Privacy Policy
Last updated: 29 May 2026 · BEK Service Ltd
Short version: Quack does not collect, store, or transmit your personal data. The app works fully offline. The only thing that ever uses the internet is the optional advertising SDK.
What we collect
Nothing, by us. Quack has no accounts, no login, and no servers. Your debugging sessions, notes, settings, duck skins, and purchases are stored only on your device and are never uploaded to us or anyone else.
Microphone & speech (Voice mode)
If you turn on Voice mode, the app asks for microphone permission so your device's built-in speech recognizer can transcribe what you say into text for the on-device duck flow. This audio is processed on your device and is not recorded, stored, or transmitted by us. You can use the entire app without ever granting microphone access.
Advertising
The free version of Quack shows ads via Google AdMob. The Google Mobile Ads SDK may collect and process certain data (such as advertising identifiers and usage/diagnostic data) to serve and measure ads, governed by Google's Privacy Policy and your device/consent settings.
- In regions that require it (EEA, UK, and applicable US states) we present a consent prompt (Google UMP) before serving personalized ads. Decline and you receive non-personalized ads where available.
- On iOS, we present App Tracking Transparency (ATT); ads respect your choice.
- Purchasing Remove Ads or Pro removes ads from your experience.
See Google's policies: policies.google.com/privacy and AdMob data disclosure.
Purchases
In-app purchases are processed by the Apple App Store or Google Play. We never see or store your payment details. Purchases are tied to your store account and can be restored via Restore Purchases.
Children
Quack is a general-audience developer-productivity app and is not directed to children under 13 (or the minimum age in your region).
Data deletion
Because we store none of your data, there is nothing for us to delete. To remove all on-device data, use Settings → Clear sessions, or uninstall the app.
Changes
We may update this policy; the "last updated" date will change accordingly.
