Cookies are only part of browser storage
Websites can use cookies, local storage, session storage, and similar browser technologies to remember information. This notice covers all of them, not only traditional cookies.
What Matcha uses today
- Essential account and product storage: information needed for authentication, security, language or display preferences, saved reading state, and other requested product functions.
- Session-scoped analytics storage: a random identifier stored in session storage so we can understand a sequence of events during one browser session. It is not an advertising ID and is not designed to follow a child across sessions or other websites.
- Campaign attribution: UTM campaign information or an external referring hostname may be kept for the current browser session so we can understand which parent-facing campaigns lead to useful product visits.
- First-party analytics requests: Matcha sends privacy-bounded usage and performance events to our own analytics endpoint. The event record is designed not to contain account IDs, child-profile IDs, email addresses, full names, exact ages, raw prompts, photos, voice recordings, or precise geolocation.
What we do not use on child-facing experiences
- Behavioural advertising cookies or advertising identifiers.
- Meta Pixel, Google Ads remarketing, or equivalent cross-site advertising trackers.
- Session-replay or keystroke-recording tools.
- Browser fingerprinting intended to recognize a child across sessions.
Why we still measure usage
Good children's products need evidence. We measure things like page performance, story starts and completions, narration failures, feature usage, and checkout funnels so we can find friction and improve the experience. We prefer aggregate and session-level evidence over persistent individual tracking.
Your choices
You can clear or block browser storage in your browser settings. Blocking essential storage may prevent sign-in, saved progress, language preferences, or other requested features from working properly. Because our current child-safe product analytics is first-party, limited to internal product operation and improvement, and does not use advertising cookies, we do not ask children to make advertising-tracking choices inside the learning experience.
Future tools
If we introduce a new analytics, marketing, advertising, or session-recording technology, we will review its child-safety and privacy impact before enabling it, update this notice, and obtain consent where applicable law requires it. Adult-only products or creator tools may use a different consent configuration, but identifiers from those tools should not be used to create advertising profiles of child users.
