Your privacy,
in plain language.
This Privacy Policy explains how the CostMyWatt Energy Calculator Android application handles information. CostMyWatt is developed and published by CostMyWatt.
Your calculations stay on your device.
Effective date: 18 August 2026
Data collection and sharing
CostMyWatt does not collect, transmit, sell, or share personal data. Calculator inputs and results are processed on your device. The app does not require an account and does not include analytics, advertising, authentication, or crash-reporting SDKs.
Permissions and network access
The current version does not request sensitive device permissions or Internet access. Its calculators work without sending your input to a CostMyWatt server.
Local storage, retention, and deletion
The app may retain non-sensitive interface preferences using Android platform storage. CostMyWatt does not keep calculator data on its own servers. You can remove local app data at any time by clearing the app's storage or uninstalling the app. Android may back up eligible app data according to your device and Google Account backup settings.
Children
CostMyWatt is a general utility and is not directed to children. The app does not knowingly collect personal data from children.
Changes to this policy
We will update this policy before releasing a version that adds data collection, advertising, analytics, online accounts, cloud sync, or another third-party service. The effective date above will also be updated.
