Saju Pals Privacy Policy
Effective date: October 29, 2026
Saju Pals is an app that gives you a Korean-style name and playful readings of your Korean birth chart (saju), told by a guide character. This policy explains what information the app uses, where it goes, and the choices you have.
The short version:
- Your birth details stay on your phone (and in your own iCloud backup, if it's on). We never store them on our server.
- Your name never goes to our AI partner. When you ask for an AI reading or chat, the app sends your chart (not your name, birthday or birthplace).
- We don't sell your information, show ads, or track you across other apps.
- Users under 13 get a version where nothing is sent to us.
"Saju Pals", "we" and "us" mean Frederick Young Lee, an individual based in New York, who makes and runs Saju Pals. You can reach us by email at the addresses in section 15.
1. Information that stays on your phone
When you set up the app, you tell your guide:
- your first name
- your date of birth, and your time of birth if you know it
- your place of birth (you pick a city from a list built into the app; we never use your phone's location)
- your gender, if you choose to share it ("rather not say" is always an option)
From these, the app works out your saju chart, your Korean name, your readings and your daily fortune on your phone. The app also keeps your chosen guide, your visit streak and rewards, your saved readings, your chat with your guide, your settings and your notification schedule on your phone. Notifications are scheduled by your phone; we don't run a notification server.
If you don't create an account and don't turn on AI readings, none of this is sent to us. Deleting the app removes it from your phone. So does Me → Privacy & data → Clear everything on this phone, which also deletes your anonymous session on our server (section 2).
iCloud backup. If you're signed in to iCloud, the app can save your profile and progress (your first name, Korean name, birth details, gender option, guide, outfits, streak and rewards, settings, your story, your unlocked reports and the people you add in Match) in your own iCloud, so they can come back on a new iPhone or after you reinstall. It's private to your Apple ID: we can't see it, and it's never copied to our server. Chat history and friend data aren't included. You can turn it off in Me → Privacy & data → Back up to my iCloud; that deletes the app's iCloud backup. Backup depends on iCloud being on for the app, so a restore isn't guaranteed. Your iPhone's own backups and transfers to a new phone are handled by Apple and your settings, not by this switch.
If you sign in with Apple, the app keeps your sign-in in your phone's Keychain so it can survive a reinstall; signing out or clearing everything removes it.
Day log. If you use the evening "How did today feel?" log, your answers and Your patterns stay on this phone (and in your own iCloud backup, if it's on). They're never sent to us, except that for Plus monthly letters the totals for last month are sent as described in section 2.
To keep free questions fair, the app keeps a count of free questions used on this phone, even after you clear it, and it may remain if you delete and reinstall the app. The count contains no personal information.
2. AI readings and chat (only if you say yes)
Some readings and the chat with your guide ("Ask") are written by an AI model run by our AI partner, Anthropic (the Claude API). For now, AI readings and chat are available only to users 18 and over. Before anything is sent, the app asks for your permission. You can say no and use the offline reading instead, and you can change your mind any time in Me → Privacy & data.
What is sent for an AI reading or chat answer:
- your chart facts (your pillars, five-element counts and similar values the app computed)
- your guide, your gender (if shared) and an age range (13–17 or 18+)
- for chat: what the question is about (for example, today or your work reading), the current saju month, and your last few messages with your guide (up to 10 turns)
- for deep-dive reports: the same chart facts, plus your 10-year luck pillars
- for Today's deeper read (Plus): the same chart facts, plus today's day pillar, the area (money, love or work) and the tone and hours the app worked out
- for your monthly letter (Plus): the same chart facts, plus the month's pillar, your current 10-year chapter, and last month's day-log totals (how many days you marked Good, Okay or Hard), never the days themselves and never the people you've added
- for chat (Plus, if "Let {your guide} remember" is on): up to 10 short notes the guide saved from your earlier chats (see section 6)
What is never sent to our AI partner: your name (the app replaces it with a placeholder, even if you type it into the chat), your Korean name, your date, time or place of birth, your email, or your account details. Your chart is worked out from your birth date and time, so in principle a chart can point back to them; that's one reason we send it only to our AI partner, which doesn't use it to train its models.
