Refund & ECU Policy

This policy is part of the Terms & Conditions of DaVinci Ghost and is accepted at checkout. It explains why sales of this digital product are final, how payments are secured and what happens with ECU compatibility, PC binding and chargebacks.

●At a glance: all sales are final

• Test pass, 9.99 EUR: non-refundable once the account is activated or the hour has started (first login in the app).
• Monthly and yearly licenses: non-refundable. Cancelling stops future renewals only; the current paid period is never refunded and stays active until its end.
• Daily token level upgrades, 199.99 EUR (20 tokens/day), 299.99 EUR (30), 399.99 EUR (40) and 499.99 EUR (50): non-refundable once applied to the account; they stay active only while the license is renewed without interruption and are forfeited when the license lapses.
• PC move, 99.99 EUR: non-refundable once the new PC is bound.

We never refund money. Any goodwill, when we decide to grant it, is given only as extra days or extra tokens on the account (see section 9).

●Payment security & 3D Secure

• Every payment is processed by Stripe, with 3D Secure requested from your bank. We never see or store your card number.
• A 3D Secure payment is authenticated by your own bank, with your own device or banking app. A dispute claiming that a payment was "unauthorized" is contradicted by the bank's own authentication record.
• For every account we retain the IP address and timestamp of the purchase, the acceptance of these policies at checkout, the activation of the account, the bound Reg ID and the usage logs (logins and processed files). This evidence is submitted to the bank and to Stripe automatically to contest any chargeback.
• Opening a chargeback against a delivered digital product is a breach of these terms and results in the permanent suspension of the account and of the bound PC (section 2.2).

●Your card statement shows TECHLT

DaVinci Ghost is a brand operated by TechLT (techlt.net). The charge appears as TECHLT on your bank or card statement. Please check this before reporting a charge you do not recognise: a "TECHLT" line dated the day of your purchase is your DaVinci Ghost payment.

1.Strict no-refund policy for used digital goods

• The software, the license attached to your account, the daily tokens and the PC move are digital goods and services delivered online, with no physical product and nothing that can be returned.
• We log the activation of every account, the binding of the Reg ID and every ECU file processed by the analysis engine, with date and time.
• A bound Reg ID or any processed file disqualifies a refund request. This policy is enforced without exception against "use and refund" tactics: buying a license, processing files and then asking for the money back.
• Refunds are never granted for a change of mind, for a purchase that was not needed after the product had been used, for a PC that does not meet the requirements (section 2), or because a specific ECU or file has no solution available (section 3).

1.1No affiliation with aesoftech.com or any other product called "DaVinci"

• DaVinci Ghost is an independent product, sold only at davinci-ghost.com, with its own interface, its own logo and its own Stripe checkout. It has no connection with aesoftech.com or with any other software, website or company using the name "DaVinci".
• A payment made to another company, on another website or for another product is that company's responsibility. We cannot see, refund or transfer it.
• Brand confusion between products is never a ground for a refund of a DaVinci Ghost purchase. If you are not sure what you bought, check the "TECHLT" line on your statement and the confirmation e-mail from Stripe.

2.Installation & requirements

• Windows 10 or Windows 11, 64-bit, with .NET Framework 4.8. The software does not run on macOS, Linux, Android or in a browser.
• The software is a single .exe installer. Run it as administrator (right-click › Run as administrator). If Windows SmartScreen shows a warning, click "More info" and then "Run anyway".
• A permanent internet connection is required: files are analysed on our servers and the license is checked at each login.
• Remote desktop (RDP), virtual machines and other virtual sessions are not supported: the Reg ID of such sessions is unstable and they are used to bypass the one-PC rule. Install the software on a physical Windows PC.
• You are responsible for checking these requirements before purchasing. The 9.99 EUR test pass exists so that you can try the real software on your own PC, tools and files first.

