Cookie Policy
Last updated: July 2026
What we actually use
Less than most sites. We use browser local storage and a small number of cookies to make the site work, and no advertising cookies of our own. One third-party security service, Google reCAPTCHA, is described below.
| Name | What it does | How long |
|---|---|---|
| sd_cart | Keeps your campaigns in the cart between visits. Local storage, not a cookie, never sent to our server. | Until you clear it or check out |
| sd-dark | Remembers whether you turned on dark mode. | Until you clear it |
| sd-nav-user | Paints your account avatar instantly instead of waiting for a server round-trip. Session storage. | Until you close the tab |
| Firebase auth | Keeps you signed in. Set by Google Firebase Authentication. | Until you sign out |
| Stripe | Fraud prevention on the payment page. Set by Stripe only when you go to pay. | Per Stripe's policy |
| Google reCAPTCHA | Security. Checks that requests to our system come from a real browser on this website and not an automated script. Set by Google on every page. | Per Google's policy |
Google reCAPTCHA
We use Google reCAPTCHA v3 to protect our system from automated abuse. It runs invisibly, with no puzzles to solve and nothing to click. It looks at how the browser behaves to judge whether a request is genuine, and in doing so it sends device and usage information to Google and sets Google cookies. This is a security measure, not advertising, and we do not receive or use that information for marketing.
It is governed by Google's Privacy Policy and Terms of Service. If your browser blocks it, the site still works.
Analytics
If we run analytics, it is limited to aggregate page-view and referral data so we can tell which pages are working. We do not sell that data.
Advertising
We advertise on Facebook and Google. If you arrive from one of those ads, that platform may set its own cookies subject to its policy, not ours. You can control that through your Facebook ad preferences, your Google ad settings, or your browser.
Turning cookies off
Every browser lets you block or delete cookies and clear local storage. If you block them here, the site still works, but your cart will not persist between visits and you will not stay signed in.
