Privacy & Disclosures

Your text never leaves your browser

ClearPen analyzes your writing entirely on your own device, using JavaScript that runs in your browser. The text you paste is never uploaded, transmitted, or stored on any server. There is no account, no login, and no database. When you close the tab, the analysis is gone.

What is stored on your device

For convenience, the most recent text you entered is saved in your browser's local storage — a small store that lives only on your computer or phone — so your work is still there if you return. It is never sent anywhere and you can clear it any time with the "Clear" button or by clearing your browser data.

Analytics

If analytics is enabled, this site uses Cloudflare Web Analytics, which is privacy-first and cookieless: it measures page views and general traffic without fingerprinting you, without cookies, and without collecting personal data. It never has access to the text you analyze. If analytics is not enabled, the site makes no third-party requests at all.

Affiliate disclosure

ClearPen is free. To cover its costs it may include affiliate links to writing tools such as ProWritingAid or Grammarly. If you start a paid plan through one of these links, ClearPen may earn a commission, at no extra cost to you. These are options we list, not endorsements; we are not affiliated with these companies. Always compare features and pricing yourself. This disclosure is provided in line with the U.S. Federal Trade Commission's guidance on endorsements (16 CFR Part 255).

Cookies

ClearPen sets no advertising or tracking cookies. The only data kept on your device is the local-storage copy of your last text, described above.

Disclaimer

Readability scores and style flags are well-known heuristics, not rules or professional editing. They are provided "as is", for general guidance. Good writing sometimes scores poorly on purpose. ClearPen makes no warranty that following its suggestions will achieve any particular result.

Questions about this page can be sent to the address listed in the site's affiliate or contact details once published.
