Theme Studio
Privacy policy
Last updated 17 September 2026
The short version: Theme Studio for LeetCode collects nothing and sends nothing anywhere. Everything it stores stays in your own browser.
1.Who this covers
This policy covers the Theme Studio for LeetCode browser extension, built and maintained by Vinay Tiwari (vinaytz). It explains what the extension stores, where that goes, and what it never does.
2.What it stores
In your browser's local extension storage (chrome.storage.local):
- The theme you picked.
- Your Anime Studio settings: scene, glass, visibility, and the moments, sound and volume switches.
- If you add your own picture in Anime Studio, a resized copy of that picture and a small blurred copy of it.
- Whether focus mode is on.
3.Who else sees it
No one. None of it leaves your device, and it is never sold, shared or sent to me or to any third party.
4.What it does not do
- It does not collect, transmit, sell or share any personal or usage data.
- It makes no network requests. Fonts, images and sound effects are bundled with the extension or generated on your device.
- It uses no analytics, tracking, advertising or accounts.
- It does not read your code, your submissions or your LeetCode account information. It only restyles the page and notices when a Run or Submit result appears, so it can play the optional effect.
5.Where it runs
Only on LeetCode problem pages (leetcode.com/problems/* and leetcode.cn/problems/*), and on its own settings page, Anime Studio.
6.Your choices
- Everything the extension stores is removed when you uninstall it.
- You can remove your own picture at any time from Anime Studio.
7.Children
The extension is not aimed at children, and I don't knowingly collect information from them.
8.Changes
If this policy changes, the updated version will appear on this page with a new date at the top.
