How to Remain Safe Online When Using AI Chats Application

Popular AI chat platforms such as ChatGPT, Google Gemini, Claude, Microsoft Copilot, and Meta AI offer remarkable convenience and productivity benefits.

However, as these applications become more integrated into our personal and professional lives, they also introduce serious cybersecurity and data privacy concerns.

What happens to the information you share with an AI chatbot? Who can access your conversations? Can your private discussions become publicly available? And how can you protect yourself from hackers, data leaks, identity theft, and other online threats?

These questions have become increasingly important as people share sensitive personal information, confidential business documents, financial details, and even private conversations with AI systems.

The reality is simple: AI chat applications can be useful, but they should never be treated as completely private or risk-free environments.

This comprehensive guide explains the major cybersecurity and privacy risks associated with AI chat applications and provides practical steps to help individuals, professionals, and businesses use them safely.

1. Understand How AI Chat Applications Handle Your Data

Before using any AI chatbot, it is important to understand what happens when you enter a question, upload a document, or share personal information.

Unlike traditional offline software, many AI chat applications process your requests through remote servers operated by technology companies.

When you interact with an AI chatbot, the platform may process several types of information, including:

• Conversation content: Questions, instructions, responses, and messages exchanged with the chatbot.

• Personal information: Names, email addresses, phone numbers, or other details you voluntarily disclose.

• Uploaded documents: PDFs, spreadsheets, photographs, business reports, and other files.

• Technical information: IP addresses, device information, browser details, and usage activity.

• Account information: Login credentials, subscription information, and account preferences.

Depending on the service, this information may be retained for varying periods, reviewed for safety or abuse prevention, or used to improve AI systems.

Some platforms offer settings that allow users to limit whether their conversations are used for model training. Others provide temporary conversation modes or enterprise-level privacy protections.

Importantly, not every AI platform follows the same data collection, retention, or privacy practices.

How to protect yourself

Before using an AI chat application, review its privacy policy and data controls. Pay particular attention to whether conversations are stored, whether they can be used for training, who can access them, how long they are retained, and whether you can delete or export your information.

Avoid assuming that deleting a conversation from your visible chat history necessarily removes every copy immediately. Backup retention, legal obligations, and security policies may affect deletion timelines.

2. Never Share Sensitive Personal Information With AI Chatbots

One of the biggest mistakes people make when using AI chat applications is sharing more personal information than necessary.

Because AI chatbots respond conversationally, users may feel comfortable discussing information they would never publish on a website or social media platform.

For example, someone seeking financial advice might upload an entire bank statement, while another person might paste their passport details into a chatbot when requesting travel assistance.

Although these actions may seem harmless, they can unnecessarily expose sensitive information.

Information you should avoid sharing

Even when an AI service has strong security controls, sharing unnecessary sensitive information increases the potential impact of account compromise, accidental disclosure, or a security incident.

A safer approach

Instead of sharing real information, use fictional examples, placeholders, or properly anonymized data.

For instance, rather than entering your actual bank account details, you can ask:

Explain how to identify suspicious transactions on a sample bank statement.

Similarly, instead of uploading a customer database containing names, phone numbers, and addresses, remove identifying information and provide only the fields required for your analysis.

Remember that simply replacing someone’s name with “Customer A” may not make the information anonymous if other details can still identify the individual.

The golden rule: If an AI chatbot does not need a particular piece of information to answer your question, do not share it.

3. Be Extremely Careful When Sharing AI Chat Conversations

Sharing AI conversations with colleagues, friends, or online communities can be convenient. However, it also creates privacy risks that many users underestimate.

Some AI chat applications allow users to generate shareable links to their conversations.

Depending on the platform and sharing settings, anyone who obtains the link may be able to view the shared content.

This means a conversation containing confidential business strategies, financial information, personal problems, or private documents could become accessible to unintended recipients.

