How do I get the best identification result?
Use the guided capture and take clear, well-lit photos: a close-up of a leaf, the stem, and a step-back shot of the whole plant. The more of the three you provide, the more reliable the result.
My result says "likely not knotweed" - can I be sure?
A photo check is a strong first step but not a guarantee, as young shoots or partial photos can hide knotweed. If anything still worries you, buy a one-off Confirmed Report or subscribe to iD Pro to have a PCA CSJK accredited surveyor confirm it, or arrange a professional survey.
How do I restore my iD Pro purchase?
Open Settings → Restore purchases in the app, signed in to the same account you bought it with - your Apple ID on iPhone and iPad, or your Google Account on Android. Your iD Pro access will be re-applied.
How do I delete my data?
Go to Settings → Delete my data. This permanently clears your checks, photos, maps and reports from your device and erases any iD Pro cases from our servers.
I'm not receiving notifications
Check that notifications are enabled for KnotweediD in your device settings - Settings → Notifications → KnotweediD on iPhone and iPad, or Settings → Apps → KnotweediD → Notifications on Android. Verdict alerts are sent once a surveyor completes your review.
How long does an expert review take?
Whether you use a one-off Confirmed Report or iD Pro, a PCA CSJK accredited surveyor usually reviews submitted cases within 24 hours. You'll get a notification the moment your verdict is ready.
