The short version: Prop Streak Lab does not use cookies, advertising trackers, or cross-site tracking. To work, it saves a little information in your browser's local storage, which stays on your device. Analytics are cookieless.
We use your browser's local storage — not cookies — to remember your preferences between visits. Apart from the daily page count, the new-or-returning flag and its days-visited range, the Simple or Pro choice and the affiliate code below, this information never leaves your device and is not transmitted to us:
| What | Why |
|---|---|
| Watchlist & comparison list | Remember the players you've saved or are comparing. |
| Recent inputs & view preferences | Keep the tools set the way you left them. |
| Simple or Pro view | Remember which view of the sport pages you chose, and that you were asked. When you choose or switch, our analytics receives just "Simple" or "Pro", to count how many people use each; nothing that identifies you. |
| Notice dismissed | Remember that you've closed the privacy notice so it doesn't reappear. |
| Pages viewed today | A running count (1, 2, 3 ...) that resets each day. It's one exception to "never leaves your device": with each page, our analytics receives just that number, such as "page view 3", so we can count page views and unique visitors without identifying anyone. |
| Date of your first visit | So our analytics can count returning visitors. Only "new" or "returning" is sent, once a day; never the date itself or anything that identifies you. |
| Number of days you've visited | So our analytics can see how often returning visitors come back. Only a range (2, 3-4, 5-9 or 10+ days) is sent, once a day; never the count itself or anything that identifies you. |
| Affiliate code | Only if you arrive through an affiliate's link (ending in ?ref= and a code). Kept in session storage, which clears when you close the tab, to time your visit across pages. Our analytics receives the code, "new viewer" once if this is your first visit (after 20 seconds on screen), so we can pay the affiliate, and how long the visit lasted as marks such as "10 seconds" or "1 minute"; nothing that identifies you. |
You can delete all of this at any time by clearing site data in your browser settings. The site keeps working if you do — it just forgets your preferences.
We use GoatCounter to count visits and see which pages are popular. It sets no cookies, uses no persistent identifier, and does not track you across other sites. See our Privacy Policy for what it records.
The site does not use advertising, retargeting, or social-media marketing cookies or pixels, with one exception: our ad landing page (propstreaklab.com/start), where people arrive from our paid ads, asks whether you accept Google Ads measurement. Only if you choose Accept does it load Google's tag, which sets Google advertising cookies so we can see which ads bring visitors who sign up. If you choose No thanks, nothing loads; your choice is remembered in local storage and can be changed from the link at the bottom of that page. No other page loads it.
Some content loads directly in your browser from third parties (a CDN used only for the bet-slip screenshot tool, and Polymarket for live prices). The site's fonts are self-hosted, so no font provider is contacted. We don't set cookies through these services for our own purposes; any storage they use is governed by their own policies, listed in our Privacy Policy.
Across the site we only use essential local storage and cookieless analytics, so no consent gate is needed; we show a short notice for transparency, which you can dismiss. The one exception is Google Ads measurement on the ad landing page, which stays off until you accept it there.
