The short version

Marhiv does not collect, store, or transmit your personal information. The browser extension runs entirely on your own device, keeps its settings locally, and operates inside the AI-chat sessions you are already signed in to. There are no Marhiv accounts, no Marhiv servers, no analytics, no trackers, and no advertising. We have nothing to sell because we collect nothing.

1. Scope

This policy covers both the Marhiv website (marhiv.app) and the Marhiv browser extension. Marhiv is open-source software released under the Apache-2.0 license; you can read every line of its source to verify the claims below.

2. The Marhiv extension

Marhiv is a Chromium extension that layers enhancements onto AI chat sites you already use. By design, it works with your local setup and your existing sessions — it does not introduce any account, cloud service, or backend of its own.

Runs locally. All of Marhiv’s logic executes in your browser. It has no server to send anything to and does not “phone home.”
Settings stay on your device. Preferences such as the Menu Ball position, panel size, and which plugins you’ve enabled are saved with your browser’s local extension storage (chrome.storage.local). They never leave your machine and are not visible to us.
Uses your own sessions. Marhiv acts within the AI site you are already logged in to, using that site’s normal session in your browser. It does not collect, read, or store your credentials, and it never creates a separate login.
No telemetry or analytics. Marhiv contains no usage tracking, no crash reporting, and no advertising or fingerprinting code.
Network requests. Some plugins may make requests to the AI site you are currently using (for example, to power a shortcut) using your existing session. Those requests go directly to that site — the same destination the site’s own page would call — and are never routed to Marhiv or any third party.
Userscripts are yours. Any userscript you write or paste runs locally, under your control, through your browser’s sanctioned scripting API. You are responsible for the behavior of scripts you choose to run.

Permissions, briefly

Marhiv requests the narrowest permissions it needs: local storage (to remember your settings) and access to the supported AI site(s) it enhances (so it can run on those pages). It does not request broad access to all of your browsing.

3. This website

The marhiv.app website is a static, informational site.

No accounts and no cookies set by us. The site does not ask you to sign in and does not place tracking or advertising cookies.
No analytics. We do not run analytics, tag managers, or behavioral tracking on the site.
Standard server logs. Like virtually all websites, the hosting server may briefly process standard request data (such as your IP address and browser user-agent) to deliver pages and protect against abuse. This is not used to identify you or build a profile.
Web fonts. The site loads the Inter typeface from Google Fonts. As a result, Google may receive your IP address when fonts are fetched, subject to Google’s own privacy policy.
Outbound links. Links to GitHub, the Chrome Web Store, and similar services take you to third parties governed by their own privacy policies.

4. What we do not collect

To be explicit, Marhiv does not collect your name, email address, account credentials, the contents of your AI conversations, your browsing history, your location, or any analytics or advertising identifiers.

5. Third-party services

Marhiv enhances AI chat products you choose to use (such as Claude, and in the future ChatGPT and Gemini). Your use of those products — and of services like GitHub or the Chrome Web Store — is governed by their respective privacy policies, not this one. Marhiv does not control and is not responsible for those services’ data practices.

6. Children’s privacy

Marhiv is a general-purpose developer and power-user tool and is not directed to children. We do not knowingly collect personal information from anyone, including children.

7. Transparency & open source

Marhiv is open source. If you want to confirm exactly what it does, the complete source code is publicly available on GitHub.

8. Changes to this policy

If this policy changes, we will update the date at the top of this page and reflect the change in the public repository’s history. Material changes will be noted there.
