What this site collects
Pixel Handbook does not collect personal data. There are no accounts, no sign-up, no analytics scripts, and this site does not set cookies.
Calculations stay in your browser
All calculations run in your own browser. The widths, heights and other numbers you type are not sent to a server and are not stored by this site.
Hosting
This site is hosted on Cloudflare. Like any web host, Cloudflare processes technical request data, such as your IP address, to deliver the pages and protect the site from abuse. See Cloudflare's privacy policy.
If you email contact@pixelhandbook.com, Cloudflare Email Routing forwards the message to the site owner's inbox. Your email address and message are used only to reply to you.
Affiliate links
The Aspect Ratio Calculator page contains one affiliate link, to Let's Enhance, an AI image upscaler. The link is marked as an affiliate link where it appears.
If you click it, Let's Enhance and FirstPromoter, the platform that runs its affiliate program, record that your visit came from this site so that a purchase can be credited to Pixel Handbook. The Let's Enhance affiliate terms state that this tracking cookie lasts 60 days. If you buy through the link, we may earn a commission. This does not change the price you pay. If another affiliate link is added to a page, this section will be updated to name that company as well.
Advertising
There are no ads on this site today. Pixel Handbook plans to show third-party ads in the future. Ad providers may use cookies or similar technologies. Before any ads are added, this page will be updated to name the ad provider and explain what it collects and how to opt out.
Changes
When this policy changes, the date at the top of this page is updated.
