Words to know
Legal words from the lines above, in plain English.
- cookies
- Small files a website saves on your device so it can recognise you and remember what you did. For example, a cookie keeps you logged in and can also tell an ad company which sites you visited.
- device identifiers
- Codes that single out your phone or computer, used to recognise you across apps and sites. For example, the advertising ID on your phone lets two unrelated apps know they are seeing the same person.
- personal data
- Any information that is about you or can be linked to you, from your name to your phone's ID. For example, your email, your IP address and the list of apps on your phone are all personal data.
- third parties
- Any company or person other than you and the app, such as advertisers, partners or analytics firms. For example, an analytics company that receives a record of every screen you tap is a third party.
- limitation of liability
- A cap on what the company will ever pay you if something goes wrong, often only what you paid in the last year. For example, if a leak of your data costs you thousands, the most you may get back is a month's subscription fee.
- service providers
- Outside companies that handle your data on the app's instructions, such as a cloud host or an email sender. For example, the company that stores the app's files in the cloud sees your data but only does what the app tells it.
- consent
- Your clear agreement to something, given by an action like ticking a box or tapping Accept. For example, a pop-up asking if the app may use your location is asking for consent.
- venue
- The specific court or city where any lawsuit must be filed, which may be far from where you live. For example, a user in Florida may have to travel to a court in San Francisco to sue.
- governing law
- Which country's or state's laws are used to settle any dispute, no matter where you live. For example, a user in Ohio may find the terms are judged under California law.

What does the app collect beyond what it needs to work?
They collect account and service data plus usage, purchase and browsing history, cookies, IP addresses, advertising identifiers, and attributes such as sex, occupation and age.

Not stated in the documents.
Are your chats and uploads used to train AI models, and is that off by default?
Not stated in the documents.
Can employees or contractors read your conversations, and when?
They may inspect, save or disclose account contents for technical faults, legal requests, suspected violations, emergencies or running the service—not as routine chat sampling.
Are you profiled or tracked for advertising?
They analyze usage, purchase and browsing history to customize ads and may give that kind of information to advertisers and group companies.
Do they sell or share your data, and can you opt out?

What rights do they take over what you type and what the AI makes?
Not stated in the documents.
How long do they keep your data after you delete it, and can you delete it in the app?
You can delete a MIXI ID in the way they prescribe, and you request personal-information deletion through their contact form or mail. They do not give a deletion timeline.
Does it build a lasting memory or profile of you, and can you see, edit or turn it off?
Not stated in the documents.
Do they commit to basic security, and have they leaked data?
They describe access controls, employee training, a chief privacy officer and an internal privacy auditor. They do not describe an independent public audit or leak history.
Is there a real age gate, and are teens protected?
Minors must get parental consent to use the account. There is no described age-check beyond that.
Will they tell you when the rules change, and is the policy specific?
The privacy policy lists amendment dates and says important changes will be announced on the website. Terms take effect on your next use after they are displayed.
Can they close your account without warning, and can you get your data out first?
They may forcibly delete an account without prior notice if they think you registered wrongly, broke the rules, or are otherwise inappropriate. Deleted accounts cannot be restored.
If something goes wrong, who pays?
They disclaim most warranties and cap damages at the greater of a monthly fee or 100 yen, except for willful misconduct or gross negligence.
Do subscriptions renew on their own, and can you get a refund?
The MIXI ID account is free in principle. They say they will notify you and get consent before charging any fee.
