AppThunder Referrals — Additional Terms

Last updated: September 30, 2026

These Additional Terms govern the use of AppThunder Referrals ("Referrals"), a service of AMDMarketing (sole proprietor: Alejandro Morillo Diaz), Am Markt 14, 23769 Fehmarn, Germany ("the Company", "We", "Us"). They apply in addition to Our Terms and Conditions at https://appthunder.io/terms ("General Terms"). Where these Additional Terms and the General Terms conflict, these Additional Terms prevail for Referrals. Capitalised terms not defined here have the meaning given in the General Terms.

The following sections of the General Terms do not apply to Referrals, because they concern the app-generation service only: "Plans, Build Credits and Orders", "Right of Withdrawal for Consumers", "Refund Policy", "User Content and Your Website", "Generated Applications — Ownership and License" and "Application Store Submission".

1. Business customers only

Referrals is offered exclusively to entrepreneurs within the meaning of § 14 of the German Civil Code (BGB), i.e. natural or legal persons who order in the exercise of their commercial or independent professional activity. Referrals is not offered to consumers. By creating a Referrals subscription You confirm that You are acting as an entrepreneur. Statutory withdrawal rights for consumers therefore do not apply.

2. The service

Referrals lets You run a referral program for Your own app or web product. You create one or more programs in the Application, define each program's commission rule (a percentage of each payment for a set number of months, or a fixed amount per conversion), and send Us the data needed to attribute referrals and purchases — through the subscription-platform webhook, a Stripe webhook, the REST API, the copy-paste code templates or the web snippet ("Integrations").

Based on the data We receive, Referrals generates referral codes, attributes referred users to referrers, calculates commissions, applies Your hold period, voids commissions for refunds reported to Us, and shows the results in the Application and as exports (e.g. CSV, PayPal Mass Pay, Wise batch).

Attribution is deterministic: a referral is only counted when a referral code reaches Us through an Integration. We do not use fingerprinting or probabilistic matching. Figures in the Application are calculations based solely on the data You and Your systems send Us. They are not a statement of what You legally owe anyone.

3. No payment services

We never receive, hold, forward or pay out money on Your behalf or on behalf of Your referrers, and We do not initiate payments. All payouts to Your referrers are made by You, outside Referrals, using the payment provider of Your choice. Exports are an aid for making those payments; You must check them before You pay.

You are solely responsible for the rewards You promise, for paying them, and for any taxes, social-security contributions, invoicing, reporting or withholding obligations connected with them.

4. Your responsibilities

  • Program terms: You set and publish the terms of Your referral program towards Your referrers and referred users (eligibility, rewards, conditions, duration) and You are the only party bound by them.
  • Lawful promotion: You and Your referrers must not use Referrals for unsolicited advertising (e.g. e-mails or messages sent to people who have not consented). We do not send invitations or any other messages to referrers or referred users.
  • Platform rules: You are responsible for complying with the rules of the app stores and platforms You use, including their rules on incentives for downloads, reviews or sign-ups.
  • Data protection: You are the controller for the personal data of Your end users that You send to Referrals. You must have a legal basis for it, inform Your end users (e.g. in Your privacy policy), and obtain any consent that is required — including, where applicable, for storing a referral code on the end user's device via the web snippet. We process this data on Your behalf under the Data Processing Agreement (see section 9).
  • Data minimisation: only send the data Referrals needs. Use Your own user IDs (not names or plaintext e-mail addresses) as identifiers; if You send e-mail addresses, they are stored only as hashes. Do not put personal data into free-text fields beyond what the field is meant for.
  • Keys and accounts: keep Your secret keys (sk_aff_…) confidential and use them only on Your servers. You are responsible for all requests made with Your keys and for all activity in Your Account. Tell Us without delay if You suspect a key has been compromised, and rotate it.
  • Accurate data: You are responsible for the correctness and completeness of the data Your systems send (e.g. purchase amounts, refunds, user IDs).

5. Prices and payment

Referrals costs EUR 19 per month per Account, plus the statutory value-added tax (VAT) where applicable. One subscription covers all programs in Your Account. There is no revenue share and no cap on the referral revenue You track. Creating an Account and a program is free; an active subscription is required before the first referral code can be created.

The subscription is billed monthly in advance through Stripe Managed Payments. For these payments, Stripe (through its Link service) acts as merchant of record and calculates, collects and remits the applicable VAT or sales tax; Stripe's and Link's terms apply to the payment transaction. By subscribing, You authorise the monthly charge to Your chosen payment method until You cancel.

We may change the price with at least 30 days' notice by e-mail. A price change applies from the first billing period that starts after the notice period. If You do not agree, You may cancel before the change takes effect.

6. Term and cancellation

The subscription runs month to month. You can cancel at any time with the cancellation button in the Referrals settings of Your Account; cancellation takes effect at the end of the current billing period, and no further payment is charged. Fees already paid are not refunded, except where the law requires it.

We may terminate the subscription with 30 days' notice to the end of a billing period. Either party may terminate for good cause without notice; good cause for Us includes, in particular, use of Referrals for unlawful purposes, unsolicited advertising, misuse of the API, or payment default.

When the subscription ends, You can no longer create referral codes; Your programs and data remain available in Your Account for export. Deletion and return of data are governed by the Data Processing Agreement.

7. Availability and changes to the service

We aim for high availability but do not guarantee uninterrupted operation. Maintenance, faults at hosting or platform providers, or delayed or missing webhooks from third parties (e.g. Your subscription platform or Stripe) can delay or prevent the processing of events. We may further develop Referrals, including the API and Integrations; where a change removes functionality You rely on, We will give reasonable advance notice.

8. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act, and where We have given a guarantee. For slightly negligent breach of an obligation that is essential for achieving the purpose of the contract and on whose fulfilment You may regularly rely (a "cardinal obligation"), Our liability is limited to the foreseeable damage typical for this type of contract. Otherwise, Our liability for slight negligence is excluded.

Where liability is limited to foreseeable, typical damage, it is capped per contract year at the fees You paid for Referrals in the twelve months before the event giving rise to the claim. We are not liable for commissions, payouts or other payments that You make on the basis of figures that result from incorrect, incomplete or delayed data sent by You, Your systems or third-party platforms.

9. Data Processing Agreement

The Data Processing Agreement pursuant to Art. 28 GDPR at https://appthunder.io/dpa forms part of these Additional Terms and applies to all personal data We process on Your behalf in Referrals. By accepting these Additional Terms You also conclude that agreement.

10. Changes to these Additional Terms

We may amend these Additional Terms with at least 30 days' notice by e-mail, stating the changes. The amendment is deemed accepted if You do not object before it takes effect; We will point this out in the notice. If You object, either party may terminate the subscription as of the date the amendment would take effect.

11. Governing law and place of jurisdiction

These Additional Terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). If You are a merchant (Kaufmann), a legal entity under public law or a special fund under public law, or have no general place of jurisdiction in Germany, the exclusive place of jurisdiction for all disputes arising from this contract is the Company's place of business; We may also sue You at Your general place of jurisdiction.
