Cookie-free web analytics

PureMetrix counts your visitors without cookies, without building profiles and without selling any data.

To tell visitors apart for one day, we combine a few technical details of each visit – IP address, browser and your domain – with a random value that changes daily. From this we calculate a hash: a kind of fingerprint that cannot be turned back into the original data. The next day the random value is new, so yesterday's visits can no longer be linked to today's. You lose day-to-day tracking of individual people – and gain simple, privacy-friendly numbers. That fits company websites, documentation and online shops that need reliable totals, not personal profiles.

What we do not do

No cookies or local storage on the visitor's device
No full IP address or browser string stored once the visit has been counted and the country determined
No sale of visitor data to advertisers
No open-source claim – PureMetrix is a commercial, hosted service

How unique visitors are counted

hash(daily_salt + "|" + ip + "|" + user_agent + "|" + hostname)

Inputs. IP address, browser and your domain for that visit.
Hash. Mixed with a daily random salt so it cannot be reversed.
Reset. A new salt every 24 hours, so days do not chain together.

The random value (the “salt”) changes every 24 hours. So each visitor is deliberately counted afresh every day. Details: Privacy Policy and DPA.

Cookie banners

For PureMetrix alone you usually need no cookie banner. Whether your site still needs one depends on your country and your other tools – ads, chat widgets or consent tools, for example. We describe our technology honestly and don't promise a blanket “no cookie banner required”. If in doubt, ask a lawyer.

Where your data is stored

Visitor statistics are processed and stored in the EU, on Hetzner servers. Payments are handled by Stripe. See our Privacy Policy and the DPA.
