Cookie Policy
Effective October 1, 2026
This policy explains what SlabZen, operated by Bad Manatee LLC, stores on your device when you use slabzen.app. It's part of our Privacy Policy.
The short version: we don't use advertising, analytics or tracking cookies. We only store what's needed to keep you signed in, remember a few display settings, protect the site from bots, and, if you buy SlabZen Pro on the website, take your payment safely. On the sign-in page, Apple's and Google's sign-in tools may set their own cookies (see below).
What we store
| Name | Type | What it's for | How long |
|---|---|---|---|
| slabzen_auth | Browser storage | Keeps you signed in on this device. | Until you sign out |
| slabzen_prefs | Browser storage | Remembers display choices, such as how your collection is sorted, whether this device has signed in before (so the sign-in page opens on the log-in form rather than the sign-up screen), and whether a new account made here has seen the one-time plan choice after sign-up. | Until you clear it |
| __cf_bm | Cookie (set by Cloudflare) | Helps tell real visitors from bots, to protect the site. | 30 minutes |
| revenuecat_user_id | Browser storage (set by RevenueCat, our subscription provider, once you open the SlabZen Pro screen) | Remembers which SlabZen account a purchase belongs to. | Until you clear it |
| __stripe_mid, __stripe_sid | Cookies (set by Stripe, only once you open SlabZen Pro checkout) | Fraud prevention for payments. | 1 year and 30 minutes |
All of these are strictly necessary for SlabZen to work, so they don't need your consent and you won't see a cookie banner. The mobile apps store your sign-in on your device in the same way.
Sign in with Apple or Google
To offer "Continue with Apple" and "Continue with Google," our sign-in page loads Apple's and Google's own sign-in tools. They may set or read their own cookies, under their own policies (Apple, Google), particularly if you use those buttons. These tools only load on the sign-in page, not once you're signed in.
Links to other sites
Some links, such as "find it on eBay," take you to other websites. Some are affiliate links: if you buy something, we may earn a commission at no cost to you. Those sites, including eBay, set their own cookies when you arrive there, under their own cookie policies. SlabZen doesn't set or read them.
Your choices
- Signing out removes your sign-in from this device.
- You can clear everything in your browser's settings (look for "site data" or "cookies and site data"). You'll be signed out.
- Blocking all cookies and site data will stop SlabZen from keeping you signed in.
Changes
If we ever add analytics or other non-essential cookies, we'll update this policy first, and we'll ask for your consent where the law requires it.
