Privacy Policy

How the X Bookmarks Archive extension and this website handle your data

This policy covers the Chrome extension "X Bookmarks Archive" and the website shelf.zimolab.org. In short: your bookmarks and likes stay on your own computer. We never see them.

Extension: data stays on your computer

  • Using the session you are already signed in with on x.com, the extension calls X's own web interfaces to read your bookmarks and likes (post text, authors, image and video links, dates) and stores them locally in your browser (IndexedDB).
  • It never likes, bookmarks or posts on your behalf. The only action that changes data on X is when you manually click "Remove on X" on a single post and confirm: it affects that one post only, just like clicking it on X, and there is no bulk option.
  • The cookies permission is used only to read the twid cookie on x.com, to tell which X account is signed in so data can be kept per account. Credentials are used only inside x.com pages and are never stored, exported or sent to us.
  • To complete post details, the extension may request public post data from X's own service (cdn.syndication.twimg.com).
  • This data is never uploaded to our servers. You can clear it in the extension's settings; uninstalling the extension also removes it.

Extension: AI organize (Pro, optional)

  • Used only after you enter your own API key, agree to send content and start organizing.
  • The extension sends short digests of the posts being classified (post text, author handle, link domains, quoted snippets) and your tag names directly from your browser to the AI service you chose (DeepSeek or Anthropic), not through our servers. That service's privacy policy applies to this data.
  • Your API key is stored only in your browser.

Extension: Pro activation

Activating Pro, and re-verifying about every 7 days, sends to shelf.zimolab.org:

  • the activation code;
  • a randomly generated device id (contains no personal information);
  • the device type, such as "Mac · Chrome".

The server keeps these and the last verification time only to count the slots used by each code (up to 3). No bookmarks, likes or X account data are sent.

Website: purchases

  • When you buy Pro we record the order number, amount, payment status and the payment provider's transaction number, to deliver and recover your activation code.
  • Payments are handled by Z-Pay and WeChat Pay. We never receive your WeChat account or card details.
  • The purchase page remembers your latest order in your browser (localStorage) so you can come back to your code.
  • This website uses no ads and no third-party analytics. It is hosted on Cloudflare, which keeps standard access logs (such as IP address and time) for security and troubleshooting.

What we never do

  • Sell or rent any of your data;
  • Use it for advertising or profiling;
  • Use it to determine creditworthiness or for lending.

The extension's use of data complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.

Deleting data

  • Extension data: use "Clear local data" in settings, or uninstall the extension.
  • Activation records: "Remove code" in the extension deletes that device's record; you can also email us to delete all records of your order (you will then be unable to recover the code).
