Legal
Terms of Service
These Terms of Service govern the use of GrowHelper and the purchase of paid subscriptions and token top-ups from Marvin Trilk, Eresburgstr. 46b, 12103 Berlin, Germany (the “Provider”).
Last updated: 16 July 2026
1. Scope and provider
These terms apply to the GrowHelper website and web application and to all digital services offered through them. The provider and contractual partner is Marvin Trilk, sole proprietor trading as GrowHelper, Eresburgstr. 46b, 12103 Berlin, Germany, email: info@grow-helper.com. Any conflicting user terms apply only if expressly accepted by the Provider.
2. Service
GrowHelper is a digital documentation and information platform for plant cultivation. The platform may provide equipment and grow management, strain management, AI chat, context-aware guidance, image analysis and OCR functions. The available features are described in the current product and plan information. GrowHelper is required to provide the agreed digital functions but does not guarantee a particular cultivation result, yield or error-free AI output.
3. AI output and professional responsibility
AI-generated responses, image analyses and OCR results are produced automatically and may be incomplete, misleading or incorrect despite careful technical design. They do not constitute binding professional, medical, legal or regulatory advice. Users must independently verify information and recommendations before implementation, particularly in relation to plant disease, pest control, electrical equipment, nutrients or other safety-related measures. GrowHelper is not a medical device and must not be used to diagnose or make decisions about human health.
4. Adult and lawful use
GrowHelper is intended solely for people aged 18 or over. It may only be used where such use is lawful at the user's place of residence and use. Users are responsible for complying with all applicable laws and regulations, particularly those relating to cannabis, youth protection, data protection, copyright, plant protection, electrical safety and chemicals. GrowHelper does not encourage unlawful cultivation or any other criminal offence.
5. Registration and account
The app currently requires an account created through Google Sign-In. Registration details must be accurate. Account access and devices must be protected appropriately. An account may generally be used only by the registered person and may not be sold, transferred or shared with third parties. Users must notify the Provider without delay if unauthorised access is suspected. The Provider may temporarily suspend an account where there are specific indications of misuse, security risks or material breaches of contract.
6. Formation of the contract
The free contract is formed when registration is completed and the account is activated. For paid subscriptions or top-ups, the presentation in GrowHelper or Stripe Checkout is not yet a binding offer. After selecting a paid product, you are redirected to Stripe Checkout. The contract is formed when the user submits the paid order there through a button that clearly indicates the obligation to pay and the order is subsequently accepted by confirmation or activation. Before ordering, the essential service characteristics, total price, term, cancellation conditions and any additional costs are displayed. The contract confirmation, applicable terms and withdrawal information are provided on a durable medium, normally by email.
7. Prices and payment
GrowHelper is currently offered as Free at €0.00 per month, Premium at €9.99 per month and Pro at €19.99 per month. Due to the application of the German small-business VAT exemption under section 19 UStG, VAT is neither charged nor shown separately. The final prices displayed in Stripe Checkout before the order is submitted apply. Payment processing is provided through Stripe; the payment methods available at the time are displayed in the checkout. Payments are due when the contract is formed or at the start of the relevant billing period. Stripe may provide its own terms and privacy information in connection with payment processing. If a payment fails or is reversed, the Provider may, after appropriate notice, restrict access to paid features until the issue is resolved.
8. Plans, usage limits and token budgets
Plans differ in particular in the monthly AI token budget, the size of the active chat context and the number of grows, locations, strains and chats that can be used simultaneously. Current monthly AI budgets are: Free 50,000 tokens, Premium 2,000,000 tokens and Pro 5,000,000 tokens. The active AI context per chat is currently up to 10,000 tokens on Free and up to 150,000 tokens on Premium and Pro. The complete service limits displayed on the pricing or checkout page when the contract is formed become part of the contract. Tokens are technical usage units and not currency. Actual consumption may vary depending on the model, text length, history, images, documents and context. Estimates are non-binding approximations.
9. Monthly budget and token top-ups
The regular monthly token budget is renewed at the start of each billing period. Unused monthly budget tokens are not carried over. Only users with an active Premium or Pro plan may, where offered, purchase and use additional token top-ups. The available top-up quantities and prices are displayed before purchase; quantities between 1,000,000 and 10,000,000 tokens may currently be offered. Top-up tokens are used only after the regular monthly budget is exhausted and remain associated with the account until used. If the account is downgraded to Free, an existing top-up balance remains stored but cannot be used. It is made available again when Premium or Pro is reactivated. Top-ups are account-specific, non-transferable and cannot be redeemed for cash. Statutory withdrawal, refund and conformity rights remain unaffected.
10. Term, renewal and cancellation
Paid subscriptions run for one month and automatically renew for another month unless cancelled before the end of the current billing period. Within the app, a subscription can be managed and cancelled with effect from the end of the current billing period through “Subscription & Tokens” and “Manage Subscription” in the Stripe Customer Portal. Payment information and payment history can also be viewed or managed there. In addition, the Provider makes available on the public website a legally compliant cancellation function that leads directly to a cancellation and confirmation page; the cancellation is confirmed electronically. Ordinary cancellation does not generally result in a pro-rata refund of amounts already paid; statutory rights, including withdrawal, price reduction, reimbursement and damages, remain unaffected. Following cancellation, the paid plan remains active until the end of the billing period already paid for. Account deletion and cancellation of a paid subscription must be technically linked so that no further fees are charged without an ongoing contract.
