A store that looks real but never ships the order. A text that looks like it comes from your bank. A video of someone who never said those words. These are not aimed only at the careless. They are built to catch anyone, on an ordinary day, in the middle of an ordinary purchase or message.\n\nKiren is a digital safety app from F-Secure, made for exactly these moments. It helps you tell what is real from what is fake, and it keeps watch over your personal information.\n\nF-SECURE MOBILE SECURITY IS NOW KIREN\nKiren is the next version of F-Secure Mobile Security, built by the same team and completely redesigned. Your existing subscription carries over automatically. Sign in with the same email address you used before and your protection is active. There is nothing to buy again and no change in price.\n\nCHECK BEFORE YOU ACT\n• Link Checker: Confirm whether a link is safe before you open it. Shopping sites get a trust rating, useful before buying from an unfamiliar store.\n• Message Checker: Paste in a suspicious text and find out in seconds whether it shows signs of a scam.\n• Breach Check: See whether an email address has appeared in a known data breach.\n• Quick Access to find, lock or wipe your lost device. \n\nPROTECTION THAT RUNS IN THE BACKGROUND (Kiren Plus)\n• Browsing Protection: Prevent cyber-criminals from redirecting you to malicious websites while using Safari browser. Bank and shop with confidence with Safari Browser. Browsing Protection verifies that banking sites are real and rates online stores before you buy.\n• Message Protection: Filters scam texts from unknown senders out of your main inbox. Conversations with your contacts are never analyzed.\n• Personal data monitoring: Watches your email addresses, phone numbers, payment cards, and identity documents around the clock. If any of them appear in a new breach, you get an alert with full details and step-by-step guidance on what to do.\n• Scam Scanner: Upload a screenshot of a listing, an offer, or a photo and Kiren's AI checks it for scam tactics and deepfake manipulation.\n• Breach Report: Get timely alerts whenever a company, app or service you use has a data breach along with info about how to best secure your data.\n\nKEEP YOUR DEVICE IN GOOD SHAPE\n• Device Health checks that a device lock is set and that iOS is up to date, the two settings that make the biggest difference to everyday safety.\n• Recent News keeps you informed about data breaches and current scams.\n\nSEE IT WORKING\nThree screens show the whole picture. Overview gives an at-a-glance read on how well protected you are. Activity shows what has been checked and what has been caught over the past week. You shows which personal details are being watched and whether any have been exposed.\n\nBUILT WITH PRIVACY IN MIND\nSign in with your email address and a one-time code. There is no password to remember. Your browsing events and checked messages are stored locally on your device. Watched personal details are shown partly hidden in the app.\n\nFREE AND PLUS\nKiren Free includes Link Checker, Message Checker, Breach Check, Device Health, and security news. Kiren Plus adds Browsing Protection, Message Protection, personal data monitoring, and the Scam & Deepfake Scanner.\n\nKiren is made by F-Secure, protecting people online since 1988.\n\nSubscription information: If you subscribe through the app, your subscription is charged to your Apple account. It renews automatically at the end of each subscription term unless auto-renewal is turned off at least 24 hours before the end of the current term. Auto-renewal can be turned off at any time in your App Store account settings. Any unused portion of a free trial period, if offered, is forfeited when you purchase a subscription.\n\nTerms of Service: https://www.f-secure.com/en/legal/terms\nPrivacy Policy: https://www.f-secure.com/en/legal/privacy/kiren","facts":{"developer_id":425351654,"developer_url":"https://www.kiren.com","first_released":"2011-10-18T06:38:43Z","support_url":"https://www.kiren.com/support","privacy_url":"https://www.f-secure.com/en/legal/privacy/lms","website_url":"https://www.kiren.com/","app_version":"11.1.7","release_notes":"This update makes Kiren Plus setup smoother, improves reliability, and includes bug fixes and performance improvements.","rating_current_version":4.64605,"rating_count_current_version":107069,"star_counts":[3188,1368,4417,12205,85884],"genres":["Utilities","Productivity"],"languages":["EN"],"content_advisories":null,"device_families":["iphone","ipad"],"chart":null},"freshness":{"apple_read_at":"2026-10-21T00:16:13.016Z","catalog_read_at":"2026-10-19T08:04:12.214Z","reviews_checked_at":"2026-10-21T00:16:13.016Z","summary_written_at":"2026-10-14T08:55:53.711Z","placed_at":"2026-10-09T03:59:53.925Z","scored_at":"2026-10-22T00:25:13.331Z"},"editorial":{"one_liner":"Digital safety app that checks links, texts and images for scams and watches personal data for breaches.","what_is":"Kiren is a digital safety app from F-Secure that helps users tell real from fake online and monitors personal information.
