Privacy policy
Last updated November 10, 2026
What Ketika collects when you use Ketika, why, and what you can do about it. In short: as little as we can, never sold, analytics only if you agree.
What we collect
- Your email address, when you ask for a free lesson by email, join a waiting list, buy a course, or sign in.
- Your purchases and lesson progress, so your library and "pick up where you left off" work.
- Technical data we need to run the site securely: a hashed form of your IP address for rate limiting, your browser type, and the time of requests. We don't store raw IP addresses.
- Campaign details in the link you arrived from (such as utm_source), stored with a sign-up or order so we know which ads are worth paying for.
What we don't collect
We don't see or store your card details; our payment provider, Stripe, handles them. We don't ask for your name, phone number, or postal address unless the law of your country requires it for an invoice.
Why we use it
- To give you what you asked for: send the free lesson, deliver your course, and keep you signed in.
- To meet legal duties, such as keeping tax and accounting records of orders.
- To keep the site safe, for example by limiting repeated sign-in attempts.
- With your consent only: update emails, analytics, and ad measurement. You can withdraw consent at any time.
Cookies
- A session cookie keeps you signed in. It is necessary and is set only when you sign in.
- A preference stored in your browser remembers your edition, your cookie choice, and where you stopped in the audio.
- Analytics and advertising cookies are set only after you choose Accept in the cookie banner. You can change your choice anytime with the "Cookie settings" link in the footer.
Who processes your data
We use a small number of providers to run the service: our hosting provider, our email provider, our payment provider (Stripe) and, only with your consent, analytics and ad-measurement providers. Each one gets only what it needs for its job. Some of them may process data in countries other than yours.
We don't sell your data
We don't sell your personal information, and we don't give it to anyone for their own marketing.
How long we keep it
Sign-ups are kept until you unsubscribe or ask us to delete them. Orders are kept as long as tax and accounting rules require. Sign-in sessions end after 90 days without use.
Children
The courses are for people 18 and older. We don't knowingly collect data from children. If you think a child has given us their email, write to us and we will delete it.
Your rights
You can ask for a copy of your data, ask us to correct or delete it, or withdraw consent for emails at any time. Write to support@nftai.pro and we will answer within 30 days. Depending on where you live, you may have more rights under your country's or state's privacy law, including the right to complain to your data protection authority. We respect those rights wherever they apply.
