Crabwise Privacy Policy

Last updated: October 22, 2026

Data collection

Crabwise does not send your library contents or app usage information to the developer. No account is required. Crabwise does not display ads, track you for advertising purposes, or sell personal information. Crabwise does not collect personal data, and the developer does not store or retain any of it on its servers. Your library is stored only on your Mac or in the storage location you choose, and deleting the library folder deletes all of its data.

Data storage

Images, PDFs, web links, collections, tags, and notes are stored in the library folder you choose. Search data and app settings are stored on your device. The developer does not access your library contents.

If you store your library in iCloud Drive or another cloud storage service, the service’s syncing and data handling practices apply. Please review the privacy policy of your chosen service.

Screenshots

Screenshots are taken at your request, with the operating system’s screen recording permission, and saved to your open library. Captured images are not sent to the developer.

Apple Intelligence

Apple Intelligence processes collection and tag suggestions on your device. Your materials and tag information are not sent off your device for classification.

Accessing websites

When you add or preview a web link, or save a web page, Crabwise accesses the specified website to retrieve its title, images, and page content. Adding links through a browser extension works the same way.

As with regular web browsing, the website receives information such as your IP address and browser details. Each website’s privacy policy governs how it handles that information.

Information handled by Apple

Depending on your device’s analytics sharing settings, diagnostic information may be sent to Apple, and the developer may be able to view anonymized, aggregated information. Crabwise does not independently collect or send diagnostic information.

Apple’s Privacy Policy applies to information Apple handles through the App Store and your device’s operating system.

Contact

Contact details and information you provide when making an inquiry are used to respond to your inquiry.

For questions about Crabwise or this policy, please use the contact form.
