Arkive - Clipboard Manager

From the App Store Source

Arkive is a clipboard manager that remembers everything you copy and helps you find it again, by meaning as well as by keyword. EVERYTHING, SAVED AUTOMATICALLY On your Mac, Arkive watches your clipboard and saves text, links, and images the moment you copy them. On iPhone, send anything to Arkive from the share sheet, including screenshots straight from the preview. FIND WHAT YOU MEANT Search understands context, not just characters. Look for "flight confirmation" and find an email that never uses those words. Copied a screenshot? Arkive reads the text inside it automatically, so it's searchable too. PRIVATE BY DESIGN Every bit of processing, from search to recognizing sensitive content, happens on your device. Arkive has no servers, no analytics, no accounts, and no third-party tracking of any kind. If you turn on sync, your clips move between your own Mac and iPhone through your own private iCloud account. Arkive's developer never has access to it. PASSWORDS AND KEYS, PROTECTED Arkive automatically recognizes when something you copied looks like a password, API key, or other credential, and seals it behind Face ID, Touch ID, or your device passcode, separate from the rest of your history. STAYS OUT OF YOUR WAY Keep a full history or set it to prune automatically after a chosen number of days or items. Pin anything you want to keep for good. Export your whole history as a backup any time. Arkive is free to try in full for 30 days. After that, unlock it once for $2.99, no subscription, ever.
