Privacy policy
The short version
- Images you open in KBfit are processed inside your browser. They are not uploaded to us.
- There is no account, no image storage, and no tracking cookie set by KBfit.
- The site is served by Cloudflare, which processes standard request data to deliver pages and protect against abuse.
- One feature — “Download all as ZIP” — loads a compression library from a public CDN. That request contains no image data.
Your images
When you select a file, the page reads it locally and draws it into an HTML canvas. The compression, cropping, and re-encoding all happen in your browser's memory. No request containing the image or its pixel data is made to this site or to any third party.
We recommend verifying this yourself rather than taking our word for it: open developer tools → Network and compress an image, or load the page once, enable airplane mode, and compress a photo. The tool continues to work.
The one third-party request
If you use “Download all as ZIP”, the page loads the JSZip library from cdn.jsdelivr.net. That request tells jsDelivr your IP address and browser user agent, in the same way any CDN request does. It does not contain your images. If you prefer to avoid it entirely, download each file with its individual download button instead; nothing external loads for that path.
Server logs
KBfit is served by Cloudflare Workers. Like any hosting provider, Cloudflare processes request data — such as IP address, user agent, requested URL, and timestamp — to deliver content, cache it, and defend against abuse. We do not operate an additional analytics service and do not receive or analyse individual visitor profiles.
Cookies and local storage
KBfit sets no cookies and does not write your images to local storage or session storage. The site registers a service worker that caches its own HTML, CSS, and JavaScript so the tool keeps working offline; that cache never contains your images, and clearing your browser data removes it.
Analytics
There is no analytics or tracking script on KBfit at the time of writing.
Advertising
There are no advertisements on KBfit at the time of writing. If advertising is added in the future, for example through Google AdSense, Google and its partners may set cookies or use similar technologies to serve and measure ads. This policy will be updated before any advertising goes live, and the change will be dated at the top of this page.
Children
KBfit is a general-purpose utility and is not directed at children under 13. It does not knowingly collect personal information from anyone, including children.
Your choices
You can use the core tools without any third-party request by not using the ZIP download. You can block the CDN in your browser or extensions; only the ZIP feature stops working. You can clear the service worker cache through your browser settings at any time.
Changes to this policy
If the site's data handling changes — for example if analytics or advertising is introduced — this page will be updated and the date above changed.
