FIFTEEN
Back to the copy test

Effective August 18, 2026

Privacy, in plain English.

FIFTEEN is built to analyze B2B website copy without turning your work into somebody else's dataset.

What the tool processes

How it is used

The clarity score runs in your browser. Submitted copy passes through our Cloudflare Worker and is sent to OpenAI to generate detailed copy and CRO recommendations. If that service is unavailable, Cloudflare Workers AI may generate the report instead. We do not save submitted copy unless you sign in and explicitly save the audit. If you share report feedback, we store the generated report, page URL and your optional note. The source copy is not stored through the feedback form.

Accounts and saved audits

Accounts are optional. Account and saved-audit data is stored in Cloudflare D1. Passwords are stored as salted hashes, not readable passwords. Session cookies are secure, HTTP-only and used only to keep you signed in.

Sharing and selling

We do not sell your information. Cloudflare provides hosting, database, analytics, fallback AI and transactional email services. OpenAI provides the primary recommendation model.

Your choices

You can use the core scanner without an account. To request deletion of an account or saved audits, email support@fifteencopy.com.
