EISOL LLC (“we”) handles information in Lumisia Animals (Lumisia 生き物図鑑) as follows.

Using the site without registering

Your notebook records (the identifiers of the animals you put in “Like”, “Want to meet” and “Met”, the optional nickname you give an animal in “Like”, and the date and place you met it) are stored in your browser’s local storage. The place you met an animal is only a facility chosen from the list, a prefecture or, outside Japan, a country or region. We do not record photos, positions on a map or free text. To protect where they live, some animals do not record the place they were met in the wild. A nickname is for the animal: please do not enter the real name or contact details of yourself or your family. A file you save with “Export notebook” is also kept on your device. You do not need to enter a name or email address to keep records.

Using the iOS and Android apps

In the apps, your notebook records (the same as above) are stored in the app’s own storage and are not sent to our servers. If you have turned on device backup (iCloud or Google backup), they may be backed up by that feature. The apps have no registration or login, no advertising and no usage measurement. The apps connect to our servers and Google Cloud to receive the encyclopedia content and high-resolution illustrations. For delivery and safe operation, information such as the connecting IP address is recorded in access logs and kept in Cloud Logging for up to 30 days. The “Met” card in the apps is made from the notebook records on the device and the bundled illustrations; the animal, date and place are not sent to our servers to make it. Before opening an external page, sharing, or exporting or importing the notebook, the apps show a check for an adult to answer. If you delete an app, any notebook you have not exported is lost.

“Met” cards

iOS and Android apps

In the apps, the image of a “Met” card is made on the device. When you share a card, the image and a link containing the animal, date and place are passed, after the parent check, to the app you choose. The recipients and anyone who opens the link can see the animal, date and place. Cards and links do not include nicknames. If the receiving app fetches a preview of the link, or a recipient opens the link on the web, the same communication with our servers as in the web version below takes place.

Web version

When you view or make a “Met” card on the web, a URL containing the animal, the date you met it and the place you chose is sent to our servers and used to make the card image and show the page. We do not store card contents as individual records, but the URL and the connecting IP address are recorded in access logs for delivery and kept in Cloud Logging for up to 30 days. People who receive a card or link you share can see the animal, date and place.

Adults who register

Registration and login are for people aged 18 or over. Email addresses and authentication information, and, when you log in with Google, the basic account information Google provides, are handled with Firebase Authentication. We never store passwords in plain text. You can use an existing Lumisia account; shared account information is stored in Firestore.

When you choose “Save notebook”, the animals’ identifiers, the state of “Like” and “Want to meet”, optional nicknames, the dates and places you met them, the time of saving and your own confirmation that you are an adult are saved to a Firestore area for that account only. We use this information to save and restore the notebook and to maintain the service. The notebook is not uploaded automatically. Nicknames are never shown on public pages or in shared links. Registering does not sign you up for promotional or news emails.

About children

Please do not enter a child’s name, email address, date of birth or similar details. There is no account registration for children and no chat input. The confirmation of being an adult is self-declared and does not mean that identity has been verified.

Usage measurement

To improve the site, we record, as daily totals, the number of times pages are opened and the number of “Like”, “Want to meet”, “Met”, “Share”, “Open the facility’s official site” and “Create an adult account” actions. The totals use only the kind of animal, the kind of page, how the visit started (a category such as search, Pinterest or a shared link), the page language, the browser language and the country estimated from the device’s time zone. These records contain no cookies, no IDs for each person or device, no IP addresses, no visited URLs, no nicknames and no dates or places of meeting. So that the same tab is not counted twice, the category of how the visit started and the kinds of actions already counted are kept in browser storage that is cleared when the tab is closed (session storage). Nothing is recorded if your browser has “Do Not Track” or Global Privacy Control turned on.

External services and access information

We use Google Cloud and Firebase to deliver the site, authenticate and store data. These services may process IP addresses, access records and similar information for delivery and security. This site does not show advertising or load tracking tools for advertising. When you open an external link such as a source, that site’s handling of information applies.

Keeping, deleting and contact

You can change or delete records and nicknames from the notebook or an animal’s page. Removing an animal from “Like” also deletes its nickname on that device. You can also erase them by deleting the site data in your browser. Actions on a device alone do not delete what is saved in the cloud. The cloud notebook can be erased with “Delete the cloud notebook” on the adult account page. To delete the account itself or shared Lumisia information, or to check or correct information, please contact us below. Records needed for backups or to keep the service safe may be kept for as long as that purpose requires.
