Pro privacy policy.

This page completes the DGU Chat Cleaner privacy policy for the Pro trial, the license key and the purchase; use of Pro is governed by the Pro terms. Publisher: DGU Consulting. Contact: contact@dgu-consulting.fr.

In short

The Pro trial

The trial starts only when you ask for it, in the panel or on the account page. The extension then saves on your device the dates used to count its 30 days. The trial asks for no account or email address and sends no data. Uninstalling erases it.

The license key

After purchase, Polar shows the key on the confirmation page and in its customer portal. You enter it on the extension’s account page; it is no longer shown there after activation.

To activate Pro on this browser, the extension sends Polar the key and, for a new activation, a browser label, for example “Google Chrome on macOS”. This label lets you recognise the installation in the customer portal; it contains no device identifier. Polar answers with an activation identifier.

Then, as long as a key is saved, the extension has Polar check it regularly with that identifier, including when the browser starts; the “Check now” button on the account page runs an immediate check. If Polar cannot be reached, Pro stays active for 7 days after the latest successful check, then pauses until the next one. Until a key is entered, the extension does not contact Polar.

The key, the activation identifier and the dates of the checks and of the latest Pro action are saved on your device, without sync. The extension sends Polar no data about you other than the key, the activation identifier and the label. Polar’s answers also contain the buyer’s customer record (name, email address, billing address, tax number if any): the extension only uses what is needed to validate the key and keeps none of it. Like any server, Polar’s receives the IP address and technical connection data, such as the browser, system and language.

Changing browser or removing the key

“Sign out of this browser”, on the account page, asks Polar to remove the activation, then erases the key from the device. If signing out fails or the key is refused, “Forget this key” erases it from the device without contacting Polar; the activation then still counts at Polar until you remove it in the customer portal. Uninstalling erases the trial and the key, without removing the activation at Polar.

Buying from Polar

Purchase happens on Polar’s website, opened from the account page. Polar Software, Inc., a company based in the United States, is the reseller of Pro (merchant of record): it collects payment, issues the receipt, collects taxes, delivers the license key and provides the customer portal. For this it processes your purchase data, including your name, email address, billing address and, through its payment provider, your card data, under its buyer terms and privacy policy.

DGU Consulting receives no card data. In its seller space at Polar and in the email that reports each sale, it sees the buyer’s name, email address and country, their billing address and tax number if provided, the order, and the license key with its activations, their browser label and dates, and its checks. It uses them only for support, refunds and tracking its sales, on the basis of performing the contract and its legal obligations. This information stays at Polar and in DGU Consulting’s mailbox; it is not added to any marketing list. It is kept as long as needed for support and refunds, then for the periods required by law or needed to defend rights in a dispute.

Roles and transfers

For activating and checking the key, which are needed to perform the license contract, Polar provides a service to DGU Consulting under its data processing addendum. For the sale, Polar describes its own processing in its policy. As Polar is based in the United States, the data it processes may be transferred there; its data processing addendum covers this transfer with the European Commission’s standard contractual clauses.

Your rights

You may request access to your data, its rectification, erasure or restriction, and object to its processing, subject to legal retention obligations, by writing to contact@dgu-consulting.fr: DGU Consulting answers for the data it sees and forwards the request to Polar for the rest. You may also contact Polar directly, as its policy explains. You may also lodge a complaint with the CNIL. Data saved on your device stays under your control: “Sign out of this browser” erases the key once the activation is removed at Polar, uninstalling erases the trial and the key.

Changes
