Terms of Service

The rules that govern your use of pseudo-lang.com and the hosted services we run from it. The open-source Pseudo project itself is dual-licensed under MIT OR Apache-2.0 — those licenses govern your use of the code; these Terms govern your use of the hosted Services.

Terms of Service

Version 1.0.0 — Effective 2026-05-17

These Terms of Service ("Terms") govern your access to and use of the Pseudo project's public website at pseudo-lang.com, its documentation site at docs.pseudo-lang.com, and any associated services we operate from those domains (collectively, the "Services").

The Services are operated by Vladimir Dukelic and Silicon Youth LLC ("we", "us", "our"). The Pseudo project itself (the language, compiler, standard library, documentation, ADRs, and source code) is dual-licensed under MIT OR Apache-2.0 — those licenses govern your use of the code and are not changed by these Terms. These Terms govern your use of the hosted Services only.

1. Acceptance

By creating an account, joining the waitlist, submitting a form, or otherwise using the Services, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Services.

We may update these Terms from time to time. When we make a material change, we will (a) publish the new version at the same URL, (b) update the version number and effective date at the top of this document, and (c) for signed-in users, require you to re-accept the new version on your next visit. Continued use after the effective date of a new version constitutes acceptance.

2. Eligibility

You must be at least 16 years old to create an account or join the waitlist. If you are between 16 and the age of majority in your jurisdiction, you represent that your parent or legal guardian has reviewed and agreed to these Terms on your behalf.

If you are using the Services on behalf of an organization (an employer, school, agency, or other entity), you represent that you have authority to bind that organization, and "you" in these Terms refers to both you and that organization.

The Services are not directed at children under 16. If we learn that we have collected personal information from a child under 16 without verified parental consent, we will delete it.

3. License to use the Services

We grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Services for your personal or internal business purposes, subject to these Terms.

This license does not grant you any rights to:

  • the Pseudo trademarks, wordmarks, or logos beyond the fair-use carve-outs published at /brand (educational use, "Pseudo-compatible" descriptions, blog posts, talks, scoped package names, and similar nominative use)
  • the design, look-and-feel, or non-open-sourced portions of the website
  • any data or content owned by other users

You may freely use, modify, and redistribute the open-source Pseudo project under MIT OR Apache-2.0 — that is governed by those licenses, not by this section.

4. Your account

If you create an account, you are responsible for:

  • maintaining the confidentiality of your credentials
  • all activity that occurs under your account
  • promptly notifying us if you suspect unauthorized access

We use Better Auth for session management. Sessions are bound to a first-party, httpOnly, secure cookie scoped to our domain. We do not knowingly support shared accounts; each natural person should have their own account.

We may suspend or terminate accounts that we reasonably believe are being used to violate these Terms, infringe third-party rights, or threaten the security or integrity of the Services.

5. User-submitted content

When you submit content to the Services — feature requests, bug reports, waitlist signups, comments on community channels, or anything else — you represent that you have the right to submit it, and you grant us a worldwide, non-exclusive, royalty-free, irrevocable license to use, store, reproduce, modify, publish, and display that content for the purpose of operating, improving, and promoting the Services and the Pseudo project.

We have no obligation to store, display, or otherwise retain your submitted content, and we may remove it at any time without notice. For content that may become part of the public Pseudo project (issues, RFCs, pull requests on the public GitHub repository), the licensing terms of the relevant repository apply.

6. Acceptable use

You agree not to use the Services to:

  • violate any law, regulation, or third party's rights
  • infringe any patent, trademark, copyright, trade secret, or other intellectual-property right
  • transmit malware, spam, phishing content, or other harmful material
  • attempt to gain unauthorized access to any system, account, or data
  • circumvent or attempt to circumvent any security or rate-limiting measure (including but not limited to Cloudflare Turnstile and our anti-bot defenses)
  • harvest, scrape, or otherwise collect data from the Services for purposes we have not authorized
  • impersonate any person or misrepresent your affiliation with any person or organization
  • harass, abuse, or threaten any other person
  • interfere with or disrupt the integrity or performance of the Services
  • use any automated means (bots, scrapers, AI agents) to access the Services in a way that exceeds reasonable rate limits or violates our published machine-readable rules (robots.txt, agent allowlists, sitemap-declared crawl budgets)

We reserve the right to investigate and take legal action against anyone who, in our sole discretion, violates these provisions, including removing offending content, suspending accounts, and reporting to law enforcement.

7. Intellectual property

7.1 Our intellectual property

The Pseudo project — the language design, the compiler implementation, the standard library, the documentation, the ADRs, the spec — is owned and authored by Vladimir Dukelic, who retains all authorship rights, solo veto, and project ownership in perpetuity per the project's GOVERNANCE.md. The open-source license (MIT OR Apache-2.0) is a license choice, not an ownership transfer.

