Permission requests affect trust. Unexpected access absent from the listing can surprise users at first use.
Evaluation approach
Ask when needed, explain the function and make refusal consequences predictable.
Application example
A scanner can explain camera access directly without requesting unrelated broad permissions.
Limits and considerations
Persuasive wording cannot make an unnecessary permission necessary.
Does refusal copy pressure users?
Avoid fear or guilt. State which feature cannot work and do not stretch a security rationale to unrelated access.
Checks and decisions
- Verify need
- Choose timing
- Explain refusal
