Can I use keyboard shortcuts?

Privacy Policy

Introduction

Spoold ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you use our website at spoold.com (the "Service").

Our core principle: Your data stays on your device. All processing happens client-side in your browser. We don't store, transmit, or have access to the content you paste into our tools.

Information We Don't Collect

Unlike many web services, we deliberately minimize data collection:

No accounts required: You can use all tools without registration
No content storage: JSON, HTML, JWT tokens, or any data you paste is processed entirely in your browser
No tracking cookies: We don't use tracking cookies or fingerprinting
No personal data: We don't collect names, emails, or other personal information

Information We May Collect

Local Storage

We use your browser's local storage to save:

Theme preference (light/dark)
Recent tool usage history (stored locally, expires after 90 days)
Saved items you explicitly choose to save

This data never leaves your browser and can be cleared at any time through your browser settings.

Analytics (Minimal)

We may use privacy-focused analytics to understand how our tools are used. This includes:

Page views and tool usage counts (aggregated, anonymous)
Browser type and screen size (for compatibility)
Referral source

We do not use this data to identify individual users.

Sharing Feature

When you explicitly choose to share content via a link:

Content is encrypted client-side before upload using AES-GCM encryption
We cannot read the content as we never have access to the encryption key
Shared links expire after a set time period
You can set additional protection like passwords or burn-after-read
