Privacy policy

Your chats stay on your device

Effective 15 October 2026 · Covers the mcosec.ai Chrome extension (version 3.0 and later) and this website.

  • 0 servers see your chats
  • 0 trackers or ads in the extension
  • 0 accounts needed
Short version: the mcosec.ai extension works entirely inside your browser. It has no servers, no accounts, no analytics and no ads, and nothing you type or read is sent to us. The only time we receive personal information is if you choose to support us with a payment.

What the extension reads

The extension only runs on chatgpt.com, chat.openai.com, claude.ai and gemini.google.com. It never presses Send for you.

What is stored, and where

Everything the extension stores stays in your own browser profile, on your device:

WhatWhereHow long
The last chat you read and its compacted version (so it survives the popup closing)Extension's local database (IndexedDB)Until you press Clear, read another chat, or use Delete all data
Saved prompts, handoffs and feedback (extra tools only)Extension's local databaseUntil you delete them
Usage counts: numbers only (chats read and moved, estimated tokens saved, which AI sites, per day for 90 days). No chat text.chrome.storage.localUntil you press Reset counts or Delete all data
Settingschrome.storage.localUntil you remove the extension
Text waiting to be placed in a newly opened AI tabchrome.storage.sessionUsed once, removed within 5 minutes

You can export or delete all of it in the extension's Settings. Removing the extension removes it all.

What is sent, and to whom

Nothing is sent by the extension. Its pages are blocked by their security policy (connect-src 'none') from making any network request.

Text only leaves your device when you send it: after "Copy and continue", the compacted chat is in the new AI site's message box, and it goes to that AI company only if you press Send there. That company's own privacy policy then applies.

This website and support payments

What we do not do

Your rights

You can ask us to see, correct or delete the payment or contact details we hold about you, subject to the records the law requires us to keep. Email us and we will reply within 30 days.

Children

mcosec.ai is not directed at children under 13, and we do not knowingly collect information from them.

Changes

If a future version changes what is read, stored or sent (for example, the planned Pro features), this policy will be updated before that version is published, and any online feature will be opt-in.