2.2Chargebacks

• If something is wrong with a charge, write to [email protected] first. Genuine billing errors, such as a duplicate charge, are corrected quickly.
• When a chargeback or dispute is opened with the bank instead, the account and the bound PC are permanently suspended the moment the dispute is received: every license, token level and PC binding attached to the account stops working.
• The usage evidence described above (3D Secure authentication, IP and timestamps, policy acceptance, activation, Reg ID, logins and processed files) is submitted to the bank and to Stripe automatically.
• The account stays closed even if the dispute is later withdrawn or lost by the customer, unless the customer contacts support and the situation is resolved. Whatever the outcome, we do not open a new account for a customer who has filed a chargeback.

3.ECU functionality variances

• There are thousands of ECU types and software versions, and they differ by manufacturer, model, software number and even production batch. DaVinci Ghost identifies the ECU of the exact file you opened and shows which of its solutions apply to it.
• A specific file without a solution, a solution that is not available for a specific software version, or an unsuccessful patch is a normal, disclosed variance of ECU tuning and is never a ground for a refund.
• A token is charged only when the analysis confirms that the file is tunable. If the analysis fails or the ECU has no solution available, nothing is charged and the file is logged as "not tunable".
• The list of supported ECUs is indicative and updated automatically from the analysis engine; it is not a guarantee that a specific solution exists for a specific file.

4.License binding: one account = one PC

• One account works on one PC. The first login in the app binds the account permanently to the Reg ID (hardware identifier) of that PC. Do it on the PC you will work on.
• Reinstalling the software on the same PC is free: the Reg ID does not change.
• Formatting the PC, reinstalling Windows or changing major hardware changes the Reg ID and counts as a PC move (99.99 EUR), exactly like moving to a different PC. Back up nothing else: the license lives in your account, not in a file.
• A PC move is paid by card either from the app (log in from the new PC and choose "Move license to this PC") or from the account page by entering the new PC's Reg ID. The old PC stops working the moment the payment clears. The move is non-refundable once the new PC is bound.
• In exceptional and documented cases (for example a PC that is stolen or destroyed) the owner may reset the binding, at his sole discretion and without any obligation to do so. Write to support from the e-mail of your account.

5.Subscriptions & renewals

• Monthly and yearly licenses renew automatically at the end of each period, at the price shown at checkout, until you cancel.
• A reminder is sent by e-mail 3 days before each renewal, with the date, the amount and how to cancel.
• You can cancel at any time from your account page (Manage subscription / invoices) or from the app (Info › Upgrade Tokens › Manage subscription). Access continues until the end of the period already paid.
• There are no partial refunds for unused days, weeks or months of a period that has started, and a renewal is not refunded once charged. It is your responsibility to cancel before the renewal date if you do not want to continue.

6.Test pass

• The test pass costs 9.99 EUR and gives access to the real software for one hour, counted from the first login in the app, with 3 tokens during that hour.
• It can be bought once per customer. Buying it again with a different e-mail, name or card is not permitted and such purchases are cancelled.
• It is non-refundable. It exists precisely so that you can check compatibility with your PC, your tools and your files before taking a license.

7.Token levels

• Every license includes 10 tokens a day. The 20 tokens/day (199.99 EUR), 30 (299.99 EUR), 40 (399.99 EUR) and 50 tokens/day (499.99 EUR, the maximum) upgrades are one-time payments that raise the daily level of the account they were bought for.
• They apply to that account only, are not transferable to another account or person, cannot be split, and are not refunded if the license later expires or is cancelled. They require an active license to be used.
• Unused tokens are not carried over: the counter resets every day at midnight, Europe/Madrid time.

8.ECU damage risk — my own responsibility

This is the wording you accept at checkout:

9.Goodwill

• When we decide to help a customer beyond these terms (for example after a genuine technical problem on our side), goodwill is granted only as extra days on the license or extra tokens on the account.
• Goodwill is never paid as money, never refunded to a card and never owed: it is a gesture, decided case by case, and it does not create a right to the same gesture in the future.

10.Contact support first

• Support: [email protected]. Write from the e-mail of your account and include your Reg ID (shown in the login window of the app and on your account page). If it is about a file, add the ECU shown by the analysis.
• Questions about a token charge are reviewed against the file log of your account, which you can also see on your account page.
• Talking to support before doing anything else is the fastest way to solve a problem, and the only way to keep your account if there is a payment issue.
