Dairy Dynasty — Privacy Policy

Effective date: November 11, 2026

NDJ LABS ("the developer") respects the privacy of everyone who plays Dairy Dynasty ("the game").

1. What we collect

• The game is played with an account. On the first start you make one as a guest (anonymous), with Google or with Apple, and your farm is backed up to it automatically.
• There are no ads and no analytics tools. No real name or phone number is collected; a game nickname is, for the friend card and for the game to call you by (the email and name from Google, when you start or link with it, are in the table).
• Friends involve no photos. What a player chooses is a game nickname (2 to 10 Hangul, Latin, digit, kana or kanji characters; a single kanji also works; a new account chooses it after the first delivery, a name the game suggests or one of its own, and it is kept even without using friends — please use a nickname, not your real name) and, from 2.3.7, notes to friends (one line of up to 60 characters). A name is checked on the server for its letters, length and blocked words; a note for blocked words, passing for the developer, contact details, messengers, links and long numbers; only what passes is stored and passed on. Guestbook lines are chosen from a fixed list. A note is seen only by the friend who gets it, is deleted after 30 days, and its sender is never told whether it was read. Before the first note a player agrees to the note rules. Players can block anyone, and can report a name or a note in the app (the reported friend is blocked at once); the developer reviews reports and may limit an account's friend features.
• Reports can also be sent to the contact below.
• Album photos stay on your device. Only when you tap Share in the album does one photo go to the app you pick, never to the developer's server (whether it carries your friend code's QR is your choice each time, off by default). Sending an invite link likewise hands the text to the app you pick and leaves no record on the server. Paste in My code reads the clipboard only when you tap it and keeps or sends nothing it read (a code found is just put in the box).
• Send Feedback: from Settings you can send the developer a bug report, a suggestion, a payment question or anything else. Your message goes with the app version, device type, operating system, language and level, under your account ID, as the screen says before you send. In a bug report you can tick a box to send this device's error log too (off by default). Your save file and email address are not sent. You can send up to 5 a day; not every message gets a reply. A farm with no account can't send from the app: please write to the contact below.
• (2.4.5) Visiting a friend's farm: so your friends can look around your farm in 3D, while you have at least one friend and visits are on, one copy of how your farm is drawn (fields and crops, buildings and decorations with their looks, the work and finished goods in buildings, animals, how your staff look, trees, town buildings and roads, the progress that shapes it such as your level, skills and stories, figures only as far as they show — the hay in a trough, the trucks a company runs — and the app version) is kept on the server (sent only when it changed, at most every 30 minutes — a new one replaces the last). It never includes the names of your farm, animals or staff, gold, diamonds, stored goods, income amounts, staff pay, reviews or abilities, the achievements list, the diary, or account details. Only your friends can see it; someone you unfriend or block can't load it again (a visit they already have open stays until they close it). Turning visits off under Friends → My code deletes the copy at once; deleting your account deletes it too.

2. Information kept on the device

• The farm is saved on the device as well, and with an account it is backed up to the cloud automatically.
• Depending on device settings, the save may be included in the operating system's cloud backup (Android Auto Backup, iCloud device backup) or a device transfer. Google or Apple keep those copies under your own account; the developer cannot see them. The game album's photos are left out of Android cloud backups.
• From app 2.4.8 the login token is kept out of cloud and device backups (only a direct phone-to-phone transfer on Android may carry it). In earlier versions it may be included in a backup, depending on the device's settings. So from app 2.4.8 a device restored from a backup has to sign in again. A guest account has no way to sign in again: from app 2.4.8 the restored farm goes on under a new guest account, and its friends list does not carry over.
• The nickname you give a friend stays on that device only and is never sent. A notice's "Don't show again" is also kept on the device only.
• To tell you a friend's news (a new level, a first company, more achievements), the figures last seen on their friend card are kept on that device only, and cleared when you sign out or delete the account.
• The error log (what went wrong in the app, and when) is kept on the device. It goes to the server only when you tick it in a bug report under Send Feedback.
• Notifications are scheduled on the device and never sent off it.

3. Payments

• Nothing is sold inside this version of the app. There is no payment screen, the app never connects to a store's billing, and no payment information is collected.

4. Processors and transfers abroad

• The developer does not sell personal information or give it to third parties for their own use; the only one processing it on the developer's behalf is Google LLC (below). A friend card's farm figures and (2.4.5) your farm's look for visits are seen only by your friends, and letters and notes only by the friend who receives them (the name, face and level can be checked before a request by someone who knows your friend code).
• Sign-in, cloud storage and the friends server (Cloud Functions) are entrusted to Google LLC (Firebase). On the first start, with the notice of what is processed, a separate consent to the transfer abroad below is asked; without it no account can be made and the game can't start (Korean Personal Information Protection Act, Article 28-8).
• Recipient: Google LLC (Firebase) · Contact: firebase.google.com/support
• Countries: the United States (sign-in); South Korea, Seoul region (farm backup, friend data and the friends server, operated by Google LLC)
• When and how: on start, on each backup, when a game nickname is chosen, when the friends window opens, and while the game is in use if you have friends, over an encrypted connection (HTTPS)
• Items: account ID, IP address and device info during sign-in, farm records, friend card, name register, lists, requests, letters and notes, (2.4.5) your farm's look for friends' visits, the developer's gift records, reports, Send Feedback messages and what goes with them, the game's language, restrictions, deletion marks, (with Google) email address, name, profile photo address and Google user ID, (with Apple) Apple user ID
• Purpose: sign-in, cloud backup and restore, moving devices, friends and the game calling you by your nickname
• Retention: as in the table in section 1 (Google's logs a few weeks; up to 180 days for Google's systems to clear after deletion)
• How to refuse and what follows: decline on the start screen's consent card and no account is made. After starting, withdraw any time with Settings → Online → Manage → Delete account.
• Linking a Google or Apple account later to an account you already have asks its own separate consents (collection and use, transfer abroad). Without them nothing is linked and your account goes on as before. A linked account stays until the account is deleted. Signing out (Settings → Online → Manage → Sign out) clears the sign-in and the farm's records on this device (the game album's photos stay); the account and its farm stay on the server for the same account to load again.
• Google's and Apple's sign-in windows are handled by those companies under their own policies; only the items in the table in section 1 reach this app.

