DevGlass Privacy Policy / DevGlass 隐私政策
Last updated: August 3, 2026 · 最后更新：2026年8月3日
DevGlass (“we”, “our”, or “the app”) is a B&W film development timer and reference tool developed by ArgentGlass Lab. We take your privacy seriously.
Information We Collect
DevGlass does not collect, store, or transmit any personal data. All data — including your favorite recipes and development session logs — is stored locally on your device using Apple's SwiftData framework. We have no servers and no access to your data.
Local Backup
You can export your favourites, session logs and other local data as a JSON file from About → Data & Backup, and import one back later. The file is handed to the system Share Sheet or the Files app and goes only where you choose to put it; it never reaches us. There is no cloud sync.
Third-Party Services
DevGlass does not integrate any third-party analytics, advertising, or tracking services.
Notifications
DevGlass may request permission to send local notifications — to alert you during the development timing process, and to remind you when a tracked chemical is nearing the end of its shelf life. These notifications are scheduled and generated entirely on your device; there is no push server and no data is sent externally.
Live Activities
A running development timer can appear as a Live Activity on the Lock Screen and in the Dynamic Island. It is rendered locally by iOS from the timer running in the App, is never updated by remote push, and sends no data to us or to any third party.
Data Sharing
We do not share, sell, or transfer any user data to third parties.
Children's Privacy
DevGlass does not knowingly collect any personal information from children.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date.
