How to Limit Ad Tracking on Your Phone
How to Limit Ad Tracking on Your Phone
Your phone is a powerful tracking device for advertisers — apps and services track your activity, location, and interests to build a profile for targeted advertising. Fortunately, your phone includes settings to limit this ad tracking. Adjusting them reduces how much you are tracked and profiled. This guide explains how to limit ad tracking on your phone, in plain terms.
How Your Phone Tracks You for Ads
Several mechanisms enable ad tracking on phones:
Advertising identifier: Your phone has an advertising ID — a unique identifier used to track your activity across apps for advertising. This is a central tool for ad tracking.
App tracking: Apps can track your activity, and some track you across other apps and websites for advertising.
Location tracking: Apps and services can track your location, which is used for advertising and profiling.
Data collection: Apps collect data about your usage and interests, contributing to your advertising profile.
The result: These combine to build a detailed profile of you for targeted advertising — which the settings below help limit.
Reset or Limit Your Advertising ID
Your advertising ID is a key lever:
Reset your advertising ID: Resetting your advertising ID periodically breaks the continuity of tracking tied to it, making it harder to build a long-term profile. You can reset it in your phone's privacy/ads settings.
Limit or delete the advertising ID: Modern phones let you limit ad tracking or even remove/disable the advertising ID entirely, significantly reducing identifier-based ad tracking. Use this option where available — it is one of the most impactful steps.
Opt out of personalized ads: Disable personalized or interest-based advertising in your phone's settings, reducing ad targeting based on your profile.
Control App Tracking
Limit how apps track you:
Use app tracking controls: Modern phones offer controls over apps tracking you across other apps and websites. Use these to deny or limit cross-app tracking — a powerful privacy control.
Deny tracking requests: When apps request permission to track you, deny it unless you have a reason to allow it.
Review and limit app permissions: Review app permissions (especially location, but also others) and revoke what apps do not need, limiting the data they collect for tracking.
Limit Location Tracking
Location is sensitive and valuable for tracking:
Review location permissions: Review which apps have location access and limit it — granting location only to apps that need it, and only while using the app rather than always.
Limit precise location: Where possible, give apps approximate rather than precise location if they do not need precision.
Disable location when not needed: Turn off location services for apps that do not need it.
Adjust System and Account Privacy Settings
Broader settings reduce tracking:
Review privacy settings: Go through your phone's privacy settings and disable data collection and ad personalization options you are not comfortable with.
Adjust account ad settings: Adjust the ad and data settings on your major accounts (which often tie into phone tracking), limiting personalization.
Limit diagnostic data sharing: Limit sharing of usage and diagnostic data where offered.
Combine with Broader Privacy Practices
Phone ad-tracking settings work alongside other measures:
Use privacy-focused apps and browsers: Privacy-focused browsers and apps reduce tracking beyond the system settings.
Limit cross-device tracking: Your phone tracking ties into cross-device tracking; reducing identifiers and tracking on all devices helps.
Share less data: Using temporary email like Temp90 for app signups and sharing less data limits the profile built about you.
Combine measures: Limiting ad tracking on your phone is one layer; combining it with broader privacy practices provides more comprehensive protection.
Frequently Asked Questions
How do I limit ad tracking on my phone?
Start with your advertising identifier: reset it periodically, and where your phone allows, limit ad tracking or remove/disable the advertising ID entirely — one of the most impactful steps — and opt out of personalized ads.

What is the advertising ID and should I reset it?

Yes, you should reset it periodically, which breaks the continuity of tracking tied to it and makes it harder to build a long-term profile of you. Even better, modern phones let you limit ad tracking or remove/disable the advertising ID entirely, which significantly reduces identifier-based ad tracking — one of the most impactful steps you can take. You can find these options in your phone's privacy or ads settings.
How do I stop apps from tracking me across other apps?
Modern phones offer app tracking controls that let you deny or limit apps tracking you across other apps and websites — use these, as they are a powerful privacy control. When an app requests permission to track you, deny it unless you have a specific reason to allow it. Additionally, review and limit app permissions (especially location, but others too), revoking access apps do not need, which limits the data they can collect for tracking. Combining app tracking controls with limited permissions significantly reduces how apps track you across your phone.
Conclusion
Your phone is a powerful tracking device for advertisers, with apps and services tracking your activity, location, and interests to build an advertising profile — but your phone includes settings to limit this. The advertising identifier is a key lever: reset it periodically, and where possible limit ad tracking or remove/disable the advertising ID entirely (one of the most impactful steps), and opt out of personalized ads. Control app tracking using your phone's controls to deny or limit cross-app tracking, deny tracking requests, and review and limit app permissions. Limit location tracking by granting location only to apps that need it, only while using them, and using approximate rather than precise location where possible. Adjust your phone's privacy settings and your accounts' ad settings to reduce data collection and personalization. Since phone ad-tracking settings are one layer, combine them with privacy-focused apps and browsers, reducing cross-device tracking, and sharing less data (using temporary email like Temp90 for app signups). By adjusting these settings on your phone, you can significantly reduce how much you are tracked and profiled for advertising.
