Fireworks AI commits to no training on user data without opt-in and offers a zero-retention option for open models, but its terms take a perpetual sublicensable licence over user content and it names no security controls or breach notice.

What Fireworks AI's privacy policy and terms of service say about your data

Strongest disclosure

An explicit no-train commitment plus a named Zero Data Retention posture: "We do not log or store prompt or generation data for any open models without explicit user opt-in", scoped to open models and backed by a 30-day deletion timeline after account closure.

Adverse clause

The Terms take "a fully paid, royalty-free, transferable, perpetual, irrevocable, non-exclusive, and worldwide license, with the right to grant and authorize sublicenses" over User Content and Output, which overrides the separate "WE CLAIM NO OWNERSHIP RIGHTS OVER USER CONTENT" statement.

Rights are conditional

Every data-subject right is framed as "You may have a right" rather than an unqualified grant, covering access, portability plus correction. Only deletion has a concrete backstop, via the settings page and a 30-day window.

Security gap

No named security control, certification or breach-notification timeframe appears anywhere in the text; the security section offers only "reasonable efforts to protect your information" and a disclaimer that no measures are impenetrable.

What the policy is silent or vague on

Not stated: whether training use differs by plan
Not stated: your ownership of generated outputs
Not stated: a sub-processor list or data processing agreement
Not stated: its security safeguards
