Terms of Service

1. Provider, scope and effective date

These Terms of Service (the “Terms”) govern access to and use of TubeResearcher, a software-as-a-service research product available at tuberesearcher.com and related pages (the “Service”). The provider is Tim Leimkühler, trading as Leimkühler Data Consulting, Luise-Rinser-Str. 8, 47506 Neukirchen-Vluyn, Germany (“TubeResearcher”, “we”, “us” or “our”). Contact: support@tuberesearcher.com.

These Terms are effective as of 9 September 2026. Any individual or entity accessing the Service is referred to as “you” or the “Customer”. Additional terms presented for a particular plan, feature, trial, promotion or order form form part of the agreement. In the event of a conflict, an individually agreed order form takes precedence, followed by these Terms and then general product information.

2. Eligibility and authority

You must be at least 18 years old and legally capable of entering into a binding contract to create an account or purchase a subscription. The Service is not directed to children. By using the Service on behalf of a company or other organisation, you represent that you have authority to bind that organisation.

We may request reasonable information to verify eligibility, identity, authority, payment details, or compliance. We may refuse registration where objectively justified, including for security, fraud-prevention, sanctions, legal-compliance, capacity or prior-abuse reasons.

3. Accounts and account security

An account is required for most features. Authentication is provided through Clerk. You must provide accurate information, keep it current, protect your login credentials and devices, and promptly notify us of suspected unauthorised access. You are responsible for activity performed through your account to the extent that it is attributable to you.

Accounts are personal unless a team or business plan expressly permits multiple authorised members. You may not sell, transfer, share or make an account available to unauthorised persons. We may require re-authentication, reset sessions or apply reasonable security controls where necessary to protect the Service or its users.

4. Contract formation

Descriptions on the website are invitations to place an order and are not binding offers unless expressly stated otherwise. You submit a binding order by completing checkout and activating the button that clearly indicates an obligation to pay. A contract is formed when we expressly accept the order or enable the paid Service, whichever occurs first. We will provide confirmation on a durable medium, normally by email.

Before placing an order, you can review and correct your entries. The contract language is English. We do not separately make the complete contract text available through a public register; your checkout confirmation, these Terms and the plan information sent to you form the contractual record.

5. The Service

TubeResearcher analyses public information relating to YouTube channels, videos and competitors and uses research and artificial-intelligence tools to support content ideation, thumbnails, titles, hooks, scripts and channel strategy. Available functions, supported sources, limits and workflows depend on the selected plan and may evolve over time.

The Service is a research and decision-support tool. It does not publish to YouTube, access YouTube Studio, or require access to your YouTube account unless a future feature is separately described and authorised by you. You remain solely responsible for editorial, commercial and legal decisions and for reviewing all results before use or publication.

6. AI-generated and analytical results

The Service uses probabilistic artificial-intelligence systems, including services supplied by OpenAI. Results may be incomplete, inaccurate, outdated, offensive, non-unique or unsuitable for your purpose. Similar or identical results may be generated for other users. You must independently verify facts, rights, citations, recommendations and legal compliance.

We do not promise or guarantee views, click-through rates, audience growth, revenue, ranking, virality, monetisation, sponsorships or any other result. Forecasts, scores and recommendations are estimates, not statements of fact or professional advice. They must not be used as a substitute for legal, tax, financial, medical or other regulated professional advice.

7. Plans, usage allowances and fair use

Free and paid plans may include limits for AI research, channels, competitor channels, thumbnails, team members, API access or other resources. The limits and included features displayed at checkout or in the account at the time of purchase apply to the relevant billing period. Usage is measured by our systems in good faith. Unused recurring allowances expire at the end of the billing period and do not roll over unless expressly stated otherwise.

You may not circumvent limits, create multiple accounts to avoid restrictions, automate access beyond documented interfaces, resell access without permission, or use the Service in a manner that imposes an unreasonable or disproportionate load. We may rate-limit or temporarily restrict unusually intensive or abusive use. Material reductions to a paid plan during an ongoing billing period do not apply retroactively unless required for security, law or third-party platform compliance; mandatory consumer rights remain unaffected.

8. Prices, taxes and payment

Current prices, currency, billing interval, included features and any applicable taxes are shown before the order is submitted. Prices displayed to consumers include applicable taxes where legally required; otherwise taxes may be calculated at checkout based on the billing location. You must provide accurate billing information and are responsible for taxes that the law requires you to bear.

Payments and subscription management are processed by Stripe and available payment-method providers. We do not receive complete card details. You authorise Stripe and the applicable payment provider to charge the selected payment method for recurring fees, taxes and any expressly ordered additional usage. If payment fails, we may retry collection, request another payment method, restrict paid features or suspend the subscription after reasonable notice, subject to mandatory law.

