Terms of Service

These Terms of Service ("Terms") are an agreement between you and HamburgerLabs Limited, a company registered in England and Wales under company number 17211878, with its registered office at 5 Temple Road, Croydon, England, CR0 1HU. HamburgerLabs Limited trades as Klearburn and operates klearburn.com ("Klearburn", "we", "us"). These Terms govern your access to the Klearburn website, application, APIs, and related services (the "Service"). By creating an account, starting a trial, or using the Service, you agree to these Terms and acknowledge our Privacy Policy.

You must be at least 18 and use the Service for business or professional purposes. If you use Klearburn for a company or another person, you confirm that you have authority to bind them; "you" includes that organisation. If you do not agree to these Terms, do not use the Service.

Klearburn is financial planning and record-keeping software. Depending on the features and integrations you enable, it can import invoices and receipts from Gmail, file documents in Google Drive, import bank and Stripe activity, upload and analyse contracts, reconcile transactions, track vendors and AI spend, and create budgets, hiring plans, scenarios, models, dashboards, and runway forecasts.

We may improve, add, change, or remove features. We will give reasonable notice where practicable before a change materially reduces the core functionality of a paid Service. No service-level agreement, guaranteed uptime, support response time, or data-recovery commitment applies unless we agree one with you in writing.

• Provide accurate account and billing information and keep it current.
• Keep your Google account, devices, sessions, API keys, bank tokens, and other credentials secure.
• Use least-privilege or read-only credentials where the connected provider supports them.
• Tell us promptly at legal@klearburn.com if you suspect unauthorised access or a compromised connection.
• You are responsible for activity carried out through your account unless it results from Klearburn’s breach of these Terms or failure to use reasonable security measures.

One person must not use another person’s account, and account access must not be sold or shared publicly.

You retain ownership of the documents, financial records, prompts, models, dashboard configurations, and other content you submit or connect ("Customer Data"). You grant Klearburn and the providers described in our Privacy Policy a worldwide, non-exclusive, limited licence to host, copy, transmit, transform, and process Customer Data only to provide, secure, maintain, and support the Service, comply with law, and act on your instructions.

You confirm that you have all rights, permissions, notices, and lawful bases needed for Customer Data and every Google, Drive, bank, Stripe, AI-provider, or other account you connect. This includes personal data about employees, contractors, customers, and suppliers. Do not connect an account or submit information you are not authorised to use.

Klearburn’s optional read-only Stripe connection imports data from your business’s Stripe account for reporting and reconciliation. That connected data source is separate from Stripe’s role as the underlying payment processor for Klearburn subscriptions administered through Autumn.

Integrations are optional and operate under the provider’s own terms, privacy notice, availability, and account permissions. This includes Google, GoCardless, your bank or payment provider, Stripe, Autumn, and your selected AI provider. You authorise Klearburn to exchange the information necessary to perform the feature you enable. We are not responsible for a third party’s systems, outages, pricing, account actions, or changes to its API.

You can disconnect a source or revoke its permission, but doing so may stop dependent features. Imported records may remain in Klearburn until you delete them or your account. Files Klearburn creates in your Google Drive remain in your Drive and are controlled by you.

Klearburn’s AI features use the Anthropic, OpenAI, or Google model and API key you select. You contract with and pay that provider directly. Its charges, rate limits, content rules, data retention, training settings, and service quality are your responsibility. Klearburn’s use of your key does not make us the reseller of the provider’s service.

AI outputs may be inaccurate, incomplete, non-unique, or similar to output supplied to someone else. You must review outputs and source records before using them. Your rights in an AI output, if any, are subject to applicable law and the provider’s terms; Klearburn does not guarantee that an output is protectable or does not infringe another person’s rights.

• Plan: Klearburn Pro is US $29/month plus a metered fee equal to 0.1% of Klearburn’s estimated USD cost of AI calls made through in-app AI features.
• Measurement: estimated AI cost is calculated from recorded token usage and Klearburn’s model-pricing data, not from the final invoice issued by your AI provider. The metered fee is billed in arrears in $0.01 blocks, so monthly rounding may increase the calculated fee by less than $0.01.
• Trial: a new subscription includes a 14-day free trial and requires a payment method. Klearburn’s base and metered fees accrued during the trial are waived. Your AI provider may still charge you directly for usage under your API key.
• Billing providers: Autumn administers Klearburn’s subscription, trial, and metered billing, with Stripe as the underlying payment processor. You authorise them to charge the payment method supplied at checkout.
• Renewal: after the trial, the subscription renews automatically each month until cancelled. Prices are in USD. Any VAT or other tax Klearburn is legally required to collect in the United Kingdom will be shown at checkout. Your bank or payment provider may separately charge for currency conversion.

You can manage or cancel through Settings → Billing, which opens the Autumn billing portal. Cancellation takes effect as shown in that portal, normally at the end of the paid billing period; you keep access until then unless the account is suspended or deleted. We may correct billing errors.

If payment fails or an amount remains overdue, we may retry collection, provide limited or read-only access, suspend the Service, or terminate the subscription. We may change pricing on at least 30 days’ notice; a price change applies no earlier than your next renewal after that notice.

