About this policy
This policy describes the app’s current local features and planned Google advertising integration. The app is not yet published in the stores. Native advertising and consent behavior still require validation in standalone builds. We will update these disclosures when the implementation changes.
Calculations and local settings
Calculations are processed on your device. We do not run a calculation backend, store calculation history, require accounts or sign-in, or operate our own analytics. Skin, motion and haptic preferences are saved locally on your device. They can be removed by clearing the app’s data or uninstalling it, subject to your device’s backup settings.
Clipboard
Copying a result happens only after you explicitly choose Copy. The app writes the selected result to the clipboard; it does not read your clipboard. Other apps and your operating system may handle clipboard content according to their own settings.
Google advertising and consent
The planned integration uses Google AdMob for ads and Google’s User Messaging Platform (UMP) for consent. We request non-personalized ads. This does not mean Google processes no personal data: Google may process network and device information, IP addresses, storage or identifiers allowed by the device configuration, diagnostics, ad interactions, and information used for security and fraud prevention.
The current app configuration does not request Apple App Tracking Transparency permission or IDFA access and does not request access to the Android advertising identifier. This does not eliminate all other data processing by Google.
Where applicable, a consent message is intended to present choices before ads are requested. Choices and any available privacy-options entry point depend on region, Google’s configuration and the final native integration. That production flow has not yet been verified. You may contact us with questions about your options.
Read Google’s Privacy Policy and how Google uses information from apps that use its services. Google determines retention for information it processes under its policies and may process information outside your country.
Offline use
Calculations work offline. Advertising, consent messages and other external services may need an internet connection. AdMob ads do not function inside the Expo Go test environment.
Purchases
All 28 skins are free. A future one-time purchase to remove ads is under consideration; purchase and restoration are not currently implemented.
Support messages and retention
If you email us, we receive your address and message, and use them to respond. Do not include sensitive information or passwords. We keep correspondence only as needed for the request and applicable obligations; our contact mailbox is provided by Google. Local app preferences remain on your device until removed. Google’s data handling and retention are governed by its policies.
Children
We do not knowingly collect children’s personal information through a developer-operated account or calculation service. A playful design is not a representation of a child-directed advertising configuration. Age targeting and store declarations must be finalized before release. If you have a concern about a child’s information, contact us.
Your privacy requests
Contact juanca05@gmail.com to ask questions or request access, correction or deletion of information you have sent us. We do not hold your calculation history or locally saved preferences. For information Google processes, consult Google’s privacy resources. Available rights depend on your location and applicable law.
Policy updates
We may revise this policy when features or service providers change. The date above shows the latest update. This policy does not certify legal compliance or replace the disclosures required by app stores.
