hello@onthree.appOnThree is a schedule publishing tool. You create schedules, add events, and share a public link. Anyone with the link can subscribe to your schedule in Apple Calendar, Google Calendar, Outlook, or any app that supports calendar feeds.
We built OnThree to be straightforward, and we try to apply that same standard to how we handle your data.
Account information. When you sign up, we collect your email address. We use Clerk to handle authentication. Your password is never stored by OnThree directly.
Schedule data. Everything you create in OnThree (schedule names, descriptions, event titles, dates, times, locations, and notes) is stored in our database so we can provide the service.
Natural language input. When you type a command to add or edit events, that text is sent to Anthropic's Claude API to parse your intent. Anthropic processes this data subject to their own privacy policy.
Usage data. We collect basic server logs (IP addresses, request timestamps, error reports) to keep the service running reliably. We don't use third-party analytics trackers.
We use the data we collect exclusively to operate OnThree:
We do not sell your data. We do not use your data for advertising.
When you publish a schedule, it becomes publicly accessible. Anyone with the link can view your schedule page and subscribe to the calendar feed. The feed includes all event data you've entered: titles, dates, times, and locations.
If you mark a schedule as private and set a password, it is not publicly accessible without that password. The calendar feed is still technically accessible via URL, so avoid putting sensitive information in event details if you're concerned about unauthorized access.
We keep your data for as long as your account is active. If you delete a schedule, it is removed from our database. If you close your account, your schedules and events are deleted. We may retain anonymized usage logs for a limited period for operational purposes.
You can request a copy of your data, correction of inaccurate data, or deletion of your account and all associated data at any time by emailing us at hello@onthree.app.
If you're in the EU or UK, you have additional rights under GDPR, including the right to lodge a complaint with your local supervisory authority.
If you have any questions about how we handle your data, email us at hello@onthree.app. We'll respond within a few business days.
OnThree lets you create, manage, and publish event schedules that others can subscribe to via standard calendar applications. By creating an account and using OnThree, you agree to these terms.
OnThree is operated by OnThree. References to "we," "us," or "our" mean OnThree. References to "you" mean the person using the service.
You must be at least 13 years old to use OnThree. By creating an account, you confirm you meet this requirement.
You're responsible for maintaining the security of your account. Don't share your login credentials. If you believe your account has been compromised, contact us immediately at hello@onthree.app.
You own the schedules and events you create. By using OnThree, you grant us a limited license to store, serve, and transmit your content solely to provide the service (for example, to serve your calendar feed to subscribers).
You're responsible for the content you publish. Don't publish schedules that are misleading, contain illegal content, or infringe on the rights of others.
When you publish a schedule, you understand that it becomes publicly accessible. Subscribers who add your feed to their calendar will receive updates automatically when you make changes. You can unpublish a schedule at any time, but we can't guarantee that subscribers' calendars will immediately reflect that change; calendar apps control their own sync frequency.
You may not use OnThree to:
We reserve the right to suspend or terminate accounts that violate these terms.
OnThree offers a free plan that allows up to 25 upcoming events across all your schedules. Paid plans with higher limits may be offered in the future. We'll give you reasonable notice before making any changes to what's included in the free plan.
Paid plan details, pricing, and billing terms will be presented at the time of purchase.
We work hard to keep OnThree available, but we don't guarantee uninterrupted uptime. We may occasionally need to take the service offline for maintenance. We're not liable for losses arising from downtime or service disruptions.
OnThree is provided "as is" without warranties of any kind. We don't guarantee that the service will be error-free or that your data will never be lost, though we take reasonable precautions.
To the fullest extent permitted by law, our total liability to you for any claim arising from your use of OnThree is limited to the amount you paid us in the 12 months preceding the claim, or $10, whichever is greater.
We may update these terms from time to time. When we do, we'll update the effective date at the top of this page. If the changes are material, we'll notify you by email. Continued use of OnThree after changes take effect means you accept the updated terms.
These terms are governed by the laws of the State of California, without regard to its conflict of law provisions. Any disputes will be resolved in the courts of San Diego County, California.
