Version 2026-10-07. For a Host or a Renter who had an account before that date, it applies from November 9, 2026, or from the day they accept it if that is later (section 14).
These marketplace terms ("Terms") apply whenever you list a machine on the Primcast GPU marketplace or rent one from it. The marketplace is operated by Primcast LLC ("Primcast", "we", "us", "our").
They add to our Terms of Service, Refund Policy and Privacy Policy, which also apply. Where they differ on the marketplace, these Terms govern.
By registering a machine with the agent, publishing a listing, paying for a rental or adding funds to a marketplace balance, you agree to these Terms. This is how these Terms are first accepted. A later version applies to you only as section 14 says: registering a Machine, listing, paying or going on using a Rental does not by itself accept it. You must be at least 18 years old, and able to enter into a binding contract, to list a Machine or rent one.
Primcast operates the marketplace: the listings, the Agent, the Relay, the Renter's billing and the Host's payouts. Primcast rents the computing capacity of a listed Machine from its Host and supplies Rentals to Renters in its own name: it bills the Renter and pays the Host rent. Primcast may also supply that capacity through its affiliate Data Room, Inc., which then supplies the Rental to its own Renter in its own name. Either way, Primcast pays the Host rent under these Terms.
Primcast does not own, possess, house, power or maintain a Host's Machine, and does not supply its internet connection. The computing capacity Primcast supplies in a Rental comes from the Host's Machine.
Nothing in these Terms makes a Host an employee, agent or partner of Primcast, or a Renter a customer of the Host. A Renter's contract for a Rental is with Primcast, or with Data Room, Inc. when Data Room, Inc. supplies the Rental, and never with the Host.
Only a Host that has completed identity verification (section 9) can register or list a Machine. By listing a Machine the Host confirms that:
A Machine is offered to Renters only while it passes the Agent's hosting checks and is online. The Host sets the monthly rent it is paid for its Machine and may also set an hourly, a daily and a weekly rent. A period with no rent is not offered, and a shorter period may not cost more than a longer one. Primcast sets the prices Renters pay. The Host may change its rents, pause the listing or remove the Machine at any time when it is not rented. A change does not affect a period already paid for.
A Host should keep a rented Machine online, powered and connected for the whole Rental. Time during which a rented Machine is offline or unavailable earns nothing and may be refunded to the Renter. Primcast may remove a listing that is repeatedly unavailable while rented.
The Agent runs with administrator (root) rights on the Machine, because creating a Rental, loading firewall rules and creating an encrypted volume require them. It makes one outbound connection to the Relay and opens no port on the Host's network. It gives nobody at Primcast a shell, a login or file access on the Machine.
The Agent installs the software it needs to host a Rental, runs test rentals, measures the Machine and its connection, reports the results and problems to Primcast, and keeps itself up to date. Its source code and a description of everything it does on a Machine are published with it, under the license stated there.
The Host may stop or remove the Agent at any time. Removing it during a Rental ends that Rental and is treated as the Machine being unavailable.
Suggestions about the Agent, and code a Host or Renter sends Primcast for it other than through the Agent's public repository, are feedback under section 13 of the Terms of Service. Code contributed through the repository is licensed under the license published there. The Agent's automatic reports described above are not feedback.
Each Rental runs in its own virtual machine, or on a machine whose GPU cannot be passed to a virtual machine, in a hardened container in which the Renter is an ordinary user. The Renter does not receive a login to the Host's operating system, its firmware or its management interface.
Before a Rental starts, the Agent loads and verifies firewall rules that block the Rental from the Host's local network, from every network configured on the Machine, from private address ranges and from the Machine itself. If the rules cannot be verified, the Rental does not start.
The Renter's data is written to an encrypted volume whose key exists only in memory. When the Rental ends, the Agent removes the Rental, destroys the key and checks the GPU. A Machine whose cleanup cannot be verified is taken off the marketplace until it has been checked.
Where the Agent and the hardware support it, the Agent reads the state of the Machine's hardware before and after a Rental: the versions and settings of each rented GPU's firmware, its error counters, the wear figures of the drive that holds the Rental, and how much the Rental wrote to its disk. A value that cannot be read is marked as such, and a Machine on an older Agent makes no reading. It reads nothing of what the Renter stores, runs or sends. The Host can see the readings of its Machine, and a Renter can ask Primcast's support for the reading of its own Rental. It is used to notice a change to a Machine and as evidence in a claim under section 10. It is a measurement reported by a Machine that its Host controls: it can be incomplete or wrong, and a difference between the two readings does not by itself show that anyone did anything.
