Your timeline never leaves this computer.

Last updated November 13, 2026

The short version. The Doomscrolling Planet extension keeps everything on your computer. It has no account, no analytics and no server that receives your data. It never keeps the text of a post and never reads what you type. Its only network request asks x.com, while your world is on screen, for the latest numbers of the posts you crowned today. This website counts visits without cookies and, only if you sign up, keeps your email address to send you news.

The extension

What it reads

On x.com (and twitter.com, which redirects there), the extension reads the data x.com already sends to your browser as you scroll, and picks out posts: each post's ID, its author's handle, account ID and follower count, its numbers (likes, replies, reposts, quotes, bookmarks and views), its form (text, image, video, poll, thread, quote, link or reply), whether it is promoted or marked sensitive, and when it was posted. It also notes which posts actually appeared on your screen, and reads the counts shown under a post when the data above is missing.

Apart from the one request to x.com described under “What it sends over the network”, it makes no requests of its own, and it never posts, likes, follows or sends messages for you.

Your world and its rules use only these numbers. The extension does not keep the text of any post.

How you use x.com (for your Scroll Report)

To show you how you spend your time on X, the extension measures, inside your x.com tab:

Time: the seconds the x.com tab was in front of you and you were using it (you scrolled, clicked, moved the pointer or pressed a key in the last minute, or a video was playing). It notes that you pressed a key, never which key.
Where: the kind of page you were on (home feed, For you or Following, a post, a profile, search, notifications, messages, writing a post, or other), worked out from the page address. The address itself, what you searched for and who you messaged are not kept.
How you scrolled: the distance, and for each post the game counted, whether it stayed on screen under 2 seconds, 2 to 8 seconds, or longer.
What you did: how many times you liked, reposted, posted or replied, and bookmarked, counted from the names of x.com's own requests. Never what you wrote or which post it was.

These are times and counts only. They stay on your computer, like everything else the extension keeps.

What it stores, and for how long

Everything below is stored by the extension inside your Chrome profile, on your computer:

Posts (IndexedDB): the post details above. Deleted after 48 hours, unless you crowned that post.
Your worlds (IndexedDB): each day's world and its events, your champions (the posts you crowned, with their handles and numbers), and a summary of each finished day (its totals for the Scroll Report and how the day ended). A day's event log is kept 14 days; its totals are kept so the Report can compare weeks and months.
How you use x.com (IndexedDB): the minute-by-minute record described above, kept 14 days. Each day's totals (time on X, opens, where your time went, and so on) are kept with that day's Report.
Settings (chrome.storage.local): your choices, such as view, sound and theme.

Removing the extension from Chrome deletes all of it.

What it sends over the network

One thing. All three themes are built into the extension, so it downloads nothing. While your world is on screen, at most once every 5 minutes, it asks x.com from your open x.com tab for the current numbers of the posts you crowned today, the same request x.com's own page makes when you open a post. That request goes only to x.com, with your own login, and its answer stays on your computer. There are no analytics, crash reports, ads or accounts in the extension. Chrome itself checks the Chrome Web Store for extension updates, under Google's privacy policy.

Permissions, and why it needs them

Storage and unlimited storage: keep your worlds and settings on your computer.
Side panel: show your world in Chrome's side panel.
Alarms: close the day at your local midnight.
Access to x.com and twitter.com: read posts' numbers, measure how you use x.com for your Scroll Report, and show your world in the right column.

The website

Hosting. Vercel hosts this site. Like any web server, it processes your IP address and browser details to deliver pages, and keeps short-lived logs for security.
Analytics. Cloudflare Web Analytics counts page views without cookies and without building a profile of you. It tells us things like “120 visits today, mostly from x.com”.
Email. If you sign up, your email address is stored with Kit, our email service, and used only for Doomscrolling Planet news, such as a new theme or feature. Every email has an unsubscribe link, and we'll delete your address on request.
No ads, no tracking pixels, and we never sell or share data.

Children

Doomscrolling Planet is not directed at children under 13, and x.com itself requires its users to be at least 13.

Your choices

In Settings, export your data as a file (your worlds, Reports and usage record), or wipe all of it.
Remove the extension to delete everything it stored.
Unsubscribe from any email, or ask us to delete your address.
Questions or requests: @chungnguyen_dev on x.com.

Changes

If this policy changes, we'll update this page and the date at the top. If the extension ever starts sending anything new (for example, optional online features), it will ask you first.
