Your honest network toolbox for iPhone & iPad. Nine pro-grade diagnostic tools — running entirely on your device.
Radien has no servers. Your diagnostics never touch us.
No ad networks, no analytics, no tracking libraries. At all.
No sign-up, no login, no email required to use the app.
The toolbox
Each tool connects straight from your device to the destination you choose — and shows you exactly what a client can honestly see. No made-up grades, no exploit probes.
Dual-stack ICMP latency, jitter and loss with a plain-language grade.
Compare up to four hosts side by side, live, at a glance.
Query any record type against any resolver — both directions.
See every hop to a host, with honest per-segment analysis.
Live IPv4/IPv6 math — masks, ranges, splits — with honest /31 & /32.
Honest open / closed / filtered results and an exposure read-out.
Turn any IP notation into every other — decimal, hex, binary, PTR.
Every notation, EUI-64, plus offline vendor lookup — nothing sent out.
Read a site's certificate, chain and ciphers — direct, never via a checker.
Fair pricing
Every tool is genuinely useful for free. Radien Pro unlocks the deeper analysis — with a single purchase, not a subscription.
The core of every tool stays free. Pro simply unlocks the pro-grade depth.
The important part
Effective 9 July 2026
Short version: Radien runs entirely on your device. We operate no servers, have no user accounts, and collect, store, transmit and sell nothing. There are no third-party analytics, no advertising, and no tracking of any kind. Privacy isn't a feature we bolted on — it's the whole design.
Radien has no backend. It never sends your usage, your device identifiers, or any personal information to us or to anyone else. We have no way to see how you use the app, because that information never leaves your phone.
Radien contains no analytics SDKs, no advertising networks, no crash-reporting SDKs, and no social or tracking libraries of any kind. Apple may provide us with the same anonymous, aggregated App Store statistics (such as total downloads) that every app receives — this is a standard Apple feature, contains no personal data, and Radien itself sends Apple nothing beyond what iOS does for any app.
Radien is a diagnostic tool, so of course it makes network connections. But every one of them goes directly from your device to a destination you chose — never through us:
api.ipify.org) for your internet-facing IP, only while that sheet is open. Only your IP is retrieved; nothing about you is sent.iOS only reveals the current Wi-Fi network name (SSID) to an app that has location permission. If you ask Radien to show your Wi-Fi name, it requests "While Using the App" location access for that single purpose. Your location is never stored, logged, or transmitted — it is used only, on-device, to read the Wi-Fi name, and you can decline or revoke it at any time in iOS Settings.
Radien Pro is a one-time purchase handled entirely by Apple's App Store (StoreKit). Radien never sees your name, payment details, or Apple ID — Apple simply tells the app whether the Pro unlock has been bought. There is no subscription.
Radien shows no advertising and does not use the Advertising Identifier (IDFA) or App Tracking Transparency prompts — because there is nothing to track.
Radien collects no personal data from anyone, including children.
If this policy ever changes, the updated version will be posted on this page with a new effective date.
