Check-ins

The record that you were actually there. Added only by you, only when you went.

A public travel mark for a botanical garden in Phoenix in Discriminantly on a phone, with its map, and Directions and Check in buttons
A public travel mark with its map. Check in is the separate act that records a visit, on the day the member says they were there; Directions opens the place in a maps app. Until a check-in exists, the mark proves no visit.

What it is

Visits and experiences.

Check-ins record actual visits: a date, or a stay, and anything you want to say about it. A check-in belongs to a travel mark.

What keeping one asserts

Exactly this.

A check-in asserts a visit: a date, or a stay with a first and last day, on a travel mark, with anything you want to say about it. A visit whose date you cannot recall is recorded as a visit with an unknown date.

What it does not assert

And never implies.

It asserts nothing about liking the place, recommending it or planning to return. It is never created from a plan, a mark, a photo, a mention or an assistant’s guess.

How it relates to the others

Separate records, separate meanings.

A check-in belongs to one travel mark. Several visits to the same place are several check-ins. A plan’s stop never becomes a check-in on its own.

Where it appears

In the application.

On the mark’s page, in your activity, and in the “On this day” resurfacing when a dated visit comes round. Check-ins follow the privacy of their mark.

In the application

From the member’s own record, on a phone.

A travel mark for Hatchards bookshop on Piccadilly, London, in Discriminantly on a phone: city, address, the member’s note on why, hashtags, a link and a map
A travel mark: a London bookshop worth remembering, with its address looked up, the member’s own note on why, tags, a link and its place on the map. A mark records that a place was worth saving, not that the member went or recommends it.

With an authorized AI

Retrieved, and added, when you ask.

A connected assistant records a check-in only when you say you went. It is told that mentioning a place, or planning to go, is not a visit, and to ask rather than guess a date.

Privacy and provenance

Per record.

A check-in is as public as its mark. Deleting a check-in removes it; the history of changes keeps that it existed.

What a check-in proves, and does not

Plainly.

Proves

  • A check-in proves a visit, as you recorded it. Nothing proves a visit otherwise.

Does not prove

  • A check-in does not prove endorsement.
  • A stay of several days is one check-in with a range, not several visits.

The other records

Each with its own page.
