About

Stash

Stash is the fastest way to save a link or a bit of text on one device and pick it up on another. Built like all my apps: private by design, no accounts, no tracking. Save it, find it later, get on with your day. Like everything I make, Stash starts from a simple foundation: your data is yours. There's no account to create, no server of mine holding your stuff, and no tracking of any kind. Everything syncs through your own iCloud and stays there. I built Stash because I kept finding links on my phone that I wanted to view later on my Mac, and vice versa. Like many people, I would message them to myself. That was not an elegant or user-friendly solution. I just wanted a box to toss things into that would sync everywhere. Everything else I tried wanted to be a read-it-later service, had a different goal in mind, wanted me to create an account, had unnecessary "social" features, or had questionable privacy. FEATURES: * No account, no tracking, no subscription * Save links and text from the share sheet on iPhone, iPad, and Mac * Quick capture and inbox right from the Mac menu bar * Links get titles, icons, and previews automatically, all generated on your device * Tag things to keep them organized, with colors that sync * Favorite the really important things * Set up patterns to tidy long website titles, making it easier to read on smaller screens * Inbox plus archive keeps new stuff separate from old * Add to Stash from Shortcuts * Syncs through your iCloud account, nothing stored anywhere else * Privacy switch to turn off link previews entirely if you want zero network requests * Widgets for quickly capturing thoughts or links, and seeing your reading lists from your Home Screen or desktop * Shortcuts support
