No. The software that reads and edits your PDF is built into the app and runs on your device. There is no server, so there is nothing to upload to and nothing to delete afterwards.

The app refuses edits it cannot make honestly. Text in a scanned page is a picture; the invisible layer under a scan exists for search and screen readers, and changing it would make the page lie. When the app refuses, it says which text and why.

Two ways, and neither is silent. Save overwrites the file you opened, after asking. Save a Copy writes somewhere new through the system’s file picker and never touches the original.

On your device, by the app, against the document itself. The password is not stored and is not sent anywhere.

Everything. Every tool is unlocked for the length of the trial and nothing is charged during it. The subscription then begins automatically when the trial ends, unless you cancel before then — that is how an App Store free trial works. Cancel in time and you are not charged; Pandaedits stops opening and editing PDFs, and your files are untouched.

In your Apple Account’s subscription settings: on iPhone, Settings › your name › Subscriptions; on Mac, App Store › your name › Account Settings › Subscriptions. The app’s Subscription screen has a Manage Subscription button that opens the same place. Deleting the app does not cancel your subscription. Cancel during the free trial and you are never charged. Cancel later and you keep access until the end of the period you already paid for.

Subscriptions are sold and billed by Apple, so refunds are decided by Apple, not by us. Ask from the app — Settings, Subscription, Request a Refund — or at reportaproblem.apple.com. Apple emails you its decision. If the refund is granted, the subscription ends and the app stops opening and editing PDFs; your files are untouched.

Open Settings ▸ Subscription and tap Restore Purchases. The App Store is asked what your Apple Account already owns.
