Can the address file be password-protected (encrypted)?
Not yet. Password protection is not something that can be grafted onto an existing design – it wouldn’t be done right that way. I originally intended to add this to PhoneDeck from the start, but then I realized I already had too many applications that encrypt data, each with its own password. I decided it’s overall a better idea, instead, to use some sort of disk encryption software, such as PGP Disk (freeware versions exist), ScramDisk (free, but somewhat unwieldy) or BestCrypt (commercial). That way, you are assured of reliable encryption, and you can protect all your sensitive data regardless of whether the particular application supports encryption. However, encryption will be available in version 2.0 of PhoneDeck.
