Terms of Service

Last updated: 2 August 2026

These terms govern your use of Bigrank. Please read them carefully — they include important information on your subscription, your right of withdrawal as a consumer, and our liability.

01 Scope and provider

These Terms of Service (“Terms”) govern the use of the Bigrank application and related services (the “Service”) provided by:

Kevin Baum — 57Marketing
c/o Autorenglück #19414
Albert-Einstein-Straße 47
02977 Hoyerswerda
Germany

Email: hello@bigrank.io

These Terms apply to both consumers and businesses. A consumer (§ 13 BGB) is a natural person who enters into the contract for purposes outside their trade or self-employed professional activity; a business (§ 14 BGB) acts in the exercise of its trade or profession. Deviating terms of the customer do not apply unless we have expressly agreed to them in writing.

02 The Service

Bigrank is a software-as-a-service tool that performs SEO tasks for small businesses on autopilot: it researches keywords, generates articles and social posts using AI, and — where you connect a website — publishes them and tracks performance.

The specific functions and limits of each plan are those described in the app and on our pricing page at the time of your order. We provide the Service with the care of a diligent provider but do not owe a specific commercial result, such as particular search rankings or traffic figures (see “AI-generated content”).

03 Registration and account

Using the Service requires an account. You must provide accurate information and keep your login credentials confidential. You are responsible for activity carried out through your account. You must be at least 18 years old to register.

You may not share your account with unauthorised third parties. Please notify us without delay if you suspect misuse of your account.

04 Conclusion of contract

By selecting a plan and completing the order process, you submit a binding offer to conclude a contract. The contract is formed when we confirm your order or activate the Service for you. The order process, including the steps to correct input errors, is presented during checkout. The contract text is not stored by us in a separately retrievable form beyond your account records.

05 Plans, prices and payment

The prices are those stated in the order process at the time of your order. Unless stated otherwise, prices are shown including applicable statutory VAT for consumers.

Subscriptions are billed in advance for the chosen billing period (monthly or yearly) and renew automatically for the same period unless cancelled in time (see “Term and cancellation”).

Payments are handled by our merchant of record, Paddle, operated by Paddle.com Market Ltd (London, United Kingdom) and its affiliates, who act as the seller of record and process payment and billing on our behalf and in their own name for tax purposes. By completing a purchase you also accept Paddle’s applicable terms for the payment transaction. Accepted payment methods are shown during checkout.

06 Free trials and promotions

We offer a 14-day free trial. Unless stated otherwise at sign-up, the trial automatically converts into a paid subscription at the chosen plan price at the end of the 14-day period, unless you cancel before it ends. You can cancel during the trial at any time via your account settings, and no fee is charged if you cancel before the trial ends. Only one trial per customer may be used unless we allow otherwise. Any promotional pricing applies as stated at sign-up.

07 Term and cancellation

The contract runs for the billing period you select and renews automatically for a further period of the same length. There is no minimum term and no notice period: you can cancel at any time via your account settings or by emailing hello@bigrank.io. The cancellation takes effect at the end of the current billing period, and you keep access until then.

For contracts concluded online, consumers can also cancel using the cancellation option provided in the account (§ 312k BGB). The right to terminate for good cause remains unaffected for both parties. On termination, your access ends at the close of the paid period; already paid fees are not refunded except where legally required.

08 Right of withdrawal (consumers)

Consumers have a statutory right of withdrawal. The following applies to consumers.

Instructions on withdrawal

You have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period is 14 days from the day of the conclusion of the contract.

To exercise your right of withdrawal, you must inform us (Kevin Baum — 57Marketing, c/o Autorenglück #19414, Albert-Einstein-Straße 47, 02977 Hoyerswerda, Germany; hello@bigrank.io) of your decision by a clear statement (e.g. a letter or email). You may use the model withdrawal form below, but it is not obligatory. To meet the withdrawal deadline, it is sufficient to send your communication before the withdrawal period has expired.

