MEP Toolbook Privacy Policy

Effective date: 12 June 2026

MEP Toolbook is a standalone engineering calculator app for iPhone and iPad. The app does not require an account, does not include advertising, does not use third-party tracking SDKs, and does not send calculator inputs or saved calculations to a backend server.

Data Collection

MEP Toolbook does not collect personal data.

Calculator inputs, saved calculations, preferred units, standards-profile selection, and cached subscription entitlement state are stored locally on the user's device.

Tracking

MEP Toolbook does not track users across apps or websites owned by other companies.

Purchases

MEP Toolbook offers optional Pro auto-renewable subscriptions through Apple In-App Purchase. Purchase processing, subscription status, receipts, billing, refunds, and cancellation are handled by Apple.

Local Storage

The app uses local device storage for app preferences, preferred unit system, selected standards profile, saved calculations, and cached Pro entitlement state. Deleting the app may delete local app data stored on the device.

Support

For support, use the support contact or support URL listed on the App Store product page, or visit MEP Toolbook Support.

Changes

This policy may be updated when app features, platform requirements, or legal requirements change. The App Store product page should link to the current published version.
