Frequently asked questions

TeamLinkUp is a shared team calendar. You make a calendar, add colored layers, share links, invite people, subscribe with iCal, and optionally let others book a slot.

Yes. A free account gets up to 5 layers, 5 seats, share links, the usual views, built-in skins, and the UI builder with one saved Look. Premium adds more layers, Looks, inbound iCal, a logo, notices, and a small upload library.

Not if you only open a share link. To keep a calendar you create, sign up free. Without an account the homepage demo is deleted after 7 days. Captcha and per-network limits cut spam.

A live editor for the calendar look: top bar, sidebar, canvas, layout, named Looks. Free keeps one saved Look. Saving a Look does not change calendars until you apply it.

Each link is a long random secret in the URL (/c/…). Permissions can be read-only, add-only, or admin. Only a hash of the token is stored in the database, so lost tokens cannot be reconstructed from the server.

Yes. Create an iCal feed under Manage → Sync & backup and subscribe in Google (From URL) or Apple (New Calendar Subscription). That shows up as a separate calendar in those apps. TeamLinkUp never writes into your existing Google or Apple calendar. To copy events into TeamLinkUp, import a .ics file (preview first) or, on Premium, paste their secret iCal URL onto an Imported layer.

No. We only publish a read-only feed they pull, or we pull their public/secret URL into TeamLinkUp. We do not use Google/Apple write APIs. Imports merge; they never replace a whole calendar. A failed inbound pull leaves existing events in place.

From Manage → Teams & invites, enter their email and role. They receive a link to accept. They can sign up or log in with that email. You can also share a public link without requiring an account.

We use PDO prepared statements (SQL injection protection), CSRF tokens, rate limiting, optional Cloudflare Turnstile, password hashing, optional TOTP 2FA, and security audit logging. Public IDs use UUIDs/hashes rather than sequential integers.

When enabled on a calendar, visitors can open /book/{token} and request a time slot. TeamLinkUp checks for conflicts with existing events and notifies the calendar owner.

Use a read share token with the embed URL: /embed/{token}. Copy the iframe snippet from Manage → Booking & embed.

That usually means the share link is invalid, revoked, or your account does not have team permission. Open the calendar from Dashboard → Open (for calendars you own or were invited to), or create a new share link under Manage → Share links. This is an app permission check, not always a server file permission issue.
