Website privacy

Last updated: July 2026. This website is intentionally simple: it introduces the app, publishes guides, and lets you preview a filter locally in your browser.

Online filter demo

An image selected on the online demo is read and processed in the current browser tab. The page uses Canvas to create a preview and does not upload the image to our server or build an image database. The page does not retain the image after you close it.

Analytics and external services

This site does not use advertising trackers or visitor cookies. To understand content performance and download conversion, the server records page visits and App Store button clicks, including time, page path, IP address, country/region, and button placement. Location is estimated by Cloudflare from the network address and may be inaccurate.

Raw IP events are retained for up to 30 days to calculate unique visits, investigate unusual traffic, and understand download sources. Daily and page aggregates without IP addresses may be retained longer. The data is not sold or used for third-party advertising and is available only through a password-protected internal dashboard.

When you follow App Store, privacy policy, or terms links, you leave this site and enter the relevant third-party service, which has its own privacy rules.

App privacy policy

The app’s camera, photo library, subscription, and data handling are governed by the permission prompts in the app and its official privacy policy. Read the official app privacy policy。
