Privacy Policy

Last updated September 28, 2026

The short version: arsenal.finance has no accounts, no sign-up and no login. It does not ask you who you are, it does not build a profile of you, and it does not sell or share anything about you with anyone. Everything below is the long version of that.

What the site does not do

  • No user accounts, passwords, or sign-up of any kind.
  • No advertising network, no ad pixels, no retargeting tags.
  • No selling, renting, or sharing of visitor data. There is no data business here.
  • No request for your name, address, phone number, income, portfolio, or any financial detail.

The numbers you type into the tools

Every calculator on this site runs entirely in your own browser. Your salary in the FIRE calculator, your balances in the net worth calculator, your loan terms in the mortgage calculator: none of it is ever sent to a server, never reaches the site owner, and is gone the moment you close the tab. It is arithmetic on your own machine.

My Arsenal and Daily Brief save information in this browser. This includes followed asset symbols, selected economic and real-estate indicators, fixed category assignments, saved learning widgets and calculator, chart ranges and collapsed states, visit and last-seen timestamps, comparison snapshots of prices, economic observations, model scores, momentum readings and disclosure IDs, and the dates of the economic releases the Daily Brief has already reported, so a release is described once rather than every day. A visit timestamp is recorded when a site page loads, even if data feeds fail. A browser session continues across pages; after 30 minutes away or in a new tab, saved observations become the comparison baseline.

These records are held in local storage and session storage. They are not uploaded as a personal profile, synced to an account, or sent to our analytics. They remain until you remove them, clear browser data or use “Clear My Arsenal & visit history” on My Arsenal. That control clears this feature’s saved selections and history; it does not clear unrelated display preferences or data caches. A subsequent visit starts recording again. Private browsing, blocked storage and browser cleanup may prevent persistence.

Fetching data does send the requested asset search text, ticker or economic-series identifier to our data proxies and providers. Widget selections and visit-comparison history are not included in those requests. The hosting and data providers may receive ordinary request metadata as described below. See the Data Policy for sources, refresh timing, snapshot limits and briefing methodology.

Server and CDN logs

The site is hosted behind a CDN, and like every web server on the internet it writes ordinary request logs: IP address, user agent, the URL requested, timestamp, and response status. These exist to serve the pages, block abuse, and diagnose outages. They are retained by the hosting and CDN providers under their own standard retention windows and are not used to build any profile or mailing list.

Analytics

The site uses privacy-preserving, cookieless analytics to see which pages get read and roughly where readers arrive from. They record page path, referrer, approximate country, device type and screen size. They do not set advertising cookies, do not track you across other websites, and do not receive anything that identifies you personally.

To learn whether readers find the site worth coming back to, your browser also keeps a small note in local storage: the day of your first visit, the section you first landed on, and the days you have visited since. At most once a day it sends the site an anonymous tally, such as "first visit" or "came back the next day", with no identifier attached, so the site can count return visits without knowing who anyone is. Clearing your browser data erases the note, and the opt-out below turns it off too.

If you would rather not be counted at all, there are two ways out and both of them work. Run any content blocker, which stops the analytics scripts reaching you in the first place. Or visit arsenal.finance/?notrack=1 once, which sets a permanent flag in this browser so those scripts never load again; visiting arsenal.finance/?track=1 undoes it.

Things you choose to send

Two places on the site accept input that actually leaves your browser, and both are entirely optional:

  • The feedback form. If you report a bug or send an idea, the message is delivered to the site owner. The email field is optional and exists only so there is a way to reply to you. It is never added to a mailing list.
  • The newsletter. Subscribing is handled by the newsletter platform, not by this site, and it is governed by that platform's own privacy policy. You can unsubscribe from any issue.

Third parties the pages talk to

Pages pull live numbers from outside providers: economic series from the Federal Reserve Bank of St. Louis, filings from the SEC, and market, crypto and commodity prices from commercial data feeds. Charts and fonts load from public CDNs. Because your browser makes those requests, those providers see your IP address and user agent, exactly as they would if you visited them directly. This site sends them nothing about you beyond the request itself.

Outbound links to other services, including the newsletter, the community server, the tip jar and every source document, leave this site entirely. Once you follow one, that service's own privacy policy applies.

Children

The site is not directed at children under 13 and does not knowingly collect anything from them. Since it collects no personal information from anyone, there is nothing held about a child to delete.

Your rights

Depending on where you live, you may have a legal right to access, correct, or delete personal data a site holds about you. In practice there is nothing here to access or delete: no account exists, and the analytics hold no record tied to you. If you have sent a message through the feedback form and want it removed, ask and it will be deleted.

Changes

This policy may change as the site changes. The version posted at this URL is always the current one, and the date at the top says when it was last revised.
