you invisible to websites, employers, schools or internet providers. Cookie choices also differ by site and jurisdiction.
Be cautious with data-removal promises
Data brokers may collect and compile public and commercial information. Some offer opt-out procedures, but removing one listing does not guarantee that information disappears everywhere or will not reappear. Read the provider’s policy and avoid handing sensitive identity documents to an unverified removal service.
Understand your rights
Privacy laws differ by state and country, and rights can depend on the type of data and organization involved. The Federal Trade Commission publishes consumer guidance about privacy, identity protection and online security at Consumer.ftc.gov. The FTC also explains its role in privacy and data security enforcement at FTC.gov.
Make privacy maintenance routine
Set a reminder every few months to review permissions, connected apps, account recovery settings and subscriptions. Prioritize accounts that contain financial, health or identity information. Privacy is not a one-time setting; it is an ongoing process of reducing unnecessary access and responding to changes.
