General Terms & Conditions

These General Terms & Conditions ("GT&C") govern the contractual relationship between TJBERLIN UG (haftungsbeschränkt), trading as Ryggo, Kollwitzstrasse 51, 10405 Berlin, Germany ("Ryggo") and the business customer placing an order via ryggo.ai ("Buyer").

These GT&C apply exclusively to B2B transactions. By submitting an order, the Buyer confirms that they are acting in a professional or commercial capacity. These GT&C apply to both the Deploy & Decide programme and outright purchase orders, as described below.

Any conflicting or supplementary terms of the Buyer are not accepted unless Ryggo has expressly agreed to them in writing.

By submitting an order via ryggo.ai and accepting these GT&C, the Buyer enters into a contract of sale for the device(s) with Ryggo. Ryggo purchases the corresponding device(s) from the vendor named in the order confirmation (the "Vendor") and resells them to the Buyer, with the purchase and resale occurring simultaneously upon delivery. The Buyer is obliged to pay the invoice issued upon order submission, to Ryggo, within the payment period stated in Section 3.

Ryggo will confirm the order in writing by email to the address provided at checkout. Ryggo will send the supplying vendor a Fulfilment Release Note confirming the paid order upon receipt of payment. No delivery obligation arises until payment is received in full.

Ryggo is the Buyer's contracting party for the sale of the device, as well as for the platform and (where applicable) the Deploy & Decide programme. The device is shipped directly by the Vendor to the Buyer; Ryggo does not hold physical stock at any point.

The full order amount is due within 14 days of the invoice date. Payment is to be made by bank transfer to the account details stated on the invoice.

The invoice is issued at the time the order is submitted and sent to the email address provided. The order confirmation is sent separately upon receipt of payment.

If payment is not received by the due date, the Buyer is automatically in default without the need for a further reminder. Default interest accrues at 9 percentage points above the applicable base interest rate of the European Central Bank, in accordance with § 288 (2) BGB. Ryggo reserves the right to claim additional damages for late payment.

All prices are stated exclusive of VAT unless otherwise indicated. Applicable VAT will be shown on the invoice.

The Deploy & Decide programme allows the Buyer to evaluate 2, 4 or 6 exoskeleton devices in their own operation before committing to a permanent deployment. The programme operates as follows:

4.1 Order and payment. The Buyer pays the full device price at the time of ordering. This payment covers both the evaluation period and, if the deployment is successful, the purchase price of the device. No additional charges apply during the evaluation period.

4.2 Evaluation period. The evaluation period is 2 weeks (14 calendar days), 4 weeks (28 calendar days) or 8 weeks (56 calendar days), as selected by the Buyer at checkout. Public holidays are excluded from the count. The evaluation period begins on Day 1, defined as the date the device is confirmed as received and operational by the Buyer.

4.3 Outcome — successful deployment. If the Buyer elects to retain the device at the end of the evaluation period, the amount already paid constitutes the full purchase price. No further payment is required. Title to the device transfers from the vendor to Ryggo, and simultaneously from Ryggo to the Buyer, upon this election.

4.3a Retention of title. Throughout the evaluation period, title to the device remains with the vendor; no sale occurs during this time (Kauf auf Probe, §§454–455 BGB). No transfer of title occurs except as set out in 4.3 or 4.7, at which point title passes from the vendor to Ryggo and simultaneously from Ryggo to the Buyer. Where the Buyer returns the device under 4.4, title remains with the vendor throughout and no transfer to the Buyer occurs at any point.

4.4 Outcome — return. If the Buyer elects not to retain the device, the Buyer must notify Ryggo by email to support@ryggo.ai before the end of the evaluation period. The device must be returned to the vendor in its original condition within 5 business days of that notification. Return shipping is organised and paid by the Buyer. Risk of loss or damage to the device during return transit remains with the Buyer until the vendor confirms receipt in writing. Ryggo recommends that the Buyer arranges adequate insurance for the return shipment.

4.5 Refund. Upon confirmed receipt of the returned device by the vendor, Ryggo will refund the device price paid less the applicable evaluation fee. The evaluation fee is determined by the evaluation period selected at checkout: 25% of the device price for a 2-week programme, 30% for a 4-week programme, and 40% for an 8-week programme. Expressed as a refund: 75% of the device price is refunded for a 2-week programme, 70% for a 4-week programme, and 60% for an 8-week programme. The evaluation fee covers the cost of the evaluation period and any vendor handling. Refunds are processed within 14 days of confirmed return. For the avoidance of doubt, the refund applies to the device price only. Charges invoiced separately for delivery, training, or accessories are non-refundable.

4.6 Device condition and Buyer's duty of care. Throughout the evaluation period, the Buyer is solely responsible for the proper care and safekeeping of the device. The Buyer shall use the device strictly in accordance with the vendor's official user manual and intended use specifications. The user manual is available on the device's product page on ryggo.ai, where the vendor has made it available, or directly from the vendor. The device must be returned in the same condition as received, subject to fair wear and tear. All original components, accessories, and packaging must be included in the return. Damage beyond fair wear and tear, or missing parts or components, does not affect the Evaluation Fee, which remains non-refundable. The Buyer shall indemnify and hold Ryggo harmless against any claim, cost, or liability arising from damage to the device or missing parts occurring during the evaluation period or return transit.

