Privacy Policy

Strap Index (watchstrapsize.com) doesn't ask you to sign up, log in or hand over personal details. This page explains the little data that is involved in running the site.

What we store on your device

The measuring tool remembers your screen calibration in your browser's local storage so you don't have to redo it. It never leaves your device.

Advertising (Google AdSense)

We show ads served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and/or other sites on the internet.

You can opt out of personalised advertising in Google Ads Settings, or opt out of some third-party vendors' use of cookies at aboutads.info. Learn more in How Google uses information from sites that use its services.

Visitors in the UK, EEA and Switzerland are asked for consent through Google's certified consent message before personalised ads or advertising cookies are used. You can change your choice at any time via Privacy & cookie choices (also in the footer).

Amazon affiliate links

Some links go to Amazon. As an Amazon Associate we earn from qualifying purchases. When you follow one, Amazon may set cookies to attribute the purchase — that's governed by Amazon's privacy notice.

Hosting

The site is served by Cloudflare, which processes standard technical data (such as IP address and browser type) to deliver pages and protect against abuse.
