Privacy notice

What we collect when you use ai9os.com or sign up for our emails, why, and how to make us stop. Last updated 3 October 2026.

Who we are

AI9OS.COM (UEN 53527859D), a sole proprietorship of Philip Choo in Singapore, runs ai9os.com and is responsible for the personal data described here. Questions, requests and complaints go to privacy@ai9os.com, which also reaches our data protection officer.

What we collect, and why

We do not sell, rent or trade your data, and we do not add you to any list you did not ask to join.

Who processes it for us

Email sign-ups are stored and sent by Brevo, an email service based in France, under its own privacy policy. Payments go through HitPay; hosting is by Cloudflare. Where your data is held outside Singapore, we rely on these providers to protect it to a standard comparable to Singapore's Personal Data Protection Act.

Your choices

How long we keep it

Email sign-ups are kept until you unsubscribe, then removed from our sending list. Purchase records are kept for as long as Singapore tax law requires. Emails to us are kept for as long as the conversation needs, and no longer than two years.

Changes

If this notice changes, the new version goes on this page with a new date. If a change affects how we use the email address you gave us, we will tell you by email first.
