Privacy

Last updated: 8 August 2026

Seryn is the public brand for Seryn Labs, Sole Proprietor, which operates this website.

This website is mostly a set of static files. Normal page loads run no analytics, set no cookies, and load no third-party scripts or fonts. Cloudflare may present a security challenge for suspicious traffic and set a strictly necessary clearance cookie. The host may keep the normal request logs needed to serve and protect the site.

Opening the notify form loads Tally in an iframe. Tally receives request metadata plus the product and source fields. If you submit it, Tally and Seryn receive your email and the time you consented. Seryn uses it only to send one product update.

Opening the support and feedback form loads Tally in an iframe. Tally receives request metadata plus source fields. If you submit it, Tally and Seryn receive the information you provide and any file you upload. Use it only for support details you choose to send.

Purchases and refunds

Mac App Store purchases are processed by Apple. Center Click is a free direct download with no checkout or payment data. Future paid direct purchases may be processed by Paddle. Seryn does not receive your payment card number from Apple or Paddle.

App privacy

Each app states its own data practices on its page. Center Click processes gestures locally and stores preferences locally using macOS UserDefaults. It asks for Accessibility permission so it can post the recognized middle click. It does not inspect other apps' accessibility trees, read on-screen text, or log keystrokes. Gesture detection uses Apple's private MultitouchSupport framework, which Apple may change or remove in a future macOS release.

Center Click local diagnostic logs do not contain keystrokes, screen contents, or gesture contents. Its optional support form opens in your browser without app-supplied context; Tally receives ordinary web-request data and anything you choose to submit. Seryn keeps Center Click support submissions only while needed, then deletes them. Tally says deleted submissions and uploads may remain in Trash for up to 90 days. Full policy: /center-click/privacy/.

Eyelet uses pointer motion, optional system reaction signals, and preferences locally. It has no account, analytics, ad tracking, third-party SDK, crash-reporting SDK, or Eyelet-owned network service. Choosing Share opens the macOS sharing picker only after an explicit action.
