Privacy Policy

Effective date: 2026-04-21

HCZN Writer is a Chrome extension used to record web workflows, capture screenshots, and export structured documentation. The product is built around a local-first design: screenshots, steps, annotations, and editor content stay on your device unless license verification is required.

What we collect

• The license code you enter when activating Pro.
• An anonymous device fingerprint used to enforce device binding limits.
• Minimal license-service logs such as activation, verification, unbind timestamps, and hashed IP identifiers.

What we do not collect

• We do not collect your screenshot content.
• We do not collect the actual workflow steps you record.
• We do not collect your Chrome account, cookies, login sessions, or payment card details.
• We do not collect browsing history for ads, profiling, or resale.

Where data is stored

Screenshots, step records, and editor content are stored locally in chrome.storage.local. License-related minimum data is processed through Cloudflare Workers and D1 only for license validation and support operations.

Third-party services

We use Cloudflare Workers and Cloudflare D1 for the license service. Payments for Pro may be processed by providers such as Paddle or LemonSqueezy, which handle transaction data under their own policies.

How we use the information

• To verify whether a license code is valid.
• To track device bindings and prevent abusive multi-device use.
• To process refunds, revocations, and basic fraud control.
• To diagnose license service issues.

Retention

Local browser data remains under your control and can be removed by uninstalling the extension or clearing local storage. Server-side license and log data is retained only as needed for support, billing, and abuse prevention.

Your rights

• You can stop using the extension and delete local data at any time.
• You can request device unbinding or license revocation support.
• You can contact us to request access to or deletion of order and license-related personal data where applicable.

Children's privacy

This product is not intended for children under 13.
