Backblaze Policies

Backblaze Privacy Notice

Last updated: July 10, 2018

We value your business and we know your privacy is important to you. Accordingly, we have implemented this Privacy Notice which describes: how we collect and use personal information that you provide to us when you create a Backblaze account, via our website or Apps; what we do with the information collected; and how you can exercise your privacy rights.

This Privacy Notice applies only to the information collected in respect of your account and does not apply to the content that customers store on our system, including any personal information. Backblaze will not disclose, move, access or use customer content except as provided in Backblaze's terms and conditions, and our data processing addendum.

Who we are

Backblaze is a US headquartered data storage provider that offers two different products:
  • Computer Backup, which provides unlimited cloud backup for individuals and organizations using Macs or PCs (laptops and desktops); and
  • B2 Cloud Storage, which provides low-cost cloud storage for individuals and organizations.

What personal information do we collect?

Information you provide to us
When requesting to use Backblaze's services we may ask you to provide personal information to us. For example, when you create a Backblaze account, we will ask you for your email address and a password. We may also ask for your phone number for purposes such as two-factor verification or for sending you service alerts. If you choose to sign up for one of Backblaze's services, we will ask you for billing information. To order a physical item from us, such as a Restore by Mail, we will ask for shipping details. At times we may ask for other information such as your name or the name of your company name.

During your interaction with Backblaze, you may choose to provide us with personal information when you email us, chat with us, answer a survey, comment on our blog, or communicate with us through social media services like Twitter or Facebook.

If you refer a friend to Backblaze, we will ask you for their email address. Backblaze will then contact your referred friend to determine whether your friend consents to us contacting them.
Information that we collect automatically
Our Computer Backup service automatically backs up your files to Backblaze; B2 Cloud Storage allows you to upload your files to our service. While the content of your files may include personally identifiable information, both in the content of a file and in metadata, this Privacy Notice, as stated at the outset, only applies to the information collected in respect of your account and not to the content that you store on our system.

When you use any Backblaze product we may collect certain information automatically from and about your device. This includes data about your software, the operating system you use when accessing our service, your Internet Protocol address and the date and time of each request you make to Backblaze. When you use our backup services, we will also receive information such as the names of external drives, file types transferred, and number and size of files transferred.

Collecting this information enables us to better diagnose problems with our products, provide customer support more effectively, inform you about operating systems we no longer support as well as ensure the continuous functionality of our products.
Information that we collect from third parties
We may collect additional information about you from third parties primarily to assist us in understanding how we can maintain and improve the services we offer to better serve you. Third party tools that we use for this are from: Optimizely, which records a user's clicks and enables Backblaze to test different versions of its website; HotJar, which is used to record where people move their mouse on key web pages; and Google Analytics which informs Backblaze about page visits which in turn allows Backblaze to decide if it needs to update certain pages. SurveyMonkey, which Backblaze uses to distribute surveys, which users can voluntarily complete, will collect a user's IP address.

What we do with your personal information

Under no circumstances do we rent, trade or share your address or e-mail address with any other company for their marketing purposes without your consent. We may use the information we collect through our products for a number of reasons, including to:
  • provide, operate, optimize and maintain our online platforms, products and services;
  • understand how you use our products and customize your experience;
  • set up online accounts;
  • process, fulfill and provide any updates on online orders;
  • send you marketing communications we think you'll find valuable, where it is in accordance with your preferences;
  • provide customer support via online chat services; deal with your online enquiries and requests sent by email; and provide you with information and access to resources or services that you have requested from us;
  • improve the layout, navigation and content of our online products;
  • identify any server problems or other IT or network issues;
  • prevent abuse of the products and services we offer; and
  • carry out other legitimate business purposes, such as to improve our products and services, as well as other lawful purposes about which we will notify our users and clients.
Email Communications
From time to time, Backblaze will communicate with you via email. There are two types of email you may receive:
  1. Service Emails: These are service related emails such as confirmation of password change, expiration of credit card, or a reply to a support issue. You cannot opt out of receiving these messages as they are part of the service which Backblaze provides to you. You can manage certain Service Emails by signing in to your Account. To stop receiving all Service Emails, you must cancel the service and uninstall the Backblaze software from your devices.
  2. Marketing Emails: These will include Backblaze company news, tips-and-tricks, service promotions (e.g., refer-a-friend) and similar types of material. Upon creating a Backblaze Account you will be able to manage your email preferences, including opting out of receiving all Marketing Emails. You will also be able to unsubscribe at any time by using the unsubscribe link provided in any given email.

