I’m excited to introduce Paperweight, a local-first open-source desktop app I’ve been building to help people understand and reduce their digital footprint.

Your inbox is a paper trail of every company that has ever had your data. Every account you created, every service you tried, every online purchase. It’s all connected to your email. Most people have 100+ accounts they’ve forgotten about, each a potential security, or privacy risk. For me the final push was the Odido data breach in the Netherlands. I hadn’t been a customer for more than 8 years, but all my data was still in their systems.

What it does:

• Account inventory — Maps every company that has ever emailed you, with risks classifications and recommendations for action.
• Bulk unsubscribe — Find and unsubscribe from any marketing and mailing lists (auto RFC 8058 where supported).
• Breach alerts — Alerts when any company you’ve been in contact with has been breached (via HaveIBeenPwned).
• GDPR requests — Generates pre-filled GDPR requests in multiple languages.

Supports Gmail, Outlook, Apple Mail, Proton (via Bridge) and any other email provider via IMAP.

Privacy approach:

Everything runs on your machine. Email content, credentials, and connection details never leave your device. No telemetry, no cloud sync, no analytics. The code is fully open source and auditable on GitHub.

Most alternatives in this space all require your to share your data through their services. Some of them have actually been caught selling your data. Paperweight is the only tool I’m aware of that does this entirely local and is open-source.