These are technical measures, not a guarantee. No isolation is perfect, and Primcast does not warrant that a Rental cannot affect a Machine or that a Machine cannot affect a Rental.
A Rental reaches the internet through the Host's own connection, from the Host's public IP address. Primcast does not filter, inspect or monitor that traffic.
The Host accepts that activity of a Renter may be attributed to the Host's IP address by third parties. A Host may apply its own filtering on its network, such as blocking outbound mail, as long as the ordinary use of a Rental (SSH through the Relay, software downloads, access to public services) keeps working.
On the Host's request, Primcast will confirm in writing that a Machine was rented through the marketplace during a stated period, so that the Host can answer a complaint made against its IP address.
Primcast may withhold, reduce or recover a Host's earnings only for a Rental affected by the Host's own breach of these Terms, by fraud in which the Host took part, or by its Machine being unavailable, and only for the amount that the breach, the fraud or the unavailable time accounts for. A Renter's refund, chargeback or payment dispute is otherwise Primcast's loss and does not reduce the Host's earnings. Before withholding or recovering earnings, Primcast emails the Host the Rental, the amount, the reason, the evidence it relies on and the day the withholding would take effect, which is at least 14 days later. The Host may challenge it by replying within those 14 days. Nothing is withheld during them, and where the Host has challenged in time, nothing is withheld until Primcast has answered the challenge. The answer comes from a person who did not propose the withholding, within 30 days of the challenge; where more time is needed, Primcast tells the Host before those 30 days end, saying why and the date by which it will answer. The answer deals with the Host's evidence and objections and gives its reasons. Where a challenge succeeds, in whole or in part, the earnings concerned go into the next monthly payout sent after the answer, with no minimum amount, also where the Host has no other earnings or its account has been closed. If the law or the payment provider stops that payout, Primcast tells the Host why and what is needed, and sends it as soon as it can. A Host that points to a mistake or brings new evidence may ask for the answer to be looked at again, and none of this limits the Host's rights under section 14. Earnings already paid are recovered only by deducting them from the Host's later payouts.
The Host is responsible for all taxes on its earnings and for any registration, invoicing or reporting its own law requires.
Payment processing services for Hosts on Primcast are provided by Stripe and are subject to the Stripe Connected Account Agreement, which includes the Stripe Terms of Service (collectively, the "Stripe Services Agreement"). By agreeing to these Terms or continuing to operate as a Host on Primcast, you agree to be bound by the Stripe Services Agreement, as the same might be modified by Stripe from time to time. As a condition of Primcast enabling payment processing services through Stripe, you agree to provide Primcast accurate and complete information about you and your business, and you authorize Primcast to share it and transaction information related to your use of the payment processing services provided by Stripe. Information about Stripe's acquiring partners is in Stripe's acquirer disclosure.
Section 3 of the Terms of Service (limitations and acceptable use) applies to every Rental. In addition, a Renter must not:
Identity verification is required of everyone on the marketplace. A Host must verify its identity before it can register or list a Machine, either through the payout setup of our payment provider, which also verifies the bank account the Host is paid to, or through Primcast's own identity verification; every Host completes the payment provider's payout setup before its first payout. A Renter must verify its identity, through Primcast's own identity verification or through the payment provider's payout setup completed on the same account, before it can place an order for a Rental, whether it is paid by invoice or from the Balance. A company verifies the company and the person acting for it. Primcast may ask for verification again when account details change or a review calls for it.
Hosts and Renters must comply with United States export control and sanctions laws, including the Export Administration Regulations and the regulations administered by the Office of Foreign Assets Control, and with those of their own country. No one may list a Machine, rent one or use a Rental if they are located in, ordinarily resident in, or acting for a person in a country or region subject to comprehensive United States sanctions, or if they appear on a United States government restricted party list, or for any use those laws prohibit. Primcast may refuse an order, end a Rental or close an account without refund where it believes these laws require it.
Primcast may suspend or end a Rental immediately and without refund when it has reason to believe the Renter is breaching these Terms.
A Host that receives a complaint or sees abuse coming from a Rental should report it to support@primcast.com with the time and the evidence it has.
