Terms of Service

NaN is operated by Helmcode S.L. (NIF B44788511), Avenida Quinto Centenario 27, Santiago del Teide, Spain. Contact: info@helmcode.com. By accessing nan.builders and the member platform you accept these terms. If you disagree, do not use the service.

The community

NaN is a paid community of builders sharing dedicated GPUs to run open models. Anyone can create a free account; the community, inference, workspaces and the rest of the products only switch on with a paid plan. Every inference member gets a personal, non-transferable API key.

Acceptable use

• Do not share, resell or transfer your API key.
• Do not abuse the shared cluster or attempt to exceed the published limits.
• NaN is inference, not training: use the cluster to run models, not to fine-tune them.

Membership and payments

Membership is a monthly subscription with taxes included, month to month, with no commitment. You can cancel anytime; access runs until the end of the paid period.

Workspace backups. Workspaces have no backups unless the workspace backup add-on is active. With the add-on, a snapshot of the workspace disk is taken once a day and kept for 7 days. Snapshots are crash-consistent: restoring one is equivalent to the machine losing power at the moment the snapshot was taken, so data the workspace had not yet written to disk is not included and running databases recover as after a power cut. Restoring a snapshot brings back everything that was on the disk at that time, including any access you configured yourself inside the machine (for example keys in ~/.ssh/authorized_keys or SSH server settings you added). A restore does not change the SSH keys you manage for the workspace in the member platform: they are not stored on the workspace disk, so after a restore the keys that can log in are the ones in that list at that moment. Keys added inside the machine have no effect on logins through the NaN SSH gateway. You can restore up to 3 times per workspace in any 24 hours; there are no on-demand backups. Snapshots can only be restored while the add-on is active: during a grace period you must attach the workspace to an active slot (or renew the membership, for a free workspace) and turn the add-on on again, which is billed again. Enabling the add-on charges the first payment right away (prorated to the renewal date when it is added to a slot subscription); turning it off removes it immediately with no refund for the current month. Turning the add-on off or deleting the workspace deletes all its snapshots permanently. If the workspace's slot ends, or a free workspace loses the membership benefit, the add-on stops being billed. When billing ends, no new snapshots are taken and existing snapshots are kept until the workspace is deleted at the end of its grace period. If the workspace is back in good standing but the add-on is not turned on again within 14 days, the add-on ends and its snapshots are deleted. Kept snapshots are not pruned while the add-on is off. After the add-on is turned on again, only snapshots from the last 7 days can be restored; older kept snapshots are deleted with the next daily backup. Deleted snapshots cannot be recovered.

Token packs. A token pack is a one-time purchase of tokens for a single model; it is not a subscription and does not renew. You can buy token packs with or without a membership. Packs are sold in four sizes (500M, 1,000M, 5,000M and 15,000M tokens) for the models offered in the portal at the time of purchase; a pack only works with the model it was bought for, and input and output tokens count alike. Members with an active Inference, Premium or Gentle subscription pay 5% less on every pack. Purchased tokens are valid for 6 months from your last purchase for that model: each new purchase for the same model, manual or automatic, adds its tokens and extends the whole remaining balance of that model to 6 months from that purchase. Expired tokens are lost. With an active Inference, Premium or Gentle subscription, pack tokens are only used once your monthly or period allowance for that model is used up; the allowance keeps resetting as usual and never consumes or resets the pack balance. Without one (including a Community membership), every token you use is drawn from your pack balance for that model, and requests to that model stop when the balance reaches zero. Token packs give access to the inference API for the models you hold a balance for; they do not include Discord, Spaces, image generation, the MCP endpoint or any other plan feature. A balance bought under an earlier offer for a model that is no longer sold as a pack stays usable until it runs out or expires. A balance for a premium model bought under an earlier offer can only be used while you have an active Premium subscription, as long as that model is not sold as a pack. While your membership payment is in its grace period the balance is paused and the expiry date keeps running. Prices are in euros. If your billing account is already set to US dollars, you are charged in dollars: the euro price times 1.08, rounded up to the whole dollar, before the subscriber discount. Prices are shown before purchase and include taxes; no VAT is added at checkout.

Token packs are non-refundable. Under EU consumer law, digital content is normally subject to a right of withdrawal: token packs are supplied immediately at your express request, and you acknowledge that you lose your right of withdrawal once they are supplied. A refund required by law, or a chargeback or payment dispute, removes the tokens credited by that purchase from your balance. To protect members and cardholders, we limit how many packs can be bought per day per account and per card, and we may ask your bank to authenticate the payment. A payment that exceeds those limits, that does not match the price shown at checkout, or that completes after the checkout expired is refunded in full and no tokens are added. Token packs do not lift any other limit: concurrency, rate limits and fair use still apply.

