Privacy policy

The product and marketing pages set no cookies and load no analytics, advertising, or tracking script. Vercel, the host, processes standard request logs (for example, IP address and requested path) to serve the site; Index9 does not read them for tracking.

Buying Pro opens Paddle's checkout in an overlay loaded from paddle.com. Paddle collects your payment details, billing address, and email directly, as the Merchant of Record. Index9 never receives or stores your card number. See Paddle's Privacy Policy.

When a purchase completes, Index9 records three fields tied to that transaction: the derived license key, the product name, and the Paddle transaction ID. No name, email, or payment detail is stored by Index9 — Paddle sends the receipt. This record lets the app verify a Pro key later. A refund deletes the record and revokes the key.

Each app sends its license key to index9.dev to confirm it is still valid. The request carries the key only, no device name or identifier, and Index9 does not record which Macs use a key.

Both apps check for signed updates at updates.index9.dev. Whetstone may send content-free usage events (off in Settings → General → Privacy). Windrose sends no usage analytics and has no crash reporter. Neither app sends a device identifier.

Data goes only to the providers needed to run the service: Paddle for payment, Vercel for hosting, and Neon for the license database. Index9 does not sell data or share it for advertising.

index9.dev is not directed at children and does not knowingly collect information from them.
