Perplexity: data residency & retention
Headquarters
🇺🇸 United States (US)
Where inference runs
Not disclosed
Perplexity's API documentation does not disclose the regions where Sonar API inference runs.
Region pinning
Not disclosed
No data-residency or region-pinning options are published for the Sonar API.
Prompt retention
Not retained
Perplexity states a strict zero-data-retention policy for its API: prompts and responses are not stored; only operational/billing metadata is retained.
Trains on API data
No
Perplexity does not use API customer data to train its models (unlike consumer plans, where AI data retention is on by default unless the user opts out).
Zero data retention
Available
Zero data retention is the default for all API traffic rather than an opt-in tier — no approval or enterprise contract required.
