Privacy Policy

Last updated 12 September 2026

Upstreams is a Winnipeg waste-stream marketplace operated from Manitoba, Canada. This policy explains what personal information we collect, why, and what you can do about it. It is written to meet our obligations under the federal Personal Information Protection and Electronic Documents Act (PIPEDA).

Who to contact

Questions, corrections, and deletion requests go to hello@upstreams.ca. That inbox is monitored by the person who runs Upstreams, who also acts as our privacy officer.

What we collect

  • Account details. If you create an account, we store your email address and authentication records. We never see or store your password.
  • Listing details. If you list a waste stream, we store what you submit: business name, location, material type, quantity, frequency, description, and the contact details you give us for arranging pickup. This information is published on the site — treat it as public.
  • Claim requests. When you claim a listing, your message and contact details are emailed to us so we can introduce you to the business. We keep that email thread as a record of the match.
  • Smart Match queries.What you type into Smart Match is stored so we can see which materials people are looking for and improve the matching. Don’t put anything confidential into it.
  • Technical logs. Our hosting provider records IP addresses, timestamps, and requested pages for security and debugging.

Why we collect it

To run the marketplace: publishing listings, connecting businesses with people who can use their material, sending the emails that make an introduction happen, keeping the service secure, and understanding which waste streams are in demand. We do not sell personal information, and we do not use it for advertising.

Who processes it

We use a small number of service providers, and they only process information on our instructions:

  • Supabase — database and authentication.
  • Vercel — application hosting and server logs.
  • Resend — transactional email.
  • Anthropic — processes Smart Match queries to generate matches.
  • OpenStreetMap / Nominatim — converts listing addresses into map coordinates.

Some of these providers store and process data outside Canada, including in the United States. While information is in another country it is subject to that country’s laws, and may be accessible to its courts and government authorities. If that is a problem for you, contact us before creating an account or a listing.

Cookies

Upstreams sets cookies for one purpose: keeping you signed in. There are no advertising cookies, no analytics cookies, and no third-party trackers, which is why you are not reading this through a consent banner. Blocking cookies will stop you from signing in but will not otherwise affect browsing the site. If we ever add analytics, we will update this page before turning it on.

How long we keep it

Listings stay published until the business withdraws them or we retire them as stale. Account records last as long as the account. Email threads and Smart Match queries are kept while they are useful for operating the service, and we clear them out periodically.

Your rights

You can ask us what personal information we hold about you, ask us to correct it, and ask us to delete your account and listings. Email hello@upstreams.ca and we will respond within 30 days. You can withdraw consent at any time, though we may not be able to keep your listings live afterwards.

If you are not satisfied with how we have handled your information, you can complain to the Office of the Privacy Commissioner of Canada.

Security

Access to the database is restricted by row-level security rules, traffic is served over HTTPS, and only the operator has administrative access. No system is perfectly secure; if a breach creates a real risk of significant harm, we will notify affected people and the Privacy Commissioner as the law requires.

Changes

If this policy changes, the date at the top changes with it. Material changes will be announced on the site.
