Privacy Policy
Last updated: 19 October 2026
huygenlabs.com is the website of Huygen Labs, a one-person software studio. This policy covers this website only. Our products have their own policies: BillVoc’s is at /billvoc/privacy, and Heartkeep’s is on heartkeep.me.
The short version
- No account. There is nothing to sign up for on this site.
- No advertising cookies and no tracking pixels. We do not sell data.
- No analytics as shipped. If that changes, this page changes first.
- If you email us, we have your message and your address — nothing else.
What this site collects
There are no forms, accounts, comments or checkout on this site. You can read every page without telling us anything.
Our hosting provider may keep standard server logs — such as IP address, browser and the page requested — for security and diagnostics. We do not use them to identify, profile or advertise to visitors.
Analytics
As shipped, this site loads no analytics and sets no cookies of its own. If we add privacy-friendly, aggregate measurement later, we will say so here first, keep it limited to page-level events, and give you a way to opt out.
When you email us
If you write to huygenlabs@gmail.com, we receive your address and whatever you send. We use it to reply and to keep a record of the conversation. We do not add you to a mailing list, and we do not sell or share your message. Ask us to delete it and we will.
Links to other sites
This site links to Heartkeep at heartkeep.me and, once it is live, to the Google Play listing for BillVoc. Those sites have their own privacy policies; once you follow a link, their rules apply.
Children
This site is not directed to children under 13, and we do not knowingly collect information from them.
Your control and your rights
Because we hold almost nothing, there is very little to request. If you have emailed us, you can ask what we hold, ask for a copy, ask us to correct it, or ask us to delete it. Write to huygenlabs@gmail.com and we will act on it.
Changes to this policy
If this policy changes, we will update this page and the date above. Material changes will be described plainly, not buried.
