How we read documents ?We review the vendor's own public documents, like their terms of service, privacy policy, data processing agreement, and trust pages. Some answers come from a vendor's help or website pages, which are not contract terms, so each source is labelled with the kind of document it is. Every answer below carries a short quote or excerpt, a link to the source, and the date we captured it.
