Algorithmic Formulations & Privacy Proofs ### 5.1 In-Browser Follower Set Theory Math - **Non-Mutual Accounts**: $$\text{Non-Mutuals} = \{ u \in \text{Following} \mid u \notin \text{Followers} \}$$ - **Lost Followers (Between Export Times $t_1$ and $t_2$)**: $$\text{Lost Followers} = \{ u \in \text{Followers}(t_1) \mid u \notin \text{Followers}(t_2) \}$$ - **Data Security Guarantee**: All parsing of Meta's `followers_1.json` and `following.json` occurs inside client browser V8/JavaScript execution memory. Data is destroyed on tab closure. Zero network packets containing follower handles are dispatched to SnapVaults servers. ### 5.2 Engagement Rate Calculation - **Industry Standard Formula**: $$\text{Engagement Rate (\%)} = \left(\frac{\text{Average Likes} + \text{Average Comments}}{\text{Follower Count}}\right) \times 100$$ - **Niche Benchmarks**: - Lifestyle & Fashion: 1.8% - Tech & SaaS: 2.4% - Fitness & Health: 3.1% - High Performance Threshold: > 4.5% ### 5.3 HTML5 Canvas Tile Geometry - **3x3 Grid Slicer**: $$W_{\text{tile}} = \frac{W_{\text{source}}}{3}, \quad H_{\text{tile}} = \frac{H_{\text{source}}}{3}$$ Tiles are saved in reverse upload order ($T_9, T_8, \dots, T_1$) so the primary image displays correctly on the user's Instagram 3-column feed. - **Seamless Panorama Splitter**: $$W_{\text{slide}} = \frac{W_{\text{source}}}{N}, \quad H_{\text{slide}} = \frac{W_{\text{slide}} \times 5}{4}$$ Each slide adheres precisely to Instagram's standard 4:5 portrait ratio (1080x1350) with zero overlap and zero pixel truncation. --- ## 6.
