OpenCaseLaw Word Add-in — Effective March 28, 2026

1. Provider

This add-in is provided by OpenCaseLaw, operated by Jonas Hertner.
Website: opencaselaw.ch
Contact: team@jonashertner.com

2. What the add-in does

The OpenCaseLaw Word Add-in lets you look up Swiss court decisions and statute articles and insert citations directly into your Word document. Optional Pro features use AI to verify references, find similar decisions, and find supporting decisions.

3. Data we process

We process data only when you explicitly trigger an action:

Search queries. When you type a search and press Enter (or click Search), your query text is sent to our API server at mcp.opencaselaw.ch.
Document selection (Find Related / Verify Reference). When you click "Find related" or "Verify reference," the currently selected text in your document is read and sent to our API server. No other part of your document is accessed.
Pro license key. If you subscribe to Pro, your license key is stored in your browser's localStorage and sent to our server for validation. It is never shared with third parties.

4. Pro features (AI-assisted)

When you use the Pro features (Verify reference, Find similar, Find supporting decision, Scan & verify), your selected text is sent to our server, which forwards it to Anthropic's Claude (Sonnet) for analysis. The text is processed in real time and is not stored by us or by Anthropic beyond the duration of the API request. The Scan feature reads the full document text to extract citations. Anthropic's data usage policy applies: anthropic.com/privacy.

5. No tracking

The add-in does not use cookies, analytics, tracking pixels, or any form of behavioral monitoring. It sends one optional, anonymous usage signal: a monthly-rotating install-cohort hash used solely to estimate the number of active installations. The hash changes every month and cannot be linked across months or to you; you can disable it at any time under Settings → Anonymous usage signal, and the add-in works identically without it. Details are in the OpenCaseLaw privacy notice.

6. Personal data

We do not collect personal data from free-tier users. For Pro subscribers, we store only the email address provided during checkout. All payment processing is handled by Stripe — we never receive or store credit card numbers or bank details.

7. Third parties

Your data is sent only to our own API server (mcp.opencaselaw.ch). The only third-party sub-processor is:

Anthropic (Claude Sonnet) — for Pro features (verify, find similar, find supporting, scan).
Stripe — for Pro payment processing only.

No data is sold, shared with advertisers, or used for any purpose beyond providing the service.

8. Data location

Our API server is hosted by Hetzner in Germany. Data transmitted to Anthropic is processed according to Anthropic's infrastructure policies.

9. Data retention

Search queries and document text are processed in real time. Document text is never stored on our server. When semantic re-ranking runs, the query text (200 characters at most) is recorded in an internal quality log — with no IP address, no user ID and no session reference, so entries cannot be attributed to you or to one another — and is automatically deleted per the retention period stated in the OpenCaseLaw privacy notice. Pro subscriber email addresses are retained for the duration of the subscription and deleted upon cancellation.

10. Your rights

You may request access to, correction of, or deletion of any personal data we hold by writing to team@jonashertner.com.

11. Changes to this policy

We may update this policy from time to time. The effective date at the top of this page will be revised accordingly. Continued use of the add-in after changes constitutes acceptance of the updated policy.

This policy is written in English. German, French, and Italian versions are available on request at team@jonashertner.com.
