Privacy Policy

Effective Date: May 10, 2026  |  Last Updated: May 27, 2026

1. Introduction and Scope

Stash Management, LLC (“Company,” “we,” “us,” or “our”) respects your privacy and is committed to describing our practices transparently. This Privacy Policy (“Policy”) explains how we collect, use, disclose, retain, and otherwise process personal information and other data when you access or use the Stash Management platform, including all associated websites, applications, and services (collectively, the “Service”).

This Policy applies to all users of the Service, including visitors, registered account holders, and any individuals whose information we receive in connection with the Service. By accessing or using the Service, you acknowledge that you have read and understood this Policy. If you do not agree to this Policy, you must discontinue use of the Service.

2. Information We Collect

We collect information in the following categories:

2.1 Information You Provide Directly

  • Account registration data (name, email address, password or authentication credentials)
  • Profile and organizational information
  • Inventory and catalog data you upload or input
  • Payment and billing information (processed by our third-party payment processors)
  • Communications you send to us, including support requests
  • Any other content or information you choose to submit

2.2 Information Collected Automatically

  • Log data (IP address, browser type and version, operating system, referring URLs, pages visited, timestamps)
  • Device identifiers and technical characteristics
  • Usage data (features used, actions taken, session duration, click patterns)
  • Cookies and similar tracking technologies (see Section 6)
  • Aggregated and derived analytics data

2.3 Inventory and Collection Data

When you use the Service, we store the following types of collection data on your behalf:

  • Comic book and collectible inventory items, including titles, issue numbers, condition grades, and pricing information you enter
  • Cover images you upload and catalog cover images sourced from third-party providers (e.g., ComicVine)
  • Marketplace connection settings for platforms you authorize (e.g., eBay)
  • Activity logs of actions taken within your workspace (item additions, sales, enrichment requests)
  • AI integration tokens for connected assistants (see Section 7)

2.4 Information from Third Parties

  • Authentication data from OAuth providers (e.g., Google) when you use single sign-on
  • Comic metadata from catalog providers (e.g., ComicVine, Grand Comics Database) used to enrich your inventory records
  • Market pricing data from third-party pricing services you connect to the Service
  • Data from integrated marketplace platforms you connect to the Service
  • Publicly available information from third-party sources we use to supplement our records
  • Data from analytics and business intelligence partners

2.5 Market Pricing Data

To provide automated market price estimates for collectibles in your inventory, our Service periodically collects publicly available transaction and pricing data from third-party online marketplaces and pricing guides. This data consists solely of publicly accessible listing prices and historical sale prices — we do not collect, retain, or process any personal information about buyers, sellers, or other individuals from these sources.

All collected pricing data is aggregated and used only to compute estimated market values displayed within the Service. Our automated collection is limited to data that is publicly accessible without authentication. We comply with robots.txt directives published by source websites, rate-limit all automated requests to avoid imposing undue load on third-party systems, and identify our automated collector with a descriptive user-agent string. Pricing information displayed within the Service is for informational purposes only and does not constitute financial advice or a guarantee of value.

3. How We Use Your Information

We use the information we collect for the following purposes:

  • Providing, operating, maintaining, and improving the Service
  • Processing transactions and managing your account and subscription
  • Authenticating your identity and ensuring the security of your account
  • Communicating with you about the Service, including updates, security alerts, and support
  • Sending promotional and marketing communications (where permitted by law and subject to your preferences)
  • Analyzing usage patterns to understand how the Service is used and to optimize performance
  • Developing new products, services, features, and functionality
  • Complying with applicable legal obligations and enforcing our Terms of Service
  • Protecting the rights, property, and safety of the Company, our users, and the public
  • Conducting internal research, analytics, and business intelligence activities

  • Any other purpose disclosed at the time of collection or with your consent

4. Disclosure and Transfer of Your Information

We may disclose, transfer, license, or otherwise make available your personal information and other data to third parties in the following circumstances:

4.1 Service Providers

We engage third-party vendors and service providers that perform functions on our behalf, such as payment processing, data hosting, analytics, customer support, security services, and email delivery. These providers are granted access to information only as necessary to perform their functions and are subject to appropriate confidentiality obligations.

4.2 Business Partners and Commercial Arrangements

We may share, license, or transfer your information — including personal information, usage data, and behavioral data — with third-party business partners, data brokers, advertisers, analytics providers, and other commercial entities for purposes including but not limited to market research, targeted advertising, product development, and other lawful commercial activities. Such transfers may involve monetary or other consideration. Where required by applicable law, we will provide you with notice and, where applicable, an opportunity to opt out of such transfers.

4.3 Corporate Transactions

In the event of a merger, acquisition, reorganization, bankruptcy, dissolution, or sale of all or a portion of our assets, your information may be transferred to the acquiring or successor entity as part of such transaction. We will provide notice of any such transaction to the extent required by applicable law.

4.4 Legal Requirements and Protection of Rights

We may disclose your information when we believe in good faith that disclosure is necessary to: (a) comply with applicable law, regulation, legal process, or governmental request; (b) enforce our Terms of Service or other agreements; (c) protect the rights, property, or safety of the Company, our users, or the public; or (d) detect, prevent, or address fraud, security vulnerabilities, or technical issues.

4.5 Consent

We may disclose your information to any third party with your express consent.

5. Data Retention

We retain personal information for as long as necessary to fulfill the purposes for which it was collected, including for the purpose of satisfying applicable legal, accounting, or reporting requirements, and as otherwise permitted or required by law. We also retain de-identified, aggregated, or anonymized data indefinitely for analytical and business purposes. When determining the appropriate retention period, we consider the nature and sensitivity of the data, the potential risk of harm from unauthorized use or disclosure, and the purposes for which we process the data.

