Privacy Policy for Old Reddit Curator
Effective Date: July 30, 2026
Old Reddit Curator (formerly Old Reddit Filter Suite) is developed by DoubleDingoDevelopment.
This Privacy Policy explains how Old Reddit Curator handles information when you use the extension. The extension is a content filter for old.reddit.com. There is no developer server, no analytics, no telemetry, and no advertising. Nothing you do in the extension is reported to the developer, because there is nowhere for it to be reported to.

Summary
Old Reddit Curator does not sell your data.
Old Reddit Curator does not upload your lists, filters, browsing activity, or any other information to a server operated by DoubleDingoDevelopment.
Old Reddit Curator does not use a backend server, cloud database, online account, or remote account system.
The extension runs only on old.reddit.com and does nothing on any other website.
What the extension stores on your device
All of the following is created by you and lives in your browser's extension storage:
Subreddit lists - the subreddits you marked Approved or Blocked.
Word filters - the words and phrases you typed, in Exact and Aggressive form.
Blocked users - the Reddit usernames you chose to block.
Karma block profiles - the named threshold rules you built, and their on/off state.
Hidden posts - IDs of posts you swept or hid, in timestamped batches, so you can unhide them later. The newest 2,000 travel with sync; older entries move to an unlimited archive on your device and are never deleted to save space.
Undo history - the last 25 actions per list, so the undo buttons work.
Author karma cache - see section 4.
Settings - sort order, list toggles, hiding style, and which sync backend you selected.
What the extension reads from web pages
The extension runs only on old.reddit.com. On those pages it reads the post listings already displayed to you - post titles, subreddit names, and author usernames - in order to decide which posts to hide. Post titles are matched against your word filters and then discarded; they are never stored and never transmitted.
The extension does not run on any other website, cannot see any other tab, and does nothing on www.reddit.com.
Network requests
The extension makes four kinds of request. None of them goes to the developer.
Public Reddit profile data (only if you use Karma Block Profiles). The extension requests old.reddit.com/user/<username>/about.json for authors whose posts appear in your feed, reading only the public link karma, comment karma, and account creation date - the same information any visitor sees on a Reddit profile page. Requests are rate-limited to roughly one account every 350 ms and the result is cached locally for seven days. If you never create a Karma Block Profile, these requests never happen.
The next page of the listing you are already reading (endless scrolling). Identical to the request your browser would make if you clicked "next" yourself.
Reddit-hosted images in comments (only if you switch on "Show images posted in comments"). Image links in comments are shown as the images themselves, loaded from Reddit's own image servers (i.redd.it / preview.redd.it) exactly as if the comment displayed them natively. Off by default.
Google Drive - only if you explicitly connect it. See section 5.
Syncing between your own devices
You choose one of two backends, or neither. In both cases the data is your own filter lists, and in both cases it goes to your account - never to the developer, who has no ability to read it.
Chrome sync (default). Your lists are packed, compressed, and stored through chrome.storage.sync. Chrome moves them between the Chrome profiles you are signed into. This is Google's own sync mechanism, governed by Google's privacy policy.
Google Drive (optional, off until you turn it on). If you press "Connect Google Drive", the extension opens Google's own account chooser and requests an access token limited to the single scope drive.appdata. That scope can reach only a hidden application-data folder belonging to this extension - it cannot see, read, or modify any other file in your Drive, and the extension is never given your name, email address, or profile.
The extension writes one file, sbxsync.json, containing the same lists described above, and reads it back to merge changes made on your other devices. The file does not appear in your Drive listing. A five-minute alarm checks for changes made elsewhere.
The access token is short-lived (about an hour), is held in memory rather than written to disk, carries no refresh token, and is sent only to Google's own endpoints. Switching the backend back to Chrome sync revokes it.
Import and export
Export writes a plain JSON file to your computer through your browser's normal download. Import reads a file you select. Neither involves any server.
What is never collected
No browsing history, and no record of the pages you visit. No personal information: no name, email address, phone number, postal address, date of birth, or government identifier. No location data. No keystrokes, clicks, mouse movement, scrolling, or any other behavioural telemetry. No message, comment, or post content that you write. No payment or financial information. No health information. Nothing at all is transmitted to the developer.
Who receives your data
Nobody but you. Your data is not sold, rented, traded, or transferred to any third party. It is not used to build a profile of you, to target advertising, to assess creditworthiness, or for any purpose other than filtering your Reddit feed the way you told it to.
Deleting your data
Individual entries - remove them from any list in the extension's menu, or use the per-list undo.
Everything at once - remove the extension at chrome://extensions. Chrome deletes its local and synced storage.
The Drive copy - switch the backend back to Chrome sync in the Cross-Device Sync panel, then remove the extension's app data from your Google account at myaccount.google.com/permissions.
Changes to this policy
If this policy changes, the updated version will be published at this URL and the date at the top will change. Material changes will also be noted in the extension's changelog.
