The privacy policy and terms of use are available online (links below). You can use html-xml-utils and pandoc (add to makedepends) to extract and convert the text.

Here's some code you may find helpful.

makedepends+=(
  'html-xml-utils'
  'pandoc'
)

_privacy_policy="qalvpn_privacy_policy"
_privacy_policy_url="https://qalvpn.com/privacy-policy"
_terms_of_use="qalvpn_terms_of_use"
_terms_of_use_url="https://qalvpn.com/terms-of-use"
#_acceptable_use_policy="qalvpn_acceptable_use_policy"
#_acceptable_use_policy_url=""
_disclaimer="qalvpn_disclaimer"
_disclaimer_url="https://qalvpn.com/disclaimer"

prepare() {
  local _content

  # terms of use 
  _content=$(curl -sSf "${_terms_of_use_url:?}")

  _content=$(
    hxnormalize -x <<< "${_content:?}" \
      | hxselect '.sqs-html-content' \
      | hxnormalize \
      2> /dev/null
  )

  pandoc --quiet -f html -t plain -o "${_terms_of_use:?}.txt" <<< "${_content:?}"

  # disclaimer

Hey @xiota, I couldn't find the license from upstream. It is a closed source application.
