The free checker

The checker runs entirely in your browser. The text you type and the zip files you open are never sent to us or to anyone else.

What we count

We keep anonymous daily totals of these events: page views, checker runs (manual or zip), whether a check found errors, sample downloads and quote-button clicks. Each request carries only the event name. We do not set cookies and do not store IP addresses, user agents, identifiers, text or file names.

Hosting

The site is hosted on Cloudflare Pages; the daily totals are stored in Cloudflare D1. Cloudflare processes network requests (including IP addresses) to deliver and protect the site under its own privacy policy. We do not receive those logs.

Quote emails

If you email us for a quote, Fizz Labs receives your email address and whatever you send (for example your listing text). We use it only to answer you and deliver the order, and we delete it on request. We never sell or share it.

Payments

Payment is not open yet. When it opens, payment details will be handled by the payment provider, not stored by us; this notice will be updated first.

Your requests

Email support@fizzlabs.ai to ask what we hold about you or to have it deleted.
