Tailor Pad

The simple way for tailors to save, organize, and reuse customer measurements.

Status: Public Beta. Distributed via APK to a small tester cohort. Play Store launch later.

A frontend-only React Native (Expo) app that stores customer measurements on the user's device. No backend, no account, no telemetry.

What It Is

• Audience: individual tailors who currently track measurements on paper.
• Core flow: create reusable measurement templates → add customers under a template → enter and edit measurements → export to PDF or share.
• Data: customer name + arbitrary measurement key/value pairs. Stored locally in AsyncStorage. Lock password stored in iOS Keychain / Android Keystore via expo-secure-store (salted SHA-256, never plaintext).
• Distribution: Android-first via APK / Play Console Internal Testing. iOS later.

Tech

• Expo SDK 54 / React Native 0.81 / React 19
• TypeScript strict mode
• expo-router (file-based routing) with typed routes
• Zustand for state, with persist middleware over AsyncStorage
• Outfit via @expo-google-fonts/outfit
• expo-secure-store for credentials, expo-crypto for hashing/random IDs, zod for backup schema validation
• expo-print + expo-sharing for PDF export, expo-document-picker + expo-file-system for backup import/export
• react-native-reanimated + react-native-gesture-handler for swipe actions and draggable lists

Local Development

npm install
npx expo start

Then press a for Android (emulator or USB-connected device with developer mode on), i for iOS simulator (macOS only), or scan the QR with Expo Go for a quick preview.

Run the same checks CI runs:

npx tsc --noEmit   # type-check
npx expo lint      # lint
npm test           # 15 unit tests

Build for Distribution

# Preview APK for beta testers
eas build --profile preview --platform android

# Production AAB / APK
eas build --profile production --platform android

See docs/HOW_TO_RELEASE.md for the full release flow, including OTA updates via eas update.

Security & Privacy

• Customer measurement data is personally identifiable under NDPA (Nigeria). The canonical privacy notice is docs/PRIVACY.md.
• See SECURITY.md for vulnerability reporting.
• See docs/security/threat-model.md for the in-scope threats and the mitigations in place.
• See docs/security/incident-response.md for what happens if something goes wrong.
