Privacy Policy
Last updated 21 June 2026
This page explains, in plain English, what personal data Kehai collects, why, how long it is kept, and the rights you have over it.
Questions or requests: privacy@kehai.tax
Who we are
Kehai is an indirect-tax change-control tool operated by Nahim Sayed, who acts as the data controller for the personal data described here. For any privacy question, or to exercise your rights, email privacy@kehai.tax.
What we collect
When you submit the contact form we receive your email address, the page you submitted it from, and your browser's user-agent string - nothing more. If you hold a private workspace account we also process your account email and a sign-in session. For visitor numbers we use Vercel Analytics, which is cookieless and records only aggregate, anonymous page views; it does not track you across other sites or build a profile of you.
Why we use it
We use your contact details only to reply to your enquiry and, where relevant, to follow up about Kehai. The legal basis is your consent when you submit the form and our legitimate interest in responding to you. We never sell your data or share it for advertising.
How long we keep it
Contact details are kept while we are in touch and for a reasonable period afterwards, then deleted when no longer needed or on request. Account data is kept for the life of your workspace account.
Who processes it
A small set of providers process data on our behalf to run the service: Vercel (hosting and cookieless analytics), Neon (the Postgres database), and the email and Slack notifications that alert us to a new enquiry. Each acts only on our instructions.
Where it is stored
Data is stored on infrastructure located in the European Union.
Cookies
The public site sets no marketing or tracking cookies, so there is no cookie banner to click through. The only cookie Kehai sets is a sign-in session cookie, and only if you log in to a private workspace.
Your rights
Under the GDPR you can ask us to access, correct, delete or export your personal data, or object to how we use it. Email privacy@kehai.tax and we will action it. You also have the right to complain to your local data-protection authority.
Changes to this policy
If our practices change we will update this page; the date at the top always reflects the current version.
