Short Story

Librem 5, the phone that focuses on security by design and privacy protection by default. Running Free/Libre and Open Source software and a GNU+Linux Operating System designed to create an open development utopia, rather than the walled gardens from all other phone providers.

A fully standards-based freedom-oriented system, based on Debian and many other upstream projects, has never been done before–we will be the first to seriously attempt this.

The Librem 5 phone will be the world’s first ever IP-native mobile handset, using end-to-end encrypted decentralized communication over the Internet.

Note: This was an “all-or-nothing” campaign, but we crossed well over the $1.5m goal, and will be delivering on the Librem 5 phone. If you would like a Librem 5 you can simply pre-order one of the appropriate rewards now, and we will add you to the shipping queue!

Freedom of Choice

We believe phones should not track you nor exploit your digital life. We are in the middle of a digital rights revolution where you get to decide the future. We at Purism are building a phone that does not run Android nor iOS, but runs PureOS or any GNU/Linux distribution where all the source code is available.

Note that the visual design of the phone is a work in progress and is subject to evolve based on technical requirements and people’s feedback.

Peace of Mind

Our phone will not wholesale gather your data for profit. It will not lock you into an ecosystem that controls you. It will not require you to enter banking details to simply get an app from an app store.

Does Not Track You

Our phone will be built to protect you by default. It will never exploit you for profit. It will be a phone for the people, by the people.

High Quality

We know how to build products that are convenient, privacy and security focused. Our phone will give you peace of mind knowing it does not track you.

What is the Librem 5

The Librem 5 is a 5″ phone that carries with it a social revolution, where we the people can stand up for our digital rights, we can say “We want to control our phone and keep our own data. We refuse to financially back the wholesale gathering of our digital life. We no longer will allow unfettered access to our photos, videos, email, text messages, applications and usage data.” By using a Librem 5 phone you are standing up for the future of phone privacy, you are supporting an open community-driven development environment, where all the source code can be used, re-purposed, and shared to improve society. By backing this campaign, you are voting with your wallet to support a future where people can be protected, feel safe, and participate in a respectful culture.

A No-Carrier Phone?

The Librem 5 can be used in any of three ways:

  1. With a cellular carrier provided phone number, data plan, and WiFi
  2. With a cellular carrier data plan, and WiFi
  3. With no carrier, and using only WiFi

WiFi calling and VoIP calling will be able to be provided in WiFi or data plan modes. With the stretch goal further below, we expect to offer call-out, and call-in with phone numbers in all of these plans as well. If you still require a “traditional” phone number through a carrier and want to make unencrypted phone calls or messaging, it will be an option you can choose, but is not required (we recommend avoiding unencrypted phone calls).

The hardware

Starting with a metal case, high resolution screen, and multifunction port, we heard your feedback, know what you want, since we want it too. The specifications are continuing to get pinned down, and will not be finalized until after the campaign ends, so please share what you’d like to see, and we will evaluate all design feedback that aligns with our beliefs.

The CPU will be an i.MX 6 or i.MX 8, where we can separate the baseband modem from the main CPU, digging deeper and deeper to protect your privacy and isolate components for a strong security hardware stack.

Enabling the path for a true convergence device, capable to work as a phone, making video and audio calls, encrypted messaging, email, web browser, that can also become a full desktop computer with an option for a compatible keyboard, mouse, and monitor. It can be a desktop computer and phone all-in-one.

Linux, GNU, GNOME, GTK, KDE, Plasma, Debian, PureOS, Flatpak, Matrix, HTML5

The software

PureOS will ship by default, an isolation based security focused operating system, where all the source code is available. PureOS, like Ubuntu, Debian, and Red Hat, runs a Linux Kernel and utilizes the GNU operating system tools that power billions of users on a daily basis. PureOS strives for the strictest of security and privacy protection, by releasing all the source code, and offering safe security and privacy defaults, as well as avoiding common security threats, such as ransomware, and data mining tools. PureOS is in complete compliance with FSF’s free distribution guidelines and will never ship non-free binaries.

