NoteHunter has no accounts and never asks for your name, email or contact details. Your progress stays on your device. To find out how the app is used, fix crashes and handle subscriptions, it sends anonymous usage and purchase data to a small number of services. This page lists each one and what it receives.
Last updated 3 October 2026
Your progress, scores, streaks, XP, statistics, lesson history and settings are stored on your iPhone, iPad or Mac. They are not uploaded to us or synced through iCloud. They are included in your device backup if you back your device up, and they are deleted with the app if you remove it.
NoteHunter uses Google's Firebase Analytics to see how the app is used: which screens are opened, which games and lessons are played, how answers and sessions go, where people stop, and when the subscription screen is shown or a purchase is made. This is what tells us that a lesson is too hard or that a step in the app loses people.
With these events Firebase receives a random identifier for your installation of the app, your device model, iOS version, app version and language, and an approximate country that Google derives from your network connection. The app also records a few settings alongside them: the goal you picked during setup, your play mode and instrument, whether you subscribe, your current streak and the results of the starting-point check.
None of this includes your name, email, contacts, precise location or anything you type. The identifier is not your Apple Account and is not shared with other apps. Google processes the data under its Firebase privacy terms.
If the app crashes or freezes, a crash report is sent to Firebase Crashlytics: what went wrong, where in the code, the device model, iOS version and app version. NoteHunter also receives Apple's MetricKit diagnostics, which iOS gathers on the device about crashes, hangs and the app being closed by the system, and forwards them to Crashlytics in the same way. These reports are used only to find and fix bugs.
Payments are handled entirely by Apple. NoteHunter never sees your card or payment details.
The app also uses RevenueCat to keep a record of subscriptions. RevenueCat receives a random identifier created on your device, your purchase and renewal records, the goal and play mode you chose, the Firebase installation identifier above (so purchases can be matched to app usage), and the Apple attribution token described below. The identifier is not your name, email or Apple Account. See RevenueCat's privacy policy.
When you first open NoteHunter, it asks Apple's AdServices framework for an attribution token and sends it to Apple's attribution service, and RevenueCat does the same. If you installed NoteHunter after tapping one of our Apple Search Ads, Apple answers with the campaign, ad group and keyword involved, and the app records those numbers in its analytics. This is how we tell whether an ad is worth paying for.
This does not use your advertising identifier (IDFA), and it does not track you across other companies' apps or websites. That is why NoteHunter never shows the "Allow tracking?" prompt.
On devices that support Apple Intelligence, NoteHunter uses Apple's built-in language model for practice tips and to explain mistakes. This runs on your device and nothing leaves it.
The theory tutor (the questions you can ask about a lesson) may use Apple's Private Cloud Compute on iOS 27 and later, when Apple makes it available. In that case the lesson's text and the question you tapped are processed on Apple's servers. Apple designed Private Cloud Compute so that this data is used only to answer the request and is not stored or seen by anyone, including Apple. The tutor offers ready-made questions only, so nothing you write is ever sent.
NoteHunter is rated 4+, and many families use the Journey with children. The app collects the same anonymous data from every user, as described above, and never asks anyone for personal information. Parents who have questions, or who want data from a child's device deleted, can write to us at the address below.
NoteHunter is made by Akos Komuves (tallpoppy), an independent developer in Hungary, who is responsible for this data under the EU General Data Protection Regulation. The analytics and crash reporting above rely on our legitimate interest in keeping the app working and improving it. Purchase records are needed to provide the subscription you bought.
You can ask to see, correct or delete the data held about your installation, or object to its use, by writing to the address below. Because the data is anonymous, include the approximate date you installed the app and your device model so it can be found. Deleting the app removes everything stored on the device, and a new installation starts with new identifiers. If you think your data has been handled wrongly, you can also complain to a data protection authority. In Hungary this is the NAIH.
If this policy changes, the date above changes with it, and any change to what leaves your device will be described in the app's release notes.
