What if I delete and reinstall the app?

The lock is not stored in the app

Fold'em keeps the record of your term on the server, not in the app's own files, and that is the whole reason deleting the app achieves nothing. The row that says a term is running, when it ends, who holds the key and whether the deletion lock was on outlives the install. Sign in again with the same account and the app reads it back and puts the block up again.

If you turned the deletion lock on, this question does not arise for a while: while that restriction holds, no app on the phone can be deleted at all, and taking it off starts its own 72 hour wait that your keyholder is told about.

The rehydrate is careful about what it will accept. Only a genuinely active record puts a term back; a record that has expired or ended sends you to a fresh start instead. A record the app cannot make sense of parks you rather than waving you through, because a phone cannot tell a finished term from an unreadable one, and parking is the safer of the two mistakes.

The two things that are done again

Screen Time permission is granted per install, so a new install asks for it again. The app pick is the same story for a stricter reason: the picker hands Fold'em opaque tokens that are tied to the phone and the install that made them, and Fold'em never uploads them. Only the count of what you sealed goes to the server, which is exactly why your keyholder can see that seven apps are blocked and never which seven.

So the pick is redone by hand, and there is no version of Fold'em that could do it for you. Everything else comes back untouched: the term and its end date, the day count with no break in it, the money kept, your keyholder, and the deletion lock at its old setting.

While the pick is outstanding the app reports that on every reading, and the server holds the phone in a waiting state whose word on the pass is Checking in rather than Protected. That state is not an alarm and does not send a tamper letter, because a repair in progress is not a switched off block. It is also bounded: past a grace of 12 hours it escalates to Revoked and does alert, so a reinstall that never finishes cannot be a quiet way to sit outside the term.

Why the block does not drift after that

On every launch and every time you bring the app to the foreground, Fold'em checks two things: that Screen Time is still granted, and that the settings it applied are still on the phone. If anything has drifted while the record says a term is running, it applies the block again without asking and reports what it found in the same reading.

That repair only ever tightens. It can put a shield back, and it has no path to taking one off: releases are written by the server, and the phone applies them. A reinstall, a restore from a backup and a phone that was off for a week all end in the same place, which is the block as the server describes it.

What this does not do

It does not carry the app pick across for you, and it never will, because the tokens that name your apps are kept on the phone by Apple and are not Fold'em's to move.

It does not reach a second device. Signing in on another iPhone puts the record there, but the block on any phone is only as good as the permission and the pick on that phone.

And it is not a way to change your mind. Reinstalling does not end a term, does not start an exit, does not shorten a wait and does not remove a keyholder. Leaving early has its own route, and it goes through the exit request.
