Privacy Policy

Effective 7 September 2026

These practice-exam apps do not collect your data. There is no account, no server, and no backend. Everything you do stays in the browser on your own device.

What we collect

Nothing. We operate no server that receives data from the app, so there is nothing for us to collect, store, sell, or share. We cannot see your answers, your scores, or that you used the app at all.

What the app stores on your device

To remember where you left off, the app writes to your browser's localStorage under a key beginning qb.v1. That record holds:

This never leaves your device. It is not transmitted anywhere, and it is not synchronised between your devices or browsers.

What the app does not do

The one outside request

The page loads its typefaces from Google Fonts (fonts.googleapis.com and fonts.gstatic.com). Like any request to any website, this lets Google see your IP address and browser user-agent. Nothing about your answers or progress is included. Google's handling of that request is covered by Google's Privacy Policy. This is the only request the app makes to any outside server; every other feature works with the network switched off.

Hosting

Where the app is served over the web rather than opened as a local file, the hosting provider records standard web-server access logs (IP address, time, page requested, user-agent) as part of delivering the page. We do not use those logs to build any profile of you, and we do not combine them with anything else.

Children

These are practice materials for professional and academic certification exams. They are not directed at children under 13, and we knowingly collect no information from anyone — children included.

Your rights

Rights of access, correction, portability, and erasure apply to data a company holds about you. We hold none, so there is nothing for us to hand over or delete.

To erase everything the app has stored: open Settings → Data → Clear progress inside the app, or clear your browser's site data. That deletes it permanently. There is no copy on our side, so it cannot be recovered — and it does not need to be requested from us.

Not affiliated with any certifying body

These are independent practice questions. They are not official materials and carry no endorsement from any certification, testing, or licensing organisation. All trademarks and certification names belong to their respective owners and are used only to identify the subject matter of the practice questions. Where a question conflicts with the official materials, the official materials govern.

Changes

If this policy changes, the revised version will be posted at this address with a new effective date.
