Privacy Policy
Last updated: October 6, 2026
Halfmark is a worksheet that runs in your web browser. This policy explains what happens to data when you use it.
Payroll data stays in your browser
Files you add (payroll registers, hours, provider totals) are read and calculated by code running in your browser tab. They are not uploaded to Halfmark, to our hosting provider or to anyone else. The app does not store payroll data in your browser's storage either: it is kept in the tab's memory and disappears when you close or reload the tab. Exports (CSV, PDF and project files) are created in your browser and saved to your device; we never receive them. Sample files offered in the app are fictional and are loaded from this website.
What this website collects
Halfmark has no accounts, no cookies, no analytics scripts and no advertising or tracking scripts. Pages don't load scripts, fonts or other resources from third-party servers. To see whether the site is useful, this website's own code on Cloudflare keeps anonymous, aggregate daily counts: pages viewed, visitors' country, the domain of the website that linked here, and how many times CSV and PDF exports are created. When you download an export, the app sends only the word “csv” or “pdf” to this website's own counter (/api/use); no payroll data, file names or amounts are sent. These counts contain no IP addresses, cookies or identifiers, and they are not shared with any third party. Our hosting provider, Cloudflare (Cloudflare Pages), processes standard technical data such as IP address, browser type and requested page addresses in order to deliver and protect the website. See Cloudflare's privacy policy: cloudflare.com/privacypolicy.
If you email us, we use your email address and message only to reply to you. Please don't send payroll files or employee information.
