iDentiCal is a Windows Service that syncs OpenDental appointments to each dentist's calendar — 24/7, runs locally, no cloud middleman. Buy it once for £249.99. It's yours for life. No "plugin expired" lockouts.
Not a browser extension. Not a brittle plugin. A proper Windows Service designed for practices that need sync to just work.
Runs as a Windows Service from boot. Syncing continues at 3am, on weekends, and after the reception PC is locked.
Polls every 60 seconds by default. Adds, moves, and cancellations land on the dentist's phone in under a minute.
Credentials and OAuth tokens are encrypted at rest with Windows DPAPI. Service↔tray comms protected by local admin token.
Exponential backoff, transient error detection. A patchy internet day will not break your day.
Each dentist gets their own sync target and Google account. Multi-location practices isolate calendars per clinic.
The service runs on your PC or server. Appointment data goes directly from your network to Google.
There's nothing to babysit, no dashboard to check. Appointments simply appear on each dentist's Google Calendar — formatted as initials and patient number for privacy.
Initials + patient number — no clinical details, no operatory, nothing that leaks beyond what you choose to share.
Built for reliability — not for demos. Compare the day-to-day reality.
One PC/server. One installer. Three steps. Then forget it exists.
Download the signed installer (.exe), run it on your practice PC or server. The Windows Service installs and starts under LocalSystem, ready to run at every boot.
Point iDentiCal at your OpenDental MySQL database (read-only user), then sign each dentist into their own Google account. Pick a title format and time window.
Within the first poll cycle, appointments populate each dentist's Google Calendar. From now on, every change made in OpenDental syncs across automatically.
iDentiCal is engineered for clinics that take patient data seriously. No plain-text secrets, no write access to OpenDental.
OAuth tokens and DB credentials encrypted with Windows DPAPI, scoped to the LocalSystem account. Never readable as plain text on disk.
Connects with a read-only MySQL user. iDentiCal cannot write, alter, or delete a single row in OpenDental — by design.
Appointment data goes directly from your network to Google over HTTPS. Nothing is mirrored, cached.
Structured rotating logs redact patient identifiers, tokens, and connection strings automatically.
We request the smallest set of OAuth scopes Google offers for this job: calendar.events.owned (only the events we create), calendar.calendarlist.readonly (to let you pick a calendar at setup), and openid + userinfo.email (to verify the right Google account is still attached). No Drive, no Contacts, no Gmail. Full scope breakdown →
Buy iDentiCal once. It's yours — for life. No subscription traps. No "plugin expired" lockouts. Your first year of support & updates is included. After that, support is £49.99/year — entirely optional, and less than half what competitors charge.
Most OpenDental sync plugins are subscription-only — typically £139/year, forever. Here's how iDentiCal compares.
Break even by year 3. Pure savings every year after. Skip the £49.99 support fee and you're £445 ahead by year 5
