Last updated September 26, 2026
We keep this list short on purpose. Your photographs are not on it, because they never leave your Mac. Our website analytics are not on it either: we run them ourselves, on our own server.
Companies that process data for us
| Who | What for | What they receive | Where |
|---|---|---|---|
| Hetzner Online GmbH | the server that runs our licensing service, this website and its analytics | everything our service holds: account, license, linked Macs, sign-in records, problem reports, logs | Germany (Falkenstein) |
| Resend | sending our email, receiving the email you send us, and holding our newsletter and users' contact lists | your email address, the emails themselves, and which of our lists you are on | United States |
| Linear | tracking problem reports so we can fix them | the problem report, your email address, and pictures you attached, for 60 days at most | United States |
Companies that act for themselves
These companies receive data because of something you do, and decide for themselves how to handle it, under their own privacy policies:
| Who | When |
|---|---|
| Paddle.com Market Limited | when you buy a license — Paddle is the Merchant of Record and handles payment and tax |
| Apple (Apple Maps) | when Katami looks up the place name of a photo's coordinates, or shows a map |
Changes
When we add or replace a company on this page, we update it before the change takes effect and note it below. A new company that will receive customer data is also announced to license holders by email, at least 14 days ahead.
