Margin Reader
Privacy Policy
Margin Reader does not collect, track, sell, or share user data with Lexi Lab. The app is designed as a local-first reader for your own saved articles, notes, highlights, and reading progress.

Data Stored By The App
Margin stores your reading data on your device and in your iCloud Drive container when iCloud Drive is enabled. This can include saved article content, source URLs, notes, highlights, tags, reading progress, reader settings, and local cache files.
Lexi Lab does not operate a server that receives or stores your Margin library.
iCloud Drive
Margin uses Apple's iCloud Drive infrastructure to keep your reading data available across your devices. iCloud data is handled by Apple under Apple's privacy practices and your Apple ID settings.
Saved Websites And System Services
When you save or import an article URL, your device may contact the source website to fetch the article. Dictionary and translation features may use Apple system capabilities where available. Lexi Lab does not receive those requests.
Contact
If you email support, Lexi Lab will receive the information you choose to include in that email, such as your email address, screenshots, device details, or issue description.
Changes
If Margin's privacy behavior changes, this page will be updated before the change is represented in App Store metadata.
