Privacy Policy

What you type stays in the page

The calculators run in your browser. The numbers you enter are not posted to the server and are not stored in a database. Nothing identifies you, because there is no account, no login and no email signup.

If you use the copy-link button, your inputs are written into the address of the page you are looking at. That link is only shared if you share it, and the values are ordinary query parameters such as age, height, weight and units.

No analytics, no advertising scripts, no cookies

This site runs no analytics, no advertising networks, no tracking pixels and no social plugins today. It sets no cookies of its own. If advertising or measurement is ever added, this page and the about page will be updated first, and the change will be visible here rather than buried.

Server logs

The web server keeps standard access logs - the page requested, the time, the response code and the browser user agent - so that failures can be diagnosed and abuse rate-limited. Logs are not used to build profiles and are rotated on the server's normal schedule.

The site is served over HTTPS, so the request path between your browser and the server is encrypted.

Questions

Privacy questions and data requests go to hello@calc.idailycheck.xyz. Because no accounts and no stored measurements exist, there is usually nothing to delete - but if you believe something of yours has been captured, write in and we will check the logs.

What a shared link reveals

A permalink is the one place where your inputs leave the calculator. The copy-link button writes your age, height, weight, sex, activity level and goal into the query string of the address, so the page can be reopened with the same numbers.

That means a shared link carries those values in plain text. Anyone who receives it can read them, and any service the link passes through - a chat app, an email provider, a URL shortener - handles them as ordinary message content. The calculator never transmits them anywhere, but you might.

Your browser also keeps the addresses you visit in its own history. That history is stored on your device, under your control, and the site has no access to it. If you do not want a calculation to persist, use the calculator without copying the link, or clear the address bar afterwards.

Retention, rights and children

Because no accounts exist, there is no stored profile to export, correct or delete. The only records that exist are the server's access logs, which are rotated on the host's normal schedule and are not joined to any identifier, and the copy of the page in your own browser cache and history.

If you are in a region with data protection rights, the practical position is the same: there is no personal data held on you beyond routine server logs. A request to access or erase anything can still be sent to the address below, and it will be answered.

The site is written for adults and is not directed at children. It collects nothing that would identify a child, and it does not knowingly process data from anyone under 13.

Hosting and third parties

The site is served from a single server that the site owner operates, behind an encrypted connection. There is no content delivery network, no tag manager and no embedded widget, so the only third party that handles a request is the network carrying it and the host providing the machine.

The pages request no external fonts, scripts, images or stylesheets. You can confirm this by opening the browser developer tools and looking at the network list: every request goes to this domain.

Keeping this page accurate

If a feature is ever added that changes any of the above - a measurement script, an embedded video, an email list - this page is updated before that feature goes live, and the change is dated rather than folded in silently. The about page carries the same commitment.

Nothing here is written to be read once. It is written so that a future change to the site can be checked against it.
