Terms of Service

1. Acceptance and capacity

You may use the Platform only if you have the legal capacity to enter into a binding contract under the Indian Contract Act, 1872 or the law of the jurisdiction in which you are resident. You confirm that you are at least eighteen (18) years of age. If you are using the Platform on behalf of an organisation, you confirm that you have authority to bind that organisation, and references to "you" include that organisation.

These Terms are an electronic record under the Information Technology Act, 2000. They do not require a physical or digital signature to be binding.

2. Description of the Platform

The Platform processes flight log files recorded by ArduPilot and PX4 flight controllers to produce 3D flight visualisations, parameter graphs, automated diagnostic summaries, and PDF flight reports. The Vector AI feature is a retrieval-augmented assistant that answers questions grounded in the telemetry of the specific log you are viewing and in publicly available drone engineering reference material.

The Platform is intended for post-flight analysis. It is not a flight control system, a flight planning system in the sense of the DGCA Digital Sky platform, an air traffic services system, or a real-time operational decision support system. We say more about this in Section 8 (Disclaimers).

The Platform is provided on an "as is" and "as available" basis. We make no commitment that it will be uninterrupted, error-free, or available at a particular service level except where an Enterprise Order Form between you and us records a specific service level.

3. Account creation and security

3.1 You must provide accurate registration details and keep them current. Your account is personal to you (or your organisation, where applicable) and may not be shared with any other person who is not an authorised user under your account.

3.2 You are responsible for keeping your sign-in credentials confidential and for all activity that occurs under your account. You will notify us at hello@loghat.app as soon as you become aware of any unauthorised access.

3.3 We may suspend or terminate your account, on reasonable notice where practicable, if:

• (a) you have materially breached these Terms and not cured the breach within fifteen (15) days after we identified it in writing;
• (b) we are required to do so by law or a court order;
• (c) we reasonably suspect the account is being used for fraud, abuse, or activity that exposes the Platform or another user to legal or security risk;
• (d) your payment for a paid feature is overdue by more than thirty (30) days.

On termination of your account, the data-deletion process described in the Privacy Policy Section 6 applies.

4. Credits, payment, and billing

4.1 Credit packs. Access to log processing and to Vector AI is metered in Flight Credits. We sell Flight Credits in packs at the prices listed at loghat.app/pricing. All prices are stated in Indian Rupees and are exclusive of Goods and Services Tax (GST), which is added at the applicable rate and shown on the invoice issued through Razorpay.

4.2 What a credit buys. One Flight Credit entitles you to one log processing run (3D render, parameter graphs, forensic PDF). Each Vector AI query consumes 0.1 Flight Credits. The credit cost of features may change with prospective effect on at least 30 days' notice posted at loghat.app/pricing.

4.3 No expiry. Flight Credits purchased through the Platform do not expire. If we ever change this in the future, the change will only apply to credits purchased after the published change date, and credits purchased before the change date will continue to be governed by the policy in force at the time of purchase.

4.4 GST and place of supply. Invoices issued through the Platform carry the HSN/SAC code, place of supply, GST treatment (CGST + SGST intra-state or IGST inter-state), seller GSTIN, and buyer GSTIN where provided. If you are an Indian business customer requiring a GSTIN on the invoice, enter it on your profile before purchase. Once an invoice is issued, we will not amend it except to correct a clerical error.

4.5 Refunds. Refunds are governed by the LogHat Refund Policy and form part of these Terms by reference. The Refund Policy explains the eligibility window, partial refunds, non-refundable items, and the route to escalate a refund dispute.

4.6 Payment processor. Payments are processed by Razorpay Software Private Limited, a Payment Aggregator licensed by the Reserve Bank of India. Card details and bank credentials are submitted directly to Razorpay; we never see or store them.

5. Founding Pilot programme (closed cohort)

The Founding Pilot programme described in our 6 February 2026 Terms granted six months of complimentary "Pro" access to early registrants. That cohort continues to receive the benefit it was promised: the benefits associated with the Founding Pilot tier remain available to the original cohort for the original duration, and any unused Flight Credits associated with the cohort do not expire.

The Founding Pilot programme is closed to new signups from the effective date of these Terms. New users sign up on the Freemium tier and may purchase Flight Credits on the terms in Section 4.