5. Children and minors

• The game is not aimed at children.
• The game collects only the items in the table in section 1. No phone number, address or date of birth is asked for; an email address and name are received only when you start with or link a Google account. Nothing is sold inside the app, so there are no payments.
• No age is asked. In earlier versions choosing "under 14" locked online out of that device for good, with no way back, so the question was removed.
• Under Korean law, personal information of a child under 14 is not processed without a legal guardian's consent. If we learn that a child under 14 has used the game, or a guardian asks, the account and its farm are deleted without delay (contact below). They can also be deleted in the app at any time (Settings → Online → Manage → Delete account).

6. Your rights and deletion

• You can delete the account in the app any time: Settings → Online → Manage → Delete account (confirmed twice). The account, the farm's cloud backup, the friend card, friend list, requests, blocks, letters and notes (including ones you sent), the friend code, your farm's look for friends' visits, the developer's gift records and your Send Feedback messages are deleted, and this device's farm is deleted too, so you start fresh. If a deletion is interrupted it continues the next time the app opens (once the deletion's mark reaches the server, the server finishes it).
• Ending a friendship deletes it, blocking someone deletes your friendship and friend requests with them, renewing your friend code deletes the old code, and (2.4.5) turning friends' visits off deletes your farm's look — each at once.
• If you deleted the app or can't use it, ask at https://ndj-labs.web.app/dairydynasty/delete/ or ndjlabs@gmail.com. With your account ID we delete within 7 days of confirming and tell you the result. The account ID is shown and can be copied in Settings → Online → Manage → Account ID (when the app can't reach the account, the deletion screen shows it).
• For access, correction or suspension of processing, contact us below.

7. Security

• All traffic between the device and the servers is encrypted (HTTPS).
• Security rules let only the account itself read its farm backup and friend records; a friend card's farm figures and the farm's look for visits can be read only by the account's friends (the look is sent and deleted only through the server function), and a friend code lookup shows only the name, face and level. Friendships, requests, letters, notes and the developer's gifts are written only by the server function, so only the recipient can accept a request and blocks and once-a-day limits are kept on the server.
• Friend codes can't be listed; only the exact code finds one.

8. Users in the EU, the EEA and the UK

If you are in the European Union, the European Economic Area or the United Kingdom, the General Data Protection Regulation (GDPR; in the UK, the UK GDPR) also gives you the following.

• Controller: NDJ LABS (ndjlabs@gmail.com).
• Legal bases (why your data may be processed):
• The account, cloud backup and restore, moving devices, friends, letters and notes, the developer's gifts, and the Google or Apple user ID when you choose to link one: to provide the game you asked for (performance of a contract, Article 6(1)(b)).
• The email address, name and profile photo address Google sends with a link: our legitimate interest in showing you which account is linked (the email, partly hidden) and in finding your account when you ask us for help (Article 6(1)(f)).
• Sign-in security and abuse prevention (the IP address and device info), checking names and notes, daily limits, reviewing reports and limiting an account's friend features: our legitimate interest in keeping the game safe for everyone (Article 6(1)(f)). You can object to processing based on legitimate interests; tell us why at the contact below.
• Send Feedback messages and what goes with them, the ticked error log included: our legitimate interest in fixing bugs and answering questions so the game keeps running (Article 6(1)(f)).
• The game's language: our legitimate interest in supporting players by language and running the game (Article 6(1)(f)).
• Finishing an account deletion (the deletion mark) and answering requests to exercise your rights: legal obligations under the GDPR or other EU, Member State or UK law that applies to us (Article 6(1)(c)).
• The consents the start screen and a later link ask for are requested under Korean law; under the GDPR and the UK GDPR, the processing rests on the bases above.
• Providing data: no law requires you to give us data. The account and its backup are needed to play (the contract), and so are a new account's game nickname and friend card (chosen after the first delivery); making friends, notes and Google or Apple linking are optional, and without them only those features are off.
• Transfers: Farm backups and friend data are stored in South Korea (Seoul), which the European Commission and the UK have recognised as protecting personal data adequately (adequacy decisions). Sign-in is processed by Google LLC in the United States, which takes part in the EU–U.S. Data Privacy Framework and its UK Extension. Where they are needed, Google's data processing terms for Firebase and Google Cloud also provide standard contractual clauses (with the UK's safeguards).
• Your rights: you can ask for access to your data, its correction or deletion, restriction of its processing and a copy in a portable format, and object as above. We act without undue delay and within one month (an account deletion request within 7 days, section 6). Account deletion is also available in the app (section 6). You can complain to us first at ndjlabs@gmail.com, and to the data protection authority where you live or work (in the UK, the Information Commissioner's Office).
• Automated decisions: no decision with legal or similarly significant effects is made about you solely by automated processing. The automatic checks only decide whether a name or a note is accepted.
