Investment Vault
Ownership history,
reconstructed from evidence.
A privacy-first product for reconstructing source-linked investment records from the documents you already have.
Product
Your Ownership History, Reconstructed Document by Document
Investment Vault turns supported brokerage statements and related PDFs into candidate events for your review. Confirmed events remain linked to their source documents and are protected by SHA-256 and SHA3-256 integrity checks, an append-only audit trail, and preserved chain-of-custody records. This helps you reconstruct ownership history, identify potential gaps, and export a tamper-evident, source-linked record—all processed locally on your device.
How It Works
Three Steps to a Source-Linked Ownership History
Import supported statements, review extracted events, and build a source-linked ownership history—processed locally on your device.
- 01
Import supported records
Bring in text-based PDF brokerage statements and related supported documents. Processing stays on your device.
- 02
Review candidate events
Examine extracted details. Edit, confirm, reject, or defer each candidate before it becomes part of your ownership record.
- 03
Build and preserve the source-linked history
Confirmed events remain linked to supporting documents, with integrity checks and an append-only audit trail you can review.
Missing Records Leave Gaps. Investment Vault Helps You Find Them.
Investment Vault can identify potential gaps and inconsistencies based on the statements and confirmed events you provide. It does not invent missing records or claim certainty where evidence is incomplete.
Integrity
Tamper-Evident Protections Around the Record
Integrity controls help expose unauthorized changes and detect mismatches. They do not claim that tampering is impossible.
SHA-256
Integrity checks help verify that supporting records match the fingerprints preserved with your history.
SHA3-256
A second hash family strengthens mismatch detection across stored evidence and confirmed events.
Append-only audit history
Review activity is recorded in an append-only trail so prior actions remain inspectable over time.
Source-linked records
Confirmed ownership events stay connected to the documents that support them.
Chain-of-custody preservation
Preserved custody records help you understand how evidence moved through review and confirmation.
Integrity mismatch detection
When fingerprints no longer align, Investment Vault can surface mismatches instead of silently accepting change.
Local processing
Supported records are processed on your device. Dog House Ventures does not receive those imported records through the app.

How does Investment Vault protect record integrity?
Confirmed events remain linked to their source documents and are protected by SHA-256 and SHA3-256 integrity checks, an append-only audit trail, and preserved chain-of-custody records. These controls are tamper-evident and can detect integrity mismatches; they do not claim that tampering is impossible.
How are my records stored?
