Cookie ポリシー

サイトを安全かつ安定して動作させるために不可欠な Cookie が存在する場合があります。これらには、スパム対策や負荷分散、言語設定などが含まれることがあります。必須 Cookie は、本サービスを正常に利用するために欠かせないものであり、個別にオフにすることは難しい場合があります。

We use Google Analytics to understand which pages are used most, how people move through the site, and where errors occur, so we can prioritise improvements. In the EEA, UK and Switzerland, analytics storage follows Google Consent Mode and the choice you make in Google’s privacy messaging prompt. Elsewhere, analytics may run under the defaults allowed for that region.

We may store small preference values, such as language choices or whether you have dismissed a notice, so that you do not have to repeat the same actions every time you visit.

We use Google AdSense to show ads that help fund this free project. AdSense may use cookies or similar technologies to deliver, personalise and measure ads. For visitors in the EEA, UK and Switzerland, Google’s certified CMP (AdSense Privacy & messaging — European regulations message) collects consent before personalized ads; Google Consent Mode keeps related storage denied until that choice is recorded. You can learn more in Google’s advertising and privacy documentation, and you can also change your browser cookie settings.

Where Google’s European regulations / privacy message is shown (EEA, UK, Switzerland), use that official prompt to accept or reject advertising and analytics consent. Most browsers also let you view, delete and block cookies under settings such as "Privacy" or "Site settings". Blocking all cookies may cause some features of the Vocal Range Test to stop working or behave unexpectedly.

各 Cookie がブラウザに保存される期間は、その役割によって異なります。短期的なセッション Cookie はブラウザを閉じると削除され、設定の保持などに使われる Cookie は、数日〜数か月程度を上限に自動的に期限切れとなるよう設定されることがあります。