We will only process personal information in ways that are compatible with the purpose we collected it for or for the purposes you later authorise. Before we use your personal information for a purpose that is materially different than the purpose we collected it for or that you later authorised, we will provide you with the opportunity to opt-out.

Who we share your information with

We may share and disclose your personally identifiable information only in the limited circumstances described below:
  • To vendors and other third party service providers who require access to your personal information to assist in providing and improving our products. The third parties that access and use your information only on our behalf include companies such as Stripe, Salesforce, Google Analytics, Freshbooks, Facebook, Twitter, Hubspot, MailChimp, Plivo, Slack, SurveyMonkey, SendGrid, Twillio, and ZenDesk. For example, we partner with Stripe and Freshbooks to assist us in processing your payment; Hubspot enables us to send you marketing emails, subject to your preferences; SendGrid is used to communicate service emails to you; Twillio and Plivo are used to send SMS messages to you when you use our 2-factor authentication feature; and Zendesk is used to facilitate our customer support and online Chat service.

  • B2 Cloud Storage users can give third parties the ability to access information and content in their account (e.g., through APIs). When other services access and use your information, their conduct is governed by their own terms and policies.
  • The settings for B2 Cloud Storage also give you the option to make information and content available to other people.
  • We may disclose aggregate, non-identifying information about how our users use Backblaze products.

Legal basis for processing your personal information
(EEA visitors/customers only)

If you are a visitor/customer located in the European Economic Area ("EEA"), our legal basis for collecting and using the personal information described above will depend on the personal information concerned and the specific context in which we collect it.

In some cases, we may also have a legal obligation to collect personal information from you.

If we ask you to provide personal information to comply with a legal requirement or to enter into a contract with you, we will make this clear at the relevant time and advise you whether the provision of your personal information is mandatory or not (as well as of the possible consequences if you do not provide your personal information). Similarly, if we collect and use your personal information in reliance on our legitimate business interests, we will make clear to you at the relevant time what those legitimate business interests are.

Backblaze has certified adherence to and commits to apply the Privacy Shield Principles to all personal information it processes in reliance on the Shield.

If we have received your personal information in the U.S. and subsequently transfer it to a third-party agent or service provider for processing, and such third party agent or service provider processes your personal information in a manner inconsistent with the Privacy Shield Principles, we remain responsible under the Privacy Shield unless we can prove we are not responsible for the event giving rise to the damage.

You can direct any questions or complaints about the use or disclosure of your personal information to us at We will investigate and resolve any complaints or disputes regarding the use of personal information within forty-five (45) days of receiving your complaint.

How we protect your information

The security of your personal information is very important to us.

When you enter personal information such as a credit card number on our website or via our App we encrypt that information using secure socket layer technology (SSL). For purchases made online with credit cards, we receive your credit card number in encrypted form, and transfer it to our credit card processor, Stripe, for processing. Our employees do not have access to this information. We do not store PIN data or 3-digit security codes.

We use appropriate technical and organizational security measures to protect your personal information from loss, misuse, and unauthorized access, disclosure, alteration and destruction, both during transmission and once we receive it. However, no method of transmission over the Internet, or method of electronic storage, is 100% secure. Therefore we cannot guarantee its absolute security.

Your data protection rights & choices

  • If you wish to access your personal information that Backblaze collects, you can do so at any time by contacting us using the contact details provided under 'How to contact us' heading below.

  • If you are a resident of the EEA, you can object to processing of your personal information, ask us to restrict processing of your personal information or request portability of your personal information where it is technically possible. Again, you can exercise these rights by contacting us using the contact details below.
  • Similarly, if we have collected and processed your personal information with your consent, then you can withdraw your consent at any time. Withdrawing your consent will not affect the lawfulness of any processing we conducted prior to your withdrawal, nor will it affect processing of your personal information conducted in reliance on lawful processing grounds other than consent.
  • You have the right to complain to a data protection authority about our collection and use of your personal information. Contact details for data protection authorities in the EEA, Switzerland and certain non-European countries (including the U.S. and Canada) are available here.)

We respond to all requests we receive from individuals wishing to exercise their data protection rights in accordance with applicable data protection laws.

Data retention

We will retain your personal information for the period necessary to fulfil the purposes outlined in this Privacy Notice unless a longer retention period is required or permitted by law, for legal, tax or regulatory reasons, or other lawful purposes.

When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize it or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.
