Cookieless analytics for creators

Cookieless analytics is analytics that runs without setting a browser cookie on the visitor. That is the definition, plainly stated, before the marketing gets involved. The reason it exists as a category is that cookies are the mechanism most tracking cared about for the last twenty years: a cookie stitches together page loads into a session, links repeat visits to the same visitor, and (in the third-party cookie case) follows the same person across different sites. All three uses are now regulated in the EU under GDPR and increasingly disliked by every browser vendor. Cookieless analytics drops the cookie and finds other ways to answer smaller versions of the same questions. The honest tradeoff is that some of those questions get worse answers, some get equivalent answers, and a few get better answers because the cookie was a bad tool for the job in the first place. This page covers what you actually get from cookieless analytics, what breaks, and how linksync's cookieless mode fits.

What this page covers

What cookieless analytics gives you

  • A shorter, cleaner privacy story

    No visitor cookie means most of the reasons a browser or a regulator would flag your analytics simply do not apply. First-party cookieless analytics fits well within GDPR expectations because it does not persist a per-visitor identifier or share data with third parties.

  • No cookie banner is required in most setups

    Cookie banners exist because non-strictly-necessary cookies need consent. If your analytics does not set a cookie at all, and your tracker is first-party (running on your own domain, not a third-party ad network's), most jurisdictions do not require a consent banner for it. Confirm with your legal counsel for your specific setup; the general shape is: no cookies + first-party + no cross-site sharing = no banner requirement.

  • Site performance stays fast

    A first-party cookieless tracker (linksync's /s.js is under 2 kB gzipped) has effectively zero performance cost. No third-party network hop, no cookie parsing on every request, no heavy fingerprinting code. Your Core Web Vitals do not pay a tax.

  • No third-party sharing to worry about

    Third-party analytics tools ship visitor data to their own servers, which is where the regulatory pain concentrates. First-party cookieless analytics stays on your domain (or on a domain you have a data-processing agreement with, in linksync's case), so the compliance story is one contract long, not five.

What cookieless analytics does not give you

  • Cross-page session stitching

    The traditional way analytics knows a visitor read three pages in one visit is a cookie that persists across page loads. Cookieless breaks that by design. linksync's cookieless mode handles it by passing a session identifier through the URL (the `_ls` query parameter) instead, but that identifier only survives as far as your links carry it. If a visitor navigates to another page on your site via a link that does not carry the parameter, the session ends.

  • Cross-device attribution

    Standard cookies never solved cross-device on their own; they needed a login event to stitch a phone visit to a desktop visit. Cookieless is the same here: no worse, no better. If cross-device is central to your analytics story, cookies alone would not have given it to you either.

  • Some attribution loss on multi-step checkouts

    linksync's cookieless mode relies on the `_ls` parameter reaching your checkout. If your checkout is a redirect to a payment processor that strips query parameters (Stripe preserves them via metadata, Shopify via note_attributes), or if a marketing tool between the click and the buy strips the parameter, revenue attribution can drop for that session. This is worth measuring against your specific checkout flow.

  • Third-party retargeting will not work

    The whole point of first-party cookieless is that you are not sharing data with third parties. That means no Meta / Google / Pinterest retargeting audiences populated from linksync's tracker. If you run paid ads that depend on retargeting, you keep pixels on your destination site separately (the ad network handles its own consent story), and use linksync for the organic-traffic per-platform view alongside it.

How to set up cookieless analytics with linksync

  1. Claim your linksync free

    Sign up at linksync.me. Free covers a bio page and up to five tracked short links with the standard first-party cookie. Cookieless mode is a Pro toggle on the tracker script.

  2. Install the /s.js tracker on your destination site

    In /app/install, register your destination domain and copy the snippet. It is a single <script defer> tag pointing at https://linksync.me/s.js with your website_id attribute. Under 2 kB, no third-party dependencies.

  3. Flip the cookieless toggle

    Above the snippet in /app/install there is a "Cookieless mode" toggle. Turning it on adds data-cookieless="true" to the script tag. The tracker no longer sets a cookie; sessions are handed off exclusively via the `_ls` query parameter from linksync-generated short URLs.

  4. Verify the `_ls` param survives to checkout

    For revenue attribution to work in cookieless mode, the `_ls` parameter must reach your checkout. On Stripe: read the `_ls` value from the URL on the checkout page and set metadata.ls_session on the Checkout Session. On Shopify: use note_attributes. On self-hosted checkout: preserve the parameter through your checkout redirect. linksync's Install wizard covers each of these paths.

  5. Confirm you do not need a cookie banner

    Review your setup with your legal counsel or your compliance advisor. The general shape of a banner-free setup is: no cookies set, first-party only (no third-party analytics or ad-network scripts on the same page), no cross-site tracking. If any of those are false (a Meta pixel elsewhere on the page, for example), you still need the banner for those other tools; linksync just does not contribute to the requirement.

Questions creators ask

Is cookieless analytics really GDPR compliant?

First-party cookieless analytics is designed to be used in line with GDPR expectations. The specifics depend on your setup and your jurisdiction. The strongest general statement is: not setting a cookie removes the cookie-consent requirement for that specific tool; not sharing data with third parties removes the third-party data-transfer question; keeping the tracker first-party removes the cross-site tracking question. Nothing removes the need for a privacy policy that discloses what you collect.

Does cookieless analytics mean I can skip the cookie banner entirely?

For linksync specifically, if it is the only analytics on your site and you have no other cookies set that require consent, most jurisdictions do not require a banner. If you also run Meta pixels, Google Analytics, or ad-network retargeting cookies, those still require consent, and linksync being cookieless does not remove that requirement.

What is the /s.js script and how big is it?

linksync's tracker script is a small first-party JavaScript file served from linksync.me. Under 2 kB gzipped. It has no third-party dependencies and no runtime network hops beyond one POST per view and one per conversion. Install it as a single <script defer> tag.

Does cookieless mode work with Stripe checkout?

Yes, as long as the `_ls` query parameter reaches your Checkout Session. Read the `_ls` value from your product-page URL and pass it as metadata.ls_session when creating the Checkout Session. Every completed checkout webhook then attributes back to the click that started the journey.

What is the difference between linksync default mode and cookieless mode?

Default mode sets a first-party cookie on your domain that stitches page loads for the same visitor into one session. Cookieless mode does not set any cookie; sessions are stitched via the `_ls` URL parameter alone. Default mode is more forgiving (a lost `_ls` param still finds the session via the cookie); cookieless is more privacy-conservative and requires the `_ls` param to survive to the destination.

What happens if the `_ls` param gets stripped somewhere?

In default mode, the first-party cookie takes over as a fallback. In cookieless mode, that specific session cannot be stitched to the click that started it, so revenue for it will end up counted under "direct" instead of the actual platform. Worth measuring against your specific redirect chain if you rely on cookieless.

First-party. Under 2 kB. Cookieless mode built in.

linksync's tracker runs on your own domain, does not need a banner in most setups, and still labels every click by platform. Free plan available.