6. Cookies and Tracking Technologies

We use cookies, web beacons, pixels, local storage objects, and similar tracking technologies to collect information about your use of the Service, to maintain session state, to personalize your experience, and to support our analytics and marketing activities. We may also permit third-party analytics partners to set cookies through the Service.

6.1 Cookie Categories

  • Strictly necessary: Session and authentication cookies required for the Service to function. These are always active and cannot be disabled.
  • Analytics: Cookies that help us understand how users interact with the Service (e.g., page views, feature usage). We use Vercel Analytics for this purpose.
  • Marketing: Cookies that help us measure the effectiveness of our advertising campaigns and attribute conversions.

6.2 Geo-Aware Consent

We apply different consent defaults based on your location:

  • European Economic Area, United Kingdom, and Switzerland: We use an opt-in model. Analytics and marketing cookies are disabled by default. A consent banner will appear when you first visit the Service, and non-essential cookies will only be activated after you explicitly accept them.
  • United States (California and other states with applicable privacy laws): We provide a “Do Not Sell or Share My Personal Information” option. You may opt out of analytics and marketing cookies at any time by adjusting your preferences in the cookie banner or by contacting us.
  • All other regions: We use an opt-out model. Analytics and marketing cookies are enabled by default. You may opt out at any time through your browser settings or by contacting us.

Strictly necessary cookies are always active regardless of your location or consent choices, as they are required for the Service to function.

7. AI Integrations and MCP Connections

The Service supports connections to AI assistants (including Claude, ChatGPT, and other compatible AI tools) via the Model Context Protocol (MCP) standard and OAuth 2.0 authorization. This section describes how those connections work and what data they can access.

7.1 The Authorization Flow

When you connect an AI assistant to your Stash account, you will be directed to an authorization screen that identifies the requesting application, lists the permissions being requested, and asks for your explicit approval. No data is shared with the AI assistant until you click “Allow.” You may decline the connection at any time without affecting your Stash account.

7.2 What Connected AI Assistants Can Access

Once authorized, a connected AI assistant can access the following data from your account, limited to the permissions you approved:

  • Your inventory items (titles, issue numbers, condition, pricing, key issue flags)
  • Collection statistics (total count, total value, profit and loss summaries)
  • Recent activity in your workspace
  • Publisher breakdowns of your collection

If you authorize write permissions, a connected AI assistant may also add, update, or mark items as sold in your inventory. Write actions are always described to you before they are executed (dry-run preview), and you must confirm them explicitly.

7.3 Token Storage

Authorization tokens are stored securely in your Stash account and are associated with the specific AI application that requested them. Tokens are encrypted at rest. The AI assistant stores its own copy of the token locally on your device (managed by the AI application, not by Stash). Stash does not share your token with any party other than the AI assistant that initiated the authorization.

7.4 Revoking Access

You may revoke any AI integration at any time by visiting Settings → Connections in the Stash web application. Revoking a connection immediately invalidates the token — any subsequent API calls from that AI assistant will return an authorization error. Previously accessed data that the AI assistant has stored locally is outside of Stash’s control; refer to your AI assistant’s own privacy policy for how it handles cached data.

7.5 Data Sent to AI Providers

When you use an AI assistant with the Stash integration, queries you make and inventory data returned by the Stash MCP server may be processed by the AI provider (e.g., Anthropic for Claude, OpenAI for ChatGPT). This processing is governed by the AI provider’s own privacy policy, not by this Policy. We recommend reviewing the privacy policy of any AI assistant you connect to your Stash account.

8. Data Security

We implement commercially reasonable administrative, technical, and physical safeguards designed to protect your information against unauthorized access, disclosure, alteration, and destruction. However, no security system is impenetrable, and we cannot guarantee the absolute security of your information. We are not liable for any breach of security that occurs despite our reasonable precautions. You are responsible for maintaining the confidentiality of your account credentials and for any activity that occurs under your account.

9. Your Rights and Choices

Depending on your jurisdiction, you may have certain rights with respect to your personal information, including:

  • Access: The right to request information about the personal data we hold about you
  • Correction: The right to request correction of inaccurate or incomplete personal data
  • Deletion: The right to request deletion of your personal data, subject to applicable legal obligations and our legitimate business interests
  • Portability: The right to receive your personal data in a structured, machine-readable format
  • Opt-Out of Sale/Sharing: Residents of certain jurisdictions (including California) may have the right to opt out of the sale or sharing of their personal information for cross-context behavioral advertising. To exercise this right, please contact us using the information in Section 14
  • Marketing Opt-Out: The right to opt out of receiving promotional communications from us

To exercise any of these rights, please submit a request to us using the contact information provided in Section 12. We will respond to verifiable requests within the timeframes required by applicable law. We may need to verify your identity before processing your request, and we reserve the right to deny requests that we cannot verify or that are not required under applicable law.

10. Children’s Privacy

The Service is not directed to individuals under the age of thirteen (13), and we do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13 without verifiable parental consent, we will take steps to delete such information promptly. If you believe we may have inadvertently collected information from a child under 13, please contact us immediately.

11. International Data Transfers

We are based in the United States, and your information may be transferred to, stored, and processed in the United States or other countries where our service providers operate. These countries may have data protection laws that differ from the laws of your country. By using the Service, you consent to the transfer of your information to countries outside your country of residence, including the United States.

12. Changes to This Policy

We reserve the right to update or modify this Policy at any time and in our sole discretion. When we make material changes, we will update the “Last Updated” date at the top of this Policy and, where required by applicable law, provide additional notice. Your continued use of the Service after the effective date of any modified Policy constitutes your acceptance of the modified Policy. We encourage you to review this Policy periodically.

13. Contact Us
