Undress.app describes a web-based platform in its terms. It offers one-time token packs and fixed-duration access plans that do not auto-renew. Its terms describe undress, sex, video and face-swap modes for Pro access, subject to current availability.
Undress.app says it does not store user-generated images, while NudeFast stores results for 3 days. These are published policy statements, not independent technical audits. We have not compared output quality.

Honest trade-offs
Both services publish browser-based access, so an install-versus-browser framing would be misleading. The clearer difference is payment: NudeFast shows credit plans, while Undress.app’s terms describe one-time token packs and fixed-duration access plans without auto-renewal.
NudeFast says results are kept in your account for 3 days and then deleted. Undress.app says in its terms that it does not store user-generated images. Those statements have not been independently audited here.
