Privacy Policy

Last updated: May 15, 2026

1. Overview

SwiftDisplay ("we", "us", "our") respects your privacy. This policy explains what data we collect, how we use it, and your rights regarding your information.

2. Information We Collect

2.1 Account Information

Data	Purpose	Retention
Email address	Authentication, notifications	Until account deletion
Name	Display in dashboard	Until account deletion
Password hash	Authentication (bcrypt, never stored in plain text)	Until account deletion
OAuth provider ID	Google/Microsoft sign-in	Until account deletion

2.2 Device Information

Data	Purpose	Retention
Device ID	Unique device identification	Until device removal
IP address	Network connectivity, security	Overwritten each connection
Android version, screen resolution	Compatibility, display optimization	Until device removal
Battery, storage, RAM, CPU, WiFi	Device health monitoring	90 days (rolling)
Device fingerprint (hardware hash)	Prevent trial abuse	Until device removal

2.3 Usage Data

Data	Purpose	Retention
Content play logs	Proof-of-play reporting	90 days
Activity log (API actions)	Audit trail, security	90 days
Screenshots (on-demand)	Remote monitoring	Latest only per device

2.4 Content

Media files (images, videos) you upload are stored on our servers solely to deliver them to your devices. We do not analyze, sell, or share your content.

2.5 Error and Diagnostic Telemetry

Player clients submit error reports automatically so we can fix issues on devices we cannot directly access (smart TVs, embedded signage browsers). Reports may be submitted before a device has paired; in that case only the network IP and user-agent are present, with no device ID.

Data	Purpose	Retention
Browser user-agent string	Identifying which player platforms encounter errors	Rolling buffer (10,000 entries)
Error messages, stack traces, and source-file references	Diagnosing player issues we cannot reproduce in development	Rolling buffer (10,000 entries)
Recent player log entries (up to 50, including filenames of content being played)	Context for the error so we understand what the player was doing	Rolling buffer (10,000 entries)
Screen and viewport dimensions	Diagnosing layout and rendering issues at the device's actual size	Rolling buffer (10,000 entries)
Coarse player state (idle, playing, waiting)	Distinguishing errors during playback vs setup	Rolling buffer (10,000 entries)

This telemetry can be disabled by self-hosters via the PLAYER_DEBUG_REPORTING=off environment variable. On swiftdisplay.com it is on by default.

3. How We Use Your Information

Provide the Service: Deliver content to devices, enable remote management, process subscriptions
Security: Detect unauthorized access, prevent abuse, protect accounts
Communications: Send device offline alerts, subscription notifications, service updates
Improvement: Analyze aggregate usage patterns to improve the Service (no individual tracking)

4. Data Sharing

We do not sell your personal information. We share data only in these limited circumstances:

Service providers: Payment processing (Stripe), email delivery, hosting infrastructure
Team members: If you belong to a team, other team members can see shared devices and content
Legal requirements: When required by law, subpoena, or court order
Business transfers: In the event of a merger, acquisition, or sale of assets

5. Self-Hosted Deployments

If you self-host SwiftDisplay on your own infrastructure:

All data stays on your servers. We have no access to it.
You are the data controller and responsible for compliance with applicable privacy laws.
No telemetry or usage data is sent to us from self-hosted instances. The error and diagnostic telemetry described in Section 2.5 is collected by the self-hosted server itself, not transmitted externally, and can be disabled entirely with PLAYER_DEBUG_REPORTING=off.

6. Data Security

Passwords are hashed with bcrypt (never stored in plain text)
API authentication uses JWT tokens with auto-expiry
All connections use HTTPS/TLS encryption
Android app uses encrypted storage for credentials
Rate limiting protects against brute force attacks
Regular security audits of the codebase

7. Your Rights

You have the right to:

Access: View all data associated with your account from the Settings page
Correction: Update your account information at any time
Deletion: Delete your account and all associated data from Settings
Export: Download your data via the database backup feature (admin) or API
Portability: Export content and reports in standard formats (CSV, PNG, MP4)

8. Cookies and Local Storage

We use localStorage to store your authentication token and preferences (language, theme)
The web player uses a Service Worker for offline content caching
We do not use third-party tracking cookies
Google/Microsoft OAuth may set cookies as part of their authentication flow

9. Children's Privacy

The Service is not intended for use by children under 13. We do not knowingly collect information from children under 13.

10. International Data Transfers

If you access the Service from outside the United States, your data may be transferred to and processed in the United States. By using the Service, you consent to this transfer.

11. Data Retention

Account data: retained until you delete your account
Device telemetry: 90 days (automatically pruned)
Play logs: 90 days (automatically pruned)
Activity logs: 90 days (automatically pruned)
Error and diagnostic telemetry: rolling buffer of the 10,000 most recent entries (oldest pruned on insert)
Content: retained until you delete it or your account
After account deletion: all data removed within 30 days

12. Changes to This Policy

We may update this policy from time to time. We will notify registered users of material changes via email. The "Last updated" date will be revised accordingly.
