Create deliberate, password-authenticated AES-256 encrypted backups. Save them to any local folder, USB drive, or trusted storage provider you choose.
Generous free tiers that remain permanently useful, paired with transparent one-time lifetime Pro upgrades. Zero predatory subscriptions or hidden paywalls.
Everything you need to know about our local-first software and data practices.
Yes. All core functionalities—including recording service, tracking inventory, viewing history, scanning barcodes, on-device OCR, and generating backups—function completely offline without an active internet connection.
You can create an encrypted backup in the app's settings using a password of your choice. Transfer the encrypted file to your new device via USB, cloud storage, or local network, and restore it inside the app using your password.
No. For maximum security and privacy, your backup is authenticated and encrypted locally using industry-standard cryptographic algorithms. We do not possess any decryption keys or backdoors. Please store your backup passwords safely.
ServiceVault is completely ad-free and tracking-free. AbodeLedger operates under the same strict local-first privacy standard and includes zero analytics telemetry on your inventory items.
