Activate, verify and renew Pro

Buy Pro through the official Gumroad store, then enter the complete issued license token in first-run onboarding or Settings. Do not post it publicly. Settings shows current entitlement and the Check license online action. Early Access keys resolve to Pro; donations do not automatically issue a license.

The app combines signed local validation with online activation/verification and its existing offline/grace rules. Device slots, expiry, revocation and renewals affect entitlement. Reissue/renewal may be recognized through verified replacement-token refresh; do not ask for repeated reissues just because a UI message looked uncertain. If activation fails, send the error/category and app version privately, not the full token or customer data in a public report.
