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

• 10-day trial, 0.99 EUR: non-refundable. Unless you cancel before the trial ends, the Monthly license (79.99 EUR/month) starts automatically on the same card (section 6).
• Monthly and yearly licenses: non-refundable. Cancelling stops future renewals only; no payment already made is ever refunded, and the license stays active until the end of the paid period.
• 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; 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.

All sales are final: no refunds are offered, for any reason. This applies to every product, whether it was used or not. We do not offer compensation in kind either: no extra days, tokens, credits or codes (section 9).

●Payment security & 3D Secure

• Every new purchase is card-only and is verified by your bank with 3-D Secure (usually you approve it in your banking app; sometimes your bank verifies it automatically). Subscription renewals are charged automatically to the card you approved when you subscribed. Payments are processed by Stripe; we never see or store your card number.
• A 3-D Secure payment is authenticated by your own bank: usually you approve it in your banking app; sometimes your bank verifies it automatically. 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.No refunds: all sales are final

• 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.
• No refund is offered for any purchase, whether or not the license was activated, a Reg ID was bound or a file was processed. This rule has no exceptions.
• This includes a change of mind, a purchase that turned out not to be needed, a PC that does not meet the requirements (section 2) and a specific ECU or file with 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 have no record of it and no control over 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 0.99 EUR 10-day trial 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.
• 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.
• No payment is refunded, in full or in part: not for unused days, weeks or months of a period that has started, and not for a renewal that has been charged. It is your responsibility to cancel before the renewal date if you do not want to continue.

6.10-day trial

• The trial costs 0.99 EUR and gives access to the real software for 10 days, with up to 10 tunable files in total.
• Unless you cancel before the 10 days end, your Monthly license (79.99 EUR/month, 10 tunable files a day) starts automatically on the card you used, and then renews as described in section 5. We send a reminder before that first monthly charge. Cancel any time from your account page (Manage subscription): you keep the trial until it ends and the monthly is not charged.
• Buying a full license during the trial cancels the trial and starts the license right away.
• It can be bought once per customer. Buying it again with a different e-mail, name or card is not permitted (Terms, section 7).
• It exists so that you can check compatibility with your PC, your tools and your files before taking a license. The trial payment is never refunded.

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 never refunded, including when the license later expires or is cancelled. They require an active license to be used.
• Unused tokens are not carried over: the counter refills on a rolling 24-hour cycle.

8.ECU damage risk — my own responsibility

This is the wording you accept at checkout:

9.No compensation

• We do not offer compensation of any kind for a purchase: no money, no extra days on the license, no extra tokens, credits or codes.
• If something does not work, write to support: we help you fix the real problem (section 10).

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.
