1. Acceptance & Service Description
Folio is a paid macOS application designed to help you browse, manage, and back up your personal content on SmugMug. By using this application, you agree to these terms.
2. Payments & Merchant of Record
All payments for Folio are processed by Lemon Squeezy, which acts as the Merchant of Record for all transactions. This means that when you purchase Folio, you are transacting with Lemon Squeezy, not directly with CustomSmug.

3. Free Trial
Folio offers a 7-day free trial. No payment information is required to start the trial. After the trial period expires, you must purchase a license to continue using the application. The trial provides full access to all features.
4. License
A Folio license is a one-time purchase that grants you the right to use the application on your personal devices. The license is managed through Lemon Squeezy's licensing system. License keys are validated at activation and periodically thereafter. The license is non-transferable unless otherwise stated.
5. Refunds
Refunds are handled by Lemon Squeezy and are provided at their sole discretion on a case-by-case basis. If you experience issues with Folio, please contact us first so we can try to resolve the problem. If a refund is necessary, we will process it through Lemon Squeezy. Please contact us or Lemon Squeezy support before initiating a chargeback with your bank.

Privacy Policy
Our Core Principle
We do NOT collect, store, or have access to your photos, metadata, or any analytics/tracking information. Payment and licensing data is handled entirely by Lemon Squeezy — we never see or store your payment details.
What IS Stored Locally (On Your Mac Only)
- Your SmugMug API credentials and OAuth tokens (stored in macOS Keychain)
- App preferences and settings
- Download history (for resume functionality)
- Local troubleshooting logs
All of this data stays on your device and is never transmitted to us or any third party.
AI Auto-Tagging
Folio's AI auto-tagging feature uses Apple's Vision framework and runs entirely on your Mac. No images are uploaded to any external service for analysis. All processing happens locally on your device.
Network Connections
The application only connects to:
api.smugmug.com— SmugMug's official APIsecure.smugmug.com— SmugMug's secure endpointsapi.lemonsqueezy.com— License validation and activation
All connections use HTTPS. There are no connections to third-party analytics, advertising networks, or social media platforms.
Payments & Licensing (Lemon Squeezy)
Folio uses Lemon Squeezy as our Merchant of Record for payment processing and license management. When you purchase a license or activate a trial, Lemon Squeezy may collect:
- Name and email address
- Billing address
- Payment information (credit/debit card details)
- IP address, browser type, and device information
- Transaction and invoice data
This data is collected and processed by Lemon Squeezy directly — we do not store your payment information. Lemon Squeezy is PCI DSS compliant and handles all payment data securely. For details on how Lemon Squeezy handles your data, see their Privacy Policy.
License Validation
Folio periodically connects to Lemon Squeezy's API to validate your license key. This transmits only your license key and basic device information needed for activation. No personal files, photos, or SmugMug data are shared during this process.
Data Security
Your API credentials and OAuth tokens are stored in the macOS Keychain, Apple's secure credential storage system. This ensures your credentials remain secure and are never stored in plain text files.
Your Rights & Data Deletion
You have complete control over your data. To delete all stored information, simply remove the application from your Mac. There is no data stored elsewhere to delete.
Children's Privacy
This application is not directed at users under 13 years of age.
