Hi, how can we help?

Coming from F-Secure Mobile Security?

Good news — you're getting an upgrade.

Kiren is the next step for the app you already trust. Same team, same protection — now with more built in and working harder in the background. Your subscription comes with you, your price doesn't change, and there's nothing to buy again. Just a better app, ready when you are.

Frequently Asked Questions

Getting started

Kiren is a digital safety app for iPhone and Android. It helps tell what is real from what is fake: it checks whether an online shop can be trusted before money changes hands, spots deepfakes and manipulated images used in scams, filters harmful messages, and keeps watch over personal information, raising a warning the moment any of it appears in a data breach.

No. Kiren signs in with an email address only. A 6-digit one-time code is sent to that address, and entering the code completes the sign-in. There is no password to create or remember. See Getting Started.

When a subscription has already been purchased, sign in with the email address used for the purchase. The subscription is tied to that address and will not appear when signing in with a different one. A new user can choose any email address. The only requirement is access to that inbox, because the 6-digit sign-in code is sent there.

First check that the email address used for signing in is the one used for the purchase. If the subscription is still missing, open the purchase screen for Kiren Plus and tap Restore purchases. The purchase screen comes from the payment service, and restoring links the existing purchase back to the account.

First check the junk or spam folder, as the message is sometimes delivered there. When signing in on the same phone that receives the email, and email notifications are turned on, the code often appears as a suggestion just above the keyboard, where a single tap enters it. To paste instead, copy the code from the email, return to Kiren, and tap the first number box. The full code drops into place automatically.

A timer appears on the screen. Once it finishes, it is possible to go back and enter the correct address.

Not from within the app. To move an account to a different email address, contact support at support@kiren.com.

Most features are the same, and a few differ because of what each operating system allows:

  • Device Health on Android includes a full antivirus that scans files and apps. On iOS there is no virus scanning, as Apple does not allow it; Device Health instead checks the device lock and that iOS is up to date.
  • Message Protection on iOS moves suspected scam texts into a separate folder. On Android it detects scam messages from SMS, WhatsApp, and Instagram and lists the harmful ones inside the app, leaving the messages where they are.
  • Browsing Protection works with Chrome on Android and with a Safari extension on iOS.
  • Your apps, the analysis of what installed apps can access, exists on Android only, because Apple does not allow an app to see what else is installed on an iPhone.

Finding your way around

Kiren is built around three main screens. Swipe left or right to move between them, or tap the names at the top of the screen. Overview is the home screen and gives an at-a-glance picture of protection along with security news. Activity shows what Kiren has been doing and holds the on-demand checks and background protection features. You focuses on personal information and data breaches.

The orb reflects the balance of safe and risky events over the last 24 hours. Safe activity fills it with blue segments, and risky activity adds red ones in proportion. With no events in that window, the orb is a bare ring with no glow. This is normal on a quiet day and does not mean protection is off. See the Overview article.

The two readings measure different things, and both are correct. The headline covers setup state and anything outstanding, including a data breach. The orb covers only the last 24 hours of browsing and messaging activity. A data breach found today changes the headline, but it is not a browsing or messaging event, and the orb stays calm.

No. Recent News carries general news about breaches at companies and security guidance. A breach article there does not mean the user's own details were exposed. Personal findings are reported separately, on the You screen and by email. Reading about a breach at a familiar service is a good moment to run a Breach Check on the email address used there.
