Most people keep their important documents in Google Drive because that’s where everything else already lives. The lease, a scan of the passport, a photo of the medical aid card, the folder called “Admin” that nobody else in the house can find. It works well, right up until the day it matters.
So, is Google Drive safe for important documents? Against the threats it was designed to handle, yes. The useful answer needs a second question attached: safe from whom?
What Google Drive genuinely protects you from
The engineering here is serious, and it’s worth saying so plainly. Your files are encrypted while they travel to Google and while they sit on Google’s disks. Google’s own Workspace encryption whitepaper describes stored content encrypted with AES using a 128-bit or stronger key.
Turn on 2-Step Verification and Drive handles the ordinary disasters well: a stolen laptop, a hard drive that dies the week before you needed the file. Deleted files sit in the bin for a while, and older versions can be restored. A shoebox on top of the wardrobe does none of that.
The part most people miss is who holds the keys
Google’s cloud security documentation says it plainly: Google owns and manages the keys used in its default encryption at rest. Your files are locked, and Google holds the key to the lock.
That single fact decides everything downstream:
- Google can technically read what’s in your Drive. Internal access is controlled and audited, but the capability exists by design
- Google responds to lawful requests from governments and courts. Its policy page explains how, and the Transparency Report publishes the volumes twice a year
- If someone gets into your Google account, they get your documents. Encryption at rest doesn’t help here, because from Google’s side that request looks like you
Google does offer client-side encryption, where the provider can’t read the content. The help page is clear that you need a Workspace account and an administrator who has switched it on. On a personal Gmail address, it isn’t available to you.
Sharing is where it usually goes wrong
Most documents escape from Drive by being shared once and then forgotten about.
A folder set to “anyone with the link” three years ago, when you were sending a bank statement to a landlord. The bookkeeper from a business you’ve since closed, still on the list. A tax folder shared with a sibling who has it synced to a laptop the whole family uses. No amount of AES fixes any of that, because the system is doing exactly what it was told to do.
Go and look at the sharing settings on your most sensitive folder now. Most people find at least one thing they’d forgotten about.
What happens when you’re not there to log in
Google’s Inactive Account Manager lets you nominate up to 10 trusted contacts and release selected data to them after a set period of inactivity. It’s a good tool and more people should set it up. Two limits are worth knowing.
Google detects activity from sign-ins, My Activity, Gmail usage and Android check-ins, so a phone that stays signed in can keep an account looking alive long after its owner isn’t. And if you set nothing up at all, Google reserves the right to delete an account that’s been inactive for two years, along with its data. Families can request access to a deceased person’s account, though that’s a review with no guaranteed outcome.
Even when it works, what arrives is a download of your Google data. Useful, though nobody inherits the knowledge of which policy number matters or where the original title deed physically sits.
Where an encrypted vault works differently
Vaultneur was built for the smaller set of records where “Google can read this” is the wrong answer.
Everything is encrypted on your phone before it goes anywhere. Each file gets its own AES-256-GCM data encryption key, and that key is wrapped by a vault key derived from your password with PBKDF2-SHA256, held in the iOS Keychain or Android Keystore behind Face ID or a fingerprint. That’s on-device envelope encryption, and it’s written up properly in the Vaultneur security paper. Because of how it’s built, Vaultneur holds no key that can open your vault, so a subpoena served on us produces ciphertext.
The trade is real, and you should weigh it before you commit. Your password is never sent to us, which means we can’t reset it the way Google can. Vaultneur issues a 24-word recovery key at setup, and that phrase is the only other way in. Google can get you back into your account after a bad week. We can only get you back in if you kept those words somewhere you’ll actually find them, which makes where you keep them part of the plan rather than an afterthought.
For handover, Family Vault shares selected categories with people you choose. Keys are delivered to their device rather than to us, and you can revoke access at any time.
A reasonable setup for most people
You don’t have to pick one tool. Use both, deliberately:
- Keep working documents and anything you collaborate on in Drive. That’s what it’s good at
- Audit your sharing links, and turn on 2-Step Verification if you haven’t already
- Set up Inactive Account Manager, or decide against it knowingly rather than by default
- Move the handful of records that would be damaging in the wrong hands into an encrypted digital vault: ID documents, medical history, financial account details, crypto wallet keys, logins
- Write a short Legacy Binder telling one trusted person what exists and where to start. The documents are only half of it
Google Drive works well as a filing cabinet. A safe is a different piece of furniture, and a few of your documents belong in one rather than the other. Working out which is which is most of the job.
