Terms of Service
Challenge Studio by Smartstack Platforms LLC · Effective 16 September 2026
The agreement for using Challenge Studio: what you may do with it, what we owe you, who owns what, and how either of us can end it.
The short version: it is free during beta, you own your challenges and your participants own what they submit, we take no cut of anything you charge, and you can export your data and leave at any time.
1.The agreement
These terms are between you and Smartstack Platforms LLC, and they govern your use of Challenge Studio. By creating an account you accept them. If you do not, do not create one.
If you accept these terms for an organisation, you are confirming you have authority to bind it, and “you” means that organisation.
2.What the service is
Challenge Studio lets you build multi-day challenges, publish a registration page, run the challenge, and see how it went. A workspace holds your challenges, your team and your branding. A participant is someone who registers for a challenge you run.
Challenge Studio is currently in beta. It works, it is in active development, and features may change. We will not remove something you depend on without telling you.
3.Your account
- You must be 13 or older, and old enough to enter a contract where you live.
- Give us an email address you can actually receive mail at — we use it for account recovery and for anything important.
- Keep your password to yourself. Anything done with your account is treated as done by you.
- Tell us promptly if you think someone else has got in.
- One person per account. Team members get their own accounts and their own roles, which is also how you keep control of who can see what.
4.What it costs
Nothing, at present. Challenge Studio is free while it is in beta. There is no billing in the product, no card on file, and no trial that quietly ends.
The plans shown on our pricing page describe what pricing is expected to look like. They are not in force, and the limits listed there are not currently applied to your account.
When pricing does arrive: we will email you first, you will keep everything you have built, and you will not find a paywall placed in front of your own challenges. If you decide not to pay, you will be able to export your participants and their progress.
5.Payments between you and your participants
If you charge for a challenge, that transaction is between you and your participant. Challenge Studio does not process payments and takes no share of what you charge — a paid challenge simply checks an entitlement you have granted through your own checkout.
Which means the obligations that come with taking money are yours: tax, refunds, receipts, chargebacks, consumer rights and delivering what you promised. We are not a party to it and cannot resolve a dispute about it.
6.Who owns what
You own your content. Your challenges, the material you put in them, your branding, and your participant records remain yours. We claim no ownership.
You grant us only the licence we need to run the service: to store your content, show it to the participants and team members you have given access, and back it up. Nothing broader, and it ends when you delete the content or your account.
Participants own what they submit. As the creator you may read it, review it and report on it inside your workspace. You may not publish it elsewhere, sell it, or use it in marketing without that person’s permission — and where a submission was marked private, treat it as written for you alone.
We own the software. Challenge Studio itself, its code, design and name stay ours.
7.What you may not do
Do not use Challenge Studio to:
- break the law, or help anyone else to;
- publish content that is unlawful, harassing, hateful, or sexual content involving minors;
- infringe someone else’s copyright, trademark or privacy;
- send spam, or register people who did not ask to be registered;
- mislead participants about what your challenge is or who is running it;
- impersonate another person or organisation, including us;
- attempt to reach another workspace’s data, probe for vulnerabilities without permission, or work around a rate limit or permission check;
- scrape the service, or resell it as your own product.
Security research is welcome — write to legal@mychallengestudio.com and tell us what you found before telling anyone else.
8.Your responsibilities to your participants
When you run a challenge you decide what happens to the personal information your participants give you, and we handle it on your instructions. That makes some things yours to get right:
- having a lawful basis to contact the people you register;
- telling them what you will do with what they submit;
- honouring their requests to be removed, and passing them to us where we need to act;
- not exporting their submissions or details for a purpose they would not expect;
- whatever consent your own jurisdiction requires if your participants are children.
Our own handling of that data is described in the Privacy Policy.
9.Availability
We work to keep Challenge Studio available and will give notice of planned maintenance where we can. During beta we do not offer an uptime guarantee or a service credit, and we would rather say that than promise a number we have not yet earned the right to promise.
Practical advice, meant sincerely: if a challenge matters, export your participants before it starts. The export is free and always available.
10.Suspension and termination
You can leave whenever you like. Ask us to close your account and we will delete it and its workspaces. Export anything you want to keep first.
We may suspend or close an account that breaks the acceptable-use section above, or where we are legally required to. Except where the breach is serious or unlawful, we will tell you what the problem is and give you a chance to fix it before acting.
If we ever discontinue Challenge Studio, we will give at least 30 days’ notice and keep the export working throughout.
11.Disclaimers
Challenge Studio is provided as it is. To the extent the law allows, we make no warranty that it will be uninterrupted, error-free, or fit for a particular purpose.
We do not promise your challenge will succeed. How many people register, how many finish, and what they achieve depend on your challenge and your audience, not on us.
12.Limitation of liability
To the extent the law allows, neither party is liable for indirect or consequential loss — lost profit, lost revenue, lost data or lost goodwill.
Our total liability to you for any claim is limited to the greater of the amount you paid us in the twelve months before it arose, or US$100. While Challenge Studio is free, that means US$100.
Nothing here excludes liability that cannot lawfully be excluded, including for death or personal injury caused by negligence, or for fraud.
13.Changes to these terms
We may update these terms as the product develops. The effective date at the top will change, and for anything significant — pricing, your rights, or how we may use your content — we will email you at least 30 days before it takes effect. Continuing to use Challenge Studio after that date means you accept the new terms; if you would rather not, close your account and take your data with you.
14.Governing law
These terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws rules. Where a dispute must go to court, it goes to the courts of that jurisdiction — though we would much rather you emailed us first and gave us the chance to put it right.
