After install every Pro feature is open for 7 days — no card, no sign-up; the AI assistant gets up to 30 requests. Then the extension switches to the free version; your data and templates stay.
A Pro key looks like SAVO-XXXX-XXXX-XXXX. It arrives by email after payment and is shown in your account. If you pay in Chrome, Edge or another Chromium browser with Grabsavo installed, the key activates itself. Otherwise: panel → “Pro” → “I have a key”.
A key works in 3 browsers at a time. Unlink a device in your account. Offline, Pro keeps working for at least 7 days.
