Privacy Policy

For www.oursharedcode.com. Last updated 19 October 2026.

The short version: this site has no accounts, no sign-ups, and no database of users. Nothing you type into the tools here is sent to us or stored on a server. Three things do reach a server: the ads on some pages; a visitor counter that records which country a visit came from and nothing else; and, on the tip page only, a counter of which buttons are pressed. This page explains exactly what each one does, how to switch the ads off, and how to stay out of either counter. A tip, if you send one, is paid through another service, and what that service passes on to us is set out under Tips.

Who runs this site

OurSharedCode is an independent personal project. There is no company behind it. You can reach the operator at hello@oursharedcode.com.

What we collect directly

No personal details. There is no registration, no login, no contact form and no newsletter. We do not ask for your name, your email address, or any other personal detail, and nothing we store has a place for one. There is no conventional analytics package here either — no Google Analytics, no tracking pixels, nothing that follows you from one day to the next. Two counters of our own are the exceptions. The per-country visitor tally described under Visitor counter and map records a country code and nothing that identifies you. The tip page's counter, described under What the tip page counts, records what is pressed on that one page, under a label that changes every day and does not say who you are.

Hosting

The site is served as static files by GitHub Pages. Like any web host, GitHub receives the technical information your browser sends in order to deliver a page — including your IP address, the page requested, and your browser type — and may keep it in server logs for security and operational purposes. That processing is GitHub's, not ours, and we have no access to those logs. See the GitHub Privacy Statement.

Prompt Engineering Studio

The tool at /prompt-engineering-studio/ runs entirely inside your browser. The prompts you write, the custom blocks you create, and your saved library are held in your browser's localStorage on your own device, and files you save go to a location you choose on your own disk. None of it is transmitted to us or to anyone else — there is no server component to transmit it to. Clearing your browser storage erases it, and we cannot recover it, because we never had a copy.

Advertising cookies

Some pages on this site show ads served by Google AdSense. Pages that do not contain ad code — including /free-english-books/ — do not run any advertising script at all.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
• You may opt out of personalised advertising by visiting Google Ads Settings.
• You can opt out of a third-party vendor's use of cookies for personalised advertising at aboutads.info/choices or youronlinechoices.com.

Opting out does not remove ads; it makes them non-personalised. You can also block cookies in your browser settings, which this site will tolerate without breaking.

Visitor counter and map

The studio page at /prompt-engineering-studio/ shows a small world map with a count of visitors by country. This is our own counter, not a third-party widget, and it works like this:

• When the page loads it calls a small service we run on Cloudflare Workers at promengi-visitor-stats.oursharedcode.workers.dev. Cloudflare passes that service the two-letter country code it has already worked out for the connection — DE, BR, and so on. We add one to the tally for that country.
• Your IP address is never stored. It is not saved to the tally, not written to a database of ours, and not kept in any log we hold. The only thing recorded against a country is a number.
• So that one person reloading the page is not counted twenty times, the service computes a one-way hash of your IP address, your browser's user-agent string and the current date, mixed with a secret key we hold. The hash cannot be turned back into an IP address, it changes every day, and it is deleted automatically after 12 hours. Its only purpose is to answer "have we counted this visit already?"
• The counter sets no cookies and stores nothing on your device.
• What appears on the page is all we can see ourselves: country codes and totals. There is no list of visitors, no per-person timestamps, no record of which pages you viewed, and nothing that could single you out.
• The tally is not shared with Google or anyone else, and it is never used for advertising, ad targeting, or ad measurement.

Cloudflare necessarily handles the request itself in order to run that service, under the Cloudflare Privacy Policy. If you would rather not be counted, blocking requests to oursharedcode.workers.dev in your browser or an extension leaves the rest of the page working normally.

