Line by line
The lines that matter most, worst first.
Firebase analytics can take advertising and device IDs from people who use apps built with it.
Read the exact line
Privacy policy
“Google Analytics for Firebase: Can collect a user's mobile ad ID, IDfV ID (iOS) or Android ID, instance ID, and Analytics app instance ID for analytics purposes”
For example, an app using Firebase Analytics could send your phone’s ad ID to Google for usage stats.

Read the exact line
Privacy policy
“ML Kit for Firebase: Can collect a user's uploaded images and instance ID for use with Vision API”
For example, a photo you snap in the app could be sent for image recognition.
Firebase apps that use AdMob can use cookies for targeted ads.
Read the exact line
Privacy policy
“If you use a targeted advertising service such as Google AdMob, you'll need to disclose the cookies you use for targeted advertising.”
For example, ads in the app might follow you based on an advertising ID.

“Google requires that you notify your users about how to opt out of Google Analytics for Firebase.”
For example, an app might put an analytics off switch in Privacy Settings.
The article tells developers to describe deletion if they offer it; it does not give you a delete button here.
Read the exact line
Privacy policy
“If you offer your users a means by which to access, modify, or delete their data, you must explain this process in your Privacy Policy.”
For example, this page does not say how to delete an account with Firebase itself.
The blog itself shows a last-updated date of 30 April 2026.
Read the exact line
Privacy policy
“You should provide you Privacy Policy's "effective date," meaning the date you published the most recent version.”
For example, you can see when this article was last changed, but that is not Firebase’s contract date.
This page is a guide, not the legal terms you agree to with Google or Firebase.

Privacy policy
“This article is not a substitute for professional legal advice. This article does not create an attorney-client relationship, nor is it a solicitation to offer legal advice.”
For example, signing up for Firebase is governed by Google’s own terms, which are not in this document.
Words to know
Legal words from the lines above, in plain English.
- personal data
- Any information that is about you or can be linked to you, from your name to your phone's ID. For example, your email, your IP address and the list of apps on your phone are all personal data.
- third parties
- Any company or person other than you and the app, such as advertisers, partners or analytics firms. For example, an analytics company that receives a record of every screen you tap is a third party.
- opt out
- Something is on by default and stays on until you find the setting and turn it off. For example, your chats may be used for training unless you go into settings and switch it off.
- device identifiers
- Codes that single out your phone or computer, used to recognise you across apps and sites. For example, the advertising ID on your phone lets two unrelated apps know they are seeing the same person.
- targeted advertising
- Ads chosen for you based on what you have done across other apps and websites, not just this one. For example, you look at shoes in one app and see shoe ads in a totally different app the next day.
- cookies
- Small files a website saves on your device so it can recognise you and remember what you did. For example, a cookie keeps you logged in and can also tell an ad company which sites you visited.
