License and Premium

Premium is a single subscription that unlocks sync and the paid features across every product. It is activated per device with a license key.

Generating a key

1. Sign in to the web dashboard.
2. Open Home and generate a license key.
3. Copy the curbext_… key.

The full key is shown once. If you lose it, rotate it and generate a fresh one. Revoking the old key immediately disables it on every device.

Activating a product

Paste the key into the extension's settings (or the mobile app's license card) and validate. The key is checked against your account, and Premium features unlock.

What Premium unlocks

• Encrypted sync across your devices.
• 10 GiB of encrypted object storage.
• CurbPage: unlimited profiles, per-profile passwords, encrypted export, bookmark classification, and shared-vault sync.
• CurbPlace: notes, encrypted attachments, tools, and shared-vault sync.
• CurbTube: watchlist sync and persistent private rooms.
• CurbTime and mobile: encrypted cross-device data.

Free tiers keep every product useful locally. Premium removes the limits and connects your devices.
