Privacy Policy

Plain English, not legalese. We believe you should understand exactly what happens with your data.

      The short version: mem/do stores everything on your device. We don't collect, transmit, or have access to any of your data. We can't see what you browse. We don't want to.
    

What mem/do does

mem/do is a Chrome extension that helps you remember and search what you've browsed. It captures page titles, summaries, and key information from websites you visit, then stores that information locally in your browser.

Where your data lives

All your data is stored locally on your device using your browser's built-in storage (IndexedDB). It never leaves your device. There is no cloud storage, no server sync, and no remote backup in the current version.

Your memories live in your browser's local database
All data is encrypted at rest with AES-256-GCM
The encryption key is stored in your browser and never transmitted

What we collect

Nothing.

mem/do does not send any data to any server. Specifically:

No analytics or usage tracking
No crash reports or error logging
No browsing history transmission
No user accounts or registration
No cookies for tracking purposes
No third-party scripts or SDKs that collect data

Network requests

mem/do makes two types of network requests, and only these two:

Favicon loading: When displaying website icons, your browser may load favicons from Google's favicon service. This is standard browser behavior.
AI model download (one time): On first use, mem/do downloads a small AI model (~22MB) for semantic search. This happens once and the model is cached locally. No user data is sent during this download.

AI processing

mem/do uses AI to summarize pages and enable natural language search. All AI processing happens entirely on your device:

Chrome's built-in AI (when available) runs on-device
The semantic search model runs locally in your browser
No page content is ever sent to any AI service

What mem/do skips

mem/do automatically excludes sensitive sites by default:

Banking and financial sites
Password managers
Login and authentication pages
Email clients
Health portals

You can customize these exclusions at any time in Settings.

Your control

You have complete control over your data:

View: See every memory mem/do has captured
Delete: Remove any individual memory instantly
Delete all: Wipe all data with one action
Export: Download all your data as a JSON file
Import: Restore from a previous export
Pause: Stop capturing at any time with one click

Permissions explained

mem/do requests the following Chrome permissions:

storage: To store your memories and settings locally
sidePanel: To display the side panel interface
activeTab: To read the current page when capturing
tabs: To detect when you navigate between pages
alarms: For periodic maintenance tasks (cleanup, digests)
host_permissions (all URLs): Required for the content script that extracts page text. This is the broadest permission we request, and it's used solely to read page content for memory creation. No data is transmitted.

Children's privacy

mem/do is not directed at children under 13. Since we don't collect any data, there is no children's data to protect, but we want to be clear about our intended audience.

Changes to this policy

If we ever change how data is handled (for example, adding optional cloud sync), we will:

Update this policy before launching the feature
Make any new data sharing strictly opt-in
Clearly explain what changes and why
Never retroactively change how existing data is handled
