The claim rules out subscriptions, purchases, ads and watermarks, and promises edits you can undo. It is silent on accounts, export and where your photos go - so check those four things yourself.

Its own listing says subscriptions cannot be cancelled during the active period, and sets two 24-hour clocks. Here is what cancel can still mean, and Apple's route for money already taken.

The same code can join a Wi-Fi network, apply a coupon or open a web page, and the app's job is to act on it, not to preview it. Read one scanner's own listing, and the six habits that survive it.

Three listings read as commercial documents: one names the studios it is allowed to carry, one says only available on Tubi about a handful of titles, and one makes your own files the catalogue - with a server that must stay running.

Two of them promise a copy you fetched; the third promises access to any file in your account. The difference is what you discover at 30,000 feet, in each app's own words.

Require purchase approval plus an account of their own is the fix - and Apple lists three things it does not cover. If the charge already happened, the route and the pending-charge trap.

Never rent or sell your data is a promise about money, not about access. Read what a keyboard app's own listing claims, and the three questions it leaves open.

Between the camera and the PDF, the app picks the page edges, merges dozens of shots into one file, offers five destinations, and quietly asks you to subscribe for backup. All in the developer's own words.

One mainstream learning app states in its own listing that it has no ads and no subscriptions, and another says plainly that it is a subscription app. Between those two sentences sit five questions worth asking any app your child wants.
