Prototo iOS app
The Prototo iOS app collects nothing. No analytics, no tracking, no telemetry, no crash reporting. When you open a prototype link, the app fetches only the prototype data being shared with you. Everything else stays on your device.
Prototo CLI
The Prototo command-line tool collects nothing. No telemetry, no usage reporting, no crash reporting.
prototo.app website
The marketing website at prototo.app uses Google Analytics to count visits and understand which pages get traffic. Standard page-load data (browser, country, referrer) is sent to Google. No personally identifiable information is collected by us.
Share links
When a designer creates a share link with proto share, the link’s metadata (project name, the designer’s display name, and a connection URL) is stored on prototo.app for the duration of the share. This metadata is visible only to anyone who has the share link. Links can be stopped at any time by the designer.
