Are AI 'Temporary Chats' Truly Safe? Data Retention and Training Black Boxes Questioned

EriksonThorsen · reddit · 2026-08-04

A Reddit user raised privacy concerns regarding the "temporary chat" modes offered by major AI companies. Although OpenAI, Google, and Anthropic claim such data isn't saved or used for training, the author found policy loopholes: OpenAI retains data for 30 days for abuse monitoring, Google for 72 hours, and Anthropic's backups may persist for 30 days.

Given the immense value of real conversational data for model training (like RLHF), the author is skeptical that companies truly discard it. In contrast, API and enterprise tiers (e.g., Claude for Work) are deemed more trustworthy for not training on user data, backed by the threat of severe legal and commercial repercussions. The post sparked broad discussion on corporate trustworthiness and the vague boundaries of terms like "product improvement."
