Effective February 20, 2026

Soleur -- Company-as-a-Service Platform

Effective Date: February 20, 2026

Last Updated: March 20, 2026 -- added Web Platform service terms, scoped local-only statements to Plugin, updated data practices and GDPR rights sections for Web Platform; added subscription cancellation, refund, and EU withdrawal policy (Section 5); added Article 12(3) two-month extension provision to response timeline.

1. Introduction and Acceptance

These Terms & Conditions ("Terms") govern your access to and use of the Soleur platform ("Soleur," "the Plugin," "the Service") and the Soleur Web Platform at app.soleur.ai ("the Web Platform"), Company-as-a-Service products developed and maintained by Jikigai ("we," "us," "our"), a company incorporated in France with its registered office at 25 rue de Ponthieu, 75008 Paris, France. Soleur is a Claude Code plugin that provides AI-powered agents, skills, commands, and a compounding knowledge base for structured software development workflows. The Web Platform is a cloud-hosted companion service providing account management, workspace environments, and subscription services.

By installing, accessing, or using Soleur (whether the Plugin or the Web Platform), you ("User," "you," "your") agree to be bound by these Terms. If you do not agree to these Terms, do not install or use the Plugin or the Web Platform.

These Terms apply to all Users globally, with specific provisions for Users in the European Union / European Economic Area (EU/EEA) under the General Data Protection Regulation (GDPR) and Users in the United States.

2. Definitions

  • "Plugin" refers to the Soleur Claude Code plugin, including all agents, skills, commands, configuration files, and knowledge-base components.
  • "Knowledge Base" refers to the locally stored collection of brainstorms, plans, specs, learnings, and other artifacts generated during use.
  • "Documentation Site" refers to the website hosted at soleur.ai on GitHub Pages.
  • "Third-Party Services" refers to external services accessed through or in connection with the Plugin, including but not limited to the Anthropic Claude API, GitHub, and GitHub Pages.
  • "Account Data" refers to email address, authentication tokens, session data, and other information provided during Web Platform registration and use.
  • "Subscription" refers to a paid plan for Web Platform access, managed through Stripe Checkout.
  • "User Content" refers to all data, files, configurations, and artifacts created, modified, or stored by the User through the Plugin.
  • "Web Platform" refers to the Soleur cloud-hosted service at app.soleur.ai, including account management, workspace environments, and subscription services.

3. Eligibility

You must be at least 18 years of age (or the age of majority in your jurisdiction) to use the Plugin or the Web Platform. By using Soleur, you represent and warrant that you meet this requirement.

If you are using the Plugin or the Web Platform on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.

4. Description of the Service

Soleur is a locally installed Claude Code plugin that provides:

  • 65 AI agents organized across 8 domains (Engineering, Finance, Legal, Marketing, Operations, Product, Sales, Support)
  • 67 skills for structured software development workflows
  • A compounding knowledge base that stores project context locally
  • Commands for orchestrating development workflows (brainstorm, plan, review, work, ship)

4.1 Local-First Architecture

The Plugin is installed and operates locally on your machine via the Claude Code CLI. All knowledge-base files, configuration data, and Plugin-generated User Content are stored exclusively on your local file system. The Plugin does not collect, transmit, or store your data on remote infrastructure controlled by us.

This section applies to the Plugin only. For the Web Platform, see Section 4.3 below.

4.2 Third-Party API Interactions

The Plugin facilitates interactions with the Anthropic Claude API and other third-party services. These interactions occur through your own API keys and accounts. You are solely responsible for:

  • Maintaining the security of your API keys and credentials
  • Complying with the terms of service of all third-party providers
  • Any costs or charges incurred through third-party API usage

4.3 Web Platform Service

The Soleur Web Platform at app.soleur.ai is a cloud-hosted service operated by Jikigai. Unlike the Plugin (Section 4.1), the Web Platform processes data on Jikigai-operated infrastructure.

