Arcastash

Arcastash is a privacy-first media manager for saving and organizing video, audio, and images. SAVE Open the share sheet on any page in Safari and choose "Arcastash." The app scans the page, finds video, audio, and image candidates, and lets you pick what to save β including saving several items at once (Pro). ORGANIZE Sort saved media into folders. Anything you'd rather keep private can go into the Hidden folder, protected by Face ID / Touch ID (Pro). PLAY Everything you save plays back anytime, with no network needed β video with a custom scrubber, images with pinch-to-zoom, and audio playback, all built in. EXPORT TO PHOTOS Save your videos and images straight to the iOS Photos app with one tap. (Audio files can't be exported, since Photos doesn't support standalone audio.) BUILT-IN BROWSER (Pro) Save directly from pages that require you to be logged in, using the app's own built-in browser. PRIVACY Arcastash contains no advertising SDK and no analytics SDK of any kind. Everything you save, your browsing history, and your Face ID / Touch ID authentication results stay on your device β none of it is ever sent anywhere. As the one exception: when on-device analysis alone can't find anything to save, you can tap "Analyze in the cloud" yourself to try cloud-assisted analysis. This is entirely optional and never runs automatically. Only the URL of the page you're viewing is sent, along with an anonymous device identifier used to track your free usage allowance β never your name, email, or any other information that identifies you. See the Privacy Policy for details. ARCASTASH PRO (one-time purchase, price varies by region) Unlocks the built-in browser, the Hidden folder, multi-item batch saving, and removes the free tier's limits on saved items and folders. Arcastash is a general-purpose tool for saving media from pages you've chosen to open yourself. It does not work with DRM-protected or streaming-protected content, and should not be used in a way that violates a site's terms of service. You're responsible for checking the copyright and terms of anything you save.
