Refund Policy
Last updated: June 21, 2026
KaiPCB is a product of NotchBio (“NotchBio”, “we”, “us”).
1. Overview
This Refund Policy explains how subscription refunds work for KaiPCB, the AI-assisted PCB design service operated by NotchBio. Payments for KaiPCB subscriptions are processed by Paddle, our payment processor and merchant of record. Paddle’s own buyer terms (available at paddle.com/legal/buyer-terms) also apply to your purchase.
2. Try before you pay
KaiPCB has a Free plan so you can evaluate the product — design and generate boards, view schematics, PCB, and 3D outputs, and export files — before subscribing. We encourage you to use it to confirm KaiPCB fits your needs before upgrading.
3. 14-day refund window
If you upgrade to a paid plan (Pro or Ultra) and are not satisfied, you may request a full refund of your most recent payment within 14 days of that charge. No conditions apply — simply contact us within the window and we will process the refund.
4. Cancellations
You can cancel or downgrade at any time from the Billing tab in Account settings. Cancellations and downgrades take effect at the end of your current billing period — you keep your current plan and access until then, and you are not charged again. Upgrades take effect immediately.
5. How to request a refund
Open the in-app Support tab (Account settings → Support) and send us a message with your account email. We aim to respond within a few business days. Approved refunds are issued to your original payment method through Paddle; the time to appear on your statement depends on your bank.
6. Changes
We may update this Refund Policy from time to time; the “Last updated” date above reflects the current version. This policy is in addition to any rights you have under applicable consumer law.
