Privacy Policy
Effective date: June 23, 2026
This Privacy Policy explains how BEK Service Ltd (“we”, “us”), a company registered in the United Kingdom, handles information in connection with the Strumlux mobile app (the “App”).
The short version
- We do not require an account or sign-up.
- We do not collect personal data on our own servers — we don’t run any.
- Your practice progress and settings are stored only on your device.
- The App is free and supported by ads (Google AdMob) and an optional one-time in-app purchase.
Information stored on your device
Your practice history, stars, streaks, custom patterns and settings are saved locally on your device. They are not transmitted to us and are removed if you delete the App.
Advertising
The App shows ads through Google AdMob. To serve and measure ads, AdMob may process device identifiers and usage data in accordance with Google’s policies. In regions where it is required, you will be asked for consent before personalized ads are shown, and you can choose non-personalized ads. On iOS, the App will request permission before any tracking and works fully without it.
In-app purchases
The optional “Strumlux Pro” purchase is processed by Apple’s App Store or Google Play. We do not receive your payment details. The purchase status is stored on your device.
Permissions
The App requires no special permissions for its core features. It does not use your microphone, camera, location or contacts. A network connection is used only to load ads; the App otherwise works offline.
Children
The App is not directed to children under the age required by your local law, and we do not knowingly collect personal data from children.
Your rights
Because we hold no personal data about you, there is nothing for us to access, correct or delete on our side. To remove all locally stored data, simply uninstall the App.
Changes
We may update this policy from time to time. Material changes will be reflected on this page with a new effective date.
