Privacy Policy
Last updated: 31 May 2026 · Applies to the Matome browser extension (v0a)
Matome is built local-first. Your notes live in your own browser. The extension has no server, no account system, and makes no requests to Pinterest on your behalf.
What Matome stores
When you save a Pin, Matome stores the following locally in your browser:
- The Pinterest pin URL — a deep-link string.
- The source URL — the underlying source page, if Pinterest exposes it.
- The image source URL — the address of the thumbnail Pinterest itself rendered, stored as a URL string, never as image bytes.
- Your rationale text — the one line you write, authored entirely by you.
- A timestamp and how long the capture took.
Where it is stored
All of the above is kept in your browser's local storage (chrome.storage.local and IndexedDB) on your device. Nothing is uploaded. There is no Matome server and no cloud sync in this version.
What Matome does NOT do
- It does not download or store Pinterest image files.
- It does not send any data to a server — ours or anyone else's.
- It does not call the Pinterest API or fetch pages in the background.
- It does not track you, use analytics, or run advertising.
- It does not read any site other than the Pinterest page you are actively viewing.
How Matome reads the page
Matome runs only on pinterest.com, inside your own browser session, on pages you have loaded yourself. When you click Pinterest's Save button, Matome reads the already-rendered page to capture the URLs listed above — the same basis used by ad blockers, dark-mode tools, and password managers. It never automates requests to Pinterest's servers.
Your control
Because the data lives in your browser, you can remove it at any time by clearing the extension's data or uninstalling it. Uninstalling Matome deletes everything it stored.
Permissions
Matome requests only the browser permissions it needs to detect saves on Pinterest, store notes locally, and open its review tab. It does not use these permissions to collect data beyond what is described above.
Changes
If this policy changes, the "last updated" date above will change with it.
