Subprocessors
Last updated October 30, 2026

AI and search data providers
This is the part that makes Signal work: to measure how answer engines describe a brand, Signal has to ask them. Prompts you configure are sent to these providers, either directly through their APIs or through a scraping provider that queries the consumer product on our behalf. The answers come back to us, are stored in your account, and are analyzed to see how they describe the brands you track.
What they receive is what you've configured in Signal — your prompts, which are market-research queries like "best project management software for agencies", and for some features your brands, competitors, tracked domains, and text from your website — rather than your name, email address, or billing details. Do not put personal data into a prompt.
Which of these is used depends on the platforms your plan tracks and how Signal is configured at the time.
