Allgemeine Geschäftsbedingungen (AGB) für den Kauf von Toolyn-Lizenzen

Last updated: 8 November 2026

1. Who sells Toolyn

Toolyn licenses are sold by Amir Alayoubi, trading as Amiro, Hardtstraße 14, 76185 Karlsruhe, Germany (“we”, “us”). Email: contact@toolyn.app. These terms apply to every purchase of a Toolyn license on toolyn.app. The contract language is English.

2. What you buy

• A perpetual license to use Toolyn, the Windows app, on up to the number of PCs in the plan you choose: 1, 3 or 5 PCs at the same time.
• Updates are included. You get every update to Toolyn that we release, at no extra charge. There is no subscription.
• Toolyn is sold as early access: it is updated often while it grows toward version 1.0, and tools are added and improved over time. The early-access price is lower than the price from version 1.0; buyers who paid the early-access price keep their license and their updates.
• Toolyn runs on Windows 10 and Windows 11, 64-bit.

3. Prices and payment

Prices are in US dollars, one-time, as shown on toolyn.app and at checkout when you buy. They are final prices. As a small business (Kleinunternehmer) under § 19 of the German VAT Act, we do not charge VAT, so no VAT is shown on the price or the invoice: Gemäß § 19 UStG wird keine Umsatzsteuer berechnet.

Payment is processed by Stripe, with the payment methods shown at checkout. Stripe sends you a receipt.

4. How the contract is made

The plans on toolyn.app are not yet a binding offer. When you complete checkout and press the button to pay, you make a binding offer to buy the license you chose. The contract is concluded when your payment is confirmed and we show you your license key.

5. Delivery

Your license key is delivered instantly: it appears on screen right after you pay, and we email it to the address you entered at checkout. You download Toolyn from toolyn.app. If you lose your key, toolyn.app/license emails it to you again.

6. 14-day money-back promise

If Toolyn isn't for you, you get your money back in full, for any reason or none, within 14 days of buying. To claim it, email contact@toolyn.app from the address you bought with, or include your license key. We refund the full price to the payment method you used, through Stripe, without undue delay and at the latest within 14 days of your email. The refunded license is then withdrawn and stops activating Toolyn.

This promise is voluntary, and it covers the statutory right of withdrawal: it gives you at least the same 14 days and the same full refund, and we never ask you to give up that right when you start using Toolyn. Your statutory rights described below stay unaffected.

Right of withdrawal (for consumers)

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 the contract is concluded. To exercise it, tell us (Amir Alayoubi, Amiro, Hardtstraße 14, 76185 Karlsruhe, Germany, contact@toolyn.app) of your decision to withdraw by a clear statement, for example an email. You can use the model withdrawal form below, but you don't have to. To meet the deadline, it is enough to send your statement before the withdrawal period ends.

Effects of withdrawal. If you withdraw, we reimburse all payments we received from you without undue delay and at the latest within 14 days of the day we receive your withdrawal, using the same means of payment you used, unless we expressly agree otherwise. You will not be charged any fees for the reimbursement.

Model withdrawal form

7. Activation and fair use

• Toolyn asks for your license key the first time it starts and activates online once on each PC. After that it works offline; when it is online, it checks the activation from time to time in the background.
• A license is for the number of PCs in its plan. To move it to another PC, choose Deactivate this PC in Toolyn's Settings, under License. If a PC is lost or broken and you can't deactivate it, email us and we'll free the seat.
• Please keep your key to yourself and the PCs it is for: don't publish it or share it beyond them. We may withdraw a key that is published, used well beyond its plan, refunded or charged back. Where we can, we'll tell you by email first.

8. Warranty

The statutory warranty rights apply (for consumers in Germany, §§ 327 ff. of the German Civil Code for digital products). This includes the updates the law requires to keep Toolyn working as agreed. We don't promise a particular feature by a particular date.

9. Liability

We are liable without limitation for damage caused intentionally or through gross negligence, for injury to life, body or health, under the German Product Liability Act, and where we have given a guarantee. For slight negligence we are liable only for the breach of an obligation that is essential to the contract and on which you may rely, and then only for the foreseeable damage typical for this kind of contract. Beyond that, our liability is excluded as far as the law allows.

10. Governing law

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you buy as a consumer, this choice of law does not take away the protection of the mandatory consumer laws of the country where you live.

11. Dispute resolution

We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board. If something goes wrong, please write to contact@toolyn.app first: we'd rather fix it.
