NextProb Terms of Service
Last Updated: April 29, 2026
1. Acceptance of Terms
These Terms of Service (“Terms”) govern your access to and use of NextProb (the “Software”), provided by Helicase Space LLC (“we,” “us,” or “our”). By downloading, installing, or using NextProb, you agree to be bound by these Terms and the NextProb Privacy Policy. If you do not agree, do not install or use NextProb.
2. Description of the Software
NextProb is a local-first desktop application for creating and managing notes. Each note is a folder on your own computer containing its content, optional local storage, and optional attached scripts that you explicitly approve before they run. NextProb also embeds a terminal in which you may run AI command-line tools, and it can connect to remote AI services that you configure.
The Software is designed so that your notes and workspace remain on your own device. NextProb also offers optional features that transmit your User Content directly to a remote destination you configure and control. For example, a Git repository you own or an SSH/SFTP server. In those modes, traffic flows between your device and that destination; we do not receive, host, or store your User Content, and that destination’s terms and privacy practices govern the transfer. These features are off by default and require explicit action by you to enable.
We reserve the right to modify or discontinue the Software at any time, with or without notice. Because NextProb is distributed as a standalone application, copies you have already installed will continue to function locally even if we stop development.
3. Eligibility
You must be at least 18 years old to use the Software. By using the Software, you represent and warrant that you meet this age requirement and have the legal capacity to enter into these Terms.
4. User Content and Intellectual Property
You retain all ownership rights to the notes, files, data, scripts, and other content you create or store through the Software (“User Content”). When you use NextProb, your User Content stays on your device and we receive no rights to it.
When you sync to a destination you control, your User Content goes only to that destination. Because we do not receive, host, or process that content, you grant us no license to it.
AI providers. When you use AI features, you do so either by running an AI command-line tool inside the Software’s terminal or by configuring a remote AI provider in the Software. In both cases, your User Content travels directly from your device to the AI provider you chose. It does not pass through, and is not stored on, our servers. That transmission is governed by the terms and privacy policies of the tool or provider you selected. NextProb does not operate any AI service.
You represent and warrant that (a) you own or have the necessary rights to your User Content; (b) your User Content does not infringe third-party rights; and (c) your use of the Software complies with these Terms and all applicable laws.
The Software’s source code is licensed separately under the terms described in Section 8. The “NextProb” name, the “Helicase.space” brand and its typographic variants, and the application icon files are reserved marks and assets of Helicase Space LLC and are not licensed under the open-source license or these Terms.
5. Acceptable Use
You agree not to:
- Use the Software for any unlawful purpose or in violation of any applicable laws;
- Violate or infringe the rights of others, including intellectual property, privacy, or publicity rights;
- Use the Software to transmit viruses, malware, or malicious code to any destination;
- Impersonate any person or entity or misrepresent your affiliation;
- Use the Software to transmit spam or unsolicited communications.
Because the Software runs locally and we do not operate any service through which you publish or transmit User Content, enforcement of this Section is largely your own responsibility under applicable law and the terms of any destination you sync to.
6. Scripts and Third-Party Code
The Software can execute user-approved scripts attached to a note and can render HTML that executes JavaScript. Scripts are disabled by default and must be explicitly approved per note before they run.
You are solely responsible for the scripts, HTML, and other code that you write, import, or allow to run inside NextProb. We do not review, endorse, or guarantee the safety of any such code. Approving a script grants it the ability to read and write files inside its note’s folder, spawn subprocesses, make network requests, and access any capability exposed by your operating system to a subprocess run under your user account. Treat untrusted scripts and HTML the way you would treat any other untrusted program you might run on your machine.
7. Privacy
Your privacy is important to us. The NextProb Privacy Policy explains what limited information we collect, when, and why. By using the Software, you consent to our information practices as described there.
8. Open Source License
The NextProb Software is distributed under the GNU Affero General Public License, version 3.0 only (AGPL-3.0-only). A copy of the license is included with the Software and is available in the Software’s source repository. To the extent these Terms conflict with the AGPL-3.0 with respect to your rights to the source code, the AGPL-3.0 governs those rights.
The AGPL-3.0 covers the Software’s source code only. The “NextProb” and “Helicase.space” marks and the reserved brand assets are governed by these Terms, not the AGPL.
Additional content that the Software downloads from a public repository is licensed separately under the MIT License, a copy of which accompanies that repository.
9. Third-Party Services
The Software may interoperate with third-party tools and services that you install or configure, including AI command-line tools and the third-party AI providers they contact, remote destinations you choose to sync to, and any third-party content you load into the app. We do not control these third parties, and your use of them is governed by their terms and privacy policies, not ours.
10. Termination
You may stop using the Software at any time by uninstalling it. We may discontinue the Software at any time. Discontinuation does not disable your local copy of the Software; it will continue to function on your device until you uninstall it.
Sections that by their nature should survive termination (including ownership provisions, warranty disclaimers, limitations of liability, indemnification, and dispute resolution) survive.
11. Disclaimers and Warranties
THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
WE DO NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT THE SOFTWARE IS FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS.
YOU ACKNOWLEDGE THAT OUTPUT PRODUCED BY AI TOOLS INVOKED FROM THE SOFTWARE MAY CONTAIN ERRORS OR INACCURACIES. WE DO NOT WARRANT THE ACCURACY, COMPLETENESS, OR USEFULNESS OF ANY AI-GENERATED CONTENT, AND WE DO NOT WARRANT THE BEHAVIOR OF ANY USER-APPROVED SCRIPT OR THIRD-PARTY CODE THAT YOU RUN INSIDE THE SOFTWARE.
12. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL HELICASE SPACE LLC, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING FROM:
- Your access to or use of, or inability to access or use, the Software;
- Any conduct or content of any third party or any AI tool invoked from the Software;
- Any User Content or content obtained from the Software;
- Any script, HTML, or other code that you write, import, or allow to run inside the Software;
- Any destination you sync to or any unauthorized access to it.
IN NO EVENT SHALL OUR TOTAL LIABILITY TO YOU FOR ALL CLAIMS RELATING TO THE SOFTWARE EXCEED ONE HUNDRED U.S. DOLLARS ($100).
13. Indemnification
You agree to indemnify, defend, and hold harmless Helicase Space LLC and its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising out of or connected with (a) your use of the Software; (b) your User Content; (c) scripts or other code you write, import, or run inside the Software; (d) your violation of these Terms; or (e) your violation of any rights of another.
14. Dispute Resolution and Arbitration
Any dispute arising from these Terms or the Software shall be resolved through binding arbitration administered by the American Arbitration Association in accordance with its rules, rather than in court, except that you may assert claims in small claims court if your claims qualify.
You and Helicase Space LLC agree that any dispute-resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action.
If you do not wish to be bound by this arbitration provision, you must notify us in writing at legal@helicase.space within 30 days of first accepting these Terms.
15. Governing Law
These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict-of-law provisions.
16. Changes to These Terms
We may modify these Terms from time to time. If we make material changes, we will notify you through the Software or by updating the “Last Updated” date at the top of these Terms before the changes take effect. Your continued use of the Software after the effective date constitutes acceptance of the revised Terms. If you do not agree, stop using the Software.
17. General Provisions
Entire Agreement. These Terms, together with the NextProb Privacy Policy, constitute the entire agreement between you and Helicase Space LLC regarding NextProb and supersede any prior agreements on that subject.
Severability. If any provision of these Terms is found unenforceable, the remaining provisions will continue in full force and effect.
Waiver. No waiver of any term shall be deemed a further or continuing waiver of that term or any other term.
Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms without restriction.