9. Renewal, plan changes and cancellation

Paid subscriptions renew automatically for successive periods equal to the selected billing period until cancelled. You may cancel at any time without a notice period through Account → Billing or by contacting us at the email address above. Ordinary cancellation takes effect at the end of the already-paid billing period, and access continues until then unless you request immediate deletion or another mandatory remedy applies.

Upgrades may take effect immediately with a prorated charge. Downgrades normally take effect at the next renewal and may reduce allowances or access to features. If consumers can conclude a recurring paid contract on the website, an electronic cancellation function will be made continuously and easily accessible as required by applicable law. Statutory rights to extraordinary termination remain unaffected.

10. Voluntary refund policy

In addition to mandatory statutory rights, a first-time Customer may request a full refund for the initial paid subscription within 14 days after purchase if no more than 20% of the plan's AI Research allowance has been consumed. This voluntary policy does not apply to renewals, previously refunded accounts, custom work, separately purchased usage or misuse. We may use account and usage records to determine eligibility.

The voluntary refund policy does not restrict any statutory withdrawal, warranty, conformity, termination or reimbursement right. Where mandatory law grants broader rights, mandatory law prevails.

11. Statutory right of withdrawal for consumers

If you are a consumer, you generally have the right to withdraw from a distance contract within 14 days without giving a reason. The withdrawal period begins on the day the contract is concluded. To exercise the right, inform Tim Leimkühler, Leimkühler Data Consulting, Luise-Rinser-Str. 8, 47506 Neukirchen-Vluyn, Germany, email: support@tuberesearcher.com, by an unequivocal statement before the period expires. You may use the model form below, but this is not mandatory. During the statutory withdrawal period, you may also use the prominently available electronic withdrawal function on the website.

If you expressly request that the Service begin during the withdrawal period and then withdraw, you may be required to pay a proportionate amount for the service supplied up to the time of withdrawal, but only where the legal requirements for such payment are met. Any advance payment that must be reimbursed will be returned without undue delay and no later than 14 days after receipt of the withdrawal, using the same means of payment unless otherwise agreed and without additional fees.

12. Model withdrawal form

To: Tim Leimkühler, Leimkühler Data Consulting, Luise-Rinser-Str. 8, 47506 Neukirchen-Vluyn, Germany, support@tuberesearcher.com. I/We hereby give notice that I/We withdraw from my/our contract for the provision of the following service: [service/plan]. Ordered on: [date]. Name of consumer(s): [name]. Address of consumer(s): [address]. Signature of consumer(s), only if submitted on paper: [signature]. Date: [date]. Delete as appropriate.

13. Customer inputs and licences

You retain your rights in prompts, instructions, channel references and other material that you submit (“Customer Input”). You grant us and our processors a worldwide, non-exclusive, royalty-free licence for the term of the agreement to host, copy, transmit, process, adapt and otherwise use Customer Input solely as necessary to provide, secure, maintain and improve the Service, comply with law and enforce these Terms. Optional analytics or model-improvement use requiring consent will occur only on the stated legal basis.

You represent that you have the rights and lawful basis needed to provide Customer Input and instruct its processing. Do not submit trade secrets, confidential information you are not authorised to disclose, special-category personal data, payment-card data, passwords, private YouTube credentials, or content whose processing would violate law or third-party rights.

14. Ownership of the Service and outputs

TubeResearcher and its licensors retain all rights in the Service, software, interfaces, databases, designs, documentation, brands, methods, models, prompts, templates and aggregated or anonymised insights. Except for the limited right to use the Service under these Terms, no right is transferred to you.

As between you and us, and to the extent legally possible and owned by us, we grant you the right to use results generated specifically for you for lawful purposes. This does not transfer rights in the underlying Service, third-party content, public YouTube material or other users' inputs or outputs. We do not warrant that an output is protectable, exclusive or free of third-party rights. You are responsible for clearance before commercial use.

If you provide feedback, you grant us a perpetual, worldwide, transferable, sublicensable and royalty-free right to use it without restriction or obligation, provided that we do not publicly identify you without permission.

15. Acceptable use

You must not use the Service unlawfully or to infringe intellectual-property, privacy, publicity or other rights; generate or distribute deceptive, defamatory, harassing, hateful, sexually exploitative or otherwise unlawful material; impersonate others; facilitate spam, fraud, manipulation, malware, credential theft or platform abuse; extract personal data for surveillance or profiling without a lawful basis; reverse engineer or interfere with the Service except where mandatory law permits; scrape the Service; bypass security or usage controls; or use outputs without appropriate human review where errors could cause material harm.

You must comply with the terms and policies of platforms whose content or data you analyse or use. We may investigate suspected violations and preserve or disclose relevant information where legally permitted and reasonably necessary to protect rights, security, users or the public.

16. YouTube and third-party content

The Service may display or analyse public information and content originating from YouTube. Such content remains owned by its respective rights holders. Availability through YouTube or another public source does not itself grant permission to reproduce or commercially exploit content. You are responsible for obtaining any necessary permission and for complying with copyright, trademark, personality-right and platform requirements.

