Terms of Service

last updated · july 19, 2026 effective · upon installation or use
The short version: Pace Browser is free, proprietary software. You may install and use it on your own Windows devices; you may not copy, resell, or reverse-engineer it. Your data stays on your device, addons and websites are your responsibility to vet, and the software is provided as-is. The details — all of them — are below.

01Acceptance of these Terms

These Terms of Service ("Terms") are a legal agreement between you and That1Dev ("we", "us", "our") governing your download, installation, and use of the Pace Browser desktop application and the first-party services at https://pace.that1dev.com, including the website, Addon Shop, release service, and optional PaceSync relay (together, the "Software").

By downloading, installing, or using the Software, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, do not install or use the Software, and uninstall it if already installed.

If you are using the Software on behalf of an organization, you represent that you have authority to bind that organization to these Terms, and "you" refers to both you and the organization.

02Definitions

  • "Pace Browser" or "the browser" — the Chromium-based desktop web browser for Windows developed and distributed by That1Dev.
  • "Pace Addon" — a browser extension built in Pace's native addon format (an addon.json manifest with optional scripts, styles, and block rules).
  • "Addon Shop" — the official catalog of Pace Addons at https://pace.that1dev.com/paceaddons, accessible from pace://extensions inside the browser. Listings may be Verified or unverified.
  • "Fast Mode" — the optional feature that pre-loads pages as you type in the address bar.
  • "Theme" — a visual customization package (.pacetheme file) that restyles the browser's interface.
  • "Content" — any website, media, file, extension, theme, or other material accessed through the browser.

03The Software

Pace Browser is proprietary, closed-source software. It is offered free of charge, but it is not open source and it is not in the public domain. The source repository is private. Public installers, update metadata, and documentation are distributed from https://pace.that1dev.com; access to those materials does not grant any license to use, copy, modify, build, or redistribute the source code.

The browser is built on Chromium and Electron technologies, which include open-source components licensed under their own terms. Applicable open-source notices are available at pace://tos inside the browser and in the application's license documentation. Nothing in these Terms limits any rights you hold under those third-party open-source licenses with respect to those components.

04License grant

Subject to your compliance with these Terms, That1Dev grants you a limited, personal, revocable, non-exclusive, non-transferable, non-sublicensable license to:

  • download and install Pace Browser on Windows devices that you own or control; and
  • use the browser for personal purposes and for ordinary workplace browsing.

This license does not sell the Software or any rights in it to you. We retain all rights, title, and interest in the Software that are not expressly granted here.

05License restrictions

Except to the extent a restriction is prohibited by applicable law, you agree that you will not, and will not permit anyone else to:

  • copy, redistribute, or republish the Software or its installer, whether or not for a fee (link to the official download page instead);
  • sell, rent, lease, sublicense, or otherwise commercialize the Software itself;
  • modify, adapt, translate, or create derivative works of the Software;
  • reverse-engineer, decompile, or disassemble the Software or attempt to extract its source code, except where and only to the extent applicable law expressly permits it despite this restriction;
  • remove or alter any proprietary notices, branding, or license information in the Software;
  • bypass or interfere with security features of the Software, including the addon security warnings, the DRM components, or update integrity checks;
  • misrepresent modified or repackaged software as Pace Browser or as endorsed by That1Dev.

06Intellectual property

The Software — including its code, design, user interface, icons, logo, the "Pace" and "Pace Browser" names, and the bundled themes — is owned by That1Dev and protected by copyright and other intellectual-property laws. You may not use the Pace name or logo in a way that suggests affiliation with or endorsement by That1Dev without prior written permission, except for truthful, nominative references (for example, "works with Pace Browser").

Chromium, Google Chrome, and the Chrome Web Store are trademarks of their respective owners. Pace Browser is not affiliated with, sponsored by, or endorsed by Google.

07Eligibility

You must be at least 13 years old, or the minimum age of digital consent in your jurisdiction if higher, to use the Software. By using it, you represent that you meet this requirement. If you are under the age of majority where you live, you should review these Terms with a parent or guardian.

08Acceptable use

The browser is a tool; what you do with it is your responsibility. You agree not to use the Software to:

  • violate any applicable law or regulation;
  • infringe the intellectual-property, privacy, or other rights of any person;
  • access systems, accounts, or data you are not authorized to access;
  • create, distribute, or operate malware, phishing pages, or other harmful code — including malicious Pace Addons;
  • harass, defraud, or harm others; or
  • circumvent technological protection measures on third-party content, except as permitted by law.

You are solely responsible for the websites you visit, the Content you access, the addons and themes you install, and everything you download through the browser.

