Terms and Conditions

Last Updated: August 14, 2026

1. Scope & Operator

These General Terms and Conditions of Sale ("Terms") govern every purchase of DaVinci Deluxe · Cloud Edition software licenses, subscriptions, tokens, credits and digital goods made through this website (davincideluxe.fr and its country domains). By ordering, subscribing or activating our software you accept these Terms in full.

DaVinci Deluxe · Cloud Edition is a brand operated by TechLT (techlt.net, [email protected]). All customer support is provided at [email protected].

2. Products & Licenses

DaVinci Deluxe · Cloud Edition is a professional, cloud-based automotive ECU tuning and file-processing service. Purchasing grants you a personal, non-exclusive, non-transferable right to use the software and services on the terms of your plan:

• 24-Hour Pass — full desktop access with 24 hours of cumulative usage, bound to 1 PC.
• Monthly and Annual subscriptions — recurring access with daily file limits and included credits, each bound to 1 PC.
• Shop items, DAMOS files, tokens and Tuning Credits — digital goods sold separately under their own terms.

Every license is bound to one physical computer (HWID). Moving a license to a different or new PC is a one-time €50 HWID-change fee; reinstalling the app on the same machine is free, but formatting the PC or reinstalling Windows / the operating system changes the HWID and counts as a €50 PC change. The software does not run over Remote Desktop (RDP) or virtual sessions. Legacy perpetual "Lifetime" desktop licenses (the discontinued €299 / €499 1.0.39.x product line) remain valid for the desktop application on the PC count they were sold with, but are a separate product from Cloud Edition (1.0.44+) and do not include Cloud Edition access.

Professional / business use (B2B). You represent and warrant that you purchase and use DaVinci Deluxe · Cloud Edition solely in the course of your trade, business or profession, and not as a consumer. This is a business-to-business agreement. Consumer-protection rules, including any statutory right of withdrawal or cooling-off period, do not apply, save where such rules are mandatory and cannot lawfully be excluded in your jurisdiction. You confirm you are at least 18 years old and have authority to enter into this agreement.

3. Price & Payment

All prices are shown in Euros (€) and include applicable taxes. Payment is due immediately at checkout. All payments are processed securely by Stripe with 3D Secure (Strong Customer Authentication) requested on every transaction; we never see or store your card details. We do not accept any other payment method.

4. Delivery

Delivery is digital and immediate. On payment confirmation your account is activated and your license, download link, tokens or files are made available in your profile and by email. Because the service is delivered instantly, you expressly request immediate performance at purchase.

5. Subscriptions & Renewals

Monthly and Annual plans renew automatically until cancelled. The renewal price and date are shown at checkout and in your profile, and a reminder is sent before each renewal. You can cancel at any time from your profile to stop future renewals; cancelling stops the next charge but does not refund the current paid period. Free promotional credits, tokens or bonuses attached to a plan are perks granted per period, reset each period, and are forfeited when the subscription lapses or is cancelled.

6. Acceptable Use

You agree to use the software lawfully and as a professional operator. You may not resell, rent, share, redistribute or publish the software, your license, or the files, DAMOS or definitions we deliver; reverse-engineer, crack or circumvent license protection; create multiple accounts to bypass an HWID freeze; or abuse, threaten or blackmail our support. ECU tuning is an inherently risky activity carried out entirely under your own responsibility, on your own equipment, and it is your responsibility to ensure any modification is legal in your country and for your intended use. Breach results in suspension or a permanent ban with no refund and loss of any tokens, credits or licenses on the account.

6a. Reviews, Feedback & Non-Disparagement

We welcome honest feedback, including criticism — leaving a genuine review never affects your account, licence or support, and nothing here restricts your right to publish a truthful opinion or report a real problem. This clause targets provable bad faith only. You agree not to: (a) publish or threaten a review, rating or public statement in order to obtain a refund, credit, discount or any advantage you are not owed; (b) post reviews about a purchase, product or incident that never took place, or duplicate or multi-identity reviews for a single purchase; or (c) make knowingly false statements of fact about DaVinci Deluxe · Cloud Edition or TechLT — including falsely stating that we are not the original developer, that we committed fraud, or that our software (rather than the inherent, disclosed risk of ECU flashing or your own hardware) damaged a vehicle where you never sent us the files to investigate. Conduct under (a)–(c) is a breach of these Terms resulting in permanent termination with no refund and loss of any tokens, credits or licences, and we may submit our purchase, delivery, activation, usage and authentication records to the relevant review platform and payment provider and pursue any lawful remedy for false statements of fact.

