Privacy policy

This page is a translation of the Japanese original. If they differ, the Japanese version prevails.

SANGGI LEE (an individual; "we") runs Machiwa, a service for local hobby circles and events (the iOS and Android apps and the web version at https://machiwa.web.app; the "Service"). This policy explains how we handle personal information under Japan's Act on the Protection of Personal Information and other applicable laws.

1. Who we are

2. What we collect

Account

The Google or Apple account identifier and email address you sign in with (a relay address if you chose Apple's Hide My Email), or, on the web, the email address you sign in with by link. For people who moved over from the old test version, a value derived from their phone number that cannot be turned back into it (a hash) and the country code. Your email address is never shown to other users.

Profile

Display name (taken from your Google or Apple account at first), profile photo, introduction and activity area (a place name). We do not ask for your age, gender or date of birth.

Location (optional)

Circles and events

Circles and events you create; the introduction and answers in your requests to join a circle; member and staff roles; event sign-ups, waitlist places, cancellations and attendance; QR ticket check-in times; seats; poll answers; records of random draws and event games (roles, votes, drawings and so on); saved circles and events. Answers to questions a host adds to an event sign-up (for example nationality, gender or a social media account) and the "paid" mark a host records. Names a host types into a team split for people who do not use the app. Event fees are paid between the people involved, outside the Service; we never receive payment details.

Posts and messages

Board posts, comments and likes; stories; event photos; circle chats (text and photos); DMs (between an event's host or staff and an attendee, and trade DMs about used items; text and photos); photos and short clips in Today's log (sound is not kept and clips are cut to at most 4 seconds) and their captions; the daily vlog made from the log; used-item listings (photos, description, price, status) and trade ratings; anything you send through the feedback form.

Safety records

Reports (who reported, what was reported, the reason and an excerpt of the content), blocks and restrictions.

Notifications

Your push notification token, device type (iOS or Android), the app's language (so notifications arrive in it), notification settings (on or off per type, muted chats, quiet hours and time zone) and in-app notices.

Usage and technical data

The kind and time of actions such as opening the app, viewing a screen or posting, and the app version (recorded with your account to improve quality and investigate problems). Server access logs: IP address, browser and device type, the URL requested (including ad measurement parameters), the referring page and the time. The Service contains no advertising or behavioral analytics tools.

3. Why we use it

We do not use personal information beyond these purposes. We do not use it for advertising and we do not sell it.

4. What other users can see

5. Service providers and processing outside Japan

We use the following companies' services to process and store information. They handle personal data on our behalf, and we supervise them appropriately. Except where the law requires it, we do not give personal information to third parties without your consent.

When you press the translate button, the event or circle description or the chat message on screen is sent to Google Cloud Translation. Translations are only kept in memory for a short time, not stored.

The database, photos and videos and the servers are in Japan (Tokyo). Some processing, such as sign-in, push notifications, translation (processed in the USA) and access logs, may take place outside Japan, for example in the USA, by Google or Apple. We have checked the USA's personal information protection system in the survey on foreign systems published by Japan's Personal Information Protection Commission.

6. How long we keep it

7. Deleting your account

You can delete your account at any time in the app or on the web: My → Settings → Delete account. See Delete your account and data for the steps and what is deleted and kept.

You can also keep your account and delete posts, messages (unsend), listings, Today's log entries and so on from each screen.

8. Requests for access, correction or suspension

You can ask us to tell you the purposes of use of your retained personal data, to disclose it (including records of provision to third parties), to correct, add to or delete it, to stop using or erase it, or to stop providing it to third parties. Write to dvdsang2@gmail.com from the email address you registered. After confirming it is you, we will respond without delay as the law requires. There is no fee. Complaints and questions about how we handle personal information go to the same address.

9. Age

The Service is for people aged 18 or over. If we learn that information belongs to someone under 18, we will suspend the account and delete the information.

10. Security measures

11. Browser storage and data sent to other services

The web version keeps your sign-in state, language and whether you have dismissed notices in browser storage (such as local storage). We do not use cookies for advertising or behavioral analytics.

On the web version, to show pages and sign you in, your browser sends your IP address, browser type and the URL of the page you are on to Google services (Firebase Authentication, Cloud Storage for Firebase and Google Fonts).

12. Changes

We may change this policy when laws change or features are added. We will announce important changes in the Service or on this page. A revised policy applies from the time it is posted here.