When you create a Web Platform account:

  • You provide an email address and authenticate via magic link or an OAuth provider (Google, Apple, GitHub, or Microsoft). Authentication credentials are managed by Supabase. If you use OAuth, your provider user ID, display name, and profile picture URL are stored. Accounts with matching verified email addresses are automatically linked.
  • You may store encrypted API keys (BYOK -- bring your own key) in your workspace.
  • If you subscribe to a paid plan, payment is processed by Stripe via Stripe Checkout. Card data is handled exclusively by Stripe and never reaches Jikigai servers.

The Web Platform is hosted on Hetzner servers in Helsinki, Finland (EU) and uses Cloudflare as a CDN/proxy. Full data processing details are described in the Privacy Policy Section 4.7.

By creating a Web Platform account, you accept these Terms and acknowledge that your data will be processed as described in the Privacy Policy. Acceptance requires checking the "I agree to the Terms & Conditions and Privacy Policy" checkbox on the signup page before account creation. The checkbox is unchecked by default; you must actively check it to proceed. Your acceptance is timestamped and recorded.

5. Subscriptions, Cancellation, and Refunds

Subscriptions renew automatically at the end of each billing period (monthly or annually, as selected at checkout) unless cancelled.

5.1 Cancellation

You may cancel your Subscription at any time. Cancellation takes effect at the end of the current billing period. You will retain access to paid features until the end of the period for which you have already paid.

5.2 Account Deletion with Active Subscription

If you delete your Web Platform account while a Subscription is active, the deletion triggers cancellation of your Subscription effective at the end of the current billing period. Account data is deleted as described in Section 14.1b.

5.3 EU Right of Withdrawal

If you are a consumer in the EU/EEA, you have a 14-day right of withdrawal under Directive 2011/83/EU. However, by subscribing and requesting immediate access to the Web Platform's paid features, you expressly consent to the performance of the digital service beginning immediately and acknowledge that you thereby waive your right of withdrawal in accordance with Article 16(m) of Directive 2011/83/EU. If you do not consent to immediate access, your access to paid features will begin after the 14-day withdrawal period has expired, during which you may withdraw and receive a full refund. To exercise your right of withdrawal, contact [email protected] or use the model withdrawal form available upon request.

5.4 Refunds

Except as required by applicable law (including the EU right of withdrawal described in Section 5.3), all Subscription fees are non-refundable. Jikigai may, at its sole discretion, issue refunds or credits on a case-by-case basis. Any discretionary refund does not entitle you to future refunds in similar circumstances.

6. License and Intellectual Property

6.1 License Grant

The Plugin is licensed under the Business Source License 1.1 (BSL 1.1). Subject to your compliance with these Terms and the BSL 1.1 license, you may copy, modify, create derivative works, redistribute, and make production use of the Plugin for your personal or internal business purposes.

6.2 Restrictions

You shall not:

  • Offer the Plugin to third parties on a hosted or managed basis in order to compete with Jikigai's commercial offerings
  • Reverse engineer, decompile, or disassemble the Plugin except as expressly permitted by applicable law (including EU Directive 2009/24/EC on the legal protection of computer programs)
  • Remove, alter, or obscure any proprietary notices, labels, or marks
  • Use the Plugin in any manner that violates applicable laws or regulations

Each version of the Plugin converts to the Apache License 2.0 four years after its publication date. Prior versions (v3.0.10 and earlier) remain under the Apache License 2.0.

6.3 User Content Ownership

You retain all rights, title, and interest in your User Content. We claim no ownership over any files, knowledge-base entries, code, or artifacts generated or stored on your local machine through use of the Plugin. For the Web Platform, you retain all rights to data you store in your workspaces, including encrypted API keys and workspace configurations.

6.4 Our Intellectual Property

All rights, title, and interest in and to the Plugin (including agent definitions, skill configurations, command logic, and documentation) remain with us. These Terms do not grant you any rights to our trademarks, service marks, or trade names.

6.5 Contributor Intellectual Property

If you contribute code or other materials to the Soleur project via pull requests, you must sign a Contributor License Agreement (CLA) before your contribution can be accepted. The CLA grants Jikigai a perpetual, irrevocable license to use, modify, sublicense, and relicense your contribution, while you retain your copyright. The CLA includes an express patent grant covering contributed code. Full terms are set out in the Individual Contributor License Agreement and Corporate Contributor License Agreement.