6. Your content — flight logs, chat, and shared links

6.1 Ownership. You retain all right, title and interest in the flight logs, telemetry, parameter sets and any other content you upload to the Platform ("User Content"). Nothing in these Terms transfers any intellectual property in User Content to us.

6.2 Licence to operate the Platform. You grant us a worldwide, non-exclusive, royalty-free licence to host, copy, transmit, parse, analyse and display User Content solely for the purpose of providing the Platform to you and the recipients of any share link you create. The licence ends when the User Content is deleted in accordance with the Privacy Policy.

6.3 No model training. We do not use User Content to train, fine-tune, or otherwise improve any AI model — ours or a third party's. This commitment also appears in the Privacy Policy Section 3.1 and is binding on us.

6.4 Shared links. The Platform allows you to generate a share link for a flight log. Anyone with that link can view the log. You are responsible for choosing whom to share it with. We will deactivate a share link on your request from the dashboard.

6.5 User-provided regulatory or third-party content. If a flight log contains operational data about a flight conducted on behalf of a third party, you confirm that you have the necessary right or authorisation to upload that log to the Platform.

7. Acceptable use

You will not, and will not authorise anyone else to:

• (a) use the Platform for any purpose that is unlawful in the jurisdiction in which you operate the relevant flight, including operation in violation of the Drone Rules, 2021, the airspace classification under the National Airspace Map, the conditions of any Letter of Approval issued by the DGCA, or the conditions of any registration under the Digital Sky platform;
• (b) upload logs containing classified material, military operational data, or material that you are otherwise prohibited from transmitting outside a restricted facility;
• (c) reverse engineer, decompile, disassemble, or attempt to derive the source code of the Platform, except to the extent expressly permitted by applicable law that may not be excluded by contract;
• (d) circumvent the credit metering, rate limits, anti-abuse controls or paywall of any Platform feature, including by automated means or by creating multiple accounts to extend free quotas;
• (e) use the Platform to send spam, distribute malware, or conduct network reconnaissance against the Platform or its infrastructure;
• (f) use the Platform to develop a competing flight log analysis product, except for legitimate interoperability work conducted by a separate engineering team that does not have access to the Platform's interface designs.

8. Disclaimers

8.1 Post-flight diagnostic tool only. The Platform is a post-flight analysis tool. It does not provide real-time flight safety information, real-time airspace status, real-time weather, or any input that should be relied on while a flight is in progress. Do not use the Platform during the conduct of a flight.

8.2 Vector AI is an informational engineering assistant. Vector AI produces explanations grounded in the flight telemetry under analysis and in publicly available drone engineering reference material. Vector AI:

• is not a licensed aviation legal advisor;
• does not issue regulatory approvals or interpret a regulator's application of a rule to your specific facts;
• carries an internal knowledge cutoff and may not reflect the current text of any regulation or fee table;
• must not be relied on as the sole basis for any regulatory filing, Letter of Approval application, BVLOS authorisation, or commercial operation decision.

Where Vector AI cites a specific rule, fee or process, verify the current text via the relevant authority (for example, the DGCA Digital Sky portal in India, the FAA UAS portal in the United States, or the EASA U-space references in the European Union) before relying on it. The Vector AI feature includes closing knowledge-cutoff caveats on regulatory answers; they are not a formality.

8.3 Hardware, aircraft and personal safety. We are not liable for any hardware damage, loss of aircraft, personal injury, property damage or third-party claim arising from the operation of a drone even where the operation followed analysis produced by the Platform or guidance produced by Vector AI. Drone operation is an inherently risky activity. The pilot in command is solely responsible for the safe conduct of the flight.

8.4 No warranty. Except for warranties that cannot be excluded under applicable law, we disclaim all warranties, express or implied, including the implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

9. Limitation of liability

9.1 To the maximum extent permitted by law, our aggregate liability to you, however arising and whether in contract, tort (including negligence) or otherwise, will not exceed the greater of:

• (a) the amounts you have paid us for use of the Platform in the twelve (12) months immediately preceding the event giving rise to the claim; and
• (b) Indian Rupees Ten Thousand (INR 10,000).

9.2 In no event will we be liable for any indirect, incidental, special, consequential or exemplary damages, including loss of profits, loss of business opportunity, loss of data, or punitive damages, even if we have been advised of the possibility of such damages.

