Privacy Policy

Last updated 22 October 2026

Bible Synapse is built to know as little about you as possible. This page explains what that means in practice.

In short

• No accounts. You never sign up or log in.
• Anonymous visit counts only; no advertising or tracking. The site counts visits with Vercel Web Analytics, which sets no cookies and keeps nothing that identifies you (details below). It runs no advertising scripts and sets no cookies of its own.
• Your notes stay on your device. Highlights, notes, bookmarks, reading-plan progress and preferences are saved in your own browser. They are never sent to Bible Synapse.
• Some material is loaded from other services, which can see your IP address, as any website you visit can. They are listed below.

What is kept on your device

When you highlight a verse, write a note, add a bookmark, follow a reading plan or change a setting, the site saves it in your browser’s own storage (IndexedDB) on that device only. Nothing is uploaded. Because it lives only in your browser:

• it is not shared between your devices or browsers;
• clearing your browser’s data for the site deletes it, and it cannot be recovered by Bible Synapse;
• you can download a copy at any time with “Export backup” in My notes, and load it back, or into another browser, with “Import backup”. The backup file stays wherever you save it.

The published site may also keep a copy of its own pages and data files on your device so that it opens quickly and works offline. This holds no information about you, and clearing the site’s data removes it.

Visit counts

To see how the site is used, Bible Synapse counts visits with Vercel Web Analytics. For each page opened it records the page’s address, the address of the page that linked to it, the country, and the kind of device, browser and operating system. It sets no cookies and stores no IP address. Visits are told apart only within a single day, by a code worked out from the request that is thrown away after 24 hours and cannot be traced back to you. Only the totals are shown, and only to the site’s operator. How Vercel Web Analytics handles data.

Other services the site uses

To show some material, your browser connects directly to these services. Each can receive the usual technical details any website receives (your IP address, browser type and the address of the page that asked), under its own privacy policy:

• Vercel, the website host, which serves the site’s files, may keep standard server logs, and provides the visit counts described above. Vercel’s privacy policy.
• Google Fonts (fonts.googleapis.com, fonts.gstatic.com), for the typefaces. Google’s privacy policy.
• The HelloAO Free Use Bible API (bible.helloao.org), for Bible commentaries, when you open the Commentary tab. bible.helloao.org.
• Wikimedia Commons (commons.wikimedia.org, upload.wikimedia.org), for illustrations and photographs of archaeological finds, when they are shown. Wikimedia’s privacy policy.

Links to other websites (museums, libraries, commentaries, articles) open those websites, whose own privacy policies apply.

Searching, the maps, the timeline, the circle and arc views, “Share as an image” and everything else run in your browser, from files that come with the site.

Children

The site collects no personal information from anyone, of any age.

Your rights

Bible Synapse does not collect or hold personal data about you, so there is nothing it can show, correct or delete on request: your notes are in your own browser, under your control. For information held by the services listed above, please contact them directly. If you have a question about privacy on this site, write to info@biblesynapse.com.

Changes

If the site ever starts to collect information, or to use a new outside service, this page will be updated first, and the date at the top will change.
