01Current truth
Public, locally tested, and ready to sell are different states.
Public v1.2.0
Free to install from the Chrome Web Store, with a known P0 that may prevent Google Calendar detection and drag selection.
Free v1.3 candidate
Locally tested connection recovery, five starting points, three interaction modes, 30–120 minute durations, audience-aware copy, and on-device date parsing. Not in the Store release.
Plus candidate
The JAPAN Shoji test environment has verified one owner calendar via CalendarList and FreeBusy: two available and one conflicting result from three candidates. It is not ready for general use or sale.
No payment flow
There is no live Plus product, final Price, or Payment Link. Stripe sandbox purchase, refund, cancellation, restore, production authorization and readback remain open.
02How the Free workflow works
Open, select, verify, copy.
1
Open
Open desktop Google Calendar in week view and launch the SlotRelay side panel.
2
Select
Confirm JST, then manually drag over candidate ranges or enter a date and time.
3
Verify and copy
Choose audience, duration and method. Verify every date and time before copying the message.
03Plus privacy boundary
Availability only, not event contents.
The Plus candidate reads minimal CalendarList display data so the user can choose calendars, then queries FreeBusy for the selected calendar IDs and period. It does not request event titles, descriptions, locations, attendees, attachments or meeting links through the Events API. Results expire after two minutes and are rechecked before being applied to a reply in the candidate design.
An email address alone does not grant calendar access.
The other Google Calendar must have suitable sharing permission and Google must return FreeBusy. A real shared-person acceptance test has not been completed.
