Cookie policy
Last updated 5 October 2026
We use as little as we can, and nothing for advertising.
This website and the merchant panel
When you first visit, a banner asks what you allow. Cookies are grouped as necessary (always on), analytics and advertising. Nothing in the analytics or advertising groups is stored until you agree, and "Reject" is as easy as "Accept all". Change your choice at any time with Cookie settings in the footer of the website or the sidebar of the panel. Your choice is kept for 180 days and shared between chatnsell.co and the panel.
Before you choose, Google Analytics runs in Google's Consent Mode: it may send cookieless, anonymous pings, but stores nothing on your device.
| Name | Group | Set by | Purpose | Kept for |
|---|---|---|---|---|
cns_consent | Necessary | Chat'N'Sell | Remembers your cookie choice. | 180 days |
cns_attr | Necessary | Chat'N'Sell | Where your first and latest visit came from (campaign tags such as utm_source, or an ad click id), so we know which campaigns bring merchants. Stays on your device until you sign up. | 90 days |
| Session and security cookies | Necessary | Chat'N'Sell (panel) | Keep you signed in and protect forms against cross-site attacks. | Until you sign out |
_ga, _ga_* | Analytics | Google Analytics 4 (Google Ireland Ltd) | Count visits and see how the site and panel are used. | Up to 2 years |
Google Ads cookies (_gcl_*) | Advertising | Google Ads (Google Ireland Ltd) | Measure which Google ads lead to sign-ups and subscriptions. | 90 days |
_fbp, _fbc | Advertising | Meta Pixel (Meta Platforms Ireland Ltd) | Measure which Facebook and Instagram ads lead to sign-ups and subscriptions, and show our ads to people likely to find them useful. | 90 days |
With advertising consent, the panel also tells Meta (Conversions API) and Google (GA4 Measurement Protocol) from our server when a sign-up, store setup or subscription happens, so the count stays right when a browser blocks scripts. These messages carry your email address only as an irreversible hash, plus the identifiers above. No advertising data is sent if you refused advertising cookies.
The Mini App storefront
- The storefront stores small preferences on the shopper's device, such as recently viewed products and whether the "add to home screen" tip was dismissed. Shoppers are identified by Telegram, not by cookies.
If we add anything else that needs consent, we will list it here and ask you again. See also our privacy policy.