Sharing links may also be forwarded, saved, copied, or exposed through other websites and communication channels.

How to share AI conversations safely

1. Review the entire conversation before generating a sharing link.

2. Remove sensitive personal, financial, or business information.

3. Check whether the link is public, restricted, or accessible only to specific people.

4. Use access restrictions and expiration dates where the platform supports them.

5. Avoid publishing AI conversation links on social media or public forums.

6. Revoke previously shared links when they are no longer needed.

7. Where possible, copy only the relevant non-sensitive portion instead of sharing the entire conversation.

You should also check whether shared conversations contain uploaded documents, generated files, or earlier messages you did not intend to disclose.

Important: Disabling a shared link may prevent future access through that link, but it cannot guarantee that previously viewed information has not been copied, downloaded, or saved elsewhere.

4. Disable AI Model Training When Privacy Is a Priority

Many AI platforms improve their systems using information collected through user interactions. Depending on the provider and account settings, this may include conversations, uploaded files, and feedback.

Although model training can improve AI performance, users should understand whether their content is eligible for such use.

Disabling model training can reduce one category of data exposure, but it does not necessarily prevent the provider from storing or processing conversations for other purposes.

How to manage training settings on popular AI platforms

Privacy controls change over time, and some features vary by country, subscription, or organization. Always consult the provider’s official documentation before relying on a particular setting.

5. Enable Two-Factor Authentication to Protect Your AI Accounts

Cybercriminals do not always need to compromise an AI company’s servers to obtain private conversations. Sometimes, gaining access to an individual’s account is enough.

If an attacker steals your password and successfully logs into your AI account, they may be able to view saved conversations, access uploaded files, or misuse connected services.

This makes account security extremely important.

Two-factor authentication (2FA), also called multi-factor authentication (MFA), adds another layer of protection beyond a password.

Depending on the platform, this may involve a passkey, authenticator application, security key, or verification code.

Recommended account security practices

• Use a strong, unique password for every AI service.

• Enable MFA, preferably using phishing-resistant passkeys or security keys when supported.

• Never share verification codes with anyone.

• Avoid reusing passwords from email or social media accounts.

• Review active login sessions and sign out of unfamiliar devices.

• Use a reputable password manager.

• Secure the email account associated with your AI subscriptions.

Remember that MFA significantly reduces account takeover risk, but it does not eliminate threats such as stolen session cookies or sophisticated phishing attacks.

6. Beware of Fake AI Chat Applications and Phishing Websites

As AI chatbots become increasingly popular, cybercriminals are taking advantage of their popularity to create fake applications, fraudulent websites, and misleading advertisements.

Some malicious websites imitate legitimate AI platforms to trick visitors into entering their login credentials, installing malware, or paying for fake subscriptions.

Others advertise unauthorized AI tools that promise premium features for free.

These services may attempt to collect personal information or compromise devices.

Warning signs of a suspicious AI application

Be cautious if an AI service asks you to download an unfamiliar executable file, disable antivirus protection, enter your banking password, or grant extensive device permissions without a clear reason.

Other warning signs include unusually aggressive advertising, misleading domain names, poor contact information, and subscription offers that appear too good to be true.

How to avoid fake AI platforms

Download mobile applications through official app stores, verify the developer’s identity, and access web-based services through their legitimate domains.

Do not assume a website is trustworthy simply because it displays a padlock icon or uses HTTPS. Encryption protects the connection, but it does not establish that the website operator is legitimate.

7. Avoid Uploading Confidential Business Documents Without Authorization

AI chat applications can help businesses summarize contracts, analyze financial statements, review customer feedback, and prepare strategic reports.

However, uploading confidential documents to an AI service without appropriate safeguards can create significant security and compliance risks.

Imagine an employee uploading an internal document containing company financial projections, customer records, or proprietary source code to a personal AI account.

Even if the employee intends only to summarize the document, the organization may lose control over how that information is processed, retained, or shared.

