CardEmberStudy does not collect, transmit, or share any personal information — there is no account, no sign-in, and no network communication of any kind.
CardEmberStudy is an offline flashcard app: eight bundled decks, 112 cards, and a spaced-repetition scheduler that brings each card back just before you would have forgotten it. The pages that follow describe, in plain language, what the app does and does not do with the things you type into it.
None. The app has no sign-up form, no email field, no contact import, and no questionnaire. The one piece of text you can type is an optional display name on the profile screen — you choose it, it can be anything, and it never leaves the device.
For the app to work, the following is kept in the operating system's local storage, on your phone, and nowhere else:
None of it is uploaded. Uninstalling the app removes every byte.
The app requests no runtime permissions. It does not ask for the camera, microphone, photo library, contacts, location, calendar, or notification access. The Android manifest declares INTERNET, the default for a Flutter project — but the app contains no networking code and makes no network requests, so the permission is declared but unused.
The app is fully offline. Every deck is bundled inside the binary, every calculation runs on the device, and no data is uploaded, downloaded, or synchronised. It behaves identically in aeroplane mode.
None are integrated — no analytics SDK, no crash reporting, no advertising or attribution SDK, no cloud database, and no authentication provider. The app’s dependencies are limited to open-source Flutter packages for local storage, state management, charts, and layout helpers. The share button on the profile screen hands a short sentence about your streak to your operating system’s own share sheet; nothing is shared unless you complete that action yourself.
The app is suitable for learners of any age. Because it collects no personal information, shows no advertising, and offers nothing to purchase, a child using it leaves no personal record behind. It is not directed at children under 13 in a way that would trigger COPPA obligations, and it processes no personal data within the meaning of GDPR Article 8. A parent or guardian who wants everything cleared can simply delete the app.
Your data lives on hardware you own, so you control it directly. Change or replace your display name at any time from the profile screen, change every study preference from the settings screen, and delete everything by uninstalling the app — that removes the database, the preferences, and all study history in one step. Because no personal data is ever received by us, there is nothing for us to access, export, correct, or delete on your behalf.
If anything in this policy changes, the date at the top of the page will be revised, and material changes will appear in the app's release notes.