PureOS on the Librem 5 initially, upon shipment, will offer basic communication services: phone, email, messaging, voice, camera, browsing, and will expand after shipment and over time to more free software applications, through shared collaboration with the developer community (not “read-only open source”, but true free software collaboration).

Decentralized Encrypted Communications

Partnering with Matrix Librem 5 is the first ever Matrix-powered smartphone, natively using end-to-end encrypted decentralised communication in its dialer and messaging app.

Matrix is an open ecosystem for interoperable encrypted communication, supporting a rapidly growing community of over 2 million users for VoIP and Slack-style messaging. Allowing you to easily communicate securely to any Internet connected device, including iOS, Android, Windows, OSX, or GNU+Linux machines. Having a native communication suite which allows for Calling, Text Messaging, Group Messaging, and Video Calling is the future of communication.

HTML5 Apps

Purism’s Librem 5 phone will be able to run HTML5 applications, which means common applications you use everyday will be available through the web browser. Purism will be able to isolate these applications from the OS, so the applications will not be able to have visibility into other running applications or have access to areas that you do not allow.

The plan

After funding is completed, we will prepare the hardware design, manufacture developer units and get those into the hands of all the developers and backers of the development kit, so we can work on the software and full hardware roll-out in parallel. Once we confirm the basics from these developer units, we will update the hardware design and begin production. Learning from experience, we are giving ourselves time to develop and follow the hardware trends to deliver to you the ideal phone product running the most rights-respecting software available.

The product that ships to backers will be finalized phone hardware that can make a phone call, check email, browse the web, make a video call, and take a photo. This is designed to start as an encrypted communication device, and expand, after shipment, over time, to include all the productivity and software common on existing phone and desktop operating systems.

The Librem 5 phone project started a little over 1.5 years prior to the launch of this campaign, researching and selecting hardware that would work to create a PureOS based phone, that would not rely upon Android. We have added team members to do all the research and development, and after testing the hardware to confirm we can meet our goals, we are now at the point of seeking preorders to prove the demand and fund the manufacturing.

We expect to use the funds from this preorder campaign to fabricate the development units, manufacture the phone, port/develop the OS, and develop the communication applications. This is a lot of work to accomplish, and we are both allotting enough time to get this all done, and putting a call out for quality, eager, free software developers to add to our phone development team (see our jobs page for more information).

2018-09-04 update: we initially planned for the phones to ship in Q1 of 2019, but due to an i.MX 8 silicon bug that we need to address before phones are being put into production, we are pushing the production ETA back to Q2 of 2019. You can read more about this in our September 2019 phone hardware report. We thank you for your support, patience and understanding!

After Shipment

After the Librem 5 ships to customers, we will continue to improve the software by adding common and requested applications such as calendar, notes, calculator, pdf viewer, etc. Since this is a free software phone where all the source code and packages are available, we would expect to see developers creating their own applications, porting existing applications, and improving the overall “app store” experience. If you are a developer interested and wanting to port your application, we will be creating a community area to participate in PureOS mobile development. You can find out more about PureOS at

Stretch Goals

Like any great endeavor, we have some lofty goals that could be accomplished with enough funding, so we have included our dream roadmap below. Applying funding targets to each goal, allows us to share the stretch goals and see just how far we can go with the product, based on user support:

$4m = VOIP phone number, call-in, call-out features for Matrix
$6m = Reverse engineering faster WiFi/BT firmware
$8m = Free encrypted VPN tunnel service for all backers for 1 year
$10m = Run Android applications in isolation on Librem 5
$20m = FUN GOAL, Candy Crush (clone) 🙂 available for free
$32m = FUN GOAL, “We did it!”(polite reference to Ubuntu Edge goal)

Ringtone Contest

We want to hear from you, literally! We want to have a unique Purism Librem 5 ringtone, and will give-away (or refund an existing order for) a Librem 5 to the winner(s) of the Ringtone contest!

