Your documents. The files you create or import are stored in the app’s own folder on your device. They leave the device only when you share or export them yourself, through the iOS share sheet, the Files app or iCloud Drive, and then only to the destination you choose. The apps have no server and never upload anything.
Photos. PhyloSketch App can import a picture through the system photo picker. The picker runs outside the app and hands over only the single picture you select; the app has no access to your photo library.
Clipboard. When you choose to paste, the apps read the clipboard to import text; they write to it only when you copy something.
Settings. Preferences such as the dark-mode setting and recently used options are kept in the app’s private storage on the device.
The apps contain no analytics, advertising, tracking or crash-reporting libraries of their own and no accounts or sign-in. They do not access your location, contacts, microphone or camera, and they do not connect to the internet. If you have enabled sharing of analytics and crash data with app developers in your iOS settings, Apple may provide anonymous crash reports to us under Apple’s own privacy terms; we receive no personal data from these.
Purchases and downloads are handled by Apple. We do not receive your name, address or payment details. Apple’s privacy policy applies to those transactions.
The apps are scientific tools and are not directed at children. As they collect no data, no special provisions apply.
Changes to this policy will be published on this page with a new effective date.
Because the apps process no personal data, there is nothing for us to access, correct or delete. If you have a question about privacy, write to the address above.
