Purchase terms

Who provides Seido

Seido is provided by Seido AI Ltd, company number 16704256, registered in England and Wales at 17 Meriden Close, Bromley, BR1 2UF, United Kingdom. Contact help@seido.dev or +44 7935 853732 on WhatsApp.

Seido helps you develop and use a connected knowledge base, with a visual graph, pages and conversational assistance. It is an early product. Check the available features and limits before paying; roadmap features are not included just because they are planned. AI responses can contain mistakes. Review them before relying on them, especially for consequential decisions.

Free and Pro

Free has no time limit and needs no card. It includes one knowledge base, up to 25 topics with page content, and a monthly message allowance. Free never automatically becomes a paid subscription.

Pro includes unlimited knowledge bases and developed topics, with 500 Seido messages per paid billing period. Its base price is US$30 per month before tax. For UK consumers, the price is US$36 per month including 20% VAT, before currency conversion.

Stripe Checkout shows the final amount, tax, currency and monthly recurrence before you authorise payment. Where a local-currency option is offered, review that option's amount and recurring terms. Signing in or joining the waitlist does not authorise a charge.

Payment and product support

New Pro purchases use Stripe Managed Payments. Sold through Link, LLC is the merchant of record handling payment and covered transaction taxes; Checkout identifies it and provides the payment terms. Seido AI Ltd remains responsible for Seido and product support.

Keep your purchase confirmation and these terms for your records. For payment help, use the Stripe order-management link in your confirmation. For the product, or if you cannot reach billing controls, contact help@seido.dev. Our privacy policy explains data processing.

Monthly renewal and cancellation

Pro renews monthly and charges your agreed payment method until you cancel renewal. Stop renewal through your account's Billing controls before the next payment. Check the cancellation confirmation for the date Pro ends.

Unless a refund or another valid termination changes this, Pro continues until the end of the period you paid for. You then return to Free if your account fits its limits. Otherwise, your knowledge stays readable while you choose what to remove or whether to subscribe again.

Closing your Seido account also ends its subscription; account access ends as part of closure. Closing an account is not a request for a refund. To stop renewal and keep your account, use Billing instead.

Refunds and your rights

We do not offer voluntary change-of-mind refunds or a money-back guarantee. Stopping renewal or deciding not to use Seido does not, by itself, refund a paid period.

This does not remove refunds or other remedies required by law, or Stripe Managed Payments' authority to issue a refund. If something you paid for is not provided as agreed, contact us. You do not have to accept future development instead of a remedy you are legally entitled to.

Choosing business or personal use for tax classification does not itself decide whether you are legally a consumer or waive any consumer right. Mandatory rights in your country continue to apply.

UK consumers: cancelling a new purchase

You can cancel a new paid contract without giving a reason until the end of 14 days after the day the contract is made. This is different from stopping future renewal. Tell us clearly by email or post using the contact details above. You can use the form below, but do not have to.

If you expressly request that the service starts during that period, a proportionate charge for service already provided is payable only where the law permits it and the required information and request were given. Using Seido alone does not waive your cancellation right.

A refund legally due for this cancellation will be made without undue delay, no later than 14 days after you tell us, using the original payment method unless you expressly agree otherwise. No refund fee is deducted.
