Your AI Knows More Than You Think: A Privacy Comparison of Claude, ChatGPT, and Gemini
Your AI Knows More Than You Think: A Privacy Comparison of Claude, ChatGPT, and Gemini
Every day you paste contracts, salaries, medical questions, legal documents, and business strategies into AI. You dictate voice notes to it. You trust it more than most of your coworkers.
But what happens to everything you tell it?
We read the privacy policies so you don't have to. Here's what we found — and why it's exactly the reason we built Wysor.
Your $20/month subscription doesn't buy you privacy
Claude Pro. ChatGPT Plus. Gemini Advanced. You might assume paying $20/month gets you better data protection than the free tier.
It doesn't. Free or paid, every consumer plan has the same policies: your conversations are used for training, they can be reviewed by humans, and they're retained far longer than you think.
The only way to get real privacy from these providers is to negotiate an enterprise contract — different terms, different pricing, and a sales team standing between you and your data.
We built Wysor so you don't have to make that call.
How long your conversations sit on their servers
| Claude Pro | ChatGPT Plus/Pro | Gemini Advanced | Wysor | |
|---|---|---|---|---|
| Default retention | 30 days (or 5 years if training opted in) | Indefinite | 18 months | 30 days max (OpenAI). Others: zero. |
| After you "delete" | 30 days to actually remove | 30 days to actually remove | 72 hours minimum | Minimized via dedicated DPAs. |
Claude keeps your data for 30 days by default. But in October 2025, Anthropic quietly made training opt-in the default — meaning if you missed the prompt, your conversations may now be stored for up to 5 years.
ChatGPT keeps everything forever. Your conversations sit in OpenAI's systems until you manually delete them, then they take another 30 days to actually remove them.
Gemini retains for 18 months. Even if you turn off "Keep Activity," Google still holds your data for 72 hours. There is no true zero retention on any consumer Gemini plan.
Wysor's dedicated DPAs with every provider minimize retention to the absolute technical minimum — and for most providers, that's zero. Your conversations live in your workspace, not sitting on provider servers for months or years.
All three use your conversations to train their models
By default. All of them.
- Claude: Opt-in since October 2025 — but Anthropic defaulted it to "on" for users who didn't actively respond
- ChatGPT: On by default. Buried in Settings > Data Controls
- Gemini: On by default. Disable "Keep Activity" to opt out
That contract you pasted in? It's now training data. That salary negotiation? Training data. That medical question you were too embarrassed to ask your doctor? Training data.
The only way to stop this is an enterprise plan — and that's a $25k+ conversation with a sales team.
Wysor never trains on your data. Not on free. Not on paid. Not on any plan. It's contractual, not a toggle.
Someone at Google might be reading your chats right now
This one shocks people.
Google is at least honest about it. They explicitly warn Gemini users: "Don't enter confidential information that you wouldn't want a reviewer to see." Human-reviewed conversations are stored for up to 3 years, disconnected from your account — and deleting the conversation does not delete the reviewed copy.
OpenAI samples 1-2% of all conversations for human review, plus anything flagged by automated systems.
Anthropic routes flagged Claude conversations to their Trust & Safety team. Those flagged inputs and outputs can be retained for up to 2 years, with safety scores kept for up to 7 years.
With Wysor, no human at any AI provider ever sees your conversations. Our DPAs contractually prohibit human review, sampling, and flagging. Nobody is reading your chats.
"Delete" doesn't mean what you think it means
- Gemini: If your conversation was selected for human review before you deleted it, that copy persists for up to 3 years. You can't remove it. You might not even know it exists.
- Claude: Flagged conversations are retained for up to 2 years. Deleting changes nothing.
- ChatGPT: In 2025, a federal judge in NYT v. OpenAI ordered OpenAI to preserve all conversation data — including chats users had explicitly deleted — as potential evidence. Free, Plus, Pro, and Team users were all affected. Enterprise and API customers were exempt, this time.
With Wysor, delete means delete. When providers don't hold your data beyond the minimum processing window, there's nothing to flag, nothing to preserve for litigation, and nothing lingering on a server three years from now.
