Mailstrom vs Paperweight

Mailstrom has no write-up on Specifiction yet; its figures are above.

Paperweight is a desktop app that scans email to map accounts, mailing lists, and personal data, then helps users clean up and prepare data access or deletion requests. It builds a company inventory from messages such as receipts, sign-up confirmations, password resets, and security alerts. The app identifies mailing lists for unsubscribe requests and detects personal details in past messages, including addresses, payment cards, IBANs, and national identifiers. It supports Gmail, Outlook, Apple/iCloud, standard IMAP accounts, and Proton Mail through Proton Bridge. Analysis and database storage happen locally; the maker says its servers do not receive email content or credentials. Published under the MIT license, the app lets users inspect or build its code. Free includes one email account with full-history sync and overview features. Pro costs $60 a year, billed yearly, and adds cleanup actions, multiple accounts, privacy requests, and MCP access. Requests are prepared for user review, not sent automatically. Paperweight focuses on relationships found in the inbox and does not remove data-broker records.
