The life admin app that never phones home. AdminShark reminds you before your car, insurance, warranties and subscriptions are due, and keeps documents, IDs and a private diary in an encrypted vault only you can open. No account, no cloud, no server holding your data. New: Contact tags. A QR sticker for your car, keys or front door. Whoever scans it can message you, and you can reply, with no phone numbers revealed. End to end encrypted; the only server just relays what it cannot read.