7. Liability

The software and services are provided "as is" and "as available". To the fullest extent permitted by law we exclude all warranties and conditions, whether express, implied or statutory, including any implied warranties or conditions of merchantability, satisfactory quality, fitness for a particular purpose, title and non-infringement; we do not warrant that the software is error-free, that every specific ECU or software version is covered, or that it is compatible with all hardware. ECU tuning is an inherently risky activity carried out entirely under your own responsibility, on your own equipment; the ECU Brick Risk statement at /ecu-brick-risk.html is incorporated into and forms part of these Terms. To the fullest extent permitted by law, we are not liable — whether in contract, tort (including negligence), statute or otherwise — for any damage to an ECU, vehicle, engine or component, nor for any replacement ECU, parts, labour, towing, diagnostic time, vehicle downtime, loss of profit, business or data, nor for any indirect or consequential loss, arising from a damaged or non-starting ECU, a failed flash, an interrupted write, a non-virgin file, your flashing hardware, or misuse. The user is solely responsible for the use of the software and the modifications made to ECU files. Where a file we delivered genuinely fails, your remedy is a free re-fix via "Report a Problem", never a cash refund. To the extent any liability is not lawfully excluded, our total aggregate liability for all claims connected with the software, the services or these Terms shall not exceed the greater of (i) the amount you actually paid us for the specific product or subscription period giving rise to the claim and (ii) €500, and shall not in any event exceed the amount you paid us in the 12 months before the event giving rise to the claim. Nothing in these Terms excludes or limits any liability that cannot lawfully be excluded, including liability for death or personal injury caused by our negligence, or for fraud. If any part of this section is held unenforceable, the remainder continues in full force.

7a. Indemnity

You will defend, indemnify and hold harmless DaVinci Deluxe · Cloud Edition, TechLT, its operators, staff and suppliers from and against any third-party claim, demand, proceeding, fine, loss or cost (including reasonable legal fees) arising from or connected with: (a) any vehicle, ECU or file you work on, including any claim by the owner of a vehicle you tuned; (b) your use of the software or services; (c) your flashing hardware or an interrupted write; (d) your use of non-virgin or third-party files; or (e) your breach of these Terms or of any law (including emissions, type-approval or road-traffic law) or third-party right. You warrant that you hold the vehicle owner's authorisation for every job you perform.

8. Intellectual Property

All intellectual property rights in the software, algorithms, maps, website, branding and our distinct colored logo belong to DaVinci Deluxe · Cloud Edition / TechLT. Any unauthorized reproduction, distribution or use constitutes infringement.

9. Refunds

All sales are final. Our full, binding Refund Policy forms part of these Terms and governs every purchase — please read it before you buy. In short: no money is ever refunded; any goodwill is granted only as tokens or credits on your account.

10. Changes

Updating to version 1.0.44 (Cloud Edition) is entirely optional — you may press Skip and keep using your current version. Licenses sold from 1.0.44 onwards cover 1 PC; if you bought an earlier license with more PCs, you keep the PC count you purchased on the version you already use. We reserve the right to change pricing, plans, limits, included services and these Terms at any time; new terms apply to new purchases and renewals from their effective date, while the terms of an active subscription and existing lifetime licenses are honored as sold.

11. Governing Law

As a business-to-business agreement (section 2), these Terms are governed by French law and any dispute is subject to the exclusive jurisdiction of the competent French courts — without prejudice to any mandatory consumer-protection right that nonetheless applies to you and cannot lawfully be excluded in your country of residence, which is preserved.

12. Chargebacks & Disputes

Because our digital products are delivered instantly and payments are authenticated by 3D Secure, we contest chargebacks on delivered, authenticated purchases with our complete documentary evidence. Initiating a chargeback or payment reversal on a delivered, activated or used product, in circumstances not permitted by our Refund Policy, is a breach of these Terms, and the associated processor fee and administrative costs are recoverable from you as set out in that Policy. Nothing here limits any non-waivable statutory right you may have.

13. Sole Remedy & Contact-First

Where a file we delivered genuinely fails, your sole and exclusive remedy — to the exclusion of any refund or other remedy in contract, tort or statute, to the fullest extent permitted by law — is a free re-fix via "Report a Problem", provided you re-flash your original backup and supply the original read, the tuned file and the vehicle/ECU details. Before initiating any chargeback, payment dispute, public review used for leverage, or legal action, you must first contact [email protected] and allow us 14 days to investigate and provide that free re-fix.

14. General

Entire agreement. These Terms, the Refund and Privacy Policies and the checkout disclosures are the entire agreement between us and supersede all prior statements, chats, AI-assistant or WhatsApp answers, emails, reseller or support messages; you confirm you have not relied on any representation not set out in these documents, and no statement outside them varies them or creates any right, including any refund right. No variation binds us unless made in writing by us. Severability. If any provision is held invalid or unenforceable, it is severed to the minimum extent necessary and the remainder stays in full force. Survival. Acceptable Use, Reviews & Non-Disparagement, Liability, Indemnity, Intellectual Property, Refunds, Chargebacks & Disputes, Sole Remedy and Governing Law survive any termination, ban or expiry. No waiver. Our failure or delay in enforcing any provision, or any goodwill gesture in one case, is not a waiver of that or any other provision. Assignment. You may not assign or transfer your account or licence; we may assign these Terms to a successor or affiliate on a sale or reorganisation of the business. Language. These Terms and our policies are drafted in English; any translation is provided for convenience only and, in case of conflict, the English version prevails.

By purchasing, subscribing or activating DaVinci Deluxe · Cloud Edition you confirm you have read, understood and accepted these Terms, the Refund Policy, the Privacy Policy and the Cookie Policy.
