Mochi Pets

Privacy Policy

Effective date: November 13, 2026

What we collect

Mochi Pets (“the app”) has no servers of its own. It never sends your data to us or to anyone else, and never uses it for ads or analytics, or sells it. The exceptions are Friends, study groups, chat and Plus gifts, which you use only if you turn on Friends yourself, and your Study Hall window, which appears only if you light it yourself (see below): your friend card, photo avatar, groups, group avatars, group background photos, messages, gift records, invite records, Study Hall window and stars are stored in Apple's public iCloud database, where we (the developer) can see them too.

Data the app uses on your device

The data below is only used on your device. Anything that needs permission asks you first, and you can turn it off anytime in the iPhone Settings app.

Pets and game progress
Pets, coins, items, room decorations, achievements, Daily Quests and so on are stored in the app.
Focus history
The length, subject, task name, to-dos and reflections of each focus session, used for your stats and Weekly Report.
Steps (Apple Health, read)
Read only after you agree, to exchange steps for hatching tickets. Only steps are read, no other health data; steps you enter by hand don't count.
Mindful Minutes (Apple Health, write)
Off by default. If you turn it on in Settings, finishing the breathing exercise before a focus session writes Mindful Minutes to the Health app. The app never reads this data.
Camera
Used only in Photo Mode and Study Check-in to take photos of you and your pet. For AR photos, the app finds your desk or floor on the device so your pet can stand on it. Everything is processed on your device and never uploaded.
Photos
Saving to Photos only adds photos and never reads your library. When you choose a photo for a background, the system photo picker gives the app only the photo you pick. Room and home backgrounds stay on your iPhone (and in your own iCloud); only a photo you choose as a photo avatar, a group avatar or a study group's classroom background is stored in the public iCloud database (see “Friends” and “Study Groups”).
Notifications
Used for focus and break reminders and the reminders you set yourself (such as your Study Schedule, Review Reminders and monthly recaps); these are scheduled on your device. Once you turn on Friends, friend activity and new messages are delivered as push notifications through Apple's iCloud, showing the sender's nickname and the message. You can turn off chat notifications for each group in its settings. We never send ads or marketing messages.
Calendar (write only)
Off by default. If you turn on “Add Focus Sessions to Calendar”, each finished session is added to your default calendar. The app only asks for write-only access and can't see anything in your calendar.
Screen Time (Block Apps While Focusing)
If you turn this on, the app uses Apple's Screen Time permission to block the apps you choose while a focus timer is running. The app can't see which apps you chose or your usage history.
Siri, Shortcuts, widgets and the Dynamic Island
Run on your device to start focusing quickly or show your pet and the countdown.
Apple Watch
If your iPhone is paired with an Apple Watch, the two send each other your focus status and times, task name and subject, your pet's look and name, today's focus minutes, your streak, the coins and XP you earned, and whether you have Plus, so they can be shown on the watch and its face. This data travels only between your own iPhone and Apple Watch and is never sent to us. The background you pick for the watch screen is stored only on the watch.

iCloud Sync

When iCloud Sync is on, your data is stored in a private area of your own iCloud, using the Apple Account you're signed in with, so it's still there when you get a new iPhone. Apple keeps this data and we can't read it. You can turn sync off anytime in the app's Settings.

Friends (only if you turn it on)

Friends is off by default. Once you pick a nickname and turn it on, the app stores a “friend card” in the public database of Apple's iCloud. It contains only your nickname, friend code, your companion pet's look and name, whether you're studying right now (and until when), minutes studied today and this week, your streak, whether your pet is awake at home, and how many of each snack is in your bag. Anyone with your friend code can see this card, and so can we (the developer). Requests, pats, snacks and snack thefts between you and your friends are stored there as small records so the other person gets them when they open the app.

Pet visits (from version 1.0.9): when you send one of your pets to visit a friend, the app stores a small record there for that friend with the pet's name and look (species, growth stage, outfit and colors), an ID for the visit and when the pet comes home. When your friend pets your visiting pet or gives it a snack, a small record is stored for you too. Who is visiting whom, and the postcards your pets bring home, stay on your phone and are never uploaded.

Apart from a photo avatar, your friend card never includes your notes, subjects, photos, health data or any other personal information. Photo avatars are a Plus feature: only friends and people in your groups can see them. Before one is added, it's checked on your iPhone (this check runs when Sensitive Content Warning or Communication Safety is turned on, and the photo isn't sent to Apple) and cropped to a 512×512 JPEG with no location or similar data. Offensive words in nicknames, pet names and group names are replaced with asterisks. You can remove or block a friend anytime; if a nickname or group name is inappropriate, email us and we may delete that friend card or group. When you turn Friends off, your friend card is deleted, you leave all study groups (groups you created are disbanded), and the messages you've sent are unsent. If you're offline at the time, this finishes the next time you open the app. Your friends list stays in your own app, so your friends are still there if you turn it back on.

