Privacy Policy

Last updated October 1, 2026.

Screw Fitment Database (screwfitmentdatabase.com) is published by DixonAppStudio LLC. This page explains what happens to information about you when you use the site. The short version: there are no accounts, no sign-up forms and no payments here, and we do not sell personal information.

What we collect

• Usage statistics (Google Analytics 4). When a page loads, Google Analytics records the page you viewed, how you arrived (for example a search engine), your approximate location derived from your IP address, your device and browser type, and events such as clicks on store links. It uses first-party cookies (named _ga and _ga_*) to tell visits apart. We use these reports only to see which pages and tools are useful. Google's own use of this data is described at policies.google.com/technologies/partner-sites.
• Server logs. Like every website, our hosting provider processes the technical details of each request (IP address, time, the page requested, browser) to deliver pages and protect the site from abuse.
• Email you send us. If you write to us, we keep your message and address so we can reply and, for corrections, fix the entry.

The calculators and tools run in your browser. The numbers you type into them are not sent to us.

Links to stores and affiliate links

Pages link to screws sold by TechSpareWarehouse, our own store (on techsparewarehouse.com, eBay and Amazon), and to Amazon. As an Amazon Associate we earn from qualifying purchases: Amazon links carry our Associates tag, and Amazon may set its own cookies when you follow one. When you leave this site, the store's own privacy policy applies. Our click tracking records which link was clicked (store, screw size, page), not who you are.

Your choices

• You can block or delete cookies in your browser settings; the site works the same without them.
• Google offers a browser add-on to opt out of Google Analytics: tools.google.com/dlpage/gaoptout.
• Depending on where you live (for example the EU, UK or California) you may have the right to ask what data we hold about you, to correct it or to have it deleted. Email us and we will answer within 30 days.

Children

The site is a hardware reference and is not directed at children under 13.
