Effective Date: February 1, 2026

DoorVault ("we", "us", "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, store, and share information when you use our property management tracking platform at doorvault.app ("Service").

1. Information We Collect

Account Information

When you create an account, we collect your username, email address, display name, and password (stored as a secure hash). We do not store passwords in plain text.

Property and Financial Data

You may enter property details, transaction records, mortgage information, tenant information, lease terms, management company details, documents, and other financial data. This information is provided voluntarily and is essential to delivering the Service.

Usage Data

We collect basic usage information such as login timestamps, pages visited, and feature usage to improve the Service. We do not use third-party analytics trackers.

2. How We Use Your Information

We use your information to:

• Provide, maintain, and improve the Service
• Generate financial reports, tax summaries, and portfolio analytics
• Power the AI assistant feature using your portfolio data as context
• Send account-related notifications (renewal reminders, security alerts)
• Respond to support requests
• Detect and prevent fraud or unauthorized access

3. Data Storage and Security

Your data is stored in encrypted databases. We use industry-standard security practices including HTTPS encryption in transit, hashed passwords, and access controls. While we take reasonable measures to protect your data, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.

4. Third-Party Services

We use the following third-party services:

• Anthropic (Claude AI) -- Powers the AI assistant feature. When you use the AI chat, relevant portfolio context is sent to Anthropic's API to generate responses. Anthropic does not use this data for training. See Anthropic's Privacy Policy.
• Payment Processor -- If you subscribe to a paid plan, payment is handled by a third-party processor. We do not store credit card numbers or banking details on our servers.

5. Data Retention

We retain your data for as long as your account is active. If you delete your account, we will delete your personal data and property records within 30 days. Certain data may be retained longer if required by law or for legitimate business purposes such as fraud prevention. Anonymized, aggregated data that cannot identify you may be retained indefinitely for analytics purposes.

6. Your Rights

You have the right to:

• Access -- Request a copy of the personal data we hold about you
• Export -- Download your property and financial data in standard formats (CSV)
• Correct -- Update or correct inaccurate information in your account
• Delete -- Request deletion of your account and associated data
• Restrict -- Request that we limit how we process your data

To exercise any of these rights, contact us at [email protected].

7. Cookies

DoorVault uses essential cookies required for authentication and session management. We do not use advertising cookies or third-party tracking cookies. These essential cookies are strictly necessary for the Service to function and cannot be disabled.

8. Data Sharing

We do not sell, rent, or trade your personal data to third parties. We may share data only when required by law, to protect our rights, to prevent fraud, or with service providers who assist in operating the Service (subject to confidentiality obligations). If you use household sharing, data is shared with members of your household as configured by you.

9. Children's Privacy

DoorVault is not intended for use by individuals under the age of 18. We do not knowingly collect personal information from children. If we learn that we have collected data from a child under 18, we will promptly delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we make material changes, we will notify you by email or through a notice within the Service at least 14 days before the changes take effect. The "Effective Date" at the top of this page indicates when the policy was last revised.
