Privacy Policy

Last updated: May 2026

No uploads. Ever.

Frisbly compresses and converts your images entirely inside your browser using WebAssembly. Your files never leave your device. We do not transmit, store, or process your images on any server. Batch processing and ZIP downloads are also performed entirely in your browser. No images are uploaded to our servers.

What we collect

We collect anonymous, aggregated usage statistics (for example: compression ratio ranges, format choices, session duration) via Vercel Web Analytics. We do not collect filenames, image content, EXIF metadata, email addresses, or any personal identifiers.

Error monitoring

We use Sentry to capture JavaScript errors. Error reports contain stack traces and browser environment details. They do not contain filenames, image data, or personal information. Sentry personal-data transmission is disabled.

Cookies and local storage

Frisbly does not use advertising cookies or third-party tracking cookies. No cookie consent banner is required because we do not run GA4 or similar cross-site tracking.

Third-party services

We use Vercel for hosting and Sentry for error monitoring. Please review their respective privacy policies for details on how they handle infrastructure-level data.
