Your data stays with you.

Height Lens is built so that you don’t have to trust us with anything. There are no accounts, and the comparison tool runs entirely in your browser.

What is stored

• Your current chart is saved in your browser’s local storage so it’s still there when you come back. You can clear it at any time with “Clear All” or by clearing your browser data.
• Your theme preference (light or dark) is saved the same way.
• Images you add are resized in your browser and kept in local storage on your device. They are never sent to our servers.

Share links

When you share a comparison, names and heights are encoded into the link itself. Anyone with the link can see them, so avoid including anything private in names. Images are never included in links.
