Google (Docs / Drive / Workspace)

The host behind a shared Google Doc — and the most split-by-tier company on this list. What matters most is which Google you're on. A paid Workspace account (your org's @yourorg.org email) gets a written promise: no ads, no AI training on your files. A free personal @gmail.com account gets the no-ads promise too, but its AI assistant (Gemini) is a different story.

Bottom line for sharing a doc: usually fine. The doc you share is the thing you meant to hand out, and on either account type Google doesn't mine your Docs/Drive files for ads. The one knob worth knowing is on the personal-account Gemini assistant, named below.

Last verified: 2026-06-07 · Confidence: high on the Workspace no-ads/no-training stance, the consumer Gemini toggle, and the data-regions split (all from Google's own docs); exact consumer-side AI-training language is the soft spot.

Does it train AI on what you put in?

The honest answer depends entirely on account type — and on whether you use Google's Gemini AI assistant at all. Your Docs and Drive files themselves are not scanned for ads on either tier. [confirmed]

  • Paid Workspace account: no training, by contract. Google states "Your interactions with Google Workspace with Gemini stay within your organization... Submissions aren't used to train models and are never reviewed by humans," and "None of your content is used for model training outside of your domain without permission." This covers Gmail, Drive, Docs, and the Gemini side panel in them. [confirmed]
  • Free personal account, files at rest: not used for ads. Google's commitment is blunt: "We don't use information in apps where you primarily store personal content — including Google Docs, Sheets, Slides, and Vids — for advertising purposes, period." [confirmed]
  • Free personal account, the Gemini assistant: yes by default, and switchable. If you chat with the consumer Gemini app, "a subset of chats are reviewed by human reviewers... to help improve Google services," including model training. The Gemini Apps Activity setting is on by default (turned off by default in the EEA/UK), so flip it off if you care. [confirmed]

If you only share docs and never open the Gemini assistant, the third point doesn't apply to you.

Turn the consumer Gemini training off

One setting, ~30 sec — personal accounts only (Workspace already doesn't train):

  1. Go to Gemini Apps Activity (or My Account → Data & privacy → Gemini Apps Activity).
  2. Find Keep Activity and turn it off.

Future chats then aren't sent for human review or used to train Google's AI. [confirmed] One catch: even off, chats are held 72 hours for safety; anything already human-reviewed is kept up to 3 years. [confirmed]

Keeping and deleting your data

  • Your files are yours. Google states plainly: "Google Workspace customers own their customer data, not Google." On personal accounts you likewise keep ownership of your Docs and Drive files. [confirmed]
  • Delete and it's gone — within 180 days. Google commits that "if customers delete their data, we commit to deleting it from our systems within 180 days," backups included. That's slower than the ~30-day window most other hosts here quote, but it is a firm promise. [confirmed]
  • Anything someone already copied is theirs to keep. A collaborator who downloaded your doc, or made their own copy, keeps it — deleting your original never reaches their copy. [estimate]

What a paid/Workspace tier changes

If your data is regulated (health, personal, anything under a grant's data terms), a paid Workspace account is the tier that earns the guarantees a compliance review wants:

  • A real data agreement (DPA). The Cloud Data Processing Addendum makes Google your processor, not controller, with Standard Contractual Clauses for cross-border transfer. [confirmed]
  • No-training in writing, plus admin controls — org-wide policies, audit, retention rules for Gemini conversation history (3 months / 18 months / 3 years / indefinite). [confirmed]
  • Pick where your data lives (next section). [confirmed]

For an individual sharing a doc, a syllabus, or a public form, a free Gmail account is genuinely fine — the Workspace extras are for orgs handling regulated data.

Where your data is stored (EU / UK / US)

  • Free/personal accounts: no region choice. Google stores consumer data across its global infrastructure including the US, with no setting to pin a location. Under GDPR that's a US transfer — usually fine, but name it if a grant or DPA restricts where data may sit. [confirmed]
  • Choosing Europe is a paid feature. Workspace data regions let an org pin covered data at rest (Gmail, Drive, Docs, Calendar, and more) to the US or Europe — available on Business Standard and above (Business/Enterprise/Education Standard and Plus, Frontline). It runs through the Admin console, not self-serve on a personal account. [confirmed]
  • No UK-specific region as of 2026-06 — only "United States," "Europe," or "No preference." The EU region is the closest GDPR-aligned option. [confirmed]
