Frequently asked questions

TeamLinkUp is a shared team calendar web app. Create master calendars with color-coded sub-calendars, share secure permission links, invite team members, sync with Google/Apple via iCal, and manage bookings — with strong security defaults.

Yes. Free includes core calendars, up to 3 sub-calendars, standard read + admin links, and essential views. Premium unlocks unlimited sub-calendars, advanced links, password protection, custom logos, and more.

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, then subscribe in Google (From URL) or Apple Calendar (New Calendar Subscription). Feeds are read-only and refresh automatically.

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.