Potential consequences include breaches of confidentiality agreements, exposure of trade secrets, contractual disputes, and violations of data protection laws.

What businesses should do

Organizations should establish an AI acceptable-use policy specifying which applications employees may use and what information they are permitted to submit.

Businesses handling sensitive information should evaluate enterprise AI offerings that provide contractual protections, administrative controls, appropriate retention settings, and security assurances.

For example, OpenAI states that content submitted through its Business, Enterprise, Edu, and API offerings is not used for model training by default. However, organizations must still assess their own security configurations and data processing requirements.

8. Understand the Dangers of AI Chat History and Memory Features

Many AI platforms maintain conversation histories so users can return to previous discussions.

Some also provide memory or personalization features that allow the assistant to use information from previous interactions to deliver more relevant responses.

While these capabilities can be useful, they also introduce additional privacy considerations.

For example, an AI assistant might retain useful information about your work, interests, or preferences. If the account is compromised or another person gains access to it, that information could become exposed.

How to reduce the risks

Periodically review your conversation history and delete chats you no longer need.

Check memory and personalization settings separately from model-training controls. Deleting a conversation does not necessarily delete information retained by a separate memory feature.

When discussing sensitive matters, consider temporary conversation modes.

ChatGPT, for example, offers Temporary Chat, which stays out of history and is not used to improve OpenAI models while it remains temporary. OpenAI may nevertheless retain a copy for up to 30 days for safety purposes.

9. Be Careful When Connecting AI Chatbots to Third-Party Applications

Modern AI assistants increasingly integrate with email services, cloud storage, calendars, project management platforms, and other digital tools.

These integrations allow AI systems to perform tasks using information stored in external accounts.

For example, a connected AI assistant might summarize emails, analyze files stored in cloud storage, or help organize a work calendar.

However, granting an AI application access to another service expands the potential consequences of account compromise, misconfiguration, or malicious instructions.

The principle of least privilege

Cybersecurity professionals recommend granting applications only the permissions necessary to complete their intended tasks.

If an AI assistant needs to read a particular document, it should not automatically receive unrestricted access to an entire cloud storage account.

Similarly, an assistant that only needs to summarize emails should not receive permission to send or delete messages unless those capabilities are genuinely required.

Review connected applications regularly and revoke permissions that are no longer necessary.

Where supported, require explicit confirmation before an AI assistant sends messages, deletes files, makes purchases, or performs other sensitive actions.

10. Protect Yourself Against Prompt Injection Attacks

One of the emerging cybersecurity threats associated with AI assistants is known as prompt injection.

A prompt injection attack occurs when malicious instructions are embedded in content that an AI system reads or processes.

For example, an attacker might insert hidden instructions into a website, email, or document that an AI assistant is asked to summarize.

Those instructions could attempt to manipulate the assistant into ignoring the user’s original request, disclosing information, or performing unauthorized actions.

OpenAI identifies prompt injection as an evolving security challenge and recommends limiting AI agents’ access to sensitive information and reviewing actions before confirming them.

How to reduce prompt injection risks

Avoid giving AI agents unrestricted access to important accounts or systems.

Treat instructions found in external documents, websites, and emails as untrusted. Review any proposed actions involving financial transactions, file modifications, or sensitive communications.

Businesses deploying AI agents should also implement permission boundaries, monitoring, and human approval requirements for high-impact actions.

11. Do Not Blindly Trust AI-Generated Information

Cybersecurity risks involving AI are not limited to data theft and privacy breaches.

AI chatbots can sometimes produce incorrect information, fabricate references, misinterpret documents, or present uncertain claims with excessive confidence.

This phenomenon is commonly described as AI hallucination.

Blindly following inaccurate AI-generated information can have serious consequences, particularly in healthcare, finance, legal matters, and cybersecurity.

For example, an AI assistant might recommend an outdated security configuration, invent a legal requirement, or incorrectly interpret a financial document.

