People tell AI assistants things they would never put in a search box: health worries, salary negotiations, unlaunched product plans, code that is definitely not open source. Which makes the privacy question worth answering properly rather than with vibes.
The honest answer: your conversations are as private as your provider's policies, your settings, and your own sharing habits make them. Here is how to think about each layer.
Layer 1: what providers keep
Every major assistant stores your conversation history on its servers so it can show it to you later — that is the product working as designed. Providers also typically reserve the ability to review conversations for safety and abuse prevention, and may use conversations to improve their models depending on your plan and settings.
The details differ by provider and change over time, which is exactly why the settings layer matters more than any snapshot of policy.
Layer 2: settings worth checking today
- ChatGPT: look in Settings → Data controls for the model-improvement toggle, and use temporary chats for conversations that should leave no history.
- Gemini: your conversations are tied to your Google account's Gemini activity controls — review what is stored, for how long, and whether human review of samples is possible.
- Claude: check your privacy settings for the current training and retention choices on your account.
Layer 3: what you do with conversations
The biggest privacy events are usually self-inflicted: a share link forwarded beyond its audience, a screenshot with more in frame than intended, a conversation pasted into a tool that keeps a copy.
Online “chat to PDF” converters are the quiet offender in that last category — pasting a conversation into a random website to convert it means the site has your conversation. If the point of exporting is to keep control of your content, uploading it to a converter defeats the purpose.
Exporting without adding a new copy
This is the design constraint behind ChatKeepr: exports are generated inside the browser extension on your device and handed straight to Chrome's downloads system. No ChatKeepr account, no analytics, no developer server — the conversation's trust boundary does not grow just because you saved a file.
Keep the conversations that matter.
ChatKeepr exports ChatGPT, Gemini and Claude chats to polished PDF, Word or Markdown files — generated locally, never uploaded.
Frequently asked questions
Can AI companies read my conversations?+
Providers generally can access stored conversations under their policies — for safety review, for example — and may use them for model improvement depending on your settings. Treat the details as per-provider and check your data controls.
Is a temporary or incognito chat completely private?+
It keeps the conversation out of your visible history, which is different from it never existing on provider systems. It is a good tool for reducing your footprint, not an invisibility cloak.
Does exporting a conversation locally change what the provider stores?+
No. A local export creates your own copy; the original conversation remains in your account under the provider's normal retention rules until you delete it.
