In short: With Google Play Services 26.26, rolled out to stable in late July 2026, Android gained a built-in feature that backs up documents — PDF, DOC, PPT, XLS, ZIP and even APK files from your Downloads folder — into a new "Android backups" folder on Google Drive. The good news: it is disabled by default and requires you to turn it on. The catch: it is easy to enable without realising what leaves your phone, and switching it off later does not delete the copies already uploaded. If you value control over where your files live, it is worth knowing exactly how this works.
What happened
Google has been building this quietly for almost a year. The first traces appeared in August 2025, it was officially mentioned in a Play System update in February 2026, and in late July 2026 it reached the stable version of Google Play Services 26.26. On Pixel devices a new Documents option now sits under Settings → Accounts and backup → Google backup. Turn it on, and Android starts uploading supported files from Downloads to a dedicated folder on your Google Drive.
This is a convenience feature, not a scandal — but any tool that silently copies documents off your device deserves a careful look, in the same spirit as our coverage of Android sharing age signals with apps. The question is not whether Google is doing something malicious; it is whether you know what is being copied, where it goes, and who can reach it.
What exactly gets copied
According to reporting on the feature, the backup covers common document and file types: PDF, DOC, PPT, XLS, ZIP "and other formats," including APK installer files sitting in your Downloads folder. The copies land in a folder called Android backups on Google Drive and count against your normal Drive storage quota — so a large backup can eat into free space and push you toward a paid plan.
Two limitations matter for privacy. First, this is a backup, not a two-way sync: a copy is made and then lives independently in the cloud. If you edit or delete the file on your phone, the cloud copy does not change. Second, and more importantly, turning the feature off does not remove files that were already uploaded — you have to go into Drive and delete them by hand. So a backup you enabled once and forgot can keep a snapshot of sensitive documents online indefinitely.
Why should you care where a document lives?
Your Downloads folder is often a junk drawer of the most sensitive things you handle: bank statements, contracts, scanned passports, medical results, pay slips, tax forms. On your phone, that data sits behind your device lock. Once it is copied to a cloud account, it inherits a different threat model: it is now reachable by anyone who gets into your Google account, it is subject to the provider's data policies and jurisdiction, and it becomes part of any future breach or legal request touching that account. None of that is unique to Google — it is the inherent trade-off of putting documents in any cloud. The point is to make that choice deliberately, file by file, rather than by leaving a broad switch on.
How to stay in control of your files
Check the setting. On Android, open Settings → Accounts and backup → Google backup and look for the Documents option. If you did not intend to back up your Downloads folder, leave it off — or turn it on only when you specifically want a copy.
Clean up what is already there. Because disabling the feature keeps old uploads, open Google Drive, find the Android backups folder, and delete anything you did not mean to store in the cloud.
Encrypt what is truly sensitive. For documents you must keep, a password-protected archive or an encrypted storage app means a cloud copy is far less useful to anyone who reaches it.
Protect the data in transit, too. Backups travel over whatever network your phone is on. On public Wi-Fi, a no-logs VPN encrypts that connection so no one on the same network can intercept files or credentials as they upload. LiMP VPN is a no-logs service for iOS and Android — see the plans, and follow more privacy news on our blog.
