DefenseTools.app

How DefenseTools.app handles your data

Everything runs in your browser

Every DefenseTools calculator runs entirely on your device. There is no backend, no database, and no API. Your inputs — including any defendant name, case number, charges, or dates you enter — are never transmitted anywhere. Every calculation happens client-side in JavaScript.

What's stored on your device

DefenseTools.app sets no cookies and stores nothing in your browser. The information you enter — including any defendant name, case number, or dates — lives in the page only while you're working and is gone the moment you close the tab, unless you deliberately save it to a .misg case file.

Saving case files (.misg)

Any tool that supports it can save your work as a portable .misg file. Three things to know:

  • The file is written wherever you choose to put it. It never goes through a server.
  • You can optionally encrypt it with a passphrase. Under the hood that's AES-GCM-256 with a key derived from your passphrase via PBKDF2-HMAC-SHA256 (600,000 iterations, per OWASP guidance) — so even if the file leaks, it can't be read without the passphrase.
  • Passphrase loss = data loss.We can't recover it for you.

Generating PDFs

PDFs are rendered entirely in your browser. Nothing is uploaded — the document is built from the same data already on your screen.

Analytics

We use Cloudflare Web Analytics for anonymous, aggregate page-view counts. It is cookieless and does not track, fingerprint, or build a profile of individual visitors.

Hosting and server logs

Like any website, DefenseTools.app is served through Cloudflare, our hosting and security provider. To deliver and protect the site, Cloudflare automatically logs standard request metadata such as IP address, timestamp, and the page requested. We don't control that logging, don't use it to identify you, and never combine it with anything you type into a tool. It is governed by Cloudflare's privacy policy.

No accounts, no cookies, no third-party trackers

There's no login and no account to create. We set no cookies. Fonts are served from this site, not a third-party CDN, and there are no advertising or tracking scripts of any kind.

Built by criminal defense attorneys

DefenseTools.app is built by Sorin & Pyle, Trial Lawyers, in Holland, Michigan. We built these tools for our own practice and made them free for the rest of the Michigan defense bar.