Every Rental is tied to a Renter account, its payment records and the connections made to it through the Relay. Primcast keeps those records and discloses them where required by law, court order or valid legal process. Primcast does not disclose a Renter's identity to a Host, or a Host's identity to a Renter, with one exception. Where a Host gives Primcast a claim that a Renter damaged its Machine by breaching these Terms, supported by the available machine records and other evidence that reasonably show the damage, the breach, that the breach caused the damage and what it reasonably costs to put right, Primcast may give that Host the Renter's name and an address for the Renter that Primcast has checked, saying where the address comes from and when it was checked, and nothing else, so that the Host can pursue the claim (section 10). Primcast does not say that court papers can validly be served at that address. A change in a measurement does not by itself show a breach or that anyone is liable. Before it decides, Primcast sends the Renter the claim and its evidence, says who would receive the name and address and why, and gives the Renter fourteen days to answer or object, or longer where the Renter shows it needs longer; the Renter may give an address for service of its own choosing, which is then the one given. A Renter's silence is not an admission. Primcast may refuse or postpone where the claim is not adequately supported, where the information is not needed to pursue it, where there is a risk of misuse or to someone's safety, where the Renter raises a material objection, or where the law restricts it, and tells the Host the reason in brief. Primcast considers an objection made in time before it gives anything, records how it weighed it, and tells the Renter its decision and the reasons before the name and address are given, unless the law forbids telling the Renter. Where the law itself requires Primcast to give information, it follows that requirement and gives no more than it requires. Primcast does not decide whether the Renter owes the Host anything. The Host may use the name and address only to pursue that claim, must keep them secure, must not publish them or use them to contact the Renter about anything else, and must delete them when the claim is finally over: when it is settled or dropped, or when a judgment can no longer be appealed and has been paid or can no longer be enforced. Until then the Host keeps them where only those dealing with the claim can reach them, and after that only for as long as a law requires the Host to keep them. Where Primcast has no address it can rely on, it says so and gives none.
The Host bears the ordinary cost and risk of running its Machine: power, cooling, the internet connection, ordinary wear of its components, including storage written to by a Rental and continuous full load, ordinary electrical or mechanical failure, and the loss of anything the Host keeps on it.
Primcast provides no insurance for a Host's Machine, premises or connection, and does not compensate a Host for damage, wear or loss. This does not exclude Primcast's liability for its own negligence or its own breach of these Terms, within the limits of section 11. A Host should consider whether suitable insurance is available to it.
A Renter is responsible to the Host of the Machine it rents for damage it causes to that Machine by doing what section 8 forbids. A failure caused that way is damage, not ordinary failure. Heavy lawful computing, running the Machine at full load and ordinary writing to its storage are not forbidden acts, even if a part later fails; that a failure followed a Rental, or that a reading changed, does not show what caused it. The Host is an intended beneficiary of this promise and of section 12 and may enforce them against the Renter directly, although the Renter's contract for the Rental is with Primcast. The Host must show the forbidden act, that it caused the damage, and the amount. The amount is the reasonable, documented cost of repairing the physical damage, up to what the part was worth just before the damage allowing for its age and use, or that worth where repair is not reasonable. It does not include lost rent, lost profit, any other indirect loss or punitive amounts, and section 12 adds nothing to it. A Renter owes only the part of a loss that its forbidden act is shown to have caused. The Host tells Primcast of the damage within 30 days of finding it, keeps the evidence and takes reasonable steps to limit the damage; telling late reduces what the Host can recover only as far as the Renter shows that the delay harmed its ability to look into the damage, limit it, keep evidence or answer the claim, and is never by itself a loss of the claim or a sign of when the damage happened. What the Host has received and keeps for the same damage from an insurer, under a warranty or from anyone else comes off its own claim. An insurer that has paid the Host keeps whatever claim the law gives it in the Host's place, and no more than the Host had. The Host and anyone claiming through it may not recover the same loss twice, and together they recover no more than the loss this section allows. The Renter keeps every defense the law gives it, and a court decides a claim the Renter disputes: neither a reading of the Machine under section 5 nor anything Primcast says or does decides it.
Primcast is not a party to such a claim. It provides the records it holds where the law permits or requires it, and may name the Renter to the Host as section 9 provides. Primcast is not liable to the Host for what a Renter does, except to the extent that Primcast's own negligence or its own breach of these Terms caused the loss.
The marketplace, the Agent and the Relay are provided "as is" and "as available". Sections 5 and 6 of the Terms of Service apply to Hosts and Renters alike.
