This Privacy Policy describes how MyMemos (“we”, “us”) handles information when you use the MyMemos browser extension, the optional live demo at /demo/, and this marketing website.
Summary
MyMemos is local-first. Your notes, folders, images, and voice notes are stored on your device. We do not require an account, and we do not operate a sync server for your content. Nothing you write in the extension is uploaded to a MyMemos backend for storage.
Browser extension
What we store on your device
- Pages and folders - document content (block JSON) in the browser’s IndexedDB database for this extension.
- Images and voice / audio attachments - binary files in the Origin Private File System (OPFS) on your device. Paths and metadata are referenced from your notes.
- Settings - preferences such as theme, last opened view, custom themes, collapsed folders, and product-tour status in
chrome.storage.local(or the extension’s equivalent local settings store).
This data stays in your browser profile. Uninstalling the extension or clearing site / extension data may permanently delete it. We cannot recover content we never received.
Permissions
The extension requests only the permissions needed to replace your New Tab and save settings (for example, storage). It does not request access to your browsing history or to read arbitrary websites for advertising.
Network activity
Core note-taking does not send your pages or attachments to our servers. Some optional editor features (such as fetching a pasted image URL) may contact a third-party host you chose; that request goes from your browser to that host, not through a MyMemos content API.
Live demo (/demo/)
The web demo runs the same UI in your browser. Pages use IndexedDB and settings use localStorage for that website origin. Demo data is separate from the installed extension and does not sync with it. Clearing site data for the demo origin removes demo notes.
Marketing website
This site may use standard hosting and delivery infrastructure (for example CDN-hosted media such as the launch video). The site may also load privacy-respecting web analytics provided by the host (for example Vercel Analytics) to understand aggregate traffic. Analytics on the marketing site are separate from extension note storage and do not include the contents of your notes.
Server logs typical of web hosting (such as IP address, user agent, and requested URL) may be processed by the host briefly for security and reliability.
Changes
We may update this policy as the product evolves. The “Last updated” date at the top will change when we do. Continued use after an update means you accept the revised policy.