Holds and bans. If a token pack payment, or any other payment on your account, is disputed or flagged as possible fraud by the card issuer, or if a card is used on more accounts than we allow, we may put token packs on hold for your account: all pack balances are frozen, automatic recharges are turned off and, if you have no active Inference, Premium or Gentle subscription, your API key is revoked until the hold is resolved. A dispute decided in your favour restores the tokens and closes the hold, and we may close a hold after review; automatic recharge stays off until you turn it on again. If your account is banned for a breach of these terms, your API key is revoked, automatic recharges are turned off and any remaining pack balance is forfeited without refund.

Automatic recharge. Where offered, you can turn on automatic recharge for each model: every time your balance for that model is worth less than the threshold you set (valued at your current price for that model's 1,000M pack), we charge your saved card the price of the pack you chose. It is off by default; turning it on requires your explicit acceptance of those charges, which we record with its date, and it charges nothing by itself. Automatic recharges are limited by a monthly cap you set (10 euros by default) and to 3 automatic recharges per 24 hours across all models. If a charge is declined, we retry it up to three more times, after 1 hour, 24 hours and 72 hours; if your bank asks you to confirm a payment, we ask you to confirm it within 72 hours instead of retrying. After the last failed attempt, an unconfirmed payment or the removal of the card, automatic recharge for that model is turned off. You can turn it off at any time; a charge already sent to your bank still completes. Automatic recharge is available in euros only. Each automatic recharge is a token pack purchase under these terms, including the loss of the right of withdrawal and the non-refundable nature of packs.

Prepaid minutes for ephemeral runs. Prepaid minutes are a one-time purchase of balance for ephemeral runs, by card, in euros; they are not a subscription and do not renew, except through automatic recharges you turn on yourself. The balance is used only after the free minutes of your plan and before any per-minute billing on a membership. It is valid for 6 months from your last purchase or recharge: each purchase or recharge extends the whole balance to 6 months from then. Expired balance is lost. Prepaid minutes are supplied immediately at your express request, and you acknowledge that you lose your right of withdrawal once they are added to your balance; the same applies to each automatic recharge. Prepaid minutes are non-refundable. A refund required by law, or a chargeback or payment dispute, removes the balance credited by that payment that is still unused and turns auto-recharge off; a payment dispute may also suspend ephemeral runs on the account until it is resolved. If a run fails because of a fault on our side, we may credit your balance instead. While your membership payment is overdue or your account is banned, the balance is frozen: it cannot be used for new runs and cannot be topped up, auto-recharge is paused and the expiry date keeps running. The balance is lost when your account is deleted. By turning auto-recharge on you authorise us to charge the card you choose, without you being present, the recharge amount you set each time a run leaves your balance below your threshold or needs more than you have; turning it on charges nothing by itself. Automatic recharges count towards your monthly spend cap for ephemeral runs, and you can turn them off at any time. Prices are shown before purchase and include taxes; no VAT is added at checkout.

Workspace acceptable use

This section applies from October 6, 2026. Workspaces are personal machines for your own development work. You are responsible for everything that runs on your workspace and for all the traffic it sends, including what agents run on your behalf. You may not use a workspace to:

• mine cryptocurrency;
• scan, probe or attack third-party systems, other members' workspaces or our own infrastructure, or try to gain unauthorized access to them;
• launch or take part in denial-of-service (DDoS) attacks;
• send spam, run phishing, or host or distribute malware;
• run open proxies, offer VPN services to others, or run Tor exit or relay nodes;
• carry out credential stuffing, brute-force logins or other automated attacks on accounts;
• host, store or distribute illegal content;
• resell, sublet or share the workspace's compute or network access with third parties.

Reverse tunnels are allowed only to give you access to your own workspace and for your own development use, and never to expose any of the services or activities listed above. Outgoing email (SMTP) is blocked and network limits apply to every workspace; trying to get around them is a breach of this policy.

If we detect abuse or receive a report of it, we may suspend or delete the workspace, its backups and the slots involved without prior notice, and suspend your membership. A suspension or deletion for abuse gives no right to a refund. We cooperate with abuse reports from third parties and with the competent authorities, and we share the information the law requires.

When a workspace is deleted, whether by you, at the end of its grace period, or by us, its disk and all its backups are deleted permanently and cannot be recovered. Keep your own copy of anything you cannot afford to lose.
