Play Billing and public listing alignment

  • Restored Play Billing product loading in release builds so EngiCalc Pro offers are requested from Google Play.
  • Kept release builds explicitly configured for Google Play purchases while preserving test-only billing disable hooks.
  • Updated the public app page and app catalog with the current Basic, Engineering, Programmer, RPN, Matrix, Vector, Complex, graph, formula, unit conversion, export, and backup workflows.
  • Updated the privacy policy for current local history, projects, custom formulas, custom units, exports, encrypted local backup/restore, and optional EngiCalc Pro purchases.
  • Clarified that the current Android build has no developer account system, ads, analytics, cloud sync, or developer backend for normal calculator use.

Versioning and privacy alignment

  • Updated visible app versioning to 0.1.1 while keeping the Android build number above the Play internal 101021 build.

  • Prevented the Pro page from opening a broken Google Play Billing sheet when Play products are not fully verified for review.
  • Updated the public app description for the current offline all-in-one Engineering Calc workflow.
  • Aligned the privacy policy with local history, local projects, local backup/restore, exports, and optional EngiCalc Pro purchases.

EngiCalc Pro purchase readiness

Calculation accuracy and UI validation

Google Play launch preparation

  • Prepared the public Engineering Calc app page, privacy policy, and Google Play listing materials.
