Your vendors change what they promise by editing a web page. There is usually no email and no changelog, just a different sentence where the old one used to be. Your own customer contracts often turn their change into your deadline, and their data processing agreement may give you a fixed number of days to object, counted from when they publish.
Xither re-reads the pages each vendor publishes (sub-processor lists, data processing agreements, privacy and trust pages, and model retirement schedules) every day, keeps a dated copy of every reading, and tells you the morning one differs. Each alert shows the lines that moved, the vendor's own clause quoted word for word, and the date your window closes.
Xither reports what a page says, never what it means: every finding is a verbatim quote with its source address and the date it was read. Where a vendor publishes nothing, or blocks automated readers, Xither says so rather than leaving a gap.
