Privacy Policy

Last updated: March 26, 2026

1. Introduction

CanTaxPro ("we," "our," or "us") is a software-as-a-service platform designed for Canadian tax professionals and accounting firms. This Privacy Policy explains how we collect, use, disclose, and safeguard personal information when you use our platform, including our website at cantaxpro.net and all associated services (collectively, the "Service").

We are committed to protecting your privacy in accordance with the Personal Information Protection and Electronic Documents Act (PIPEDA) and applicable provincial privacy legislation. By using the Service, you consent to the practices described in this policy.

2. Information We Collect

2.1 Account & Professional Information

  • Name, email address, and password (hashed)
  • Firm or practice name, province of operation
  • Billing information (processed by Stripe; we do not store full card numbers)
  • Two-factor authentication credentials (TOTP)

2.2 Client Data (Processed on Your Behalf)

Tax professionals use CanTaxPro to manage data about their clients. This data is processed by us as a data processor on behalf of the tax professional (the data controller). It may include:

  • Client names, contact details, and addresses
  • Social Insurance Numbers (SIN) — stored encrypted using AES-256 (Fernet)
  • Tax documents (T1, T2, T4, T5, GST/HST returns, etc.) uploaded as files
  • Financial data synced from QuickBooks Online via authorized OAuth connection
  • Filing deadlines, notes, and correspondence records

2.3 Automatically Collected Data

  • Log data: IP addresses, browser type, pages visited, timestamps
  • Device information: operating system, screen resolution
  • Cookies and local storage for session management and theme preferences

3. How We Use Your Information

  • To provide, operate, and improve the Service
  • To authenticate users and maintain session security
  • To process subscription billing and send transactional emails
  • To generate AI-assisted tax analysis using large language models (data is transmitted to Anthropic's API; see Section 5)
  • To send deadline reminders and system notifications
  • To respond to support requests and service inquiries
  • To comply with legal obligations under Canadian federal and provincial law

We do not sell, rent, or share personal information with third parties for marketing purposes.

4. Data Storage & Residency

All primary data — including client records, uploaded documents, and database backups — is stored on Amazon Web Services infrastructure located in the Canada (Montreal) — ca-central-1 region. Uploaded documents are stored in Amazon S3; the application database runs on Amazon RDS PostgreSQL; document embeddings are stored in a local ChromaDB instance within the same environment.

Documents are retained for 7 years from the date of upload in accordance with standard Canadian tax record-keeping requirements, after which they are automatically archived to Amazon S3 Glacier and then purged. Deleted client records are permanently wiped (including encrypted SINs and all associated documents) within 30 daysof deletion in accordance with PIPEDA.

5. Third-Party Services

5.1 Anthropic (Claude AI)

CanTaxPro uses Anthropic's Claude API to power AI-assisted tax Q&A. When you submit a query, the content of your message and relevant retrieved knowledge-base context is sent to Anthropic's API. Client-identifying information is minimized in prompts. Anthropic's data practices are governed by their Privacy Policy.

5.2 Intuit QuickBooks Online

Users may optionally connect their QuickBooks Online account via OAuth 2.0. When connected, CanTaxPro accesses customer records and financial reports from QBO on the user's behalf. OAuth tokens are stored encrypted using AES-256. This integration is governed by Intuit's Privacy Statement. You may revoke access at any time from Settings → Integrations.

5.3 Amazon Web Services

Infrastructure provider. Data is stored in ca-central-1 (Montreal). AWS is bound by standard data processing agreements.

5.4 Stripe

Payment processing for subscriptions. Stripe handles all card data; CanTaxPro does not store full card numbers. Governed by Stripe's Privacy Policy.

5.5 Amazon SES

Email delivery for transactional notifications (deadline reminders, account alerts). Emails are sent from noreply@cantaxpro.net.

6. Security

We implement industry-standard security measures including:

  • TLS 1.2+ encryption in transit (HTTPS via Let's Encrypt)
  • AES-256 encryption at rest for Social Insurance Numbers and OAuth tokens
  • Bcrypt password hashing
  • Optional time-based one-time password (TOTP) two-factor authentication
  • Role-based access controls (admin, staff)
  • No storage of plaintext sensitive credentials

While we take reasonable precautions, no system is completely secure. In the event of a data breach affecting your information, we will notify affected users in accordance with PIPEDA's mandatory breach reporting requirements.

7. Your Rights Under PIPEDA

We use essential cookies and browser local storage for session authentication and user preferences (e.g., theme selection). We do not use advertising cookies, tracking pixels, or third-party analytics beyond server-side logs. You may disable cookies in your browser, but this will prevent login from functioning.
