How to Keep Your AI Conversations Completely Private

What cloud AI platforms do with your conversations

Understanding what happens to your data is the first step.

ChatGPT (OpenAI)

By default, OpenAI stores your conversations and may use them to improve their models. You can opt out of training data use in Settings → Data Controls → Improve the model for everyone — but your conversations are still stored on OpenAI's servers. OpenAI's privacy policy gives them broad rights over how stored data is handled.

Claude (Anthropic)

Anthropic stores conversations by default. Like OpenAI, they offer controls to limit how your data is used for training, but conversations still pass through and are stored on their infrastructure.

DeepSeek

DeepSeek is operated from China and stores conversation data on servers in China. This has raised significant privacy concerns, particularly for users in regulated industries or those handling sensitive information.

The common thread

In every case: your conversations leave your device, travel over the internet, and are stored on a third-party server. You have limited visibility into exactly how that data is used, retained, or protected — and limited recourse if something changes.

Turn off conversation history and training

Every major AI platform offers some controls over how your data is used. These won't give you complete privacy, but they're a meaningful first step.

ChatGPT:

1. Go to Settings → Data Controls
2. Turn off “Improve the model for everyone” — this opts you out of your conversations being used for training
3. Turn off “Save new chats” if you don't want conversations stored at all (note: this also means you lose chat history between sessions)

Claude:

1. Go to Settings → Privacy
2. Review the available data controls and opt out of training data usage where possible

DeepSeek:

1. Go to Settings → Privacy
2. Disable conversation history if the option is available

Export and archive your conversations locally

Regardless of which platform you use, exporting your conversation history and storing it locally is one of the most practical privacy steps you can take. It means:

• You have a copy of your data that you control
• If a platform changes its policies, closes your account, or goes offline, your history is safe
• You're not dependent on a cloud service to access your own conversations

How to export:

• ChatGPT: Settings → Data Controls → Export Data — you'll receive a ZIP file by email. Full guide →
• Claude: Account settings → Export conversations. Full guide →
• DeepSeek: Account settings → Export data. Full guide →

Once you have your export, import it into AI Chat Importer to create a local, searchable archive that never touches a server. All processing happens on your device.

Use a local AI model for sensitive conversations

For conversations you want to keep completely off any external server, the answer is a local AI model — one that runs entirely on your own machine.

With a local model:

• Your prompts never leave your device
• No company can store, analyse, or train on your conversations
• You get a capable AI assistant with complete data sovereignty

The easiest way to get started: Ollama

Ollama is a free tool that lets you run AI models locally on Windows, Mac, or Linux. It takes about 10 minutes to set up and works on most modern hardware — you don't need a powerful GPU.

See our Ollama setup guide for full installation instructions and model recommendations based on your hardware.

For users on lower-end machines, our low-end hardware guide covers which models work best with 8GB RAM or no GPU.

Back up your local archive regularly

A local archive is only as good as your backup habits. If your device fails and you have no backup, you lose everything.

Simple backup options for your AI Chat Importer archive:

• External hard drive or USB drive: Copy your archive folder periodically. On Windows, your conversations are stored in %APPDATA%\ai-chat-importer\conversations\.
• Local NAS or home server: A network-attached storage device gives you automatic local backups without any cloud involvement.
• Encrypted cloud backup: If you use cloud storage, encrypt your archive first using a tool like VeraCrypt or 7-Zip with AES encryption before uploading. This means even if the cloud provider is compromised, your conversations can't be read.

The AI Chat Importer desktop app's Export Data feature (Settings → Export Data) creates a single JSON backup file of your entire archive — use this as the source file for any backup method.

What about using a VPN?

A VPN encrypts your internet traffic and hides your IP address — but it doesn't make your AI conversations private from the AI platform itself. When you use ChatGPT through a VPN, OpenAI still receives your messages — you've just changed who can see your IP address in transit.

A VPN is useful for:

• Accessing AI platforms from regions where they're blocked
• Preventing your ISP from seeing which AI services you use

A VPN does not:

• Prevent the AI platform from storing your conversations
• Change how your data is used by the platform
• Give you meaningful privacy over the content of your prompts

For genuine conversation privacy, a local model is the only reliable solution.

Quick privacy checklist

Run through this before your next AI session:

• Opted out of training data usage on ChatGPT, Claude, and DeepSeek
• Exported your conversation history from each platform
• Imported exports into a local archive with AI Chat Importer
• Set up Ollama for sensitive conversations that should never leave your device
• Created a local backup of your archive
