What is Kerux?
Kerux turns a list of events into a shareable page with a QR code and one-tap subscribe. Share it once — when you change a date, everyone's calendar updates too.
Do people need an app or account to subscribe?
No. Subscribing works with Apple Calendar, Google, and Outlook through a standard calendar feed — no app and no sign-up for your audience.
What can I import?
CSV, Excel, Word, ICS, and Markdown files, or add events by hand. On Premium you can also add them by voice or from a photo.
Is it free?
Yes. The free plan covers 2 calendars with unlimited events. Premium adds unlimited calendars, no watermark, scan analytics, and AI import.
Can I edit events after sharing?
Yes. Edit anytime and save — anyone subscribed to your calendar gets the change automatically, with nothing to re-share.
How big should I print the QR code?
At least 2 × 2 cm (0.8 × 0.8 in). Bigger is better on posters — the more room it has, the more reliably phones scan it.
How much is Premium, and how do I cancel?
Premium is €35 a year or €8 a month. Cancel anytime from Subscription — you keep Premium until the end of the period you paid for.
Is my data private?
Your calendar is public only at the link you share. See our Privacy Policy for how we handle your account and event data.
