Privacy Policy for d2jsp Enhancer

Last updated: July 2026

This Privacy Policy explains how the "d2jsp Enhancer" Chrome extension ("the Extension") handles information.

1. Information We Collect

The Extension stores only data you create through your own use of it, or that it reads from your own d2jsp.org account activity in order to power its features:

- Usernames you choose to block or favourite, along with any tags or notes you add to them

- Posts you choose to save

- Your extension settings and preferences

- Fast-reply prefill button labels you define

- A PM subject and body template you save

- Your gold trade transaction history (date, amount, balance, counterpart, comment) — read from your own gold.php history so it can be shown back to you as a dashboard

- Your private message history (sender, recipient, subject, message body) — mirrored locally so it can be shown in the Messenger-style panel

- Which topics you've read on subforums you've chosen to track, so the Extension can flag new activity

- Trade-listing inventories you build in Smart Shop, and the item database backing it

- Notes you write in the Notes scratchpad

- Screenshots you paste or drop into the OCR item scanner — these are processed entirely on your device using a bundled OCR library; the image itself is never stored or uploaded anywhere, only the text extracted from it is kept

All of the above is stored locally on your device using the browser's chrome.storage.local (and, for some Smart Shop data, localStorage) APIs.

We do not collect your name, email address, IP address, general browsing history, or any data unrelated to your use of d2jsp.org through this Extension.

2. How We Use the Information

Locally stored data is used solely to power the Extension's features while you browse d2jsp.org — hiding blocked users, highlighting favourites, loading your saved templates, displaying your gold trade history and message history back to you, and flagging forum activity. No data is used for any other purpose, and none of it is used for advertising, analytics, or profiling.

3. Network Requests

The Extension only ever makes requests to d2jsp.org — never to any other domain. Most requests happen when you directly trigger an action (hovering over a topic title, clicking Send, clicking a sync button). Some also happen automatically as part of normal use of a feature you've enabled — for example, checking for a new-message banner on page load, or a background tab briefly refreshing your gold trade history while you use the Gold Tracker's history backfill. These automatic requests are always limited to d2jsp.org and only run for features you're actively using; they never contact any server other than d2jsp.org, and no data collected from them ever leaves your device.

4. Data Sharing and Transmission

We do not transmit, share, or sell any data to third parties or external servers. All data remains on your local device at all times.

5. Data Storage and Security

Your data is saved locally in your browser and is only accessible by this Extension. You can delete it at any time by:

- Using the individual "Clear" buttons available for each feature in the popup (blocked users, favourites, saved posts, forum activity tracking, and more),

- Using the Export / Import tools to manage your data manually,

- Or uninstalling the Extension, which removes all locally stored data.

6. Changes to This Policy

We may update this Privacy Policy occasionally as the Extension's features change. The "Last updated" date will be changed accordingly. Continued use of the Extension after changes constitutes acceptance of the new policy.
