As of February 20, 2026
These General Terms and Conditions ("GTC") govern the use of the online service "Radicull" (web app at radicull.app) by users ("Users").
By registering, using, or purchasing a plan, you accept these GTC. Mandatory statutory rights (e.g., consumer protection law) remain unaffected.
Provider and contractual partner is:
Jonah Regez, Konradsweg 32, 8832 Wilen bei Wollerau, Switzerland
Email: info@radicull.app
Phone: 076 683 28 28
"Service": all functions of Radicull (dashboard, analysis, history, billing).
"Content": files uploaded by users, texts extracted from them, and inputs (e.g., learning objective, exam date).
"Results": AI-generated outputs (e.g., Important/Neutral/Ignore, justifications, questions).
"Consumer": a natural person who acts for purposes that are predominantly outside their trade, business, or self-employed professional activity.
"Entrepreneur": a natural or legal person who, at the time of conclusion of the contract, acts in the exercise of their trade, business, or self-employed professional activity.
Radicull supports learning organization by evaluating and prioritizing uploaded learning materials using AI.
No promise of success: Radicull does not guarantee exam success, completeness, or correctness of results.
Automated content: results are generated automatically and may contain errors; they do not replace your own subject-matter review.
Not for high-risk decisions: the service is not intended for medical, legal, or safety-critical decisions.
You undertake not to upload particularly sensitive personal data or confidential third-party information unless you have explicit authorization/consent to do so.
A user account is required to use essential functions. Authentication is carried out via Supabase (email/password) and optionally via Google login.
You are obligated to keep your access credentials confidential and to report unauthorized use immediately.
You must provide truthful information during registration and use.
Minimum age: use is permitted only for persons who are at least 16 years old. Minors aged 16 and above require, where required under applicable law, the consent of their legal representative.
In principle, you can delete your account at any time in the app or request deletion by email (see Privacy Policy on data deletion).
If you purchase a paid plan, a contract for paid use of the service is concluded. The order process is structured as follows:
Selection of the desired plan in the dashboard (Rescue, Steady, Secure).
Redirection to the checkout of our payment service provider (Stripe).
Review of your entries (plan, price, term, payment data) and possibility to correct input errors in the checkout before submitting the order requiring payment.
Completion of the order by confirmation in Stripe checkout (click requiring payment).
Immediate electronic confirmation (e.g., by email) and/or activation of the plan in your account. Only then do we accept your offer and the contract is concluded.
We store the contract text (plan, term, price) in your account or in the confirmation emails. Contract language is German.
You may use the service only in accordance with applicable laws and these GTC. In particular, it is prohibited to upload or process content
for which you do not hold rights (e.g., copyrighted materials without permission),
that infringes personality rights or data protection rights of third parties (e.g., private data of other persons without consent),
that is unlawful, insulting, discriminatory, or harmful, or
that contains malware or is aimed at attacks/circumvention of security measures.
You shall indemnify us against third-party claims asserted against us based on your content or your use, provided you are responsible for the infringement (including reasonable legal defense costs).
Temporary processing: uploaded files are processed server-side only for text extraction and analysis and are then deleted (no permanent file storage).
Result storage: analysis results can be stored in your history so you can access them later. You can delete stored analyses in the app.
No guarantee: results may be incomplete or erroneous; you remain responsible for your learning and your decisions.
Rights in user content: you remain the owner of all rights in your content. However, you grant us the non-exclusive, worldwide right, limited to the duration of the contract, to process your content for the purpose of contract performance, to reproduce it (as technically required), and to transmit it to engaged service providers (processors). This right ends as soon as the respective content no longer needs to be processed (e.g., after deletion of the analysis/account), subject to statutory retention obligations.
The current prices and service features are displayed in the dashboard and form part of the contract.
In the Free plan, you receive a limited number of analyses (currently: 1 analysis as starting credit). The scope may be changed.
Rescue is a one-time purchase (currently CHF 3) with a limited term (currently 7 days). Access ends automatically after the term expires, without notice of termination.
