Terms of Service

By using OpenCal (“the Service”), you agree to these Terms. If you do not agree, do not use the Service. OpenCal is operated by Mark Takáč (markithe.dev). Contact: hey@markithe.dev.

OpenCal lets you create calendars and share them with secret edit and view links, without creating an account. You can also subscribe to a calendar via an ICS feed in apps such as Google Calendar, Apple Calendar, or Outlook.

The Service is provided free of charge, “as is,” and may change, break, or shut down at any time.

You agree to:

• Keep your edit and view links confidential. Possession of a link is access.
• Bookmark or otherwise save your edit link. We cannot reset or recover lost edit links.
• Only publish content you have the right to share, and not use OpenCal for unlawful, harmful, abusive, or misleading material.
• Not attempt to disrupt the Service, bypass rate limits, scrape at scale, or probe others’ calendars without authorization.
• Not upload or link malicious content, including through ICS feed URLs.

There are no user accounts, passwords, or email-based recovery. Anyone with your edit link can change or delete the calendar. Anyone with your view or feed link can read the events. Share carefully.

We may refuse, throttle, or remove calendars or traffic that we reasonably believe violate these Terms, harm the Service, or create legal risk — including spam, malware distribution, harassment, or illegal content.

The Service may rely on hosting, database, and analytics providers (for example Vercel, Supabase, and, if you consent, Google Analytics). Your use may also involve third-party calendar apps when you subscribe via ICS. Those services have their own terms and privacy practices.

OpenCal’s branding, design, and software remain ours (or our licensors’). You keep ownership of the calendar content you create. By using the Service you grant us a limited license to host, process, and display that content as needed to operate OpenCal.

To the fullest extent permitted by law, the Service is provided without warranties of any kind, express or implied — including merchantability, fitness for a particular purpose, availability, or non-infringement. We do not guarantee that calendars will never be lost, that links will remain secret if leaked, or that ICS subscriptions will sync instantly or forever.

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or goodwill, arising from your use of (or inability to use) the Service. Our total liability for any claim relating to the Service is limited to €0, since the Service is free, or the minimum amount required by applicable law if a zero cap is not allowed.

You agree to indemnify and hold us harmless from claims arising out of your content, your misuse of the Service, or your violation of these Terms or applicable law.

We may update these Terms by posting a new version with a revised “Last updated” date. Continued use after changes constitutes acceptance. We may suspend or end the Service (or your access to it) at any time.

These Terms are governed by the laws of Slovakia, without regard to conflict-of-law rules. Courts in Slovakia have exclusive jurisdiction, except where mandatory consumer protections in your country of residence say otherwise.

How we handle data is described in our Privacy Policy.
