Bascule kiren

J’ai été basculé sans prévenance sur kiren. Le logiciel est en anglais. Donc je ne peux pas l’utiliser ou même comprendre son fonctionnement. Je ne suis même pas certain que c’est un développement de f-secure mobile. Bien sûr après le prélèvement de mon abonnement !! Je comprends mal l’aspect commercial de ce changement ? Sans réponse je changerais de fournisseur

iOSアップデート

以前のバージョンでは、iOSのアップデートに伴い、「古いバージョンのOSです。iOSをアップデートして下さい」とのアラートが表示され、アプリアイコンにバッジ表示にて、通知もありましたが、かなり前からアラートも通知もなくなりました。

iOSのアップデートも感知していない様です。

また、アプリ起動にも時間がかかり、インストールはして、随時最新バージョンにアップデートしてはいるものの、メリットが見出せない様になりました。

追記(2026.1.31) しかしながら、公開Wi-Fiネットワークに接続した際に、そのネットワークの危険性を通知して、接続を遮断してくれました。VPNを通した接続でしたが、セキュリティの高さには驚きました。

再追記(2026.9.10)最近のアップデートにより、再びiOSのアップデートを通知して来る様になりました。

アプリ内に「このアプリはKiren by F-Secureに新しい名前が変わる。」との通知(原文英文)が来ています。今はまだベータ版段階との事。詳細情報が待たれます。

(再々追記2026.10.1)Kirenにアップデートしましたが、日本語対応していません。早く日本語対応お願い致します!

(追記2026.10.30) 最新のバージョンにアップデートしました。言語選択が可能になり、日本語対応もして頂けました。ありがとうございます!

Response from developer

日本語に対応していないことで、ご不便をおかけして申し訳ございません。長くご利用いただき、また詳しいご意見をお寄せいただきありがとうございます。日本語対応についてのご要望は、担当チームへ共有させていただきます。

Français ?

Il me semble que l’ancienne application Fsecureétait en français.
En tout cas c’est infiniment plus pratique d’avoir une version française quand on ne maîtrise pas correctement l’anglais

Response from developer

Bonjour, nous comprenons votre déception. Il est en effet beaucoup plus pratique d’utiliser une application dans sa langue maternelle. Nous sommes désolés que le français ne soit pas disponible dans la nouvelle application Kiren. Nous transmettrons vos commentaires à notre équipe. Merci de votre compréhension. Cordialement, Chameni, F-Secure

Not worth the money

Seems to work ok on iPhone but complete waste of time on iPad especially messages where they can’t even get their instructions to coincide with those on iPad messages app. Their support team is hopeless too.
