The comparison
| Gemini (Free/Plus/Pro/Ultra) | Ask Safely | |
|---|---|---|
| Trains on your data | Yes, by default. Opt-out by turning off "Keep Activity" at myactivity.google.com. Forward-looking only. Data already used for training can't be removed. | Never. Two layers: AWS Bedrock's contract prohibits training on customer data, and Ask Safely adds its own no-training policy on top. |
| Human review | Yes. Google states human reviewers "read, annotate, and process your Gemini Apps conversations." They warn users: "don't enter confidential information in your conversations or any data you wouldn't want a reviewer to see." | No human review of conversations. |
| How long chats are kept | Conversations selected for human review: up to 3 years, stored disconnected from your account. Unreviewed conversations with Keep Activity on: up to 18 months by default. Even with Keep Activity off, conversations are held up to 72 hours. | Auto-deletes on a timer you choose: 8 hours (default), 7 days, or 30 days. When the timer hits zero, the conversation is gone. |
| Memory | Two layers: "Saved Info" (explicit facts you enter) and "Personal context" (automatic, on by default, learns from past chats). Can also connect to Gmail, Calendar, Drive, YouTube, Photos, and Search history for deeper personalization. | Off by default. Every fact visible, editable, deletable. Declined facts leave no trace. No connection to external accounts. |
| Cross-product data use | Gemini sits inside your Google Account. If you connect apps, Gemini can read your email, calendar, and files. Google warns that connected data "may relate to topics you find sensitive, like race, religion, and health" and becomes subject to the same review and retention terms as chat data. | Isolated. Your conversations don't feed into any other product or service. |
| Encryption | AES-256 at rest (storage layer), TLS in transit. Standard Google Cloud infrastructure encryption. No per-user keys on consumer tiers. | AES-256-GCM with per-user data encryption keys, KMS envelope encryption. The memory system is fail-closed and refuses to run without its encryption key. |
| Advertising | Google says Gemini chats aren't currently used to show you ads. But Gemini lives inside a Google Account where Ads Personalization draws on data across all Google services. The separation is a policy choice, not an architectural boundary. | No advertising. No advertising identifiers. No IDFA, GAID, or ad-tech trackers. Subscriptions are the only revenue. |
| Price | Free / ~$5-8 (Plus) / $20 (Pro) / $100-250 (Ultra). Workspace tiers: $7-55/seat/mo. Consumer tiers don't opt you out of training or human review. | Free (Essential) / $12/mo or $120/yr (Expert). Auto-delete and no-training included on the free tier. |
What Gemini actually does with your data
Google is upfront about this, to their credit. It's in their Gemini Apps Privacy Notice. Most people just don't read it.
Human reviewers read your conversations. Google selects a random sample of Gemini conversations for human review. Reviewers "read, annotate, and process" them. Reviewed conversations are stored for up to three years, disconnected from your Google Account but with metadata attached. You can't delete a conversation that's been selected for review. Google's privacy notice says it plainly: "Human review is a necessary step in building products like Gemini Apps."
Training is on by default, and opting out doesn't undo anything. Gemini uses your conversations to improve its models unless you turn off "Keep Activity" at myactivity.google.com. But the opt-out is forward-looking only. Conversations already used for training stay in the training corpus. There is no mechanism to remove them after the fact.
Gemini can see your entire Google life. Through Connected Apps, Gemini can access Gmail, Calendar, Drive, Photos, YouTube, Search, and Contacts. This is marketed as convenience, and for many people it is. But Google's own privacy notice warns that connected data "may relate to topics you find sensitive, like race, religion, and health" and that it becomes subject to the same review and retention terms as your chat data. The assistant reading your email and the assistant training on your conversations are the same assistant.
The ad infrastructure is right there. Google says Gemini conversations aren't "currently used" to show you ads. But Gemini lives inside the same Google Account that powers Ads Personalization, which draws on data across all Google services. The wall between your Gemini chats and Google's advertising business is a policy decision. It is not an architectural separation. Policies change with a terms update.
What Ask Safely does differently
Ask Safely runs on Anthropic's Claude models but wraps them in a different data architecture.
No human review. Nobody at Ask Safely reads your conversations. Not a random sample. Not for quality assurance. Not for training. There is no human review process because there is no reason to have one when you don't train on user data.
Auto-delete, not 18-month default retention. You pick the timer at signup: 8 hours, 7 days, or 30 days. A MongoDB TTL index handles deletion at the database level. When the timer expires, the conversation is permanently removed. Google keeps unreviewed conversations for up to 18 months by default. Even with "Keep Activity" turned off, conversations are held for up to 72 hours. Ask Safely's default is 8 hours, and it means what it says.
No cross-product data use. Ask Safely is a standalone product. Your conversations don't feed into an email service, a search engine, a calendar, or an advertising platform. There is no broader ecosystem for your data to leak into.
Where Gemini is better
Gemini has real advantages. Being honest about them makes the rest of this comparison worth trusting.
Google ecosystem integration. If you live in Gmail, Calendar, and Drive, Gemini can work across all of them. It can draft replies from your email context, pull facts from your documents, and check your schedule. Ask Safely is standalone and doesn't connect to external services.
Free tier generosity. Gemini's free tier offers higher usage caps and access to a broad model range. Ask Safely's free Essential tier is more limited in daily usage.
Workspace and Enterprise. Google Workspace and Gemini for Google Cloud offer genuine enterprise privacy protections: data processing agreements, region-specific data residency, and SOC 2/ISO compliance. Ask Safely's SOC 2 is expected early 2027.
Multimodal capabilities. Gemini handles video understanding and image generation natively. Ask Safely doesn't generate images or process video.
The bottom line
If you're deep in the Google ecosystem and you trust Google to keep its policy wall between Gemini and its advertising business, Gemini is a powerful tool. The integration with Gmail, Calendar, and Drive is genuinely useful, and the enterprise tiers offer real privacy protections.
If you'd rather your AI conversations not live inside the same company that runs your email, your search history, and the world's largest advertising business, Ask Safely is built differently. No training, no human review, no cross-product data use. Same Claude models. Different rules about what happens to your words after you say them.
