Privacy

TreadRelay is a listings board. It collects as little as it can, sells nothing to anyone, and will delete what it holds about you on request.

What is collected, and why

WhatWhyKept
Your name and contact details, if you post a listingSo buyers can reach you. This is the entire point of a listing, and it is shown publiclyUntil the listing is removed
Your email, if you ask for it, when postingTo send you the link that lets you edit or remove your listingUntil the listing is removed
Your email, if you ask to be told when a size appearsTo send that one notification. Nothing else is ever sentUntil you unsubscribe
The town you type when posting or searchingTo show distances. Resolved to a town centre, never an addressTown names are cached; they identify nobody
A scrambled version of your IP addressTo stop one person flooding the site with listings. It is a one-way hash — the address itself is never storedRolling 24 hours

What is never done

Why we are allowed to hold it

For listings and alerts, because you asked us to — consent, which you can withdraw at any time. For the scrambled IP addresses, because a site that anyone can post to without an account needs some defence against abuse, and a one-way hash is the least identifying thing that works.

Who else can see it

Three suppliers process data on our behalf, and none of them use it for anything else: Vercel runs the website, Supabase stores the listings and photos, and Resend delivers email. Town names are resolved using OpenStreetMap, which receives the place name and nothing about you.

Anything you put in a listing is public on purpose, including your contact details. Contact details are only shown after a visitor taps to reveal them, which stops most automated harvesting, but a listing is a public advertisement — do not put anything in it you would not put on a noticeboard.

Your rights

You can ask for a copy of what is held about you, ask for it corrected, or ask for it deleted. If you are in the UK or EU you also have the right to object, to restrict processing, and to complain to your data protection authority.

Most of it you can do yourself: the manage link on your listing edits or removes it, and every alert email has a one-click unsubscribe. For anything else, email listings@treadrelay.com and it will be dealt with within 30 days.

If you lose your manage link we cannot recover it — only a scrambled copy is stored, deliberately. Email us and the listing will be removed once we can reasonably tell it is yours.

Where it is stored

Listings are held in Canada. Email is delivered through servers in the United States. If you are in the UK or EU, that means your data leaves your region.

Children

This site is not intended for anyone under 16.