Tips

The page at /free-english-books/ offers four ways to leave a tip. Since 19 October 2026 the Support Author button on the home page opens a sheet with those four and a fifth, GitHub Sponsors. Tipping is voluntary and nothing on this domain is sold. Opening a card or the sheet and showing the QR code happen inside your browser, and an address you copy goes only to your own clipboard. Since 4 October 2026 the books page does count which of its buttons are pressed; that is set out under What the tip page counts. The home page's sheet counts nothing and reports nothing to us. Neither page reports an amount or whether you paid, because neither can know. What reaches us about a payment depends on the way you pay:

• Ko-fi and Buy Me a Coffee. These buttons open their sites, and you pay there, under their privacy policies and terms. They pass on to us the amount, the name you give, any message, and usually the email address you pay with. We never see your full card number.
• GitHub Sponsors (home page only). This button opens GitHub's page, and you pay there, under GitHub's terms and privacy statement. GitHub passes on to us the amount and the tier, your GitHub username unless you make the sponsorship private, and any email address or message you choose to share. We never see your full card number.
• Bitcoin Lightning. You pay from your own wallet app, through the Lightning network, to a Wallet of Satoshi account, under Wallet of Satoshi's terms. We see the amount, any comment you type in your wallet, and, only if you send the tip as a Nostr zap, your Nostr public key. A Lightning payment does not carry your name, email address or card.
• PayID (Australia). You pay from your own bank app, under your bank's terms. Like any bank transfer, it shows us the amount, the name on the account it came from, and any description you add. That stays in our bank records, which Australian tax law requires us to keep, generally for five years.

What the tip page counts

Since 4 October 2026 the page at /free-english-books/, in each of its languages, reports what is pressed on it to a small service we run on Cloudflare Workers at stats.oursharedcode.com. It is our own counter, not a third-party one. We added it to learn whether the page is used at all, and which of the four ways people reach for. It works like this:

• What the page sends. That it was opened; which of the four buttons was pressed; whether a copy button or "Open in wallet" was pressed; that a card was closed; and how long the card and the page were in view. Each report also carries the page's language, the difference between your clock and UTC (so that a time can be read as your local time), and one of four words for where you came from: the books site, another page of this site, somewhere else, or nowhere. The address you came from is never sent.
• What it never sends. An amount, a Lightning or PayID address, anything you type, or whether a payment was made. The page cannot see your wallet, your bank, or what you do on Ko-fi or Buy Me a Coffee.
• What the service adds. The two-letter country code Cloudflare has already worked out for the connection, and a visitor label: a one-way hash of your IP address, your browser's user-agent string and the current date, mixed with a secret key we hold. The hash cannot be turned back into an IP address, and it changes every day. Your IP address and user-agent string are never stored.
• The label joins this page to the books site. freeieltsbooks.net, which we also run, counts its own page views and downloads and makes the same label in the same way. For the same connection on the same day the two labels match, so we can see that a visit to the tip page came after, for example, the Polish home page, one book's page and a download. The label does not carry over to the next day, and it does not tell us who you are.
• No cookies. The counter sets no cookies and stores nothing on your device. A second, random label ties the reports of one visit together; the page makes it afresh every time it loads and keeps it only in memory, so nothing is left on your device when you close the page.
• Kept for 90 days. After 90 days both labels are deleted from every record, on both sites. What is left is a list of separate events with nothing joining them: on this date, from this country, this button was pressed.
• Only we read it. The records are not shared with Google, with the payment services, or with anyone else, and they are never used for advertising.

Cloudflare necessarily handles the request itself in order to run that service, under the Cloudflare Privacy Policy. If you would rather not be counted, blocking requests to stats.oursharedcode.com in your browser or an extension leaves the page, its cards and its copy buttons working exactly as before.

Your rights

Unless you have sent a tip, we hold nothing that tells us who you are. The visitor counter keeps only country totals, plus a short-lived hash that cannot be reversed or traced back to you and that expires within 12 hours. The tip page's counter keeps, for 90 days, the records described under What the tip page counts. They carry a daily label, not a name or an address, so we cannot look a person up in them; if you want a visit removed sooner, write to us with its date, rough time and country and we will delete the records that match. If you have sent a tip, the details listed under Tips stay in the records of the service you paid through, and a PayID tip also stays in our bank records for as long as the law requires. Write to hello@oursharedcode.com and we will tell you what we hold and remove whatever we are not required to keep. Rights you have under the GDPR, the UK GDPR, or the CCPA regarding data held by Google, GitHub, Cloudflare, Ko-fi, Buy Me a Coffee, Wallet of Satoshi or your bank should be directed to those companies.

Children

This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect any information from children.

Changes

If this policy changes, the revised version will appear at this address with a new date at the top. Material changes are described here rather than made quietly. The most recent: on 4 October 2026 the tip page began counting which of its buttons are pressed (What the tip page counts); until that day it reported nothing.
