DocuStash - Smart renewal reminders + AES-256 encrypted document vault

I built this for myself. First: I was mid-renovation on my house when it occurred to me that I had no idea who my home insurer was or whether the policy was still active. I spent far too long trawling through emails before I found it - still valid, months to run. Relief, but also.... that was completely unnecaessary. Second: Not too long ago, I only realised my MOT had expired when I had a flat tire at home and the AA said they could not attend because the MOT on the car had run out!! Third - and this one has been a slow grind - every time I need to call my broadband provider or a utility company, I spend about ten minutes or so just finding my account number. Hunting through old letters, trying to remember portal logins. It’s a small thing, but it happens constantly. So as an engineer I eventually said, "why don't I just build my own personal solution"?! But when it came to the document vault, I had one hard requirement: nothing uploads until it's encrypted on the device. Not "encrypted in transit" - client-side encrypted, with the key living on your device and never touching a server. If someone compromises Firebase tomorrow, they get ciphertext. The trade-off is – if you forget your passphrase we cannot recover your data. But that is the point... If we cannot get in, neither can anyone else - that’s the design. DocuStash is free to start with (up to three items). Additional features are subscription funded. If you've ever had that "wait, am I even insured right now?" moment - this is for you. Happy to answer any questions.
