Terms of service

The agreement between Base Captain, LLC and the business that uses Base Captain. Base Captain is for businesses only: by signing up or creating a base you accept these terms for a business, and consumer law, such as the right to withdraw within fourteen days, does not apply.

Last updated 12 November 2026

The parties

Base Captain, LLC, a Delaware limited liability company ("we"; its address is on Legal), and the business that signs up or creates a base ("you"). The data processing agreement and the acceptable use policy are part of these terms.

The service

What Base Captain is.: A service for running a business: you create bases, change them by asking the assistant, and have agents and workflows do part of the work. The docs on this site describe what it does.
It changes.: We improve Base Captain all the time, and the changelog says what changed.

Users

Your sign-in is yours.: Keep your password and your second factor to yourself, and tell us at once if someone else may have used them.
Your users.: The base's owners and builders decide who belongs to it and what each role may see and do. You answer for what your users, your agents and your API tokens do in your bases.
Accurate details.: Give us a name and an email address that reach you, and keep them current.

The plan and payment

The Free plan.: A base may be on the Free plan or on the Pro plan. The Free plan costs nothing and lasts 30 days from the moment the base is made. The number of free bases a person may have, and that one card may unlock, is limited for fair use. Without a payment method, a free base works only with its own users: mail to other addresses, public forms and links, outside calls, webhooks, incoming mail and payments stay closed, as the docs describe. An owner may add a payment method, which Stripe checks with no charge; the bank can show a small amount for a short time. The Free plan has 250 MB of storage, 1 GB with a payment method.
When the Free plan ends.: At the end of the 30 days, the base becomes read-only: every user can still sign in, read and export, but nothing can be changed and nothing runs, such as the assistant, agents, workflows and mail. 30 days later, its data and its files are deleted. The base stays, with its owners, its billing details and its invoices. An owner who upgrades to Pro before the deletion opens the base again at once. The owners get emails before the end and before the deletion.
Monthly charges.: The Pro plan is paid on the 1st of each month (UTC), in advance, by the card on file, through Stripe. The first month is charged for the time left in it, to the second, from the start of the plan to the next 1st (00:00 UTC); when that part is less than 2 (in dollars or euros), nothing is charged until the next 1st. Prices are in euros for a business in a European country and in US dollars for any other.
Taxes.: Prices do not include taxes, and we add none to them. You pay the taxes that the law of your country puts on your purchase: a business in the EU pays the VAT itself, in its own country, under the reverse charge, and its invoices say so. If a law requires us to collect a tax on your purchase, we add it to the price and show it on the invoice. You keep the billing details correct in the base’s Settings, Plan.
Storage.: Each plan has a storage limit, which the base’s Settings, Plan and its Storage page show. The storage counts what the base keeps: its records, its files and its chat. The count of a base starts at zero and grows as the base keeps more. When the storage is full, new records and uploads are refused until an owner adds storage or the base deletes data, as the docs describe.
Fair use.: Each plan includes the AI, the mails to outside addresses and the invitations for the normal use of a base, the Free plan less than the Pro plan. Limits on them protect the service for all customers. When a base reaches a limit, that feature pauses until the period of the limit ends, and Base Captain says when it works again. If your base needs more, contact us.
Added storage.: On a paid plan an owner may add storage, 1 to 10 GB at once and at most 10 GB in a calendar month unless we raise it for the base. Added storage is there at once and is free until the end of that month; from the next 1st it is charged each month with the plan. An owner may remove added storage when the base’s data fits under the lower limit: the limit falls at once, and the price on the next 1st.
Cancelling.: An owner of the base may cancel at any time. A paid plan cancelled runs to the end of the paid month and is not renewed.
No refunds.: Charges are final: nothing is refunded, for a part of a month or for a month unused.
When the Pro plan stops.: When the Pro plan stops, the base does not move to the Free plan: it becomes read-only, and 30 days later its data is deleted, as when the Free plan ends. This happens at once when the first charge fails, at the end of the paid month when an owner cancels, and seven days after a monthly payment fails, while Stripe tries the card again. A payment before the deletion opens the base again.

Acceptable use

You and your users use Base Captain only as the acceptable use policy allows. It restricts what may be kept or done in a base; we act on it through reports of abuse, each read by a person, with no automated moderation.

Your data

Your data stays yours.: Everything you put in your bases belongs to you. You give us only the right to store and process it to run Base Captain for you, as the data processing agreement sets out.
Export at any time.: Any list exports as a spreadsheet, and all of a base's data as one zip, whenever you like, at no charge.
No training.: Nothing you put in Base Captain is used to train AI models.

Switching and leaving

Notice.: You may ask to move your data to another provider or to your own systems, or to have it deleted, at any time. The switch starts at the end of the notice you choose, which is never more than two months.
Thirty days to take it out.: From then, you have a transition of thirty days in which the service keeps running and you export everything, with the exports described on the data page.
Then thirty more, then deletion.: After the transition you have at least thirty more days to retrieve your data. Once they have passed, all the data of your bases is deleted.
No charges.: Switching, exporting and leaving cost nothing.

What the exports hold, their formats and what they leave out are on Your data and leaving. This follows Chapter VI of the EU Data Act.

AI output

Check what the AI does.: The assistant and the agents can be wrong. What they write, propose or change is yours to check before you rely on it, and the decisions you take with it are yours.
Large changes wait for you.: Deletes, bulk edits and changes to a base's structure come as a card a person approves, and every change is recorded and can be undone.

Availability

Availability.: We work to keep Base Captain running, but promise no level of availability until we publish one.

Suspension and termination

You may leave at any time.: By switching as above, or by deleting your bases yourself (the data page says how).
Suspension.: We may suspend a base or a user that breaks the law, the acceptable use policy or these terms, or puts others at risk. We tell you why, and how to contest it, unless the law forbids it; we suspend only what we need to, and only for as long as we need to.
Termination.: We may end this agreement for a serious or repeated breach. Otherwise we end it only with notice long enough for you to export your data and switch. If we shut the service down, we give at least ninety days’ notice, and the export works until the last day.

Liability, changes and law

Liability.: As far as the law allows, neither side answers for indirect loss or lost profit, and our total liability is limited to what you paid us in the twelve months before the claim. Nothing here limits liability the law does not allow to be limited, such as for harm caused on purpose or by gross negligence.
Changes to these terms.: We publish changes here with a new date, and tell customers by email before a change that matters applies.
