Most questions have short answers. If yours isn't here, write to me directly — this is a one-person project and I read everything.

I bought "Without ADs" but the ads are still there

Open Settings inside the app and tap Restore Purchases, then relaunch. Purchases are tied to your Apple Account, so the same purchase works on every device you sign in with. On Android, Premium is restored from your Google account on launch, and Settings has a Restore purchase button too.

A tool shows no result or times out

Many networks filter ICMP and unusual packet sizes — mobile carriers especially. Try a different target host and, if you can, a different network. If a tool fails consistently on a normal Wi-Fi connection, email me the tool name and your iOS or Android version.

Does the app collect my data?

Diagnostic results stay on your device. The app uses Google AdMob for ads and Google Analytics for Firebase for aggregate usage statistics, both subject to your consent choice where consent is required. Details are in the privacy policy.

Which languages does the app support?

Thirteen: English, Arabic, Russian, Ukrainian, German, Spanish, Portuguese (Brazil), French, Italian, Polish, Japanese, Korean and Turkish — including full right-to-left layout for Arabic.

Is there an Android version?

Yes. NetDiag+ is on Google Play as a native Android app with the same measurements, not a port of the iPhone code.
