Privacy Policy

The short version

If you only use the free chart and sync, the birthday you type stays in your browser. We do not send it to our server.

If you buy a report, your browser sends our server two short chart codes (made from the two birthdays), any names you typed, an optional short note if you wrote one, and your email, so we can write the report and deliver it. We keep that for up to 12 months and then delete it.

We use no advertising cookies and no tracking cookies. We do not sell your information.

Using the free chart and sync

The birthday you enter, your chart, the people you add to your circle and your results are calculated in your browser and saved only in your browser's local storage on your device. You can clear them any time by clearing the site's data in your browser.

Our server does not receive them. After you buy a report, your browser also saves the link to it in its local storage, so you can find it again on that device only. While a payment is being confirmed, the tab also keeps the payment reference in its session storage, which goes away when you close the tab. What our server does receive is described below.

What we collect when you buy a report

Your browser sends our server: the kind of sync (bias, friend, lover or other), two short chart codes (3 characters each, worked out from the year, month and day pillars of the two birthdays), any names or nicknames you typed (up to 24 characters each), the celebrity you picked if any, and your email address.

The chart codes are made from the birthdays and can be converted back into the birth dates. So when you buy a report, we do receive the two birth dates in coded form. We treat chart codes as personal data and handle them the same way as your email.

At checkout you can also type one optional short note (up to 60 characters) about a song, era or moment you love. It is stored with your order, kept for up to 12 months like the rest, and sent to Google (the Gemini API) together with your nickname and the chart facts so the report can use it. Please do not put personal information in it, such as a full name, an address, a phone number or an account name.

Our server recalculates the chart facts itself from the codes. We do not ask for a birth time or a birthplace.

We store an order record (your email, names, the optional note, chart codes, the payment id, amount and currency, the order status, and where the visit came from: the tag on the link, the site that sent you, your country and your language) and the report that was written. We use the last four to see which posts bring buyers; they are not linked to anything you do before you buy. They are stored in a key-value database run by Upstash (through Vercel KV), under a long random token that is the private link to your report.

We also record the time your report is first opened, so we can apply our refund policy. It is kept with the order and deleted with it.

Payment

Only a product id, a signed order number, and the address to send you back to go from us to Dodo Payments. That return address contains your private report link. Dodo Payments collects your card or wallet details, your email and your billing details on its own page, under its own privacy policy, as the merchant of record. We never see your card number.

From Dodo Payments we receive the payment id, the amount and currency, and whether the payment succeeded or was refunded.

How the report is written

To write the report, our server sends Google (the Gemini API) a text that contains the kind of sync, the names or nicknames you typed or the celebrity's name, the optional note if you wrote one, and chart facts such as the elements, the animal signs and the score. It does not contain your email, your payment details or a birthday.

Google writes the sentences and sends them back to us. Google processes this under its Gemini API terms and its own privacy policy.

Email

We use Resend to send you the link to your report. The email holds your address, the link, and the names you entered, and no chart data. If you ask us to resend a link, we look up your orders by your email address.

If you leave your email in the older reserve-a-report form, we keep it in our database (the most recent 500 are kept) with the sync you were looking at, only to tell you when reports are available. It may also appear in the logs of our hosting provider and in a notification or spreadsheet tool we run to receive these reservations, which keep it on their own schedule.

Anonymous analytics

To see where people drop off, the site counts steps such as visiting, seeing a result, opening the checkout and paying. Each count carries a random code made for your browser tab (it disappears when you close the tab), the name of the step, the sync kind, the score of the chart and the birthday type and animal you looked at, the language, the website that sent you here (the domain only), any campaign tags in the link, and the two-letter country your request came from. There are no names, emails or birthdays in them. The events are also written to our hosting logs and, if we have switched it on, forwarded to a notification tool we operate.

We use no cookies for this and we do not store your name, birthday, email or IP address with these counts. We also use Vercel Web Analytics, which counts page views without cookies.

Our host, Vercel, keeps ordinary server logs (such as IP address and browser type) for security and for running the site, for the period set by Vercel.

Why we use it

To write and deliver the report you paid for, to handle payment and refunds, to answer your questions, to resend your link, to keep the site secure, and to understand in aggregate how the site is used.

We do not sell your personal information, we do not use it for advertising, and we do not build profiles of you.

Who processes it for us

We do not sell your personal information or hand it to anyone for their own use. These companies and tools process it on our behalf, only for the jobs listed:

• Dodo Payments: takes payment as the merchant of record, handles tax, and processes refunds.
• Google (the Gemini API): writes the report text from the names, the optional note and the chart facts.
• Resend: sends the email with your report link.
• Vercel Inc.: hosts the site and our server, and provides cookie-free page-view analytics.
• Upstash (Vercel KV): stores orders, reports and reservation emails.
• Google Fonts: serves the fonts, so your browser contacts Google when a page loads.
• A notification or spreadsheet tool that we run: receives reservation emails, if we have switched it on.
• A notification tool that we operate: receives the anonymous analytics events described above, if we have switched it on.

Transfers outside Korea

We run Saju Sync from Korea, but the companies above work in other countries, mainly the United States, and may store or process your data there. Your browser, our host and these services talk over encrypted connections. By buying a report you accept that your data goes to them for the jobs listed.

How long we keep it

Orders and reports are kept for up to 12 months after purchase and then deleted. This is how long you can reopen your link. You can ask us to delete yours sooner by email.

Some payment records may be kept longer by Dodo Payments, or by us, where the law requires it.

Reservation emails are kept in our database (the most recent 500). The whole list expires 12 months after the most recent reservation is saved, and we delete yours sooner if you ask. Copies in our hosting provider's logs and in a notification or spreadsheet tool follow those providers' own schedules, so deletion there may take longer.

The anonymous counts have no personal data in them and may be kept as long as they are useful.

Your rights

You can ask us to show you what we hold about you, to correct it, or to delete it, at any time. Email admin@dokkaebiworks.com from the address you used to buy, and tell us the order or send us your report link. We aim to reply within 2 business days.

Depending on where you live (for example the EU, the UK, California or Korea) you may have more rights, such as to object to or limit how we process your data, or to complain to your data protection authority. Write to us and we will help.

Security

Your report lives at a private link with a long random token that cannot be guessed. We do not list reports anywhere, and search engines are told not to index them. Anyone who has the link can read the report, so please do not post it.

No system is perfectly secure, so we collect as little as we can: no birth time or place and no card details. The chart codes we do receive can be turned back into a birth date, so we guard them like your email.

Children

Saju Sync is for people who are 16 or older. We do not knowingly collect information from anyone younger. If you think we have, write to us and we will delete it.

Changes to this policy

If we change this policy, we will update the date at the top. If a change affects how we use your email, we will tell you by email before it takes effect.
