Frequently Asked Questions
Answers to common questions about links, quotas, and accounts
Do the calendar links expire?
Standard generated links never expire because all event parameters are self-contained in the URL. Trackable Pro links remain active throughout your subscription.
Can I edit an event after sharing the link?
Yes! If you created the event under a Pro or Business account, you can update times, locations, or descriptions anytime from your dashboard. The public page and short links update dynamically.
What is the difference between Pro and Business?
Pro (9€/mo) is designed for event creators (analytics, QR codes, branding, 3,000 adds/mo). Business (19€/mo) is built for SaaS and developers needing full REST API access (10,000 req/mo), 100% whitelabeling, and CSV exports.
