Tools
The log analyzer, the download picker and the VRAM calculator process everything in your browser. We checked the network behaviour of two of them with a browser test: during an analysis the log analyzer made no request at all, and the VRAM calculator in local-file mode made none while reading a file, including a 20 GB one (how we test). The calculator’s only outside request is when you paste a Hugging Face link: your browser then requests the first few megabytes of that file from huggingface.co, directly, and nothing else (F64). Share links put your inputs in the part of the address after #, which browsers do not send to servers.
Stored in your browser
These are the only things the site stores, all in your browser and none sent to us:
| kcd-theme | local storage | Your light or dark choice |
| kcd-mysetup | local storage | The "My setup" profile: operating system, graphics card and memory. Clear it with the Clear button in My setup |
| kcd-check:<page>:<list> | local storage | Which boxes you ticked in a checklist on a page |
| kcd-os | session storage | The operating-system tab you picked, until you close the tab |
| kcd-log-handoff | session storage | Carries a pasted log from a small analyzer to the full one, then deletes itself |
Clear them from your browser’s site-data settings at any time. The site works without them.
Analytics
This site loads Google Tag Manager (container GTM-5TP8K4QV) on every page. It loads the measurement tags we set up there, which record page visits and named events and may set cookies or identifiers in your browser. Your IP address is visible to Google when the script loads. Tool inputs (logs, files, commands, keys) are never put into events. You can block the script with a content blocker or your browser’s tracking protection; the site works without it. We do not yet show a consent prompt, so visitors in regions that require consent should block the script.
Hosting and logs
The site is static files, served by a hosting provider that keeps its normal request logs (address and browser name) under its own policy. We do not receive or use them to identify visitors.
Messages to hello@koboldcpp.dev are used only to reply and to fix content.
Ads (not active)
There are no ads and no ad scripts. Before any are enabled this policy will be updated and a consent banner shown where required.
Contact and changes

Frequently asked questions
Do your tools upload my files?
No. The log analyzer makes no network request while it analyses, and the VRAM calculator reads only the first few megabytes of a model file in your browser. The one outside request a tool makes is when you paste a Hugging Face link: your browser then asks huggingface.co for the file header.
Do you use cookies?
We set none ourselves; the preferences listed on this page live in your browser storage. Google Tag Manager and the measurement tags it loads can set their own cookies or identifiers.
Do you sell data?
No. Tool inputs are never sent to us. The site loads Google Tag Manager to count page visits, and we do not sell that data.