Primcast does not promise a Host that its Machine will be rented, or for how long, and does not promise a Renter that a Machine will stay listed or available.
Primcast's total liability to a Host, if any, shall not exceed the rent Primcast paid or owes that Host for the three (3) months before the event, or $2,000 if that is more. Its total liability to a Renter, if any, shall not exceed the amount the Renter paid for the affected Rental period. These limits do not apply to rent a Host has earned, to a refund or unused Balance owed to a Renter, or to any other amount due under these Terms, each of which is owed in full; to fraud, gross negligence or willful misconduct; to what Primcast owes under a data processing agreement, which has its own terms; or to any liability that the law does not allow to be limited. Where Primcast and a Host have signed a separate agreement that sets a different limit for that Host's Machines, that limit applies to them in place of the one above.
The Renter agrees to indemnify Primcast and the Host of the Machine it rents against claims brought by someone else, and the losses, damages and reasonable expenses that follow from them, to the extent that they are caused by the Renter's breach of these Terms or of the law in its use of a Rental, including storing or transmitting content that infringes someone else's rights or is otherwise unlawful. The Host may rely on this section directly.
The Host agrees to indemnify Primcast against claims brought by someone else, and the losses, damages and reasonable expenses that follow from them, to the extent that they are caused by the Host's breach of these Terms, by its not having the right to list the Machine, or by access to or interference with a Rental that these Terms do not allow.
Whoever asks to be indemnified tells the other promptly of the claim, lets it lead the defense with counsel the one defended can reasonably accept, and helps as far as is reasonable; where their interests conflict, the one defended may have its own counsel, whose reasonable cost is part of what is owed. Telling late matters only as far as the delay did harm. The other does not settle in a way that admits fault for the one it defends, puts an obligation on it or leaves it to pay, without its agreement. Only the reasonable costs of defending a claim this section covers are owed. No one is indemnified for the part of a loss that its own negligence or breach caused, nothing in this section takes away a right the law gives a consumer, and damage to a Host's own Machine is a matter for section 10 alone.
Primcast does not indemnify Hosts or Renters.
A Host may leave the marketplace at any time by removing its Machines; earnings accrued until then are paid at the next payout, under section 7. A Renter may end a Rental at the end of a paid period. A Rental paid from the Balance may also be ended at any time, without a refund of the period that has started.
Primcast may suspend or remove a listing, a Rental or an account that breaches these Terms, fails verification, or puts the marketplace, a Host or a Renter at risk. Sections 9 to 12 survive termination.
Section 11 of the Terms of Service governs changes to these Terms. Primcast emails Hosts and Renters, and shows a notice in the dashboard, at least 30 days before a change that reduces their rights or adds to their obligations takes effect, and the change applies to a Host or a Renter only from the later of that day and the day it accepts it: to a Host from the first payout period that begins after that, and to a Renter from the first paid period that begins after that. Registering a Machine, listing, paying or going on using a Rental does not by itself accept a change. A change never reduces earnings already accrued or alters a period already paid for.
Section 12 of the Terms of Service (disputes, arbitration, class action waiver, time limit for claims and governing law) applies to these Terms and to every Dispute between a Host or a Renter and Primcast, including Disputes about earnings, payouts, the recovery of earnings, Rentals and identity verification. A Host acting as a Host takes Disputes to court, not to arbitration. Section 12 does not govern a claim between a Host and a Renter, to which Primcast is not a party: such a claim is decided by a court that has jurisdiction over it, nothing in these Terms requires it to be brought in New York or in arbitration, and a Renter who is a consumer keeps the courts and the mandatory law of the country where they live.
Where these documents say different things about the same matter, they apply in this order: the law that cannot be set aside by agreement; for a transfer of personal data, the transfer clauses that apply to it, by their own rule of priority; the data processing agreement; for a Host established in the European Union or the European Economic Area, the supplement to these Terms, for the subjects it covers; these Terms, for the GPU marketplace, including the refund of unused Balance and of time lost to an outage; the Refund Policy, for refunds of other services; and then the Terms of Service. Nothing in this order takes away a right the law gives a consumer, a person whose personal data is processed, or a business user. Our Privacy Policy explains how we process personal data; it is not consent to processing, it does not reduce a right under data protection law or the data processing agreement, and it does not change the priority of a transfer clause.
A Host established in the European Union or the European Economic Area also receives a supplement to these Terms, shown in its dashboard, which forms part of them.
