Information for parents and guardians about local calculations, Google services, currency requests, feedback, and sharing.
01General-purpose calculator
Canvas Calculator is not specifically directed to children and does not require registration or an identity profile. The free version contains advertising. Optional Pro removes ads and unlocks full-resolution image, PDF, and CSV exports through Google Play purchases. Applicable usage analytics, remote configuration, and crash reporting are separate from the Pro benefit. The privacy policy explains these services.
02Parents and guardians
Calculation canvases are stored locally. Help children avoid putting names, school information, contact details, or other private content into canvas names, feedback messages, or images they share. Sharing and feedback send content only through actions initiated by the user.
03Privacy choices and deletion
Applicable consent choices are presented through Google UMP and can be reopened from Settings → Ad privacy choices when required. There is no independent analytics switch. You can remove local data by deleting canvases, clearing app storage, or uninstalling. Current versions disable system backup and device-to-device app-data transfer. Copies sent to other apps, older backups, and Google Play purchase records are managed separately. Clearing data or uninstalling does not cancel a Google Play subscription. Parents and guardians can manage purchase controls in Google Play.
04Contact
If you believe a child supplied personal information to us, contact support@weibibabu.com with enough information to identify the support message. Do not send unnecessary identity documents or additional sensitive information.
