What this site and your purchases involve, in plain language.
01 Privacy
Last updated 16 October 2026
The short version
No accounts, no ads, no tracking cookies, and I don't sell data.
When you visit this site
- Visit statistics. I use cookie-free analytics from my host, Vercel, to see aggregate numbers such as page views, referring sites, country, and device and browser type. It doesn't build a profile of you or follow you across other sites.
- Your theme choice. If you pick Light, Dark or Matrix, the choice is saved in your own browser so the site remembers it. It never leaves your device.
- Server logs. My host processes standard technical logs, including IP addresses, to run and secure the site.
When you email me
I get your email address and whatever you write. I use it to reply and to support you, and keep it only as long as that takes.
When you buy an app
The payment provider takes your payment details, so I never see your full card number. They share with me your name, email, country and your order and licence details, so I can support you and manage your licence.
Inside the apps
An app may check its licence key online with the payment provider's licence service. What any app sends or stores is described on that app's page.
Your rights
You can ask what I hold about you, ask me to correct it, or ask me to delete it. Email hello [at] heionlabs [dot] com.
Changes
If this changes in a meaningful way, I'll update the date at the top of this page.
