Effective July 2, 2026
This policy covers the website at tabshighscore.com (and tabhighscore.com, which redirects to it) and the Tabs High Score Counter Chrome extension. The whole project does one thing: it lets you post how many browser tabs you have open to a public leaderboard.
The extension’s single purpose is to measure the number of open tabs so the website can post a verified score. It is built to know as little as possible:
tabs permission, Chrome strips URLs and titles
from its tab query — the extension can only ever learn the
number of open tabs, never what is in them.externally_connectable) permits only tabshighscore.com
pages to send it a message; it runs no code on, and cannot read or
modify, any web page.The tab count is the only piece of information about your browser use the extension touches. It exists solely to power the user-facing leaderboard feature described on the store listing and on the site, and it is used for nothing else.
When you click Submit score — and only then — the site sends and stores:
tabid cookie value and a timestamp
(see below). Not shown publicly.Reading the leaderboard sends nothing beyond an ordinary web request. We do not store IP addresses or user agents in our database. Cloudflare, which hosts the site, processes standard request metadata to deliver and secure it, as any host does.
The site sets one first-party cookie, tabid: a random
identifier generated in your browser, kept for up to one year. It has two
jobs: the leaderboard counts each browser once per time window (your best
score, so one person can’t fill the board), and submissions without it
are rejected (basic spam reduction). It is not used to track you, on this site
or anywhere else. There are no third-party cookies.
Data is used solely to operate the leaderboard: displaying top scores, deduplicating entries per browser, and preventing abuse. It is shared with no one, except:
We do not sell user data. We do not use it for advertising of any kind. We do not share it with data brokers, advertising platforms, or information resellers, and we do not use it to assess credit-worthiness or for lending purposes.
The use of information received from Chrome APIs by Tabs High Score Counter adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Concretely: the only such information is the tab count, its use is limited to providing the leaderboard feature, it is transferred to no third party (other than our hosting provider as described above), and no human reads it except as aggregated public leaderboard entries or as needed to investigate abuse or comply with law.
The site is served exclusively over HTTPS, and all data travels encrypted in transit. Scores are stored in Cloudflare’s D1 database, which is not publicly accessible. The project handles no passwords, no payment or financial information, and no health information.
Scores are kept indefinitely — that is what an all-time leaderboard is. If you want an entry removed (for example, you used your real name and regret it), open an issue on the project repository naming the entry and roughly when it was posted, and we will delete it.
The site is not directed at children under 13, and we do not knowingly collect any personal information beyond a self-chosen display name and a tab count from anyone.
If our data practices change, we will update this page and its effective date. If the extension’s data practices ever change, the change will also be prominently disclosed in the extension’s store listing before it takes effect.
