What we build

wiz≡r is a personal finance app that automatically tracks your real savings rate by reading transaction data from your bank accounts via Plaid. We display amounts and account names; we don't move money, we never see your bank credentials, and read-only is the only thing we can do.

  • 📱 Native iOS (SwiftUI)
  • 🤖 Native Android (Jetpack Compose)
  • 🌐 Full-featured web app at wiz3r.com
  • 🧠 Shared business logic on Kotlin Multiplatform — same code, all three platforms
  • 🇨🇦🇫🇷 Bilingual (English / French)

Why most of our code is private

The wiz≡r mobile and web apps live in private repositories under this organization. We connect to people's bank accounts (read-only, via Plaid) and we're not in a position to open-source the application code. We do plan to publish:

  • Public docs and integration guides
  • Brand and design assets
  • Anything where open-sourcing genuinely helps the community

…in dedicated repos as we go.

How we approach security

  • Bank credentials never touch our servers. All authentication is handled by Plaid (SOC 2 Type II–certified). We receive a read-only token.
  • Encryption at rest — AES-256-GCM on sensitive fields.
  • Encryption in transit — TLS 1.2 / 1.3 with HSTS.
  • Authentication — JWT (HMAC-SHA256), BCrypt-hashed passwords (cost 12), optional TOTP MFA.
  • Daily encrypted backups with offsite copies and a tested disaster-recovery procedure.
  • No money movement — wiz≡r is read-only and not classified as a Money Services Business under FINTRAC.
