X Cleaner Chrome Extension
Operated by d2fl
Effective date: June 21, 2026
Last updated: July 8, 2026

This Privacy Policy describes how the X Cleaner browser extension (“Extension,” “we,” “us”) handles information when you install and use it. The Extension helps logged-in X (x.com) users collect, filter, and export their following or followers lists.

Summary: The Extension stores your lists, filters, and settings locally in your browser. It interacts with X (x.com / api.x.com) only while you use it. We do not sell your data, run advertising trackers, or operate a separate analytics service for this Extension. Fast mode uses more X API calls and faster scrolling (higher rate-limit risk); Gentle mode is slower, page-native pacing for lower profile or overnight use.

1. Information we process

Depending on how you use the Extension, the following information may be processed:

Your X account handle — detected from an open, logged-in X tab.
List data — usernames and profile details (counts, bio, created date, etc.) from collection (following or followers) or CSV you load.
Enrichment data — computed locally: last-post timestamps, mutual flags (you_follow / follows_you), bot signals, verified status, inactive status (Following only).
Activity / status logs — local timestamps and results of collections and filters.
Extension settings — Fast vs Gentle collection mode, fresh-start per branch, filter options (mutuals, verified, inactive, bots), delays.
Usage limits — local free-tier counters (up to 200 handles per 24 hours for collect, import, and export).
Subscription status — Pro eligibility cached locally (X @d2fl subscription check or built-in owner accounts).
X session data — cookies/session used only in your browser to call X APIs and verify subscription status; not sent to d2fl servers.

2. Where data is stored

• chrome.storage.local — per-branch lists (following/followers), settings, activity cache, enrich archive, subscription cache.
• chrome.storage.session — short-lived flags (cleared on browser session end).

We do not operate a central server database for your lists or logs. All data stays on your device.

3. How we use information

Collect lists in Fast (bulk REST/GraphQL + faster scroll) or Gentle (slower page-native pacing; may use limited API recovery) mode.
Cross-populate mutual flags and related data when collecting one branch if the user appears in the other — and the same for CSV loads.
Run filters (mutuals, verified, inactive/last-post for Following only, bots for Followers only).
Support fresh start per branch only (other branch untouched).
Save progress locally for resume; enforce free-tier limits.
Determine Pro status for unlimited collect, import, and export.
Display progress in popup and on-page HUD.
Download CSV files you export via the browser downloads API.

4. Network activity and third parties

The Extension communicates with X (x.com and api.x.com) only. It does not upload your lists, mutual flags, last-post data, logs, or personal data to d2fl during normal operation.

Clicking Subscribe @d2fl for unlimited opens X’s website; X’s policies apply. We are not affiliated with X Corp.

Fast mode performs more aggressive X API calls and faster scrolling (higher chance of temporary rate limits or reduced reach). Gentle mode prefers slower page-native signals and may still use limited API recovery for shortfalls.

5. Permissions

Permission	Purpose
storage	Save per-branch lists, settings, caches, logs locally
tabs	Open/focus X tab and handoff to HUD

x.com / api.x.com	Required for collection, enrichment, and subscription checks

6. Data sharing and sale

We do not sell or share your data for marketing. Data stays on your device unless you export a CSV yourself. Cross-branch mutual detection and last-post enrichment happen locally only.

7. Deletion

Clear lists or use Stop in the UI/HUD.
Fresh start checkbox for the selected branch only (other branch remains).
Uninstall the Extension from Chrome (local storage removed).
Clear browser extension data.

8. Children

Not directed to children under 13.

9. Security

Data remains on your device under Chrome’s extension model. No remote transmission of your lists or enrichments to d2fl.

10. Changes

We may update this policy; the date above will change.
