Frequently Asked Questions
After payment is completed for Cranium.SI, we’ll guide you through the best available transfer option based on the domain’s current registrar and extension.
For most domains, we’ll seamlessly move the domain to your Atom account. If the domain extension is not yet supported or there is an exception, we can typically assist with either a registrar account push or by providing an authorization (auth) code so you can transfer the domain to your preferred registrar.
Cranium.SI and other names on Atom Marketplace do not include Trademarks or business registration. This is because Trademarks are unique to the industry (class) as well as country of the business. Since Cranium.SI can be purchased by anyone for any use, it would not be possible for us to file a Trademark in advance.
We recommend that you do some research and/or seek legal advice to ensure that the name you are interested in does not have a direct Trademark conflict by a competitor in your industry and within your region. If there is no direct conflict, or the existing trademark is unrelated to how you plan to use it, then you have a good chance of being able to trademark the name yourself. If there is an existing trademark, keep in mind that, as long as your business is in a different industry, you may still be able to file a trademark for the name.
We also offer a Trademark validation & Filing service which includes upfront Trademark validation and filing the Trademark application on your behalf by a licensed Trademark Attorney.
Domains purchased on our platform are generally non-refundable. Because domain transfers are typically instant or near-instant, refunds cannot be issued once a domain transfer has been initiated or completed.
If a domain has not yet been transferred, a refund may be considered only if all of the following conditions are met:
If a refund is approved under these conditions, it may be subject to a cancellation fee to cover payment processing costs.
The purchase price of a domain on our marketplace is a one-time payment. Once the domain is transferred to your account, you will own it.
To keep the domain active, you’ll need to renew it each year through your domain registrar. Renewal fees vary by registrar and domain extension. For example, .com domains typically renew for around $10–$20 per year, while other extensions such as .io, .xyz, or .ai may cost more.
To avoid accidental expiration, we recommend keeping a valid credit card on file with your registrar and enabling auto-renewal so your domain renews automatically each year.
All domain purchases are backed by our Purchase Protection Guarantee. With over 100,000 customers worldwide, Atom has been featured in the Inc 5000 list of fastest growing companies for 4 consecutive years.
We initiate most domain transfers within 1 Business day of purchase. If, for any reason, we are unable to transfer the domain to your ownership, we offer a 100% refund.
Some domains on our marketplace offer Lease to Own plans, allowing you to purchase a domain through smaller monthly payments instead of paying the full amount upfront.
You can begin using the domain after your first payment. The domain will remain securely held with Atom until all payments are completed, and our team can assist with any domain setting changes while the Lease to Own plan is active.
Once the Lease to Own plan has been paid in full, the domain will be transferred to your ownership.
If your plans change, you can cancel the Lease to Own plan at any time. Learn more about how Lease to Own plans work in our detailed guide: How Lease to Own Works.
