Your schedule stays in the tab. Here is the whole of it.

What the page collects

Nothing. There is no analytics script, no advertising tag, no cookie, no session and no account. The page is a set of static files: HTML, one stylesheet, three scripts and self-hosted fonts. Reading the expression, matching days and working out the next runs are functions that run on what is already in the page.

Where your expression goes

Nowhere. There is no request in the page at all, and a content security policy blocks every other origin, so there is no address an expression could be sent to. The sentence, the table and the run list are produced in the tab and thrown away when it closes.

What is stored in your browser

Three values, kept in local storage so the page opens the way you left it: pikkola.cron.theme (light or dark), pikkola.cron.lang (en, ko or ja) and pikkola.cron.expr, the last expression you typed. None of them contains a name, an address or anything about your servers.

The expression is also written into the address bar as ?e= so a link can carry it. That URL is part of your history and can be in a screenshot or a pasted message; the page does not send it anywhere.

To clear the settings, open your browser's site data settings for cron.pikkola.com and delete the entry, or use a private window.

The clipboard

Copy buttons write to the clipboard through the browser's own permission, and only when you press them. The page never reads the clipboard on its own.

What the host sees

Cloudflare serves these files, and like any hosting provider it records requests to the site in its own logs: an IP address, a user agent, the file requested, the time. That record is about the page, not about your schedule, because the expression never travels. We do not add analytics on top of it and we do not read those logs.

Links that leave the page

The two cards under the studio link to Gumroad and Buy Me a Coffee. Nothing is loaded from either site until you click, and after that their own privacy notice applies. Mail to [email protected] arrives in a mailbox a person reads; we use it to answer and do not add the address to a list.

Changes

If this page changes in a way that matters, the date at the top changes with it. There is no newsletter to announce it to, so the date is the record.