Inviting friends: if you add your first friend within 7 days of starting, the app puts an invite record in the same public database. It contains only the friend code of the person who invited you, the times it was created and when you completed a focus session, and a code derived from your iCloud account that can't be reversed. The record makes sure each account gets the reward only once. It doesn't include your nickname or friend code, and turning off Friends doesn't delete it. To have it deleted, email us.

Study Groups (after you turn on Friends)

When you create a study group or join one with a group code, the app stores in the same public database: the group's name, icon and classroom theme, the creator's nickname and friend code, the friend codes the creator has removed, and a member record for you (nickname, friend code, when you joined, and whether you only show if you studied). Anyone with the group code can see the group, its member list and its members' friend cards (described above). If you turn on “Only Show If I Studied,” groups only show whether you studied today. Study sessions, joining a session, cheers and snack thefts are stored there as small records too.

If the creator of a group is a Plus member, they can add a photo as the classroom background. The photo is resized and stored in the same public database, where the group's members and we (the developer) can see it. Before it's added, the app checks the photo on the iPhone with Apple's Sensitive Content Analysis and won't add one that looks inappropriate (this check runs when Sensitive Content Warning or Communication Safety is turned on, and the photo isn't sent to Apple). Members can turn the photo off (only their own classroom goes back to the theme) or report it: a report sends us the group code, the photo's ID, both of your friend codes and the reason, and the photo no longer appears on your screen. A photo reported by three different people is hidden for everyone. We review reports and delete photos from the database when needed. When the creator changes or removes the photo, or disbands the group, the previous photo is deleted.

Group avatars work the same way: if the creator is a Plus member, they can also add a photo as the group avatar, which the group's members and we (the developer) can see; without one, the group's icon is shown. The photo is checked, reported, hidden and deleted the same way as the classroom background.

There's no way to search for groups or strangers. You can leave a group or block someone in it anytime. The creator can remove people or disband the group; disbanding deletes the group record, and leaving deletes your member record.

Chat (after you turn on Friends)

Friends can send each other direct messages, and members of a study group can chat in the group. What you say in a group's classroom is also a group message, shown above your pet for 15 minutes. Messages can only contain text and emoji (up to 200 characters each), not photos; links and phone numbers are shown as plain text and can't be tapped. Each message is stored with your nickname, friend code and the time it was sent in the public database of Apple's iCloud: the recipient (or, in a group, the group's members) can see it, and so can we (the developer). Messages aren't end-to-end encrypted, so please don't share your address, phone number, passwords or other personal information.

Messages are kept for 30 days: the app only shows messages from the last 30 days, and your app deletes the messages you sent more than 30 days ago. You can unsend your own messages anytime. In the public database, only the sender can delete a message, so messages others send you are deleted by their app after 30 days, or when they unsend them or turn off Friends. Until then, blocking someone hides their messages from you.

Before a message is sent, the app replaces offensive words with asterisks. You can press and hold a message to report it: a report sends us the message, both of your friend codes and the reason, and the message no longer appears on your screen. A group message reported by three different people is hidden for everyone. We review reports and delete messages from the database when needed. You can also block someone: you won't see their messages, and they can't send you direct messages. See “Notifications” above for chat notifications.

Gifting Plus to a friend

You can buy 1 month or 1 year of Plus for a friend from their page. Apple handles the purchase, and we never get your payment details. After the purchase, the app stores a gift record in the public database of Apple's iCloud: your and your friend's nicknames and friend codes, whether you gave 1 month or 1 year, the note you wrote (up to 50 characters, with offensive words masked), when you sent it, and Apple's signed purchase record (which contains the transaction ID, product, purchase date, country or region and price, but no name or payment details). Your friend's app uses the signed record to check on their iPhone that the gift is real and meant for them. Your friend and we (the developer) can see this record.

The gift starts when your friend opens it, and the time they open it is stored in their own data (and in their own iCloud if they use iCloud Sync). Gifts can't be exchanged for anything else, and refunds go only to the person who bought the gift. After a refund, your app marks the gift record, and your friend's gifted Plus ends.

Raise with a Friend (Plus)

When you invite a friend to raise a pet with you, that pet's data (name, look, status, level and each person's XP) is stored in a shared area of your own iCloud and shared with the people you invite through Apple's iCloud sharing. Only you and the people you invite can see it; we can't read it. Sharing ends when you stop raising together.

Study Hall (only visible if you turn it on)

You can look at the Study Hall building without turning anything on. If you turn on “Light My Window”, the app puts one window in Apple iCloud’s public database: a random ID (derived from your anonymous iCloud user ID), how your pet looks (species, stage, color, outfit), your window decor, and when you started focusing and expect to finish. Anyone using the app can see this, and so can we. A window never includes your nickname, pet name, friend code, location, subjects or notes, and nobody can type anything.

