Privacy

Specific tooling recommendations for solo operators running a small internet business, with the trade-offs stated rather than hidden.

This page describes what this site does with your data. It describes the site as it is currently built, not as it might be built later.

What we collect

Nothing.

There is no analytics script, no tag manager, no session recorder, no heatmap, no newsletter form and no login. We set no cookies and no other client-side storage: no localStorage, no sessionStorage, no IndexedDB.

The calculators

Every calculator on this site runs entirely in your browser. The numbers you type are used to compute a result on the page you are looking at and are never transmitted anywhere, because there is nowhere for them to be transmitted to: this is a static site with no server-side code and no API.

Nothing you enter is stored either, which has a consequence worth stating: if you reload the page, your inputs are gone. That is a deliberate trade-off in favour of not holding your data.

The sitemap and IndexNow helper deserves a specific note, because it asks for a key that proves you control a domain. That key is generated in your browser using crypto.getRandomValues, is never sent to us, and is not recoverable by us. The tool cannot submit on your behalf; it produces a command for you to run yourself.

Server logs

The web server that delivers these pages records requests, as essentially all web servers do. Each entry contains your IP address, the time, the page requested, the HTTP status, your user agent and the referring page if your browser sent one.

These logs exist to keep the site online and to investigate faults and abuse. They are not joined to any other data, not used to build a profile of you, and not sold or shared. They are retained for 30 days and then deleted.

Third parties

No third-party script runs on these pages. Fonts and stylesheets are served from this domain, so loading a page here does not make a request to any other company.

Some outbound links to vendors are affiliate links, which means we may earn a commission if you buy something. Following one takes you to that company's site, where their privacy policy applies rather than ours. We have no visibility into what you do once you leave.

We do not currently serve advertising. If that changes, an advertising network will set cookies and this page will be updated to say so before any ad code is added, not after.

Your data rights

Under the GDPR and similar regimes you have the right to access, correct and delete data held about you. We mention this to be able to answer it honestly: we hold no personal data about you beyond time-limited server logs keyed to an IP address, so in practice there is nothing to export or correct.

If you want the log entries for your IP address deleted before the 30 days elapse, ask and we will delete them.

Contact

Raise an issue on the repository that publishes this site. There is no contact form here, for the same reason there is no newsletter: it would mean collecting something.

Changes

Material changes will be reflected in the date at the top of this page. Because the site is published from version control, the full history of this document is recoverable rather than silently overwritten.
