Privacy Policy
Last updated: August 22, 2026
Saju Lab ("we," "us") is a pre-launch product. This policy covers what we collect right now, on this landing page and reading tool, and why.
What we collect
- Email address - if you join the waitlist or unlock a paid reading. Used only to tell you when Saju Lab launches and, if you purchased something, to keep a record of that purchase.
- Birth date, time, and city - used only in your browser to calculate your chart. We do not send this to our servers or store it anywhere. If you close the tab, it's gone.
- Payment information - we never see or store your card or PayPal details. Payments are handled entirely by PayPal; we only receive confirmation that a payment succeeded, the amount, and the email address PayPal provides for the transaction.
Who we share it with
PayPal (payment processing), Vercel (hosting), and Supabase (database storage). We don't sell your data or share it with advertisers.
Cookies & tracking
We don't use advertising or analytics cookies. The only cookies set come from PayPal's checkout widget itself while you're completing a payment.
Your choices
Want your email removed from our list? Email hello.sajulab@gmail.com and we'll delete it.
Children
Saju Lab isn't directed at children under 13, and we don't knowingly collect their information.
Changes
If this policy changes in a meaningful way, we'll update the date at the top of this page.