Where the Service uses YouTube API Services, your use is also subject to the YouTube Terms of Service. YouTube and Google may change, restrict or discontinue data, interfaces or policies at any time, which may affect the Service. TubeResearcher is independent and is not sponsored, endorsed by or affiliated with YouTube or Google.

17. Availability, maintenance and changes

We use reasonable efforts to provide the Service but do not promise uninterrupted, error-free or permanently available operation, any particular response time, or compatibility with every device or third-party platform. Maintenance, security incidents, internet failures, force majeure, capacity constraints and third-party changes may cause interruptions.

We may modify the Service to improve it, address security or legal requirements, prevent abuse, reflect technical developments or respond to third-party changes. For consumers receiving a digital service continuously, changes that go beyond what is necessary to maintain conformity and negatively affect access or use will be made only on a valid contractual basis, without additional cost, and with the information and remedies required by mandatory law.

18. Suspension and termination by us

We may immediately suspend access to the extent reasonably necessary where we suspect security compromise, fraud, unlawful use, material breach, danger to users or systems, non-payment, sanctions issues or a requirement imposed by law or a third-party platform. Where appropriate, we will state the reason and allow a reasonable opportunity to cure before termination. We may permanently terminate for an uncured material breach or for serious cause where continuation cannot reasonably be expected.

We may discontinue free plans or terminate free accounts on reasonable notice. We may ordinarily terminate a paid subscription at the end of its current billing period on reasonable notice. If we terminate a paid subscription without cause before the end of a prepaid period, we will refund the unused prepaid portion. Mandatory consumer remedies remain unaffected.

19. Statutory conformity rights and disclaimers

Consumers have mandatory statutory rights regarding digital products, including conformity, remedies and required security updates. Nothing in these Terms excludes or limits those rights. Any commercial guarantee applies only if expressly identified as such.

For business Customers, the Service is supplied as available and, to the fullest extent permitted by law, without guarantees beyond the agreed service description. We do not assume a procurement risk for continued access to third-party platforms, data, models or APIs and do not guarantee business results, legal compliance of Customer content, or suitability for a particular commercial purpose.

20. Liability

We are liable without limitation for intent and gross negligence; injury to life, body or health caused intentionally or negligently; fraudulently concealed defects; guarantees expressly assumed; and liability under the German Product Liability Act or other mandatory law.

For ordinary negligence, we are liable only for breach of a material contractual obligation whose performance is essential to the agreement and on which the Customer may normally rely. In that case, liability is limited to damage that was foreseeable and typical when the contract was concluded. Otherwise, liability for ordinary negligence is excluded to the extent permitted by law. The same limitations apply to our representatives and agents.

For business Customers only, liability for ordinary negligence under the preceding paragraph is additionally limited in aggregate to the fees paid or payable for the Service during the 12 months preceding the event giving rise to liability. This cap does not apply where the first paragraph requires unlimited liability. Claims for contributory fault, mitigation and statutory limitation remain unaffected.

21. Indemnity for business Customers

If you use the Service as a business, you will indemnify us against third-party claims, reasonable costs and damages finally awarded or agreed in settlement to the extent caused by your unlawful Customer Input, your infringement of third-party rights, or your material violation of Section 15. This obligation applies only to the extent you are responsible for the underlying conduct. We will promptly notify you and reasonably cooperate; we retain control of the defence where our own interests may be affected.

22. Data protection

Our Privacy Policy describes how we process personal data. If a business Customer submits personal data for which we act as a processor on its behalf, the parties will enter into a data-processing agreement where required. The Customer remains responsible for its own notices, lawful bases and instructions.

23. Changes to these Terms

We may amend these Terms for future contracts. For an existing continuing contract, we may make reasonable amendments where required by law, security, technical developments, new or changed features, third-party requirements or to close a regulatory gap, provided the change does not unreasonably alter the contractual balance. We will give reasonable advance notice in text form and explain material changes. Where consent is legally required, the change takes effect only with consent. Statutory termination rights remain unaffected.

24. Governing law and jurisdiction

German law applies, excluding the United Nations Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice does not deprive you of mandatory protections of the country in which you habitually reside. Consumers may bring proceedings in any court having jurisdiction under mandatory law.

If you are a merchant, a legal entity under public law, a special fund under public law, or have no general place of jurisdiction in Germany, the exclusive place of jurisdiction is the court having jurisdiction for Neukirchen-Vluyn, Germany, to the extent legally permitted.

25. Consumer dispute resolution, notices and severability

We are neither obliged nor willing to participate in dispute-resolution proceedings before a consumer arbitration board. The European Online Dispute Resolution platform was discontinued on 20 July 2025.

Contractual notices may be sent to support@tuberesearcher.com; cancellation and withdrawal remain possible through every channel required by mandatory law. If a provision of these Terms is invalid, the remaining provisions remain effective. The invalid provision is replaced only to the extent and in the manner provided by applicable law.
