# Privacy Policy for Calxio **Last updated: May 4, 2026** This Privacy Policy describes how Calxio ("the app", "we", "us", or "our") handles information when you use our mobile application. By installing or using Calxio, you agree to the practices described below. --- ## 1. Who we are Calxio is a calculator application developed and operated by Accevate. If you have any questions about this Privacy Policy, you can contact us at: **Email:** sidreactorx@mail.com --- ## 2. Information Calxio itself collects Calxio is a simple calculator. The app **does not** require you to create an account, sign in, or provide any personal information to use it. The app stores the following **only on your device** (it is never transmitted to us or to any server we control): - **Calculation history** — the expressions and results you compute, shown in the History panel. This data lives in the app's local storage and is removed when you tap "Clear all" or uninstall the app. - **App preferences** — minor settings (e.g. last-used calculator page). We do **not** collect, store, or transmit your name, email address, contacts, location, photos, files, microphone input, or camera input. --- ## 3. Information collected by third parties (Advertising) To support free use of the app, Calxio displays advertisements served by **Google AdMob**, a service provided by Google LLC. AdMob may collect and process the following information: - **Advertising ID** (Android Advertising ID / IDFA) - **IP address** and approximate location derived from it - **Device information** — device model, operating system version, language, network type - **App usage data** — ad impressions, clicks, time spent on ads - **Cookies / similar identifiers** used by ad networks This data is used by Google and its advertising partners to: - Serve advertisements (including personalized ads, where permitted) - Measure ad performance and prevent fraud - Provide aggregated analytics to advertisers Calxio does **not** receive or store this data directly. All data collection by AdMob is governed by **Google's Privacy Policy**, available at: https://policies.google.com/privacy You can learn more about how Google uses information from apps that use its services here: https://policies.google.com/technologies/partner-sites --- ## 4. Personalized vs. non-personalized ads Calxio requests advertisements through Google AdMob. AdMob may show personalized ads based on your interests where you have provided consent through the platform's consent flows (where applicable, such as in the European Economic Area, the United Kingdom, and Switzerland under GDPR, or for residents of California under CCPA). You can manage or reset your advertising preferences at any time: - **Android:** Settings → Google → Ads → Reset advertising ID / Opt out of Ads Personalization - **AdMob opt-out:** https://adssettings.google.com --- ## 5. Permissions we request Calxio requests the following Android permissions: - **Internet (`android.permission.INTERNET`)** — required to load advertisements served by Google AdMob. - **Vibrate (`android.permission.VIBRATE`)** — used for tactile feedback when you tap calculator buttons. We do not request access to your location, contacts, storage, camera, or microphone. --- ## 6. Children's privacy Calxio is not directed to children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, please contact us at sidreactorx@mail.com and we will take appropriate steps to remove such information. In compliance with COPPA and the Google Play Families Policy, ads served in Calxio are configured to comply with the "Designed for Families" content rating where applicable. --- ## 7. Data retention - **On-device data** (calculation history, preferences) is retained until you clear it within the app or uninstall the app. - **Advertising data** collected by AdMob is retained according to Google's data retention policies. See https://policies.google.com/privacy for details. We do not maintain any servers or databases that store information about you. --- ## 8. Your rights (GDPR, CCPA, and similar) Because Calxio itself does not collect personal information, requests for access, correction, or deletion of personal data should be directed to **Google AdMob**, which handles ad-related data: - Google's Privacy Policy: https://policies.google.com/privacy - Manage Google ad settings: https://adssettings.google.com If you have a request that specifically concerns Calxio, you can email us at sidreactorx@mail.com. --- ## 9. Security While no method of transmission over the internet is 100% secure, Calxio does not transmit your personal information over the network. Advertising-related data is transmitted directly from the AdMob SDK to Google's servers using industry-standard secure connections. --- ## 10. Changes to this Privacy Policy We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. Significant changes will be communicated through the app or our store listing. Continued use of Calxio after any update constitutes acceptance of the revised policy. --- ## 11.
