Overview

Families already store critical information somewhere, but it is usually split across paper folders, cloud drives, text threads, and the memory of one responsible person. That makes it hard to find documents when they matter, and even harder to preserve stories, recipes, photos, and health context across generations.

We designed KeepSake as a shared family archive that treats documents and memories as part of the same system. The concept combined secure storage, permission-based sharing, family profiles, and legacy planning in one place.

60 survey respondents
15 user interviews
2 rounds of testing
5 core product surfaces

The Core Problem

Traditional ways of sharing family knowledge are fragmented, insecure, or inaccessible to the people who need them most. Important files may live in one folder, while personal history lives in photos, recipes, or stories that never make it into a system at all.

We started with a question about secure records, but our research revealed a more human one: how might families preserve information that is both practical and meaningful?

Sprint Structure

This was a six-week student-led design sprint with clear ownership by week, which made it easier to move quickly while still handing off work between research, synthesis, testing, and visual refinement.

Week 1

Research

Surveys, interviews, and competitive analysis established the initial problem space around document management.

Week 2

Synthesis

I led affinity mapping, information architecture, and low-fidelity exploration to define what the product should actually be.

Weeks 3 to 4

Mid-Fi + Testing

The team turned the structure into prototype flows and pressure-tested clarity, security, and navigation with users.

Weeks 5 to 6

Hi-Fi Refinement

We finalized design systems, polished the product language, and integrated usability feedback into the final concept.

Research That Changed the Product

Our original framing leaned heavily toward storing high-stakes documents. That stayed important, but the stronger signal from research was emotional continuity. Users wanted a place for confidential forms and a place for family memorabilia, not two separate products.

Survey participants were cautious about uploading sensitive files online, but they became more open when multiple layers of security were present. Interview participants pushed the concept even further by describing a desire to preserve photos, recipes, timelines, and stories that could be passed down over time.

Key Research Goals

Identify pain points
How people manage sensitive family files today, and where trust breaks down.
Understand platform preferences
What would make people willing to use a digital archive instead of paper or ad hoc storage.
Design for safety and clarity
How to make the experience feel secure without making it overwhelming.

Main Insight

The opportunity was not just "store documents online." It was to create one system for records, memories, and legacy handoff. That shift gave the product both stronger utility and a more differentiated emotional reason to exist.

We translated research into personas that reflected both practical needs, like secure access to records, and emotional needs, like preserving family stories and memorabilia.

How We Synthesized the Problem

Affinity mapping helped us organize findings into themes like security, accessibility, habits, organization, and emotional value. That work made it easier to see where people were aligned and where the product needed to balance competing needs.

From there, I helped build the information architecture for five primary surfaces: onboarding, dashboard, documents, family tree, and profile settings. The goal was to create a product that felt coherent even though it was solving for both archival storage and family storytelling.

The concept brought together secure documents, family profiles, and shared history into one experience instead of separating them into disconnected tools.

Product Direction and Key Flows

1. Secure onboarding

We prioritized trust early. The onboarding flow introduced identity verification, a four-digit access pin, and visible progress cues so the security model felt intentional rather than hidden.

2. Documents with permissions

Document upload and sharing focused on clarity. Users needed folder organization, permission controls, and confidence that the right file was reaching the right family member.

3. Family tree as archive

The family tree became more than genealogy. It was designed as a way to navigate profiles, timelines, photos, memorabilia, and health context through relationships.

4. Profile settings for control

Privacy, accessibility, legacy access, linked accounts, and security settings all lived in one place so users could feel ownership over what was shared and with whom.

Testing and Iteration

After mid-fidelity prototyping, the team ran two rounds of usability testing: one with five design students at UC Davis and one with two family members for more real-world perspective. We tested whether onboarding felt appropriate for the product, whether document sharing felt secure, whether family-tree navigation was understandable, and whether profile settings felt usable instead of intimidating.

The biggest takeaway was that users accepted stronger security when the logic was visible and the flow stayed clear. Trust did not come from simply adding more controls. It came from explaining the system and sequencing it in a way that felt understandable.

Final Concept

The high-fidelity concept leaned into a calm, minimal interface with green as the main accent to signal trust, stability, and continuity. The final design emphasized five connected interactions: onboarding, dashboard, documents, family tree, and profile settings.

Verify identity + four-digit pin
Security mechanisms were made explicit to support trust around confidential files.
Granular sharing controls
Users could choose who received access and what level of access they had.
Legacy access and linked accounts
The concept accounted for emergencies, caregivers, minors, and family administration.
Memorabilia and medical context in one system
The archive was designed to support both practical needs and generational storytelling.

Challenges

The hardest design tension was balancing security with ease of access. A meaningful family archive needs privacy controls, but it also has to be usable by people with different levels of technical confidence.

Another challenge was conceptual: we were effectively connecting two products, a secure document vault and a family-memory platform, into one experience. That required us to keep revisiting our how-might-we statements, user flows, and priorities as the concept evolved.

What I Took Away

This project reinforced how non-linear design work really is. The strongest version of the concept did not come from pushing forward on the original idea. It came from listening closely enough to pivot when the research revealed a deeper user need.

If we had more time, I would explore richer document-viewing experiences, more tailored micro-interactions for different artifact types like recipes and certificates, and a responsive mobile-to-desktop system that made family collaboration feel even more alive.
