Privacy policy

This site collects as little as possible. No advertising, no third-party tracking, no profiling, no data resale. Nothing is measured until you accept it.

What is collected without your consent

Nothing. No cookie is set and no measurement script is loaded until you click "Accept" in the banner. If you decline, or ignore the banner, no analytics request is ever sent.

Netlify, the host, keeps technical server logs — IP address, browser, page requested — for security and availability purposes. This is inherent to serving a web page and is not used to build a profile.

Cookies and measurement

If you accept, Google Analytics 4 loads, operated by Google LLC. The property used by this site is G-639GRRETZ1, and it sets two first-party cookies. Legal basis: your consent, and nothing else — Law 25 s. 8.1 and GDPR art. 6(1)(a).

The purpose is narrow: knowing which pages are actually read. Google advertising signals and ad personalisation are switched off on this property.

The full inventory — every cookie, what it does, how long it lasts, what is kept in your browser without being a cookie, and how to withdraw in one click — is set out in the cookie policy. It is kept there rather than repeated here so that there is only ever one version of it.

Technical review form

The form collects only what is needed to answer: name, email, equipment and operating environment, problem description. Consent is explicit and never pre-ticked.

Submissions are processed by Netlify Forms and forwarded by email. They are used to answer your request, and never added to a marketing list without a separate opt-in.

A honeypot field blocks automated submissions. There is no captcha, so nothing is sent to a third party for verification.

Calculators

Calculations run entirely in your browser. The values you enter — areas, thicknesses, rates, product characteristics — are not transmitted as you type, are not stored on any server, and are not recorded in analytics.

One exception exists and it is deliberate: the "Share" button writes those values into the address bar, so that a link reproduces exactly the case you calculated. From that moment the values travel with the link — whoever you send it to sees them, and they appear in the host server logs when the page is opened. Nothing is written to the address bar until you click that button, and the address reported to analytics is truncated to the page path so the values are not sent to Google.

Your last entries are kept in your browser local storage so you do not lose them on refresh. A "Reset" button clears them, and also clears the address bar.

Retention

Technical review requests are kept for as long as needed to handle them and any follow-up, then deleted.

Event-level analytics data is retained by Google Analytics 4 for 14 months, then deleted automatically. That is the longest a standard property allows.

Standard aggregate reports — visit counts per page over time — are not subject to that expiry. What disappears after 14 months is the granular data behind custom explorations, not the traffic history itself.

Your rights

Under Quebec Law 25 and the GDPR, you may request access to, correction of, or deletion of your personal data, and withdraw consent at any time.

The person in charge of the protection of personal information is H. Marouazi, for 17335920 Canada Inc. Write to contact@maintenanceblueprint.com or use the contact form, stating what you are asking for. Requests are answered within 30 days, the deadline set by Law 25.

You are also entitled to lodge a complaint with the Commission d'accès à l'information du Québec, or with your national supervisory authority if you are in the European Union.

Transfers outside Quebec

Hosting (Netlify) and analytics (Google LLC) involve processing in the United States. Both are covered by the EU-US Data Privacy Framework and by the standard contractual clauses in their data processing terms.

Being straight about the limit of that: no contractual safeguard makes United States law disappear. If you decline measurement, no analytics data leaves your browser at all — which is the only guarantee that does not depend on a third party.

When this policy changes

This policy describes the site as it is built today. It is revised in the same commit as any change that affects it — a new measurement tool, a newsletter, an added third-party service — and the date at the top of this page moves with that revision.

The date is not touched for a layout change or a corrected link. A policy that is redated without a change of substance teaches the reader to ignore the date, which is the opposite of what it is for.
