Habeas by David Marín Carreño

Your data is yours. Getting it out isn't. Many services — supermarkets, utilities, banks — make bulk export of your own receipts, invoices and transactions practically impossible: no API, no email export, and a web interface guarded by anti-bot walls.

Habeas is a free, open-source (AGPL-3.0) extension that extracts your own data from those services — entirely inside your own, already-authenticated browser session.

• In your own session. It runs after you log in yourself (MFA included). It never stores, transmits, or autofills your passwords, and there is no server-side login and no background scraping while you're away.
• Local-first. Your documents and your session never leave your browser unless you pick a destination. The project runs no servers and never receives your data.
• You choose where it goes: a download, a local folder, your own Google Drive (only files Habeas creates — it can't see your other files) or Dropbox, an HTTP endpoint you configure (e.g. a personal-finance app you use), or a WebDAV / S3-compatible store you control.
• Declarative, auditable sources. Each service is described by data, not code — open to community contributions and reviewed in the open. No remotely-hosted code, ever.
• No trackers. No analytics, no telemetry, self-hosted fonts.

Habeas exercises your GDPR Art. 20 right to data portability, on your own data, with software you run. Each service's Terms may restrict automated access — complying with them is your responsibility.
