Clock of Ages

Effective

Privacy

Clock of Ages is an educational web toy for telling time through history. The app is a part of the Cruxially collection, a small, growing collection of educational web toys and puzzles. This app is built to know nothing about you, unless you subscribe to site updates, or leave a tip. Each app in the collection has its own privacy page: this one covers this site.

The short version

  • No accounts, no sign-in and no ads.
  • No cookies of its own, and nothing about you to sell or share.
  • What you solve and the finish and design you choose stay in your own browser.
  • Your email address, only if you ask for updates, and only to send them.
  • Tips, only if you leave one, are paid on Stripe’s own pages: the site never sees your card.
  • A suggestion, only if you send one, reaches the site’s inbox with nothing about who sent it.
  • The live site counts page views, without cookies.

What stays on your device

The clock reads the time, the date and your time zone from your own device, and works everything out there. Five Clocks does the same: the day’s five come from your own date, and your answers and score aren’t kept or sent anywhere. Copying the share line puts it on your clipboard, for you to paste where you like.

Your browser keeps five things in its own storage (local storage), so they’re still there when you come back: which challenges you’ve solved, the finish and the design you’ve chosen for the clock, whether you’ve earned gilt, and whether the sign-up form on What’s new is folded away (it folds by itself once you confirm your email). They’re kept under clock-of-ages-solved, clock-of-ages-finish and clock-of-ages-updates-panel, and they never leave your device. Clearing this site’s data in your browser removes them; in a private window they last only for the visit.

Email updates, only if you sign up

If you enter your email address on the What’s new page:

  • Cloudflare Turnstile first checks that the sign-up comes from a person, not a bot. It runs on that page and on What’s next only, and to do it, Cloudflare looks at technical details from your browser, under its Turnstile privacy policy.
  • The site sends one email to that address, with a button to confirm. Nothing joins the list unless that button is pressed within 48 hours. The site itself stores nothing about the sign-up, and the page the button is on doesn’t count its views.
  • Once you confirm, your address is kept on a list at Resend, the service that sends the site’s email, not by the site itself. Like any email service, Resend also keeps a short log of the emails it sends.
  • The address is used only to send updates about Clock of Ages: never shared, never sold, and never used for anything else.
  • Every update has a link to unsubscribe. It opens a page where you can leave this site’s updates, or every list the same sender keeps.
  • Email updates are for people 13 and older.

Tips, only if you leave one

If you leave a tip from the support page:

  • The payment is handled by Stripe, on Stripe’s own pages. Your card details go straight to Stripe: the site never sees or stores them. Stripe’s privacy policy covers what you enter there.
  • Stripe emails you a receipt (and another if a tip is ever refunded).
  • Stripe shows Keith D Commiskey what’s needed to look after a tip: its amount and date, the email address and name you gave Stripe, your billing country and postal code, your card’s type and last four digits (never the full number), and the fraud checks Stripe runs on every payment (such as the IP address it came from). These stay at Stripe; the site itself keeps none of them.
  • They’re used only for that tip (a question about it, or a refund), never to send you anything else: tipping doesn’t sign you up for update emails.
  • All the apps in the Cruxially collection take payments through one Stripe account, which Keith D Commiskey runs, so Stripe’s pages, your receipt (paid to Keith D Commiskey | Cruxially) and your card statement will reference Cruxially. Using one account doesn’t change what’s kept or what it’s used for: a tip on this site is looked after only as this page says.

Suggestions, only if you send one

If you send a suggestion from the What’s next page:

  • Cloudflare Turnstile checks that it comes from a person, as on the sign-up form, under its Turnstile privacy policy.
  • Your words are emailed to the site’s inbox through Resend, with nothing about who sent them: no name, email address or IP address. Like any email service, Resend keeps a short log of the emails it sends.
  • The site keeps no copy of its own and never writes them to its logs or shows them on any page. They stay in the inbox of the person who runs the site for as long as they’re useful. There’s no way to reply, so please leave out names and contact details.

“On this day”

The cases’ events come from Wikipedia’s “On this day”, but they’re kept as files on this site, one for each date of the year. When the clock’s page opens, your browser asks this site for today’s file, and nothing goes to Wikipedia. The “Read about it” link under an event opens Wikipedia’s article only when you choose it; Wikipedia then sees that visit as it would any other (including that you came from this site), under the Wikimedia Foundation’s privacy policy.

Page-view counts

The live site (clockofages.com) counts page views with Cloudflare Web Analytics, which uses no cookies, stores nothing on your device, and doesn’t follow you from site to site. The site sees only totals: which pages were viewed, roughly where from and in what kind of browser, and how quickly they loaded.

Keeping the site running

The site runs on Cloudflare. Like any web host, Cloudflare handles your IP address and browser details to deliver the pages and protect the site, under its privacy policy. To stop floods of requests, the site counts how often each IP address sends it something (a sign-up, say), a minute at a time; those counts aren’t kept.

Children

Anyone can play, at any age: playing collects nothing about anyone. The site doesn’t knowingly collect any personal information from children under 13, which is why email updates are for people 13 and older. If you think a child under 13 has signed up, write to the address below and the address will be removed.

What the site doesn’t do

No ads, no selling or sharing data, no third-party trackers or social buttons, and no AI looking at anything you do. Everything it loads comes from the site itself, apart from the page-view counter on the live site and the sign-up check on the What’s new page.

Changes

If this page changes, it will say what changed and when, and What’s new will mention it. This version takes effect on November 1, 2026. What changed: tips, what Stripe shares about one, suggestions, that your browser keeps the design you choose, and that the site is part of the Cruxially collection, whose name Stripe’s pages, receipts and card statements carry.

Who runs it

Clock of Ages is run by Keith D Commiskey. To ask about this page, or to have your address removed from the list, write to hello@clockofages.com. To stop update emails, use the unsubscribe link in any of them. See also the terms.

For questions about the Cruxially collection as a whole, write to hello@cruxially.com. Keith D Commiskey also runs KDC-info (kdcinfo.com), which is where email replies will be from.