A federal judge just ruled your AI chats aren't privileged
In February 2026, United States v. Heppner established that conversations with Claude AI are not protected by attorney-client privilege and do not constitute work product.
The reasoning: Anthropic's policies allow disclosure to governmental authorities and permit use for model training. There is no reasonable expectation of confidentiality.
The precedent is clear: every AI conversation on a consumer plan is potentially discoverable in legal proceedings.
This is exactly why minimizing provider-side retention matters. A court can't compel a provider to hand over data that was never stored.
Your voice is going places you didn't agree to
AI voice features are popular. The data pipelines behind them are alarming.
Claude Voice
- Audio is sent to Anthropic's servers, then deleted within ~24 hours
- When Claude talks back, it uses ElevenLabs — a third party — for text-to-speech. Your conversation content is sent to their servers
- The speech-to-text provider is not publicly disclosed
- No public Zero Data Retention arrangement between Anthropic and ElevenLabs
ChatGPT Voice
- Audio and video clips are stored alongside your conversation for as long as the chat exists
- OpenAI is the only provider that retains your actual audio recordings by default
- Audio isn't used for training, but text transcripts may be if you haven't opted out
Gemini Voice
- Google's "Ephemeral Learning" sounds good — audio processed in RAM and deleted. But it only applies to wake-word training ("Hey Google"), not your actual requests
- Your voice requests are still sent to Google's servers. In 2019, contractors were caught listening to over 1,000 recordings, including accidental activations that captured bedroom conversations and medical info. Google settled for $68M
- A separate class action covering accidental activations from 2016-2022 is still pending in 2026
Apple Siri
- Server-processed requests: Apple stores transcripts for up to 2 years for all users
- On-device dictation stays local, but Apple still collects metadata — request category, device info, performance stats
- If you accidentally opt into "Improve Siri," Apple keeps your actual voice recordings for up to 2 years, reviewable by employees
- Apple claims a "random, rotating identifier" protects anonymity. But they collect your IP, location, contacts, and device info alongside every request — that's pseudonymization, not anonymization
- Apple settled a $95M lawsuit over inadvertent Siri activations
Wysor Voice
- Everything happens on your device. Your audio never leaves your phone
- No servers. No third parties. No cloud processing. Works offline
- We can't leak your voice data because we never receive it
Enterprise plans won't save you either
The big providers will tell you to upgrade. But even if you can stomach the cost, there's a problem they don't mention: if your data exists on their servers, a court can compel them to hand it over.
| Claude Enterprise | ChatGPT Enterprise | Gemini Workspace | Wysor | |
|---|---|---|---|---|
| What it costs to get ZDR | API only, by approval | $25k+ spend, special approval | Not default, requires config | Nothing. It's the default. |
| Data exposure window | Indefinite (flagged data retained) | Indefinite (unless ZDR negotiated) | Indefinite (unless configured) | 30 days max (OpenAI only). Others: zero. |
| Human review | Flagged conversations still reviewed | Flagged (none with ZDR) | None | None. Contractually guaranteed. |
You can spend $25k and negotiate for months to get protections that still leave your data on someone else's servers. Or you can use Wysor, where dedicated DPAs minimize provider retention to the technical minimum, no human reviews your conversations, and you never talk to a sales team to get privacy that should have been the default.
So what do you actually do about this?
Right now, your employees are pasting contracts into ChatGPT, discussing strategy with Claude, and uploading customer data to Gemini. Every one of those conversations is stored, reviewable, trainable, and discoverable in court.
You have two options.
Option A: Ban AI at work. Watch your competitors outpace you while your team uses it anyway on personal devices — now with zero oversight and zero protection.
Option B: Give them Wysor. Every major model — GPT-5, Claude, Gemini, Perplexity — in one workspace. Dedicated DPAs that minimize provider retention. No human review. No training. On-device voice transcription. Full GDPR compliance. One audit trail instead of data scattered across four providers.
The companies that figure this out first don't just avoid risk. They move faster than everyone still arguing about whether to block ChatGPT.
