Power Grid Operator Exam Prep · iPhone, iPad & Mac

Privacy Policy

Power Grid Operator Exam Prep (shown as “Grid Prep”, formerly System Operator Prep) does not collect any personal information. There is no account, no analytics, and no developer server. The only network traffic is Apple's: the App Store for the optional Full Access purchase and, if you leave iCloud sync on, your own iCloud account carrying your progress between your devices.

What the app collects

Nothing. Power Grid Operator Exam Prep contains no analytics, no advertising, no tracking technologies, and no third-party SDKs. It does not ask for your name, email address, employer, or any other personal detail, because it has nowhere to send them.

What the app stores, and where

The app saves your study data so your progress survives between sessions. This includes:

• which questions you have answered and whether you answered them correctly,
• the spaced-review schedule built from those answers,
• your mock paper scores and timings, your control-room simulator runs, and which credential you have selected.

All of it is written to files inside the app's own storage on your device — on a Mac, inside the app's sandbox container. It is never sent to any server belonging to the developer, and the developer cannot see it.

iCloud sync

With iCloud sync on (Library › Sync, on unless you turn it off), each of your devices also keeps a copy of its own progress in the private database of your iCloud account, through Apple's CloudKit, so your iPhone, iPad and Mac can combine their progress. Only devices signed in to your Apple Account can read that copy; the developer has no access to it, and it counts towards your own iCloud storage (a few tens of kilobytes per device). Turn sync off in the Library to keep progress on one device only. To delete the iCloud copy, use Settings › your name › iCloud › Storage › Grid Prep on an iPhone or iPad.

You can erase your progress at any time with "Reset all progress" in the Library tab — with sync on, on every device signed in to your iCloud account. Deleting the app deletes the copy on that device.

Network access

The app itself contacts no server belonging to the developer. Every question, reference card and explanation is bundled inside the app, the one-line diagrams, contingency analysis reports, AGC control boards and calculation drills are generated on the device, and everything works entirely offline. There is no server component.

The optional Full Access purchase is handled entirely by Apple through the App Store (StoreKit): Apple processes the payment and tells the app on your device whether the purchase exists. The developer receives no personal or payment information, and the app keeps only a count of the free questions, mock papers and simulator runs used, on your device and, with iCloud sync on, in your iCloud account, so the free allowance is shared by your devices.

Children

Power Grid Operator Exam Prep is a study aid for grid control-room operators and is rated 4+. Since it collects no data from anyone, it collects no data from children.
