Welcome to instabooks. These Terms of Service ("Terms") form a binding agreement between You and Lightweight Labs LLC ("Company," "We," "Us," or "Our") and govern Your access to and use of the instabooks web application and related services (the "Service").
Please read these Terms carefully. They include important provisions affecting Your legal rights, including a binding arbitration agreement and class action waiver. By creating an Account or otherwise accessing or using the Service, You agree to be bound by these Terms and Our Privacy Policy. If You do not agree, do not use the Service.
You must be at least 18 years old and capable of forming a binding contract to use the Service. If You use the Service on behalf of a company or other legal entity, You represent that You have authority to bind that entity to these Terms.
The Service is intended for use by businesses, accounting professionals, and bookkeepers. It is not intended for personal, family, or household purposes.
You must provide accurate, complete, and current information when creating an Account, and You agree to keep that information up to date. You are responsible for safeguarding Your authentication credentials and for all activity that occurs under Your Account. You agree to notify Us immediately at founders@lightweightlabs.com of any unauthorized use.
If Your Account is used on behalf of an entity, that entity is responsible for the actions of authorized users. We may rely on instructions and authorizations received through the Account without independent verification.
Subject to Your compliance with this Agreement, the Company grants You a revocable, non-exclusive, non-transferable, limited right to access and use the Service for Your internal business or professional accounting purposes.
You may not (i) copy, modify, or create derivative works of the Service; (ii) reverse engineer, decompile, or otherwise attempt to discover the source code or underlying structure of the Service, except to the extent expressly permitted by applicable law; (iii) rent, lease, sell, sublicense, assign, distribute, or otherwise transfer Your access to the Service; (iv) remove or obscure any proprietary notices; (v) use the Service in any manner that violates applicable law; or (vi) use the Service to develop a product or service that competes with the Service.
You retain all rights in, and are solely responsible for, Content You make available through the Service, including data You authorize Us to access from QuickBooks Online. We do not claim ownership of Your Content.
You grant Us a non-exclusive, worldwide, royalty-free license to host, store, transfer, display, and process Your Content solely as necessary to provide, maintain, secure, and improve the Service, and as otherwise permitted by Our Privacy Policy.
The Service is designed to work with QuickBooks Online through Intuit's authorized developer platform. To use most features You must authorize the Service to access Your Intuit account using the OAuth scopes published by Intuit.
You acknowledge that:
The Service may display, include, or link to other third-party services. The Company does not control and is not responsible for Third-Party Services, including their accuracy, completeness, timeliness, legality, or quality. Your use of any Third-Party Service is at Your own risk and subject to that third party's terms.
The Service is currently offered free of charge during an early access period. The Company reserves the right to introduce paid plans, tiers, or usage-based fees in the future.
If the Company introduces fees for features You use, We will provide at least thirty (30) days' advance notice by email or in-product notice. You will have the option to (i) accept the new terms and continue using the paid features, or (ii) discontinue use of the paid features before the fees take effect. Continued use of the affected features after the effective date constitutes acceptance of the new terms.
If You purchase a paid plan, You agree to pay the applicable fees and any taxes, except for taxes based on Our net income. Fees are non-refundable except as expressly stated or as required by law. If You fail to pay, We may suspend or terminate Your access to the paid features.
Where automatic renewals or recurring billing apply to a paid plan, the specific renewal terms (renewal period, cancellation deadline, and method of cancellation) will be disclosed to You at the time of purchase as required by applicable law (including California Business & Professions Code § 17600 et seq., the New York Auto-Renewal Law, and similar laws). You may cancel a recurring subscription at any time through Your Account settings.
You agree not to use the Service to:
This Agreement remains in effect until terminated. You may terminate at any time by closing Your Account and discontinuing use of the Service.
We may suspend or terminate Your access to the Service if We reasonably believe You have violated this Agreement, or if We are required to do so by law, or to protect the security or integrity of the Service or other users. We will provide notice where reasonably practicable; immediate suspension is permitted when required for security, legal, or operational reasons.
Data after termination. Because QuickBooks Online is the system of record for Your accounting data, Your books remain available to You in Your Intuit account regardless of Your status with the Service. After termination, We will delete or de-identify mirrored Content within thirty (30) days, subject to the limited retention described in Our Privacy Policy (for example, backups and legally required records). You should ensure You have access to Your Intuit account before terminating.
Provisions that by their nature should survive termination shall survive, including license restrictions, ownership, warranty disclaimers, indemnification, limitations of liability, and dispute resolution.
By You. You agree to indemnify, defend, and hold harmless the Company and its officers, directors, employees, agents, and affiliates from and against any third-party claim, demand, loss, liability, damage, or expense (including reasonable attorneys' fees) arising out of or related to (a) Your use of the Service, (b) Your Content, (c) Your breach of this Agreement, or (d) Your violation of any law or third-party right.
