Privacy Policy - KALE for Android

This Privacy Policy explains how K.A.L.E. (“K.A.L.E.”, “we”, “us”, “our”) collects, uses, and shares information when you use the K.A.L.E. Android app (the “App”).

Contact: kale.ai.email@gmail.com

1) Summary (What this app does)

K.A.L.E. connects to your Google account to help you manage and automate email workflows. Depending on the features you enable, the App may:

Sync email metadata and content from Gmail.
Draft, send, label, move, trash, or delete emails based on rules you configure.
Extract calendar events from emails and create/update/delete events in Google Calendar.
Provide AI-assisted summaries, categorization, or drafting via a Google Cloud backend.
Send you notifications and perform background processing so automations run reliably.

2) Definitions

“Google User Data”: data obtained from Google APIs (e.g., Gmail/Calendar data) and/or your Google account.
“Content”: the body of an email, attachments, and message parts.
“Metadata”: headers and non-body information (e.g., From/To/Cc/Bcc, subject, timestamps, labels, message IDs).
“Local storage”: data stored on your device (e.g., app database, cache, downloaded attachments).

3) Information we collect

We collect information in the following categories. Some data is required to provide core functionality; other data is optional and depends on the features you enable.

3.1 Account and authentication information

Google account email address and basic profile info (as provided by Google Sign-In).
Firebase Authentication identifiers and tokens (e.g., Firebase UID, auth tokens) used to authenticate requests to our backend services.

3.2 Gmail data (Google Gmail API)

If you connect Gmail, the App may access and process:

Email metadata: sender/recipient fields, subject lines, timestamps, labels, thread IDs, message IDs.
Email content: email body and message parts needed to display messages, generate summaries, perform search, apply rules, and draft replies.
Attachments: when you choose to download attachments, the App retrieves attachment data from Gmail and stores it on your device.

Important: K.A.L.E. accesses Gmail only to provide the features you enable (sync, display, search, automation rules to include sending, and optional AI features). We do not sell Gmail data and we do not use it for advertising and most importantly - we cannot view it nor do we store it on our servers.

3.3 Calendar data (Google Calendar API)

If you enable calendar features, the App may access and process:

Calendar list information (e.g., calendar name/ID and whether it is primary).
Calendar events created or modified by your configured automations (e.g., event titles, times, attendees if you include them, and related event metadata).

3.4 Contacts derived from email (in-app contacts list)

K.A.L.E. may derive and store a contacts list from email headers (e.g., frequent senders/recipients) to support automation and UI features. This is based on your Gmail data (not your device address book), unless explicitly stated in the App.

3.5 App settings and user-provided content

App preferences and automation settings.
Custom prompts/instructions you configure for AI features.
Rules, filters, signatures, and similar settings you create within the App.

3.6 Device, diagnostics, and usage data (Firebase services)

We use Google Firebase services such as Firebase Analytics, Firebase Cloud Messaging (FCM), Firebase Authentication, and Firebase Firestore. These services may collect:

Device information (model, OS version, language, region).
App usage information (e.g., basic analytics and engagement signals).
FCM token and notification delivery metadata to deliver notifications.
Diagnostic information necessary to operate and secure the App.

Note: We do not use advertising identifiers for behavioral advertising in the App.

3.7 Subscription and billing information (Google Play Billing)

Google Play processes your payment information. We do not receive your full payment card details.
The App and our backend may process purchase-related data needed to validate entitlement (e.g., product ID, purchase token, package name, and subscription status).
We may store your subscription plan status (e.g., “premium”) associated with your Firebase UID to enable premium features.

4) Permissions and access (Android)

Depending on your device and features you use, the App may request or use:

Internet/network access: to connect to Google services and our backend.
Notifications: to show email/automation alerts.
Background/foreground processing: to run automation tasks reliably.
Storage/media access: to save downloaded attachments to your device (e.g., Downloads/Documents/Pictures) using Android storage frameworks.

5) How we use your information

Provide core email and automation functionality.
Provide calendar features you enable.
Provide AI-assisted features (summaries, drafting, extraction, categorization).
Deliver notifications and background processing.
Maintain app security, prevent abuse, and provide support.
Verify subscriptions and enforce premium entitlements.

6) AI processing and automated decision-making

6.1 AI processing

By subscribing and installing this app you enable AI features. The App may send selected email content/metadata and your configured prompts to our backend in order to generate AI outputs. Our backend server serves only to send this data to Gmail and Gemini servers and will not store the information on our servers.

6.2 Where AI processing happens

AI requests are sent over encrypted connections (TLS/HTTPS) to our Google Cloud backend services (Cloud Run and Cloud Functions) in the United States (region: us-central1).

6.3 Your controls

You control what automations run and can change, pause, or disable rules at any time.

6.4 No human review by default

We do not have humans read your Gmail content. It is sent via end-to-end encryption. If you contact support, avoid sending sensitive content.

7) How and when we share information

We do not sell your personal information. We share info with processors like Google Gmail API, Firebase, and Google Play Billing only to operate the App.

8) Google API Services User Data Policy (Limited Use)

K.A.L.E.’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including Limited Use requirements. We do not sell data or use it for advertising.

9) Data storage and retention

We minimize backend storage. On-device data can be cleared via "Clear all email data" or "Sign Out & Delete All Email Data." Backend data is typically processed and discarded within minutes.

10) Security

We use encryption in transit (TLS/HTTPS) to protect information. No method is 100% secure.

11) Your choices, controls, and rights

You can revoke Google access via your Google account settings. You can control notifications via Android settings.

12) Account deletion (in-app) and data deletion

Delete your account via Settings → Maintenance → Delete Account. This removes auth records and local data. Subscriptions must be cancelled via the Google Play Store.

13) Children’s privacy

The App is not directed to children under 13.

14) International data transfers

Data may be processed in the U.S. and other countries where Google operates.

15) Do Not Track signals

We do not respond to Do Not Track signals at this time.

16) Changes to this Privacy Policy

We may update this policy; the "Last updated" date will reflect changes. Continued use means acceptance.
