Fractune analyses architectural complexity using fractal geometry. Scan a building, get a D-value, and contribute to an open dataset.
Use the box-counting method to calculate the fractal dimension (D-value) of any building facade directly from your camera.
Every analysis contributes to a public dataset. Explore building data at sites.fractune.dk.
No personal data is collected. Contributions are anonymous and validated via Apple's Device Attestation.
All image processing happens locally on your device. Only results and metadata are uploaded — never images.
Fractune respects your privacy. We do not collect any personally identifiable information. All contributions to the public dataset are anonymous and linked solely to a device-generated contributor ID.
You have the right to request deletion of your contributions at any time. Contact us at privacy@fractune.dk with your contributor ID, and we will remove all associated data within 30 days.
