Newtora Privacy Policy

Effective date: 2026-11-07

Newtora ("the app") is a free physics study app provided by DDJ B1 ("we", "us"). It solves physics problems step by step from the values you enter, converts units, lists physical constants and keeps a history of your solutions. It has no account system, no login, no subscription and no server operated by us.

Your data

The values you enter, your solution history, favorite topics and settings are stored locally on your device.

• The app itself does not upload this data, and we never receive it.
• The advertising SDK described below may collect information as explained in that section. Your solutions and entered values are not passed to the advertising SDK.
• If you use "Share" or "Copy", the solution text goes only to the app you pick through Android's share sheet, or to your clipboard.
• Android's standard app backup may include app data in your own Google account backup if you have device backup enabled; that backup is controlled by you and Google, not by us.

Permissions

• Notifications — for optional reminders (a formula of the day in the morning and a study reminder in the evening). You can decline or turn them off in the app's Settings; every feature still works.
• Run at startup / vibration — to restore the optional reminders after the phone restarts and to vibrate when one arrives, if you allow it.
• Internet / network state / advertising ID — used by the advertising SDK described below. All physics topics, formulas and calculations work offline.

Newtora does not request location, contacts, camera, microphone, phone call, SMS, calendar or photo library permissions.

Advertising and information collected automatically

The app displays advertisements provided by Google AdMob (never on the screen where you type values). Ads are limited to content rated for general audiences. To serve and measure ads and to prevent fraud, the AdMob SDK may collect and share with Google information such as your device's advertising identifier and other device identifiers, approximate location derived from your IP address, app interactions (for example ad views and taps), crash logs and diagnostics. This data is shared with Google as a third party for advertising, analytics and fraud prevention purposes. For more information see https://policies.google.com/technologies/partner-sites.

For users in the European Economic Area (EEA), the United Kingdom and other regions where required, the app presents a consent form via Google's User Messaging Platform (UMP) before personalized advertising data is used; if you decline, non-personalized ads are shown. You can change your choice from the app's Settings screen ("Ad privacy settings") and reset or limit ad personalization in your device settings.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from children.

Your rights

Your app data exists only on your device; uninstalling the app removes it. You can delete any saved solution at any time from the History tab. Depending on your region (e.g. GDPR, CCPA), you may have rights regarding data processed by the advertising SDK; you can exercise ad-related choices through the consent form and your device's ad settings.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
