Intro:
Hey guys i did a deep research using Gemini 2.5 advanced on the privacy policies of google and Open Ai and here is the quick summery of it.

If you're paying for ChatGPT Plus or Google Gemini Advanced, you'd expect better privacy. But after combing through their official policies, help docs, and privacy portals—what I found was deeply concerning. This guide explains how your data is being used, how to stop it, and the shocking trade-offs and loopholes both companies have built into their systems.

Section I: TL;DR – Key Privacy Concerns at a Glance

Section II: ChatGPT Plus (OpenAI) – What's Really Going On

A. By Default, Your Conversations Train the Model

• Unless you explicitly opt out, OpenAI uses your conversations, uploads, and feedback to train its AI.

• Applies even to paid ChatGPT Plus users.

• Only business tiers (API, Team, Enterprise, Edu) have guaranteed no-training defaults.

B. Opt-Out Options (Some Hidden)

1. Best Method: Go to privacy.openai.com → “Make a Privacy Request” → Select “do not train on my content”

   • Keeps chat history + disables training

2. Quick Toggle (may differ by user interface):

   • "Improve the model for everyone" = disables training, keeps history

   • "Chat History & Training" = disables both training and chat history

3. Temporary Chat: Manually start one per session. No training, no history, but OpenAI still keeps it for 30 days.

4. Memory Danger Zone:

   • ChatGPT remembers info across sessions.

   • Turn OFF in Settings → Personalization > Memory.

   • You must delete saved memories manually—they persist beyond chat deletion.

C. Human Review Risk

• Even after opting out of training, OpenAI may review your chats:

  • For abuse, policy violations, or legal reasons

  • Possibly via third-party contractors

• Only training-related reviews are affected by opt-outs, not safety/legal access

Section III: Google Gemini Advanced – Cleaner Controls, But Hidden Costs

A. Training & Review Happen by Default

• "Gemini Apps Activity" is ON by default

  • Your chats, locations, feedback, and more may be:

    • Used for training

    • Sent to human reviewers

• Google explicitly warns you: don’t share anything private or sensitive.

B. Opt-Out: One Toggle, Big Trade-Off

1. Turn Off Gemini Apps Activity → myactivity.google.com/product/gemini → Toggle OFF or “Turn off and delete”

   • Stops training and human review (for new chats only)

   • BUT disables powerful features like:

     • Gmail, Docs, Drive integration (via Extensions)

2. 72-Hour Retention Even After Opting Out

   • Gemini still keeps your chats for 72 hours after opt-out for “service quality”

3. Human Reviewed Data Stays for 3 YEARS

   • Once a chat is flagged for review, it’s kept even if you delete it

   • Data is “disconnected from your account” but still stored by Google

Section IV: Hidden Trade-Offs and Dark Patterns

• OpenAI:

  • Easy opt-out costs you your chat history

  • Privacy Portal opt-out (best method) is buried, not in the app

  • “Memory” feature = stealth persistent tracking

• Google:

  • Only one way to stop training/review

  • But it cripples Gemini’s best features

  • Human-reviewed chats persist 3 years without deletion recourse

Section V: My Recommendations (Privacy-Oriented Setup)

OpenAI ChatGPT Plus

• Submit “Do Not Train” request via Privacy Portal

• Disable Memory completely or manage it weekly

• Use Temporary Chat for ultra-sensitive convos

• Be aware: nothing stops OpenAI from human review if abuse is suspected

Google Gemini Advanced

• Go to myactivity.google.com/product/gemini

• Turn OFF Gemini Apps Activity

• Turn OFF or limit Extensions (e.g., Workspace, Maps)

• Don’t re-enable “Web & App Activity” or “Location History” unless needed

Section VI: Final Thoughts – It's On You to Opt Out

Neither OpenAI nor Google guarantees total privacy, even when you're paying. The burden is on you to:

• Navigate fragmented settings

• Weigh privacy vs. features

• Stay up-to-date as policies shift

Both platforms encourage default data sharing through convenience, ambiguous UI, and “all-or-nothing” feature locks. If you care about your data—don’t trust defaults.
