Privacy
Understand what stays in your browser and what a network-assisted feature may share.
Paperlane's local tools are built to process your documents entirely on your device. This page explains exactly what that means, when a feature departs from that default, and what you can check for yourself.
Local processing by default#
Local PDF tools read the bytes of the file you select and process them inside your browser tab using WebAssembly and JavaScript. The document is never uploaded to a Paperlane server as part of a local tool's run.
Closing the tab, navigating away, or reloading the page clears the active file selection and any in-memory working copy. Nothing is retained server-side because nothing was sent there.
Network-assisted features#
A small number of features (for example AI-assisted summarization or chat) require sending extracted text or page content to a model provider to produce a result. Any such feature is labeled before you use it and will not run until you take an explicit action to start it.
We do not silently upgrade a local tool into a network call. If a feature's behavior changes to require a network round-trip, that is treated as a distinct, clearly labeled feature rather than a variant of the local one.
What we collect#
Standard, privacy-respecting web analytics (page views, coarse timing, error rates) may be collected to keep the app reliable. This does not include document content, filenames, or extracted text.
We do not build advertising profiles from document content, and we do not sell document data.
Your controls#
You can inspect network activity yourself using your browser's developer tools while running a local tool — you should see no outbound request carrying your file's bytes.
If you find a local tool that behaves differently from what this page describes, please report it through the Contact page so it can be verified and fixed.