By Us. Subject to the limitations in Section 13, the Company will indemnify, defend, and hold You harmless from and against any third-party claim alleging that Your authorized use of the Service, as provided by the Company, infringes a valid United States patent, copyright, or trademark of a third party. The Company's obligation does not apply to claims arising from (i) Your Content, (ii) use of the Service in combination with products or services not provided by the Company, (iii) modifications to the Service not made by the Company, or (iv) use of the Service contrary to this Agreement or Our documentation.
Process. The party seeking indemnification must (i) promptly notify the indemnifying party in writing of the claim, (ii) give the indemnifying party sole control of the defense and settlement (provided that no settlement may impose obligations on the indemnified party without its consent), and (iii) provide reasonable cooperation at the indemnifying party's expense.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING, COURSE OF PERFORMANCE, OR USAGE OF TRADE.
THE COMPANY DOES NOT WARRANT THAT THE SERVICE WILL MEET YOUR REQUIREMENTS, BE UNINTERRUPTED OR ERROR-FREE, OR THAT DEFECTS WILL BE CORRECTED. THE SERVICE IS NOT A SYSTEM OF RECORD FOR YOUR BOOKS; QUICKBOOKS ONLINE OR OTHER AUTHORITATIVE THIRD-PARTY SERVICES REMAIN THE CANONICAL RECORD OF YOUR ACCOUNTING DATA. YOU ARE SOLELY RESPONSIBLE FOR REVIEWING THE ACCURACY OF YOUR BOOKS AND MAINTAINING APPROPRIATE BACKUPS.
Some jurisdictions do not allow certain warranty exclusions, so some of the above may not apply to You. In such cases, the exclusions apply to the maximum extent permitted by law.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL THE COMPANY OR ITS SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST DATA, BUSINESS INTERRUPTION, OR LOSS OF GOODWILL, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE.
THE COMPANY'S AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE TOTAL FEES PAID BY YOU TO THE COMPANY IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).
THESE LIMITATIONS APPLY REGARDLESS OF THE LEGAL THEORY (CONTRACT, TORT, STRICT LIABILITY, OR OTHERWISE) AND WILL APPLY EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES; IN SUCH JURISDICTIONS THESE LIMITATIONS APPLY TO THE MAXIMUM EXTENT PERMITTED BY LAW.
Please read this section carefully. It affects Your legal rights.
Informal resolution. Before initiating any formal dispute, You agree to attempt to resolve the dispute informally by contacting Us at founders@lightweightlabs.com. We will attempt to resolve the dispute within sixty (60) days.
Binding arbitration. If informal resolution fails, any dispute, claim, or controversy arising out of or relating to this Agreement or the Service will be resolved by binding individual arbitration administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules (or, for individual consumer claims, the AAA Consumer Arbitration Rules) then in effect. The arbitration will be conducted in New York County, New York, or by video or telephone where permitted by the rules. The arbitrator's decision will be final and binding, and judgment may be entered in any court of competent jurisdiction. The Federal Arbitration Act governs the interpretation and enforcement of this provision.
Class action waiver. YOU AND THE COMPANY EACH AGREE THAT DISPUTES WILL BE RESOLVED ONLY ON AN INDIVIDUAL BASIS AND NOT AS A CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE ACTION. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS AND MAY NOT PRESIDE OVER ANY FORM OF REPRESENTATIVE OR CLASS PROCEEDING. If this class action waiver is found unenforceable as to a particular claim, that claim will be severed and proceed in court, but the remaining claims will continue in arbitration.
Exceptions. Either party may bring an individual action in small claims court for disputes within that court's jurisdiction. Either party may seek injunctive or equitable relief in court for actual or threatened infringement or misappropriation of intellectual property rights.
30-day opt-out. You may opt out of this arbitration agreement by sending written notice to founders@lightweightlabs.com within thirty (30) days of first accepting these Terms, stating Your name and Your election to opt out. Opting out will not affect any other provision of this Agreement.
This Agreement is governed by the laws of the State of New York, without regard to its conflict-of-law principles. To the extent a dispute is not subject to arbitration under Section 14, the parties consent to the exclusive jurisdiction and venue of the state and federal courts located in New York County, New York, and waive any objection based on inconvenient forum.
We may modify this Agreement from time to time. If a change is material, We will provide at least thirty (30) days' advance notice (by email or in-product notice) before the change takes effect. What constitutes a material change will be determined in Our reasonable discretion. By continuing to use the Service after the effective date, You agree to the revised Agreement. If You do not agree, You must stop using the Service.
If any provision of this Agreement is held unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will continue in full force and effect. Our failure to enforce a right or provision is not a waiver of that right or provision.
You represent that (i) You are not located in, under the control of, or a national or resident of any country subject to U.S. government embargo or designated as a "terrorist supporting" country, and (ii) You are not on any U.S. government list of prohibited or restricted parties.
This Agreement, together with the Privacy Policy and Subprocessors List, constitutes the entire agreement between You and the Company regarding the Service and supersedes all prior or contemporaneous agreements on the subject. You may be subject to additional terms when You use specific features or paid services, which We will present at the time of use.
