Changelog

Deadman switches now support a second trigger action: permanent file deletion. Previously, all switches would share files with beneficiaries when triggered. Now you can choose what happens when you don't check in.

Two Trigger Actions:
• Share (default) - Files are securely shared with your designated beneficiaries
• Delete - Files are permanently deleted from both the database and cloud storage

Key Features:
• Choose trigger action when creating a switch - "Share with beneficiaries" or "Delete permanently"
• Beneficiaries are optional for delete switches - add them if you want others notified that files were deleted
• Owner receives confirmation email listing all deleted files
• Delete switches show a red "Delete" badge throughout the UI so you know exactly what will happen
• Full dark mode support for all notification emails

Important Note:
Delete switches in test mode will actually delete your files (there's no "dry run" for deletion). We recommend uploading test files specifically for testing delete switches.

SMS notifications are coming soon! We're currently waiting for A2P 10DLC carrier approval.

What's new:
• "SMS Coming Soon" banner in the sidebar to keep you informed
• Direct link to notification settings at /settings/notifications
• Add your phone number now so you're ready when we launch
• Full opt-in documentation for carrier compliance

Behind the scenes:
• Improved phone number validation using Google's libphonenumber
• Consolidated phone validation code for better maintainability
• New CDN support for product screenshots

Fixed crash when pausing/resuming deadman switches. When resuming a switch that has been paused past its trigger date (grace period expired), the timer is now automatically reset to give you a fresh countdown instead of triggering immediately. You'll see a message confirming the timer was reset. Switches resumed while still within the grace period will continue their countdown from where they left off.

Implemented complete account deletion functionality that permanently removes all user data from the system. When a user deletes their account, all associated data including files, notes, shares, deadman switches, and recovery codes are automatically cascaded and permanently deleted. An audit log entry is created before deletion to maintain a record that the account existed and was removed by the user.
