Summary
The version
in human words.
- 01We use 9 cookies total. Three are strictly necessary, three are optional analytics/preference cookies, and three are advertising cookies.
- 02We use Meta Pixel and Google Ads remarketing to show ads to people who visited Luckiest. These require your consent and are off by default.
- 03Analytics is privacy-friendly, first-party only, and you can switch it off at the banner.
- 04Your choice is stored for 12 months, then we ask again.
- 05Block cookies in your browser if you prefer the nuclear option — the site still works, mostly.
01/The Primer
What a cookie is
A cookie is a small text file your browser stores when you visit a site. The site can read its own cookies on subsequent visits. We also use a couple of related technologies — local storage and session storage — and we lump them all together as "cookies" in this document for clarity.
02/Full Inventory
Every cookie we set
The complete list. If we add a cookie, we update this section, bump the version above, and ask for consent again where required.
Strictly necessary — always on
- lk_session
- Authentication token. Expires when you log out or after 30 days of inactivity.
- lk_csrf
- Cross-site request forgery defense. Session-only, cleared on tab close.
- lk_consent
- Your cookie preferences. 12 months. Always required to remember 'no thanks.'
Optional — off until you opt in
- lk_locale
- Preferred language / currency on the marketplace. 12 months. Saves you a click.
- lk_seen
- Listings you've viewed, used to power 'recently browsed.' 30 days.
- lk_metric
- Anonymous analytics ID (Plausible-style). No fingerprinting, no cross-site tracking.
Advertising — off until you opt in
These cookies are set by third-party advertising platforms when you accept the advertising category at the consent banner. They are not loaded at all if you decline.
- _fbp
- Meta Pixel browser ID. Used by Facebook/Instagram to measure ad conversions and build retargeting audiences. Set by Meta, governed by Meta's Data Policy. Up to 90 days.
- _fbc
- Meta click ID, stored when you arrive via a Facebook ad. Ties your visit to a specific ad click for attribution. Up to 90 days.
- _gcl_au
- Google Ads conversion linker. Measures whether a Google ad click led to an action on Luckiest (e.g. submitting an offer). Set by Google, governed by Google's Privacy Policy. 90 days.
03/Outside Code
Third-party cookies
We use Meta Pixel and Google Ads remarketing to run retargeting campaigns — showing ads on Facebook, Instagram, and Google to people who have visited Luckiest. These tools set the advertising cookies listed in section 02 above. They are loaded only if you accept the advertising category at the consent banner; if you decline or ignore the banner, these scripts do not run.
Three operational third-party cookies are always present regardless of your advertising choice: Stripe sets cookies during checkout to prevent payment fraud, and Cloudflare may set a security cookie (__cf_bm) to distinguish browsers from bots. Both are scoped to specific actions and lifetimes and covered by their providers' policies, linked in our subprocessor list.
Your opt-out rights
California residents (CCPA) may opt out of the sale or sharing of personal information for advertising at any time using the cookie preferences panel in the footer. EEA and UK residents (GDPR / UK GDPR) must opt in before advertising cookies are set — consent is never assumed. You may also opt out directly at Meta Ad Preferences and Google Ad Settings.
04/Your Switches
Your controls
You have three layers of control. Each one is stronger than the last; all three are honored.
- Banner
- On first visit, you can accept all, reject all, or pick by category. Stored for 12 months.
- Footer
- A 'Cookie preferences' link in the footer reopens the same dialog at any time.
- Browser
- Browser-level blocking. We respect Global Privacy Control automatically.
Do Not Track & Global Privacy Control
We honor the Global Privacy Control (GPC) signal as a binding opt-out of optional cookies. Browsers that send a Do Not Track header are treated identically. You don't need to do anything else.
05/Change Log
Changes
If we add or change a cookie, we update this page and re-prompt for consent on the affected categories. Material changes are also announced by email to active accounts.
