Who we are

SOV17 LLC, Yerevan, Armenia. hello@workbookapi.com.

Your workbooks

The check runs in your browser. Your file, its values, formulas and names are never sent to us.

Anonymous usage

We record page views (referring site, campaign tags), check results as ranges, which Excel features were found and button clicks. Our host adds the country. No cookies, no IP addresses, no profiles.

Early access list

If you join, we store your email, role, how often your model changes, your choice, the time and your country — only to contact you about early access. We do not sell or share it.

Storage

The site and data are hosted by Cloudflare; the form is protected by Cloudflare Turnstile. We keep data until 12 months after early access ends, or delete it sooner on request.

Your rights

Email hello@workbookapi.com to see, correct or delete your data or to leave the list.
