Privacy policy

Last updated: 25 October 2026

This policy explains what personal data we collect on livecompanion.app and through the LiveCompanion licence check, why, and what your rights are under the General Data Protection Regulation (GDPR).

Data controller

Sinewave Audio SAS, 8 rue Maurice Bokanowski, 92600 Asnières-sur-Seine, France, SIREN 918 698 101, represented by its President, Kevin Larquier. Contact for any privacy question: contact@sinewaveaudio.fr.

What we collect and why

• Your account: email address and password (stored only as a hash). Used to log you in and to send you account emails. Legal basis: performance of the contract.
• Your licences and trial: tier, licence key, purchase and expiry dates, and the Macs you activate (a technical identifier, the Mac's name, model and macOS version). Used to deliver your licence, enforce the one-Mac rule, and let you manage your Macs. Legal basis: performance of the contract.
• Orders: the Paddle transaction number, linked to your account, so we can deliver what you bought and handle support. Legal basis: performance of the contract and our accounting obligations.
• Messages you send us: your email and its content, to answer you. Legal basis: our legitimate interest in providing support.
• Technical logs: IP address, browser and pages requested, kept by our host for security and to keep the site working. Legal basis: our legitimate interest in securing the service.

We do not collect your card or bank details. We do not sell your data, we do not use it for advertising, and we do not use analytics or advertising trackers on this website.

Payments: Paddle

Purchases are made through Paddle.com, which is the Merchant of Record for our orders. Paddle collects your payment details, billing address and country to take the payment, calculate sales tax, issue the invoice and prevent fraud. Paddle acts as an independent data controller for this data, under its own privacy policy. Paddle sends us the transaction details we need to deliver your licence (transaction number, product, your email and country).

The LiveCompanion app

The app contacts our licence server (Keygen) to activate your Mac and check your licence from time to time. It sends your licence key and the Mac details listed above. Audio, transcriptions, setlists and show recordings are processed on your Mac and on your local network (for example with LiveCompanion Viewer); they are not sent to us.

Service providers

We use the following processors, which handle data only on our instructions and under a data processing agreement:

• Supabase Inc.: Account login and database (email, password hash, licence records). Data stored in the European Union. Privacy policy.
• Keygen LLC: Licence keys and activated Macs (licence key, Mac identifier, Mac name and model, activation dates). United States. Privacy policy.
• Resend (Plus Five Five, Inc.): Sending emails: account confirmation, password reset, licence emails. United States. Privacy policy.
• Vercel Inc.: Website hosting (technical logs such as IP address and browser). United States, with servers in the EU. Privacy policy.

When data is transferred outside the European Union, it is protected by the EU-US Data Privacy Framework where the provider is certified, or by the European Commission's standard contractual clauses.

How long we keep data

• Account and licence data: as long as your account exists. A licence stays valid for life, so we keep it until you delete your account.
• Records linked to an order: 10 years, as required by French accounting law.
• Support emails: 3 years after our last exchange.
• Technical logs: a few days to a few weeks, depending on the host's settings.

Cookies

We only use cookies that are strictly necessary: they keep you logged in to your account. They do not need your consent. On the checkout page, Paddle may set its own cookies to process the payment and prevent fraud.

Your rights

You can access, correct or delete your data, ask for a copy in a portable format, object to processing based on our legitimate interest, and restrict processing. To use these rights or delete your account, write to contact@sinewaveaudio.fr from the email address of your account. We answer within one month. Deleting your account deactivates your licences.

If you think your rights are not respected, you can file a complaint with the French data protection authority, the CNIL (www.cnil.fr), or with the authority of your country.

Changes

We may update this policy. The date at the top shows the latest version. We will email you about important changes.
