IPFS Companion Privacy Policy

First Posted: 2019-02-15
Last Update: 2023-01-27
(change history)

This Privacy Policy governs the use of the IPFS Companion browser extension offered by Protocol Labs, Inc. (“IPFS Companion” or the “Service”).

The Service is offered subject to your acceptance without modification of all the terms and conditions herein, and all other other operating rules, policies and procedures that may be updated from time to time. By accessing or using any part of the Service, you agree to be bound by the terms and conditions of the Privacy Policy. If you do not agree to all of the terms and conditions of this Privacy Policy, then you may not access the Service.

Personal Information

We do not collect personal information from the users of the Service.


We collect non-user-specific metrics via the Service. For more information on how to change your preferences with respect to the metrics, please contact us via methods mentioned below.

Additional Privacy Considerations

If you add files to the IPFS Network using the IPFS Companion extension, they will be stored on your local IPFS Network node. Those files are also then cached by anyone who retrieves those files from the IPFS network and co-hosted on that user’s local IPFS Network node. Generally, cached files will eventually expire, but it’s possible for a user with whom you have shared access to such files (by sharing the relevant Content Identifier or CID) to pin that data, which means the cached files then will not expire and will remain stored on such user’s local IPFS Network node. All content shared with the IPFS Network is public by default. This means your files and data that you’ve added will be accessible to everyone who knows the CID or queries the data on the IPFS Network. If you want to share certain materials or data privately, you must encrypt such data before adding it to the IPFS Network.

If you are using “Linkify IPFS Addresses” or “Catch Unhandled IPFS Protocols” experiments, websites will be able to detect you are running IPFS Companion. This behavior can be changed on the Preferences screen by disabling mentioned experiments.

If you are using DNSLink (its lookup is enabled by default), then the IPFS node will be executing DNS queries for all domain names visited during browsing, and those queries will use a DNS resolver configured in your operating system. To disable this behavior, set "DNSLink lookup" to "Off" in Preferences.
