Paperweight

Paperweight is a desktop privacy and inbox-auditing app for people who want a clear inventory of companies, newsletters, and sensitive information buried in old mail. It is strongest for privacy-conscious users who prefer local, open-source software and are willing to review actions before they happen. Its broad inbox analysis is valuable, but the lack of automatic rules and data-broker coverage limits its reach.

Overview

Paperweight reconstructs company relationships from sign-up confirmations, receipts, password resets, and security alerts, turning scattered messages into an account and company inventory. It also finds mailing lists and personal details in historical messages, including email addresses, phone numbers, postal addresses, payment cards, IBANs, and national identifiers. That makes it a records-review tool as much as an unsubscribe utility.

Processing and database storage remain on the computer. The maker says its servers do not receive email content or credentials; connections to providers use HTTPS/TLS, and OAuth tokens are encrypted in macOS Keychain or Windows Credential Manager. The MIT license permits inspection and building of the code, an important advantage when software handles private correspondence. Paperweight concentrates on first-party relationships discovered in the inbox, however, and does not remove records held by data brokers.

Key features

Account discovery

The inventory is built from evidence across an inbox rather than from a manually maintained list. This helps users see dormant services and forgotten accounts, although the result depends on what remains in the connected mail history.

Mailing-list cleanup

Mailing lists are grouped for review, with unsubscribe requests supported through one-click headers, email triggers, or sender links. Paperweight prepares actions rather than silently applying them, so it favors deliberate cleanup over unattended maintenance. There are no automatic cleanup rules.

Personal-data review and requests

Detected data categories cover common contact and financial identifiers as well as national identifiers. The app prepares access or deletion requests for approval and does not send them automatically, giving the user control but adding a confirmation step. Requests remain focused on companies represented in the inbox, not broker databases.

Providers, privacy, and MCP

Gmail, Outlook, Apple/iCloud, standard IMAP accounts, and Proton Mail through Proton Bridge are supported. Pro adds MCP through a local stdio server that is disabled by default and can be set to read-only or read-and-write. The agent can access sender and recipient fields, subjects, previews, and app classifications, while full bodies and raw headers are excluded and known personal data is masked by default. That is useful for local automation, but read-and-write mode deserves careful configuration.

Pricing

Free — free, billed Free forever. This includes one email account with full-history sync, the account and company inventory, mailing-list, breach and risk, and personal-data and privacy overviews, plus local curation and community support on GitHub. There is no payment requirement or free trial. The one-account ceiling makes it a sensible starting point for a primary inbox, not a household or multi-inbox solution.

Paperweight Pro — $60 a year, billed yearly through Polar (equivalent to $5 per month). Crypto costs $55 for one year with manual renewal. Pro adds cleanup actions, privacy requests and follow-ups, multiple accounts, MCP access, and email support. It is the practical choice for users who need to act across several inboxes; the annual renewal and paid-only action features are the trade-offs.

Lifetime — $99, paid once. This provides permanent full Pro access and is offered through October 7, 2026; the crypto price is $90. It suits committed users who prefer a single payment, provided the offer is still available when they buy.

Cleanup Pass — $2,530, paid once. There is no subscription or renewal. It includes Free features plus unsubscribe, trash, mark-as-spam, bulk cleanup, privacy requests and follow-ups, multiple accounts, and MCP access, with GitHub community support. Its unusually high one-time price makes sense only for buyers specifically seeking a comprehensive cleanup package without recurring billing.

Platforms

Paperweight runs on Linux, macOS, and Windows. Provider support covers Gmail, Outlook, Apple/iCloud, Proton Mail via Proton Bridge, and standard IMAP accounts.

Who it's for

Choose Paperweight if you want a local account map, privacy-data inventory, and reviewed unsubscribe or deletion workflows in one desktop application. It is particularly well matched to technical users who value MIT-licensed code and local storage. It is a poor fit if you need automatic rules, unattended deletion, or removal from data-broker systems.

Pros and cons

Pros

• Local-first privacy model: email analysis and storage stay on the computer, with no server receiving mail content or credentials.
• Unusually broad discovery: account relationships, mailing lists, risk indicators, and numerous personal-data types are reviewed together.
• Controlled privacy actions: requests are prepared for approval rather than sent automatically.
• Open source and cross-platform: MIT licensing and Linux, macOS, and Windows support widen transparency and device coverage.

Cons

• No automatic cleanup rules: recurring newsletter management still requires user decisions.
• Limited removal scope: inbox-discovered first-party relationships do not cover data brokers.
• Free plan is single-account: multiple inboxes require Pro or Cleanup Pass.
• Cleanup Pass is expensive: its 2530.00 USD one-time price is difficult to justify for ordinary newsletter cleanup.

Alternatives

For a broader category view, see Email Cleanup Software.

Clean Email is the better pick for mobile and web access, a free trial, and paid multi-account cleanup, though its free account is limited to 1,000 messages and omits advanced controls.

Gmail Bulk Unsubscribe & Cleanup Tool suits users wanting a free, MIT-licensed option across desktop, web, or self-hosting, with an optional 8.00 USD one-time setup service.

InboxSweeper is a free, open-source alternative requiring no account or subscription.

Cleanfox is a free Android, iOS, and web choice for inbox cleaning and newsletter unsubscribing.

Unroll.Me is free on Android, iOS, and web, but requires access to commercial emails and uses commercial-email data for measurement products.

Gmail Unsubscriber is a free open-source option for Gmail cleanup.

GMClean is a free, MIT-licensed, self-hosted web option.

Leave Me Alone offers a free four-account tier with unlimited unsubscribes and privacy-oriented controls.

Verdict

Paperweight is a strong choice for one or more inboxes when local processing, open-source transparency, and a detailed account-and-personal-data inventory matter more than automation. Start with Free for a single account, move to Pro for multi-account actions and MCP, or choose Lifetime for a one-off Pro purchase. Look elsewhere for automatic cleanup, a lower-cost bulk-cleaning workflow, or data-broker removal.
