Privacy Policy. Local first.

MultiTrim trims audio on your computer. The app never uploads your tracks.

Data can leave in exactly six places: app telemetry you turn on yourself, checkout through Paddle, the account dashboard, support email, the updates email list you can join on this site, and analytics on our websites — cookie-free on multitrim.app, tied to your account on the dashboard. This page covers each one.

MultiTrim reads the files and folders you pick. In the default Replace mode it puts the trimmed file in place of the original and moves the original to your system Trash; Copy mode writes to a separate output folder instead.

All audio processing happens on your computer. We never collect audio content, paths, filenames, tags, waveform data, or exact audio duration.

The app keeps a local settings database on your computer: thresholds, theme, output folder, telemetry choice, license state, and similar preferences. It is not uploaded.

The app asks once whether you want to share anonymous usage data. You can change your answer any time in Settings, and you never need an account or telemetry to use the free app.

If you opt in, the app sends four event types to PostHog's EU servers: app_started, file_trimmed, trim_failed, and batch_completed. Events can include a random anonymous installation ID, app version, operating system, CPU architecture, free or Pro tier, and fixed format or error categories. File events can include rounded numbers for input size, processing time, and throughput. Batch events can include file counts, outcomes, parallelism, and whether you cancelled.

The events never include audio content, paths, filenames, tags, waveform data, exact audio duration, license or payment identifiers, hostname, or raw error messages. The app does not use PostHog person profiles, autocapture, session replay, or any automatic UI tracking.

Offline events wait in a size-limited queue on your computer. Turning telemetry off deletes that queue and the installation ID; opting in again creates a new, unrelated ID. Telemetry never blocks startup, trimming, or licensing.

multitrim.app uses PostHog web analytics in cookieless mode. It counts page views, referrers, and clicks without setting cookies or storing anything in your browser, which is why there is no cookie banner. Data goes to PostHog's EU servers.

Visitors are counted with an anonymous ID that changes every day, so we cannot build a long-term profile of you. The website also receives ordinary server data such as IP address, user agent, and request logs, which we use to serve the site and prevent abuse.

If you sign in at dashboard.multitrim.app, we link dashboard page views, clicks, and similar interaction events to your account ID so we can see where signup, checkout, or license activation goes wrong. The dashboard stores an analytics identifier in your browser alongside its sign-in cookies.

We do not record what you type, and session replay is disabled in the analytics code. Dashboard analytics stay separate from the desktop app's anonymous telemetry and are never joined with it.

Paddle is the merchant of record for direct purchases. During checkout Paddle processes your name, email, billing and payment details, and tax location under its own privacy terms.

We receive enough purchase and license information to unlock Pro, help with a transaction, and meet accounting duties. We never receive your full card number.

If you buy through an app store, that platform handles purchase data instead.

Pro is unlocked with a signed license that the app verifies locally. The license can include a license ID, plan, activation time, optional expiry, and feature flags. The app stores it locally so Pro works without calling home every time.

Deactivating Pro removes the local unlock from that installation. It does not refund or cancel anything.

If you email support, we receive what you send, and we use it to reply, troubleshoot, and keep a record of the conversation.

Do not send audio files, passwords, card numbers, or other sensitive material unless we ask and you are comfortable sharing it.

If you leave your email on multitrim.app, we store it with Resend, the service we send email through. We use it to tell you when a release ships and sometimes to ask what you need from the app. We do not sell the list or share it beyond the two processors named here.

To filter out throwaway and mistyped addresses, the signup check sends the domain part of your address (the part after the @) to Kickbox's disposable-domain service and looks up its public mail records. The part before the @ never leaves our server during this check.

Every email has an unsubscribe link that takes one click. Emailing [email protected] also gets you off the list.

The general approach is to not hold data we do not need: audio stays local, telemetry starts off and is allow-listed, licenses are signed, and the app ships without checkout secrets or private keys.

MultiTrim has not completed a SOC 2 audit and does not claim one. No system is perfectly secure, and you are responsible for your own computer and backups.

Think you found a security issue? Email [email protected] with enough detail to reproduce it.

Local settings and license data stay on your device until you change or delete them, or uninstall the app.

We keep telemetry, analytics, support messages, and licensing records only as long as needed for product work, support, security, accounting, or disputes. Paddle controls its own payment and tax records.

Depending on where you live, you can ask to access, correct, delete, or receive a copy of personal information we hold. Email [email protected]; we may need enough information to verify the request.

Most app data lives on your device, so you can also just manage it yourself: turn telemetry off, deactivate Pro, delete local app data, or uninstall.

When MultiTrim, checkout, telemetry, or the law changes, we update this policy and keep the latest version here with the date above. If a change legally requires notice or consent, we will handle it that way.
