Terms and Conditions

Last updated: 2026-05-18

These terms are the agreement between you and Sweatkraft AS (the company behind SweatStack) for using SweatStack. We've tried to keep them short and plain. If anything is unclear, email [email protected].

Part A applies to everyone with a SweatStack account, free or paid. Part B additionally applies if you build on the SweatStack API.

What SweatStack provides

  • A web application for sports data analysis and management.
  • APIs, SDKs, and AI tooling for building on top of your data.
  • Integrations with wearable platforms and devices.
  • Any other tools or services included in your plan.

Part A — for everyone

Account eligibility

You need to be at least 16 years old to use SweatStack. By creating an account you confirm you meet that bar and that the information you give us is accurate.

How you can use SweatStack

You can:

  • Access, analyze, manage, and export your sports data.
  • Share data with other users, organizations, and third-party applications you authorize.
  • Build applications using our API (see Part B).
  • Publish applications that provide genuine value in our app directory.

We ask that you:

  • Only access data you have permission to view.
  • Use the service responsibly and don't try to disrupt it for others.
  • Don't use SweatStack for anything illegal.
  • Use the API within published rate limits; if you need more, let us know.

If you violate these, we may suspend or terminate your account, or remove apps from the directory. Where possible we'll tell you first.

Your data

You stay in control of your data:

  • Choose what to share, with whom, and through which apps.
  • Disconnect apps, export your data, or delete your account whenever you want.
  • See our Privacy Policy for what we collect and why.

Not medical advice

SweatStack is a tool for training insight, not a medical device. The data, analyses, and recommendations you see — whether produced by SweatStack or by third-party apps built on SweatStack — are not medical, diagnostic, or clinical advice. Don't rely on them to diagnose, treat, or make decisions about a medical condition. If you have a health question, talk to a qualified professional.

Free and paid tiers

These terms apply to both free and paid use. If you have a paid plan, billing is handled by Stripe under the plan you selected. You can cancel anytime; cancellation stops future billing but does not refund the current period unless we agree otherwise or local consumer law requires it.

Ending your account

You can delete your account anytime from the app. We'll remove your data on the timeline described in the Privacy Policy. We may also terminate or suspend your account if you materially violate these terms or if continuing to provide service to you would expose us to legal risk; in non-urgent cases we'll give you reasonable notice and a chance to export your data first.

Service quality

We aim to keep SweatStack reliable and to communicate clearly when things break. The service is provided "as-is" without warranties beyond what local law requires. Some things — like the wearable platforms we depend on — are outside our control.

Liability

To the maximum extent permitted by law, our liability for any claim arising out of these terms or your use of SweatStack is limited to the fees you paid us in the 12 months before the claim. We're not liable for indirect, incidental, or consequential damages.

Nothing in this section limits liability that can't be excluded under applicable law, including mandatory consumer protections in your country of residence.

Changes to these terms

We may update these terms when the service changes or when we need to. For material changes, we'll notify account holders by email or in-app at least 30 days before the change takes effect, so you have time to review and, if you disagree, close your account.

  • Governed by Norwegian law.
  • Disputes resolved through good-faith negotiation first, then the courts of Norway. If you are a consumer, mandatory consumer protections of your country of residence still apply, and you may also bring claims in your local courts.
  • You retain ownership of your data; we own the platform and its intellectual property.

Part B — additionally for developers

This part applies if you create a SweatStack application, generate an API key, or call the SweatStack API. By doing any of these you accept it on behalf of yourself or the legal entity you represent. Where these terms refer to "you" in Part B, they mean the developer of the app.

Your role and responsibilities for user data

When an end user authorizes your app, you receive a copy of the data they grant access to. From that moment, you are an independent controller of that data under GDPR (and an equivalent role under other applicable laws). That means:

  • You need your own privacy policy that clearly tells your users what your app does with their data.
  • You handle data subject requests (access, correction, deletion, etc.) within your product.
  • You comply with applicable data protection law independently, on your side.

For data you store back into SweatStack through our app-metadata feature (or any other developer-controlled storage we offer), SweatStack acts as your processor. The terms for that are in our Data Processing Agreement, which applies automatically when you register an application.

Scopes and purpose

  • Request only the scopes your app genuinely needs.
  • Use the data only for the purposes you disclosed to the user.
  • Don't sell user data, don't use it to train ML models without explicit user consent, and don't enrich or combine it with other datasets in ways the user wouldn't reasonably expect.

Security

  • Protect your client_secret and any tokens you receive. Treat them as production credentials.
  • Use TLS for all transit, and reasonable security practices on your side.
  • If you discover a breach affecting SweatStack-sourced data, tell us at [email protected] without undue delay, and in any case within 72 hours of becoming aware. We may need that to meet our own obligations.

Deletion when users revoke

If a user revokes your app's access, or deletes their SweatStack account, delete the data you hold about them within 30 days. Routine backup retention is fine as long as deleted data isn't restored into production.

No re-sharing

Don't pass SweatStack-sourced data to further third parties unless you have a lawful basis and have bound them to equivalent obligations.

Attribution

Some data sources require attribution. Garmin, for example, requires attribution when displaying data from their devices, following their brand guidelines. You can identify the source from the device information in the activity data. We'll let you know about new attribution requirements as integrations evolve.

App directory

To be listed in our app directory, your app needs to provide genuine value to users and respect these terms. We may remove apps that don't — for example, apps that mislead users, request excessive scopes, ignore security obligations, or harm the SweatStack ecosystem. For non-urgent issues we'll tell you first and give you a chance to fix things. For security or abuse issues we may act immediately.

Rate limits and fair use

Use the API within our published rate limits. If you have a legitimate need for higher volume, email us and we'll work something out.

API stability

We give at least 12 months notice before breaking changes to the API. A breaking change is one that would cause a working integration to break or silently misbehave: removal of an endpoint, removal or rename of a field, or a change in the semantics of an existing field. Additive changes (new endpoints, new optional fields) are not breaking and may ship at any time.

Endpoints not covered by this notice period are explicitly labelled "beta" or "experimental" in both the developer documentation and the interactive API reference. They may change or be removed with shorter notice.

App-metadata

If you use our app-metadata feature to store data alongside a user's SweatStack account, you remain in control of what you store. Don't put data in there that the user wouldn't expect you to store on their behalf. See the DPA for the processor terms that apply.

License and IP

We grant you a non-exclusive, revocable, royalty-free license to use the SweatStack SDKs, CLI, AI skills, and similar tooling for the purpose of building applications on SweatStack. We don't claim any IP in the apps you build. SweatStack's name, logo, and brand belong to us — see the SweatStack Connect brand guidelines for what's okay.

Liability and indemnity

Each party is responsible for its own product. To the extent permitted by law, you'll indemnify Sweatkraft AS against third-party claims arising from your app — for example, claims by your users about what your app did with their data — except where the claim is caused by SweatStack.
