What personal information do we collect?
Contact and account information: We collect the information you provide to us, such as your name, avatar picture, email address, and social media handles. Note: Keybase never requires a phone number and no longer requires an email address in order to open and maintain an account.
Team names and membership: If you create or join a team on Keybase, we collect and store the names of the teams and subteams, their membership, and when they were formed.
Hashed password: We collect and store information about your Keybase password that allows you to prove you know your password; that “stretched” password is sent to Keybase’s servers. See here for more information.
Account activity: We collect information about your activity while using the Services, such as proving you control a certain Twitter username, announcing your public key, editing your biographical information, or editing any of your social media usernames. Some of this information is aggregated, summarized, and published into the Bitcoin blockchain in order to detect and guard against certain vulnerabilities. See “Disclosures to your signature chain, the Merkle tree, and the Bitcoin blockchain” below for information on how we treat this data.
Files and Data. We collect and store files and information that you transmit to other parties using Keybase or that you elect to store on the Services. This data is always encrypted on our servers, except for documents in your public folder and your public chats. Those are not encrypted because you choose to make those publicly accessible.
Do Not Track. Keybase does not collect personally identifiable information from you to track you across third-party websites. As a result, Keybase does not specifically respond to web browser Do Not Track signals.
Unique personal identifiers. We collect and store information to identify you, such as your Keybase user ID and your IP address (which is stored only temporarily).
Network usage and activity. We collect certain technical and analytics data, for example the type of device you’re using to access our Services or the operating system you’re running. Keybase is designed to store the minimum amount of technical data for the shortest time necessary in order for you to have the Services across all the devices you add.
Interactions with us: If you email us, we may keep the content of your message, your email address, and your contact information to respond to the request and otherwise follow up as necessary.