The Pseudo wordmark, the leading-dot logo (".pseudo"), the violet brand color, and the related brand assets are trademarks owned by Vladimir Dukelic. The full trademark policy publishes at v0.5; until then, fair-use carve-outs at /brand apply.

Silicon Youth LLC is the operating entity for commercial and infrastructure aspects of the project. References to "we" / "us" in these Terms refer jointly to Vladimir Dukelic and Silicon Youth LLC where applicable.

7.2 Your intellectual property

You retain all rights to content you create. Submitting content to the Services does not transfer ownership of that content to us — it grants us the license described in Section 5 to operate the Services.

7.3 Feedback

If you send us feedback — feature requests, bug reports, suggestions — we are free to use that feedback for any purpose without obligation or compensation to you. This is consistent with how open-source projects typically handle community input.

8. Third-party services

The Services rely on third-party providers (Supabase, Cloudflare, Vercel, Stripe, Resend, and others listed in our Privacy Policy). Your use of those third-party services is also subject to those providers' terms. We are not responsible for the acts, omissions, or terms of third parties.

Links from the Services to third-party websites are provided for convenience and do not constitute endorsement.

9. Disclaimers — the Services are provided AS IS

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT ANY WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that the Services will be uninterrupted, error-free, secure, or free of viruses or other harmful components. We do not warrant the accuracy or completeness of any content on the Services. The Pseudo project is pre-v1.0; everything ships as a work in progress until Vladimir personally tests and approves v1.0 Ludens.

Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions, the exclusions above apply only to the extent permitted by law.

10. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE, OUR AFFILIATES, OR OUR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR USE, ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR YOUR USE OF THE SERVICES, WHETHER BASED IN CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR THE SERVICES WILL NOT EXCEED ONE HUNDRED UNITED STATES DOLLARS (US$100). THIS LIMITATION APPLIES TO ALL CLAIMS, REGARDLESS OF THEIR BASIS.

The Services and the underlying Pseudo project are provided primarily as a free, open-source resource. The limitation above reflects the economic reality of that relationship and applies to the maximum extent allowed by law.

Some jurisdictions do not allow the limitation of liability for consequential or incidental damages; in those jurisdictions, the limitations above apply only to the extent permitted by law.

11. Indemnification

You agree to defend, indemnify, and hold harmless Vladimir Dukelic, Silicon Youth LLC, and their respective officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or in any way connected with (a) your access to or use of the Services, (b) your violation of these Terms, or (c) your violation of any third-party right.

12. Termination

You may stop using the Services at any time. If you have an account, you may delete it from your account settings; deletion is irrevocable.

We may suspend or terminate your access to the Services at any time, with or without notice, for any reason — including but not limited to violation of these Terms, suspected fraudulent or unlawful activity, or risk to the security or integrity of the Services.

Termination does not relieve you of obligations that by their nature survive termination — including but not limited to Sections 5 (license grants), 7 (intellectual property), 9 (disclaimers), 10 (limitation of liability), 11 (indemnification), and 13 (governing law).

Even after account deletion, we retain a record of your acceptance of these Terms (the tos_acceptance record — IP address, user agent, accepted version, timestamp) for the duration permitted under applicable law. That retention is necessary for evidentiary purposes (proving that consent was obtained) and is explained in the Privacy Policy.

13. Governing law and jurisdiction

These Terms are governed by the laws of [JURISDICTION TO BE FINALIZED — Vladimir to choose between (a) the Republic of Serbia, where Vladimir Dukelic resides, and (b) the State of Delaware, USA, where Silicon Youth LLC is registered, before this document is published outside pre-v1 contexts].

Any dispute arising out of or relating to these Terms or the Services will be resolved in the courts of the chosen jurisdiction, and you consent to the personal jurisdiction of those courts.

This section does not deprive you of mandatory consumer-protection rights granted to you by the laws of your country of residence; nothing in these Terms is intended to waive such rights to the extent they cannot be waived under applicable law.

14. Changes to these Terms

We may update these Terms from time to time. We will update the version number and effective date at the top of this page, and for material changes affecting signed-in users we will require re-acceptance on your next visit.

A change log of all published versions is available at /legal. Prior versions remain available for reference.

15. Miscellaneous

Entire agreement. These Terms, together with our Privacy Policy, constitute the entire agreement between you and us with respect to the Services and supersede any prior agreements on that subject matter.

Severability. If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions will remain in full force and effect.

No waiver. Our failure to enforce any provision of these Terms is not a waiver of that provision or any other.

Assignment. You may not assign or transfer these Terms or any of your rights or obligations under them without our prior written consent. We may assign these Terms freely.

Notices. We may give you notice by posting on the Services or by email to the address associated with your account. You may give us notice by emailing vladimir@pseudo-lang.com.

No agency. Nothing in these Terms creates an agency, partnership, joint venture, or employment relationship between you and us.
