Short version: Wick has no sign-up, named user profiles, or ads inside the app, and it never records or transmits your microphone audio. It uses randomly generated user and installation identifiers with PostHog and Google Firebase to connect product usage, app-screen session recordings, diagnostics, and notification activity from the same app user or installation. On iOS, if you allow tracking in Apple's permission prompt, Wick also uses Meta App Events to measure whether our ads lead to app opens and purchases. If you decline, Wick does not start the Meta SDK.
Information we collect
We do not ask you to create an account and we never collect your name, email, contacts, or precise location. We do not collect advertising identifiers unless you allow iOS tracking. To operate and improve the app, we collect pseudonymous usage information through PostHog and Google Firebase:
- Product events — for example that a clean was started or finished, the result outcome, which mode was chosen, and whether a purchase or restore completed. Purchase events include the product, price, and currency reported by the store. These events are linked to Wick's randomly generated user and installation identifiers.
- Session recordings — a replay of Wick's own screens during a session, so we can see where the interface is confusing. These recordings can include visible on-screen text and controls; Wick has no account, name, email, or free-text entry fields.
- Basic device and app info — device model, operating system version, app version, and randomly generated user and installation identifiers. Wick uses the same Firebase user identifier in PostHog so app activity and notification opens can be correlated; the installation identifier distinguishes devices. PostHog may derive an approximate region from your IP address.
- Crash and diagnostic reports — through Google Firebase Crashlytics, so we can find and fix crashes. These include the crash stack and device state, not personal content.
- Push notifications — if you enable Occasional Reminders in Wick's Settings, Firebase Cloud Messaging issues a device token so we can send cleaning reminders and Wick updates. When you tap a Wick notification, we record the anonymous user, installation, and notification identifiers so we can measure opens. You can opt out in Wick at any time, independently of your device's notification settings.
Microphone
Wick requests microphone access for one purpose: to measure your speaker's output before and after ejecting water, so it can show you the difference. Audio is processed live on your device and is never recorded, saved, or transmitted. It never leaves your device, and Wick keeps no audio.
Purchases
Wick offers a one-time in-app purchase to unlock premium modes. Payments are handled by Apple through the App Store or Google through Google Play. We never see or store your payment details. On Android, Wick sends the Play purchase token and the randomly generated Firebase user token to our Firebase service so it can verify the purchase with Google before unlocking the app. Apple's privacy policy and Google's privacy policy apply to their transaction processing.
For Google Play review, reviewers can enter a private access code in the Android app. Wick sends the code and anonymous Firebase user token to our Firebase service, which grants Wick Full access to that installation for up to 90 days. The code is not sent to analytics or shown in session recordings.
Third parties
Wick uses these analytics, reliability, and advertising measurement providers:
- PostHog (United States) — pseudonymous product analytics and session replay.
- Google Firebase — analytics, Crashlytics crash reporting, Remote Config, and Cloud Messaging (push). Google's privacy terms apply to data it processes.
- Meta (iOS only, after you allow tracking) — App Events for measuring installs, app opens, and App Store purchases attributed to Wick ads. Meta may receive the advertising identifier, basic device and app information, app-open events, and purchase product, price, and currency. Wick does not send its Firebase user ID, installation ID, microphone audio, or session recordings to Meta.
Only the Meta data described above is used for advertising measurement, and only after iOS tracking permission. We do not sell this data.
Data sharing
We do not sell your data. PostHog and Google Firebase handle the pseudonymous usage, crash, and messaging data described above so we can improve the app. If you allow iOS tracking, we also share the limited App Events data described above with Meta to measure our advertising. You can change tracking permission in iOS Settings at any time.
Children
Wick does not ask for a child's name, email, contacts, or precise location. The pseudonymous app-use and diagnostic data described above is collected in the same way for every user. Meta App Events is started only when iOS grants tracking permission.
Changes to this policy
If this policy changes, we'll post the updated version on this page with a new date.
