Privacy

Tunr is a desktop audio mastering app for macOS and Windows, operated by A. O. Signtech (company registration no. 513915652, an Israeli company with its registered office at Harakefet 9, Zikhron Yaakov, Israel), operating under the brand "Tunr". A. O. Signtech is the data controller for personal information processed through tunr.studio and the Tunr app.

Tunr runs locally on your machine and processes audio on your CPU. Your audio files never leave your computer. This page explains every other piece of data that does: what it is, why we need it, and how to remove it.

What the desktop app collects

Practically nothing. Specifically:

• License-key validation: on first launch after you enter a paid license, Tunr makes a single HTTPS request to tunr.studio/api/activate with your key and a hash of your hardware UUID. The server confirms the key is valid and returns a signed activation token, which Tunr then verifies locally on every launch, with no further network calls.
• Periodic revocation check: roughly once a month, Tunr re-pings tunr.studio/api/status to confirm the token hasn't been revoked (e.g. after a refund). Offline, it skips silently.
• Update check: Tunr asks GitLab for the latest release number once per launch, the same request anyone makes visiting that page in a browser, with no Tunr-specific telemetry attached.

What the desktop app explicitly does not do

• No upload of your audio files, ever.
• No usage telemetry. We don't know which buttons you press, how often you master, or what genres you choose.
• No crash reports unless you opt in (a future version will offer this as a toggle, defaulting to off).
• No third-party trackers, ad SDKs, analytics, or fingerprinting.

What this website collects

tunr.studio uses privacy-respecting, cookieless analytics (Vercel Analytics) to count visits per page. No cross-site tracking, no advertising cookies, no consent banner required. The site sets no third-party tracking cookies. The Paddle checkout opens in an overlay managed by Paddle on their own domain; their privacy practices apply there (see below).

Payments & Paddle

Tunr is sold via Paddle, which acts as the Merchant of Record. Paddle, not A. O. Signtech, is the data controller for your billing data (name, billing address, payment method, invoice history) and is responsible for collecting and remitting tax. After you pay, Paddle passes us only:

• Your email address (to send the license key)
• The order ID and product purchased
• The country your card was issued in (for tax reporting)
• Whether the order was later refunded

We never see, store, or have access to your card number, CVV, full billing address, or bank details. Those remain with Paddle under PCI-DSS Level 1. Paddle's privacy policy: paddle.com/legal/privacy.

What we store

The minimum needed to run your license:

• Your email address (from Paddle).
• Your license key and the hardware-UUID hashes of the machines you activated on (max 2).
• The signed activation tokens we've issued, plus any revocation status.

This data is held on Vercel infrastructure (EU region) and accessed only by A. O. Signtech for the purpose of issuing, validating, and revoking licenses and answering support email.

Email

We send transactional email via Resend: the license-delivery message after purchase, plus rare follow-ups such as update notifications or security advisories. We never sell your email address or use it for third-party marketing.

Your rights

If you're in the EU, UK, or any jurisdiction with similar rules, you have the right to access, correct, delete, export, or restrict processing of your personal data. To exercise any of these, email allexp@gmail.com with the subject "Privacy request." We respond within 30 days, usually within 48 hours. Deleting your account invalidates your license; we'll process a pro-rated refund where applicable.

How long we keep things

• License + activation data: while your license is valid, plus 7 years (tax / audit).
• Email correspondence: 3 years from last reply.
• Anonymised analytics: 90 days, then aggregated.

Changes

We update the "last updated" date above whenever this policy changes. Material changes trigger an email to active license holders 14 days before they take effect.
