What's new in LockMyCal

v1.22.0 STABLE October 4, 2026 +

New Features

• Saved locations: A new Locations page with your meeting places: add, edit, delete and reorder them by dragging, each showing how many meeting types offer it. Before you delete a location a meeting type uses, the app warns you.
• Choosing a location when booking: An in-person meeting can offer one or more saved locations, and you create a new one right in the meeting type. With several, the guest picks one; with none, they learn that you will arrange the address after booking, and the emails say so.
• Location on reschedule: A rescheduled meeting stays at its location, or the guest picks another of those offered.
• Existing in-person addresses are turned into saved locations automatically; a meeting type card shows the location's name or how many it offers.
• Bookings in your own calendar too: When you book a meeting on someone else's booking page while signed in, it is also saved to your default calendar. The form asks, and can remember your choice; the copy moves and is cancelled along with the meeting. Signed-out visitors are offered to sign in and are brought back to the same time slot afterwards.
• Default calendar: On the Calendars page you set which calendar is your default; for an account with several calendars you pick one of them. The Your bookings on other pages setting decides whether to ask each time, always save, or never.
• Your contact details: In a meeting type's Booking Rules you decide whether a signed-in booker sees your email and phone; by default they see only your name.

Enhancements

• A meeting you booked with someone else shows on your dashboard from your side: under the host's name, with the attendee's join link and the Awaiting host approval badge; only the host can approve it.
• A new look of the app in LockMyCal colours and fonts (Schibsted Grotesk and IBM Plex Mono), including dark mode and the sign-in page background.
• On short windows (a phone in landscape) the booking page hides the footer and slims the top bar, so the buttons stay visible.
• A refused image is reported as too large, and removing its metadata keeps its quality.

Security

• A narrower Content-Security-Policy and reCAPTCHA loaded only once a form is being filled in; when Google cannot be reached, bookings and sign-ups go through. Cloudflare Turnstile still refuses during an outage.
• Location and device details are removed from uploaded avatars and backgrounds.
• Calendar files for guests no longer contain the booker's private details.
• Webhook URLs, custom meeting links and secrets are stored encrypted; poll, RSVP, free/busy and Telegram links as hashes; going back to an older version no longer brings back replaced links and secrets.
• Analytics without reversible visitor hashes, ad click identifiers or links carrying tokens; IP addresses, unverified accounts and payment records are kept for a shorter time.
• Email recipients and subjects are not written to the log; links in emails are not rewritten for click tracking; the app no longer connects to data.iana.org.

Bug Fixes

• Submitting a form no longer hangs when the reCAPTCHA check stalls.
• Czech and other accented characters no longer turn into garbage in events written to CalDAV calendars (e.g. Radicale).
• Edits in the dashboard calendar are not overwritten or written twice, even with several tabs open or after reconnecting.
• When a booking is rescheduled, details you added to the event in a CalDAV calendar are kept; a deleted event is recreated.
• The Show these bookings as free on my calendar switch of a meeting type is saved.
• Correct booking times for Manitoba and the Northwest Territories.
• Events from a calendar without its own colour have readable text.

v1.21.0 STABLE October 2, 2026 +

New Features

• Polish: Polish is now a supported language of the interface, the booking pages and the emails (alongside English, Czech, German, French, Italian and Ukrainian).
• Contacts export: The Export CSV button on the Contacts page downloads the contacts (name, email, phone, company, note) to a CSV file; with a search filled in, only the matching ones.

Enhancements

• New event dialogs in the calendar: the title in the header, Event / Meeting tabs, calendar and video chosen from a dropdown, reminders added with the “+” button; the title of a new event is required.
• A three-way appearance switch (light / system / dark) in the top bar and links to the documentation and the website.
• The Overview also shows requests awaiting approval, and a click opens the meeting in the calendar; the meeting card lists its reminders.
• The “View full calendar” button sits at the top right of the booking page (Quill and Rhythm).
• The default schedule and meeting types of a new account are named in the user's language.
• The public calendar shows only Monday to Friday by default (the Show weekends option); the current day is highlighted with a colour across the whole day in the calendars.
• A booking's title is stored in the organiser's language and shown to guests in their language in emails.
• Booking pages and emails no longer load fonts from Google.
• On Cloudron, the sign-in button carries the name of your identity provider.
• The logo in the top bar of the booking pages links to the organiser's booking page; the footer of the dashboard and the booking pages shows “Powered by LockMyCal · v” and a “Report a bug” link (it leads to the website's forum).
• Rescheduling a booking also moves the event in iCloud; mailbox.org no longer adds your login address to bookings.
• Dates in the dashboard calendar are written in each language's own order; month headings are capitalised and in their standalone form.
• A URL with a trailing slash redirects to the slashless address; screen readers announce required fields.
• An event written to a connected calendar has its own UID, so the cancel and reschedule links stay safe.

