Credits: Free vs Premium

The main differences between Free Credits and Premium Credits are based on cost, validity, and expiration.

Free Credits:
- Can be earned by watching video ads within the Vault (available only in the mobile app).
- Have limited validity, allowing you to use them within 7 days of earning.
- Set expiration: when you send a discreet crush message using free credits, the thread remains active for only 7 days, until your crush/receiver potentially pairs with you.

Premium Credits:
- Can be purchased from the Vault section (available on both the mobile app and web version).
- Have unlimited validity, allowing you to use them at any time.
- No expiration: when you send a discreet crush message using premium credits, the thread remains active indefinitely, until your crush/receiver possibly pairs with you.