Steady and Secure are subscriptions (currently CHF 8/month for Steady and CHF 76/year for Secure). They renew automatically for the respective term (month/year) unless you cancel before expiry.
We may adjust prices for future billing periods. For subscriptions, we will inform you in due time before they take effect. If you do not agree, you can cancel before they take effect.
To ensure stable operation, technical limits may apply (e.g., maximum file sizes, number of files per analysis, prompt context length up to 128k tokens). Such limits are implemented in the service and may be adjusted where this is required for fair and secure operation.
Payments are processed via Stripe. Payment data (e.g., credit card numbers) is not stored by Radicull; Stripe processes this data under its own responsibility in accordance with its terms. Depending on your location, taxes/VAT may apply and be shown in checkout.
In case of default in payment or failed payment, we may temporarily suspend access to paid features until payment is successful.
Rescue: no cancellation required; ends automatically after expiry.
Steady/Secure: cancellation possible at any time in your account/via subscription management; cancellation takes effect at the end of the current billing period.
We may block or terminate accounts if there is good cause (e.g., abuse, legal violation, default in payment).
Upon termination, your right of access to paid features expires. You can export or delete saved analyses before termination. After account deletion, saved analyses are removed within a reasonable period unless there is a statutory retention obligation.
A refund is granted only if required by law or if we expressly promise this as a gesture of goodwill in an individual case. Periods/services already used may be taken into account on a pro rata basis. Mandatory consumer rights remain unaffected.
If you are a consumer in the European Economic Area (EEA) and a distance contract exists, you generally have a right of withdrawal. Details are governed by statutory provisions (e.g., Sections 312g, 355, 356 BGB in Germany).
Withdrawal period: 14 days from conclusion of the contract.
To exercise your right of withdrawal, you must inform us (email to info@radicull.app or by post to the address stated above) by means of an unambiguous declaration.
If you request that we begin performance during the withdrawal period, withdrawal may give rise to an obligation to pay compensation for value for services already provided. The right of withdrawal may expire upon complete performance of the contract under the statutory conditions.
If you wish to withdraw from the contract, please complete this form and return it:
To: Jonah Regez, Konradsweg 32, 8832 Wilen bei Wollerau, Switzerland, Email: info@radicull.app

We strive for high availability but do not owe uninterrupted availability. Maintenance, security measures, or disruptions may lead to outages.
We may further develop, adapt, or change functions of the service, provided that the purpose of the contract is not unreasonably impaired thereby. In the event of substantial changes, we will inform you within a reasonable period.
All rights to Radicull (software, design, trademarks, content) remain with us or our licensors. You receive a simple, non-transferable right of use for the duration of the contract, limited to the intended use of the service.
We are liable without limitation in cases of intent and gross negligence as well as in cases of injury to life, body, or health. In cases of ordinary negligence, we are liable only for breach of essential contractual obligations (cardinal obligations) and limited to the typical, foreseeable damage under the contract. Otherwise, liability is excluded to the extent permitted by law.
Liability for indirect damages, lost profit, or data loss is excluded to the extent permitted by law. You are obligated to make appropriate data backups (e.g., export important results).
We are not obligated and generally not willing to participate in dispute resolution proceedings before a consumer arbitration board. Note: the EU online dispute resolution platform (ODR) has been discontinued.
Information on the processing of personal data can be found in the Radicull Privacy Policy.
Swiss law applies to the exclusion of conflict-of-laws rules. Mandatory consumer protection provisions of the state in which you, as a consumer, have your habitual residence remain unaffected.
Place of jurisdiction for all disputes is, to the extent legally permissible, Wollerau (Schwyz), Switzerland.
Should individual provisions be or become invalid, the validity of the remaining provisions shall remain unaffected (severability clause).
We may amend these GTC for an objective reason (e.g., changes in law, functional changes). We will inform you of substantial changes in due time; rights of objection and termination remain unaffected.
