Privacy Policy
Last updated: 2026-09-06
What we collect
Birth date, birth time when you give one, birth place, and sex — Saju uses sex to calculate your 10-year luck cycles. All of this is used only to compute your chart. An email address only if you ask to be notified about a report or you buy one. An anonymous identifier stored in a cookie so you can return to your own reading.
What we do not collect
No account, no password, no name, no advertising identifiers, and no third-party analytics or tracking scripts on this site.
How your data is used
Birth data is used to compute your chart and to generate your reading. To write the reading text, we send your chart data to Anthropic, the AI model provider. We also use a hosting provider to run this site and a database provider to store your data. These are processors working on our behalf — we do not sell your data or share it with anyone else.
Retention and deletion
We keep your birth profile, its readings, and any email address tied to it until you delete them; there is no automatic expiry. You can delete your birth profile and every reading generated from it at any time from your reading page — this removes them from our database immediately. Chart data sent to Anthropic to generate your reading is retained by Anthropic under its own policy — normally deleted within 30 days, but if automatically flagged as violating Anthropic's usage policy, retained for up to 2 years, with classification scores kept up to 7 years. That retention is separate from, and independent of, what we store ourselves. See Anthropic's data retention policy at https://privacy.claude.com/en/articles/7996866-how-long-do-you-store-my-organization-s-data.
Payment
Payments are handled by the applicable Paddle contracting entity, which depends on your country, as our merchant of record — see Paddle's buyer terms at https://www.paddle.com/legal/buyer-terms. Card details never reach our servers.
