Worth knowing, in plain words
Terms in a privacy policy can be hard to read. These are the points that matter most for Perplexity, with a generic example of each. The examples are illustrations, not real cases.
No switch to flip
Where a policy describes no opt-out, there is no setting that stops your chats being used for the stated purposes. Your choices are whether to use the service and what to type into it.
Example, illustrative onlyYou look for a training switch in settings and find only a delete-history option. Deleting history is not the same as opting out of training.
What this page says: The privacy notice states no training opt-out setting and no training rule for user content.
“Not stated” is not “No”
When the pages we read are silent on a point, we say “Not stated”. That means we found no statement, not that the practice does not exist.
Example, illustrative onlyA page says nothing about human review. You cannot conclude that nobody reads chats; you can only conclude the page does not say.
What this page says: Human review is not stated on the notice we read.
