About this policy
This policy covers SmartCalculator by RookDevStudio, including its calculator tools, offline maths assistant and advertising. It describes the current version without cloud AI or API key settings.
Information stored on your device
The app stores calculation history and favourites, recent tool inputs, preferences and settings locally. Where enabled, local app-lock settings are also stored on the device. Maths assistant inputs are processed locally; saved assistant results can appear in history. The current assistant does not send your questions to a cloud AI provider. Previously saved cloud API credentials are removed when the updated app loads settings.
Google AdMob and consent
Google’s advertising SDK processes device and advertising identifiers, IP addresses (which can indicate approximate location), app/ad interactions and diagnostic information for ad delivery, measurement and fraud prevention. Data handling depends on SDK settings and your available consent choices. The app does not intentionally send your calculation history or maths questions as ad-request content. See Google’s Privacy Policy and Google’s Mobile Ads data disclosure.
Your advertising choices
Where available, use Settings → Ad privacy choices to review advertising consent. Android settings also provide advertising ID controls. Internet connectivity is checked to manage ad loading. Without a loaded ad, the app uses its normal layout; basic calculations work offline.
Support and sharing you initiate
If you email support, we receive your email address and the information you include and use it to respond. Do not send passwords or sensitive financial details. If you choose to share content or open an external link, the selected app or website handles that information under its own policy.
Device permissions and security
The Android app uses internet and network-state access for advertising and connectivity, and may use vibration for haptic feedback. Its calculator features do not require contacts, photos, microphone or precise GPS location. Protect your device and any backups. No storage or transmission system can guarantee absolute security.
Retention and deletion
Local information remains until you delete it in the app, clear app storage or uninstall; device backups may retain or restore information according to your device settings. The current app has no developer-hosted user account to delete. For information you sent to support, contact us to request access, correction or deletion; limited records may be retained where necessary to resolve a request or meet legal obligations. Google controls retention of information processed by its advertising services under its policies.
Privacy rights and international processing
Depending on where you live, you may have rights to access, correct, delete or restrict processing of personal information, withdraw consent or complain to your local privacy authority. Contact us for information we hold; use Google’s controls for Google-managed advertising information. Service providers may process information in countries other than yours under their applicable policies and safeguards.
Younger users
Parents and guardians should supervise use where appropriate. If you believe a child has sent personal information to our support team without appropriate permission, contact us so we can review and address it.
Changes and contact
We may update this policy when features or data practices change. Material changes will be communicated through an appropriate app or website notice. For privacy questions, contact RookDevStudio at smartcalculatorapp@gmail.com.