09Fast Mode

When Fast Mode is enabled, the browser pre-loads websites as you type in the address bar. This means network requests may be sent to websites before you press Enter, including to sites you ultimately do not visit. Those requests originate from your device and IP address and are visible to the destination servers like any other visit. You can turn Fast Mode off at any time in pace://settings under Performance. See the Privacy Policy for full details on how Fast Mode behaves on the network.

10Pace Addons & the Addon Shop

Pace Browser uses its own native addon format, the Pace Addon. It does not run Chrome extensions. Addons can be installed from the official Addon Shop or loaded manually from a folder or file.

The Addon Shop

Publishing a listing does not mean Pace reviewed or endorsed it. An unverified listing has not completed Pace's manual safety review. A Verified badge means we reviewed the exact package version and cryptographic digest identified by the Shop. It is a good-faith screening for obvious safety problems, not a guarantee that an addon is free of defects, security issues, deceptive behavior, or unwanted behavior. A changed package loses its Verified status until that new package is reviewed.

Addons from outside the Shop

Addons installed from outside the official Shop display a security warning before installation. Installing them is entirely at your own risk. An addon's content scripts run inside the pages it matches and can read and modify those pages, including anything displayed on them. Only install addons from developers you trust, and review the permissions declared in the addon's manifest.

Our rights

To protect users, we may update the browser to disable or block addons that we reasonably believe are malicious, deceptive, or harmful, whether installed from the Shop or elsewhere.

11Building and distributing addons

If you build Pace Addons, you are the developer of that addon and solely responsible for it, including its behavior, its compliance with law, and any privacy disclosures it requires. By submitting an addon to the Addon Shop, you grant us a non-exclusive, worldwide, royalty-free license to host, review, distribute, and display the addon and its listing materials for the purpose of operating the Shop. You represent that you have all rights necessary to grant this license and that your addon does not violate Section 8 (Acceptable use).

Addon Shop developer accounts

Publishing or managing a listing requires a separate Addon Shop developer account. You must provide accurate account information, protect your password and optional two-factor credentials, and promptly notify us if you believe the account is compromised. You authorize us to process the account, publisher, package, verification, security, and request metadata described in the Privacy Policy. We may suspend an account or listing to investigate abuse, security risk, infringement, fraud, or a violation of these Terms.

$5 safety verification

A developer may purchase a $5 manual safety review for one immutable addon version and package digest. The payment purchases review work and does not guarantee approval, endorsement, a Verified badge, a particular completion time, or permanent Verified status. If the package is rejected, we provide feedback about changes needed for that submitted package. Updating or replacing the package requires a new review. Checkout is processed by Lemon Squeezy under its terms and privacy policy; any taxes, refunds, or payment disputes are handled according to the terms shown at checkout and applicable law.

12Password manager

The browser includes an optional built-in password manager. Saved credentials are encrypted on your device, and their plaintext is never transmitted to That1Dev or any third party.

If you enable PaceSync, encrypted vault records may be wrapped in an additional end-to-end encrypted sync envelope and routed to your paired devices. The PaceSync relay does not receive your master password, plaintext credentials, or decryption keys, but it may process ciphertext and ordinary delivery metadata as described in the Privacy Policy.

Your master password is the only key to your saved credentials. It is never stored — anywhere — and it never leaves your device. Consequently:

  • If you lose your master password, your saved passwords cannot be recovered — not by you, not by us, not by anyone.
  • You are responsible for remembering your master password and for keeping independent access to your important accounts (for example, through the account provider's own recovery options).

That1Dev is not liable for any loss of credentials, loss of access to accounts, or any consequences arising from your use of, or inability to use, the password manager. Use of this feature is at your own risk.

13Themes

Themes change the browser's appearance only. Bundled themes are part of the Software and covered by Section 4's license. Themes obtained from third parties (including .pacetheme files shared by other users) are third-party content you install at your own risk, though themes cannot run code or access page content.

14Streaming & DRM

Pace Browser includes the Widevine Content Decryption Module ("Widevine CDM") so that DRM-protected streaming services work in the browser. You acknowledge that:

  • the Widevine CDM is third-party technology licensed from its owners and provided through the castLabs Electron distribution, and its use may be subject to its own license terms;
  • when you play DRM-protected content, the CDM communicates with third-party license and provisioning servers as described in the Privacy Policy;
  • we do not control which streaming services work, what content they offer, what playback quality they permit in third-party browsers, or whether they continue to support the browser; and
  • your use of any streaming service remains governed by that service's own terms and subscription requirements.

15Third-party services & websites

Websites you visit, sidebar apps, addons, third-party themes, streaming services, search engines, and any other third-party content or services are operated by third parties under their own terms and privacy policies. That1Dev does not control and is not responsible for their behavior, content, accuracy, availability, or data practices. A link, a default setting, or the availability of a service inside the browser is not an endorsement.

