No cookies No stored IP addresses Open source, MIT Hosted, or on your own PHP host Plausible-compatible script
Everything you check, none of the surveillance.
A tidemark is the line a tide leaves on a harbor wall: a record of how high the water reached, kept without keeping the water. Tidemark does that for your website.
Private by design
No cookies and no stored IP addresses. Visitor ids are a salted hash that changes every day, so nobody can be followed from one day to the next. Nothing to disclose, because nothing is kept.
No lock-in
The software is open source. Export a site and import it into any other Tidemark install, so you can start on Cloud and move to your own server later, or the other way around.
Live in about two minutes.
- Create a free account. No credit card, and no server to set up.
- Add your site and paste one line into its
<head>. The script is about 2 KB and works with single-page apps out of the box. - Open the dashboard. It opens by itself after the first pageview.
Paste this into your site
<script defer data-domain="yourdomain.com" src="https://app.tidemarkanalytics.com/js/script.js"></script>
Already use Plausible? The script and Events API follow its conventions, so most sites only change the script address.

Nothing to hide
This website runs on Tidemark Cloud.
Its dashboard is public, so you can see real numbers on the real product instead of a screenshot. Compare Tidemark with Plausible, Umami, Matomo and Fathom.
Questions, answered plainly.
Is the free plan really free?
Yes. Cloud Free gives you one site, 10,000 events a month and six months of history, with every report, filter, goal and shared link. No credit card is asked for. If you go over 10,000 events, new events pause until the month resets and nothing already collected is lost.
What counts as an event?
A pageview or a custom event, such as a signup or a download click. Most small sites use a few thousand a month.
Do I need a cookie banner?
Tidemark sets no cookies and stores no IP addresses or other personal data about visitors. Whether you need a consent banner depends on your jurisdiction and the rest of your site, so check with someone qualified. We do not make legal promises on your behalf.
How does it count visitors without cookies?
A visitor is a salted hash of site, IP address and user agent. The salt changes every day, and the IP address and user agent are never written to the database. Nobody can be followed from one day to the next.
Can I switch from Plausible or move between Cloud and self-hosted?
The tracking script and Events API follow Plausible’s conventions, so in most setups you change the script URL and nothing else. Tidemark can also export a site’s data and import it into another install, which makes moving between Cloud and self-hosted a download and an upload. Importing from Plausible itself is not supported yet.
Can I cancel or get a refund?
Cancel any time from your account. Pro stays active until the end of the period you paid for, and within 30 days of any payment you can ask for a full refund, no questions asked.
Does Tidemark really run on shared hosting?
Yes. It is a PHP application with a bundled set of dependencies. You upload a zip, open /install and follow the steps. It needs PHP 8.3 or newer and a handful of common extensions, and it works with SQLite, MySQL, MariaDB or PostgreSQL. No Node, Docker or SSH is required.
