Privacy policy for Lightpile

Last updated: 11 November 2026

Lightpile is a Chrome extension that gathers the posts you saved on X, TikTok, Instagram and Facebook into one list in your browser, so you can sort them. It has no account and no server. Nothing about your saves leaves your computer.

What Lightpile stores

Only for the apps you connect, and only from their saved lists (X bookmarks and bookmark folders, TikTok favourites and collections, Instagram saved posts and collections, Facebook saved items and lists):

• for each save: its link, its caption (up to 1,000 characters), the author’s name or handle, the post date, the kind of post, the link to its thumbnail, the names of the folders it is in, whether the post still exists, when it was last seen in your saved list, and whether it has left that list;
• what you decide about each save (Do it, Keep or Let go), when you decided, and whether you ticked it done;
• the topic of each save, and the topic rules you changed;
• for each app: whether it is connected, when it was last read, how many saves were read, and the last error, if any, with its error code (such as “signed out”) and the app’s answer code (such as 401);
• for Diagnostics, a log of each app’s last 40 update steps: when an update started and ended, whether it ran in an open or a background tab and whether that tab was on the saved page, how many pages and saves it read and how long they took, retries, and error codes. The log holds no captions, names, folder names or links;
• the dates Lightpile was installed and last updated, and the name of the last AI topics error, if any;
• your Instagram username, used only to open your own Saved page to read your collections;
• your settings, such as whether AI topics are on.

Lightpile does not store or read your passwords, sign-in cookies, messages, feed, followers or browsing history.

Where it is stored

In the extension’s own storage in this browser profile, on your computer (IndexedDB and Chrome’s session storage, which is cleared when Chrome closes). Lightpile does not use Chrome sync storage, so nothing is copied to Google’s servers or to any other server.

How it is used

• To show your saves in one list, let you sort them, search them and export them.
• To read new saves when you click Update, or when you visit a connected app (at most every six hours, to show how many new saves are waiting).
• When you open your saved list on a connected app yourself, the saves it shows are added to your list too.
• When you open the toolbar panel, Lightpile reads the address of the tab you’re on, to show that app’s saves or, on other sites, the site’s name. The address isn’t stored.

Network requests

Lightpile talks only to the four apps you connect, from a tab of that app, with the session you already have there, to read your own saved list. To do that it repeats the app’s own request from inside your tab, with the same headers the app’s page sent; those headers stay in that page’s memory and are never stored or sent anywhere else.

Thumbnails load from the app the post came from, as they would on the site. When you play a preview in the Library, it loads in a frame from www.tiktok.com, www.instagram.com or platform.twitter.com, which receives that post’s address or ID, as an embedded post on any website would. Lightpile has no analytics, no tracking and no server of its own.

On-device AI

If you turn on AI topics, Lightpile asks the AI model built into Chrome to pick a topic for each save. The model runs on your computer, and captions are not sent anywhere. Chrome downloads the model once, only after you turn the feature on. See Google’s terms for Chrome’s built-in AI.

Sharing

Lightpile does not sell, share or transfer your data to anyone. Files leave the extension only when you export or back up, and they are saved where you choose. The diagnostics report, which you copy yourself, holds each app’s status, counts, timings and error codes, the recent update log described above, and the versions of Lightpile, Chrome and your operating system. It holds nothing about your saves: no captions, names, folder names or links.

Limited Use

Lightpile’s use of the information it handles complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.

Keeping and deleting

Your data stays until you delete it. In Settings, Delete everything removes every save, decision and setting and disconnects all apps. You can also remove single saves in the Library. Removing the extension from Chrome deletes all of its storage.

Changes to this policy

If what Lightpile stores or sends ever changes, this policy will be updated before the release that changes it, and the update will be described in the release notes.
