Cookie Notice

We may use pixels, tags, or web beacons on pages or emails to understand whether pages were viewed, links were clicked, messages were opened, or product flows are working.

For our own campaign measurement, a provider such as Meta may receive signup, first-product-activation, or paid-subscription events plus identifiers used for attribution, such as a hashed email or account ID, IP address, browser user agent, campaign cookie identifiers, plan, currency, and transaction value where relevant. We do not send names, phone numbers, birth dates, or precise location for these events.

An eligible paid landing may create an encrypted LinkStack attribution cookie containing campaign, ad, placement, landing-page, referrer, and advertising click or browser identifiers. It contains no email or LinkStack account ID before signup, expires after 30 days, and may be removed earlier after a matched signup.

The first-party ls_signup_acquisition cookie preserves an initial visit for signup analytics for up to 30 days, including visits without an ad. It stores available UTM values, a landing page without query parameters, a referring website without its path or query parameters, and an optional Google or Meta click-source hint. It contains no email, account ID, or advertising click ID. Supported Global Privacy Control signals disable this capture. The context may be saved with an account before email confirmation.

When you visit the LinkStack homepage or a LinkStack marketing page through a valid LinkStack affiliate link, a first-party referral token may preserve the first qualified affiliate for up to 180 days. Before signup, the token is random and does not contain your email or LinkStack account ID. LinkStack records the referral name, landing path without query parameters, referring website origin, click time, approximate country, region, and city, affiliate link placement (such as a bio corner, bottom bar, or shared link), and derived device, browser, operating-system, and traffic-source details. The affiliate click record does not store your raw IP address. If you create an account during the window, the affiliate relationship may be locked to that account and the browser token removed.

If LinkStack offers a mobile app or integrates mobile SDKs, those SDKs may help provide analytics, crash reporting, login, payments, social features, or security.

Browser controls: most browsers let you block, delete, or limit cookies in settings. If you disable cookies, parts of LinkStack may not work, and you may need to log in again.

Device controls: mobile devices may let you limit advertising identifiers or reset tracking identifiers.

Industry tools: some advertising providers participate in opt-out tools from groups like the Network Advertising Initiative, Digital Advertising Alliance, or your browser's privacy controls.

Global Privacy Control: where required by law and technically supported, we will treat a valid Global Privacy Control signal as an opt-out request for that browser.

We may update this Cookie Notice as LinkStack changes or as our providers change. The effective date above shows when this notice was last updated.
