Part of the Prism suite · In development · Apple platforms

A calendar that has your back.

Not a meeting scheduler. Not enterprise calendaring. A calm, private companion that protects your time, confirms follow-ups, and makes sure the commitments you actually care about get room to happen.

01  ·  Why

Commitment over clutter.

Apple Calendar shows you everything. prismCal shows you what deserves time. The day starts with what needs attention, not a grid of colour-coded obligations you've already agreed to.

01
Protect time
Focus blocks aren't a productivity gimmick here — they're first-class commitments with their own surface.
02
Planning becomes action
A scheduled commitment can spawn a prep task or a note without you leaving the calendar.
03
Follow-through, not guilt
Missed something? prismCal rolls it forward cleanly. No angry red badges. No inbox of shame.
04
Private by default
Calendar data reveals who you meet, where you are, and when. We refuse to build a business on any of that.
02  ·  How it feels

Four calm moments in a day.

01
Open
See what needs attention today — not every meeting ever, just the ones you still have to decide something about.
02
Protect
Confirm follow-ups, carve out focus time, or gently adjust one commitment. No drag-drop puzzles.
03
Link (optional)
Attach a note from prismNotebook or a person from prismContact — context becomes part of the commitment.
04
Move on
Close the app. Live the day. The calendar will still be here when you come back.
03  ·  The Prism suite

Time is where everything else lands.

prismCal is the “where” and “when” of the suite. It reads suite references from prismNotebook, prismContact, and prismTask — so a meeting already knows the prep notes and the follow-ups that belong to it.

prismNotebook
Notes that stay connected to what they mean. Meeting prep continues where you left off.
prismnotebook.app →
prismContact
Contacts that help you remember people. Events know who's in the room.
prismcontact.app →
prismTask
Follow-through without guilt. Scheduled tasks get real time blocks here.
prismtask.net →
LaClair Technologies
The studio behind the suite. Independent, privacy-first, built to last.
laclairtech.com →

Shared app group group.com.laclairtech.prism.shared and iCloud container iCloud.com.laclairtech.prism.shared carry suite references only — your event and planning data stays with prismCal.

04  ·  Privacy, plainly

Your calendar is nobody else's business.

prismCal reads the calendars you authorize through Apple's EventKit, on-device. Nothing is uploaded, analyzed in the cloud, or shared beyond the sync you already use through your own iCloud or provider accounts.
