Privacy Policy — Preamble

Last updated: May 12, 2026

TL;DR

Preamble stores your context library entirely on your own device. Your memories never leave your computer. We have no servers, no accounts, no analytics, and no tracking. There are zero outbound network requests.

What the extension does

Preamble lets you store short text “memories” (your background, projects, preferences, tools, writing style) and copy a formatted version of them to your clipboard, so you can paste them as a context prefix into any AI chat tool.

All of that happens locally:

1. You type memories into the side panel.
2. They’re saved in your browser’s local storage (chrome.storage.local).
3. When you click “Copy as prompt,” the selected memories are formatted and written to your clipboard.
4. You paste them wherever you want.

What data we collect

None. We do not operate any servers. The extension never makes outbound network requests. Your memories cannot be sent anywhere because there is nowhere for them to be sent.

The extension does not use cookies, analytics SDKs, advertising, or any third-party tracking.

Local storage

Memories are stored in chrome.storage.local on your device. They are accessible only to this extension and cannot be read by websites you visit. If you uninstall the extension, the stored memories are deleted with it.

Permissions explained

The extension’s manifest requests these permissions:

• storage — to save your memory library locally
• sidePanel — to open the Preamble side panel when you click the toolbar icon or press the keyboard shortcut

No host permissions are requested. The extension does not access content on any website you visit.

Clipboard

Preamble writes to your clipboard when you click “Copy as prompt.” It never reads from your clipboard.

Children

The extension is not directed at children under 13. It collects no information.

Changes to this policy

If we ever add a network-dependent feature (e.g., cloud sync) in a future version, we’ll update this page first and clearly disclose what changed. Any networked features would be strictly opt-in.
