Sub-processors
Updated September 18, 2026
These are the services that handle your information on our behalf when you read lecronlab.com, join the newsletter, book a call, or try the demo. Each one does the job named here and nothing more. Nothing on this list touches patient data today: every case in the demo is fictitious.
| Service | What it does for us | What it handles | Where it runs |
|---|---|---|---|
| Cloudflare | Serves this site and the demo, runs the newsletter and download forms, stores the newsletter list, and delivers email sent to our addresses | Site traffic, newsletter and download signups, email to us | United States |
| PostHog | Counts page views and clicks on this site, and records how the demo is used, including a replay of each session | Site visits; demo sessions, tied to the email you sign in with | United States |
| Resend | Sends the newsletter | Subscribers' email addresses | United States |
| Cal.com | The scheduler on the booking page | Your name, email, and the answers the booking asks for | United States |
| SMTP2GO | Sends the email we write to you from our lecronlab.com addresses | Email between you and us | Data centers in the United States, Europe, and Australia |
| Google (Gmail) | The mailboxes where email to our addresses lands | Email between you and us | United States |
| Twenty | Our own notes on the labs and practices we talk to. We run the software ourselves; it is never the mailing list, and nothing is written back into it. | Your name and email address, and what was said on a call | A server we rent. The hosting company belongs in this column and is being confirmed, and its name goes here when it is. |
When this list changes
We add a row when a new service starts handling your information and remove one when it stops, and the date at the top moves with it. A lab on a signed agreement with us is told in writing before a new service handles its data.
What this list is not
It is not a claim about patient data. Before any real case goes into Lecron, we agree in writing with your lab what we hold, where it sits, and who may touch it. The security page says where that work stands.