How to verify AI-generated responses

Check important claims against authoritative sources.

For cybersecurity advice, consult reputable security organizations, official software documentation, and recognized security standards.

For medical, legal, or financial decisions, seek qualified professional guidance when necessary.

AI should support informed decision-making rather than replace independent verification.

12. Keep Your Devices, Browsers, and AI Applications Updated

Using a legitimate AI platform does not automatically protect you if the device accessing it is compromised.

Outdated operating systems, browsers, extensions, and mobile applications may contain vulnerabilities that attackers can exploit.

A compromised device could expose AI conversations through stolen login sessions, malicious browser extensions, screen capture, or other forms of unauthorized access.

Essential device security measures

Enable automatic security updates for your operating system and applications.

Install browser extensions only from trusted developers and remove those you no longer need.

Use reputable security software where appropriate, enable device encryption, and secure your devices with strong authentication.

Avoid using shared or public computers to access AI accounts containing confidential conversations.

When using public Wi-Fi, confirm that you are connected to the intended network and use encrypted websites. A trustworthy VPN can provide additional protection in some circumstances, but it does not prevent phishing, malicious applications, or unsafe information sharing.

13. Understand Your Data Privacy Rights

Users should understand that their personal information may be protected by privacy and data protection laws.

Depending on their location and the circumstances of processing, these laws may give individuals rights to access personal information, request corrections, seek deletion, or object to certain forms of data processing.

Examples include:

• The European Union’s General Data Protection Regulation (GDPR).

• Nigeria’s Nigeria Data Protection Act (NDPA) 2023.

• Applicable state privacy laws in the United States.

• Other national and regional data protection legislation.

These laws do not all provide identical protections, and their applicability depends on factors such as jurisdiction, the organization’s activities, and the nature of the information involved.

Before sharing sensitive data with an AI provider, review its privacy policy, applicable data processing agreements, and available privacy request procedures.

If you believe your personal information has been mishandled, contact the provider and consider submitting a complaint to the relevant data protection authority.

For Nigerian users, the Nigeria Data Protection Commission (NDPC) is an important official resource.

14. What to Do If You Accidentally Share Sensitive Information With an AI Chatbot

Mistakes happen. You might accidentally paste a password, upload a confidential document, or share a conversation containing private information.

When this occurs, the most important thing is to respond quickly and appropriately.

Immediate actions to take

If the exposure involves a company or customer information, preserve appropriate incident records and seek guidance from your security or legal team before destroying evidence.

Are paid AI chat applications more secure than free versions?

Not automatically. Some paid business and enterprise services offer additional security, privacy, and administrative controls, but subscription price alone does not guarantee stronger protection.

Should I stop using AI chatbots because of privacy concerns?

Not necessarily. AI applications can provide significant benefits when used responsibly. The objective should be to understand the risks, limit unnecessary disclosure, and choose services with appropriate privacy protections.

Conclusion: Stay Smart, Stay Private, and Stay Safe When Using AI Chats

AI chat applications are becoming a permanent part of modern digital life. They help individuals improve productivity, support businesses, accelerate research, and simplify complex tasks.

However, the convenience of artificial intelligence should never come at the expense of personal privacy or cybersecurity.

Every question you ask, document you upload, account you connect, or conversation you share can introduce some degree of information security risk.

Protecting yourself begins with understanding how AI services process information and taking responsibility for the data you disclose.

Use strong account authentication, review privacy settings, minimize sensitive information, verify AI-generated responses, and exercise caution when sharing conversations or connecting external services.

Businesses should go further by implementing clear AI usage policies, employee training, access controls, and appropriate data protection agreements.

Ultimately, the safest approach is not to avoid artificial intelligence entirely, but to use it with the same security awareness you would apply to online banking, cloud storage, email, and other important digital services.

AI can help you work smarter, but protecting your privacy requires you to use it smarter, too.
