Terms of Service

Effective September 30, 2026

The short version

  • Yearmark is $5 a month or $36 a year, and one plan covers your household.
  • Your subscription renews automatically until you cancel, and you can cancel anytime.
  • Your year belongs to you. We just store it and show it back to you.
  • AI assistants can make mistakes, so check what they add.

These terms are an agreement between you and Riley AI Systems ("Yearmark," "we," "us") for your use of yearmarkcalendar.com, app.yearmarkcalendar.com and the Yearmark connector. By creating an account or using Yearmark, you agree to them.

Your account

You need to be at least 18 to create an account and pay for a plan. Keep your sign-in details safe, and let us know right away if you think someone else has access. You're responsible for what happens under your account.

Households

One plan covers your household. The person who pays is the plan owner and can invite and remove members. Everyone in a household can see and edit the shared year. The plan owner is responsible for the people they invite.

Plans and billing

Refunds are covered in our Refund Policy.

Your content

Everything you add to Yearmark belongs to you. You give us permission to store, process and display it only as needed to run Yearmark for you and your household. You can export or delete it anytime.

AI connections

You can connect Yearmark to an AI assistant of your choice. When you do, the assistant acts on your instructions and can read, add and change blocks in your year. AI assistants can misunderstand or make mistakes, so review what they add. We aren't responsible for the assistant itself, which is provided by another company under its own terms.

Acceptable use

Don't use Yearmark to break the law, harm others, or interfere with the service. That includes trying to access other people's accounts, overloading or reverse engineering our systems, or reselling Yearmark without our permission. We may suspend accounts that do.

New features

Some features may be marked as early or coming soon. They may change or go away as we learn what works.

Ending your account

You can close your account anytime. We may suspend or close an account that breaks these terms, and we'll tell you why when we can. If we ever shut Yearmark down, we'll give you at least 30 days notice to export your year and refund any unused time on a yearly plan.

Disclaimers

Yearmark is provided "as is." We work hard to keep it running and accurate, but we can't promise it will always be available or error free. Yearmark is a planning tool, so don't rely on it alone for anything where a missed date could cause serious harm.

Limit of liability

To the extent the law allows, we aren't liable for indirect or consequential losses, like lost profits or data, and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim.

Governing law

These terms are governed by the laws of the State of North Dakota. Any dispute will be handled in the state or federal courts in Cass County, North Dakota.

Changes

If we change these terms in a meaningful way, we'll email you before the change takes effect. Continuing to use Yearmark after that means you accept the new terms.
