Privacy notes

Know what each free tool does with your input.

Most Nueralhook tools run entirely in your browser. A small number fetch a public website URL or keyword suggestions because that is the job of the tool.

17 file tools

Images are processed locally with browser canvas APIs.

81 text tools

Text, code, numbers, and generated output stay in the browser.

2 lookup tools

These tools request public web or autocomplete data to produce the result.

Email access and the free-tool meter

Your first two successful tool results in each 24-hour window do not require an email. Nueralhook stores an anonymous browser token and the number of completed uses. Only a one-way hash of that token is stored in the database. Your tool input and generated output are not added to the meter record.

Entering an email unlocks all free tools in that browser. The access cookie can last up to 400 days, which is the practical browser limit. If your browser clears it, enter the same email again. Your email is stored for access; the separate marketing checkbox is optional and starts unchecked. To request deletion, email [email protected].

Site analytics and privacy choices

Cloudflare receives request data needed to deliver and protect this site and provides aggregate traffic counts. If you choose Accept analytics, Nueralhook also loads Cloudflare Web Analytics to measure anonymous page views and page-speed signals such as Core Web Vitals. Cloudflare Web Analytics does not use cookies, local storage, fingerprinting, advertising identifiers, or your tool input.

Nueralhook stores your privacy choice in this browser so you are not asked on every page. Choosing Essential only leaves browser analytics off. You can change your choice at any time with the Privacy choices control in the footer.

Public URL fetch

The scanner sends the public URL you enter to Nueralhook so the edge function can fetch public HTML and score it.

Website SEO scanPaste your address and see what is broken.

Autocomplete lookup

The keyword finder may query an autocomplete source for public keyword ideas, then falls back to local phrases.

Patient keyword finderFind phrases people type before they book.

Browser-local utility
