FYM - Free Your Mind

FYM is a Chrome extension for one simple purpose: save the current web page and receive a reminder for it later.

The reminder can be scheduled for an exact date and time, or after a countdown. FYM stores the page URL, title, detected language and a visual preview, then shows a Chrome notification when the reminder is due.

Single Purpose

FYM creates reminders linked to saved web pages.

It does not try to be a general bookmark manager, task manager or note-taking tool. Its only goal is to help users reopen a specific web page at the right moment.

Features

• Save the active tab URL and title.
• Capture a preview image of the current page.
• Create a reminder by date and time.
• Create a reminder by countdown.
• Show a Chrome notification when the reminder is due.
• Open the saved page from the reminder notification.
• View and delete saved reminders from the options page.
• Localized UI through Chrome i18n.
• Manifest V3 compatible.

Project Structure

The extension source lives in:

master/fym/

Main files:

master/fym/manifest.json       Chrome extension manifest
master/fym/background.js       Service worker for reminder checks and notifications
master/fym/fym.html            Extension popup
master/fym/fym.js              Popup and options page logic
master/fym/options.html        Saved reminders list
master/fym/style.css           Shared styles
master/fym/_locales/           Chrome i18n messages
master/fym/webstore-assets/    Chrome Web Store listing images

Install Locally

1. Open Chrome and go to chrome://extensions.
2. Enable Developer mode.
3. Click Load unpacked.
4. Select the folder:

master/fym/

Build Chrome Web Store ZIP

The Chrome Web Store expects a ZIP file with manifest.json at the archive root.

A generated package is available at:

dist/fym-chrome-webstore-v0.3.1.zip

The ZIP contains only the extension runtime files. Web Store listing assets are kept outside the runtime package.

An Opera Add-ons compatible package is also generated at:

dist/fym-opera-addons-v0.3.1.zip

This Opera package includes _locales and keeps default_locale so Opera Add-ons can use the translated metadata and UI strings.

Permissions

FYM uses a minimal set of permissions for its single purpose.

• activeTab: read the current tab only after the user opens the extension, and capture its visible preview.
• tabs: read the active tab title and URL, and open a saved URL from a reminder notification.
• alarms: check periodically whether a reminder is due.
• notifications: display the reminder notification.
• storage: save reminders locally in Chrome.

FYM does not use remote code. JavaScript files are packaged inside the extension.

Privacy

Reminder data is stored locally with chrome.storage.local.

Older versions stored reminders in IndexedDB. Version 0.3.1 automatically migrates existing IndexedDB reminders to chrome.storage.local the first time the extension starts, popup opens or options page opens.

Stored data can include:

• Page URL
• Page title
• Detected page language
• Reminder date or countdown
• Captured page preview

FYM does not send this data to a remote server.

Chrome Web Store Assets

Listing assets are available in:

master/fym/webstore-assets/

Included assets:
