ChatGPT Features – Memory retention, custom instructions and privacy
ChatGPT 5’s Memory System
ChatGPT 5 is designed to handle conversations efficiently while keeping track of important details. It can process up to 32,768 tokens (roughly 10,000 words) in active discussions .
Session Memory vs Permanent Storage
ChatGPT 5 uses two distinct memory types: session memory and permanent storage. During a chat, it maintains a context of about 8,000 tokens (around 6,000-6,500 words) . As the conversation progresses, older parts are automatically removed to stay within this limit.
| Memory Type | Capacity | Duration | User Control |
|---|---|---|---|
| Session Memory | 8,000 tokens | Single chat | Resets after chat ends |
| Permanent Storage | No fixed limit | Across sessions | Manual deletion required |
| Temporary Chat | 8,000 tokens | Single chat | No data retained |
Permanent storage, when enabled, keeps important details across multiple sessions with no fixed size limit. It updates with each interaction . These differences in memory handling contribute to the improved functionality of ChatGPT 5.
Changes from Previous Versions
ChatGPT 5 introduces several upgrades to its memory features :
- Memory Notifications: The model now informs you when it updates its memory and allows you to review stored details .
- User Commands: You can tell the AI to remember or forget specific details directly .
- Wider Availability: Memory features are accessible to all users, whether on Free, Plus, Team, or Enterprise plans .
It’s worth noting that the system doesn’t save entire documents or lengthy texts automatically . Instead, it focuses on remembering key details like preferences, personal information, and communication styles to enhance future interactions.
Privacy of Your ChatGPT 5 Chats
What Data Gets Stored
ChatGPT 5 collects and retains various types of data during your interactions:
| Data Type | Examples | Retention Period |
|---|---|---|
| User-Provided | Prompts, questions, responses, uploaded files | Stored until manually deleted (if chat history is enabled) |
| System-Generated | Timestamps, usage stats, IP address, location | Retained for a limited time |
| Account Details | Name, email, phone number, payment info | Kept as long as your account is active |
OpenAI uses this data primarily to refine its AI models . While the company states it anonymizes data by removing identifiable details , conversations may still carry some exposure. This setup highlights the importance of understanding how your chat data is managed.
Managing Your Chat Data
Understanding what’s stored helps you take control of your data.
-
For web users:
- Use the ellipsis next to a chat to delete it .
- Navigate to Settings > General and select "Clear all chats" .
-
For mobile app users:
- Tap the two-line menu icon, then the ellipsis beside your name.
- Go to Data Controls to manage or delete chats .
You can also enable temporary chats, which delete automatically after 30 days and are not used for model training . These tools work alongside ChatGPT 5’s memory management options.
Known Privacy Risks
Despite these controls, there are still risks. For example, a bug in an open-source library exposed some users’ chat titles and histories, including payment details for about 1.2% of ChatGPT Plus subscribers during a nine-hour period .
Other privacy concerns include:
- Logging of IP addresses, network details, and device information .
- Retention of all prompts and queries .
To safeguard your privacy:
- Use a VPN to hide your IP address.
- Disable data training in the settings menu.
- Request data removal through OpenAI’s privacy portal .
- Avoid sharing sensitive personal details in chats .

For extra safety, all deleted conversations are permanently erased from OpenAI’s systems within 30 days unless legal requirements dictate otherwise .
Ways to Keep Your Chats Private
Safety Tips for Users
Keeping your conversations private starts with good habits. Avoid sharing sensitive details like passwords, financial info, or personal identifiable information (PII) in your chats .
Here are a few ways to enhance your security:
- Disable model training: Go to Settings > Data Controls and opt out of having your chats used for model training .
- Use temporary chats: These automatically delete after 30 days and aren’t included in training data .
- Enable two-factor authentication: Add an extra layer of protection to your ChatGPT account .
Be cautious when using third-party GPTs or plugins, as they may follow different privacy rules . If you’re concerned about your online footprint, consider using a VPN to hide your IP address .
Taking charge of your privacy isn’t just about settings – it’s also about managing your chat history effectively.
How to Clear Chat History
Clearing your chat history is straightforward on both desktop and mobile:
- Open Settings (on desktop) or Data Controls (on mobile)
- Choose "Delete All Chats" or "Clear Chat History"
- Confirm the action
These steps, combined with memory management features, let you stay in control of your data.
Reading Privacy Policies
Another key step is reviewing privacy settings to ensure consistent data protection across your devices. Here’s a quick guide to what you should check:
