Terms of Service

Last updated July 8, 2026

1. Agreement to terms

These Terms of Service (“Terms”) form a binding agreement between you and Line Ledger, Inc. (“LineLedger,” “we,” “us”) governing your access to and use of the LineLedger website at lineledger.org (the “Site”). By using the Site, you agree to these Terms together with our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the Site.

These Terms do not govern the LineLedger software. The software is free and open source, licensed to you under the GNU Affero General Public License v3 (“AGPLv3”). Your rights to run, study, modify, and redistribute it come from that licence — not from this document. See section 3.

2. What LineLedger is

LineLedger is double-entry accounting software published under the AGPLv3. You obtain it from our public repository and run it on infrastructure you control.

We operate no hosted service. There is no LineLedger account, no subscription, no trial, and no paid tier. We do not host your books, we never receive your accounting data, and we have no ability to access, suspend, or delete it. What you install is yours to run for as long as you like.

This Site is marketing and documentation. Its only interactive features are a contact form and a public feature-request board.

3. The software licence

The LineLedger application is released under the AGPLv3 — see the LICENSE for the full terms and your rights.

The AGPLv3 and these Terms are separate. The AGPLv3 governs your rights in the software. These Terms govern your use of this website. Nothing here narrows the rights the AGPLv3 grants you, and nothing in the AGPLv3 grants you rights in our trademarks or in this Site’s content.

In brief, and without modifying the licence itself: you may run LineLedger for any purpose, read and modify its source, and redistribute it. If you modify LineLedger and make that modified version available to others over a network, the AGPLv3 requires you to offer those users the source of your modifications. Keeping your own books is not distribution and triggers no such obligation.

4. Trademarks

“Line Ledger,” “LineLedger,” the LineLedger logo, the LineLedger wordmark, and related names, slogans, and visual identifiers are trademarks of Line Ledger, Inc. (the “LineLedger Marks”).

The AGPLv3 grants rights in the source code only. It grants no right, express or implied, in the LineLedger Marks. Without our prior written permission, you may not:

  • use the LineLedger Marks, or any confusingly similar mark, in the name, branding, domain name, social-media handle, package name, or marketing of any product, service, fork, derivative work, or distribution;
  • represent or imply that any fork, derivative work, hosted instance, or third-party service is endorsed, sponsored, certified, affiliated with, or produced by Line Ledger, Inc.; or
  • reproduce, modify, or display the LineLedger logo other than as required for unmodified redistribution of the repository as permitted by the AGPLv3.

If you fork or redistribute LineLedger, you must remove or replace the LineLedger Marks with your own branding. Nominative references (“compatible with LineLedger,” “imported from LineLedger”) are permitted where truthful, non-misleading, and not suggestive of endorsement.

Third-party names, logos, and marks referenced on this Site are the property of their respective owners and are used for identification purposes only.

5. Acceptable use of this site

You agree not to:

  • Use the Site to violate any law or the rights of any third party.
  • Disrupt, overload, or impair the Site or the servers or networks that deliver it.
  • Attempt to gain unauthorized access to any system or data.
  • Probe or scan our infrastructure. (You are of course free to study, modify, and redistribute the AGPLv3 software itself under that licence, on your own machines.)
  • Submit unsolicited communications, spam, or malicious code through the contact form or the feature-request board.

6. Submissions and feedback

If you send us a message, a bug report, a feature request, or any other suggestion, you grant us a non-exclusive, royalty-free, perpetual licence to use it to improve LineLedger, without obligation to you. Do not send us anything you consider confidential.

The feature-request board is public. Anything you post there — including the name you attach to it — is visible to everyone. We may edit or remove submissions at our discretion.

7. Not professional advice

LineLedger is software that helps you keep records and prepare information. It is not a substitute for professional accounting, bookkeeping, tax, payroll, audit, or legal advice, and using it does not create an accountant-client or other professional relationship. LineLedger is not your accountant, bookkeeper, tax preparer, or auditor.

You are solely responsible for:

  • The accuracy, completeness, and legality of the data you enter and of the records, reports, financial statements, returns, and forms you generate.
  • Determining and meeting your own tax, payroll, regulatory, reporting, and filing obligations — including, where applicable, sales tax / GST / HST / PST, source deductions and year-end payroll filings, T-slips, and US Form 1099 / W-9 collection and filing. The software may help you prepare calculations and forms, but it does not file on your behalf and does not guarantee that any calculation, form, or filing is correct, complete, or accepted by any tax or government authority.
  • Operating, securing, and backing up the server you run LineLedger on, and maintaining current exported copies of your data.

We do not warrant that tax rates, calculations, or rules built into the software are error-free or current. You should review its outputs and consult a qualified accountant, tax advisor, or lawyer before relying on them or making a filing.

AI features. Some optional features (for example, the Business Q&A integration) let you ask questions about your data through an AI assistant, which you configure with your own provider credentials. AI-generated answers are informational only, may be incomplete or inaccurate, and must be independently verified by a qualified person before you rely on them for any financial, tax, or filing decision.

8. Disclaimer of warranties

The Site and the software are provided on an “as is” and “as available” basis. To the maximum extent permitted by applicable law, we disclaim all warranties of any kind, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, completeness, and uninterrupted or error-free operation. The AGPLv3 contains its own warranty disclaimer for the software, which applies on its own terms. Some jurisdictions, including parts of Canada, do not allow the exclusion of certain warranties — in those cases the exclusions above apply to the fullest extent permitted, and you may have additional statutory rights that these Terms do not override.

We may modify the Site, change or discontinue the software, or stop publishing it, at any time and without notice. We do not guarantee any specific uptime for the Site. Because you hold your own copy of the source and your own data, none of this can take your books away from you.

9. Limitation of liability

To the maximum extent permitted by applicable law, LineLedger and its contributors, officers, employees, and agents will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or business opportunity, arising out of or relating to the Site or the software, even if we have been advised of the possibility of such damages.

Your data. You install and operate LineLedger yourself. We do not host, store, back up, or have access to your accounting data, and we bear no responsibility for its loss, corruption, or unavailability. Maintaining backups is entirely your responsibility.

To the maximum extent permitted by applicable law, our total aggregate liability to you for any and all claims relating to the Site or the software will not exceed CAD $100. You have paid us nothing, and we have received nothing from you.

Nothing in these Terms limits liability that cannot be limited under applicable law, including for gross negligence, willful misconduct, or fraud.

10. Indemnification

You agree to defend, indemnify, and hold harmless LineLedger and its contributors from and against any claims, damages, losses, and reasonable costs (including reasonable lawyers’ fees) arising out of or related to: (a) your breach of these Terms; (b) your use of the Site or the software; (c) content you submit to us; (d) your operation or distribution of a modified version of LineLedger; or (e) your violation of any law or third-party right.

11. Governing law, arbitration, and dispute resolution

Governing law. These Terms are governed by the laws of the Province of British Columbia and the federal laws of Canada applicable therein, without regard to conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Informal resolution first. Before starting a formal proceeding, you agree to contact us at [email protected] and give us at least 30 days to resolve the dispute informally. Most concerns can be resolved this way.

Binding arbitration. Except for the carve-outs below, any dispute, claim, or controversy arising out of or relating to these Terms or the Site that is not resolved informally will be resolved by final and binding arbitration on an individual basis, rather than in court. The arbitration will be administered by the ADR Institute of Canada under its Arbitration Rules, seated in Vancouver, British Columbia, conducted in English before a single arbitrator. Judgment on the award may be entered in any court of competent jurisdiction. The arbitrator has authority to decide the interpretation and scope of this arbitration agreement, except for the class-action waiver below, which only a court may decide.

Class-action waiver. To the maximum extent permitted by applicable law, you and LineLedger each agree that disputes will be brought only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. If this class-action waiver is found unenforceable as to a particular claim or remedy, then that claim or remedy (and only that one) will be severed and may proceed in court, while all remaining claims continue in arbitration.

Carve-outs. Either party may (a) bring an individual claim in small-claims court if it qualifies, and (b) seek injunctive or equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information.

Court venue. For any dispute that is not subject to arbitration, you and LineLedger submit to the exclusive jurisdiction of the courts located in Vancouver, British Columbia.

Non-waivable consumer rights. Nothing in this section removes any non-waivable right that applicable consumer-protection law in your jurisdiction guarantees you — including, where such law so provides, the right to bring proceedings in your local courts or to participate in collective proceedings. Where a mandatory consumer-protection law conflicts with the arbitration or class-action terms above, that law prevails to the extent of the conflict.

Disputes about the software licence are governed by the AGPLv3 itself, not by this section.

12. Changes to these terms

We may update these Terms from time to time. When we do, we will post the revised Terms here and update the “Last updated” date above. Your continued use of the Site after the changes take effect constitutes acceptance of the revised Terms. If you do not agree, stop using the Site. Changes to these Terms have no effect on the AGPLv3 licence already granted to any copy of the software you hold.

13. Miscellaneous

These Terms, together with our Privacy Policy, are the entire agreement between you and LineLedger regarding the Site, and supersede any prior agreements on the same subject. If any provision is held unenforceable, the remaining provisions remain in effect. Our failure to enforce a provision is not a waiver of our right to do so later. You may not assign these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, or sale of substantially all of our assets. Headings are for convenience only and do not affect interpretation.

Sections that by their nature should survive — including Trademarks, Submissions and Feedback, Not Professional Advice, Disclaimer of Warranties, Limitation of Liability, Indemnification, Governing Law, and this section — will survive any termination of your use of the Site.
