Hey HN,Did you know you can download all your emails (and attachments) from GMail into a .mbox format using Google Takeout (https://takeout.google.com)?I did this and for the longest time my .mbox backup just sat around. I built a web app that can take an .mbox file and load it into a UI that looks like GMail: threaded conversations, original labels and categories, contacts, attachments, and full-text search.The mail never leaves your machine: the upload and parsing happens in a Web Worker in your own browser, and the archive is stored in browser storage on your device. Close the tab and it s wiped.There s no account required to try it out, and if you still don t trust it there s a built-in demo mailbox — no file needed.Try it out at https://mboxreader.com. Let me know if you have any questions or any constructive feedback. Thanks in advance!Pre-emptive FAQs:1. If no account required why is there sign up? : I m curious if there is a power user use case that needs support for larger backups and advanced features. But again, there s no need to sign up to try out the app. 2. Why make it a web app instead of something I can run locally and privately? : There s less friction to try it out as a web app and local setups don t eliminate privacy concerns either.
