Privacy Policy
What we collect, what we don't, and how long we keep it.
Last updated: October 15, 2026
1. The short version
- The free profile is calculated in your browser. Your birth date, birth time and birth city are not sent to our servers and we do not store them.
- We do not use cookies. We do not show ads, and we do not sell or rent personal data.
- We store an email address only if you ask to hear when sales open, buy a report or write to us, and we store birth details only when you start a purchase or put them in a message to us.
- You can ask us to delete your data at any time by writing to hello@sajunstar.com.
2. Who is responsible
Morelife Co., Ltd., registered in South Korea, operates SajuNstar and is the controller of the personal data described here. Our business details are at the bottom of every page. Contact: hello@sajunstar.com.
3. What we process, and for how long
| Data | When | Where it is kept | How long |
|---|---|---|---|
| Birth date, time, city and four-letter type (free profile) | When you fill in the form | Only in your browser's session storage. Not sent to us | Until you close the tab |
| A random value used to pick your daily tarot card | First visit to the result page | Only in your browser's local storage. Not sent to us | Until you clear your browser data |
| The site or campaign that brought you here | First page you open | Your browser's session storage. Attached to your order if you buy | Until you close the tab, or with the order record if you buy |
| Usage statistics: pages opened, sections viewed, whether the form was started, buttons used, referring site or campaign, site language, approximate location (country, region, city), device type, operating system and browser | While you use the site | Our analytics tool. No cookies, no birth details, no email address | 12 months in the tool's reports. The tool may keep data longer |
| Technical logs: IP address, browser type, requested page | Every request | Our hosting provider, for delivery and security | Up to 30 days. The hosting provider may keep security logs longer |
| Error codes: a short fixed code naming a step that failed in your browser, for example that the calculation file did not load. No birth details and no page address | Only when a step fails | Our hosting provider's logs and our database | Up to 30 days in the logs. 30 days in the database |
| Email address (sales notice) | Only if you sign up | Our database, and our email service when the notice is sent | Deleted 30 days after the notice is sent, or 90 days after sign-up if no notice is sent |
| Birth details and type (purchase) | Only when you start a purchase | Our database | Deleted within 48 hours if you do not pay. Kept for 12 months if you do, so that the report can be shown. Deleted within 30 days after a refund |

| The text of your report | When it is produced | Our database | 12 months from purchase. Deleted within 30 days after a refund |
| Messages you send us: your email address and what you write | When you write to us | Our mailbox provider. If you report a calculation error, we may pass the birth date, time and city from your message, without your name or email address, to the AI tool we use to check calculations | As long as needed to handle your request and keep a record of it |
The sales notice and purchases are not available until those features open. Until then we hold none of the data that depends on them.
4. Why we process it
- To provide what you ask for: showing a profile, producing and showing a report you bought (performance of a contract).
- With your consent: sending the one sales notice you signed up for, and storing the birth details you submit when you buy a report. You can withdraw consent at any time.
- For our legitimate interest in keeping the site secure and understanding, in aggregate, how it is used.
- To meet legal duties, such as keeping order records.
5. How reports are written
Paid reports are written by an AI language model operated by Anthropic. To produce a report we send the model the values calculated from your chart (the four pillars, element counts, star sign, four-letter type and the periods of the year) together with our interpretation guide. The free profile does not use this service: its texts were written in advance and your browser selects them.
We do not send the model your name, email address, order number or birth city, and we do not send your birth date or time as such. The four pillars we do send are derived from them: a full chart corresponds to at most one calendar date in each 60-year cycle and to a two-hour window of the day.
Under its commercial terms the provider does not use this data to train its models. It states that it deletes inputs and outputs within 30 days, except for content flagged under its usage policy or where the law requires longer.
To check quality and compliance with our content rules, we ourselves read the first reports we sell and a sample after that.
6. Who processes data for us
We are based in South Korea. We use the service providers below, and they are based in the United States unless the table says otherwise, so the data that reaches us (everything in section 3 except what is kept only in your browser) is transferred to and stored in the United States. The providers other than the payment provider process data on our behalf. The payment provider handles the payment itself under its own privacy policy.
| Provider | What it does for us | Data involved | Location |
|---|---|---|---|
| Vercel Inc. | Hosting, content delivery, usage statistics | Technical logs and usage statistics. Data you submit passes through it on the way to our database | United States, with delivery servers worldwide |
| Supabase Inc. | Database | Sales-notice email addresses; for purchases, birth details, order details and report text | United States |
| Anthropic PBC | AI language model that writes paid reports, and the AI tool we use to check a calculation you report as wrong | Calculated chart values, as described in section 5. For a reported calculation error, the birth date, time and city from your message, without your name or email address | United States |
| Resend (Plus Five Five, Inc.) | Sending the sales notice and operational alerts | Sales-notice email addresses | United States |
| Mailbox provider | Receiving and answering your messages | Messages you send us | Zoho Mail (Zoho Corporation), United States data center |
| Payment provider | Checkout, tax handling, receipts, refunds | Order details and the payment details you give it | To be named here before sales open |
We share data with authorities only where the law requires it.
7. Cookies and browser storage
We do not set cookies. We use your browser's session storage to hold the details you type and the site that referred you while the tab is open. When you go back to add a birth time or type, it also briefly holds which field to put the cursor in. We use local storage to hold one random value for the daily tarot card. Neither is used to track you across sites. Our usage statistics count visits without cookies, using a value derived from each request and reset every day.
8. What a shared card contains
If you share your result, the picture and the link contain at most four things: your Day Master, your star sign, your four-letter type and the card of the day. The card of the day is drawn at random and does not come from your birth details. If you did not enter a birth time and the missing time could change your Day Master or star sign, the picture also says that some values are provisional. They do not contain your birth date, birth time, birth city or full chart, but they narrow them down. Someone who knows your year of birth could narrow your birthday to about three dates. Someone who knows your birthday could narrow your year of birth to about nine candidates, or to one or two if they also know your rough age. A shared picture or link is not tied to you, and we cannot recall or delete one once it has been posted.
9. Your choices and rights
You can ask us for a copy of the personal data we hold about you, ask us to correct or delete it, object to or restrict its use, or withdraw consent you have given. Write to hello@sajunstar.com from the email address the request is about. We act on deletion requests without undue delay and do not charge for them.
If you ask us to delete the birth details behind a report you bought, the report can no longer be shown. Order records that the law requires us to keep are deleted when that period ends.
Depending on where you live you may have further rights, including the right to complain to your local data protection authority.
10. Age
SajuNstar is for people 18 or older. We do not knowingly collect data from anyone younger. If you believe a younger person has given us data, tell us and we will delete it.
11. Security
Data is encrypted in transit. Visitors' browsers never receive a database key; only our server code, and we ourselves when we administer the service, can read or write the database. Report pages are opened with a long random token and are marked so that search engines do not index them. No method of storage or transmission is completely secure, and we cannot promise absolute security.
12. Changes to this policy
If we change how we handle personal data we will update this page and its date. If a change is significant we will give notice on the site before it applies.