Please don't type private details into the chat, such as your full name, address, phone number or health information. What you type is sent to write the answer.
How long it's kept: we don't store the content of AI requests or answers on our servers, including deep-dive reports: those are kept on your phone and, if it's on, in your own iCloud backup. Our servers keep short technical logs (the kind of request, whether it worked, how long it took, and a scrambled version of your user ID) for 14 days, to keep the service running. Our hosting provider's network logs also record the IP address of each request, and keep it for up to 7 days for security. Anthropic deletes requests and answers within 30 days. If its automated safety systems flag a request as breaking its usage rules, it may keep it for up to 2 years for safety review, and it keeps data longer only where the law requires. Anthropic does not use them to train its models.
Your chat history is saved only on your phone. Clear chat deletes it.
Anonymous session. To limit free questions and prevent abuse, the first AI request creates an anonymous session: a random ID stored in your phone's Keychain, with no name or email attached. We store only how many free questions that session has used, plus, for the last answer only, when it was counted and how, so the app can give a question back if it couldn't show you the answer. If you later create an account, the session is linked to it so your free questions carry over. Anonymous sessions with no activity for 12 months are deleted.
3. If you create an account (18+, to connect with friends)
You need an account only to connect with friends (section 6), and only if you're 18 or over. Everything else works without one. You sign in with Apple; there are no passwords, and we don't ask Apple for your email address.
When you create an account, our server stores:
- the ID Apple gives us for your account, and a sign-in token from Apple that we keep only so we can disconnect the app from your Apple ID when you delete your account
- your first name
- a short summary of your chart that your match with friends needs: your type, your day and year animals, and roughly how much of each element your chart shows (none, one or several). Never your birth date, birth time or birthplace. The summary isn't your birthday, but someone who has it and knows roughly how old you are can usually work it out, often to one or two possible dates, so we share it only with the friends you connect with. (Your month and day are kept only while you share your birthday with friends; see section 6.)
- that you're 18 or over (not your age or birth date)
- your guide and outfit choices
- the anonymous session it's linked to (section 2), so your free questions and purchases carry over
- your connections, invites, blocks and reports (section 6)
It is never sent to our AI partner. Delete it any time in Me → Privacy & data → Delete account.
4. Purchases
Purchases (Saju Pals Plus and one-time readings) are available only to users 18 and over. Apple handles the payment; we never see your card details or your Apple ID. You don't need a Saju Pals account to buy.
To unlock what you bought, the app sends our server the purchase records Apple signed on your phone (what you bought, when, the store country and the price). Our server checks Apple's signature, then keeps only, for each purchase: a scrambled purchase ID, which product it was, when a subscription ends, and whether it was refunded. It doesn't keep the signed record, the price or your Apple ID. This is linked to your anonymous session or account, so the app can unlock what you bought and the chat can apply the Plus daily limit. Purchase checks happen only after you've turned on AI or signed in. We never send your name, birth details or chart to Apple or anyone else for purchases.
Subscriptions renew automatically until you cancel them in your Apple ID settings. Deleting your account or the app does not cancel a subscription.
5. Safety
If a message in the chat suggests self-harm, suicide, abuse or danger, the app shows a support card with the 988 Suicide & Crisis Lifeline. When the app catches such a message on your phone, it is not sent to our AI partner, now or later. More at https://sajupals.com/safety.
6. Other things the app does
Name twins. The app may tell you if your Korean name matches a well-known person's name. The list is built into the app, and an updated copy may be downloaded from our server. That download contains none of your information.