What we would like is a free format ringtones for; power-on, phone call, text message, video call, and email notification. We will refund any existing order, or give-away a Librem 5 to whomever we select in any of those categories (so yes, it could be one winner, or could be 5).

Please submit your free format sound clips via email with the subject “Ringtone Contest submission”, please provide the files under a free cultural work license, please name the files or reference the file names to the categories mentioned above. (e.g. purism-librem-5_email-at-domain_power-on.flac ).

UPDATE: The ringtone contest is over, we do not accept any further submissions! Thank you all for participating, the results are available here.


Although our core business is hardware, software, and services, and having spent the last 18 months (prior to launching the campaign) doing phone research, there are still risks. We’ve partnered with one of the largest phone manufacturers in the world to produce the case, and fabricate the motherboard from our specifications, and of course sourcing the screen, battery, and power supply. We have a worldwide team to address all that we need; from mainland China manufacturing, Hong Kong exporting, South San Francisco USA assembly, European reseller, and a Worldwide developer network. We’re excited and ready for the journey from this campaign to delivered phone.

One reason for setting the funding goal at our target is to mitigate risk of research and development, and to have some padding for delays, errors, and issues that arise during any new manufacturing project.

Finally, because we will be making some hardware and chipset changes during the development process, this will introduce changes in software or drivers. The good news it that since we believe what you believe, you will end up with a high-quality phone that protects you by default no matter the version of a given chip.


Do I need to add the cost of shipping to my pledge? What about taxes?

We offer free worldwide shipping on orders, so there is no need to add the upfront shipping cost to your preorder (we pay for it).

Please note, however, that shipping insurance, local taxes, customs fees and import duties are still your responsibility as customers. If your shipping address is not in the USA, depending on your country, you may have to pay local import taxes/customs/duty fees, for example; those are imposed by your local government and Purism has no control over this. If you know resellers and distributors in your country that would be interested in working with us to solve this problem, please contact us.

While we cover the initial shipment cost, if you refuse to receive your package after it has shippped (due to duty fees or any other reason, and therefore the carrier sends the package back to us) and you request a reimbursement from us, we will deduct our initial shipping cost (the cost we paid for you as part of the “free shipping”) plus a 10% restocking fee. This includes refused shipments, shipments unclaimed or shipments with issues arising from someone other than original purchaser signature on delivery.

Do you have a German or UK/EU Reseller?

Yes, we have partnered with a German reseller, and will be shipping all German (and hopefully EU orders in general) from Germany.

Can I run Android apps?

Not day 1. However there is a lot of interest in including a isolation layer that will be able to power Android applications natively. We have added that as a stretch goal to quantify the effort.

What forms of payment do you accept?

Credit Card, Direct Bank Transfer, Bitcoin, and International Wire Transfer. If you need any assistance or alternative options for payment, email for assistance.

Do you accept Paypal?

No, Paypal’s policy does not allow for the full funds to be used as pre-sales, they put a large reserve on crowd-funded presales, and that large reserve severely limits the ability for us to pay for non-recurring engineering, tooling, development, manufacturing, and ship product. If you need any assistance or alternative options for payment (or require a one-off Paypal payment), email for assistance.

Will the Librem 5 have CE Markings?

Yes we will have proper and registered CE markings on the Librem 5 phone, the location of those markings will likely be in the lower back section of the case in a light gray silkscreen, similar to our Librem 15 and Librem 13 laptops.

How easy will it be for me to switch from Android or iOS to the Librem 5?

For phone calls, email, web browsing, there will be no issues with switching, if you rely upon native applications that are not yet supported, you may need to use HTML5 applications (Social Media, News, Banking), or consider alternatives (e.g. vs. Signal). If we reach our stretch goal to run Android applications in isolation, it will become possible for some applications to run.

Can I transfer my photos, files, downloads from Android or iOS to the Librem 5?

