Privacy Policy

At KanbanTab, accessible from kanbantab.com, our mobile applications, and our browser extensions (Chrome, Edge, Firefox), one of our main priorities is the privacy of our users. This Privacy Policy document contains types of information that is collected and recorded by KanbanTab and how we use it.

1. The Two Modes of Operation

KanbanTab operates in two distinct modes, which affects how your data is handled across our website, Android application, and browser extensions:

A. Guest Mode (Unregistered)

If you use KanbanTab without signing in:

• Local Storage Only: Your boards, items, and settings are stored locally on your device using IndexedDB or extension storage.
• No Server Transmission: Your content data is never sent to our servers. It exists solely on your device.
• Data Loss Risk: If you clear your browser data, clear the mobile app cache, or remove the extension, this data will be permanently lost. We cannot recover it.

B. Account Mode (Registered)

If you sign in with Google:

• Cloud Sync: Your data is securely transmitted to our servers to allow synchronization across devices (Web, Mobile, and Extensions).
• Encryption: Data is encrypted in transit (TLS/SSL) and at rest.
• End-to-End Encryption (Optional): If you enable E2EE, your data is encrypted on your device before it reaches us. We store only the encrypted binary blob and have zero knowledge of the contents.

2. Information We Collect & Permissions

Personal Information

When you register for an account, we collect the following information via Google OAuth:

• Name: To display on your profile.
• Email Address: To identify your account and send critical transaction emails.
• Google ID: A unique identifier to link your account.

Browser Extension Permissions

Our extensions (Chrome, Edge, Firefox) request only the minimum permissions required to function:

• Storage: To save your boards and settings locally.
• Identity (Optional): To facilitate Google Sign-In for Account Mode.
• Note: Our extensions do not read your browsing history, access your data on other websites, or track your activity across the web.

Mobile Device Permissions

The KanbanTab Android application does not request or require access to your camera, microphone, contacts, or precise GPS location.

Payment Information

Premium subscriptions are managed via our web platform. Payment processing is handled by Stripe. We do not collect or store your credit card information within the mobile application or browser extensions.

3. Data Retention and Deletion (Google Play Compliance)

We retain your personal information only for as long as is necessary for the purposes set out in this Privacy Policy.

• Account Deletion: You may delete your account and all associated data at any time. You can do this by:
  • Logging into your account portal at https://account.kanbantab.com/
  • Emailing us at [email protected].
• What is Deleted: Upon account deletion, the following data is permanently removed from our active databases:
  • Personal identifiers (Name, Email Address, Google ID).
  • User-generated content (Kanban Boards, Stacks, Items, Notes, and Routines).
  • Application settings and customization.
• What is Kept: We only retain data that we are legally required to keep, such as anonymized transaction logs for tax and accounting purposes (via Stripe). We do not keep your personal task data after deletion.
• Retention Period for Backups: Deleted data may remain in our secure, encrypted backups for a maximum of 30 days for disaster recovery purposes before being permanently overwritten.

4. End-to-End Encryption (E2EE)

We offer an optional End-to-End Encryption feature. When enabled, your data is encrypted using AES-256 on your device before being synced. We do not store your passphrase; if you lose it, we cannot recover your data.

5. Third-Party Privacy Policies

• Google: Used for Authentication. Google Privacy Policy
• Stripe: Used for Payments (Web). Stripe Privacy Policy

6. Local Data Storage

KanbanTab is a "Local-First" application. This means we use device storage technologies (specifically IndexedDB and chrome.storage) to function. This enables the app to load instantly and work offline. We do not use cookies for third-party tracking or advertising.

7. Children's Information

We do not knowingly collect any Personal Identifiable Information from children under the age of 13. If you think that your child provided this kind of information on our platform, we strongly encourage you to contact us immediately.

8. Consent

By using our website, mobile application, or browser extensions, you hereby consent to our Privacy Policy and agree to its terms.