16Updates

The browser automatically checks https://pace.that1dev.com/updates/ and downloads and installs signed updates when a new version is published. Updates may add, change, or remove features, and may be necessary for security or compatibility. Updates are subject to these Terms unless they come with separate terms. If you do not want automatic updates, your only option is to stop using and uninstall the Software; running outdated versions is at your own risk.

17Feedback & submissions

If you send us feedback, feature requests, bug reports, or other ideas (through the website form, email, or the issue tracker), you grant us a perpetual, irrevocable, worldwide, royalty-free license to use them for any purpose — including building them into the Software — without compensation, attribution, or any obligation to you. Don't send us anything confidential; we can't accept obligations of confidentiality over unsolicited submissions.

18Donations

Donations (for example, through GitHub Sponsors) are voluntary and non-refundable, are processed by the third-party platform under its own terms, and do not purchase any product, service, feature, support commitment, or influence over the Software's direction. Donating does not change your license or create any additional obligations on our part.

19The website

These Terms also govern your use of the Pace Browser website and first-party services at https://pace.that1dev.com. You agree not to interfere with their operation, misuse the feedback form or Addon Shop (including spam or automated submissions), probe or overload the update and PaceSync services, or attempt to gain unauthorized access to any related account, storage, or system. Information submitted through the website and Shop is handled as described in the Privacy Policy.

20Disclaimer of warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. THAT1DEV EXPRESSLY DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT LIMITATION ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, QUIET ENJOYMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THE FOREGOING, THAT1DEV DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE; THAT DEFECTS WILL BE CORRECTED; THAT ANY WEBSITE, ADDON, OR STREAMING SERVICE WILL FUNCTION WITH THE BROWSER; OR THAT THE AD BLOCKER WILL BLOCK ALL ADS OR TRACKERS. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU; IN THAT CASE, ANY MANDATORY WARRANTIES ARE LIMITED TO THE MINIMUM SCOPE AND DURATION REQUIRED BY LAW.

21Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL THAT1DEV BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, CREDENTIALS, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO THE SOFTWARE OR THESE TERMS — WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THAT1DEV'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SOFTWARE OR THESE TERMS WILL NOT EXCEED FIFTY U.S. DOLLARS (US $50) OR THE AMOUNT YOU PAID US FOR THE SOFTWARE IN THE TWELVE MONTHS BEFORE THE CLAIM, WHICHEVER IS GREATER. (THE SOFTWARE IS FREE, SO THAT AMOUNT WILL TYPICALLY BE US $50.)

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including, where applicable, liability for fraud or for death or personal injury caused by negligence. If you are a consumer in a jurisdiction with mandatory consumer-protection laws, you retain all rights those laws grant you.

22Indemnification

To the extent permitted by law, you agree to indemnify and hold harmless That1Dev from and against claims, damages, liabilities, and reasonable expenses (including legal fees) arising out of your violation of these Terms, your misuse of the Software, any addon you develop or distribute, or your violation of any law or third-party right while using the Software.

23Termination

These Terms apply for as long as you use the Software. You may terminate them at any time by uninstalling the browser and ceasing all use. Your license terminates automatically if you materially breach these Terms. We may also discontinue the Software, the Addon Shop, the website, or any feature at any time, with or without notice.

Upon termination, Sections 5, 6, 17, 20, 21, 22, and 25 survive. Uninstalling the browser removes your local browsing data as described in the Privacy Policy.

24Changes to these Terms

We may update these Terms from time to time — for example, to reflect new features or legal requirements. When we do, we will update the "Last updated" date at the top of this page, and for material changes we will make reasonable efforts to provide more prominent notice (such as a note on the website or in the browser). Your continued use of the Software after changes take effect constitutes acceptance of the updated Terms. If you do not agree to a change, stop using and uninstall the Software.

25General provisions

  • Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and That1Dev regarding the Software and supersede any prior agreements on that subject.
  • Severability. If any provision of these Terms is held unenforceable, it will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions remain in full effect.
  • No waiver. Our failure to enforce any provision is not a waiver of our right to enforce it later.
  • Assignment. You may not assign these Terms. We may assign them in connection with a reorganization, sale, or transfer of the Software.
  • Governing law. These Terms are governed by the laws applicable in That1Dev's place of residence, without regard to conflict-of-law rules, except where the mandatory consumer-protection law of your country of residence applies instead. Before pursuing any formal dispute, please contact us — most issues can be resolved quickly by email.
  • Export compliance. You agree to comply with applicable export-control and sanctions laws in connection with your use of the Software.
