Data retention and zero data retention (Gladia docs)

Gladia, n.d.

Read on October 22, 2026

What it is: Gladia's documentation of how long it keeps audio input, transcripts and metadata. It gives a default retention window by plan: 1 year on the Free plan and 3 weeks for audio on paid plans.
How much weight it carries: The maker's own documentation, the most specific source on retention. Custom and zero-retention options apply only to Enterprise customers, so the figures here are the default ones.
