Privacy
Last updated 11 August 2026
Saju Ink asks for a birth date, a birth time and, for some readings, sex at birth. It uses them to calculate a chart and then to write that chart up. It does not keep them. There is no account to make, nothing to log into, and nothing on this site that follows you anywhere else.
What we do not collect
No accounts, no passwords. No cookies are set by this site. No analytics, no tracking pixels, no advertising, no session identifiers, no fingerprint. The only personal detail this site ever asks for is an email address, and only if you offer one — see the waitlist below. Everything else here works without it.
Your birth details
When you submit the form, your birth details are placed in the address of the results page — for example /reading?d=1990-03-15&t=14:30. The chart is recalculated from that address every time the page is loaded. There is no database behind this site and nothing is written to one.
Two honest consequences of putting the details in the URL:
- The link is your reading. It stays in your browser history, and anyone you send it to can open the same chart. Nothing else is needed to view it, so treat it the way you would treat any link that says something about you.
- Like every website, this one runs on a hosting provider that keeps standard server access logs, and a request URL is part of a log line. Your birth date and time can therefore appear in those logs for as long as the provider retains them. We read them only when something is broken.
The interpretation step
The chart itself is arithmetic and happens on our own server. Writing it up in English is a separate step, and depending on the reading it is done one of two ways.
Some readings are assembled from text written by hand and shipped with the site. In that case nothing leaves our server at all.
The longer readings are written by a language model run by Anthropic. For those, the calculated chart and the birth date and time it came from are sent to Anthropic's API as text. Nothing else goes with them — no name, no email, no account, no IP-based profile, because we do not have any of those. Anthropic's API terms state that inputs submitted through the API are not used to train their models. Anthropic is a United States company, so that request leaves your country if you are outside the US.
The waitlist
The full readings are not open yet. If you leave an address to be told when they are, it is used for that message and nothing else — no newsletter, no second product, no passing it on.
Two things happen to it. It is saved in your browser's local storage, so a later visit shows that you already signed up instead of asking again; clearing your browsing data removes it. And it is written to our server log, which at this stage is how the list is actually read — there is no mailing provider behind the form yet. Those log entries expire when the hosting provider rotates them. If you would rather not wait for that, write to us and the address will not be used.
Who else is involved
Two parties, both listed above: the hosting provider that serves the pages and keeps the access logs, and Anthropic for the interpretation step. There is no third one, and no mailing-list provider. We do not sell, rent or share anything.
Your rights
Rights of access, correction and deletion attach to stored personal data. Charts are not stored at all, so for those there is no record to retrieve or erase — if you want a reading to stop existing on your side, delete the link. A waitlist address is the one thing that persists, in the two places named above; ask and we will tell you what is there, correct it, or stop using it. Either way, write to hello@sajuink.com.
Children
Saju Ink is written for adults and is not directed at children. Please do not submit another person's birth details without their agreement.
Changes
If what the site does with data changes, this page changes with it and the date at the top moves. Paid readings and saved charts are both possible futures for this site, and either would mean holding something we do not hold today; neither will arrive quietly.
