Maths For Kids, Castle Adventure Chess, and 50 First Foods
Maths For Kids is a maths learning app for children. Play does not require creating an account with Tripwire Tech.
Castle Adventure Chess is a chess learning app for children. Progress and parent settings stay on the device; play does not require a Tripwire Tech account.
50 First Foods is a baby first foods tracker for starting solids. Food attempts, notes, meal plans, and related entries stay on the device; tracking does not require a Tripwire Tech account.
Information you or a parent create in these apps (for example child profiles, progress, or food tracking) is stored locally on your device. We do not operate a cloud account for that content. The App does not sell personal information.
Information We Collect
Unless an app-specific policy says otherwise:
- The apps that use this page do not collect, transmit, or sell personal information to Tripwire Tech for advertising profiles.
- Information you enter is stored locally on your device (for example in an on-device database).
Local Storage
Data remains on your device unless you choose to delete the App or clear its data. The developer does not have access to on-device diary or learning progress unless you deliberately send it (for example by email for support).
Analytics, Tracking, and Advertising
Unless an app-specific policy says otherwise, apps covered by this page:
- Do not use analytics for marketing profiling
- Do not use advertising networks (unless stated in that app’s store listing or a dedicated privacy page)
- Do not use tracking technologies to follow you across other companies’ apps for advertising
- Do not share your on-device learning or journal content with third parties for their marketing
Permissions
The App only requests permissions required for its functionality. If additional permissions are added in future releases, this policy will be updated.
Children’s Privacy
Maths For Kids is designed for young learners with parent or carer guidance. We do not knowingly collect personal information from children on Tripwire Tech servers. Profile and progress data stay on the device.
Data Security
Because your data is stored only on your device by default, you are responsible for protecting access to your device.
Changes to This Policy
This Privacy Policy may be updated from time to time. Changes will be reflected by updating the “Last updated” date.
