Privacy policy
The short version: your test answers never leave your browser, there are no accounts, and we do not ask for your email address.

What we collect
Exam Sensei is a static website. There is no account system, no login, no registration form and no newsletter sign-up. We do not ask you for your name, email address, phone number or any other personal detail in order to use the site.
Your test answers
When you take a mock test, your answers, your flags and your remaining time are stored in your own browser using localStorage. This is what lets you close the tab and resume an unfinished attempt later.
That data stays on your device. It is not transmitted to us, it is not stored on a server, and we have no way of seeing it. It is not shared between your devices, and clearing your browser data deletes it permanently.
The same applies to your theme preference (light or dark) and to any drafts made in the question editor.
Cookies
Exam Sensei sets no cookies of its own. Your answers, your theme preference and your editor drafts all use localStorage, which is a different mechanism and is never transmitted to a server with your requests.
Google Analytics, described below, does set its own cookies in order to recognise a returning visit. Those are the only cookies this site causes to be stored.
Analytics
We use Google Analytics 4 to understand which exam guides and mock tests people actually use, so we know what to write and fix next. It records the pages you visit, roughly where in the world you are, your device and browser type, and how you reached the site — for example from a search engine or a link.
It does not receive your name, your email address or your test answers. Your answers stay in your browser, as described above. Google Analytics 4 does not log or store full IP addresses; your IP is used to derive an approximate location and is then discarded.
Google processes this data on our behalf as our analytics provider, underGoogle's privacy policy. You can opt out entirely with Google'sbrowser opt-out add-on, or by using your browser's "Do Not Track" or tracker-blocking settings — the site works exactly the same either way.
We run no advertising scripts, we do not use Google Analytics for ad personalisation, and we do not sell or share this data with anyone else.
Hosting and server logs
The site is served by a static hosting provider. As with any website, the host's servers may automatically record standard request information — IP address, browser user agent, requested URL and timestamp — as part of delivering pages and protecting against abuse.
These logs are generated and controlled by the hosting provider under their own policies. We do not build profiles from them and do not use them to identify individuals.
Links to other sites
We link to official sources such as the JLPT site, the Japan Foundation's JFT-Basic site and Japan's Immigration Services Agency. Those sites have their own privacy policies, which govern what happens once you leave here. We have no control over them.
Children
The site is a study resource suitable for general audiences. We do not knowingly collect personal information from anyone, including children, and we ask for no names, accounts or email addresses. The only data collected is the anonymous, aggregated usage measurement described under Analytics.
Your rights
Data-protection law gives you rights to access, correct and delete personal data held about you. We hold no account, no name and no contact details for you, so in practice there is nothing for us to look up and return. The analytics data described above is aggregated and cannot be traced back to you by us; you can stop it being collected at all using the opt-out linked in that section. Everything else lives in your own browser and you can clear it yourself at any time through your browser settings.
If you email us, we will of course hold that email in order to reply to it. If you would like that correspondence deleted, ask and we will delete it.
Changes to this policy
If this policy changes, the revision date at the top of this page will change with it. Material changes — for example, introducing analytics — will be described here rather than made quietly.