Others can send you stars. A star only records which window it went to and when; you can’t see who sent it, and it can’t contain text. The app deletes stars you sent after 7 days. You can turn this off at any time in Study Hall › My Window; your window and the stars you sent are deleted right away. If you reinstalled the app, email us to delete stars you sent earlier.

In-app purchases

Mochi Pets Plus subscriptions and purchases (including Plus you give to a friend) are handled by Apple. The app only checks on your device whether you have Plus, and never gets your payment details, name or email. Please contact Apple for refunds and subscription management.

Backups

You can export a backup file in Settings that contains your pets, coins, items, room, history and photos. You keep the file yourself (for example in Files or iCloud Drive); we never receive it.

Children and students

The app is made for students. Apart from the nickname, friend card, messages, photo avatar, group avatar and group background photo you share when you turn on Friends yourself, it doesn't collect any personal information. Friends is off by default and there's no way to search for strangers: people can only connect and message each other by exchanging friend codes, and can only join a study group and its chat with the group code. Offensive words are masked, anyone can report a message, photo avatar, group avatar or group background photo or block someone, and you can remove anyone, leave any group or turn Friends off anytime. If you're a parent with questions about your child using the app, please contact us.

Deleting your data

Third-party services

The app uses no third-party SDKs. In-app purchases, iCloud, Apple Health and Screen Time are Apple services covered by Apple's Privacy Policy. The public database used by Friends, study groups, chat and Study Hall is also part of Apple's iCloud.

Users in the EU, UK and Switzerland (GDPR)

If you're in the European Economic Area, the United Kingdom or Switzerland, here is what the General Data Protection Regulation (GDPR) and your local laws say you should know.

Who is responsible for your data
The controller is the app's developer, SEER INNOVATION TECHNOLOGY CO., LTD. (Taiwan). Contact: mochipets.care@gmail.com.
What we process and why
Data that stays on your device and in your own iCloud (your pets, focus history, photos, health data, iCloud Sync and Raise with a Friend) is never seen or processed by us. We can only see what is in the public database:
  • Friend cards, photo avatars, study groups, group avatars, group background photos and messages: to provide Friends, study groups and chat, which you turn on yourself (performance of a contract, GDPR Art. 6(1)(b)).
  • Records of Plus gifts: to deliver the gift you bought and let your friend's app confirm it's real (performance of a contract, Art. 6(1)(b)).
  • Invite records: to make sure each account gets the invite reward only once and to give the reward to the person who invited you (performance of a contract, Art. 6(1)(b)).
  • Study Hall windows and stars: to provide Study Hall when you light your window yourself (performance of a contract, Art. 6(1)(b)).
  • Reports, masking offensive words and removing inappropriate content: to keep users safe and prevent abuse (legitimate interests, Art. 6(1)(f)).
  • Steps and Mindful Minutes are health data. They are used only with your consent (Art. 6(1)(a) and Art. 9(2)(a)) and only on your device; they are never sent to us. You can withdraw consent anytime in the Health app.
How long we keep it
Messages are kept for up to 30 days. Friend cards, photo avatars, group and member records, group avatars and group background photos are kept until you turn off Friends, leave or disband the group, or remove the photo. Reports are deleted once we've handled them. Invite records are kept until you ask us to delete them. Gift records are proof of purchase and are kept until you ask us to delete them. Your Study Hall window is kept until you turn off “Light My Window”, and the app deletes stars you sent after 7 days.
Where it is stored
The public database and iCloud are provided by Apple, whose servers may be outside your country or region (for example in the United States). Apple handles these transfers under the safeguards described in its privacy policy. We view data in the public database from Taiwan, for example when handling a report.
Your rights
You can ask for a copy of the data we hold about you, or ask us to correct it, delete it, restrict its use or give it to you in a portable format. You can object to processing based on legitimate interests, and withdraw your consent at any time (this doesn't affect processing before you withdrew it). Email us at the address above with your friend code so we can find your data; we'll reply within one month. You can also do a lot yourself in the app: change your nickname, unsend messages, turn off Friends (which deletes your friend card) or export a backup. You also have the right to complain to the data protection authority where you live.
Other things to know
You don't need to give any personal data to use the app; only the Friends features need a nickname. Masking offensive words and hiding content reported by several people happen automatically and only decide whether content is shown; they have no legal or similarly significant effect on you. If you're under the age your country sets (between 13 and 16), please turn on Friends only with a parent's consent.

Changes to this policy

If this policy changes, we'll update this page and the effective date above. We'll also mention important changes in the app's release notes.
