Licensing & privacy
Last updated November 8, 2026
Free stays free
On/off, brightness, Steady, and Breathe with adjustable speed work without a password or activation code. Website downloads require a name and email registration. They do not expire. There is no trial.
Free-download registration
When downloads open, we ask for your name and email before providing the installer. We store one registration per email in a separate LidGlow customer table in our existing Neon database, hosted through Vercel. We keep the registration date, privacy-notice version, optional product-email choice, and file-request counts. We do not track whether you install or use the free app. Registration does not verify ownership of the email address.
These records are available only to authorized LidGlow administrators. We match the registration email to existing Pro licenses to display customer status. Registering again does not overwrite an existing name or product-email preference. Optional product emails require a separate, unchecked opt-in and are not required for the download. The registration form does not send marketing emails automatically.
Download access uses a short-lived, essential cookie that expires after 15 minutes. Contact support to correct or delete a registration or withdraw a product-email opt-in. We retain registrations until deletion is requested or they are no longer needed; purchase and licensing records may be retained separately for those services.
One Pro license, one Mac
Pro unlocks Music, strobe, Codex signals, and automatic rules. A code becomes assigned to the first Mac that activates it. You can reinstall and activate again on that same Mac. It cannot be moved to another Mac. Contact us if a repair changes your Mac’s hardware identity.
Annual Pro access lasts through the paid subscription period. A one-time Pro license keeps working in app versions released within 90 days of purchase; later versions need a new eligible license or an active annual plan. The app occasionally checks it online and stores a signed license in your Mac’s Keychain. Each successful check allows up to 30 days of offline Pro use. After a Mac restart or suspicious date/time change, an online check is required before Pro resumes. If that period ends without a successful check, the app returns to Free until the license can be checked. Revoked licenses return to Free at the next successful check, or when the offline period ends.
What activation sends
Activation sends your code, a cryptographic device identifier derived from your Mac’s hardware identifier, and a public verification key. We keep an additional protected hash of the device identifier, your license status, customer email, and activation history. We do not store raw activation codes. Your Mac’s private key stays in its local, non-synchronizing Keychain.
The licensing service uses Vercel and Neon to host and protect these records. Request metadata, including IP addresses, may be processed for hosting security. Application rate limits use protected hashes rather than storing raw IP addresses in the licensing database. Temporary sign-in and rate-limit records are cleaned up automatically.
Your sound and work stay local
Music analysis happens on your Mac. Audio is not uploaded by LidGlow. Codex signals and app rules are processed locally. The licensing service does not receive your audio, chats, files, app activity, or rule settings.
Payments
When purchases are available, Stripe handles checkout and card details. We receive your email, purchased plan, amount, currency, transaction identifiers, and subscription status to issue and maintain your license. We do not receive your complete card number or security code. Purchase emails are delivered through Postmark. The public installer remains unavailable until release.
