Who is responsible

The data controller for this site is Jonas Strabel, Auf dem Gewölb 12, 55291 Saulheim, Deutschland. Contact: contact@webofbelief.app. See the Impressum for full operator details.

Your answers stay in your browser

The belief check runs entirely on your device. The statements you mark as believed, rejected, unsure, or qualified are saved in your browser's local storage, on your own device, so an accidental reload doesn't lose your progress. They are never sent to any server, never stored remotely, and never associated with you. They stay only until you press “Start over”(which deletes them), or until you clear your browser's site data.

No cookies, no accounts, no fingerprinting

Web of Belief sets no cookies, requires no login, and does not fingerprint your device or browser. The only thing kept on your device is the local storage entry described above — your own in-progress answers, held purely for your convenience. It is never read by a server, never shared, and is not a tracking identifier. Because nothing identifying is stored, there is no consent banner to dismiss.

What analytics we collect

We use Vercel Web Analytics, a privacy-friendly, cookieless analytics service. It records:

• Anonymous page views — the URL path visited, approximate country, referrer, and device class (desktop / mobile). No IP address is stored and no cross-site identifier is created.
• Anonymous usage events — coarse milestones that tell us whether visitors start the check, roughly how far through it they get (which step), whether they reach the results, whether they share, and whether they create or open a comparison link. These events carry only progress — never which statements you affirmed, and never your individual answers.

This data is aggregate and cannot be traced back to an individual. We use it to understand, for example, whether the introduction is clear enough that people begin the check, or where they tend to drop off, so we can improve the experience. The legal basis is our legitimate interest (Art. 6(1)(f) GDPR) in operating and improving the site; the processing is low-impact and uses no personal identifiers.

What the share features send

The shareable badge and copyable summary are generated in your browser. They contain only counts and the structural shape of your affirmations — never your individual stances — and the image is drawn locally and never uploaded. If you choose to share, your device's own share or social features handle it from there.

The “friends compare” linkis different in one honest respect, so it's worth being precise. To let a friend compare their web against yours, your individual answers are encoded into the part of the link after the # sign(the URL fragment). Browsers never transmit that fragment to a web server, so your answers still never reach us or anyone else's server — the comparison is computed entirely inside each browser. But the link itself now carries your answers: anyone you send it to can read your web from it, and like any link it may persist in chat history or a screenshot. Only share it with people you're happy to share your answers with. Nothing is uploaded, and there is still no account, cookie, or server-side record.

Hosting

The site is hosted by Vercel Inc. As with any web host, Vercel processes standard server request data (such as IP addresses) in transit to deliver the site and protect against abuse. See Vercel's privacy policy.

Your rights

Under the GDPR you have the right to access, rectification, erasure, restriction, and objection regarding personal data about you, and to lodge a complaint with a supervisory authority. Because we store no identifying data, we usually hold nothing to act on — but you are welcome to contact us at contact@webofbelief.app with any question.

Children

Web of Belief is intended for a general adult audience and is not directed at children under 16. We knowingly collect no personal data from anyone.
