Tax Terrier Privacy Policy
Hansa Works LLC · Effective November 5, 2026
This policy explains how the Tax Terrier desktop app ("the app") handles information. Hansa Works LLC, a Utah limited liability company ("we"), makes the app.
Who can use the app
The app is for accounting firms that have a written agreement with us. We give accounts only to people at those firms. Anyone can install the app, but it does nothing without an account.
If your firm's agreement with us differs from this policy, the agreement controls.
What the app does
The app reads tax documents, such as W-2 forms, from a folder on your computer that you choose. It extracts information from them, shows it to you for review, and enters the approved information into your firm's Lacerte tax software. Nothing goes into Lacerte until a person approves it.
Information we process
- Account information. Your email address and password, which Google Identity Platform manages for us. We never see your password.
- Documents. When you start a run, the app sends each document in your chosen folder for text recognition and data extraction. These documents contain tax information, such as names, addresses, Social Security numbers, employer or payer details, and income and tax amounts.
- Service logs. Our cloud services keep standard request logs, such as the time, the IP address, and whether a request succeeded. These logs do not contain document content.
Who processes documents
Documents go only to these service providers, and only in the United States:
| Provider | Service | Purpose |
|---|---|---|
| Google Cloud | Identity Platform | Sign-in and accounts |
| Google Cloud | Document AI | Reading the text and form fields in documents |
| Google Cloud | Cloud Run | Our service that connects the app to the extraction models |
| Amazon Web Services | Bedrock | AI models that identify documents and extract information from them |
We use the AI models to read and organize information that is in the documents. They do not give tax advice or make tax decisions. Under their terms, these providers do not use this data to train their models.
What we keep
On our servers: only your account (email address and sign-in records) and the service logs described above. Documents and the information extracted from them pass through our services during a run and are not stored.
On your computer: the app keeps these in your Windows user profile:
- Your settings and saved sign-in, encrypted with Windows Data Protection.
- A record of which documents it has already handled. This record uses a fingerprint (hash) of each file, and encrypts the file paths and error messages.
- Log files that help with support. They name clients only by name and client ID. The app makes one log file per day and keeps only the newest 30.
Information you approve is entered into your firm's Lacerte data, which your firm controls.
What we do not do
- We do not sell or rent information.
- We do not use information for advertising.
- The app does not include analytics, tracking, or crash reporting.
- We do not share information with anyone except the providers above, or when the law requires it.
Security
- All data sent over the internet is encrypted (HTTPS/TLS).
- Only signed-in users can use our cloud services, and we create every account ourselves.
- Data on your computer that can identify a client is encrypted or kept out of the logs.
- A person reviews and approves every entry before the app writes it to Lacerte.
Your firm's responsibilities
Your firm remains responsible for its own obligations to its clients, including under Internal Revenue Code section 7216 and the FTC Safeguards Rule. Your firm decides which documents to process.
Deleting your information
- Uninstalling the Microsoft Store version of the app removes the data it stored on your computer.
- To close your account and remove your account information, email us at the address below.
Children
The app is for professionals. It is not for children, and we do not knowingly collect information from children.
Changes to this policy
If we change this policy, we will post the new version here and change the effective date. If a change is important, we will also tell the firms we have agreements with.
