Refund Policy
⚠️ Customer responsibility: cancel your subscription yourself
Your DaVinci Deluxe account at davincideluxe.fr/profile includes a button labelled "Manage Subscription" that opens the official Stripe Customer Portal. From there you can:
- Cancel your subscription instantly -- one click, no admin approval, no need to contact support
- Update the payment card on file
- Download every past invoice
- See the next billing date and the current period end
This tool has been available since the moment you created your account. It is YOUR sole responsibility to use it to cancel before the renewal date if you no longer want the subscription. Subscriptions are auto-renewing by design (this is how Stripe subscriptions work everywhere).
If a renewal charge has occurred because you did not cancel via the Stripe portal, the charge is fully authorized and we do not issue refunds. Per EU Directive 2011/83/EU Article 16(m), digital content (which DaVinci Deluxe is) is explicitly excluded from the right of withdrawal once delivery begins, and you acknowledged this at checkout.
To stop future renewals: log in to your profile → Subscription tab → click Manage Subscription → click "Cancel plan" inside Stripe portal. You will retain access until the end of the current billing period; no further charges will occur.
1. Strict No-Refund Policy for Used Digital Goods
DaVinci Deluxe is a specialized, professional-grade automotive chiptuning and ECU modification software. Due to the digital nature of the software, the irrevocable generation of HWID-binded licenses, and the immediate access to proprietary algorithms and maps upon activation, all sales are strictly final and non-refundable once the software has been activated and used.
We log all software activations, ECU file processing events, and HWID (Hardware ID) bindings. If our server logs indicate that your unique HWID has been registered and that the software has been executed to process or attempt to process ECU mappings, you are explicitly disqualified from receiving a refund under any circumstances. This policy is strictly enforced to prevent software abuse, piracy, and fraudulent "use-and-refund" tactics.
2. ECU Functionality & Compatibility Variances
Modern engine control units (ECUs) are complex, and internal flash memory structures can vary significantly even among identical vehicle models depending on the software version, prior modifications, or dealership updates. DaVinci Deluxe operates via heuristic algorithms designed to map out DPF, EGR, SCR (AdBlue), and DTC structures.
While our software supports a vast array of ECUs, we do not guarantee 100% compatibility for every single file or software version in existence. If a specific file from an esoteric or highly modified ECU version cannot be successfully patched by DaVinci, this does not constitute a valid ground for a refund. It is the responsibility of the professional tuner to manually verify the hex dumps. Unsuccessful automated patches are considered normal occurrences in this specialized industry.
3. Mandatory Installation Prerequisites
DaVinci Deluxe requires a specific environment to function properly. Failure strictly adhere to these prerequisites will result in software failure, false-positive file corruption, or immediate closure. Refunds will categorically be denied if the user fails to configure their environment appropriately.
⚠️ Installation & Requirements
🛡️ 1. Disable Antivirus & Windows Defender
DaVinci Deluxe is 100% clean and safe. However, because it modifies engine mapping files securely and uses specialized cryptography, security heuristics often flag it as a false positive. You must completely disable your antivirus before extracting the ZIP file.
💡 Pro Tip: We have included a tool named "Disable Windows Defender" in the ZIP. Open it, select Option 3, then select Option 1. This will automatically and safely disable Windows Defender and SmartScreen.
🐍 2. Install Dependencies (Python & C++)
Before opening DaVinci, you must install the required dependencies included in the ZIP file. Depending on your PC architecture (32-bit or 64-bit), you must install both:
- Python (32-bit or 64-bit) included in the folder.
- C++ Redistributable (32-bit or 64-bit) included in the folder.
🚀 3. Launch DaVinci Deluxe
Once Windows Defender is disabled and the dependencies are properly installed, you can safely open DaVinci Deluxe. Right-click and run as Administrator for the best experience.
4. Exceptional Circumstances
Refunds are only considered in the extraordinary event where a user purchases a license but is entirely unable to activate the software due to a critical server-side fault on our end, provided that the user contacts our support team within 24 hours of purchase and zero ECU modifications have been logged.
6. Cloud Tuning (Online ECU Tuning) — Free Bonus Service, No Refund Grounds
The Cloud Tuning service (also called Online ECU Tuning / Cloud Vault) is an optional free bonus service offered as a courtesy on top of every paid DaVinci Deluxe license, plus pay-as-you-go single-job options. It is not part of the DaVinci Deluxe core software you purchased.
Cloud Tuning is processed on a best-effort, no-guarantee basis. We do our best to support a wide variety of ECUs and services, but coverage evolves continuously — recipes are added when proven, removed when an ECU+service combination is shown not to work, and we cannot guarantee any specific combination will be successful. Examples of normal (non-refundable) Cloud Tuning outcomes include:
- "AI cannot process this file" — Stage 1 / Stage 2 / specific delete services not available for a given ECU model or software version
- Unsupported file formats (partial OBD dumps, already-modified files, non-virgin reads, exotic encryption)
- Customer-side issues (wrong file uploaded, mismatched ECU selection, missing context)
- Pipeline maintenance windows or temporary recipe gaps
When a Cloud Tuning job cannot be processed, we automatically refund the tokens that were charged for that specific job to your account balance — so you don't lose value from your bonus credits. However, an unprocessable Cloud Tuning job never constitutes a valid ground for refunding your DaVinci Deluxe license itself. The core DaVinci Deluxe software (map editing, delete/module suite, daily-time access) is the product you purchased; Cloud Tuning is the bonus.
By using Cloud Tuning, you acknowledge that:
- It is a free-bonus / pay-as-you-go service, separate from your core license.
- Service availability and coverage may change at any time without notice.
- Failed Cloud Tuning jobs result only in token refund (where applicable), never license refund.
- No chargeback, dispute, or money-back claim may be filed against your DaVinci Deluxe license based on Cloud Tuning outcomes.
7. Agreement to Terms
By purchasing, subscribing, or activating a DaVinci Deluxe license, you confirm that you have read, understood, and unequivocally agreed to this Refund Policy and the ECU Compatibility & Feature Activation Policy. You acknowledge that you forfeit your right to dispute the charge via your bank or payment provider once the digital service has been rendered and logged.
