Privacy Policy

Last updated: September 2026

Overview

Computezy is a collection of free, client-side tools. We do not collect, store, or transmit any personal information you enter. Everything each tool does happens entirely in your browser. Third-party analytics and advertising services used on this site may set their own cookies, as described below.

Data we do not collect

  • We do not collect your name, email address, or any contact information
  • We do not track your inputs, measurements, or usage patterns
  • We do not create user accounts or user profiles
  • We do not sell data to third parties โ€” there is no data to sell

Local storage

Some tools save your preferences to your browser's localStorage so your settings persist between visits. This data never leaves your device. Examples include:

  • Your colour theme preference (light or dark mode)
  • Calibration settings and measurement units for the online ruler
  • Timer configurations and round settings for the HIIT and interval walking timers
  • Any other per-tool preferences you configure

You can clear this data at any time by clearing your browser's site data for this domain.

Google Analytics

This site uses Google Analytics to understand aggregate traffic patterns (page views, referrers, general geographic region). Google Analytics uses cookies and may process your IP address. No personally identifiable information is collected or shared with us. See Google's Privacy Policy for details. You can opt out using the Google Analytics Opt-out Browser Add-on.

Advertising

Computezy is free because it is supported by advertising. We may display ads served by third-party advertising partners, including Google and ad networks such as Ezoic and EthicalAds. These partners may use cookies, web beacons, and similar technologies to serve ads based on your prior visits to this and other websites, to limit how often you see an ad, and to measure ad performance.

  • Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and other sites on the internet. You can opt out of personalised advertising in Google Ads Settings, and read how Google uses data from partner sites.
  • You can opt out of personalised advertising from many third-party vendors at aboutads.info or, in Europe, youronlinechoices.eu.
  • Visitors in the EEA, UK, and Switzerland will be asked for consent before personalised advertising cookies are set, and can change that choice at any time.

Ad partners never receive the values you enter into our tools โ€” those stay in your browser.

Affiliate links

Some pages contain affiliate links. If you follow one and make a purchase, we may earn a commission at no extra cost to you. Affiliate partners may set cookies to attribute the referral. We only link to products relevant to the tool you are using.

Google Fonts

This site loads fonts (Inter and JetBrains Mono) from Google Fonts. When your browser requests these fonts, Google may log your IP address as part of their standard server logging. See Google's Privacy Policy for details.

Hosting

This site is hosted on Cloudflare Pages. Cloudflare may collect standard server access logs (IP addresses, request timestamps, and URLs) for security and operational purposes. These logs are not accessible to us for tracking individual users.

Changes to this policy

If this policy changes materially, we will update the "Last updated" date at the top of this page. Continued use of the site after changes constitutes acceptance of the revised policy.