You must not, and must not help anyone else to:

• break the law, facilitate fraud, launder money, evade sanctions, or violate another person’s rights;
• access, upload, or process an account, system, or data without proper authority;
• submit malware, malicious code, or content designed to compromise a model, provider, or user;
• probe, scan, test, or bypass security without our prior written permission;
• evade rate limits, overload the Service, scrape it, or use abusive or deceptive automation;
• reverse engineer or attempt to extract source code except to the limited extent the law permits;
• resell, sublicense, white-label, or provide the Service to third parties without written permission;
• remove proprietary notices or use Klearburn’s name or branding in a misleading way; or
• use an output as verified professional advice or as the sole basis for a legally significant decision.

Klearburn and its licensors own the Service, software, visual design, branding, documentation, templates, and underlying technology, excluding Customer Data and third-party materials. Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable right to use the Service during your subscription for your internal business purposes.

If you give us feedback or suggestions, you allow us to use them without restriction or payment, provided we do not identify you publicly without permission.

Each party may receive non-public information that a reasonable person would understand is confidential. The receiving party will use reasonable care to protect it, use it only for this relationship, and share it only with personnel and providers who need it and are bound to protect it. This does not cover information that becomes public without breach, was already lawfully known, is independently developed, or is lawfully received without confidentiality duties.

A party may disclose confidential information where law requires it and, when legally permitted, will give advance notice and disclose only what is required.

Klearburn is a planning and record-keeping aid. It does not provide accounting, bookkeeping, audit, tax, legal, investment, lending, payroll, or other regulated financial advice. AI-extracted fields, reconciliation matches, tax figures, foreign-exchange conversions, hiring-cost estimates, contract interpretations, models, forecasts, and runway calculations may be wrong or become outdated.

You remain responsible for your books, filings, payments, records, and decisions. Check outputs against original documents and current provider data, keep independent backups and source records, and consult a qualified professional before filing a return, signing or cancelling a contract, making a payment, hiring, investing, borrowing, or taking another material action.

To the fullest extent permitted by law, the Service is provided "as is" and "as available". We do not warrant that it will be uninterrupted, error-free, completely secure, compatible with every provider, or that imported data and AI output will be accurate or complete. We disclaim implied warranties and terms, including satisfactory quality, fitness for a particular purpose, and non-infringement, to the extent they can lawfully be disclaimed.

You may cancel the subscription through Settings → Billing and may stop using Klearburn at any time. Cancelling a subscription does not delete your account or Customer Data. Account deletion is separate: export anything you need, then contact legal@klearburn.com or follow the deletion method in the Privacy Policy.

Account deletion does not by itself cancel an external Autumn/Stripe subscription. Cancel in the billing portal first or ask us to coordinate cancellation and deletion. Deletion also does not remove files in your Google Drive or data retained independently by a connected provider.

We may suspend or terminate access immediately where reasonably necessary for non-payment, a security threat, unlawful conduct, material breach, provider or legal requirements, or risk to another user. Where the issue can be remedied, we will normally give notice and a reasonable opportunity to do so. If we end a paid Service without cause, we will give reasonable notice where practicable.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any liability that cannot lawfully be excluded or limited.

Subject to that sentence, Klearburn is not liable for indirect, incidental, special, exemplary, or consequential loss, or for lost profits, revenue, savings, goodwill, business opportunity, or data. We are not liable for losses caused by inaccurate source data, an output you did not reasonably review, your provider or credential, or a third-party service outside our reasonable control.

Subject to the same exceptions, Klearburn’s total aggregate liability arising from the Service or these Terms will not exceed the greater of US $100 and the Klearburn fees you paid or owed in the 12 months before the event giving rise to the claim. This cap does not include fees you pay directly to an AI, banking, or other third-party provider.

You will indemnify Klearburn against a third-party claim, damage, or reasonable cost arising from Customer Data you were not authorised to use, your unlawful or fraudulent use of the Service, or your material breach of Sections 4 or 8. We will give prompt notice, allow you reasonable control of the defence, and cooperate at your expense. You may not settle a claim in a way that admits fault by or imposes an obligation on Klearburn without our written consent.

Neither party is responsible for delay or failure caused by events it could not reasonably control, including widespread internet or cloud outages, provider API failures, natural disasters, war, civil disorder, labour disputes, government action, or utility failure. Payment obligations already due are not excused.

We may update these Terms for changes to the Service, providers, business, or law. We will post the new version and date and give reasonable advance notice of a material change. A material change applies from the date stated in the notice. If you do not agree, stop using the Service and cancel before it takes effect; continued use afterwards means you accept the revised Terms.

• These Terms and the documents they expressly incorporate are the entire agreement about the Service and replace earlier discussions about it.
• You may not assign these Terms without our written consent. We may assign them as part of a genuine merger, financing, reorganisation, or sale of the Service, with notice where required.
• A failure to enforce a term is not a waiver. A waiver must be in writing.
• If a term is unenforceable, it will be limited to the minimum extent necessary and the remaining terms will continue.
• Except where these Terms expressly say otherwise, no person other than you and Klearburn may enforce them under the Contracts (Rights of Third Parties) Act 1999.
• Notices may be sent electronically. Service and billing notices go to the email on your account; legal notices to Klearburn go to legal@klearburn.com.

These Terms and any non-contractual dispute are governed by the laws of England and Wales. Before filing a claim, each party will try in good faith for 30 days to resolve it after written notice. The courts of England and Wales have exclusive jurisdiction, except that either party may seek urgent protective relief in another court with authority to grant it and any mandatory statutory jurisdiction remains unaffected.
