Privacy Policy

Muchita Shopping

Effective date: June 7, 2026

Muchita Shopping is a Chrome extension that helps you find out whether the product you're looking at is available cheaper elsewhere. This policy explains exactly what it reads, what happens in your own browser session, what (if anything) is sent to us, and what it never does.

The guiding principle is simple: the extension does its work in your browser, only when you ask, and keeps your data on your side. There is no account and no tracking.

At a glance

  • No account or sign-in. No analytics unless you turn them on — off by default.
  • Product detection runs locally in your browser, only ever acts on product pages, and is additionally switched off on a list of major banking, payment, sign-in, webmail, and health sites.
  • A price check runs only when you click it, and it uses your own browser tab and session.
  • We never inject affiliate links or cookies, never modify checkout, and never bypass security checks.
  • The only thing sent to us is a "found a better price?" report — and only if you choose to send one.

What the extension does with page content

To know whether you're on a product page, a component of the extension reads the content of pages you visit (for example structured product data, the product name, price, and image). This happens locally, in your browser, and is used only to detect products and to compare the item you're viewing against offers found elsewhere.

As an additional safeguard, detection is switched off on a curated list of major sensitive sites — well-known banking, payment, sign-in, webmail, and health services. That list cannot include every such site, so the protections that always apply are these: detection only reads a page locally to recognize a product, the on-page prompt appears only on product pages, and a price check runs only when you start one.

The extension does not modify the pages you visit beyond showing its own small "check price" prompt, and it does not read page content for any purpose other than the price-comparison feature described here.

What happens when you run a price check

When you start a check, the extension navigates your active browser tab — in your own, already-logged-in session — to Google (Google Lens, Google Shopping, and Google Search) and then to the online stores that appear to carry the product, in order to read their current prices. When the check finishes, it returns your tab to the page you started from.

Because this uses your own browser and session, those third parties (Google and the retailers) receive requests as if you had visited them yourself, and their handling of that activity is governed by their own privacy policies. Muchita AI does not receive a copy of your searches or the pages visited during a check.

If Google shows a "verify you're human" (CAPTCHA) check, the extension surfaces it so you can solve it yourself and then continues. It never bypasses, evades, or automatically solves these checks.

Information sent over the network

The extension makes a small number of network requests:

  • Currency rates. To compare prices in your preferred currency, it fetches public exchange-rate data from a content-delivery network. These requests contain only a currency code — no personal data.
  • Product images. To confirm two listings are the same item, it fetches product images and computes a small visual "fingerprint" (a perceptual hash) in your browser. Images are not uploaded to us or stored by us.
  • "Found a better price?" reports (optional). If you tap to report a cheaper offer we missed, the extension sends the product page you checked, the page you reported, and the parsed offer to our feedback service so we can improve which offers we find. This is the only data the extension sends to Muchita AI, and only when you choose to send it.

Our feedback service runs on Cloudflare (a Worker plus a database) at feedback.muchita.ai. It receives only what is described above; please don't include anything sensitive in a report.

Optional usage analytics

To understand how the extension is used and improve it, you can turn on anonymous usage analytics in Settings. It is off by default — nothing is sent unless you enable it.

When enabled, the extension sends a small set of product-usage events — for example "price check started", "better price found" (with a rough savings range), "deal clicked", and "check completed" (with the outcome) — to Google Analytics, identified only by a random, anonymous id stored on your device. It never sends the pages you visit, the product URLs, your search queries, page content, or any personal information, and it is never used to build an advertising or behavioral profile of you. You can turn it off again at any time.

What we do not do

  • No user accounts and no sign-in.
  • No advertising and no advertising identifiers. Analytics are optional, off by default, anonymous, and product-only (see above).
  • No selling or renting of personal information, and no building of advertising or behavioral profiles.
  • No affiliate links, no affiliate cookies, and no changes to checkout or payment.
  • No bypassing of CAPTCHAs, paywalls, or login restrictions.

Permissions and why they're needed

  • Access to websites (host access). Products can appear on any online store, and a check must read prices on whichever retailers carry the item, so the extension needs access to web pages generally. It uses this only for product detection and price comparison, and it is excluded from sensitive sites.
  • Tabs, scripting, and web navigation. Used to drive your tab through the price check (navigate to results, read the current page, detect when a page has loaded) and to return you to your product page afterwards.
  • Tab groups. Used to group the pages a check opens so your window stays tidy.
  • Storage. Used to remember your settings (such as preferred currency and theme) and to cache exchange rates. This stays in your browser.
  • Side panel. The price-comparison results are shown in Chrome's side panel.

Data storage and retention

Your settings and cached exchange rates are stored locally in your browser and remain until you clear them or remove the extension. Research results are kept only for the current session.

"Found a better price?" reports you choose to send are retained by Muchita AI only as long as reasonably needed to analyze and improve the product, and to prevent abuse.

Third-party services

  • Google (Google Search, Google Lens, and Google Shopping), accessed through your own browser session during a check.
  • Online retailers whose product pages are visited during a check.
  • A public exchange-rate content-delivery network (jsDelivr / a currency-rates API) for converting prices.
  • Cloudflare, which hosts muchita.ai and our optional feedback service.
  • Google Analytics — only if you opt in to usage analytics, and only the anonymous events described above.

These third parties process information according to their own privacy practices.

Children

Muchita Shopping is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

Changes to this policy

We may update this Privacy Policy when the extension or our practices change. The effective date at the top shows when it was last updated.
