Personal Activity Statistics

Making personal effort visible directly addresses the chronic underreporting problem described in the workshops: volunteers stop logging when they cannot see what their logging is for. By surfacing a personal tally of activities, hours, and contacts, the feature converts the act of registration from administrative friction into a personal feedback loop that reinforces continued use of the app. Strategically, this is the lowest-cost building block for the broader retention and recognition story (gamification, Wrapped, certificates). It also gives coordinators a credible answer when peer mentors ask "why should I bother registering?" - increasing data completeness, which in turn improves Bufdir reporting accuracy and the organization's funding case.

Implement as a Personal Stats Screen backed by a Stats Aggregation Service that queries activities (and optionally expenses, attachments, events) filtered to the current user. Aggregations run server-side via the REST API, returning period buckets (week / month / year) and totals; the mobile client renders charts with the existing design token system and WCAG 2.2 AA primitives. Cache the most recent payload in the encrypted local DB so the screen renders offline; refresh on app foreground and after sync outbox drains. No new database tables - reuse existing activities, activity_attachments, and expenses joins. Scope strictly to the logged-in peer mentor's own data; respect role-based access control so coordinators viewing the same screen still see only their own personal numbers (team views live in Coordinator Team Reports).
