4. AI Scoring Disclaimer

PicSift's quality scores, tier classifications, scene categories, and rankings are generated by machine learning models and represent approximate, automated assessments. They are not professional evaluations.

You acknowledge that:

• Scores are probabilistic estimates, not objective measures of photo quality
• Different scoring models and settings produce different results
• Scene classification, face detection, and duplicate detection may produce incorrect results
• Scores should inform your decisions but are not a substitute for your own judgment

We are not responsible for decisions you make based on PicSift's scores, including deleting, archiving, or sharing photos based on their tier classification.

5. Your Content

You retain all rights to your photos and curation decisions. We do not claim any ownership or license to your content. PicSift does not copy, upload, or transmit your photos.

6. Machine Learning Models

PicSift includes and optionally downloads ML models derived from published academic research, provided under their respective open-source licenses. We may update, replace, or retire models in future versions. Model changes may alter scoring results; re-scoring is available at any time.

You agree not to:

• Reverse-engineer, decompile, or disassemble PicSift or its ML models
• Extract, redistribute, or commercially exploit bundled ML models separately from PicSift
• Use PicSift in any way that violates applicable law
• Misrepresent PicSift's scores as professional assessments or certifications

PicSift is provided "as is" and "as available" without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement.
