Privacy Policy

1. Introduction

This Privacy Policy explains how ChatWork ("ChatWork," "we," "us," or "our") handles personal information when you visit our marketing site, create an account, use chat and workspace features, connect third-party plugins, or interact with billing and support.

By using the Service, you agree to this Privacy Policy and our Terms of Service. If you do not agree, please do not use the Service.

2. Who this policy applies to

This policy applies to individual users and, where an account is used on behalf of a company or team, to the organization that authorized that use. It covers information processed through chatwork.com, personal workspace subdomains we provide, and in-product settings such as Security, Billing, and plugin connections.

3. Information we collect

4. How we use information

We use personal information to:

• Create and secure your account, including subdomain routing where enabled.
• Provide chat, models, plugins, routines, Space storage, memory, and other features you request.
• Enforce plan limits (Free, Pro, Max) for models, uploads, memory, plugins, and related quotas shown in Settings.
• Process subscriptions, upgrades, downgrades, and tax or invoice requirements.
• Respond to support requests and communicate about service changes or security issues.
• Monitor, detect, and prevent fraud, abuse, and violations of our Terms.
• Improve and develop the Service, including debugging and analytics in aggregated or de-identified form where possible.

5. How we share information

We share information only as needed to operate the Service, comply with law, or with your direction:

• Service providers: Vendors that host infrastructure, authentication, databases, email, analytics, and customer support under contractual confidentiality and security obligations.
• AI & model partners: Providers that process inference requests when you use chat or agent features. Content you submit may be transmitted to these providers for the purpose of generating outputs.
• Payment processing: Stripe for checkout, subscriptions, and billing records.
• Plugins you connect: Third-party services you authorize via OAuth or similar, according to the scopes you approve.
• Legal & safety: When required by law, valid legal process, or to protect the rights, safety, and security of ChatWork, our users, or the public.
• Business transfers: In connection with a merger, acquisition, or sale of assets, subject to continued protection of personal information.

6. Data retention

We retain information for as long as your account is active or as needed to provide the Service, comply with legal obligations, resolve disputes, and enforce agreements.

You can delete chats, Space files, and saved memory from the product. Disconnect plugins in Settings. After you request account deletion, we remove active copies within a reasonable period, subject to backup cycles and legal retention requirements.

7. Your choices & rights

Depending on where you live, you may have rights to access, correct, delete, restrict, or port personal information, and to object to certain processing.

You can manage many controls in Settings (profile, security, billing, plugins, memory, and Space). For other requests, email our privacy team — we will verify your request and respond as required by applicable law.

• Export or deletion requests for personal data.
• Opt out of non-essential marketing emails where offered.
• Withdraw plugin connections at any time from Settings.

8. Cookies & similar technologies

We use cookies and local storage for authentication, security, preferences (such as theme), and basic analytics. You can control cookies through browser settings; disabling essential cookies may limit sign-in and core functionality.

9. Security

We use encryption in transit (HTTPS/TLS) for browser and API traffic and apply safeguards for data at rest appropriate to our cloud providers. No method of transmission or storage is completely secure; please use a strong password or passkey and keep credentials confidential.

10. International transfers

We may process information in countries other than where you live. When we transfer personal data internationally, we use appropriate safeguards such as standard contractual clauses or equivalent mechanisms where required by law.

11. Children's privacy

The Service is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided us data, contact us so we can delete it.

12. Changes to this policy

We may update this Privacy Policy from time to time. We will post the revised policy on this page and update the "Last updated" date. Material changes may be communicated by email or in-product notice where appropriate. Continued use after changes means you accept the updated policy.