Friends (18+, with an account, section 3). You can invite a friend with a link. Before you're connected, both of you agree on a screen that says what the other will see. A connected friend sees only: your first name, your type and day animal, your match together and today's tag for the two of you, and, only if you turn it on, your birthday's month and day. They never see your birth date, birth time, birthplace, full chart, readings or chat, though with your type and animals and a rough idea of your age they could usually work out your birthday. Anyone you send an invite link to can see your first name and type on the link's page. We keep:
- your connections
- invite records (a scrambled code, who sent it and when it expires)
- sparkles waiting to be shown (deleted once shown, or after a day)
- blocks and reports
We don't keep your match: it's worked out when you open it. Friends data is never sent to our AI partner. You can remove a connection, block or report from the friend's page. Reports are reviewed within 24 hours.
A guide who remembers (Plus). If "Let {your guide} remember" is on, the guide may save a short note from a chat (you'll see it, with Undo). Notes are kept on this phone (and in your iCloud backup, if it's on), and up to 10 are sent with a question to write the answer. Notes never include health, money amounts, other people's names or private details, or other sensitive topics. Delete any note, or all of them, in Me → What {your guide} remembers; if Plus ends, notes stay on this phone but aren't used.
Match. People you add yourself in Match by their birthday (a nickname, how you know them, their birthday and, if you add it, their birth time and birth city) are saved on your phone (and in your own iCloud backup, if it's on), never on our server. Their roles, daily tags and good days are worked out on your phone too. They are never sent to us or our AI partner, aren't part of your chat, and aren't saved to your account. Please add only people who are OK with it. Removing a person, or Also clear everything on this phone, deletes them. Shared pair cards never show the other person's name, birthday or how you know them.
Reporting an answer. If you tap Report this answer, your email app opens with that answer's text, addressed to support@sajupals.com. Nothing is sent unless you send the email yourself. We keep report emails like other emails (section 10).
Sharing. When you share your name card, your phone's share sheet sends it where you choose. We don't receive it.
Analytics. The app does not currently use analytics or crash-reporting services. If we add them, we'll update this policy first, and they will never run for users under 13.
No ads, no tracking. We don't show ads, don't use advertising identifiers, and don't track you across other companies' apps or websites.
7. Who we share information with
We don't sell or rent your personal information, and we don't share it for targeted advertising. We share it only with service providers that help us run the app, under contracts that limit how they use it:
| Provider | What for | What they get |
|---|---|---|
| Anthropic | Writing AI readings and chat answers | Chart facts, guide, gender, age range, chat messages (never your name or birth details) |
| Supabase | Accounts, our servers | Account data (section 3) and anonymous sessions (section 2) |
| Apple | Sign in with Apple, iCloud backup (stored in your own iCloud), payments, app distribution | As described in Apple's own privacy policy |
| Cloudflare | Our website and email forwarding | Messages you send to our email addresses |
We may also disclose information if the law requires it, to protect people's safety, or as part of a merger or sale of the business (in which case this policy continues to apply).
8. Children under 13
Saju Pals is not directed to children under 13. We ask for a date of birth because the app needs it to build a chart. On iPhones that support it, the app may also ask Apple for your age range (under 13, 13–17 or 18 and over); you can decline. The answer stays on your phone: it isn't sent to us or backed up, and it's used only to apply these age rules. If the birth date and Apple's age range differ, the younger one counts. If either shows the user is under 13:
- the app does not offer sign-in, AI readings, chat, friends or any feature that sends information to us (the optional iCloud backup goes to the user's own iCloud, which we can't see)
- the Korean name, chart, daily fortune and readings still work, entirely on the phone
- this setting stays on the phone even if the birth date is changed later
Because of this, we do not collect personal information from children under 13. If you're a parent or guardian and believe we have information about your child, email privacy@sajupals.com and we'll delete it.
9. Teens (13–17)
Teens can't create an account, connect with friends or buy anything (based on the birth date and, if shared, Apple's age range; see section 8). AI readings and chat aren't available to users 13–17 yet: teens get the offline reading, which is made on the phone. Before we open AI features to teens, we'll update this policy, and they will come with extra safety rules: age-appropriate content (romance limited to crushes and friendships), regular reminders that the guide is an AI, and our AI partner's rules for services used by people under 18. AI features are never available to children under 13 (see section 8 for how we follow the children's privacy law, COPPA). Where the law in your state requires it, we use the age range Apple provides and follow parental-consent requirements set through the App Store. Parents or guardians can contact privacy@sajupals.com with questions or requests.
