I built a small browser tool called Document Copy Planner to help people figure out how many copies of their important documents to keep, in what format, and where, all fully offline.

Key features:

Supports passports, IDs, contracts, receipts, tickets, and more

Generates a primary, backup, and emergency copy plan

Downloadable PDF or printable checklist

Runs entirely in the browser — no accounts, no uploads, no tracking

The motivation: most people store sensitive documents in cloud apps or email, which increases exposure risk. This tool gives a simple, actionable plan to keep copies safe without relying on servers or third parties.

You can try it here: proofpocket.com/doc-copy-planner

I’m curious to hear feedback from the HN community:

Does this approach make sense for offline document planning?

Anything I could improve in the workflow or UX?

Any edge cases I’m missing for security or usability?

Thanks for checking it out!
