What is it?
Paperweight is a desktop app that reads your email to build an inventory of the accounts, vendors and services tied to your address. Most people have many forgotten sign-ups, and each one is a security and privacy exposure. Paperweight shows where your data likely lives so you can review it in one place.
It connects to Gmail, Microsoft, Apple and custom IMAP accounts, with presets for providers such as Fastmail, Yahoo Mail and Proton Mail via Bridge. It finds marketing and bulk mailing lists to unsubscribe from, alerts you when companies you use appear in breaches via haveibeenpwned.com, and can generate GDPR deletion requests. Emails and settings are stored on your machine, and the project states that no data is sent to external servers.
Free features cover one email account, account discovery and local curation. Paid plans add unsubscribe, trash and bulk cleanup actions, multiple accounts and MCP access. Building from source requires your own OAuth credentials for Google and Microsoft.