Yes, you will be able to use the phone as a storage device, that can show up on your computer by just plugging in the USB cable and viewing the folders. This will allow you to import or export files, photos, documents, with ease. With the Librem 5 there is no proprietary software that locks your files into proprietary formats, allowing easy sharing of the content you want to share.

Will I be able to communicate from my Librem 5 to other phones?

Yes, you will be able to make regular unencrypted phone calls to any phone number. You will also be able to communicate securely by using the phone dialing application and messaging application, that can run on the Librem 5 phone, Android based phones, and iOS based phones, and any computing device.

Will communicating from my Librem 5 to other phones compromise my privacy or security?

The Librem 5 will be the most secure when communicating with another Librem 5 phone, communicating via an encrypted app on a Librem 5 to an Android or iOS encrypted app is the second best option available.

Will my existing SIM card work? What countries and networks will be supported?

The Librem 5 is an open network phone, not locked to any particular network.
We aim to support 3G and 4G for the most common international frequency bands and carriers, with an interchangeable module. Exact specifications will follow as we are evaluating the data+voice modems that will be used.
We expect it to work on 3G and 4G networks, and hope for it to also work for GSM, UMTS, or LTE-based network services.

Will I be able to use emergency services (e.g. 911 or 999)?

Using the 3G/4G data+voice modem, the Librem 5 will work with most carriers; the carriers are the ones providing technological support for emergency services dialing.

Are all hardware components running completely free software, with the source code available?

From testing the CPU, GPU, Bootloader and all software will run free software, we are evaluating the WiFi and Bluetooth chips and firmware, this is an area we have to evaluate, finalize, and test. The mobile baseband will most likely use ROM loaded firmware, but a free software kernel driver. We intend to invest time and money toward freeing any non-free firmware.

Can the Librem 5 phone run Windows?

Very likely, even though we will not expend resources to test this.

Can the Librem 5 phone run Android?

Very likely, even though we will not expend resources to test this.

Can the Librem 5 phone run iOS?

Not likely, and we will not expend resources to test this.

Will the phone receive updates after launch?

Yes, all hardware Purism releases gets regular security and performance updates within PureOS.

Can the phone runs Qubes OS like Librem laptops?

No, Qubes OS requires virtualization on the CPU, and the Librem 5’s CPU will not offer that. The Librem laptops do support VT-d and VT-x and therefore support running Qubes OS.

What if you don’t reach the funding target?

It will show that there is not enough interest in producing a device that focuses on security, privacy, and digital rights, which will be a tremendous social disappointment. If we don’t reach our target then all contributions will be fully refunded.

Will Twitter, Fandango, My Bank, etc. work on a Librem 5 phone?

Yes, any web based app will work through the browser. Over time these sites will either use progressive web applications, or could have a native app.

Will you have a calendar app, maps app, notepad app, etc. by default?

Our first version will be focusing on phone calling, encrypted online communication, and web browsing. However the free software community is encouraged to test, port, author, and get involved to take all the great free software applications that exist already and make it work on a 5″ screen.

Will I be able to open word or excel documents sent via email?

At delivery we do not plan to support the reader or renderer for these proprietary formats, but this is a top priority to solve after product delivery.

Will there be hardware kill switches?

Yes, we need to evaluate the wiring and design limitations to determine the best approach; the intention is to include Camera, Microphone, WiFi/Bluetooth, and Baseband Modem kill switches or some combination. We may utilize a microphone headphone jack plug to kill the microphone at the hardware level as an example of some inventions we are testing and considering. But rest assured we will have hardware kill switches.

Can I remove the battery and replace it?

Yes, like all Purism products, the case itself will allow you to access the insides, and the battery will be modular and can be replaced with ease.

Does Purism comply with CALEA requirements?

