Your purchase. Your key.
Vivarium is free in beta. Checkout is not open yet; this is the planned purchase and support flow.
Activate a purchase
Once sales open, Lemon Squeezy will include your licence key in the receipt email. Paste it into Vivarium → Profile → Licence, then choose Activate. An internet connection is required for verification.
Recover a key or receipt
Use the same email address you used at checkout. Lemon Squeezy sends a secure sign-in link; your order page contains your key and receipt. Check spam if the email is missing. Never post your licence key publicly.
Manage a subscription
Use the subscription-management link in your receipt or order details to access the provider’s billing portal. The planned monthly licence keeps access until the end of the paid period after cancellation. Lifetime purchases do not renew.
Offline access
The new licensing flow caches a successful verification for up to seven days, never beyond a subscription’s verified expiry. Reconnect periodically to refresh. A temporary server error is not treated as an invalid key.
Need help?
Contact Vivarium with your order reference and a description of the issue. Do not send card numbers or passwords. Refund terms must be finalized before sales open.
