Privacy Policy

Short version: your inputs never leave your browser, and the site sets no advertising cookies.

What stays on your device

The generator runs entirely in your browser. The frequency, anchor date and adjustment rule you choose are stored only in the page address (URL) so you can bookmark or share them. They are never transmitted to a server, logged, or persisted anywhere by this site. Downloads (CSV, .ics, PDF) are generated on your device.

What the site measures

The site loads one anonymous analytics script (Microsoft Clarity) to count page views and see which pages are useful. Clarity records interaction patterns — scrolls, clicks, dead clicks — without collecting form inputs (this site has no form that submits anywhere) and without advertising cookies. You can block it with any ad blocker or Do Not Track setting without losing any functionality.

Third parties

Pages link to public government sources (opm.gov, nfc.usda.gov). Following those links is governed by those sites' own policies. Hosting is by Cloudflare Pages; Cloudflare's standard security logging applies to all web traffic.

Changes

If this policy changes, the change will be described on this page with its date. Last updated: November 2026.
