Pro terms.

These terms apply to the Pro trial and license of DGU Chat Cleaner, an extension published by DGU Consulting (see the legal notice). The free version can be used without them.

1. Seller and publisher

Pro is sold by Polar Software, Inc., reseller (merchant of record): Polar collects payment, issues the receipt, collects taxes and delivers the license key, under its buyer terms. DGU Consulting publishes the extension, provides Pro and handles support. These terms form the supplier agreement referred to by Polar’s buyer terms.

2. What Pro includes

Pro adds to the panel activity date preselection and adding conversations to the ignored list. Without Pro, cleanup stays complete: selection, bulk deletion and archiving, resuming an interrupted batch and removing exclusions.

3. Free trial

The trial gives access to Pro for 30 days, without payment, account or email address. It starts only when you ask and ends by itself: no payment follows. A batch confirmed during the trial runs to completion even if the trial ends meanwhile.

4. Price and payment

The price, including taxes, is shown on Polar’s payment page before purchase. It is paid once: no subscription and no renewal.

5. License

The purchase grants a personal, non-exclusive and non-transferable license to use Pro on two browsers at a time with the same key. To change browsers, free a place with “Sign out of this browser” on the account page, or in Polar’s customer portal. A key shared or published in breach of these terms may be revoked.

“Lifetime” means that the license does not expire and calls for no later payment. It lasts for the life of the product: Pro and its updates are provided as long as DGU Consulting publishes the extension.

6. Limits

• Pro works, like the free version, in Chrome on desktop, on chatgpt.com.
• The extension depends on the ChatGPT website, which OpenAI can change at any time; a feature may stay unavailable until the extension is updated. DGU Chat Cleaner is not affiliated with OpenAI.
• The key is checked online by Polar on a regular basis: an internet connection is needed from time to time. Without a successful check for 7 days, Pro pauses until the next successful check; free cleanup stays available.
• Deletion is permanent. You choose and confirm each batch before it starts.

7. Refunds and withdrawal

You can get a refund for Pro, without giving a reason, by asking within 14 days of purchase. This period covers the right of withdrawal provided by law.

After 14 days, a refund is granted if a Pro defect reported to support is not fixed within a reasonable time, for a duplicate purchase or if the key cannot be activated.

To ask, write to contact@dgu-consulting.fr from the purchase email address or with the order number. DGU Consulting issues the refund from its seller space at Polar within 48 hours of the request, to the payment method used, and the key is then revoked.

These commitments limit neither the legal guarantee of conformity for digital content and services under the French Consumer Code, nor any other right you have under the law.

8. Support

Support is provided by email, in French or English, at contact@dgu-consulting.fr.

9. Personal data

Trial, key and purchase data are described in the Pro privacy policy.

10. Changes to these terms

DGU Consulting may change these terms; the version in force on the purchase date applies. A change never reduces rights acquired by an earlier purchase.

11. Governing law

These terms are governed by French law, without depriving you of the protection of the mandatory rules of your country of residence. If a problem arises, write to support first to look for an amicable solution together.
