Terms of Use

Last updated: April 16, 2026

These Terms of Use (“Terms”) constitute a legal agreement between you (“you” or “User”) and Cognfy LLC (“Cognfy,” “we,” “us,” or “our”), governing your use of the Nexus bookmark management application and service, including the website at stash.nexus, mobile applications, browser extensions, and related services (collectively, the “Service”).

By creating an account or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. License Grant

Subject to your compliance with these Terms, Cognfy grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Service on devices you own or control, as permitted by the applicable platform's usage rules. You may not distribute, sublicense, lease, or lend the Service to any third party. If you sell or transfer a device on which the Service is installed, you must remove the application first.

You may not copy (except as permitted by this license), reverse-engineer, disassemble, attempt to derive the source code of, modify, or create derivative works of the Service or any part thereof, except to the extent that such restriction is prohibited by applicable law.

2. Account Registration and Security

To use the Service, you must create an account. You agree to:

  • Provide accurate, current, and complete information during registration
  • Maintain the security of your password and API tokens
  • Promptly notify us of any unauthorized access to your account
  • Accept responsibility for all activity that occurs under your account

We reserve the right to disable accounts that we reasonably believe violate these Terms.

3. Account Deletion

You may delete your account at any time from the Settings page within the Service. Upon deletion, all data associated with your account is permanently removed, including bookmarks, collections, tags, friend connections, shared collection permissions, notifications, API tokens, saved searches, visit history, and uploaded images. Account deletion is immediate and irreversible.

You may also request account deletion by emailing [email protected].

4. User Content

“User Content” means any data you submit to the Service, including bookmarks, collections, tags, notes, profile information, and uploaded images.

Ownership

You retain ownership of your User Content. Cognfy does not claim ownership of any content you submit to the Service.

License to Cognfy

By submitting User Content, you grant Cognfy a worldwide, non-exclusive, royalty-free license to use, store, display, reproduce, and transmit your User Content solely for the purpose of operating, maintaining, and providing the Service to you and, where applicable, to users with whom you have chosen to share content. This license terminates when you delete your User Content or your account.

Linked Content

Bookmarks saved to the Service contain links to third-party websites. Cognfy does not control, endorse, or assume responsibility for the content, privacy policies, or practices of any third-party websites. You acknowledge and agree that Cognfy is not liable for any damage or loss caused by your use of or reliance on any third-party content accessed through bookmarks stored in the Service.

5. Acceptable Use

You agree not to use the Service to:

  • Violate any applicable law, regulation, or third-party rights
  • Store, share, or distribute content that is unlawful, harmful, threatening, abusive, defamatory, obscene, or otherwise objectionable
  • Store or distribute material that infringes any intellectual property rights
  • Harass, abuse, stalk, or threaten any other user
  • Impersonate any person or entity
  • Interfere with or disrupt the Service or its infrastructure
  • Attempt to gain unauthorized access to the Service, other accounts, or related systems
  • Use automated means (bots, scrapers, crawlers) to access the Service beyond the provided API, except with prior written permission
  • Circumvent rate limits or other technical restrictions
  • Use the Service for any form of spam or unsolicited communication

We reserve the right to remove content and suspend or terminate accounts that violate these terms, at our sole discretion and without prior notice.

6. Social Features and Sharing

The Service includes social features such as friend connections and collection sharing. By using these features, you agree that:

  • Friend connections require mutual consent (one user sends a request, the other accepts)
  • Either party may remove a friend connection at any time, which also revokes all shared collection access between them
  • When you share a collection, the recipient can view (and, with “collaborate” permission, add to) its contents
  • You are responsible for the content in collections you share
  • Making a collection public means anyone with the link can view it

7. API Access and Tokens

The Service provides API access via personal API tokens. You are responsible for keeping your API token secure. Treat your token like a password. Cognfy reserves the right to revoke API tokens or impose usage limits at any time. You agree not to share your API token with unauthorized parties or use it in a way that degrades the Service for other users.

8. Intellectual Property

The Service, including its design, code, graphics, logos, and trademarks, is owned by Cognfy LLC and protected by intellectual property laws. These Terms do not grant you any right to use Cognfy's trademarks, logos, or branding without prior written consent.

9. Copyright Infringement (DMCA)

If you believe that content available through the Service infringes your copyright, please send a notice to [email protected] containing:

  • A description of the copyrighted work you claim has been infringed
  • A description of the material you claim is infringing and its location in the Service
  • Your contact information (name, address, telephone number, email)
  • A statement that you have a good faith belief that the use is not authorized by the copyright owner