Bug Fixes

• Choosing when a recurrence ends (“Ends after” / “Ends on”) no longer jumps back to “Never ends”.
• The public calendar of an organiser with the Rhythm theme renders correctly.

SAAS

• Pro+ – your own calendar: An add-on to paid Pro (€2 / CZK 50 / $3 per month) – an independent calendar hosted in the EU, connected to your bookings and available in Outlook, Apple Calendar, Android and on the web. Guide
• The Pro plan now lets you connect up to 6 calendars.
• A "Your current plan" card on the Overview.

v1.20.0 STABLE September 29, 2026 +

New Features

• Adding a guest to a booking: The Add guest button on the meeting card invites more people to an existing booking.
• Quick add of a meeting: Now with a note for the guest, extra guests and a choice of the invitation language.
• Reminders on the booking card: The meeting card lists its reminders.

Enhancements

• The number of meetings created with quick add is limited to 20 per 10 minutes per user.
• Quick add no longer sends a reminder nobody asked for.
• With CalDAV, events from the calendar grid are saved to the calendar you picked.
• An event's video room is kept when you move it to another calendar.

Bug Fixes

• The video room of a deleted event is deleted even with shared calendars.
• The missing “in” is back in the attendee reminder subject.

v1.19.0 STABLE September 29, 2026 +

New Features

• Recurring events: In the calendar on your dashboard you edit or delete just one event, this and the following, or the whole series (CalDAV, Google, Outlook); a series can be split.
• Moving a series: You move a whole recurring event to another calendar.
• Error tracking: Errors, crashes and failed jobs are stored in the application's database (nothing is sent to third parties) and the administrator gets an email about a new or returning error; it can be switched off with the ERROR_TRACKING_ENABLED variable.

Enhancements

• Attendees get a cancellation when you delete an event, and a notice when the time of a recurring event changes.
• A burst of new errors reaches the administrator as one roll-up email.
• Admin alerts keep being retried until the mail server recovers; an error is logged when there is no recipient.
• Alerts about disputes and calendar sync show the real reason and keep calendar owners' email addresses out.
• Provider logos stay sharp at every size and screen density.

Security

• Booking cancel links are no longer exposed in calendar events.
• Meeting links and poll tokens are kept out of the request log.
• Deleting someone else's event never sends a cancellation.

Bug Fixes

• Google: recurring events show every occurrence, including series changed after setup; events already deleted are no longer shown.
• CalDAV: a moved occurrence no longer also shows at its old time; details the grid doesn't show are kept when editing.
• Quick successive edits of one event are applied in order.
• A CalDAV outage no longer raises an alert on every sync cycle.
• The icons in Quill's booking confirmation rows are centred.

Enhancements

• Phone meeting notification emails now explicitly display the phone number to call.
• Application follows browser locale; reminder durations format in reader language.
• Refined Polish and Ukrainian translations; accessible keyboard navigation for location selection in the Rhythm theme.

Security

• Disabled accounts remain strictly locked out during Google, GitHub, and OIDC authentications.

Bug Fixes

• Fixes for Microsoft Teams meetings (missing join link, duplicated events in Outlook).
• Outlook sync improvements: no crashes on rejected requests, push subscriptions renew in place.
• Large CalDAV calendars no longer cause memory spikes; edits and deletions on default calendars sync correctly.
• Quick-add guests receive a single invitation instead of two; guests can no longer reply to past or canceled appointments.
• Recovered background jobs do not re-send emails and webhooks; meeting polls cannot be finalized on time-off days.
