Refund & Cancellation Policy

Last updated: 7 July 2026

This policy explains how subscriptions to the SLK Engineering Suite (the "Service") can be cancelled and when refunds are available. It applies together with our Terms of Service.

1. Free trial

New organisations may start with a free trial. You will not be charged during the trial, and you are not obligated to subscribe. If you do not subscribe before the trial ends, access to the calculation engines is simply paused — no payment is taken.

2. Cancelling your subscription

3. Refunds

We want you to be satisfied with the Service. Our refund terms:

Refunds are processed by Paddle to your original payment method and typically appear within 5–10 business days, depending on your bank or card issuer.

4. How to request a refund or cancel

Contact us at support@slk-llc.com with the email address used at purchase and, if available, your Paddle order/receipt reference. You may also request assistance directly from Paddle via the receipt they email you after purchase.

5. Statutory rights

Nothing in this policy limits any non-waivable refund or cancellation rights you may have under the consumer-protection laws that apply to you.
