Address book
Stores names, numbers and contact details. If a team needs to maintain one shared list, decide access rights, ownership and privacy rules first.
Apple Contacts and Google Contacts are personal address books, not a jointly managed customer database.
Contact sync
Keeps the same address book current across devices. Check the account or address-book provider's sync, including how it handles conflicts and deletions.
A one-time CSV or vCard export is an import, not ongoing sync. End-to-end encrypted sync over storage you run yourself — a local or shared folder, or a WebDAV server — is planned for v1. Google Drive as a destination is not decided yet. Managed sync on Endearist Cloud is planned for after v1, as part of the Pro Cloud subscription only.
Personal CRM
Adds relationship context: how you met, what you discussed and when to follow up. A private spreadsheet or note can be enough to begin.
Endearist is intended to add that layer later. The app has not launched; see the roadmap for its planned scope.