4.7 No response. If Ryggo receives no notification from the Buyer by the end of the evaluation period, the deployment is considered successful and the purchase is deemed complete. Title to the device transfers from the vendor to Ryggo, and simultaneously from Ryggo to the Buyer, accordingly. Ryggo may, at its reasonable discretion, treat confirmation received shortly after the end of the evaluation period as valid — including where communicated informally by email or other means outside the platform — where the delay results from circumstances such as staff unavailability on the Buyer's side.

4.8 Damage and missing parts claims. Where the vendor confirms upon inspection that a returned device has been damaged beyond fair wear and tear, or that parts or components are missing, Ryggo will pass the vendor's documented claim to the Buyer. The Buyer is obliged to resolve the claim directly with the vendor within 14 days of notification. Ryggo reserves the right to deduct the vendor's confirmed repair or replacement costs from the refund amount prior to processing. Where the vendor's claim exceeds the refund amount, the Buyer remains liable for the excess. If the Buyer and vendor have not reached resolution within 14 days, Ryggo may process the refund net of the claimed amount and release the balance to the Buyer, without prejudice to any remaining claim the vendor may have against the Buyer.

For outright purchase orders, the full device price is due as described in Section 3. Upon receipt of payment, Ryggo will send the vendor a Fulfilment Release Note confirming the paid order. The vendor fulfils the order by delivering the device directly to the Buyer, on Ryggo's instruction, consistent with Section 2. Delivery lead times are typically 4–6 weeks from order confirmation; exact timelines are confirmed by the vendor and communicated to the Buyer.

Title to the device transfers from the vendor to Ryggo, and simultaneously from Ryggo to the Buyer, upon delivery (a back-to-back transfer — Ryggo does not hold title outside of this instantaneous transaction). Risk passes to the Buyer upon handover from the carrier to the Buyer.

Delivery is made to the shipping address provided at checkout. Shipment is arranged directly by the vendor. Tracking information and shipment details are provided by the vendor upon dispatch.

Delivery timelines are estimates and are not guaranteed. Ryggo is not liable for delays caused by the vendor or carrier. If a material delay occurs, Ryggo will inform the Buyer and work with the vendor to find a resolution.

Ryggo is the Buyer's contracting party for the sale of the device. Ryggo's warranty obligations to the Buyer follow applicable statutory sale-of-goods law. Device specifications, technical data, compatibility information, and any product warranty terms are provided by the vendor and form part of Ryggo's offer to the Buyer.

Ryggo fulfils its warranty obligations through the vendor: the vendor is responsible for inspection, repair, replacement, and any other warranty remedy, and Ryggo will pass any warranty or defect claim to the vendor for direct handling with the Buyer, unless otherwise agreed. Where the vendor fails to remedy a valid claim within a reasonable time, the Buyer's statutory remedies against Ryggo as the contracting seller remain available.

Product liability (Produkthaftung) for manufacturing or design defects rests with the vendor and manufacturer in accordance with applicable law. As between Ryggo and the vendor, the vendor indemnifies Ryggo against claims arising from the vendor's devices, in accordance with the Vendor Platform Agreement.

Ryggo's liability for damages arising from or in connection with an order is limited to the order value, except in cases of wilful misconduct or gross negligence, or where mandatory law provides otherwise.

Ryggo is not liable for indirect or consequential damages, including but not limited to loss of production, loss of profit, or operational disruption, unless caused by wilful misconduct.

The platform and the AI advisor are provided as tools to support the Buyer's decision-making. Final device selection and suitability assessment remains the responsibility of the Buyer.

Ryggo processes personal data provided during the ordering process in accordance with applicable data protection law, including the General Data Protection Regulation (GDPR). The Buyer's personal data is used solely for the purposes of order processing, communication, and fulfilment. Full details of how personal data is collected, used, and retained are set out in Ryggo's Privacy Policy, available at ryggo.ai/privacy.

Neither party shall be liable for failure or delay in performance caused by circumstances beyond their reasonable control, including but not limited to natural disasters, war, civil unrest, pandemic, government action, or vendor supply disruption. The affected party shall notify the other without undue delay. If the force majeure event continues for more than 30 days, either party may withdraw from the affected order without liability. Any amounts already paid for unfulfilled orders will be refunded in full.

If insolvency proceedings are opened against the Buyer, or if the Buyer is unable to meet its payment obligations, Ryggo reserves the right to withdraw from any pending order that has not yet been fulfilled, without liability. Any amounts already paid will be treated in accordance with applicable insolvency law.

Ryggo may update these GT&C at any time with 14 days' notice. The current version is always available at ryggo.ai/terms. Orders placed prior to the effective date of any update are governed by the version in force at the time of the order.

These GT&C and all orders placed via ryggo.ai are governed exclusively by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).

The place of jurisdiction for all disputes arising from or in connection with these GT&C is Berlin, Germany, to the extent permitted by law.
