As of: May 2026
The legally binding version of these Terms is the German version available at /de/nutzungsbedingungen. In case of conflict, the German version prevails.
§ 1 Scope
These Terms of Use govern the use of the "PPL Monkey" learning platform (the "Platform"), operated by 21Solutions GmbH, Feldbergstraße 35, 60323 Frankfurt am Main, Germany (the "Provider"). They apply to all users, whether acting as consumers (§ 13 BGB) or entrepreneurs (§ 14 BGB).
§ 2 Service description
The Platform provides structured theory study content for the EASA PPL(A) theory exam in German and English.
- Public learning content is currently free of charge.
- Paid premium features will be offered via Stripe Checkout. Before contract conclusion the essential characteristics, total price including statutory VAT, payment methods and any duration will be clearly stated. The order is placed by clicking the button labelled "order with obligation to pay" (or equivalent). An invoice is sent by email (via Resend).
§ 3 Access and registration
Learning content may be read without registration to the extent provided on the Platform. Certain features (progress tracking, premium content, editor/admin area) require registration. Users must provide true and complete information and keep their credentials confidential. The minimum age is 16 years; younger persons may only use the Platform with the consent of a legal guardian.
§ 4 Usage rights
All content (text, graphics, data structures, code) is protected by copyright. The Provider grants users a simple, non-transferable, non-exclusive right to personal, non-commercial use of the content for their own exam preparation. Any further use — in particular reproduction, redistribution, commercial exploitation as well as automated processing (scraping) and the training of generative AI models — requires the Provider's prior written consent. A reservation against text and data mining pursuant to § 44b (3) UrhG is hereby expressly declared.
§ 5 User obligations and account suspension
Users undertake not to impair the availability or security of the Platform, not to circumvent security mechanisms, not to upload or distribute unlawful content, and to keep their credentials confidential. The Provider may suspend or close accounts in case of serious or repeated breaches. Further claims remain unaffected.
§ 6 Safety disclaimer — important safety notice
The content provided on PPL Monkey is intended solely as preparation material for the EASA PPL(A) theory exam and does NOT replace the official EASA syllabus or theoretical and practical training at an approved flight school (ATO or DTO). No warranty is given regarding completeness, timeliness or accuracy.
The content is not an operational instruction, not an official source, and is no substitute for AIP, NOTAM, the Aircraft Flight Manual (AFM/POH), checklists or the instructions of a qualified flight instructor. Only the current official documents and the decisions of the pilot-in-command (PIC) are authoritative.
Users remain solely responsible for their exam preparation, the conduct of flights and compliance with all aviation regulations. To the maximum extent permitted by law, the Provider accepts no liability for any damage of any kind — including property damage, financial loss, personal injury, serious injury or death — arising directly or indirectly from the application of the content provided in actual flight operations or flight preparation. By using the Platform, users confirm that they have understood and accepted this disclaimer.
§ 7 Right of withdrawal for paid content
Consumers have a statutory 14-day right of withdrawal for paid contracts. Details and the model withdrawal form are set out in our separate Cancellation Policy.
For digital content (e.g. premium access unlocked immediately upon purchase), the right of withdrawal expires early pursuant to § 356 (5) BGB if the consumer expressly consents prior to performance and acknowledges loss of the right. We collect this declaration actively in checkout.
§ 8 Availability
The Provider endeavours to keep the Platform continuously available but does not guarantee uninterrupted accessibility. Maintenance, security or technical work may cause temporary limitations.
§ 9 Liability
The Provider is liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act, and within the scope of a guarantee assumed. For slight negligence regarding material contractual obligations (cardinal duties), liability is limited to the foreseeable damage typical for the contract. Otherwise — to the extent permitted by law — liability is excluded. § 6 (safety disclaimer for application of content in flight operations) remains unaffected.
§ 10 Data protection
Our Privacy Policy applies.
§ 11 Changes to the Terms
The Provider may amend these Terms with effect for the future where required by changes in law, case law, technical requirements or platform features. Registered users will be informed of material changes by email at least six weeks before they take effect. If the user does not object in text form within this period, the changes are deemed accepted; this consequence will be pointed out in the change notice. In case of objection, either party may terminate the contractual relationship with effect from the date the changes take effect.
§ 12 Dispute resolution
The European Commission provides an ODR platform: https://ec.europa.eu/consumers/odr/. We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.
§ 13 Final provisions
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only insofar as it does not deprive the consumer of the protection afforded by mandatory provisions of the law of their habitual residence. Exclusive place of jurisdiction for disputes with merchants, legal entities under public law and special funds under public law is Frankfurt am Main. Should individual provisions be invalid, the statutory provisions shall apply in their place; the validity of the remaining provisions remains unaffected.
