Privacy notice

Effective October 18, 2026 (server logs, Cloudflare and named providers revised; previous revision October 5, 2026; first version August 29, 2026)

Who we are

Altered Horizon Ventures Inc. (Horizon Modifié), Montréal, Québec. The person in charge of the protection of personal information is the company's president. Questions and requests: [email protected].

What we collect for a check

Your email address, the civic address you check and its coordinates, your language, and the payment identifiers Stripe sends us (session and payment identifiers, never the card number). The computed result is linked to that data for as long as it is kept.

Our server also logs your IP address and browser type with each request; these logs are used for security, abuse prevention and troubleshooting, and are deleted within 15 days.

Ordering or viewing a check sets no cookies of ours. Cloudflare, which protects the site, may however set a strictly necessary security cookie (such as cf_clearance) to tell visitors from bots. The maps show a Natural Resources Canada base map loaded through our server, which passes on no cookie from that service. We use Google Analytics to measure traffic, but only if you have accepted it: nothing is loaded and no identifier is created until you click Accept, and ignoring the request counts as a refusal. If you accept, Google receives your (truncated) IP address, your browser and the pages you view, and sets its own cookies. You can withdraw below at any time.

Why

To produce and deliver the check, send you the result link, process the payment and any refund, answer your requests, and meet our legal obligations, tax records included.

How long

Your email, the address, the coordinates and the result are deleted automatically 30 days after you place the order. A copy can remain in our backups for up to 30 more days, until the backup that holds it is deleted. Only the Stripe payment identifiers and the amount are kept, without any identifying information, for accounting. Stripe keeps the receipt under its own rules.

Who processes your data

Stripe (payment, United States); Natural Resources Canada's address geolocation service (turning the address into coordinates, we keep nothing there); our host DigitalOcean (Toronto, Canada); Cloudflare (traffic routing, bot detection across the site and, when it is enabled, the Turnstile anti-robot check on the order form); Resend (sending the result emails, United States); and, only if you accept it, Google Analytics (traffic measurement, United States). Your data may be communicated to and stored outside Québec, including in the United States, with these providers to the extent the service requires.

Your rights

You may ask for access to your information, its correction or its early deletion by writing to [email protected]. You may also file a complaint with the Commission d'accès à l'information du Québec.

Security

Data travels encrypted (TLS), results are reached through a private link, and system access is limited to the people who need it. In case of a confidentiality incident presenting a risk of serious injury, we notify the Commission d'accès à l'information and the people concerned.

FloodVerity provides flood-risk screening and decision-support information. It is not a substitute for regulated flood mapping, professional engineering analysis, insurance underwriting judgment, emergency instructions, or site-specific professional advice.
