Privacy Policy
Last updated: 2026-08-14
1. What you paste never reaches us
This comes first because it is the thing that matters. The values you type or paste into any converter on this site — timestamps, dates, and everything derived from them — are processed entirely inside your own browser by JavaScript running on your device. They are not transmitted to us, not written to any server, and never received by us in any form.
This is not a promise you have to take on trust. The site is a set of static files with no backend to send data to: open your browser's developer tools, switch to the network tab, and convert a value — no request is made. The contents of the input fields live in the page's memory only and vanish when you reload or close the tab. Timestamps pulled out of production logs are often more sensitive than they look, which is exactly why the tool is built this way rather than as a server-side API.
2. Information we collect
Epochly requires no account, no sign-up and no personal information, and there is no contact form. We do not ask for your name, email address or any other identifying detail in order to use any page on this site. Where you choose to email us through the contact page, that email reaches an ordinary mailbox in the normal way and is not connected to this website.
3. Cookies and third-party advertising
This site may display third-party advertising, including Google AdSense. Third-party vendors, including Google, use cookies (such as the DoubleClick cookie) to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and/or other sites on the internet. You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of a third-party vendor's use of cookies for personalised advertising at aboutads.info. Users in the EEA and UK may also be shown a consent prompt where required by law. These advertising cookies are set by the ad vendor and are entirely separate from the converters — no value you enter is available to them.
4. Analytics
We may use privacy-friendly, cookie-free aggregate analytics (for example Cloudflare Web Analytics) to count page views and understand which pages are useful. No personally identifying information is collected, and nothing you enter into a converter — no timestamps, dates, units or results — is ever included in analytics data.
5. Local storage and cookies set by the tool
The converters set no cookies and write nothing to local storage. Settings such as the active direction, the forced unit or the chosen time zone are held in memory for the life of the page. Some pages preset those values in their own markup, which is why a landing page can open directly in millisecond mode or on the date picker without remembering anything about you.
6. Your time zone
To show local time, the page asks your browser for its resolved IANA time zone identifier and reads your device clock. Both stay on your device and are used only to render the output you are looking at. Neither is sent anywhere, and if you would rather not expose them, every UTC output on the site is computed without them.
7. Embedding this tool
The embeddable view at /embed/ behaves identically: it is the same static page, converts
in the visitor's browser, and sends nothing back. If you embed it in your own site, no data about your
visitors reaches us beyond the ordinary request for the page itself.
8. Your choices
You can block or delete cookies in your browser settings and every converter will continue to work, because none of the functionality depends on them. You are equally welcome to use the site with an ad blocker. This service is not directed at children under 13 and we do not knowingly collect information from them.
9. Results are informational
Conversions are arithmetic, and the arithmetic is tested — but the output is provided as-is for informational purposes. It is not a legal record, a compliance artefact or a substitute for the authoritative timekeeping of the system that produced your data. The assumptions the site makes, including its handling of leap seconds and daylight-saving edge cases, are set out on the about page.
10. Changes to this policy
If this policy changes, the "last updated" date above will change with it. Material changes will be reflected on this page rather than announced separately.
