Privacy Policy

We respect your data sovereignty. Learn how we collect, use, and safeguard your information.

Last Updated: November 2025

Overview

Your privacy is fundamental to the ZenToDo philosophy. We believe your workspace should be a sanctuary, free from surveillance and data exploitation. This policy outlines exactly what we collect, why, and how we protect it.

Commitment to Privacy

We are committed to transparency and your control over personal data. This policy complies with GDPR, CCPA, and other global privacy regulations. We do not sell your data.

Data Collection

We collect only what is necessary to provide our services:

Identity Data

  • Email address
  • Display name
  • Profile picture
  • Authentication provider ID

Workspace Data

  • Task titles & descriptions
  • Completion timestamps
  • Focus session duration
  • Quiz & Poll results

Telemetry & Performance

  • Device type & OS
  • Browser version
  • Crash reports
  • Page load metrics

Security Protocols

Encryption Standards

All data is encrypted in transit using TLS 1.2+ and at rest using AES-256 encryption. Our database infrastructure is hosted in secure, SOC2 compliant data centers.

Data Usage

We operate on a principle of data minimization. Your data is used strictly for:

Service Delivery

Syncing tasks across your devices.

AI Analysis

Optional processing for productivity insights (Groq/Llama).

Account Safety

Fraud detection and authentication.

Communications

Transactional emails (password reset, etc).

* Note: When using AI features, data is fleetingly processed by our AI partners (Groq, Moonshot AI, Google) to generate insights. Your data is NOT used to train their public models.

Integrations & Privacy

ZenToDo connects with a small set of trusted third-party services to power calendar sync, notifications, whiteboarding, payments, and AI features. We design these integrations with a strict "least access" philosophy and never sell or share your data for advertising.

Google Calendar

When you connect Google Calendar, we request the minimum scope needed to read and create events for your primary calendar. OAuth tokens are stored in your browser session and our servers never see your Google password. You can revoke access at any time from Google Account > Security.

Slack

Slack is used to deliver optional workspace notifications (for example when tasks are completed). Notifications are sent via a secure incoming webhook URL. We do not read your Slack messages or channels beyond the target destination you configure, and you can revoke access from your Slack workspace at any time.

Notion

The Notion integration uses OAuth 2.0. Access tokens are stored on our servers in a restricted Supabase table and are not exposed to other users or client-side code. We only access the workspaces, databases, and pages you explicitly share with ZenToDo, and you can disconnect at any time from either Notion or your ZenToDo settings.

Excalidraw & Whiteboard

Our visual whiteboard is powered by the open-source Excalidraw canvas and runs entirely in your browser. Whiteboard content is stored in ZenToDo only when you choose to save it; we do not send your drawings to any Excalidraw-hosted servers.

Payments & Subscriptions

Paid plans are processed through Cashfree Payments in India. We do not store full card numbers or banking credentials on our servers; those are handled by Cashfree as the payment gateway. We store only subscription metadata (plan, billing period, status) and minimal transaction references needed for invoicing and fraud prevention.

Optional AI features may send snippets of your content to our AI providers (such as Groq, Moonshot, or Google) strictly for the purpose of generating responses. This data is not used to train public models, and we retain only what is necessary for usage accounting and abuse prevention.
