1. What these Terms cover
“Substratal” or the “Service” means:
- the Substratal Apps platform and its API at
api.substratalapps.com, including its MCP server; - the Substratal Hub apps for web (
hub.substratalapps.com), macOS, Windows, Linux, iOS and Android; - the applications Substratal publishes that you sign in to with a Substratal account; and
- this documentation site.
By creating an account, signing in, installing a Hub app, or using the API, you agree to these Terms, the Acceptable Use Policy, and the Privacy Policy. If you use Substratal for an organization, you agree on its behalf and confirm you’re authorized to.
Additional terms apply to some uses, and take precedence for that use where they conflict with these Terms:
- registering an Application or using an API Key: the Developer and API Terms;
- installing a Hub app: the End User License Agreement;
- processing personal data on behalf of an Organization or developer: the Data Processing Addendum.
2. Eligibility
You must be at least 13 years old, or older where your country requires it (16 in some EEA countries), to create an account. Substratal isn’t directed to children under 13, and we delete accounts we learn belong to one. You must be able to form a binding contract, and not be barred from receiving services under the laws of the United States or your country.
3. Your account
- Give accurate information, keep your email address current, and keep your password and second factor secure. You’re responsible for activity under your account.
- Tell us promptly at
security@substratalapps.comif you think your account has been compromised. You can sign out of every device yourself from the Hub’s security settings. - An Organization’s administrators can invite you, manage which apps its members can use, and remove you from it. Removal ends any access that came from that Organization; it doesn’t delete your account.
- An Application’s developer, or an administrator, can turn your access to that Application on or off. Your Substratal account continues to work for everything else.
4. Plans, billing and cancellation
- Free costs nothing and needs no payment method.
- Standard is $6 per user per month, billed monthly in US dollars, plus applicable taxes. You can subscribe for yourself, or an Organization can subscribe for the members it chooses. Current prices are on Pricing.
- Payments are processed by Stripe. We never see or store your full card number. By subscribing you authorize recurring charges until you cancel.
- Cancel anytime in the billing portal. Standard continues until the end of the period you’ve paid for, then your account returns to Free. Except where the law requires otherwise, payments are non-refundable and partial periods aren’t credited.
- An Organization’s subscription is charged for the number of covered members, counted once a day, without mid-period proration.
- If a payment fails, Standard access may end at the end of the paid period. We may change prices with at least 30 days’ notice; a change applies from your next billing period after the notice.
5. Your content and data
- You keep all rights to the content and data you put into Substratal (“Your Content”), including profile details, settings, and data an application stores for you.
- You give us a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, and display Your Content only to operate, secure, and improve the Service for you and as described in the Privacy Policy. This license ends when Your Content is deleted from the Service, except for backups and records we must keep by law.
- You’re responsible for having the rights to Your Content and for its legality.
- You can export your data at any time (Hub › Account › Privacy, or
GET /users/me/export), and delete your account as described in Account and Data Deletion.
6. Acceptable use
Follow the Acceptable Use Policy. In short: no illegal activity, no abuse of other people, no attacks on the Service, no attempts to get around access controls, rate limits or billing, and no use of the Service to send spam.
7. Our intellectual property
The Service, including its software, designs, and the Substratal name and logo, belongs to Composite Code and its licensors. These Terms don’t grant you any rights to it except the limited right to use the Service under these Terms, and the licenses in the EULA and Copyright, Licenses and Trademarks. Source code that we publish under an open-source license (such as the MIT License) is governed by that license.
Feedback. If you send us ideas or suggestions, we may use them without obligation to you.
8. Third-party services and applications
Some features rely on third parties: Stripe for payments, Apple, Google and browser vendors for push notifications, and Amazon Web Services for hosting (see Sub-processors). Applications built by developers other than Composite Code are provided by those developers under their own terms and privacy policies; we aren’t responsible for them. Those developers set their own prices and take payment their own way. A Substratal subscription doesn’t include their Applications, and we don’t process their payments.
9. Changes to the Service and to these Terms
We may add, change, or remove features. We’ll give reasonable notice before removing a feature you pay for. We may update these Terms; for a material change we’ll notify you by email or in the Hub at least 30 days before it takes effect. If you keep using Substratal after a change takes effect, you accept the updated Terms. If you don’t agree, stop using the Service and cancel any subscription before then.
10. Suspension and termination
- You can stop using Substratal and delete your account at any time.
- We may suspend or terminate your account, or your access to an Application, if you materially breach these Terms or the Acceptable Use Policy, if required by law, or to prevent harm to the Service or others. Where practical, we’ll tell you why and give you a chance to fix it first.
- On termination, your right to use the Service ends. Sections 5 (license end and export), 7, and 11 through 15 survive.
11. Disclaimers
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE FULLEST EXTENT PERMITTED BY LAW, COMPOSITE CODE DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND DOESN’T WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE. Some jurisdictions don’t allow these exclusions, so some may not apply to you.
12. Limitation of liability
TO THE FULLEST EXTENT PERMITTED BY LAW:
- COMPOSITE CODE ISN’T LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL, EVEN IF ADVISED OF THEIR POSSIBILITY; AND
- COMPOSITE CODE’S TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) US $100.
These limits don’t apply to liability that can’t be limited by law, such as for fraud, gross negligence, or willful misconduct.
13. Indemnity
If you use the Service for a business or organization, you’ll defend and indemnify Composite Code against third-party claims arising from Your Content or your violation of these Terms or the law, and pay resulting damages and reasonable costs.
14. Governing law and disputes
These Terms are governed by the laws of the State of Washington, USA, without regard to conflict-of-laws rules. Any dispute will be resolved exclusively in the state or federal courts located in King County, Washington, and you and we consent to their jurisdiction. If you’re a consumer in a country whose law gives you the right to bring claims in your local courts, or under mandatory local consumer-protection law, nothing here takes that right away. Before filing a claim, please contact legal@substratalapps.com so we can try to resolve it informally within 30 days.
15. General
- Entire agreement. These Terms and the documents they reference are the whole agreement between you and us about the Service.
- Severability. If a provision is unenforceable, the rest remains in effect.
- No waiver. Not enforcing a provision isn’t a waiver of it.
- Assignment. You may not assign these Terms without our consent. We may assign them in a merger, acquisition, or sale of assets, with notice to you.
- Force majeure. Neither party is liable for delays caused by events beyond reasonable control.
- Export and sanctions. You’ll comply with US export-control and sanctions laws.
- Notices. We send notices to your account email or in the Hub. Send notices to us at
legal@substratalapps.com.