Consequences of withdrawal

If you withdraw, we will reimburse all payments received from you without undue delay and no later than 14 days from the day we are informed. We use the same means of payment you used, unless expressly agreed otherwise; you will not be charged any fees for the reimbursement.

Early expiry of the right of withdrawal

If you expressly request that we begin providing the Service during the withdrawal period, you must pay a reasonable amount corresponding to the part already provided when you exercise the withdrawal. Your right of withdrawal expires prematurely once the contract has been fully performed and, for paid services, only if you expressly consented to the start of performance before the end of the withdrawal period and acknowledged that you thereby lose your right of withdrawal upon complete performance.

09 Your obligations and acceptable use

You agree not to use the Service to:

  • infringe the rights of others or applicable law (including copyright, trademark, competition, and data-protection law);
  • publish illegal, misleading, defamatory, or harmful content;
  • connect a website or account you are not authorised to manage; or
  • interfere with, overload, or attempt to gain unauthorised access to the Service.

You are responsible for the content you approve and publish and for ensuring you hold the necessary rights to your connected websites and any materials you provide.

10 Connected websites, content and rights

To provide the Service, you grant us the rights and access needed to read your connected website, generate content, and publish it on your behalf. You may revoke this access at any time by disconnecting the website.

As between you and us, the articles and posts generated for you through the Service are yours to use for your business, subject to your payment obligations. You warrant that any materials, brand assets, and website access you provide do not infringe third-party rights.

11 AI-generated content

The Service uses AI to generate text. AI output can be inaccurate, incomplete, or unintentionally similar to existing material, and search rankings depend on many factors outside our control. We therefore do not warrant any specific ranking, traffic, or commercial result, nor that generated content is free of errors. You are responsible for reviewing content before it is published; you can edit or disable automatic publishing at any time.

12 Availability and changes to the Service

We aim for high availability but do not guarantee uninterrupted access. Maintenance, updates, and factors outside our control may cause temporary interruptions. We may further develop, change, or discontinue features, provided the core functionality you paid for is not unreasonably impaired; material adverse changes will be communicated in advance where reasonable.

13 Warranty

The statutory warranty rights apply. For consumers, the statutory provisions on defects apply without restriction. For businesses, warranty claims are subject to the statutory limitation periods; obvious defects must be reported without undue delay.

14 Liability

We are liable without limitation for intent and gross negligence, for injury to life, body, or health, under the German Product Liability Act (Produkthaftungsgesetz), and to the extent we have assumed a guarantee.

For slight negligence, we are liable only for the breach of an essential contractual obligation (an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely), and in that case only for the foreseeable, contract-typical damage. Any further liability is excluded.

The above limitations also apply in favour of our legal representatives and vicarious agents. Mandatory statutory liability, including under data-protection law, remains unaffected.

15 Data protection

We process personal data in accordance with our Privacy Policy. Where we process personal data on your behalf (for example, data relating to your connected websites and their visitors), we will, on request, conclude a separate data processing agreement (Art. 28 GDPR) with you.

16 Changes to these Terms

We may amend these Terms where there is a valid reason (e.g. changes in the law or to the Service). We will notify you of material changes in text form at least 30 days before they take effect. If you do not object within that period, the changes are deemed accepted; we will inform you of this consequence in the notice. Your statutory right to terminate remains unaffected.

17 Final provisions

These Terms and the contractual relationship are governed by the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only to the extent that it does not deprive the consumer of the protection of the mandatory provisions of the law of their country of habitual residence.

If you are a merchant, a legal entity under public law, or a special fund under public law, the exclusive place of jurisdiction is our registered seat. For consumers, the statutory places of jurisdiction apply.

We are not obliged and generally not willing to participate in dispute resolution proceedings before a consumer arbitration board.

Should individual provisions of these Terms be or become invalid, the validity of the remaining provisions remains unaffected. This English text is provided for convenience; the parties may agree that the German version prevails.