11. Downgrades and locked content
Following a downgrade, the limits of the new plan apply from the next billing period. Where stored grows, locations, strains or chats exceed the new active limits, older or less recent items may be temporarily locked. They generally remain stored and become accessible again after a corresponding upgrade, provided they have not been deleted by the user or deletion is otherwise lawfully required. The product will indicate which items are active and which are locked.
12. User content and necessary rights
Users retain their rights in uploaded text, images and documents. For the duration of the contract, users grant the Provider a non-exclusive, worldwide right limited to the contractual purpose to store, technically reproduce, format, transmit and have such content processed by service providers where necessary to provide GrowHelper. Users confirm that they are authorised to use and transmit the content and that it does not infringe third-party rights. Personal data relating to third parties may be uploaded only where a sufficient legal basis exists. Identity documents, health records, medical diagnoses and other highly sensitive personal data should not be uploaded.
13. Prohibited use
Prohibited activities include unlawful content or conduct, infringement of copyright, trade marks, personality or data protection rights, malware, automated mass requests, circumvention of plan, security or access restrictions, resale or public provision of the service without permission, abusive API use, manipulation of billing or token systems and conduct that disrupts the platform or other users. For material or repeated breaches, the Provider may restrict access or terminate the contract after prior warning. Immediate suspension is possible in the event of serious security risks, criminal conduct or manifestly unlawful content.
14. Availability, maintenance and third parties
The Provider aims for high availability but does not guarantee uninterrupted or entirely error-free access. Temporary restrictions may result from maintenance, security updates, technical failures, force majeure or outages affecting hosting, Firebase, Google Gemini, payment or network providers. Planned material maintenance will be announced where reasonably possible. Statutory rights concerning defective digital products and statutory update and supply obligations remain unaffected.
15. Changes to services, terms and prices
The Provider may further develop GrowHelper and adjust features where there is an objective reason, such as technical development, security, abuse prevention, changes to third-party services or legal requirements. Material adverse changes to an ongoing paid service will be made only in accordance with applicable law. Subscription price changes apply no earlier than a future billing period and are communicated in advance. Users may cancel before the change takes effect. Changes to these terms take effect only where legally permitted and after appropriate notice.
16. Conformity and liability
The statutory rules governing digital products apply. The Provider has unlimited liability for intent and gross negligence, culpable injury to life, body or health, liability under product liability law and expressly assumed guarantees. In cases of ordinary negligence, the Provider is liable only for breach of a material contractual obligation; in that case liability is limited to the damage typically foreseeable when the contract was formed. A material obligation is one whose performance is necessary for proper performance of the contract and on which users may regularly rely. Mandatory consumer rights remain unaffected.
17. Consumer right of withdrawal
Consumers generally have the right to withdraw from a paid distance contract within fourteen days from the date the contract is formed without giving reasons. To exercise the right, a clear statement must be sent to Marvin Trilk, Eresburgstr. 46b, 12103 Berlin, Germany, email: info@grow-helper.com. Sending the notice before the deadline is sufficient. In the event of withdrawal, payments received are generally refunded within fourteen days of receiving the withdrawal notice using the same payment method, unless the law provides otherwise. If the consumer expressly requested that the digital service begin during the withdrawal period, proportionate payment may be due for the part supplied before withdrawal where the statutory requirements are met. The right of withdrawal for a paid service does not expire merely because of the first login or first use, but only under the statutory conditions. Withdrawal information must be provided before the contract is formed and with the contract confirmation on a durable medium.
18. Model withdrawal form
If you wish to withdraw from the contract, you may use the following statement and send it to Marvin Trilk, Eresburgstr. 46b, 12103 Berlin, Germany, email: info@grow-helper.com: I hereby withdraw from the contract concluded by me for the provision of the following digital service: Ordered on: Name of consumer: Address of consumer: Email address of the GrowHelper account: Date: Signature, only if submitted on paper:
19. Termination by the Provider
The Provider may terminate free contracts with reasonable notice unless the user has a legitimate interest in continuation. Both parties retain the right to terminate for good cause. Before suspension or termination due to a remediable breach, a reasonable period to remedy the breach will generally be provided. Following termination, users may request access to data they supplied in accordance with applicable law. Statutory retention requirements remain unaffected.
20. Data protection
Information on the processing of personal data, Firebase, Google Sign-In, Google Gemini, images, documents, payment data and data subject rights is provided in the GrowHelper Privacy Policy. The Privacy Policy is not part of these Terms but fulfils statutory transparency obligations.
21. Consumer dispute resolution
The Provider is neither willing nor legally required to participate in dispute resolution proceedings before a consumer arbitration body.
22. Governing law and jurisdiction
German law applies, 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 them of the protection of mandatory rules of the country of their habitual residence. Exclusive jurisdiction in Berlin is agreed only with merchants, legal entities under public law or special funds under public law where legally permitted.
23. Final provisions
If an individual provision of these terms is or becomes wholly or partly invalid, the legal consequences are determined by statutory law. The remaining provisions remain effective. Individual agreements and separately negotiated terms take precedence over these standard terms.
