Sachwert-Tresor: your holdings, offline and encrypted
Most portfolio apps want an account, an email, often an exchange login. They pull prices from the network and store your holdings in the cloud. In the end a stranger's server knows more about your wealth than you would like.
The Sachwert-Tresor does the opposite. A local, encrypted vault for your Bitcoin, gold and silver. Fully offline, no account, no KYC, no cloud. Not a single network request, no trackers, no external scripts. You enter prices yourself.
What it does:
- record Bitcoin, gold and silver (buy, sell, withdrawal)
- net holdings and value, cleanly separated by KYC and noKYC
- export straight into the BTC tax tool format
- encrypted backup, syncable between devices via Syncthing, no cloud
- German and English, switchable in the app
Encrypted with AES-256-GCM, the key derived from your passphrase via PBKDF2-SHA256 with 600,000 iterations. Optional second factor via Aegis. No reset, no backdoor. The code is open source, you do not have to trust, you can check.
