Terms of Service
Effective August 9, 2026
Acceptance
These terms are an agreement between you and Intrahold Ventures LLC, which operates Constian™. By using the Constian app, your account, or our services, you agree to them. Purchases of Constian products are also governed by our Terms of Sale, and your personal data by our Privacy Policy. If you do not agree, please do not use them.
Eligibility
You must be at least 13 years old to hold a Constian account and use the app. To buy from us, you must be at least 18 years old and able to form a binding contract. Constian is sold and supported in the United States.
What Constian is
Constian has a few parts that work together but are separate: the sign (the physical device you buy), the app (free, for iOS and Android), your account, our cloud service, and the firmware that runs on the sign.
The sign does not work anything out on its own. Our cloud service reads the due dates on the tasks the sign shows, decides the sign's color, and sends that color to the sign. This means the sign depends on the app, your account, and our cloud service to work. If any of them is unavailable, the sign may not update until service is restored.
Accounts
You use an app account to keep your tasks and to join spaces shared with you, and you may keep a separate account for the store. Your app account can be anonymous or linked to an email so you can restore it; an anonymous account has no email attached, which means we cannot recover it if you lose the device. A shared space needs a real account, because a shared space is built on knowing who did what. You are responsible for keeping your credentials secure, for activity under your account, and for providing accurate information.
Your license to the app and firmware
We give you a personal, limited, non-exclusive, non-transferable, and revocable license to use the Constian app and the firmware on a sign you own, for your own use. You may not copy, sell, rent, or redistribute them, reverse engineer, modify, or tamper with them, or use them to build a competing product. We and our licensors keep all rights not expressly granted.
Firmware and updates
Your sign runs firmware that we may update automatically over the internet to fix issues, improve it, or keep it working with our service. By using the sign you agree to receive these updates, and you understand that an update may be needed for the sign to keep functioning with the service.
The service and its availability
The service, including the app and the cloud that decides the sign's color, is provided on an “as is” and “as available” basis. We may change, limit, or discontinue features, and there may be interruptions or downtime.
Please do not rely on Constian for anything where a missed notification would be dangerous. It is a task app. It is not a medical reminder system, not a safety system, and not an alarm. Notifications depend on your phone, your network, and services we do not control, and a color on a wall is not a guarantee that anyone has read it.
Acceptable use
Please use Constian lawfully and as intended. Do not try to gain unauthorized access to our systems or another person's account, interfere with or overload the service, reverse engineer or tamper with the sign or firmware, resell access to the service, or use it for anything unlawful. We may limit or suspend access to protect the service or other users.
Buying a sign
Purchases of Constian products, including orders, prices, payment, taxes, shipping, and title, are governed by our Terms of Sale. Returns and cancellations are covered by our Shipping & Returns policy, and the sign by our Limited Warranty. Except for that limited warranty, the sign and services are provided without other warranties, to the fullest extent the law allows.
Intellectual property
The Constian name, logo, website, app, firmware, content, and product designs are owned by us or our licensors and are protected by law. You may not copy or use them without our permission, except as needed to use Constian normally.
Feedback
If you send us ideas or suggestions, we may use them to improve Constian without any obligation to you.
Disclaimers & liability
To the fullest extent permitted by law, Constian and everything we provide are offered on an “as is” and “as available” basis, without warranties beyond the limited warranty on the sign. We are not liable for indirect, incidental, or consequential losses, and our total liability is limited to the amount you paid for your sign. Nothing here limits any liability that cannot be limited by law.
Termination
You can stop using Constian at any time and delete your account from the app or the Account page. We may suspend or end your access to the app, account, or service if you break these terms or to protect the service. Your sign is yours to keep, but it may lose features that depend on your account or our cloud service if your access ends or the service is discontinued.
Changes to these terms
We may update these terms from time to time. When we do, the effective date above will change, and we will highlight significant changes where reasonable. Continuing to use Constian after that means you accept the updated terms.
Governing law
These terms are governed by the laws of the State of Illinois, without regard to conflict-of-laws rules.
