Terms
Last updated 13 November 2026.
These terms are between you and Stu Mason, a sole trader in the United Kingdom, and cover the Power-Ups offered at powerups.stumason.dev.
Using a Power-Up
You may use a Power-Up on any Trello board you are allowed to edit. You are responsible for what you import and for having the right to put it there. A Power-Up acts with the permission you give it in Trello and makes the changes you confirm on screen; check the preview before you import.
Subscriptions
A subscription covers one Trello workspace: every board in it and every member of it. It is billed monthly in advance through Stripe and renews until cancelled. You can cancel at any time and keep the paid features until the end of the month you have paid for. If something has gone wrong and you want your last payment back, write within 14 days of that payment and it will be refunded.
If the price changes, existing subscribers will be told by email at least 30 days before it applies to them.
What is not promised
The Power-Ups depend on Trello and its API, which we do not control, and they are provided as they are. We take care to make imports safe and reversible, but you should keep your own copy of anything important. To the extent the law allows, our liability to you is limited to what you paid in the twelve months before the problem. Nothing here limits rights you have as a consumer under the law of the country you live in.
Trello
These Power-Ups are independent. They are not made, endorsed or supported by Atlassian, and your use of Trello itself is under Atlassian's own terms.
Law
These terms are governed by the law of England and Wales.
