When you visit SGT Cart (sgtcart.com) or use one of our mobile apps, we and our partners store small pieces of data on your device — called cookies, local storage and similar technologies — to keep the site working and to learn how it can be improved. This Cookie Policy lists what we set, why, and how you can switch optional cookies on or off.
1. What is a cookie?
A cookie is a tiny text file that a website asks your browser to save and send back on subsequent visits. It typically contains a session identifier, a preference setting or a consent flag — never your password, never your card number.
The Platform also uses related technologies that behave similarly:
- Local Storage / Session Storage — key-value pairs your browser keeps for our pages (e.g., your
sgt_voice_lang,sgt_wishlist,sgt_cookie_consent). - IndexedDB — used by the chat module for offline-message buffering.
- Service Worker cache — when the mobile app is installed as a PWA, certain static files are kept locally so the app loads faster.
Throughout this page, "cookie" refers to all of these collectively.
2. Why we use them
- Keep you signed in — without a session cookie you would have to log in on every page.
- Remember your cart — items survive a browser restart.
- Remember preferences — language (EN / BN), wishlist items, cookie consent choice, voice-search language, viewed-product history.
- Protect against attacks — anti-CSRF token, rate-limit fingerprint, fraud-detection signals.
- Measure performance — aggregate, first-party-only analytics: how many people view a product, where pages slow down, which features are used.
- Personalise — "Recently viewed", "Customers Also Viewed", recommendations on the home page.
We do not run third-party advertising cookies on SGT Cart. We do not allow ad networks (Google Ads, Facebook Pixel, TikTok Pixel) to track you across other websites. This is a deliberate choice — if it ever changes, this page will be updated and a fresh consent banner will be shown.
3. Categories & full list
3.1 Strictly necessary (always on)
These cookies are essential for the Platform to function. Without them you cannot log in, place an order, or use the cart. They cannot be turned off via consent — but you can block them in your browser settings, at the cost of breaking the site.
| Name | Purpose | Lifetime |
|---|---|---|
session | Flask session identifier — holds your login state. | Browser session |
csrf_token | Anti-CSRF token to protect forms from cross-site request forgery. | Browser session |
remember_token | "Remember me" persistent login. Set only if you tick the box. | 30 days |
sgt_cookie_consent (localStorage) | Records whether you chose "Accept all" or "Necessary only". | 1 year |
3.2 Preferences (always on; non-tracking)
These cookies remember choices you made for a better experience. They are not used for analytics or marketing.
| Name | Purpose | Lifetime |
|---|---|---|
locale | Your language choice (en / bn). | 6 months |
sgt_voice_lang (localStorage) | Voice-search recognition language (en-US / bn-BD). | Until cleared |
sgt_wishlist (localStorage) | Product IDs you've added to your wishlist (until DB wishlist ships). | Until cleared |
sgt_doc_lang (localStorage) | Bilingual toggle preference on legal pages (EN / BN). | Until cleared |
sid | Anonymous viewer ID for the "X viewing now" badge. | Browser session |
3.3 Analytics (set only after "Accept all")
First-party analytics help us understand which pages are popular, which load slowly, and where users drop out — so we can fix what's broken. Aggregated, not tied to your identity.
| Name | Purpose | Lifetime |
|---|---|---|
sgt_a | Anonymous analytics visitor identifier (random, not linked to your account). | 2 years |
sgt_sess | Per-session bucket for "this visit" measurement. | 30 minutes |
Analytics cookies are off by default. They are set only if you tap "Accept all" on the consent banner. We do not currently use Google Analytics, Mixpanel, Adobe Analytics or any other third-party analytics vendor — only first-party counters.
3.4 Marketing (none today)
We do not currently set any marketing cookies. If this ever changes, this section will list each cookie and we will trigger a fresh consent banner before activation.
4. Your consent
The first time you visit SGT Cart from a new device or after clearing browser storage, you see a banner at the bottom of the page asking:
"SGT Cart uses essential cookies to keep you signed in and your cart working. We'd also like to set optional analytics cookies to help us improve the site."
You have two choices:
- "Accept all" — necessary + preferences + analytics. Stored as
sgt_cookie_consent = "all". - "Necessary only" — only the cookies the site cannot work without. Stored as
sgt_cookie_consent = "necessary".
The banner does not re-appear on subsequent pages. To change your choice later, see §5.
5. How to control cookies
5.1 On SGT Cart
To revisit your cookie-consent choice on this device:
- Open your browser's developer tools (F12).
- Go to Application → Local Storage → https://sgtcart.com.
- Delete the key
sgt_cookie_consent. - Reload the page — the banner will re-appear.
A friendlier user-facing toggle ("Cookie preferences" link in the footer with a dialog) will land in a later release. Until then, the above is the supported method.
5.2 In your browser
All major browsers let you block, view or delete cookies entirely:
- Chrome: Settings → Privacy & security → Cookies and other site data.
- Firefox: Settings → Privacy & Security → Cookies and Site Data.
- Safari: Preferences → Privacy.
- Edge: Settings → Cookies and site permissions.
- Mobile: Settings of the respective browser app.
If you block all cookies — including strictly necessary ones — most of SGT Cart's features (login, cart, checkout, chat) will stop working. We don't recommend this for normal use.
5.3 "Do Not Track" signals
Modern browsers can send a "Do Not Track" header. Because there is no consensus standard, we currently treat DNT signals as advisory rather than as a blanket opt-out. We do not load any tracking cookies regardless of the DNT header — so the practical outcome is the same as if we honoured it.
6. Changes & contact
When we add a new cookie or category, we update this page and — if the change is material — show a fresh consent banner. The "Last reviewed" date at the bottom of this page always reflects the current state.
