katib is a personal assistant that Mohamed Ibrahim (MK Builds LLC) runs for himself and a few people he invites. It is not a company product and has no support team.
An invite is required. This site does not create an account. Pairing happens on a link Mohamed sends you, then a code you text from your own iPhone.
Use of Google data follows the privacy note, including Google's Limited Use requirements.
Text "freeze" to stop everything except answers, drafts and disconnecting. "Delete my account" needs Face ID. Your data is then deleted and your key is destroyed after 7 days.
The privacy note is the rest of how this works. When a control changes, that note changes in the same update.
