Privacy Policy

Mile Supply ("we," "us") builds personalized running-gear recommendations. This policy explains what we collect, why, and what control you have over it. Mile Supply is currently in a pre-pilot stage — this policy will be revised as the product grows.

Information we collect

Runner profile and intake answers. When you build a runner profile, we collect what you tell us across up to 13 sections: your running routine (mileage, terrain, goals), race details (date, distance and surface), current shoes and wear patterns, apparel preferences and sizing (including sports bra band/cup size where applicable), fuel and hydration habits, sock and foot-care preferences, gear you carry, recovery preferences, injury and medical-consideration history, a preferred running store, ZIP code, and brand/budget preferences. Injury, body, and similar physical information is used only to generate and explain gear recommendations — never to diagnose, treat, or predict a medical condition.

Gear Locker and gear feedback. If you have an account and use the Gear Locker, we keep what you record about each item — what it is, its size, width and colour, when and where you got it, what you paid, its mileage, and when and why you retired it — and any feedback you give on it: ratings, what you liked or didn't, problem areas and notes.

Account information. If you create an account, we collect your email address and a hashed password (we never store your password in plain text). You can also sign in with a one-time magic link sent to your email instead of a password. An account is optional — the intake and recommendation engine work without one.

Messages you send us. If you use our Contact Us form, we collect the name, email address, and message you enter and email them to our team so we can reply. We don't attach your runner profile or account to the message, and a copy is kept with our outgoing email records. Because it isn't linked to your profile, it isn't part of the profile download described below; to get a copy of a message you sent, or to have it deleted, email [email protected] from the address you used.

Usage and analytics data. We use Google Analytics (GA4) to understand how visitors use the site — pages viewed, general device/browser information, and approximate location derived from IP address. Google Analytics sets its own cookies and is a separate data controller for the data it processes; see Google's Privacy Policy for how it handles that data. We also record product-level interaction events (e.g. viewing an explanation, saving or dismissing a recommendation) tied to your runner profile, so we can improve the recommendations themselves.

Session cookies. We set essential, first-party cookies to keep you signed in and to remember your in-progress runner profile between visits. These are not used for advertising and are not sold or shared with any third party.

How we use your information

We use what you tell us to generate personalized, explainable gear recommendations; to operate your account and runner profile; to understand and improve how the site and recommendations perform; and to communicate with you about your account (e.g. verifying your email, password resets). If you name a preferred running store, we keep it with your profile. We don't send your profile to any store. The intake asks whether you'd agree to share it with that store if we ever offer that; we record your answer, and nothing is sent.

Your ZIP code. Giving us a ZIP code is optional, and giving one is not consent to anything. We show it back to you on your own profile, along with the name of the postal area it belongs to — that name is looked up each time the page loads from a dataset we ship with the site, and is never stored. It never directly changes which products we recommend. Separately, you can allow us to use it to suggest the conditions you run in — we would offer suggestions based on typical weather for your area, always unticked, for you to confirm or ignore. And, separately again, you can turn on the store finder: if you do, we send the approximate location of your ZIP's postal area — never the ZIP itself, and nothing else about you — to Google Maps Platform to find running stores near you, and we keep nothing from the result. Each permission is off unless you turn it on, either can be on without the other, you can withdraw either at any time from your runner profile, and withdrawing takes effect immediately. Your ZIP code itself is never shared with anyone outside Mile Supply, and is kept with the rest of your runner profile until you delete it — at which point it goes with everything else.

What we don't do

We do not sell your personal information. We do not share your runner profile with retailers, advertisers, or data brokers. Product links we show you point to the page a product's details came from: usually the manufacturer, sometimes a review site or retailer. None are affiliate links.

Your rights and choices

You can download a full export of your runner profile and account from your results page at any time. To request correction or deletion of your data, email us at [email protected]. Deletion requests are honored by first deactivating your account, followed by permanent removal of your data, including any messages you sent through the Contact Us form.

Data retention and security

We retain your data for as long as your account is active, or until you request deletion. Backups are encrypted. Access to the admin console requires two-factor authentication, and access to our production servers requires a private key.

Children's privacy

Mile Supply is intended for users 16 years of age and older. We do not knowingly collect information from children under 16.

Changes to this policy

We'll update the effective date above whenever this policy changes, and post material changes here before they take effect.
