Nosy is a detective game. Every phone you search in Nosy is fictional: the messages, photos, notes, contacts and payments you see are story content written for the game, about invented animal characters living in the invented town of Furville. Nosy never reads your real messages, photos, contacts, calls, location or accounts, and never asks for permission to. It cannot be used to monitor a real person and is not intended for that.
Nosy is published by Benjamin Bayel (“we”). For any question or request about your data, email benjamin.bayel@gmail.com. No account, no ads, and we never sell data.
Your progress (clues found, answers, verdicts, streak, rank, stars, settings and language) is stored on your iPhone only, and in your own device backups if you use them. Daily reminders are scheduled on the device, only if you allow notifications; you can turn them off in Settings at any time. Deleting the app deletes all of it.
Each day Nosy downloads the day's case (a small file of story content and images) from our content server. Like any web download, the server and its hosting provider see your IP address and the time of the request to deliver the file. We don't use this to identify you and we keep no profile. Cases are cached on your device so they can be played offline.
Apple handles every payment through the App Store (and TestFlight during the beta), including the Nosy Pro subscriptions, free trials, renewals, cancellations and refunds. We never see your name, Apple ID or payment details. The app checks your subscription status with Apple directly on your device (StoreKit) and keeps a copy of that status on the device so Pro works offline; we run no server for purchases.
To make better cases, the Chief asks once, after the notification question, whether he may keep anonymous stats. Nothing is sent unless you say yes, and you can change your mind at any time in Settings → Anonymous stats: turning it off stops sending immediately.
If you say yes, Nosy sends usage events to Mixpanel, our analytics provider, with EU data residency (the data is stored in Mixpanel's European data center). Events describe how the game is played — for example “case opened”, “clue found”, “question answered”, “verdict submitted”, your streak length, which screen of the paywall you saw and whether a subscription was started — together with the app version, language, device type (iPhone, iPad, iPhone Duo), screen layout, iOS version and whether you are on Nosy Pro. They are tied to a random install identifier created by Nosy on your device; it is not your name, email, Apple ID, advertising identifier (IDFA) or any other device identifier, and a reinstall creates a new one. Mixpanel uses the IP address of each request to estimate an approximate location (country, region, city). Events never contain your contacts or anything from your own phone. See Mixpanel's privacy policy.
No advertising, no tracking. Nosy shows no ads, does not use the advertising identifier, does not ask to track you, does not follow you across other apps or websites, and never sells or shares your data with data brokers.
The share card you can post after a case contains only the case title, your score and rank — never anything from your own phone. Sharing happens through the iOS share sheet, under the terms of the app you share to.
Nosy is a cosy mystery game suitable for a general audience. We don't knowingly collect personal data from anyone, including children.
Anonymous statistics are processed only with your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time in Settings → Anonymous stats. Content downloads are processed on the basis of our legitimate interest in delivering and running Nosy (Art. 6(1)(f)); purchases are processed by Apple to provide what you bought. We hold no account about you. You can ask for access to, correction or deletion of your data, or object to its processing, by emailing benjamin.bayel@gmail.com; as statistics are tied only to a random install identifier, include the approximate dates and device you used so we can try to find the events concerned (deleting the app and turning stats off also ends any further collection). You also have the right to complain to your data protection authority.
We'll update this page if anything changes and note the date above.
