Privacy Policy

Last updated: March 22, 2026

1. Overview

Etch ("we", "our") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights. Etch is a local-first app — your todos and memos are stored on your device by default.

2. Data We Collect

Account information

When you sign in with Google, we receive your email address and Google account ID. This is used solely for authentication and subscription management.

App data (Pro plan only)

If you enable cloud sync, your todos, memos, and categories are stored in Supabase (our cloud database provider). This data is tied to your account and protected by Row Level Security — only you can access it.

Payment information

Payments are processed by Polar.sh. We do not store your credit card details. We receive confirmation of subscription status (plan, renewal date) via webhook.

3. How We Use Your Data

  • To authenticate you and manage your subscription
  • To sync your app data across devices (Pro plan)
  • To enforce plan limits (Free plan)
  • To send transactional emails (billing receipts, account notices)

We do not sell your data, serve ads, or share your data with third parties except as described below.

5. Data Storage & Security

Your app data on-device is stored in a local SQLite database. Authentication tokens are encrypted using the operating system's secure storage (Windows Credential Manager). Cloud data is protected by Supabase Row Level Security policies.

6. Data Retention

Your cloud data is retained as long as your account is active. If you delete your account, your cloud data will be permanently deleted within 30 days. Local data on your device is not affected by account deletion.

7. Your Rights

You may request access to, correction of, or deletion of your personal data at any time by contacting us. You can also export your local data directly from the App.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes via email or in-app notice. Continued use of the App after changes constitutes acceptance.
