Privacy

The short version

Reading this site sets no cookies and creates no record of you. There is no cookie banner because there are no cookies to ask about. If you send feedback, we receive what you wrote and the email address you gave. If you sign up for updates, we keep your email address until you unsubscribe. Either can be deleted by asking.

Who is responsible

This site is run by Ido Nov as a personal project. Questions about your data, requests to see it, correct it or delete it, all go to contact@wikicompare.app, and are answered by a person rather than a process.

If you only read

No account and no cookie. Your browser keeps two display settings in local storage (how far through the introduction you are, and whether every difference is shown), and they never leave it. Analytics runs in cookieless mode: PostHog counts visits using a hash it computes on its own servers from your IP address and browser, salted with a key that is thrown away daily, so the count cannot be turned back into a person or followed from one day to the next. We record which article was opened and whether it came from cache — never what you searched for, and never the text you clicked. Vercel, which hosts the site, also counts page views without cookies, from a hash of the request that it discards daily.

Two other parties see your IP address simply because your browser talks to them: the article photographs are served by Wikimedia, and the typefaces by Google Fonts.

If you send feedback

The feedback form asks for your email address, your message and, if you like, your name. They are emailed to our inbox and kept there, not in the site's database.

If you sign up for updates

The address you give is kept in the site's database and used for one thing: an occasional email when there is news about the project. Every update carries a link to unsubscribe, and you can also ask to be removed by writing to the address above.

Why we hold it

To answer your feedback, to send the updates you asked for, and to know whether anybody is using this. Nothing here is sold, rented, or used to advertise to you, and none of it is used to build a profile of what you read.

Who processes it for us

• Vercel: hosting, and the page-view count.
• Neon: the database.
• PostHog: analytics, as described above.
• Resend: delivering feedback to our inbox.
• Google: the typefaces.
• TypeSafe: reads the Wikipedia articles to produce the comparison. It is sent the encyclopedia's text and nothing about you.
• Anthropic: writes the explanation of a difference the first time anyone points at it. It is sent the passages involved and nothing about you.

These are companies outside Israel, mostly in the United States and the EU, so using this site means your data is handled abroad.

Email

Nothing is emailed to you automatically. We write only to answer feedback you sent, or to send updates if you signed up for them. Sending feedback never puts you on the updates list, and if we ever want to write to you about anything else, we will ask first and take no for an answer.

Your rights

Under the Protection of Privacy Law you may ask to see the data held about you, to have it corrected if it is wrong, and to have it deleted. Write to contact@wikicompare.app and you will get an answer within 30 days. Providing any of this is voluntary — the only consequence of withholding an email address is that we cannot reply to you.

Wikipedia text and photographs

The article prose and the lead photographs in the columns are the work of Wikipedia's contributors, excerpted and abridged for comparison rather than reproduced whole, and reused under CC BY-SA 4.0, which this site and anything drawn from it carry too. Each column links the exact revision it was read from, and each photograph names its author and licence.

If a comparison is wrong about you

Comparisons and their explanations are produced by language models from the articles, so they can be wrong or incomplete, and a marked difference is a pointer to check the sources rather than a finding. If one says something false about you, write to contact@wikicompare.app and the comparison comes down while it is looked at.

Changes

If this notice changes in a way that matters, the date at the top changes with it.
