How to stop Signal training AI on your data
What the policy itself says, plan by plan. Where Signal publishes the steps, they're here in its own words, read from an archived copy of the page that gives them. Where it doesn't, this page says so instead of inventing a menu path.

There is nothing to opt out of. Signal's own policy says it can't reach the content, so training on it isn't something a setting controls.
"Signal cannot decrypt or otherwise access the content of your messages or calls."
Did a step here not work, or does Signal offer a control this page doesn't mention? Tell us and we'll correct it.
