Short links that don't sell you to anyone.

A walking tour of every cookie we set, every analytics call we make, and every audience network we said no to.

BlinkLink is a small business and we'd like to stay that way. Selling user data wouldn't suit either our values or our balance sheet (data brokers don't actually pay much for hobby-shortener traffic; it's an unflattering market we'd rather not be in).

What we set in your browser

• A Supabase session token, so you stay signed in.
• A Dodo Payments cookie during checkout, set by Dodo Payments, not us. Cleared when you leave the checkout flow.
• A few in-page preferences in localStorage: your cookie-banner choice, dashboard sidebar state.
• If, and only if, you accept the cookie banner: Vercel Analytics, which is cookie-less aggregated page-view counting.

What we deliberately don't use

• Google Analytics. Meta pixel. Hotjar. Mixpanel. PostHog.
• Advertising networks. Retargeting pixels (you can add your own to your links, but we don't add any to the marketing site).
• Email marketing tools that track opens via tracking pixels.
• Any kind of "identity graph" or third-party fingerprinting.

Why this is the right move for a link shortener specifically

Every short link is, by construction, a place where one party trusts another with the destination of a redirect. The whole product hinges on that trust. Selling click data, or being a place that could plausibly sell click data, would ruin the entire premise.

Our privacy policy is also more thorough than most pieces of writing on this site, which we know is not a low bar. Read it if you like that sort of thing.
