Privacy Policy — MailTrace
Last updated: May 6, 2026
Overview
MailTrace is a local photo timestamp watermarking and email archiving tool. We take your privacy seriously.
This app does not collect, store, or transmit any personal user data.
Data Processing
- Photo processing: All watermarking and compression happens entirely on your device. No photos are uploaded to any server.
- Share Extension: When you share photos or screenshots to MailTrace through the iOS share sheet, the images are temporarily stored in the local App Group container so the main app can continue the trace creation workflow. These temporary files are removed after processing and are never uploaded to any server.
- Email sending: Emails are sent through the iOS system mail client. The app never accesses or stores your email password.
- Email addresses: Recipient addresses you configure are stored only in local device storage (UserDefaults) and are never transmitted externally.
- Watermark settings: Custom watermark text is stored only on your device.
Permissions
- Camera: Used solely for taking photos. All processing occurs locally.
- Photo Library: Accessed via the system photo picker. The app cannot browse your full photo library.
Third-Party Services
This app does not integrate any third-party analytics, advertising, or tracking SDKs.
Data Storage
The app stores only the following preferences locally on your device:
- Recipient email addresses (up to 3)
- Watermark suffix text
All data is completely removed when the app is uninstalled.
Children's Privacy
This app is not directed at children under 13 and does not knowingly collect personal information from anyone.