7. AI-Generated Output

7.1 Nature of AI Output

Soleur leverages AI models to generate code, documentation, legal document drafts, plans, reviews, and other content. All AI-generated output is provided on an "as-is" basis and:

  • May contain errors, inaccuracies, or omissions
  • Does not constitute professional advice (legal, financial, technical, or otherwise)
  • Requires human review and validation before use in production or business-critical contexts

7.2 Legal Document Generation

The Plugin includes a legal document generation capability. Documents generated by this feature are explicitly marked as drafts requiring professional legal review. These generated documents do not constitute legal advice and should not be relied upon without review by a qualified legal professional.

7.3 Responsibility for Output

You are solely responsible for reviewing, validating, and assuming liability for any AI-generated output you choose to use, publish, deploy, or distribute.

8. Data Practices and Privacy

8.1 Local Data Storage

Soleur operates on a local-first model. The Plugin itself does not collect, transmit, or store personal data on external servers. All User Content, configuration files, and knowledge-base entries remain on your local machine under your control.

This section applies to the Plugin only. For Web Platform data practices, see Section 8.1b and the Privacy Policy Section 4.7.

8.1b Web Platform Data Practices

The Soleur Web Platform collects and processes personal data as necessary to provide the service. This includes:

  • Account data (email, authentication tokens) processed by Supabase (EU-hosted, AWS eu-west-1, Ireland).
  • Payment data processed by Stripe (PCI SAQ-A -- card data handled exclusively by Stripe).
  • Workspace data (encrypted API keys, workspace configurations) hosted on Hetzner (Helsinki, Finland, EU).
  • Technical data (IP addresses, request headers) processed by Cloudflare CDN/proxy.

For comprehensive data processing details, legal bases, retention periods, and your rights, see the Privacy Policy and GDPR Policy.

8.1c Shared Content

The Web Platform allows you to share individual knowledge base documents via public links. By using this feature:

  • Your responsibility: You are solely responsible for the content you choose to share. You must ensure that shared documents do not contain confidential third-party information, personally identifiable information of others without their consent, or material that infringes third-party intellectual property rights. See the Acceptable Use Policy for detailed rules.
  • Jikigai's role: Jikigai acts as a processor making the document content available at the shared URL on your instruction. Jikigai does not review, moderate, or approve shared content prior to publication.
  • Revocation: You may revoke a share link at any time from the Web Platform. Revocation takes immediate effect. However, Jikigai cannot guarantee that recipients have not copied, downloaded, or redistributed the content prior to revocation.
  • No warranty of recipient conduct: Jikigai makes no representation regarding how recipients will use shared content and accepts no liability for any downstream use by recipients.

8.2 Documentation Site

The Soleur documentation site (soleur.ai) is hosted on GitHub Pages. GitHub, as the hosting provider, may collect certain data such as IP addresses and browser metadata in accordance with GitHub's own privacy practices. We do not control GitHub's data collection. Please refer to GitHub's Privacy Statement for details.

8.3 Third-Party Data Processing

When the Plugin facilitates interactions with the Anthropic Claude API or other third-party services, data transmitted to those services is governed by their respective privacy policies and terms of service. We are not responsible for the data practices of third-party service providers.

8.4 EU/EEA Users -- GDPR Rights

If you are located in the EU/EEA, you have rights under the GDPR including the right of access, rectification, erasure, restriction of processing, data portability, and objection.

For the Plugin, these rights are inherently satisfied by your local control over Plugin-generated data.

For the Web Platform, you may exercise these rights against Jikigai by contacting [email protected]. See the GDPR Policy Section 5 for full details on how to exercise each right.

For any GDPR-related inquiries concerning the documentation site or third-party integrations, please contact us through the channels listed in Section 17.

9. Acceptable Use

You agree to use the Plugin and the Web Platform only for lawful purposes and in accordance with these Terms. You shall not use the Plugin or the Web Platform to:

  • Introduce malware, viruses, or other harmful code
  • Circumvent, disable, or interfere with security features of the Plugin or connected services

14.1 Termination by You

You may stop using the Plugin at any time by uninstalling it from your Claude Code environment. No notice to us is required.
