Privacy Policy
Last updated: 2026-04-19
This notice explains how CATaxTools ("we", "us", "the site") handles personal information. It is written to meet the requirements of the federal Personal Information Protection and Electronic Documents Act (PIPEDA) and to provide additional rights for residents of Quebec (under Law 25), Alberta, British Columbia, and other Canadian provinces with privacy statutes.
1. What we collect
- Calculator inputs — income, province, deductions, etc. These never leave your browser. They are stored in the URL (so results can be shared) and may be persisted in
localStorageon your device. We do not receive, transmit, or log them on any server. - Analytics — Google Analytics 4 collects anonymised usage data (pages viewed, referrer, device type, country/province from IP, session duration). See section 3.
- Advertising — Google AdSense may set cookies to deliver and measure ads. See section 4.
- Server logs — our host (Cloudflare Pages) logs request metadata (IP, user-agent, referer, timestamp) for up to 30 days for abuse prevention and debugging.
2. Consent and controls
We do not operate a cookie banner, and Google Consent Mode is not implemented on this site: analytics and advertising cookies are set as soon as you arrive, not after any acceptance step. If you are in the European Economic Area or the United Kingdom, Google AdSense's own consent message — a setting in the AdSense console, not something we control in code — may ask you to accept or reject personalised advertising; see section 4. Everywhere else, the control that governs what is stored on your device is your browser's cookie settings.
3. Google Analytics 4
We use Google Analytics 4 (property G-0HZ03WXGSH) to understand aggregate usage. Analytics
cookies load on your first pageview, with no prior acceptance step. IP addresses are truncated by Google before logging. GA4 data
retention is set to the minimum available (2 months event, 14 months user-level). We do not
cross-reference analytics data with any named individual. Google's processing is governed by its
Privacy Policy.
4. Google AdSense
We use Google AdSense (publisher ID ca-pub-8777600112471606) to serve ads. AdSense uses
cookies and similar technologies to serve ads based on prior visits to this and other websites.
Whether ads are personalised depends on your region and Google's own consent settings (see
section 2) — we do not implement Google Consent Mode on this site.
Opt out of personalised Google ads at adssettings.google.com. Opt out of other participating advertisers via the Digital Advertising Alliance of Canada AdChoices program.
5. Cookies
A full list of cookies — name, provider, purpose, and duration — is on our Cookie Policy page.
6. Your rights under PIPEDA
Under PIPEDA, you have the right to access the personal information we hold about you, to request correction of inaccurate information, and to withdraw consent for collection or use. Given that financial calculator inputs never leave your browser, and that analytics and advertising cookies can be controlled at any time through your browser settings, much of the exercise of these rights is self-service.
You can lodge a complaint with the Office of the Privacy Commissioner of Canada (priv.gc.ca, 1-800-282-1376).
7. Quebec (Law 25)
Residents of Quebec have additional rights under An Act respecting the protection of personal information in the private sector (as amended by Law 25): to access and transfer personal information in a structured format, to request cessation of dissemination, to the right to be forgotten in certain circumstances, and to be notified of significant confidentiality incidents. You can exercise these rights, for the categories that apply online, by controlling cookies through your browser settings; Google, as the processor for GA4 and AdSense, provides further self-service at myactivity.google.com.
Complaints in Quebec go to the Commission d'accès à l'information (cai.gouv.qc.ca).
8. Alberta & British Columbia
Residents of Alberta (PIPA) and British Columbia (PIPA BC) have rights similar to PIPEDA, with complaints handled by the Office of the Information and Privacy Commissioner of Alberta (oipc.ab.ca) or the Office of the Information and Privacy Commissioner for British Columbia (oipc.bc.ca).
9. International transfers
Analytics and advertising data are processed by Google primarily in the United States. Where required, Google relies on standard contractual clauses for cross-border transfers.
10. Children
CATaxTools is not directed at children under 13. We do not knowingly collect information from children.
11. Changes to this policy
We may update this policy to reflect changes in our practices, hosting, or applicable law. The "Last updated" date at the top indicates the most recent revision.
