Privacy Policy

What Kirei Is

Kirei is an email client that connects to your Gmail account with Google OAuth so you can read, organize, search, snooze, reply to, send, and manage email from Kirei. Kirei is not an advertising product, analytics broker, or data resale service.

Your email can include conversations, travel plans, purchases, financial notices, calendar invitations, and personal details. Kirei treats that data as private user content.

Google Data Kirei Accesses

Kirei uses Google’s official OAuth system. Kirei never sees or stores your Google password. You grant specific permissions, and you can revoke them at any time in your Google account settings.

• •Google profile data — your Google account ID, name, email address, and profile picture so Kirei can create and display your account in the app.
• •Gmail message data — message headers, sender/recipient data, subject lines, bodies, snippets, attachments metadata, thread metadata, and Gmail settings needed to show your inbox and message detail views.
• •Gmail labels and state — labels such as inbox, starred, sent, trash, drafts, and user labels so Kirei can support actions such as done/archive, pin, search, and bundle organization.
• •Send access — draft, reply, forward, and send email only when you choose to compose or send a message in Kirei.
• •Calendar event data — calendar invitation details and attendee response status so Kirei can show event cards and let you RSVP to invitations from the app.

How Kirei Uses Google Data

Kirei uses Google user data only to provide and improve visible, user-facing email features in Kirei:

• •Display Gmail inboxes, threads, messages, labels, and search results.
• •Organize messages into bundles and preserve multi-account context.
• •Archive, pin, label, snooze, and otherwise manage threads when you take an action.
• •Compose, reply, forward, and send emails you explicitly choose to send.
• •Extract useful highlights such as flights, packages, reservations, and calendar invitations.
• •Generate optional smart replies, summaries, categorization, and snooze suggestions.

Kirei does not use Google user data for advertising, retargeting, building advertising profiles, selling data, or training Kirei-owned AI models.

What Kirei Stores

Gmail remains the source of truth for email. Kirei stores OAuth tokens and app-specific state needed to operate the product, including linked account records, snooze schedules, reminders, bundle preferences, user settings, cached message highlights, push notification state, and local/offline cache data on your device.

Kirei stores only what is needed for the product features you use and to avoid repeatedly processing the same messages.

Service Providers And Data Sharing

Kirei does not sell Google user data and does not share it with third parties for advertising, analytics brokerage, or unrelated purposes. Kirei may process data with service providers that are necessary to run the app, such as hosting, database, push notification, email API, and AI infrastructure providers.

When AI features run, relevant message content may be sent to an AI provider solely to perform the requested Kirei feature, such as categorization, highlights extraction, smart reply, or smart snooze. Kirei does not authorize service providers to use Google user data for advertising or model training.

Google API Limited Use

Kirei’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Kirei requests only the Google permissions needed for the email and calendar features described in this policy. If Kirei changes how it accesses or uses Google user data, this policy will be updated and users will be asked to consent where required.

Security

Kirei protects user data with HTTPS in transit, managed cloud infrastructure, access controls, and secure token storage. OAuth tokens are treated as sensitive credentials. Local app sessions are stored using platform secure storage where available.

Your Choices And Deletion

You can disconnect your Gmail account from Kirei at any time. You can also revoke Kirei’s Google access in your Google account security settings. If you request account deletion, Kirei will delete app-stored account data associated with your Kirei account, including app settings, cached highlights, snooze entries, reminders, and stored tokens, unless retention is required for security, abuse prevention, or legal reasons.
