Junkmochi is built around one principle: your data stays on your device.
Nothing. The Junkmochi desktop application has no account system, no analytics, and no telemetry. It does not transmit your files, file names, statistics, or any other information to us or to anyone else.
When an installation finishes, the setup program sends a single, anonymous "installed" event so we can count how many people install Junkmochi. It contains only non-personal information — the app version and your Windows version — together with a random one-time identifier that is not tied to you or your device. It carries no name, email, IP-based location, hardware ID, or file path, and geo-lookup is disabled. This happens only once, in the installer, and never again while you use the app. If you're offline, nothing is sent. The event is processed by PostHog (EU region) on our behalf.
You can export or delete this data at any time from the app's Settings, or by uninstalling the app.
To measure "pet health", Junkmochi reads disk usage, the sizes of well-known junk locations (temp folders, browser caches, crash report folders, the Recycle Bin), system uptime, and the list of startup applications. These readings happen locally and never leave your machine.
Our website uses standard measurement tools to understand visits and downloads: the Meta (Facebook) Pixel for ad-campaign measurement, and PostHog (EU region) for basic product analytics. These tools are governed by the respective providers' privacy policies. The website does not require registration and does not ask for personal information.
If you send us a message through the feedback form, we receive the text you wrote, the email address if you chose to add one, and the page it was sent from. It is delivered through PostHog (EU region) on our behalf, without cookies, location lookup or a user profile, whatever you chose in the cookie banner. We use it only to read your feedback and, if you left an email, to reply — never for marketing. To have a message deleted, send us another one through the form asking for it.
The website (not the app) may store these cookies and similar browser storage:
ph_<project key>_posthog (cookie and local storage): an anonymous random ID used to count visits and downloads. Kept for up to 1 year._fbp: lets Meta measure whether our ads lead to downloads. Kept for up to 90 days. Only set when the page is opened from one of our ads.jm-consent (local storage): remembers whether you accepted or declined, so we don't ask again.If you visit from the EU/EEA, the United Kingdom or Switzerland, we ask first: until you accept, the Meta Pixel sends nothing and PostHog stores no cookies (it counts the page view without remembering you). If you decline, PostHog captures nothing at all. Visitors elsewhere can opt out the same way. You can change your choice any time via Cookie settings at the bottom of the home page, or by clearing this site's cookies in your browser.
