Terms of Service
1. Agreement to Terms
By downloading, installing, or using Blockr, you agree to be bound by these Terms of Service. If you do not agree, do not use Blockr.
These Terms form a legal agreement between you and twoplus11 LLC, a Missouri limited liability company ("we," "us," or "our").
2. The Application
Blockr is a macOS network monitor and per-application firewall. It installs a network content-filter system extension that observes outbound connections made by applications on your Mac, records them locally, and allows or blocks them according to rules you set — per application, or per remote host. When an application Blockr has not seen before opens a connection, that connection is held briefly while Blockr asks you what to do. Blockr does not inspect, decrypt, or proxy the contents of your network traffic. Everything runs entirely on your own Mac. It is distributed from twoplus11.com/blockr/.
3. License
Personal License (Free)
We grant you a free, non-exclusive, non-transferable, revocable license to install and use Blockr on your personal computers for non-commercial purposes. Personal use means use by an individual for personal, non-revenue-generating activities. The personal tier is the complete application — there are no locked features, trial timers, or nag screens.
Commercial License ($5 per device, one-time)
If you use Blockr in connection with any business, employment, commercial, or revenue-generating activity, you must purchase a Commercial License for each device on which Blockr is installed. A Commercial License covers one device for the lifetime of the software. You may purchase a Commercial License at twoplus11.com/blockr/#pricing.
Your license is personal and non-transferable. You may not transfer, sublicense, or assign it to another person or entity.
4. Restrictions
You agree not to:
- Distribute, sell, rent, lease, or sublicense Blockr to any third party
- Reverse engineer, decompile, or disassemble Blockr except where expressly permitted by applicable law
- Remove or alter any copyright, trademark, or other proprietary notices
- Use Blockr for any illegal purpose or in violation of any applicable laws
- Use Blockr to access or delete files you do not own or are not authorized to modify
5. Third-Party Components
Blockr is built entirely with Apple's own frameworks and bundles no third-party components. If any open-source component is ever added, it will remain the property of its respective authors and be governed by its own license, the full text of which would ship inside the application. Nothing in these Terms limits your rights under any such license.
6. Intellectual Property
Blockr, its design, original code, and all associated intellectual property rights — excluding any third-party components — are owned by twoplus11 LLC. These Terms do not transfer ownership of the application. All rights not expressly granted are reserved.
7. Updates and Availability
We may release updates to Blockr that add features, fix bugs, or change behavior. Updates are free for the lifetime of your license. We reserve the right to discontinue Blockr at any time without notice, though existing downloads will remain functional.
8. Payments and Refunds
Commercial License purchases are processed by Stripe; we never see or store your full card details. Your license key is emailed to you immediately after payment. All sales are final. If you experience a technical issue that prevents Blockr from working on your machine, contact us at jeremy@twoplus11.com and we'll work to resolve it or issue a refund at our discretion.
9. Disclaimer of Warranties
BLOCKR IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT BLOCKR WILL BE ERROR-FREE, UNINTERRUPTED, OR MEET YOUR SPECIFIC REQUIREMENTS. BLOCKR IS A NETWORK FILTER: RULES YOU SET, OR THE DEFAULT ACTION YOU CHOOSE, MAY PREVENT APPLICATIONS ON YOUR MAC FROM REACHING THE NETWORK, WHICH CAN CAUSE THOSE APPLICATIONS TO FAIL, LOSE DATA IN TRANSIT, OR BEHAVE UNEXPECTEDLY. BLOCKR IS NOT A SUBSTITUTE FOR ANTIVIRUS, INTRUSION DETECTION, OR OTHER SECURITY SOFTWARE, AND WE DO NOT WARRANT THAT IT WILL DETECT OR PREVENT ANY PARTICULAR CONNECTION, INTRUSION, OR MALICIOUS ACTIVITY. YOU ARE RESPONSIBLE FOR THE RULES YOU CONFIGURE AND FOR MAINTAINING BACKUPS OF YOUR DATA.
10. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, TWOPLUS11 LLC SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF DATA, LOSS OF PROFITS, OR LOSS OF GOODWILL. OUR TOTAL CUMULATIVE LIABILITY TO YOU FOR ANY CLAIM ARISING FROM THESE TERMS OR YOUR USE OF BLOCKR SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR YOUR LICENSE IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) FIFTY DOLLARS ($50 USD).
11. Governing Law
These Terms are governed by and construed in accordance with the laws of the State of Missouri, United States, without regard to its conflict of law principles. Any dispute arising under these Terms shall be subject to the exclusive jurisdiction of the courts located in Missouri.
12. Changes to These Terms
We may revise these Terms from time to time. We will update the "Effective date" at the top of this page. Your continued use of Blockr after any revision constitutes your acceptance of the updated Terms.
