Privacy policy
Last updated [date] · Version [1.0] · Previous versions
The short version
- Your prescription, PD and frame numbers are worked out in your browser. We never receive them.
- There are no accounts, so we hold no profile about you.
- With your consent, ad partners and a simple visit counter use cookies. You can say no and still use everything.
- Our analytics count actions like "image downloaded". They never include your numbers.
- Partner links tell a shop you came from us. Nothing about your eyes is passed on.
This summary is part of the policy. The full text below is the legal version.
