Is Perplexity AI safe?
Perplexity is generally safe to use for everyday research: it encrypts traffic and lets you delete history and opt out of model training. But by default your searches can be used to train its AI, and answers can still contain errors, so avoid entering sensitive personal, medical, or financial details and always verify important facts via the citations.
Why — the first-principles explanation
"Safe" has three different meanings here, and they matter separately. The first is data safety: what happens to what you type. Perplexity uses standard encryption and, on free, Pro, and Max plans, turns on AI Data Retention by default, meaning your queries can feed model training unless you switch it off. Enterprise data is contractually never used for training. So safety here is a setting you control, not an automatic guarantee.
The second meaning is accuracy safety: can you trust the answers? Because Perplexity retrieves live sources and cites them, it is easier to fact-check than a plain chatbot, but it can still misread a source or cite a weak one. That is why the citations exist, to let you verify rather than blindly trust, especially for health, legal, or money questions.
The third is account and privacy safety: who else sees your data. Perplexity's own agreements bar third-party model providers like OpenAI and Anthropic from training on your queries. However, a lawsuit filed in April 2026 alleged the app shares data with trackers, an unproven claim the company disputes. The prudent takeaway: use it freely for research, turn off data retention if you care about privacy, and never paste passwords, ID numbers, or confidential records.
An example that makes it click
Think of Perplexity like a helpful stranger at a library reference desk. They're knowledgeable and they point you to the exact books, so their answers are checkable. That makes them safer than a stranger who just tells you things from memory.
But you still wouldn't hand that stranger your bank PIN or your medical file. You'd take their reading suggestions, double-check the important pages yourself, and keep your private papers in your bag. Using Perplexity is the same: great for finding and verifying information, not a vault for your secrets.
How to do it
- Open Settings, find the AI Data Retention toggle, and turn it off if you don't want your searches used for training.
- Delete individual threads or clear your history from your account to remove stored queries.
- Never type passwords, ID numbers, full financial details, or confidential documents into any AI chat.
- Click the numbered citations to verify important answers before acting on them.
- For sensitive work data, use an Enterprise plan, which is contractually excluded from AI training.
Key facts
- Perplexity encrypts traffic and lets users delete history and opt out of model training.
- AI Data Retention is ON by default for free, Pro, and Max users; opting out applies to future data only.
- Enterprise data is never used for AI model training, per Perplexity's policy.
- Third-party model providers (e.g., OpenAI, Anthropic) are contractually barred from training on Perplexity data.
- An April 2026 lawsuit alleged undisclosed data tracking; the allegation is unproven and disputed by Perplexity.

Is Perplexity AI safe? For everyday research, yes, with a few smart habits. Let's break 'safe' into three parts. First, your data. Perplexity encrypts your traffic, but here's the key thing: by default, your searches can be used to train its AI. You can turn that off in settings under AI Data Retention. Second, accuracy. Because Perplexity shows its sources with clickable citations, it's easier to fact-check than a regular chatbot, but it can still get things wrong, so verify anything important. Third, privacy. Perplexity's contracts stop outside AI companies from training on your queries, though a 2026 lawsuit raised tracking concerns the company disputes. Bottom line: use it freely to research and learn, switch off data retention if privacy matters to you, always check the citations for big decisions, and never, ever paste passwords, ID numbers, or confidential files into it. Follow those, and it's a safe, powerful tool.
What authoritative sources say
People also ask
Does Perplexity keep my search history?
Yes, unless you delete it. You can clear individual threads or your whole history, and turn off data retention to limit training use.
Is it safe to ask Perplexity medical or financial questions?
It's fine for general research, but verify answers via the citations and never enter personal medical records, account numbers, or passwords.
Can Perplexity's answers be wrong?
Yes. Even with citations it can misread or cite weak sources, so treat it as a starting point and confirm important facts yourself.