9.3 Nothing in these Terms limits or excludes any liability that cannot be limited or excluded under applicable law, including (where applicable) liability for death or personal injury caused by our negligence and liability that cannot be limited under the Consumer Protection Act, 2019 to a consumer for goods or services.

10. Indemnity

You will defend, indemnify and hold harmless the Company, its directors, officers, employees and authorised agents from and against any third-party claim, demand, action, loss or expense (including reasonable legal fees) arising from:

• (a) your violation of Section 7 (Acceptable use);
• (b) your infringement of a third party's intellectual property, privacy or other right by uploading any User Content;
• (c) your operation of a flight in violation of applicable aviation law, even where the Platform was used in connection with that flight;
• (d) any tax liability of yours that you have failed to discharge.

11. Intellectual property in the Platform

All intellectual property rights in the Platform, including the software, the user interface, the 3D rendering engine, the Vector AI prompt design, the diagnostic ruleset, the documentation and the trademarks "LogHat" and "Vector AI", are owned by or licensed to the Company. You receive a limited, revocable, non-exclusive, non-transferable licence to use the Platform during the term of your subscription, solely for the purpose contemplated by these Terms.

LogHat is not affiliated with the ArduPilot or PX4 open source projects. We use those flight controller stacks' file formats and documented telemetry conventions; the projects' trademarks remain those of their respective owners.

12. Modifications to the Terms

We may amend these Terms from time to time. We will notify you of a material change by email and by an in-product notice at least 14 days before the change takes effect. A change that is purely typographical or that clarifies an existing obligation without altering its substance may take effect on the date it is published, with an updated version number.

If you do not agree with an amendment, you may close your account before the amendment takes effect. Continued use of the Platform after the effective date constitutes acceptance.

13. Suspension and termination by you

You may close your account at any time from the dashboard. On closure, the data-deletion process in the Privacy Policy Section 6 applies.

Closing your account does not entitle you to a refund of unused Flight Credits except as provided in the Refund Policy. If the Refund Policy does not entitle you to a refund of unused credits, the credits are forfeited on closure.

14. Governing law and dispute resolution

14.1 These Terms are governed by the laws of India.

14.2 The courts at Noida, Gautam Buddha Nagar, Uttar Pradesh have exclusive jurisdiction over any dispute arising out of or in connection with these Terms, subject to the consumer-protection carve-out in Section 14.3, where applicable, and the arbitration agreement in Section 14.4, where applicable.

14.3 Consumer carve-out. If you are a "consumer" within the meaning of the Consumer Protection Act, 2019 and the cause of action falls within the jurisdiction of a District Consumer Disputes Redressal Commission, the State Consumer Disputes Redressal Commission or the National Consumer Disputes Redressal Commission, nothing in this Section limits your right to bring proceedings in the forum prescribed by that Act.

14.4 Arbitration (B2B only). For disputes between us and an organisation that uses the Platform in the course of a trade, business or profession, the parties will attempt to resolve the dispute in good faith for thirty (30) days. If unresolved, the dispute will be referred to and finally resolved by arbitration under the Arbitration and Conciliation Act, 1996. The seat of arbitration will be Noida. The arbitration will be conducted in English by a sole arbitrator appointed by mutual agreement; failing agreement, the appointment will be made under the rules of the Mumbai Centre for International Arbitration. The award will be final and binding.

15. Notices

Notices to us under these Terms must be sent to:

Notices to you will be sent to the email address on your account.

16. Miscellaneous

16.1 Entire agreement. These Terms, together with the Privacy Policy, the Refund Policy, the Cookie Policy, and any Order Form between us and you, contain the entire agreement between the parties in respect of the subject matter and supersede all prior agreements.

16.2 Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions will continue in full force.

16.3 Waiver. No failure or delay by either party in exercising a right under these Terms is a waiver of that right.

16.4 Assignment. You may not assign these Terms without our written consent. We may assign these Terms to a successor entity in the event of a corporate reorganisation, merger or sale of the business, on at least thirty (30) days' prior notice to you by email.

16.5 Force majeure. Neither party is liable for any delay or failure to perform caused by an event beyond its reasonable control, including natural disaster, war, civil unrest, internet or power outage, governmental order or pandemic.

16.6 No agency. Nothing in these Terms creates a partnership, joint venture, employment or agency relationship between the parties.
