As little as the software and the shop need.

This page says what information I have about you, why, where it goes and how long I keep it. The short version: I collect as little as the software and the shop need, I don't sell it, I don't advertise with it, and there is no tracking in the plugins.

1. Who I am

Andrew Evans, trading as Helder Audio, Haarlem, the Netherlands (KvK 69763143). I'm responsible for the information described here. Questions or requests: support@helderaudio.com.

2. Visiting helderaudio.com

The site is plain pages, served by Cloudflare. It runs no analytics or tracking, and nothing on a page is loaded from anyone else: the fonts are the site's own. Like any web host, Cloudflare sees your IP address and browser details in order to deliver the page and protect the site from attacks. To tell people from bots, Cloudflare runs a small check in your browser, which may set one cookie, cf_clearance. It is there for security only and holds nothing about who you are. Your browser may also tell Cloudflare if a page fails to load. I don't receive or keep any of it.

When you press Buy, Lemon Squeezy's checkout loads, with its own cookies and its own privacy notice. Nothing of theirs loads before that.

3. Trying and unlocking the plugins

The plugins contact my servers in four cases only, as the license (§8) describes: starting the trial, unlocking, freeing a machine, and checking for updates. What's involved:

• A machine code. A one-way code made from your machine's hardware ID; the ID itself never leaves your machine. It is the same for every Helder Audio plugin on that machine. On its own it doesn't say who you are, but once you unlock, it sits beside your purchase at Lemon Squeezy, so I treat it as personal information.
• Trial records. When a trial starts, I keep the product, the dates and the machine code, so that each product gets one trial per machine. I keep that record for 24 months, then it's deleted automatically.
• Unlocking and freeing a machine. Your code from the receipt, the product name and the machine code go to my unlock server and on to Lemon Squeezy, which counts your five machines. The license that comes back, with your name as the shop has it, is stored only on your machine.
• Update checks. At most once a day per product, and when you ask, the plugin fetches a small version file. It carries no code or identifier of yours; Cloudflare sees your IP address as it does for any web request. You can turn the automatic check off in the plugin.

My own servers don't log or store IP addresses. Cloudflare uses your IP address briefly to stop floods of trial requests. There is no usage tracking, telemetry or crash reporting in the plugins.

Why: to give you the trial and the license you're entitled to (to perform my contract with you), and to stop the trial being reset endlessly (my legitimate interest in being paid for the software).

4. Buying, and the free plugin

Lemon Squeezy sells Helder Audio products as merchant of record: it takes payment, charges VAT, and sends the receipt and your code. For that it is responsible for your payment details under its own privacy notice; I never see your card.

From each purchase, Lemon Squeezy shares with me your name, email address, country, what you bought, the price and your license code. I use them to deliver and support what you bought, handle refunds, move a license when you pass it on, and keep the records Dutch tax law requires.

The free plugin (Tijd) asks for your email address, which Lemon Squeezy collects and passes to me. I use it only to send the download and, rarely, to tell you about an update that matters to Tijd. There is no newsletter.

Why: to perform my contract with you, and the legal obligation to keep business records.

5. Email with me

If you email me, I have what you send. I use it to answer you, and keep it as long as it's useful for supporting your purchase, or as tax law requires where it's part of a sale. My email is hosted by Proton Mail, in Switzerland.

6. Who else handles your information

Only these, and only for the purposes above:

• Cloudflare — hosts the website, the downloads and the unlock server. Based in the US; transfers are covered by the EU–US Data Privacy Framework.
• Lemon Squeezy (part of Stripe) — the shop, as merchant of record, responsible for its own processing under its privacy notice; transfers out of Europe covered by the European Commission's standard contractual clauses.
• Proton (Proton AG) — my email. Based in Switzerland, which the EU recognizes as protecting personal information to its standard.

I don't sell or rent your information, and I don't use it for advertising or profiling.

7. How long I keep it

• Purchase records: seven years, as Dutch tax law requires.
• Trial records: 24 months, then deleted automatically.
• Email correspondence: as long as it's useful for supporting your purchase, then deleted.

8. Your rights

You can ask me for a copy of what I have about you, to correct it, to delete it, to limit how I use it, to object to a use based on my legitimate interest, or to have it sent to you in a portable form. Where I rely on your consent, you can withdraw it at any time. Email me; I answer within a month. Some things I have to keep regardless, such as tax records.

If you're not happy with how I handle your information, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl), or to the authority where you live.

9. Changes

If this page changes in a way that matters, I'll say so on the site, and the date below will change.
