These Terms of Service ("Terms") form a binding legal agreement between you ("you", "your", "User", or "Owner") and Vantage Log ("we", "us", "our", or "Vantage Log") governing your use of the Vantage Log mobile application, related web services, and any associated software (collectively, the "Service").
By creating an account, signing in, or using any part of the Service, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy. If you do not agree to these Terms, do not use the Service.
We may update these Terms from time to time. Section 17 explains how we notify you and what happens when the Terms change.
To use the Service, you must:
The Service is intended for owners, operators, and authorized mechanics of general aviation aircraft registered in the United States with the FAA. Use of the Service for other purposes is at your own risk and may not be supported.
Vantage Log is a digital companion application that helps general aviation aircraft owners digitize, organize, search, and share copies of paper maintenance logbook entries and other aircraft records. Features include:
The Service is provided as a convenience tool. It is not a substitute for paper records, an airworthiness determination tool, or a source of regulatory advice. See Section 6 for the full safety disclaimer.
5.1. Account creation. You must create an account using a valid email address and a password meeting our minimum strength requirements. You may also sign in using third-party authentication providers (Google, Apple) where supported.
5.2. Accurate information. You agree to provide accurate, current, and complete information during registration and to keep your profile updated.
5.3. Account security. You are responsible for safeguarding your password and any device on which you are signed in. You are responsible for all activity that occurs under your account, whether or not authorized by you. Notify us promptly at brian.berg@ascend-solutions.info if you suspect unauthorized access.
5.4. One account per individual. Each account is intended for use by a single individual. Sharing account credentials with others is prohibited.
5.5. Account termination by you. You may delete your account at any time from within the app. See the Delete Account page for details.
This section is critical. Read it carefully.
The Service is a digital companion application for organizing and viewing copies of aircraft maintenance records. It is not, and is not intended to be, a substitute for the paper maintenance records required by the FAA under 14 CFR §91.417, §43.9, §43.11, or any other applicable regulation. Your continued use of the Service constitutes your acknowledgment and acceptance of each of the following clauses.
The original paper logbooks and other paper records of your aircraft remain the official, authoritative, and only legally-required record of maintenance under FAA regulations. The digital entries within the Service are convenience copies. In the event of any conflict, ambiguity, or inconsistency between digital data within the Service and the original paper records, the paper records control. You must preserve the original paper records and may not rely on the Service as a substitute.
The Service does not determine, certify, or warrant that any aircraft is airworthy, current on any inspection, in compliance with any Airworthiness Directive (AD), Service Bulletin (SB), Service Letter, or other regulatory requirement, or otherwise legal to operate. The decision to operate any aircraft remains solely with the pilot in command and, where applicable, the certificated mechanic responsible for the aircraft's maintenance. You must independently verify airworthiness through your A&P, IA, or other qualified aviation professional before each flight.
The Service uses optical character recognition powered by third-party artificial intelligence models to extract structured information from photographs of physical logbook pages. OCR results may be inaccurate, incomplete, or misleading. Common failure modes include misread cursive, misread numbers (tach, hobbs, dates, certificate numbers), missed entries on multi-entry pages, incorrect inspection classification, and misidentification of signers or reference numbers. You are responsible for verifying every extracted entry against the original paper page before relying on it. Vantage Log makes no warranty as to the accuracy of OCR results.
The Service may display recommended-interval information (e.g., "next annual due in 12 months") and derived compliance status (e.g., "transponder check is overdue"). These calculations are advisory only. They are based on regulatory intervals and on data you or the OCR have entered, and they may be incorrect for many reasons: the underlying entry may have been misread by OCR, the entry may have been omitted or mistyped, the regulatory interval may not apply to your specific aircraft or operation, or the calculation logic may itself be incomplete. You must independently verify all next-due dates and compliance status with your A&P, IA, or other qualified aviation professional before relying on them. Vantage Log makes no warranty as to the accuracy of any derived compliance information and disclaims any responsibility for actions taken or not taken in reliance on it.
Nothing in the Service constitutes regulatory advice, legal advice, or guidance from the FAA or any other regulatory authority. The Service does not provide guidance on whether a given maintenance action complies with applicable regulations, whether a given mechanic is qualified to perform a given task, or whether a given aircraft is legal to operate. For regulatory questions, consult an aviation attorney, your local FAA Flight Standards District Office, or other qualified authority.
Owners may use the Service to generate exports, summaries, or shareable views of their aircraft's maintenance records for the purpose of pre-purchase inspection, sale, insurance underwriting, or other due diligence. Such exports remain convenience copies subject to the same accuracy disclaimers as the in-app data. Prospective buyers, brokers, insurers, mechanics, and other recipients must verify all records against the original paper logbooks before relying on them. Vantage Log disclaims any liability arising from a recipient's reliance on a Service-generated export.
If and when the Service offers a flow for transferring digital records from one owner to a successor owner upon sale of an aircraft, that flow governs the transfer of digital records within the Service only. It does not constitute, evidence, or facilitate the transfer of legal title to the aircraft, the paper logbooks, or any other rights. Legal title transfer must be effected separately.
While we use commercially reasonable efforts to preserve and back up your Aircraft Data, no digital service can guarantee perpetual availability or integrity. You bear the responsibility of maintaining the original paper records and, where appropriate, exporting and storing your own copies of the digital data. Loss of digital data within the Service shall not in any way impair the validity or completeness of your paper records.
To the maximum extent permitted by applicable law, Vantage Log, its officers, directors, employees, contractors, agents, suppliers, and licensors shall have no liability whatsoever for any aviation incident, accident, injury, death, regulatory action, enforcement action, loss of certificate, loss of property, financial loss, or other damages arising from your use of, or inability to use, the Service. You agree that the Service is a convenience tool only and that all decisions regarding aircraft operation, maintenance, and airworthiness remain solely your responsibility and that of the qualified aviation professionals you engage.
7.1. Subscription plans. Use of certain features of the Service requires a paid Subscription. Current plan options and pricing are displayed within the app.

The Service relies on third-party providers, including Supabase, Anthropic, Apple Inc., Google LLC, Expo, and email delivery providers. Each third-party provider operates under its own terms of service and privacy policy.
