Lantern is made by AKARI Inc. It keeps your tasks, notes, calendar, contacts and meeting recordings together. This page covers the Lantern web app, the Lantern apps for iPhone and Mac, and this website.

Business and Personal

Lantern comes two ways, and who's in charge of your information depends on which you use. Either way, your information is kept on the server you sign in to and nowhere else, apart from the services listed below.

• Lantern Business: your organization has a Lantern server of its own. AKARI may run it for them, or they may run it themselves. Your organization decides who gets an account and is in charge of the information on its server. When AKARI runs the server, we look after it on your organization's behalf and use your information only to run Lantern for you.
• Lantern Personal: your account is on a server AKARI runs for many people. Each person's information is kept apart, and nobody else on the server can see yours. AKARI is in charge of your information and uses it only to run Lantern for you.

What Lantern keeps

• Your account: your name and email address, and how you sign in (your password is stored only as a secure hash; passkeys and authenticator apps are optional), and for each device you're signed in on, its IP address and browser or app version, to keep your account secure.
• Your work: the tasks, notes, calendar events, scorecards and categories you add.
• Contacts: the people you add, with the details you give them, such as email addresses, phone numbers, company, birthday and how they're related to you.
• Meeting recordings: audio from your microphone, only while you're recording a meeting.
• Microsoft 365, if you connect it: your Outlook calendar (read and updated), your Microsoft To Do tasks (read and updated), emails you flag in Outlook (read), your OneNote notebooks (read), and your Teams meetings' recordings and transcripts (read).
• The AKARI Portal, if you connect it: the portal tasks assigned to you, and your changes to them.

The iPhone and Mac apps

• They keep a copy of your Lantern on the device so it works offline, and they talk only to the Lantern server you choose.
• They use the microphone only when you press Record, and send notifications only if you turn reminders on.
• They contain no analytics, advertising or tracking code.

What we don't do

We don't sell your information, show you ads, or track you across other apps and websites. Lantern's cookies only keep you signed in and remember your theme and time zone; there are no advertising or tracking cookies.

Who else sees it

• Microsoft, when you connect Microsoft 365, under Microsoft's own terms.
• AI tools you connect. Lantern can be connected to AI assistants such as Claude. They see only what you allow when you connect them, and you can disconnect them at any time in Settings.
• Backup storage. Each server copies its data to an encrypted backup with a storage provider: AKARI's for Personal, and for Business the one your organization chooses.
• Network and email providers that carry Lantern's traffic and send its emails, such as invitations and password resets.
• Transcription. Lantern doesn't transcribe or summarize recordings with an outside service yet. Before it does, we'll update this page to name the service and what it receives.

Keeping and deleting

Your information stays on the server until it's deleted. Things you delete go to Trash first. Deleting an account deletes everything of that person's from the server:

• Personal: email us at [email protected] and we'll delete your account.
• Business: your organization's Lantern admin can remove your account, or email us and we'll do it, or pass your request to the admin if AKARI doesn't run your organization's server.

Backups can keep older copies for a time after that, until the server's backup storage clears them.

Keeping it safe

The servers AKARI runs are only reachable over encrypted connections (HTTPS), and the apps won't connect to any other server without it. Sign-in supports passkeys and authenticator apps, and backups are encrypted.

This website

If you leave your email address on this website, we use it only to tell you when Lantern is available. Ask us and we'll remove it.

Children

Lantern isn't meant for children under 13.

Changes

If we change this page, we'll update the date at the top. For a change to how your information is used, we'll tell you in Lantern first.