No, because CALEA applies to US based telecommunications providers, not to Purism. If the user of a Librem 5 phone uses a carrier in the US with a traditional “phone number”, that carrier must comply with CALEA for phone calls, as the phone call is sent over the carrier’s connection. Pure Matrix-to-Matrix calls are outside of CALEA requirements (Matrix nor Purism are telecommunications service providers). If the call touches the PSTN is becomes the carrier’s responsibility to adhere to CALEA. Matrix is an encrypted VoIP/messaging protocol not a telco.

Will this run coreboot and have the Intel ME neutralized?

The Librem 5 will not be Intel based, it will be i.MX 6/8 based, so therefore we don’t need coreboot nor the Management Engine. The i.MX 6/8 CPU will be completely free software without any binaries whatsoever!

Why don’t you build a free UI ontop of Mer (Sailfish OS)? Or resurrect Firefox OS? Or insert-name-here?

Because we want to promote a pure and unified stack, not have a separate mobile OS with proprietary bits or a completely different middleware stack. We want to support the community efforts of GNOME, KDE and UBPorts, and allow for any GNU+Linux to work out-of-the-box providing mainline improvements that work not just on mobile but across the device spectrum. The Librem 5 is a new approach to use a regular Linux system and adopt it to mobile use-cases instead of creating a completely new system. We do not create a walled garden, instead we tear down these walls, creating an open utopia. A fully standards-based freedom-oriented system, based on Debian and many other upstream projects, has never been done before–we will be the first to seriously attempt this.

You can also learn more about our position on GNOME and KDE further below in this FAQ.

Will the Librem 5 be able to run Anbox or Shashlik?

We will test the capabilities of powering Anbox or Shashlik to allow users the ability to run Android applications within PureOS on the Librem 5, but our long-term goal is to utilize native applications that adhere to our strict philosophy. Enterprise clients or users who require Android applications may choose to to run a Android applications within an isolation container, so this is the reason for testing this type of configuration. We have a stretch goal to help with this developmental effort to have Android apps run in isolation.

What hardware specifications are subject to change?

RAM, Storage, USB version and type, WiFi version, Bluetooth version, Screen type, Screen resolution are the important things that are subject to change based on supplier availability, and software and driver support.

What is the RAM/Drive configuration?

Purism plans to max-out the CPU’s RAM and Drive according to the best capabilities during testing, and have listed the minimum confirmed specifications on the campaign page.

What detailed hardware specs can be provided, and when?

The detailed specifications will be released as we firm up the hardware choices, it will be ongoing communication during the research phase.

What CPU will be used, i.MX 6 or i.MX 8?

We started prototyping with the i.MX 6, and are getting close to be able to fully confirm the possibility of using i.MX 8. We want to know we can use i.MX 8 for sure. The i.MX8 would be pretty ideal for us, it has much more computational power while at the same time reducing power consumption since it uses a more recent production technology. It is especially designed for mobile use. The i.MX 8M or i.MX 8X seem like the ones we would want. But they have two areas we will be closely following; we will be getting new prototypes in May-June 2018. The i.MX 8 will have a new, more recent GPU, a dual core Vivante GC7000Lite which is not yet supported by the free Etnaviv driver. The big questions are, when will silicon become available and when will decent Linux support be available for it? So we will keep evaluating after the campaign ends and decide i.MX 6 or do we get to fully move to i.MX 8.

What warranties apply to the Librem 5 phone?

Our standard 1yr parts and labor warranty applies. Also if you are not happy with the product, you may return it within 30 days of receiving it for a full refund. Purism will not cover the cost of return postage and packaging.

Will this be an “open hardware” design?

Our intention is to have everything freed down to the schematic level, but have not cleared all design, patents, legal, and contractual details. We will continue to advance toward this goal as it aligns with our long-term beliefs.

Why not use Wire, Telegram, WhatsApp, or Signal?

While these all provide encryption, and some do release the client software under acceptable licensing terms, they all are walled gardens wanting you to register with them, and their server software is proprietary and therefore not acceptable to us. Matrix is the proper solution and that is why we have partnered with them.

Will you be seeking FSF RYF endorsement?

