Privacy policy.

Publisher and controller for support requests: DGU Consulting. Contact: contact@dgu-consulting.fr.

In short

• No account, no publisher server, no advertising or audience measurement, no data sold.
• Your conversations are processed in your tab and only sent to ChatGPT.
• Your preferences stay on your device, without sync.
• Pro has its own privacy policy.

What the extension does

DGU Chat Cleaner lets you select conversations loaded in the ChatGPT sidebar and delete or archive them in batches, after confirmation. It is an independent tool, not affiliated with OpenAI. Pro features are added through a free 30-day trial or a license key bought from Polar.

Data used in the tab

The extension uses the titles, identifiers and links of loaded conversations, and the text of ChatGPT menus, confirmations and error messages, to present the batch, act on the right conversations and show the result. For date preselection, it reads the last activity date of these conversations from the data ChatGPT already loads, and notices that a conversation has changed without reading what was written. The selection, the summary and these dates stay in memory in the tab.

To delete or archive, the extension uses your ChatGPT session token, read in the page. ChatGPT’s answer also contains account information, including your name and email address: the extension does not use or keep it. The token stays in memory in the tab during the review and the processing of the batch; it is never saved or sent anywhere other than ChatGPT.

The extension does not retrieve the content of your messages and does not read your passwords, cookies or browsing history.

What is sent

The extension sends no data to DGU Consulting. It sends ChatGPT, within your session, one delete or archive request per conversation, after checking its access by reading your session and your conversation list. If this direct access is not available, it tells you and uses ChatGPT’s menus instead. ChatGPT handles these requests under its own terms and privacy policy.

If you enter a Pro key, the extension sends it to Polar, as described in the Pro policy. No payment goes through the extension: purchase happens on Polar’s website.

What is saved on your device

• Your language choice.
• The conversations you choose to ignore, by identifier only.
• The current batch, so that it can be resumed after an interruption: the requested action, its date, the identifier, title and result of each conversation and, if any, the resume time requested by ChatGPT. It is erased when nothing is left to resume, when you drop it or, after seven days, on your next visit to ChatGPT.
• If you use Pro, the trial and the license key, as described in the Pro policy.

This data is not synchronised and is not sent to DGU Consulting. It belongs to the Chrome profile, is shared with its incognito windows if you allow the extension there, and is not separated by ChatGPT account. You can change the language and remove exclusions in the panel. Uninstalling erases all of this data.

Your control

You choose the conversations and confirm each batch before any action. You can ask to stop after the current conversation; an interrupted batch can be resumed, without confirming again, or dropped. A completed deletion is permanent: stopping, dropping or uninstalling does not undo it.

You can close the panel, or disable or uninstall the extension in Chrome settings.

If you contact support

The support link opens your email app with the recipient and the subject “[DGU Chat Cleaner] Assistance” or “[DGU Chat Cleaner] Support”, depending on the language chosen. It does not prefill conversations or diagnostics and sends nothing automatically.

If you send an email, DGU Consulting processes your address, message content and any attachments to answer your request and resolve the reported issue. This processing is based on its legitimate interest in providing product support. Correspondence is accessible to those responsible for support and to email providers needed for delivery and storage.

Data is retained while handling the request, then only for the period needed to follow up on the issue or defend rights in a dispute, subject to applicable legal obligations. Do not send private conversations, passwords or authentication tokens.

You may request access, rectification, erasure or restriction of processing of your support data, and object to processing under the conditions set out by applicable regulations, by writing to the address above. You may also lodge a complaint with the CNIL.

This presentation website

The DGU Chat Cleaner presentation pages contain no forms, advertising, audience measurement or tracking scripts. They are hosted by Cloudflare, Inc., which processes technical connection data, such as the IP address and browser, to serve the pages and keep them secure; DGU Consulting enables no audience measurement there. This data may be transferred to the United States: Cloudflare relies on its certification under the EU-U.S. Data Privacy Framework and, failing that, on standard contractual clauses. Cloudflare sets how long it keeps this data according to the criteria of Cloudflare’s privacy policy. This processing is separate from that of the extension.

Other pages on dgu-consulting.fr are covered by the website privacy policy.

Changes

This policy describes version 0.6.0. The Pro trial, the license key and the purchase from Polar are described in the Pro privacy policy. Any change to the data used will be published here with the version concerned.
