Privacy Policy

Overview

CalcNow ("the App"), developed by Golden Roots, respects your privacy. This Privacy Policy explains what data the App uses, how it is used, what is shared with third parties, and your choices.

All calculations happen on your device. The App has no user accounts and Golden Roots does not run any server that receives your data.

Data on Your Device

The App stores the following only in its private storage on your device, which other apps cannot access:

• Calculation history (expressions and results), including history from the financial tools
• Stored values: memory (M), variables A–F, x, y, z, and saved matrices or vectors
• Settings such as language, theme, angle unit, display format and haptics

This data never leaves your device unless you choose to export a backup, share a result, or show your last result on the home-screen widget.

Sharing

When you tap Share, or create a QR code of a calculation, the content is passed to the app you pick through Android's share sheet. Nothing is shared without your action.

Home-Screen Widget

If you add the CalcNow widget, your most recent expression and result are shown on your home screen. Remove the widget to stop showing them.

Permissions

Microphone (optional)

The App asks for microphone access only when you tap the voice-input button to speak a calculation. Speech is converted to text by your device's speech recognition service (for example, Google), which may process audio under its own privacy policy. The App receives only the recognized text, does not record or store audio, and does not listen in the background.

Internet

Internet access is used to load advertisements, to send anonymous usage statistics and crash reports (see below), and for Google Play features such as app updates and reviews. Calculations work fully offline.

Advertising ID

The App can read your device's Advertising ID so that ads can be served and measured. You can reset or delete it in your device settings (see Advertising).

Backup and Restore

Export and import use Android's file picker. The App writes or reads only the file you choose, in the location you choose. Backups are not uploaded anywhere by the App.

In-App Purchases

CalcNow Premium removes ads and unlocks all premium themes. It is offered as a monthly or yearly subscription, or as a one-time lifetime purchase, processed by Google Play Billing. We never receive your payment details; the App only asks Google Play which Premium purchase your account owns. Subscriptions renew automatically until you cancel them in Google Play.

Advertising

The App shows advertisements using the following third-party SDK:

Some premium themes can be tried for 24 hours by watching a short video ad. Watching is always your choice.

You can opt out of personalized ads through your device's advertising settings:

• Android: Settings → Privacy → Ads → Delete advertising ID

Where required (for example, in the EEA and the UK), the App asks for your consent through Google's consent form before showing personalized ads.

For more information, see: Google Privacy Policy | How Google uses data in ads

Analytics & Crash Reports

The App uses Google Firebase Analytics and Firebase Crashlytics to learn which features are used and to fix crashes. They collect anonymous usage events (for example, which screen was opened or that a calculation was made — never the expression or its result), crash and error reports, device model and Android version, and an app-instance identifier. This data is processed by Google under the Google Privacy Policy.

You can turn both off at any time in Settings → Share usage data. When it is off, no usage statistics or crash reports are sent.

Other Online Services

Google Play Services

The App uses Google Play's in-app review and in-app update features. These are provided by Google Play, which handles them under the Google Privacy Policy. The App does not receive the content of your review.

Data Collection Summary

Listed in the same order and with the same names as the Data safety section on Google Play. "Collected" means the data leaves your device; data that stays on your phone is marked "On device only".

All data sent over the internet is encrypted in transit using HTTPS/TLS.

Data Deletion

You can delete your data in the following ways:

1. Clear History

Open the App → History → tap Clear History, or swipe a single entry to delete it.

2. Reset Settings

Open the App → Settings → Reset settings to restore the default language, theme and display.

3. Delete All Local Data

Uninstall the App, or clear its storage in Android Settings → Apps → CalcNow → Storage, to remove all history, stored values and settings. Backup files you exported stay where you saved them until you delete them.

To stop a Premium subscription, cancel it in Google Play → Payments & subscriptions → Subscriptions, or from Settings → Manage subscription in the App.

Important: We do not keep any user data on our own servers. Advertising data is handled by Google; see the Google Privacy Policy for how to manage it.

Data Security

• Your calculations and settings are kept in the App's private storage, which other apps cannot access
• Data sent to advertising and Google Play services is encrypted using HTTPS/TLS
• The App does not send your data to any server owned or operated by Golden Roots

No Account Required

Every feature of the App works without an account or any personal information.

Children's Privacy

This App is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe that your child has provided personal data through the App, please contact us so we can take appropriate action.

Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in the App or applicable laws. Any changes will be reflected on this page with an updated "Last updated" date.
