Privacy and data residency

CanTaxAi is owned and operated by NDS Consulting Inc. (Kitchener, Ontario), which is responsible for the personal information handled here. The service is designed to Canadian privacy law: PIPEDA, Quebec Law 25, Alberta and BC PIPA, and the confidentiality rules of the Income Tax Act. Version 2026-08-25. Here is what that means in plain language.

Everything stays in Canada

Database, backups, logs and any AI processing run in Canadian regions. Sub-processors outside Canada are blocked by default and the current list is published here.

Built-in safeguards

Row-level access rules, masked SIN and business numbers, an immutable audit trail on every sensitive read, short idle sessions and encrypted backups with a 7-year retention clock.

AI you can audit

AI is assistive only. Personal identifiers are replaced with tokens before anything leaves the app, every AI output is badged and reviewable by a human, and you can opt out per file.

Your rights

Download your data, correct it, ask who accessed your file, withdraw AI consent, or ask us to delete what the Income Tax Act does not require us to keep.

The fine print, in plain words

What we collect and why

Account details (name, email), profile preferences, and the tax information you or your CanTaxAi Pro enter — slips, intake answers, documents and correspondence. We use it only to operate the service: preparing returns, tracking deadlines, and reminding you about them. We never sell personal information and never use taxpayer data to train AI models.

Cookies and storage

We use only what's needed to run the app: sign-in session storage, your theme and language preferences, and security tokens. No advertising or cross-site tracking cookies.

Disclosure

Taxpayer data is visible only to the people you or your practice explicitly grant access to, within your workspace. We disclose information outside that circle only when the law requires it (for example, a valid court order), and we record such events in the breach/audit register where the law allows.

Retention and deletion

Tax records are retained in line with Income Tax Act record-keeping expectations (generally six to seven years). When retention expires or you validly request deletion of data we're not required to keep, it is removed from production systems and expires from encrypted backups on their normal rotation.

Your rights, and who is in charge

The person in charge of protecting your information (Quebec Law 25) and our privacy officer is the president of NDS Consulting Inc., 7 Duke Street W, Suite 204, Kitchener, ON N2H 6N7, Canada, reachable at privacy@cantaxai.com. Signed-in users can download a copy of their information, ask for a correction, or ask us to delete it from the privacy page in their account; we answer within 30 days. Tax records are kept six years where the law requires it, and support, sign-in and diagnostic records are deleted automatically on a published schedule.

Artificial intelligence helps read documents and summarise CRA letters, always after identifiers are stripped. No decision about you is made automatically — a person reviews and files every return — and you can switch the AI help off at any time. If you are unhappy with our answer you may complain to the Office of the Privacy Commissioner of Canada, or the Commission d'accès à l'information du Québec in Quebec.