We will constantly keep FSF up-to-date on the hardware and software, our current understanding is any non-free kernel firmware needed for RF chips will not meet the RYF qualifications today, so we will continue to evaluate the WiFi and Bluetooth cards in the hopes to advance toward RYF. The end goal for us is to gain RYF for all Purism products. PureOS will always be compliant with FSF distribution endorsement, PureOS will never ship with non-free binaries.

Will you be running GNOME, Plasma, or your own custom UI?

We will be working with GNOME/GTK, KDE/Plasma and Ubuntu Touch communities, and have partnered with the foundations behind them for the middleware layer. PureOS currently is GNOME-based and look forward to working with GNOME as an upstream as well as GNOME’s OS and design-centric development model; however we will also test, support, and develop with KDE and the KDE community, and of course we will support Qt for application development.

Learn more about the rationale behind this approach (part 1 and part 2).

Will the phone have a fingerprint reader, or other biometric access?

No, we will not be shipping with any biometric hardware, the reasons for this is because single access via biometrics does not prevent access to your phone the same way a security code or lock does. The US Supreme Court has alluded to biometric access not protecting you the same way that a security code from memory (a security code) does (e.g. You can say “no” to a passphrase, or security code, but you cannot say “no” to biometric (physical) information). So even if in future models of the Librem 5 phone we do include biometric hardware, we will be double-locking it with a security code, to have the best security story we can for users.

Can I come work for you?

Please visit and take a look. We are mostly interested in eager, self motivated, free software enthusiasts who want to change the world for the better.

Can I invest in Purism?

Yes, please reach out to (Investor Relations), and you will get a reply within 24 hours to discuss the opportunity.

I don’t see my question, how can I get it answered?

Please email and we will answer you, and if it applies to the general audience we will post it here!

    i.MX8M likely CPU, read why...

    The Librem 5 crowdfunding campaign is still cranking along nicely, while it is going on we wanted to provide a progress report on the hardware selection as well as the advancements with our existing development boards. The hardware is working; i.MX8M; Etnaviv; full HD, are the likely hardware candidates for the Librem 5 phone.

    50%, $750,000 crossed

    Halfway in dollars needed and nearly halfway in days is a remarkable accomplishment for crowdfunding, and we expect the momentum to steadily grow as we approach $1,000,000!

    $250,000 crossed, a major milestone!

    Crossing the $250,000 mark is a tremendous milestone! Thank you for all the support, and getting the word out. We will update with more exciting news in the coming days!

    $200,000 and counting!

    The phone campaign is off to a great start! We have recently crossed the $200,000 milestone shortly after the beginning of the campaign. Crowdfunding is always a matter of shared interest and momentum, which often leads to interesting situations. In this case, if all the people who filled out our phone survey a few months ago backed the $599 Librem 5, we would cross the $1.5 million mark immediately. From past experience, and the way crowdfunding works, we are way ahead of the expected trend line to succeed. From discussing with supporters, it seems many have been waiting to see if the campaign is going to get to 100% before committing, which is probably a communication mistake on our part, as the campaign is a no-risk, all-or-nothing campaign: if you back the campaign using a credit card, we only pre-authorize your card; we will not (and cannot) charge your card until we cross the goal. Which means, you get to show your support early and get all the other "wait-and-see" folks to pile on! Feel free to back this campaign now (and pay later). Be the change you want to see!

    All-or-nothing funding

    Since the question arose a few times, we wanted to update that this Librem 5 campaign is a no-risk, all-or-nothing, campaign. Which means we will only pre-authorize credit cards and upon the campaign reaching $1.5m we will then charge the cards. This makes it easy to back the campaign early, and pay later.

    $150,000, 10% in fewer than 6 days

    With sustained momentum we have crossed a critical threshold of 10% in under 6 days, this is superb growth to advance past this most critical percentage. 10% in such a short period shows there is a lot of interest in the Librem 5! Now we need to spread the word further to keep this going! Keep up the great work everybody!
