How to Opt Out of Perplexity AI Data Collection
Opt out of AI services use of your personal information for future training data.
Perplexity is an AI-powered search tool that collects search and interaction data by default. Logged-in users can opt out of having their search information used to improve Perplexity's AI models. You can also request a copy of your data or delete your account entirely. This 2026 guide walks through each option and the limits to expect.
Why this matters. AI training data isn't always a single switch — many platforms scatter the controls or rely on objection forms. Settings also drift: opt-outs can reset after policy changes or product updates. Priwall by mePrism monitors AI privacy settings across the services you use and alerts you when something changes.
Why opt out of Perplexity AI data collection?
Search queries reveal sensitive interests — health questions, financial research, legal concerns, work plans. When that data feeds into AI model improvement, it becomes part of a system that may shape how Perplexity responds for many other users. Logged-in users can prevent their search data from being used for AI improvement, and you have separate rights to request a copy of your data or delete your account. Enterprise accounts have stronger default protections.

How to opt out of Perplexity AI data collection
- Sign in to Perplexity. Open perplexity.ai and sign in to your account.
- Open Settings. Click your profile icon or navigate to Settings.
- Find AI information collection. Look for the AI information collection toggle or opt-out option in your settings.
- Turn it off. Switch the toggle off so your future search activity is not used to improve Perplexity's AI models. Save changes if prompted.
- Request a data copy (optional). Visit perplexity.typeform.com/datarequest and complete the form to request a copy of the data Perplexity holds about you.
- Delete your account (optional). Use the account deletion option in Settings, or email support@perplexity.ai, if you want to remove your account entirely.
Steps current as of 2026; if the platform has changed its flow, see their current privacy or settings page.
AI privacy controls change. Often.
Priwall by mePrism finds your AI opt-out controls across major platforms, helps you turn them off, and monitors for changes — so a single policy update doesn't silently re-expose your data.
What to expect after opting out
Once the AI information collection toggle is off, future logged-in search activity is excluded from Perplexity's AI model improvement. Past data already collected is not automatically removed — use the data request and account deletion options for that. The opt-out applies to logged-in sessions, not unregistered/guest use. If you use Perplexity through a workplace Enterprise account, data is not used for training by default and your administrator can disable history org-wide.
Frequently asked questions
Does this apply if I'm signed out?
No. The setting controls logged-in account activity. Use a private/incognito window if you want to avoid associating queries with your account.
Does opting out delete past data?
No. Use the data request form and account deletion to handle past data separately.
How long does Perplexity keep uploaded files?
In an enterprise context, uploaded files are automatically deleted after seven days, per Perplexity's enterprise privacy documentation.
How do I delete my account?
Use the account deletion option in Settings, or email support@perplexity.ai.
Are enterprise accounts treated differently?
Yes. Enterprise data is not used to train or fine-tune models, and admins can disable search history for everyone in the organization.
