Collect only what demonstrably improves guidance quality, and measure that improvement. If a single skill profile and role preference outperform full work histories for resume advice, keep the shorter path. Avoid storing raw transcripts when summary embeddings with differential privacy suffice for personalization. Minimization lowers costs, reduces breach impact, and creates cleaner experiences that respect attention as much as information.
Push sensitive operations to the user’s device when feasible, such as local redaction of names before cloud analysis or on-device inference for quick intent detection. Combine this with selective sync, allowing users to keep certain artifacts offline. These design choices not only mitigate exposure but also improve responsiveness, making privacy feel like performance rather than a trade‑off that slows progress.
Ask for permission only when there is clear benefit, with a short explanation and an honest alternative. Use examples, not abstractions: “Allow saving this mock interview to track progress over time,” with a no‑save option that still delivers value. Avoid bundling unrelated choices. When people feel informed and unpressured, acceptance becomes meaningful, and declines remain respected without penalties or hidden detours.
Provide a visible privacy hub with pause, delete, and export buttons that act instantly and report results. Offer undo windows for accidental deletions and confirm destructive actions in calm language. Reflect changes in the conversation itself—acknowledging new limits and suggesting alternative paths. Empowered users experiment more, share more appropriately, and trust the system to adapt when their circumstances evolve.
