Concepts and glossary

Term (EN / NL)	Definition
Account / account	The sign-in identity (e-mail, Google or Apple). Owns one or more profiles. Deleting the account deletes everything.
Profile / profiel	A person’s set of details and settings. The account’s first profile is the main profile; extra managed profiles (for example a child) can be added and are administered by the same account. Everything below is per profile.
Detail / gegeven	One piece of contact information: a name, a phone number, an e-mail address, an address, a special date or a photo. A profile can have several of each.
Type / soort	The label on a detail: Personal, Work, Mobile, Home, Birthday, Anniversary, or a custom type the user defines (“Gaming”, “Holiday home”). Types help the receiver file the detail correctly.
Sharing circle (circle) / deelkring (kring)	A named, coloured group of connections that receive the same set of details. Every profile starts with Family, Friends and Work and can add more. A connection is in exactly one circle.
Circle assignment / gedeeld met	The set of circles that may see a detail. Chosen per detail (and for dates separately for day-month and year; for addresses optionally per field).
Searchable / vindbaar	A flag on a name, phone or e-mail that allows people who already know that exact value to find the profile.
Connection (contact) / connectie (contact)	A mutual link between two profiles. Each side places the other in one of its own circles. A connection has a status: connected, sent request, received request.
Invitation / uitnodiging	A request to connect, carrying the sender’s chosen circle, an optional relation and message. Accepting creates the connection.
Relation / relatie	An optional label on a connection: parent, child, partner, sibling. Shown on both sides; triggers a confirmation when accepting because family details are usually shared more widely.
Nickname / bijnaam	A private display name the owner gives a connection (“Mum”). Only the owner sees it.
Favourite / favoriet	A pinned, reorderable connection shown at the top of Contacts.
Contact card / contactkaart	What one profile sees of another: the details the other party shared with the circle they placed you in. Stored as a snapshot on the server.
Connected service / gekoppelde dienst	An external address book the app writes contact cards into and reads contacts from: the phone’s contacts, Google Contacts, later Microsoft. Configured with the circles whose contacts it should receive.
Sync / synchronisatie	Comparing contact cards with a connected service and applying the differences. Contacts fall into buckets: to add, to update, to delete, to link, to invite, invited, in sync, hidden.
Cross-reference / vergelijken	Checking which people in a connected service already use Incico, by hashed e-mail, phone and name, and inviting them from there.
Notification / melding	An in-app and push message: invitation received or accepted, contact updated, contact removed, circle changed.
Block / blokkeren	Prevents a profile from finding, inviting or seeing you; removes any connection.

Two principles behind the terms

You never edit other people’s data. A contact card is read-only on your side; if a detail is wrong you tell the person, or they fix it themselves and it flows to you. The only things you own about a connection are its circle, relation label, nickname and favourite position.

A circle is yours, not shared. Family means your Family; the other party has their own circles and places you wherever they like. Neither side sees the other’s circle names.
