Privacy Policy

Effective May 7, 2026

This is the privacy policy for vaken, an I Ching divination service operated by Life Fine Tuning. We try to keep this short and human. If something is unclear, email oracle@lifefinetuning.com.

What we collect

If you use vaken without signing in: we keep a daily record of your reading, identified by a hash of your IP address and browser user-agent. This is how we enforce the daily free limit. The hash itself cannot be reversed to identify you.

If you sign in with email: we store your email address and a record of every reading you cast (the question, the resulting hexagram, and the AI-generated interpretation). This is so you can come back and review past readings.

If you subscribe: Stripe handles your card data — we never see or store it. We keep a Stripe customer ID and your current plan status (free / monthly / annual) in our database.

Who we share data with

We use four third parties to run vaken:

  • Supabase — hosts our database and handles email sign-in. They process your email and reading history on our behalf.
  • Stripe— handles all payments. They receive your card and billing information directly; we don’t.
  • Resend — delivers the magic-link sign-in email and any other transactional email we send you.
  • DeepSeek — generates the AI interpretation of your hexagram. The text of your question is sent to their API along with the hexagram data.

We do not sell, rent, or trade your information with anyone for marketing purposes. We do not use any analytics or advertising trackers.

How long we keep data

Anonymous reading rows (no signed-in user) are kept for 90 days, then deleted. Signed-in user readings are kept as long as your account exists. Subscription records are kept for 7 years for tax purposes.

Your rights

You can ask us to (a) export everything we have on you, or (b) delete your account and all data, by emailing oracle@lifefinetuning.com. We aim to respond within 7 days. Account deletion is irreversible.

Cookies

vaken uses cookies only for sign-in (Supabase auth) and to remember your active session. We do not use cookies for tracking, advertising, or analytics.

Children

vaken is not intended for users under 18. We do not knowingly collect data from minors.

Changes to this policy

If we change something material, we’ll update the effective date at the top of this page and email all signed-in users. The version on this page is always the current one.
