X Post Local Time Privacy Policy

X Post Local Time is a Chrome extension that shows the time of posts on x.com and twitter.com in absolute local time instead of X’s relative timestamps, and keeps a list of live local clocks for the accounts you choose to track.

Effective Date: September 12, 2026
Last Updated: September 12, 2026
Product: X Post Local Time, Chrome extension

X Post Local Time does not sell your data, does not use it for advertising or tracking, and does not send your data to developer-controlled servers.

Everything it stores stays in your browser’s local extension storage. The extension has no server, no analytics and no third-party services. The only network activity it causes is your own browser loading pages on x.com and twitter.com with the X session you are already signed into.

Information X Post Local Time Handles

When you add an account to track, the extension stores the following on your device:

The account’s public profile information: username, display name, avatar URL, and the location text the account owner published on their own public profile.
A time zone inferred from that location text, or the one you set yourself.
Your display preferences, such as whether to replace X’s relative timestamp and whether to use a 12-hour clock.

How X Post Local Time Uses This Information

To replace the relative timestamp on each post (“2h”) with your own local time.
To show the author’s local time underneath posts from accounts you track.
To show each tracked account’s current local time, weekday, date and UTC offset.
To let you correct or override an inferred time zone.

The extension does not require an account, does not ask you to sign in, and does not build a profile of you. It is not affiliated with X Corp.

All data is stored locally in your browser through the extension storage API (chrome.storage.local). The extension does not operate a backend server.

The extension does not sell, rent or share data with advertisers, data brokers or any other third party. There is no analytics, no telemetry and no crash reporting, and the extension loads no remote code — all of its code is contained in the installed package.

How the Extension Reads an X Profile

To learn an account’s time zone, the extension opens that account’s public profile page in a background tab, reads the location field from the page, and closes the tab again. The page is loaded by your own browser using the X session you are already signed into, exactly as if you had opened it yourself. The extension never asks for your X password and does not read your cookies or tokens itself.

Permissions

storage — to save the accounts you track and your display preferences on your device.
scripting — to read the public location field from a profile page when you add an account.
Access to x.com and twitter.com — the extension runs only on these two sites, where it rewrites post timestamps and reads profile pages. It does not request access to any other site.

Data Retention and Deletion

Tracked accounts and preferences remain in your browser until you remove them. Removing an account from the list deletes the data stored for it. Uninstalling the extension removes all of its stored data, because that data only ever existed in your browser’s extension storage.

Children’s Privacy

X Post Local Time is not directed to children and does not knowingly collect personal information from children.

International Use

X Post Local Time processes everything on your own device. No data is transferred to the developer or to any other party, so there is no cross-border transfer of your data.

Changes to This Policy

This policy may be updated when X Post Local Time changes how it handles data. The latest version will be published on this page with an updated date.
