Privacy Policy

Last updated: 2026-05-20

Specter is a local-first macOS app built by aabergkvist AB (trading as Brilliant Rebels), Sweden. This is a plain-language summary of how your data is handled. Replace or expand this with reviewed legal copy before launch.

Data controller: aabergkvist AB · Swedish company reg. 559317-4948 · VAT SE559317494801 · Stålverksgatan 1, 302 50 Halmstad, Sweden.

Your content

Specter syncs between your Ghost blog and a folder on your Mac. Your posts and credentials stay on your device and travel only between your Mac and your own Ghost blog. We do not operate a server that receives, stores, or processes your content.

Payments

Purchases are handled by Lemon Squeezy, our merchant of record, which processes payment and collects the information needed to complete a sale and issue a license key. See Lemon Squeezy’s privacy policy for details. We receive order and license information (such as your email and license key status) to provide support and manage licenses.

License validation

When you activate Specter Pro, the app contacts Lemon Squeezy’s license API to validate your key. This sends your license key and a machine identifier; it does not send your blog content.

Updates

The app checks for updates via a signed appcast hosted on our site. Update checks are anonymous.
