Terms of Service

SMS verification messages

Pure Reason Inc., operator of Kylon, sends one type of text message: a one-time code used to verify that you control the phone number you entered. We do not send marketing or promotional text messages.

• Message frequency: one message per verification request you make, so frequency varies.
• Message and data rates may apply.
• Reply STOP to unsubscribe. Phone verification cannot be completed after you opt out.
• Reply HELP for help, or email hello@purereason.work.

Consent is separate and optional. It is collected through its own control, unchecked by default, at the point where you enter a phone number, and is never bundled with account creation or acceptance of these Terms and our Privacy Policy, both linked beside that control. You can withdraw consent at any time by replying STOP.

Abuse, suspension, and credits

If we identify abuse of the Service, we may suspend or permanently close the accounts and workspaces involved, and we may revoke the trial, promotional, and referral credits held in them. Where the abuse is ongoing, or where advance notice would allow it to continue, we may act without prior notice.

Trial, promotional, and referral credits are granted at our discretion. They have no cash value, cannot be exchanged for money, and are not refundable when they are revoked under this section. Credits you have paid for are not revoked for other forms of abuse.

Payment fraud is treated separately. If a purchase is made with a stolen or otherwise unauthorized payment method, or through any other fraudulent or deceptive payment, we may close the accounts and workspaces involved and revoke the credits from that purchase together with any other credits they hold.

We make these decisions reasonably and on the evidence available to us. If you believe we have got it wrong, write to hello@purereason.work and we will review the decision.

Payments, cancellation, and refunds

Renewal and cancellation. Paid plans renew automatically at the start of each billing period until cancelled. You can cancel at any time in your workspace billing settings. Cancelling stops the next renewal; your plan stays active until the end of the period you have paid for.

Free trial. If you cancel before your trial ends, you are not charged. When the trial ends, your subscription starts and the first payment is charged.

Payments are non-refundable. Except as stated in these Terms or required by law, all payments are non-refundable once charged. This includes partially used billing periods, plan downgrades, unused subscription credits, and purchased credit packs. We do not give prorated refunds when you cancel or downgrade mid-period. Credits have no cash value. We may, at our discretion, offer a refund or credit in an individual case; doing so does not oblige us to do the same in other cases.

Your rights under local law. Nothing in these Terms limits any right to cancel or to receive a refund that the law where you live gives you and that cannot be waived by contract.

Business purchases. Statutory withdrawal rights for consumers do not apply to plans bought for business purposes. If you have a separate order form with us, its payment terms prevail.

How refunds work. Refunds go to the original payment method. A refund ends access to the plan for the refunded period and removes the credits that came with that payment.

Payment disputes. While a chargeback or payment dispute is open, we will not process a refund for the same payment, and we may suspend the workspace until it is resolved.

Model training on Pro and Ultra plans

If your workspace is on a Pro or Ultra plan, we do not use the content submitted to it to train or fine-tune AI models, whether our own or a third party’s. When an agent that Kylon runs processes that content, we send it only to AI providers whose terms prohibit them from training on it. This commitment covers content submitted while the workspace is on a Pro or Ultra plan.

Agents you bring. The commitment above does not extend to agents that you or members of your workspace bring into Kylon and that run outside our infrastructure, such as Claude Code or Codex. Content those agents can access is processed in the environment where they run and under the terms of the AI services they use. You decide what those agents can access, and you are responsible for that access and for how those environments and services handle the content.
