Privacy Notice
How this website handles personal data. Last updated November 10, 2026.
This notice covers the Tidemark website at hellotidemark.com and the hosted service. It is run by Michael Kinder.
This website
This site sets no cookies, runs no analytics and loads no third-party scripts, fonts or trackers. It is hosted on our own server at OVHcloud, which, like any web host, sees the address and request of each page load in its server logs. Those logs are rotated automatically and kept only as long as needed to run, secure and debug the site. The only thing stored in your browser is your light or dark theme choice, if you change it.
The documentation lives in the help center of our account portal at account.hellotidemark.com, a separate site from this one. It sets a session cookie and a security (XSRF) cookie when you open it, counts each article view once per visit and stores your answer to “was this helpful” and your search words on our server.
Other Tidemark sites
The community forum is a separate site with its own accounts. This notice does not cover it.
If you use hosted Tidemark Analytics
When you order the hosted service at account.hellotidemark.com, we hold your name, email address, billing details and invoices, and we run a separate installation of Tidemark Analytics for you. We use this to provide and bill for the service, and to contact you about it.
Card details are entered with Stripe or PayPal; we receive only the payment status and the last digits of a card. Billing emails are sent through SendGrid. Your installation’s analytics data is kept in its own database on our server at OVHcloud, with encrypted nightly backups copied to Backblaze. We do not sell it or use it for our own purposes. The analytics are collected without cookies and without storing visitor IP addresses.
Our staff can open your installation only with a read-only, time-limited sign-in that is logged, and only to help you or fix a fault. If you cancel, we delete your installation and its backups are removed as they expire. We keep invoices as long as the law requires for tax and accounting.
If you self-host Tidemark Analytics
If you run the open-source software on your own server, your data stays on that server and you decide what is collected. You are responsible for your own privacy notice. Tidemark Analytics sends nothing to us, apart from an optional update check that asks GitHub for the latest version number and sends no site or visitor data. See how Tidemark Analytics counts visitors for how it is designed.
Your rights
Depending on where you live (for example under the GDPR, UK GDPR or California’s CCPA/CPRA), you can ask to access, correct or delete personal data we hold about you, and to complain to your data protection authority. We hold none about visitors to this site beyond the server logs described above.
Changes
If we change this notice in a way that matters, we will update the date above.
