What it is

Your diary here and your own Google or Microsoft 365 calendar, kept in step both ways. Each person connects their own calendar with the provider’s own sign-in — the password never reaches this system — and chooses which of their calendars to use. A booking in your diary appears there within a minute or two, moves when the appointment moves and disappears when it is cancelled. Busy time you add there — a meeting, a school run, a day out of office — comes back every five minutes and closes those slots here, so nobody books a patient into it. By default the event says only “Appointment”; you can choose to show the patient’s first name, and nothing more is ever sent — no surname, no reason, no diagnosis. The sign-in is sealed with the same envelope that protects every other key on the platform, a refused or withdrawn sign-in stops the sync and tells you, and disconnecting takes the events back out and erases the sealed sign-in on the spot. It works once the platform has been registered with Google and Microsoft; until then the Connect button says so.

Who uses it: Built for: Every specialty
Reads: Your own diary’s appointment times, busy time in the calendar you connect — never event titles or who else is invited, the patient’s first name, only if you turn that on
Writes: Private “Appointment” events in your own calendar, busy blocks in your diary, the connection record
Never: It never turns something in your calendar into a patient booking, and it never settles a clash on its own — busy time over an existing appointment is counted and shown to you, and the appointment stays where it is.
Access: Only people whose role includes it — the clinic owner decides who
Your data: PHI-lite. Hosted in Boston, United States. On uninstall: Sync stops. Disconnecting first takes the appointments back out of your calendar and lifts every busy block from your diary; the sealed sign-in is useless either way, because it is bound to the account that made it.

How it works

Connect your calendarChoose Google or Microsoft 365 and sign in on their page. You allow access to your calendar only — not your mail or files.
Pick the calendar and what it may sayChoose which of your calendars gets the appointments, and whether an event shows the patient’s first name or just “Appointment”.
Both calendars stay in stepBookings appear there, busy time there closes slots here, and the screen shows when it last synced and anything that went wrong.

Rules it keeps

What it does not do, by design. A listing with only benefits is an advertisement.

It never sends a diagnosis, a reason for the visit or a surname, and it never shows your calendar to anyone else in the clinic.

Questions clinics ask

What does CalendarSync do?

Two-way sync with Google Calendar and Microsoft 365 — not just a read-only feed. Your diary here and your own Google or Microsoft 365 calendar, kept in step both ways. Each person connects their own calendar with the provider’s own sign-in — the password never reaches this system — and chooses which of their calendars to use. A booking in your diary appears there within a minute or two, moves when the appointment moves and disappears when it is cancelled. Busy time you add there — a meeting, a school run, a day out of office — comes back every five minutes and closes those slots here, so nobody books a patient into it. By default the event says only “Appointment”; you can choose to show the patient’s first name, and nothing more is ever sent — no surname, no reason, no diagnosis. The sign-in is sealed with the same envelope that protects every other key on the platform, a refused or withdrawn sign-in stops the sync and tells you, and disconnecting takes the events back out and erases the sealed sign-in on the spot. It works once the platform has been registered with Google and Microsoft; until then the Connect button says so.

What data does CalendarSync read and write?

CalendarSync reads your own diary’s appointment times, busy time in the calendar you connect — never event titles or who else is invited, the patient’s first name, only if you turn that on and writes private “Appointment” events in your own calendar, busy blocks in your diary, the connection record. Its data class is PHI-lite. Every app works on the same patient record — nothing is copied into a silo.

What does CalendarSync deliberately not do?

It never turns something in your calendar into a patient booking, and it never settles a clash on its own — busy time over an existing appointment is counted and shown to you, and the appointment stays where it is. It never sends a diagnosis, a reason for the visit or a surname, and it never shows your calendar to anyone else in the clinic.

What happens to our data if we uninstall CalendarSync?

Sync stops. Disconnecting first takes the appointments back out of your calendar and lifts every busy block from your diary; the sealed sign-in is useless either way, because it is bound to the account that made it.
