Privacy and your data

What Lark stores

For each link you save, Lark keeps the address, the page's title and text as they were when you saved it, the summary and tags it generated, the collection it filed the link in, and any notes or reminders you added. Feeds you subscribe to and the posts they deliver are stored the same way.

Taking your data with you

Everything can be exported from Settings → Backups as JSON, CSV, or HTML. The JSON backup is complete and can be restored into Lark; the HTML export is the format other browsers and apps import.

The browser extension

The extension sends Lark only what it needs to save pages and check whether a page is already saved. Privacy and data in the extension guides lists it item by item.

Deleting your data

Settings → Data deletes your saved links and everything Lark generated from them. Cancelling a subscription does not delete anything; deletion is always a separate, deliberate step.
