Terms of use

Draft for review. This page isn’t in effect yet. Highlighted gaps still need details, and it should be checked by a qualified adviser before Pro opens.

These terms cover your use of StackKinetic at stackkinetic.com, including free accounts and Pro subscriptions. By using the site you agree to them. If you don’t agree, please don’t use the site.

1. Who we are

StackKinetic is run by StackKinetic, based in the Netherlands ([postal address]; KvK [KvK number]; VAT [VAT number]). You can reach us at [contact email]. “We” and “us” in these terms means the operator.

2. Using the site

• The core explainers are free to watch in full. You don’t need an account to watch them.
• You may watch, share links to and talk about any explainer. Please don’t copy, scrape, re-host or resell the diagrams, captions or data, and don’t try to get around the protections on the diagrams or the sign-in.
• Don’t use the site in a way that harms it or other people, for example by overloading it with automated requests.

3. Your account

• An account is for one person. Use an email address you control and keep your password to yourself.
• You’re responsible for what happens under your account. Tell us straight away if you think someone else is using it.
• You can ask us to delete your account at any time (see the privacy policy).
• We may suspend or close an account that breaks these terms, for example by sharing Pro access or redistributing Pro content. Where we can, we’ll tell you why first.

4. Pro subscriptions

• Pro costs €8 a month or €80 a year. Prices include VAT where it applies. The price you pay is shown before you confirm.
• Payments are handled by our payment provider, Stripe. We never see or store your full card details.
• Your subscription renews automatically at the end of each billing period until you cancel. You can cancel at any time from your account. Pro stays active until the end of the period you’ve paid for, and you won’t be charged again.
• If a payment fails, we’ll try again for a short time. Pro may pause until the payment goes through.
• If we change the price, we’ll email you at least 30 days before it applies to your next renewal. You can cancel before then.
• Refunds are covered by the refund policy.
• What Pro includes is described on the Pro page. Features marked “coming soon” aren’t part of the subscription until they launch. We add and update explainers over time and may retire one that becomes outdated, but we won’t remove a feature you’re paying for without telling you first.

5. Your licence for Pro content

While your subscription is active, you may watch the Pro explainers and download videos of them. You may use the videos you download:

• in your own presentations, talks, lessons, courses and internal training;
• in your own social posts, articles and documentation;
• for as long as you like, including after your subscription ends.

You may not resell or sublicense the videos, offer them as a library or download, remove or hide the watermark or licence details, or share your account or Pro access with others. Every Pro diagram and video carries your masked email address and a licence ID, so a copy can be traced back to the account it came from.

6. Who owns what

The explainers, diagrams, captions, data, design and the StackKinetic name belong to us. AWS, Azure, Google Cloud and other product names are trademarks of their owners. StackKinetic is independent and not affiliated with them.

7. Accuracy

The explainers simplify real systems so they’re easier to learn. We work to keep them accurate, but they are educational material, not advice for your own systems. Check the provider’s documentation before relying on a design in production.

8. Liability

We provide the site with reasonable care and skill. As far as the law allows, we aren’t liable for indirect or consequential losses, and our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that can’t be limited by law, or your rights as a consumer.

9. Changes to these terms

We may update these terms as the site changes. We’ll show the date of the latest version at the top of this page and email Pro members about important changes before they apply.

10. Law and disputes

These terms are governed by the law of the Netherlands. If you’re a consumer, you also keep the protections of the law of the country you live in, and you can bring a claim in your local courts. Please contact us first; most problems can be sorted out by email.