10. How long we keep information
| Information | How long |
|---|---|
| Data on your phone | Until you delete it or the app |
| Account data (section 3), including the Apple sign-in token | Until you delete your account; removed from our backups within 30 days |
| iCloud backup | In your own iCloud until you turn backup off or delete it in your iPhone's iCloud settings |
| Anonymous session (free-question count) | 12 months after last use, or when linked to an account |
| AI request content | Not stored by us; up to 30 days at Anthropic (up to 2 years if flagged by its safety systems) |
| Friend connections | Until either of you removes it, or an account is deleted |
| Invite links | Until used, cancelled or expired (7 days), then deleted |
| Sparkles | Until shown, at most 1 day |
| Blocks | Until the blocker deletes their account |
| Reports about friends | Up to 90 days after we review them, or sooner if the reporter's account is deleted |
| Purchase records (scrambled purchase ID, product, subscription end date, refunded or not) | While your anonymous session or account exists; deleted with it |
| Deep-dive reports | On your phone and in your iCloud backup; not on our server |
| Day log and guide notes | On your phone and in your iCloud backup until you delete them; not on our server |
| Monthly letters | On your phone and in your iCloud backup; not on our server |
| Server technical logs | 14 days (IP addresses in our hosting provider's network logs: up to 7 days) |
| Emails you send us | As long as needed to answer, then 2 years |
11. Deleting your data and your choices
- Delete your account: Me → Privacy & data → Delete account. This deletes your account, your friend connections and everything in section 3 (removed from our backups within 30 days), and disconnects the app from your Apple ID. Your iCloud backup is separate: turn it off in the same screen.
- iCloud backup: Me → Privacy & data → Back up to my iCloud. Turning it off deletes the app's iCloud backup.
- Clear everything on this phone: Me → Privacy & data → Clear everything on this phone. This deletes everything the app keeps on this phone and your anonymous session on our server. If you're signed in, it also signs you out on this phone; your account and friend connections stay until you delete your account. Purchases stay with your Apple ID; use Restore purchases. If iCloud backup is on, you can choose to delete that too.
- Turn off AI: Me → Privacy & data, turn off "Let [your guide] use AI". Future readings use the offline version; saved readings stay.
- Clear your chat: in the chat menu, Clear chat.
- Access, correct or delete by email: write to privacy@sajupals.com. We may ask you to confirm it's your account. We answer within 30 days (45 where state law allows). If we can't do what you asked, we'll explain why, and you can reply to appeal.
Depending on where you live (for example, California, Colorado, Connecticut, Virginia and other states), you may have rights to know, access, correct, delete and take a copy of your personal information, and to opt out of its sale or use for targeted advertising. We don't sell it or use it for targeted advertising. We won't treat you differently for using your rights.
Notice at collection (California and other states). This policy is our notice at collection. Sections 1 to 7 list the categories of personal information we collect (identifiers such as your Apple account ID and anonymous session ID; the profile details you enter; purchase records; the content of your chat questions), why we collect them and who receives them, and section 10 says how long we keep each. In the past 12 months we have not sold or shared personal information for targeted advertising, and we don't use or disclose sensitive personal information to infer things about you. An authorized agent may make a request for you; we may ask for proof of that permission.
12. Security
We protect information with encryption in transit and at rest, access limits, and by keeping as little as possible. We keep a written data-retention schedule and security program, and review them every year. No system is perfectly secure, so please keep your devices and sign-in methods secure too. If a security incident affects your information, we'll tell you as the law requires.
13. Where information is stored
Saju Pals is offered in the United States. Information we store is kept in the United States.
14. Changes
If we change this policy, we'll update the date at the top. If a change is significant, we'll tell you in the app before it takes effect.
